When processing wooden blanks, everyone has probably encountered the fact that everything around is covered with a large amount of shavings, sawdust and wood dust. To at least partially get rid of them, various dust collectors, chip suckers, filters and other devices are used. Many power tools and machines have their own dust collectors, while others have special outlets for connecting a vacuum cleaner.

In home workshops it would be better to use special ones. vacuum cleaner than a household one. Firstly, the engine is special. The vacuum cleaner is designed for more than long-term operation, and secondly, as a rule, it is equipped with a hose with a length of 3 m, which significantly simplifies its use with power tools. And yet, the downside of every vacuum cleaner is a small container for garbage.

How to make a cyclone filter with your own hands

Having set out to somehow simplify the work of cleaning a vacuum cleaner and reduce the cost of bags, I began to collect information on this issue. Found a description on the Internet different types simple devices in the form of intermediate dust collectors for a vacuum cleaner. Firstly, these are dust collectors in the form of a mini-cyclone. They perform their function well in collecting dust in a separate container, preventing it from getting into the vacuum cleaner, which increases the service life of the bags tens of times. The process of cleaning the dust collector from debris is also simplified. Ready-made devices are sold through online stores, but their cost is quite high with a very simple design.

Design. I decided to make a mini-cyclone dust collector myself. The author and developer of this design is considered to be Bill Pentz from California. Having developed a serious allergy to fine wood dust, he subsequently devoted a lot of time and effort to fighting both the disease itself and its causes.

The dust collector is a device, the main element of which is an inverted truncated cone, inserted with its lower part into a dust collection container. A tube for connecting to a vacuum cleaner is inserted into the upper part of the dust collector, and on the side, tangentially, there is a tube for connecting the hose from the tool.

When a vacuum cleaner draws in air inside the device, turbulence is formed, and debris, moving along with the air, is thrown back by centrifugal forces to the inner walls of the filter, where they continue to move. But as the cone narrows, the particles collide more often, slow down and, under the influence of gravity, fall into the lower container. And the partially purified air changes direction and exits through a vertically installed pipe and enters the vacuum cleaner.

There are two mandatory requirements for this design. This is, firstly, its tightness, otherwise there will be a sharp loss of suction power and quality of air purification. And, secondly, the rigidity of the container and the cyclone body itself - otherwise it tends to flatten.

There are tables on the Internet with drawings of cyclones for different particle sizes. You can make the cyclone body yourself from galvanized steel or plastic, or you can select a ready-made container of a similar shape. For example, I have seen cyclones made on the basis of a traffic cone (necessarily hard), a plastic flower vase, a tin horn, a large tube of toner from a copy machine, etc. It all depends on what size cyclone is needed. The larger the debris particles, the larger the diameter of the tubes for the connected hoses and the more massive the cyclone itself becomes.

Bill Pentz points out some of the features of his design. So, the smaller the diameter of the cyclone, the greater the load on the vacuum cleaner. And if the garbage container is low and flat, then there is a possibility of debris being sucked out of the container and falling into the vacuum cleaner. When using a container of any shape, it should not be filled to the top with debris.

Choice of material. I decided to use plastic pipes for external sewerage and fittings for them as blanks. Of course, it will not be possible to create a full-fledged cone from them, but I was not the first to try to use them for this purpose. The advantage of this choice is the rigidity of the parts and the tightness of their connections due to the seals. Another plus is that there are various rubber pipe inserts that allow you to easily and tightly connect the vacuum cleaner hose. In addition, if necessary, the structure can be easily disassembled.

For mine, to collect large sawdust and shavings, I made a cyclone from a ∅160 mm pipe. I used ∅50 mm pipes as connectors for the hoses. I would like to draw your attention to the fact that the eccentric adapter from a pipe ∅110 mm to ∅160 mm must be funnel-shaped. I've come across flat ones, but they won't work - nothing will work with them, and the debris will get stuck.

Do-it-yourself cyclone work progress

Operating procedure. In the plug for the ∅160 mm pipe and in the body pipe, I made holes for outlets for hoses. Next, using a heat gun, I glued a piece of ∅50 mm pipe into the plug. It should be located in the middle of the cyclone body and be a couple of centimeters below the side tube, so it is better to first glue a longer pipe into the plug and then cut it in place during assembly.

On the Internet, I found complaints that hot melt adhesive does not stick to PVC pipes, and advice to weld parts using a soldering iron and pieces of the pipe itself. I tried, but didn't do it. Firstly, the glue stuck perfectly to me, and secondly, the smell of melted plastic discouraged anyone from welding anything this way, although the connection would probably be stronger and more accurate.

The difficulty of working with hot-melt adhesive is that it does not spread, and if you lack the skills, the seam will not be very smooth. I had one like this bad experience- To straighten the seam, I decided to heat it with a hairdryer. I got a smooth surface of the adhesive bead, but at the same time the plastic tube itself was deformed and had to be thrown away.

In the next step, I glued a spiral to the inside of the case, which should direct the air flow down to the dust collector. This solution was recommended by Bill Pentz himself - according to him, this almost doubles the efficiency of the cyclone. The spiral with a height of about 20% of the gap should fit tightly to the body and make one turn with a pitch equal to the diameter of the inlet hole for the side pipe.

As a material for it, I used a plastic rod, which I heated with a hairdryer and bent into a spiral shape. (photo 1), and then glued it into the body (photo 2) using a heat gun. Then I glued the side tube (photo 3), the inner end of which is directed slightly downwards.

Once the glue cooled and hardened, I measured and cut the vertical outlet tube so that it was 2-3 cm below the cut of the side tube, and finally assembled the entire structure.

I made a container for garbage from a hard plastic barrel, to the bottom of which I attached wheels - this turned out to be very convenient for cleaning it (photo 4). I cut a viewing window on the side of the barrel and covered it with acrylic glass on hot glue. I reinforced the connection from above with a plastic ring and bolts. Through such a porthole it is convenient to monitor the filling of the container.

I didn’t have a lid for the barrel, so I made it from a piece of countertop that had been waiting in the wings for a long time after installing a sink in the kitchen (photo 5). On the underside of the tabletop, I used a router to select a groove for the edges of the barrel and glued a window seal into it to seal the joint. (photo 6). According to the rules, the hole in the lid should be made in the center, but then I would have problems with placing the cyclone in the workshop, so I made the hole offset. The lid is attached to the barrel using latches from a long-broken vacuum cleaner. I also used a hose from it to connect the cyclone. I would like to draw your attention to the fact that it is better to take hoses from vacuum cleaners. If you take, say, a corrugated pipe for electrical wiring, when you turn on the vacuum cleaner, a whistling and terrible noise appears.

DIY cyclone for vacuum cleaner

Connecting the cyclone to the instrument. Not all tools have an outlet for a vacuum cleaner. So I decided to make a simple, adjustable vacuum cleaner hose holder. For him, I made blanks for levers from scraps of plywood. (photo 7). The holder was supplemented with a sewer clamp for attaching the hose (photo 8). The stand was specially made to be large in size so that it could be secured with a clamp or held with a weight. The holder turned out to be convenient - I use it not only for the vacuum cleaner hose, but also for a portable lamp, laser level and supporting a long workpiece in a horizontal position.

After assembling the cyclone, I conducted several experiments to determine its efficiency. To do this, I sucked up a glass of fine dust, and then measured its volume that fell into the dust collector container. As a result, I was convinced that approximately 95% of all garbage ends up in the barrel, and only very fine dust, and only a small amount, gets into the vacuum cleaner bag. I am quite happy with this result - now I clean the bag 20 times less often, and only for fine dust, which is much easier. And this despite the fact that my design is far from perfect in shape and proportions, which certainly reduces efficiency.

Wiring. After checking the performance of the cyclone, I decided to make a stationary distribution of hoses throughout the workshop, since a three-meter hose is certainly not enough, and a vacuum cleaner with a cyclone is bulky and clumsy, and it is inconvenient to move them around the workshop every time.

Thanks to the fact that they were used standard pipes, we managed to install such wiring in an hour. I pushed the vacuum cleaner and cyclone into the farthest corner, and laid pipes ∅50 mm around the workshop (photo 9).

In the workshop I use a specialized BOSCH green series vacuum cleaner. After four months of using it in tandem with the cyclone, I can say that they generally cope with their task. But I would like to slightly increase the suction power (when working with a jigsaw you have to move the hose almost close to the cutting zone) and reduce the noise level. Since little shavings get into the vacuum cleaner itself, there is an idea to make a more powerful impeller and move it outside the workshop to the street.

I can also say that the suction power of the vacuum cleaner dropped a little when using it with a cyclone, but this is not very noticeable at work. There were doubts that the elements could accumulate static electricity, because the entire structure is plastic, but practically this does not happen, although previously, when collecting fine dust, the hose had to be grounded.

Of course, when using professional pipelines with large outlet openings, this diameter is not enough. It is better to take ∅110 mm or more, but then both the vacuum cleaner and the cyclone must be more powerful. However, for my homework this is quite enough.

The vacuum cleaner hose was firmly secured to a small branch of the pipe ∅50 mm and inserted into in the right place wiring. The remaining wiring outputs are closed with plugs firmly placed on short bends. Moving the hose is a matter of seconds.

During operation I encountered one small problem. If a small pebble (my concrete floors have not been repaired for a long time) or another small but heavy object gets into the hose, it moves through the pipes to the vertical section in front of the cyclone and remains there. When such particles accumulate, other debris clings to them, and a clog can form. Therefore, in front of the vertical section of the wiring, I embedded a camera made of a ∅110 mm pipe with an inspection window. Now all the heavy debris collects there, and by unscrewing the lid it is easy to get out. This is very convenient when fasteners or small detail. It’s simple here - I unscrew the lid, turn on the vacuum cleaner and mix everything that remains in the revision with my hand. Small particles immediately fly into the cyclone container, while large particles remain and are easily removed. Their quantity is usually insignificant, but recently I found a missing screwdriver bit in such garbage.

Also, the inspection hole can be used to temporarily connect a hose ∅100 mm. Just unscrew the lid and you get a finished hole ∅100 mm. Naturally, in this case it is necessary to mute all other wiring inputs. To simplify connection, you can use a flexible adapter (photo 10).

To remotely turn on the vacuum cleaner, I installed a switch next to the hose clamp (photo 11) and additional. It can be used to connect a power tool, then you will definitely not forget to turn on the vacuum cleaner before using the tool - this happens to me often.

I use all of these devices regularly. I'm pleased with the result - there is noticeably less dust in the workshop, making cleaning easier. During this time, I collected several bags of sawdust, and very little debris accumulates in the vacuum cleaner. I want to check the cyclone for collecting small garden debris and dust when cleaning a concrete floor.

I think this design very useful and affordable to make at home.

Sergey Golovkov, Rostov region, Novocherkassk

When carrying out repairs and construction work a lot of garbage appears. Sawdust, shavings, scraps of materials mixed with dust must be removed regularly. Regular sweeping with a mop is excluded due to the specifics of the work, if dust and small particles can stick to the surface, for example, after priming or painting.

An ordinary vacuum cleaner will not cope with such debris or will quickly break down. Household electrical devices designed for medium short-term load.

For such cases, specialized equipment is produced. A construction vacuum cleaner can work for quite a long time without stopping, has significant power, and uses completely different filter systems than household vacuum cleaners.

When should you use a construction vacuum cleaner?

Those who are constantly faced with construction, repair and carpentry work know about the need for timely cleaning of the workplace at the end of the stage. Cleaning can be done multiple times in one day, so it’s reasonable to want to make the process easier for yourself.

Pieces of foam and plastic film, scraps of gypsum board, chipped plaster, dust from cutting aerated concrete - all this debris settles not only on horizontal surfaces, but is also electrified and attached to vertical walls.

Cleaning with a mop and dustpan is not always appropriate due to large areas, and washing will only turn dry dirt into wet slurry, especially in unfinished rooms.

Due to the small size of the dust container, a regular household appliance will quickly become clogged and will have to be continuously cleaned. If large particles get in, there is a high risk of breaking the equipment.

It is in such conditions the best solution will use a construction vacuum cleaner.

Pros and cons of a construction vacuum cleaner

High power allows professional equipment to work without interruption for quite a long time, and a long hose provides access to remote areas without the need to carry the vacuum cleaner or interrupt work.

But it also has disadvantages:

• High price. If periodic or one-time work is required, purchasing a new expensive tool is not practical.
• Large size and weight.

Some craftsmen have come up with a way out of the situation in the form of an additional option to the existing technology. At fairly low costs, you can assemble a cyclone filter for a vacuum cleaner with your own hands. This design will increase the capabilities of an existing conventional household vacuum cleaner.

Making a cyclone with your own hands

There is a huge selection of instructions on the Internet. self-production cyclone filter, including attached drawings and photographs. But they are united by a standard set of components.

So, what do we need:

Assembly instructions.

The main indicator that a cyclone for a vacuum cleaner is assembled correctly with your own hands will be debris collecting at the bottom or settling on the walls of the container, while the suction will be fast and high-quality. Do not forget to check the tightness of the structure.

The history of the cyclone filter

The creator of cyclone filter technology is James Dyson. It was he who first made a filter with operation based on the action of centrifugal force. Why did this device become so popular and in demand that the inventor filed a patent for it?

The filter consists of two chambers. Under the influence of centrifugal force inside the unit, the debris begins to swirl into the funnel. Large trash at the same time, it settles in the first chamber, the outer one, and dust and light debris collects on the inside. This way, clean air comes out through the top hole.

The main advantages of the cyclone filter:

• no need for dust collection bags and their constant replacement;
• compact filter sizes;
• quiet operation;
• An easy-to-remove lid allows you to regularly check the level of contamination and promptly dispose of garbage;
• speed and efficiency of work.

A vacuum cleaner with a cyclone filter can be used both at home and for professional purposes.

Today we will tell you about a cyclone filter for a vacuum cleaner in the workshop, because one of the problems that we have to deal with when working with wood is dust removal. Industrial equipment is quite expensive, so we will make a cyclone with our own hands - it’s not difficult at all.

What is a cyclone and why is it needed?

In a workshop there is almost always a need to remove fairly large debris. Sawdust, small trimmings, metal shavings - all this, in principle, can be caught by a regular vacuum cleaner filter, but it is highly likely to quickly become unusable. In addition, it will not be superfluous to be able to remove liquid waste.

The cyclone filter uses aerodynamic vortex to bind debris different sizes. Spinning in a circle, the debris manages to stick together to such a consistency that it can no longer be carried away by the air flow and settles at the bottom. This effect almost always occurs if the air flow passes through a cylindrical container at sufficient speed.

These types of filters are included in many industrial vacuum cleaners, but their cost is by no means affordable for the average person. At the same time, the range of problems solved using homemade devices, not at all anymore. A homemade cyclone can be used both in conjunction with planes, hammer drills or jigsaws, and for removing sawdust or shavings from various types of machine tools. In the end, even simple cleaning with such a device is much easier, because the bulk of dust and debris settles in a container, from where it can be easily removed.

Difference between wet and dry cyclone

To create a swirling flow, the main requirement is that the air entering the container does not follow the shortest path to exhaust vent. To do this, the inlet pipe must have a special shape and be directed either to the bottom of the container or tangentially to the walls. Using a similar principle, it is recommended to make the exhaust duct rotary, optimally if it is directed towards the lid of the device. The increase in aerodynamic drag due to pipe bends can be neglected.

As already mentioned, a cyclone filter has the potential to remove liquid waste as well. With liquid, everything is somewhat more complicated: the air in the pipe and cyclone is partially rarefied, which promotes the evaporation of moisture and its breaking into very small droplets. Therefore, the inlet pipe must be located as close as possible to the surface of the water or even lowered under it.

Most washing vacuum cleaners introduce air into the water through a diffuser, so any moisture contained in it is effectively dissolved. However, for greater versatility with a minimum number of alterations, it is not recommended to use such a scheme.

Made from scrap materials

The simplest and most affordable option for a cyclone container would be a bucket of paint or other building mixtures. The volume should be comparable to the power of the vacuum cleaner used, approximately one liter for every 80-100 W.

The bucket lid must be intact and fit tightly onto the body of the future cyclone. It will have to be modified by making a couple of holes. Regardless of the material of the bucket, the easiest way to make holes of the required diameter is to use a homemade compass. You need to screw two self-tapping screws into a wooden strip so that their points are 27 mm apart from each other, no more, no less.

The centers of the holes should be marked 40 mm from the edge of the cover, preferably so that they are as far apart as possible. Both metal and plastic are excellently scratched with such a homemade tool, forming smooth edges with virtually no burrs.

The second element of the cyclone will be a set of sewer elbows at 90º and 45º. Let us draw your attention in advance that the position of the corners must correspond to the direction of air flow. Their fastening in the housing cover is carried out according to the following scheme:

1. The elbow is inserted all the way into the side of the socket. Silicone sealant is first applied under the side.
2. WITH reverse side The rubber sealing ring is pulled tightly onto the socket. To be sure, you can additionally compress it with a screw clamp.

The inlet pipe is located with a narrow rotating part inside the bucket, the bell is located with outside almost flush with the lid. The knee needs to be given another 45º turn and directed obliquely downwards and tangentially to the wall of the bucket. If the cyclone is made with wet cleaning in mind, you should extend the outer elbow with a piece of pipe, reducing the distance from the bottom to 10-15 cm.

The exhaust pipe is located in the reverse position and its socket is located under the bucket lid. You also need to insert one elbow into it so that air is taken from the wall or make two turns for suction from under the center of the lid. The latter is preferable. Don’t forget about the O-rings; for a more reliable fixation and to prevent the knees from turning, you can wrap them with plumber’s tape.

How to adapt the device for machines and tools

To be able to draw in waste when using manual and stationary tools, you will need a system of adapters. Typically, a vacuum cleaner hose ends in a curved tube, the diameter of which is comparable to the fittings for dust bags of power tools. As a last resort, you can seal the joint with several layers of double-sided mirror tape wrapped in vinyl tape to eliminate stickiness.

With stationary equipment everything is more complicated. Dust extraction systems have very different configurations, especially for homemade machines, so we can only give a few useful recommendations:

1. If the machine's dust extractor is designed for a 110 mm or larger hose, use plumbing adapters with a 50 mm diameter to connect the corrugated hose of the vacuum cleaner.
2. To connect homemade machines to a dust catcher, it is convenient to use press fittings for 50 mm HDPE pipes.
3. When designing the dust collector housing and outlet, take advantage of the convection flow created by the tool's moving parts for greater efficiency. For example: the pipe for removing sawdust from a circular saw should be directed tangentially to the saw blade.
4. Sometimes it is necessary to provide dust suction from different sides of the workpiece, for example, for a band saw or router. Use 50 mm sewer tees and corrugated drain hoses.

Which vacuum cleaner and connection system to use

Usually, you don’t choose a vacuum cleaner for a homemade cyclone yourself, but use the one that is available. However, there are a number of limitations beyond the power mentioned above. If you want to continue using the vacuum cleaner for domestic purposes, then at a minimum you will need to find an additional hose.

The beauty of the sewer elbows used in the design is that they ideally match the diameter of the most common hoses. Therefore, the spare hose can be safely cut into 2/3 and 1/3, the shorter section should be connected to the vacuum cleaner. The other, longer piece, as is, is tucked into the socket of the cyclone inlet pipe. The maximum that is required in this place is to seal the connection with silicone sealant or plumbing tape, but usually the fit density is quite high. Especially if there is an o-ring.

The video shows another example of making a cyclone for dust removal in a workshop

To pull a short piece of hose onto the exhaust pipe, the outermost part of the corrugated pipe will have to be leveled. Depending on the diameter of the hose, it may be more convenient to tuck it inside. If the straightened edge does not fit slightly onto the pipe, it is recommended to warm it a little with a hairdryer or indirect flame gas burner. The latter is considered excellent option, because this way the connection will be positioned optimally in relation to the direction of the moving flow.

No matter how extensive the range of vacuum cleaners on the market is, not everyone can afford to provide themselves with the appropriate units for industrial and domestic needs. The reason for this is often the high cost of industrial vacuum cleaners. On the one hand, cleaning a garage or workshop takes a lot of time, and on the other hand, a vacuum cleaner costs from $500 to $1000 with a large dust collector and good suction performance. Great solution A homemade vacuum cleaner for the workshop, made by yourself, can be a problem. It’s enough to remember how well we know how to make something. The same principles can be applied when a factory-made home assistant fails in terms of compromising the integrity of filters or dust collection devices. To implement such a project, you will need to be patient and have some available tools that may be gathering dust idle in the far corner of the garage. A homemade vacuum cleaner is easily suitable for cleaning indoors, will help collect construction waste, and will remove dust flying out from under work surface power tools.

Homemade filter for a vacuum cleaner

Initially, before you start stocking up on materials for making the unit, you should clearly define the tasks that the vacuum cleaner must solve. Thus, a waste collection container can be a couple of liters for cleaning in an apartment and other domestic premises, or several tens of liters for cleaning construction waste on work sites or garages. A large barrel or a small bucket from under any building material is perfect for such a container, the main thing is that you have the opportunity to ensure the sealing of this container during the garbage collection process. If the required degree of tightness is not achieved, small fractions of dust sucked in by the air flow will enter the air of the home or air through the openings. working area. The situation is much worse when removing harmful chemical substances And building materials, since in the form of dust or aerosol in the air of the work area they can worsen well-being and harm human health.

In addition to air pollution, poor sealing will result in loss of suction power. If, instead of a garbage container, you decide to make a homemade bag for a vacuum cleaner, it should also hold dust and not let it into the environment.

The size of the cells between the fibers must be such that dust of a certain size is contained within the bag and is not blown back into the room. Of course, that in household premises The type of dust and its size are larger than dust from construction waste and dust flying out from under a working power tool.

How to choose a pump?

The device for creating an air flow can be taken from a ready-made vacuum cleaner that has been used, but for one reason or another is unsuitable for further use, or you can use any pumping device that meets the requirements:

• Must operate at rated load for a long time, sufficient to complete the assigned tasks and all manipulations;
• It must withstand overload, both short-term and long-term, so that a clogged hose does not lead to overheating and failure.
• Must provide sufficient suction force, taking into account installed filters and other obstacles in the path of air flow.

In rooms where high suction power is not required, a regular home vacuum cleaner, for example with a bag dust collector, can serve as a pump. To do this, the bag dust collector is removed, and the necessary components are attached to it.

Making a filter

The optimal solution for creating a filter device for a homemade vacuum cleaner would be a homemade cyclone filter. The manufacturing principle is quite simple: You need to make a structure from a cylinder with two holes for the inlet and outlet of the air flow sucked in by the vacuum cleaner and a truncated cone directed downward. Any material from metal to plastic can be suitable for these purposes. The only requirement for the entire cyclone design is high-quality sealing of all cracks and holes. The reason is the same as for the dust collector: the appearance of a dust fraction in the air and a decrease in the performance of the unit. Consider the option of making a homemade cyclone for a vacuum cleaner from plastic pipes. The only difficulty in manufacturing will be the conical part, which will have to be selected from finished parts or make it yourself. To make it you will need:

1. a pipe with a width of 100 mm and higher, the larger the pipe, the better the performance of the cyclone filter can be obtained;
2. two small diameter pipes for inlet and outlet. On average, pipes from 50 mm and below are taken, depending on the diameter of the working hose.
3. a conical part, a larger diameter that corresponds to the diameter of a large pipe (cylinder).
4. For wide cylinders, 150 mm in diameter or more, a cord or flexible tube of small diameter will be required to guide the filter.
5. A cap that will fit snugly into the top opening of the cylinder.
6. glue or soldering material, sealant.

Homemade cyclone vacuum cleaner Thus, it will turn out much cheaper than the factory one due to the cheap filter, the cost of which will cost 8 - 10 dollars in contrast to the original factory cyclone filter. Initially, a wide pipe is taken, chosen as a cylinder, and cut to the required height (if you were unable to purchase the right size). The holes for the inlet and outlet should be cut as carefully as possible, avoiding chips and uneven edges. If the air suction hole should be located in a horizontal plane, then the air flow outlet hole can be located both on the pipe itself and on the top cover of the cyclone filter. It is worth starting from where it is most convenient to ensure high-quality sealing. If the cover material is much easier to cut and the sealant adheres normally, then it is better to give preference to the cover; otherwise, the outlet should be placed on the body. The main condition is that the outlet pipe must be located above the inlet. This will allow the debris to fall down, allowing only air and fine dust to reach the outlet. To catch such dust, you can also use some homemade filters, for example, fabric ones, or adapt a car filter; this will protect your homemade construction vacuum cleaner from types of debris that are dangerous to the engine.

To create a turbulence in the air flow that is sucked into the cyclone, a flexible hose or cord made of waterproof material should be glued in a spiral pattern over the surface of the cylinder. Such a spiral will increase the efficiency of the cyclone filter. It should be noted that such an addition can only be made for a large diameter pipe, which you can easily penetrate with your hands. The inlet and outlet pipes are fixed in the corresponding holes using sealant, heat shrink, adhesives or pieces of pipe, which are sealed with a soldering iron. The main task of this material is to firmly secure and seal the tubes. The top cover should fit snugly against the edges of the cylinder; you can, if desired, secure it with sealant, but then the process of cleaning the internal surfaces of the cyclone filter from accumulated debris will become more complicated. We should also not forget that the surface can become electrified and accumulate a static charge, which will retain dust. Therefore, it is better to immediately install the lid on the door seal, this will prevent dust from entering the room and will make it possible to freely open the lid at the right time. The conical part can be strengthened with sealant or glue, since it is unlikely to have to be removed. Through the hole in the truncated cone, garbage will spill into the garbage container.

Such a device can be useful not only for those who are thinking about how to make a homemade vacuum cleaner, but also for owners of factory-made working vacuum cleaners. If you are tired of constantly changing the dust collection bag or the filters become clogged, then installing a homemade cyclone will help solve this problem without the extra cost of purchasing a new vacuum cleaner.

If you decide to make an industrial vacuum cleaner, then you can mount a socket on it to connect a power tool, which will allow parallel operation of the vacuum cleaner and the tool. The system can be connected to the socket circuit automatic switching on vacuum cleaner, which will ensure dust suction when starting the tool. In addition, such a system can provide a delay in turning off the vacuum cleaner after opening the power circuit of the power tool. This will allow the industrial vacuum cleaner to collect flying debris and dust within a few seconds after turning off the power tool.

What should you consider when making a homemade vacuum cleaner?

When making homemade vacuum cleaners, some craftsmen, in order to save their own time and effort, include factory parts and spare parts in the unit. In most cases, such a step is quite justified, with the exception of cases of installing filters. For a homemade vacuum cleaner, you should avoid installing the notorious HEPA filters at all costs. These filters work on the principle of trapping small dust particles in the pores of the filter itself. Because of this, as the filter fills with debris, the suction power and, consequently, the quality of cleaning will gradually be lost. All possible attempts to clean such filters do not lead to the expected results, since the dust is not completely blown out, and when washed and washed out, it leads to rotting processes and the development of bacteria. It is clear that these bacteria are blown back into the room during operation; this process is expressed in unpleasant smell while the vacuum cleaner is running.

To optimize the operation of the vacuum cleaner, you can connect two hoses - one for suction, the other for blowing; the blowing hose will allow you to effectively clean various surfaces and hard-to-reach places, since the immediately blown dust will be collected by the suction hose. However, the absence of a filter in a regular vacuum cleaner can also lead to the opposite effect, because in order not to use it, it is necessary to provide the device with an ideal cleaning system, and doing this at home is oh so difficult. So if you need real cleanliness, it’s better to save on something else and choose a reliable and filter-free cleaner to clean both the air and the surfaces. And all this about the separator apparatus! So good luck with choosing and using a vacuum cleaner.

Quite often after various types work remains a large number of fine dust and debris that can only be removed with good vacuum cleaner. A simple home device is not suitable for this. It is necessary to use a high-power industrial vacuum cleaner. You can make a filter for it yourself.

People who constantly work in the construction industry need to clean up a large amount of various small debris and dust. This could be old plaster, leftover foam, drywall, or wood dust. Such debris can settle in a thick layer throughout the room. It is very difficult to sweep this dust with a broom or wipe it with a rag, because due to the large size of the room, such cleaning will take a long time.

Using a vacuum cleaner in this case is optimal. A regular product used at home is not suitable for these purposes. The ingress of wood chips or sawdust will clog the vacuum cleaner or completely disable it. Also, a large amount of fine dust will quickly clog the dust collector, which will need to be cleaned every 20 minutes.

But construction vacuum cleaners are large, inconvenient to use and maintain, and have a very high cost. For this reason, some home craftsmen have learned to increase the capabilities of their household product by equipping it with a specialized cyclone filter. Such dust collectors can be purchased at a hardware store or made at home with your own hands. On the Internet you can find many drawings of dust collectors for woodworking workshops.

Experts highlight the following advantages of cyclone filters:

• no need to constantly buy disposable bags and containers for collecting fine dust;
• small sizes;
• quiet operation of the device;
• when the filter housing is made of transparent plastic, it is possible to monitor its contamination;
• high efficiency.

Operating principle of a cyclone filter

The cyclone consists of several parts:

• pipe branch;
• frame;
• dust collector;
• chamber with membrane filter;
• intake fan.

Dirty air enters the cylindrical body of the product through the pipe. The pipe is located tangentially to the side walls of the housing, so the air flow near the cylinder walls twists in a spiral. Due to centrifugal force, dirt particles are pressed against the body of the device and then fall into a special dust collector. The remaining air with dust particles enters another chamber, which is equipped with several membrane filters. As a result, all collected dust ends up in the receiving fan.

The membrane compartment is the least contaminated and must be cleaned only after cleaning. The collected dust is simply removed from a special storage device, and the device is again ready to perform its duties.

Vacuum cleaners with a similar principle of operation are much cheaper than water ones, but more expensive than membrane ones. For this reason, home craftsmen assemble the cyclone themselves and then connect it to a household vacuum cleaner.

DIY cyclone from scrap materials

It is quite easy to assemble a cyclone filter for a vacuum cleaner with your own hands. It is often necessary when processing wood. Together with a framer or an electric planer, a membrane-type vacuum cleaner gets clogged very quickly and needs to be cleaned frequently, which greatly distracts from the production process. When a master is engaged in carpentry in a small room, then fine sawdust creates a lot of problems. For this purpose, a cyclone was designed and manufactured from simple details, which is not inferior to its factory counterparts.

Materials for production

To make a homemade cyclone, you will need the following materials:

Assembling a cyclone for a household vacuum cleaner

A special bracket for a small air filter, which can be made from metal strip or corners. The air filter must fit very tightly to the plastic lid of the container. Otherwise, dusty air will enter the outlet pipe. Next, the outlet pipe must be sealed tightly on top of the lid. Through it, purified air will flow into the household vacuum cleaner. Experts advise leaving the membrane filter of the household product. This will help keep the fan free from dirt and will not weaken the air flow.

Near the air filter it is worth placing a special dust trap, which is assembled from thin metal sheet. This element is capable of repelling small particles of dirt that do not fall under the influence of gravity, which allows you to clean the filter much less frequently. An old woman's stocking can do the same job, protecting the filter pores from large and light particles of dust.

The homemade inlet pipe must be positioned tangentially to the walls of the housing and slightly tilted towards the bottom of the device. Dirty air will be immediately sent in the right direction. To ensure that the walls of the container do not collapse due to the vacuum environment, they must be well reinforced with a strip of metal. Plastic containers are not able to withstand heavy loads because the material is quite thin. Since the device is large in size, it is worth making a plywood frame, which it would not hurt to equip with small swivel wheels.

Next, you need to properly secure the assembled filter and household vacuum cleaner to the frame. The fastening must ensure quick dismantling in order to clean the container from collected debris. At the end of the work, you need to test the device. All debris should remain at the bottom of the plastic container.

How to make an aqua filter for a vacuum cleaner

When a person does not need a professional construction vacuum cleaner, a water filter for chips can be made in another way. For example, it can be made from an ordinary traffic cone. Any plastic container with thick walls and a well-closing lid will serve as a dust collector. It is worth noting that plastic container acts as an air system, and leakage has a bad effect on the power of the device. It is necessary to cut the support square from the traffic cone. Based on the resulting hole shape, you need to cut out the top cover from plywood.

An outlet pipe is fixed into the top cover using sealant, which should be made from ordinary sewer pipe. This part must be lowered to the middle of the construction cone. When it is raised higher, the dust swirl will be incorrect. If the outlet pipe goes down too low, dirt will be sucked into it.

The narrow part of the traffic cone is also sealed into a circle of plywood, which is attached to the trash compartment. It is worth checking the tightness of all seams and connections several times. An inlet pipe is placed near the upper cut of the cone, into which dirty air will enter.

Next, you need to check that the dust collector is assembled correctly. The outlet pipe must be connected to the inlet of a household vacuum cleaner using a factory hose. Therefore, the nozzle should be selected in accordance with the diameter of the vacuum cleaner hose. The waste collection hose is connected to the inlet pipe of the product. A test run is required. When the device is assembled correctly, all debris will accumulate at the bottom of the plastic container, and the membrane filter of the household vacuum cleaner should remain clean.

You can make the cone shape with your own hands. For example, make it from metal sheet, having previously calculated the layout of the product. An old galvanized metal bucket may also work.
