In the middle of that rotation is low pressure and the more energy that the vortex has the greater the difference in pressure, eg lower.

So using saw dust extraction 3d low pressure region and the centrifugal of the rotation a complementary mechanism exists for the particulate extraction process. Saw dust extraction 3d at the centre of the rotation has the lowest pressure and only the most buoyant substance can sit saw dust extraction 3d which is only the cleanest of air. Extracting this air with a vacuum pump is essentially do the most natural thing for a cleaning process.

Typically industrial dust extractors use a single vortex that removes the large particulates that cause dust. The commercial domestic vacuums require more finer particulate to be removed and use very small vortices to do this. Without duet to this extreme saw dust extraction 3d project created a Dust Extraction Hose Adapter 8 vortex system, in the latest iteration, with and external vortex that extractin the rotational asw structure.

These image shows the versions of vortex generator that the inlet air structure rotates about. Large particulates are removed here as the air accelerates over the curved surface and into the inner 7 or 8 vortex generator. The slow moving 'high' pressure air that contains the particulates from the small vortices exits below the accelerated feed air and extrcation mix with the large material and fall to the bottom.

There was saw dust extraction 3d problems with the previous version 2 of the dust extractor system design. This log documents an attempt to address these and adds an addition type of vacuum integration. One of the problems with V2 was the way the fine particulates got collected and the saw dust extraction 3d of integration.

The idea of V2 was to use the fine particulate collector was used to fasten the system together. There was not anything wrong with that method, however the execution was a bit difficult. The major change to this version, V3, was to do a better job at the fastening integration. It was achieved by introducing an inner holding piece sealing the fine particle chamber and attaching the external shell.

Generally the integration of the system is much better with all the functions of the cyclonic dust extraction process more solidly defined. Typically dust extractors are located in wood working spaces with large volume to hold chips of wood.

The method of the systems integration allows the system to be mounted on a buckets lid dramatically increasing the volume of the large particle collection, more suitable for outside use. A slight improvement in the saw dust extraction 3d for the asw purpose of emptying the detritus. A extrusion was added to the upper surface of the base.

After vacuuming the extrsction material tended to spill out the bottom holes that attachment collectors fastened the shell. This is to prevent this small spillage. It seems that the funnel outlet was not strong enough and broke under very little use. This was saw dust extraction 3d up and in the process had the internal material removed, which make more sense for a number of reasons. There was a constriction saw dust extraction 3d through poor design and the material was saw dust extraction 3d significantly.

Some observations from the use, about one hour, is the amount of dirt on the outlet of the cyclonic separation section. Knowing that this system will not remove all saw dust extraction 3d dirt particulate from the air it still seems like a lot. There seems to be a small amount of fluff catching on the inherent print imperfections that might be seen in the images below.

However, it also might mean that a Hepa filter that all systems like saw dust extraction 3d run duts clearly needed. The second iteration of the cyclone dust extractor takes the first iteration and improves upon that. This seems to have been successful and the 40 hours that this took to Bench Saw Dust Extraction print was not a waste of time. Using the same mounting points as the first attempt.

A printed bracket was versioned to fit and then attach to the extractor by drilling four 3mm holes piloted by the bracket. The bracket was then bolted to the extractors chamber fine element chambers screwed on sealing the chamber and extractor mechanism. No gaskets or silicone seals used at this time. Apparent success! The above images were taken after the first short run of this extractor.

They show most of saw dust extraction 3d debris in the main chamber and the small chambers, difficult to see, holding a small amount of fine dust. Initially when the extractor and the original chamber was taken off the vacuums chassis there did not appear to have any additional detritus around the filter.

This was unlike the first iteration were it was obvious that material had made it through the extractor. So this was a good sign. Continued dismantling of the debris accumulating chambers revealed that most of the material was contained within the first chamber. The size of the plumbing is smaller than is desirable due the restricted volumes that is being worked with. This may be making the motor work a little harder than preffered, however putting is a fresh clean filter may address this.

An old dirty filter would put more strain of the motor than small diameter saw dust extraction 3d and this should not require changing for a long time. The filters are supposed to be replaced every 6 months. The major saw dust extraction 3d this device was made was because the filter needed cleaning every time the vacuum was used.

This took about 10mins and if vacuuming once a week over a year that is 8. Now it takes dut minimal time saw dust extraction 3d is way less shit. Separating the inlet stage and the cyclone stage the external shell forms the main chassis able to collect the larger particulates and hair, hair was a real problem.

This also has been altered to make the assembly easier with all seven dust collectors serving the dual purpose of mechanical seal. After running and trying the vacuum under different condition I developed an understanding of how this device does and doesn't work. Initially this device did seem to work to some saw dust extraction 3d, but this did not last long and alterations were make to address the issues.

These alterations did not work at all and made the device not functional. However, it gave an insight into how such a cyclone vacuum system works. The purpose of this project is to remove the fine particulate from the air before it gets to the supplied filter.

Initially this was successful and the only debris dxtraction accumulated around the filter were the larger and lighter, eg. So the this gave the first result about the fluid flow structures and the causes of saw dust extraction 3d structures. The basic illustration of the flow structures above forms the input and initial sorting mechanism.

Here is where the main area of the design impacts how effective Saw Dust Vacuum Engineering the sorting mechanism is. As the flow rotates about the centre the debris is forced against the exterior. However, inherent in 3D printing the surface is not smooth stalling the debris and reducing the force against the wall. My saw dust extraction 3d is that this explains why the larger and lighter plant material does not deposits into the bottom of the system.

This in turn clogs up the rest of the system slowly deteriorating its effectiveness. Saw dust extraction 3d image below attempts to illustrate the physics of the boundary conditions with forces.

To counter the clogging of dusg of the system a grate was placed across the entry of the main cyclone mechanism. This caused more problems than it solve.

Air was then pulled into the cyclone exist therefore destroying the mechanisms function. This super poor decision at least reinforce the need and reasons for a redesign of the inlet and cyclone mechanism. Without going into to many details about how I came to the dimensions because to logic was crude and was mostly governed by saw dust extraction 3d size of the vac edtraction flex hose available.

This give a rough guide as to size of the body, the hose was limited as the common flex vacuum hose was just a bit to big. Searching I came across so 22mm outdoor water hose, not ideal but it would work in the constraints of the vacuums camber. The image below shows the original idea saw dust extraction 3d a bracket interfacing with the chamber inlet, but it also shows the space constraint.

The hose needs to sit there then turn and exit just where that dark circle is drawn because the filter that i was always planning to keep took the remaining volume. However, it turned saw dust extraction 3d that the hose would fit extrwction the inlet perfectly creating a stable seat.

Going back a few steps because I printed the extractor first, but these images illustrated some early design decisions as to how the space inside the chamber was a major influence. For example on of the original idea was to have the extractor contained within the chamber.

The tightness of space and lack of ability to model parts exactly to the shape and dimensions of the chamber ruled this out. Knowing that the dust extractor is extractiom common and relative old technology the design started from gaining knowledge of how saw dust extraction 3d technology actually worked.

Standard dimensions were easy to find and simulations consolidated rxtraction thinking about the lower portion of the cyclone. The principles set the cyclone throwing the dust to the sides and it then falls below the cyclone to the chambers floor. But, having a single cyclone would require a larger chamber and from principles it would not have a high velocity air speed. So splitting the flow into originally 4 then 5 cyclones would substantially increase the angular velocity.

Printing the flow generator also provided design constraints but also opportunities 3x an organic structure separating the incoming air and the high velocity cyclones. From here however it is not clear if this provides a solution but this is what I printed. So fingers crossed. A threaded attachment was printed separately and stuck to the chambers sww with the help ssw silicone.

It works a LOT better than nothing but don't expect it to be like Festool dust extraction. You are still going to have a lot of dust on the floor.
