(Loved the video) Do some research on microwaves and their affect on food. Speaking of “affect”, ever wonder what word to use?? “Effect” or “Affects”. ?? We can help remember it like this: “A” is for “Anti”. So use “Affect” when speaking of a negative influence on something. Use Effect for all other stuff and things such as special effects. I could have said the above like this: “A” is for “Anti”. So use “Affect” when speaking of a negative *effect* on something. Notice how with”effect” i needed to designate the negative or Anti attribute Soo just remember “A anti. Affect.” And now we will all always member the correct one to use…. Member? Re-member?? Whats up with that? Re-cover Dis-close Un-cover Confusing? Odd? Inverted? “I re-covered the submarine…” Re-covered indeed, as the pieces pictured portrayed quite the pickle. How on earth did they recover the vessel as shown to us (appearing like it had been in an automobile accident…or ok maybe went off a cliff or something); rather than how it should have looked….. which is completely unrecognizable. ripped/shredded/into pieces by the immense pressure of the ocean….

Cyclone separators aren't just used for cleaning. They have been used a lot in places where air is used to move particulate through pipes. They just get the stuff you are moving out of the airflow before it gets sucked into the fan, and deposit the stuff where you want it.

To retain the speed of the air and then separate the high pressure air stream from the particulate, add an internal "shell" shaped internal wall (with tiny holes at sparse tiny holes and more holes closer to the end), such that the air stream expands at an algorithmically fixed rate to pressure-match the exterior of a symmetrical cone inside placed over the inlet to the next stage. The idea is to have a uniform pressure zone across the internal cone, and to have that pressure be maximally physically separate from zones of other pressure. By minimizing the pressure differencials, the particulate will be physically unable to catch sufficient air currents to fight gravity.

I can tell you actually understand this, because your explanation was 100% in your head, not ours. I'm no fluid dynamicist, but I think he's saying the reason the radial velocity drops off so fast is that all the air is rushing up the middle. Now, if you place some kind of layer in between the suction chamber and the vacuum, that has less holes in the middle and more towards the outside, it should even-out the total pressure pulling up on the air into the vacuum, which will reduce local eddies and turbulence, increasing efficiency and dust collection.

@@sl_st That seems to be closer to a modern vacuum cleaner design. I am thinking more of like... having a quasi-cylinder mesh over the out-take, and then a seasnail shell shaped baffle between it and the in-take. With 1-3 walls of the seasnail between the two. This seasnail shaped baffle should have a grid of holes that progress in size starting at the in-take, being very small and infrequent to being larger and more frequent. The holes must have pre-obstacles to act as wind-screens to help prevent particulate from entering them. The holes themselves should be shaped such that particles would have to do a 180 to go through them. Ideally, this will allow particulate from other levels to attempt to go into these and be stopped dead by the higher pressure air. The depth of the seasnail shaped baffle's walls into the bucket should vary as well, they need to be large enough to seperate the areas of differing pressure such that that pressure does not choose to go down rather than through our baffles. This depth can be decreased as it gets closer to the intake. The idea is to chop away at the air-pressure propelling the particulate, while introducing as many physical obstacles as possible. Adding wind-cages to various parts would help too, but would likely get overloaded easily near the in-take. Those wind-cages would have to be shaped such that particulate would want to deflect towards the barrel rather than the air-stream.

For the issue of dust not falling down, I would give the cyclone separator vertical walls (instead of the cone shape which pushes heavy particles upwards via centrifugal force). You'd need to position the exit that dumps the dust into the bucket on the side of the bottom plate, though. (It's position on the bucket lid doesn't really matter.) You don't want it too large in order to avoid stirring up the dust in the bucket, but you also need it to cover at least a small section of the wall where the heavy dust will accumulate.

I really like that you smoothed the inside cone.

I work at a place with huge industrial CNCs, and the remarks about foam made me think: When we mill resin and dense foams, the dust and debris only fill up a few bags but they weigh a ton. When we mill styrofoam, we fill up a dumpster full of trash bags filled to capacity. The dust collector systems we have make this horribly loud noise about 1.5 seconds after they start spinning up, after that it's white noise. So whenever I'm on cleanup duty near them, I always wear earplugs. We don't use the dust collectors for styrofoam debris, as I'm pretty sure they'll go straight to the final stage and clog whatever is in front of the thing that moves the air.

Damn, your tools and camera equipment are a dream! You have every toy a man can wish for

4:17 you could have added inductor in series. Main property of conductor is that it doesnt allow sudden changes in current. So when you swith current would rise on a curve. Higher inductance, rises more slowly. You just take a thick enough wire and make a few turns until its good. This way you dont need a switch and its still dead simple

Heck yes new video rolled out!!! HYPED

I use your cyclone design all the time I have it on my shop vac its amazing for cleaning up drywall dust. using it has tripled the amount of time I can go before I have to knock the dust off the filter on the shop vac

The reason shop vac's are noisy is the same reason they are so good at what they do. They have separate impellers for suction and motor cooling making it safe to suction water with them. Twice as many impellers plus a much more powerful motor and the fact that the cooling impeller's intake doesn't have to suck through 6 feet of hose and a giant expansion chamber that acts like a muffler so you get more of that raw 'blades chopping through air' sound. Household vacuums use the same air for suction and motor cooling. Its usually sucked into the impeller and the exhaust is vented around and through the motor on its way out of the vacuum so there is a lot more restriction to help smooth out those sound waves. If you were able to design a cover for the shop vac that vented both exhausts and the motors cooling intake outside through a window or something you could probably get rid of most of that noise.

Adding diy or purchase comparison at the end of the video will make much more sense for building these things.

Add a longer tube in the center and take more video! I tried to use some Excel calculators our there to design mine. I struggled with what length to make that center tube. mine goes about halfway down the cone. I have no idea if my flow looks like yours at the top or not. I made a frame out of 2x4 and plywood for mine. Rolled a piece of acrylic for cone shape. I drew it in 3D and used a sheet meal program to flatten it. I used that flat patter on the acrylic to make the cone shape and teardrop inlet shape. Then I siliconed a 4" PVC pipe into it tangent to the largest inside diameter. That was trimmed flush inside then. It works, I get tons of dust spirals and very little gets through into my bag filter. Watching your video makes me want to redo it with 3D printed parts!

I love this series of videos!

I have a super simple cyclone-less barrel with the air from the CNC machines fed into the top parallel with the walls of the barrel and the vacuum sucks up through the centre in the lid. It's very efficient even with polystyrene! I used it to empty all of the perlite from my kiln insulation without any dust going into the filter! It's shockingly efficient for such a simple design. I find slower speeds air speeds work a lot better... high flow big bore low pressure

I love these kind of videos :D

I think you'll have more success with a narrower cone. The tighter radius should increase the centripetal force and improve separation, with the steeper walls helping the particles to fall down. You could maybe also try some vanes near the bottom to help direct the particles downwards, though this might disrupt the airflow too much. I'd like to see a two stage system with very small cyclones similar to the Dyson, would be interesting to see how much it helps.

14:33 damn thats some serious vacuum technology. big up sir james dyson

tbh dyson's funky shape actually being functional was the biggest surprise

There are a number of papers people have written on cyclone separators. I did some research into them a while back. A common design is the 1d3c (I think, might be getting the name wrong) where the cylinder section at the top is as tall as its diameter. The cone section is 3 times as tall as the cylinder diameter. I think the exit at the bottom was like 1/4 diameter and the top exit was about the same.

@henryefry

11 ай бұрын

Not sure about how all the complex air flow works, but I think having a taller cylinder section would help with keeping the particles moving fast. Maybe? Idk. Also if you can measure the mass and/or volumetric flow rate, there are equations for how to properly size your separator. I think that might be a reason for the number of smaller ones in the Dyson. For peak performance of those smaller diameter cyclones, they want a lower flow rate.

0:28 you note the imperfection causing a heck of a lot of issues. If you want to 3D print one of these babies, and use it, you have to sand the insides smooth. That, or use ABS and vapor smooth it. The efficiency goes out the window, the rougher the surface is.

The ending cyclone song is so perfect

Looks good !

"screwed and glued" sounds like shorthand for my favorite bedroom technique... ...Where I assemble die-cast miniatures in front of my lovers.

I was waiting for the song.... you didn't disappoint.

Our formula Student team designed an Oil cyclone. To make it more effective, we made the inlet tangential with a quarter rotation of lead in, so the oil (particles) clings better to the outside. Also the coneshaped bottom was formed with a spline, that pointed to a central point and was tangentual to a cylinder on the big end. If you want to improve your disign, this is one possible and easy way to do it.

i once went through the patents on cyclone separators for work. Multistage ones date back to the 1920s

@15:16 - not that it matters much, but if you passed a Shark steamer over the opening of that container, you would knock that static down post haste. I use warm, moist breath to keep my fresh ground coffee from jumping out of the filter and sticking to the inside of the grinder container. I simply breath in to the opening of the grind cup before I pour it in to the melitta filter. No more hopping grounds.

That song at the end was legit lol

Great video as always!!! Keep it up :)

I love that track in the end😂😂😂

note that the difference in size of the cyclones works on the different scale debris- smaller diameter cyclone separates smaller particles - increasing number gives the same flow rate as the single larger unit..

Always enjoy your videos.... Very interesting how all that works.... Thanks. Russ

The funnel at the bottom is only there to collect the dust to the center. To improve performance increase the hight of the clilinder when the air spend more time and a larger area spinning the dust outward.
