Cyclone Flat Pack Kit

[knappers]

No problem Roger.

We get through lots of oil at work, but unfortunately, it's all delivered in drums with a removable plug, rather than a clip on lid. I suspect many potential sources of drums may be the same.

Try the food industry.
Lots of fruit pulp is imported in 60 and 120 litre plastic drums. Some have the circular clamp ring as used in the steel barrels and are fine, others have a coarse screw threaded lid which are a right bast ard to take on and off by hand as you need two arms like a gorilla to grip the barrel and another two to turn the lid DAMHIKT!!

ok ... I've been doing some more thinking (dangerous ! )

how about wall mounted cyclone with wall mounted sealed bin beneath,

in the bottom of the bin is a dust chute that you open to empty into a bin bag, then close and carry on

 

[9fingers]

Should work provided the dust chute seal can be kept clean when emptying so that it reseals.
It will end up quite tall though and might not suit every workshop.

What size ducting are you using from the cyclone to the blower and for the runs from the cyclone to the machines?

Mark

Hi Mark,

Cyclone-blower and blower to filters is 6" flexi. All the fixed ducting is 110mm soil pipe and fittings, 100mm blast gates (which glue in nicely to the bore of 110mm soil pipe with PU foam adhesive), 100mm flexi to machines only reducing to smaller hose if needed for the minimum length practical.
Small bore hose friction really costs a lot in air flow/suction terms.

Oildrums are a lot of work .Look for 'Open top drums' with a lever band fastener. I bought some 15 years ago from a company shipping goods and chattels to Africa and the Caribbean - they had 3 different sizes outside the shop,Clean and cheap

How heavy is one of these oil drums filled with chips and dust? Sounds to me like a two man job to up end the contents into a plastic bag.

Or can you stick a plastic bag inside? Surely it gets sucked up into the cyclone? I think I remember reading someone advocating a bleed pipe (like a bit of garden hose) from the suck side of everything to the space between the bag and the oil drum to equalise the pressure and so prevent bag-suck but thin enough not to affect the overall suck...where you need it.

Morning all

Speaking of drums, this held casting slip for pottery. Steel band to seal the lid and a couple of handles. Worth asking at local potteries / clubs.

A bit small for the pro's but big enough for me.

Cheers

No the bag does not get sucked up if the drum is sealed. I use a bin liner in mine all the time now.

A 60 litre drum of shavings & dust is easily managed; A 200litre one might be a little less easy!
However, a modest timber prep session at the start of the project could easily fill a 60 litre drum.
Another reason to have a short length of clear flexi between cyclone and drum so you can see when it is full.

Thanks Bob. I like the hose separation idea. Any recommendations as to the best place to buy it? Axminster want an arm and a leg and an eBay search only gives opaque hose.

Roger,

I have a scrap 200mm long x 150 diameter, I can send you which is just about enough to go between cyclone and bin - just PM me your address.

Or there is 5m of clear on ebay item 120755091804. That seller is obviously trading in the stuff and might be prepared to sell you a bit less.

That's very kind of you, Bob, but I'll need a bit more than that as my cyclone needs a 6" length to the extractor as well.

 

[PeterBassett]

Have there been any developments on this Chems?

 

[Chems]

Yes, first prototypes been made and tested, doing a run of the full set to get pictures and assembly instructions before opening up the floor. There will be 4 sizes, 150mm, 100mm, 63mm and 50mm each corresponding to the ducting size and there size in relation to that.

As a really rough guide on price as it hasn't all been worked out yet it will range from roughly £100/110 for 150mm down to £50-60 for the 50mm version probably less but still got a few prices to work out.

And a moving pictures speaks a thousands words, heres the 100mm version running, the final versions will be all clear including the top, and it looks a bit messy around the bottom because I mitre fast'ed it to my drum for quick testing.

Prefer if the video was kept just here amongst close UKW friends, I'll get a decent one done before proper launch.

 

[9fingers]

Looks good - especially as there appears to be no air ramp.

How much dust is going into the vac/blower?

Bob

 

[Chems]

0, the extractor is new an still looks it, I'm going to get some good images of that so people dont rely on my word for it.

 

[The Bear]

I'm impressed also.
What is the construction process? When its rolled what happens to the seam, does it get in the way of a smooth airflow round the cyclone?

Mark

 

[PeterBassett]

Hi, that looks great. I'm still a little worried about the bending process however. I assume it would still all be supplied flat? How would we go about it?

Pete

 

[Chems]

Its smooth on the inside so as not to disturb the air flow, bending and assembling is very easy, takes about 5 mins and its best to have 2 people unless you want to enlist the help of some clamps which could be done. It will be supplied flat, and because of that it looks like its going to be fairly cheap to ship, something I was a bit worried about.
