Cyclone Separator

379009317722Inspired by a video I saw a while I have set about trying to build a cyclone separator.

A cyclone separator is essentially what inspired James Dyson to make the cyclone vacuum cleaner. It works using the simple principal of centrifugal force. Air contaminated with particulate matter is sucked into a conical or cylindrical shaped chamber, the air enters at the top of the chamber parallel with the wall. The air is forced to flow around the curve of the wall, forming a vortex. Through centrifugal force the vortex pushes the particulate matter out to the sides and against the wall of the chamber where it slows down and falls out the bottom of the chamber. The remaining air is sucked out the top by a motor fitted with a fan to create suction.

I built my cyclone separator using an upright vacuum cleaner someone gave me that had been converted for use in a wood workshop, it no longer had a brush bar at the bottom, handle or any tools, just a motor, dust bin, filters and a pipe coming out with a good amount of suction.

The end result was a rather bodged but working cyclone separator, which with a mesh filter would probably be quite effective! I did some testing with polystyrene balls but it happily picked up all the other light pieces on my desk, and wasn’t even that well sealed!

In the process of building this I did a bunch of research and found some other projects that were interesting:

This was the series of videos that inspired this experiment by Matthias Wandel:

I will post the results soon, but it’s good news!

Inside Dyson

Vax

Vax are another UK manufacturer of vacuum cleaners, they provide much less info about their company than Dyson but here above I found out about a Cardboard eco friendly vacuum cleaner they have designed with a student on placement.

Below is an image showing a prototype through to production, perhaps cardboard prototyping is more common than I thought.

One of the stalls was about Cardboard Prototyping by a clever designer/maker from Dyson called Jude Pullen, who calls it Design Modeling, and has produced a series of videos and details about this on his website.

I also did some more research and found some other people showing clever uses for it.

Looking around I found the above and below images of some of their prototypes…

The kind people at the James Dyson Foundation have kindly provided me with a Dyson DC11 vacuum cleaner to destroy, I mean take apart and analyse!

I have ordered some test equipment to allow me to take some measurements of it before and during the disassembly process.

What is the Open Source Vacuum Cleaner?

My final masters project at the RCA will focus on my main interest, and the area of my dissertation.

This project is inspired by the maker community, people who are hacking, tinkering and constructing their own DIY kits and projects to produce useful, bespoke or repaired items for fun and learning. These people have an open and liberal approach to sharing their work.

Over the course of the next two months I am running a series of workshops to kickstart a community effort to build a open source vacuum cleaner, the vacuum cleaner will be designed to be home manufactured using, where possible standard, easily obtainable parts.

I will be running a series of workshops to kick-start the process of creating a community around this object.
