Product Description

This attachment is for a vacuum cleaner or on the suction of a blower (see http://shpws.me/L7xg or http://shpws.me/LaQv) is for separating solids or water and catch them in a common soft drink (soda) bottle.

Similar to some well publicised vacuum cleaner designs it adapts a very common piece of industrial plant design (the Cyclone) for use at home - or in this case more likely the garage or shed. If you've been catching your drill cuttings or spills in your household vacuum cleaner and not impressing the master of the house then this gadget is for you ;)

The idea is to catch dirt in the soft drink bottle.

This design features a little ball float valve in case your working with water. Note the density specific gravity of the ball is 0.93 so it just floats in water. If you're developing a lot of foam in the bottle it will probably not be bouyant enough to work to protect your vacuum cleaner. My intention is only to vacuum water with a wet/dry machine as the vauum source rather than convert a dry vacuum to a wet/dry machine. This of you who have used wet/dry machines will understand what a problem they can be to clean if you forget to empty them of "dry" dirt before using them in a wet application. I don't recommend relying on this separator to protect a dry machine - there's a risk of electrocution or machine damage if you do this!

The thread for the drink bottle is UNC1-1/18 which as far as I can tell is the most common thread on the major global brands however, it may not suit every bottle. Some creative use of duct tape or electrical tape will probably solve any connection problems if you're location doesn't have this type of thread!

The theads on the vacuum inlet and outlet are 3/4" BSPP. The reason for this is that this is seems to be the most common garden tap (Faucet) thread. I used the thread as there are many cheap plastic and metal fittings available thru hardware stores that will fit this thread. What appears to vary significantly from brand to brand is vacuum cleaner hose connections. I've made some taper adapters to fit the BSP thread to a cheap vacuum cleaner I have at home but its unlikley the taper will fit all vacuum cleaner hoses. Once again some creative use of standard BSP fittings to pipe with some tape will allow you to connect those ends to the vacuum source and suction hose.

The Tapers I have made are female with a 32mm entry I.D. reducing to 30mm over 35mm distance and a male version that is the complement (ie 30mm at the narrow end and 32mm at the big end over 35mm). You can have a look at them at http://shpws.me/LaQs and http://shpws.me/Lag6

Note that even though the entry and exit threads suit common garden hose fittings, garden hose won't make a great vacuum hose as it's too narrow. Vacuum cleaners rely on air velocity and volume to entrain the dirt. Using a narrow hose restricts the volume flow so  garden hose isn't a winner...

I'm going to keep this product as a Beta until I get my first print back and give it some testing. I'm interested in any comments or feedback on the design.
