I have made personal friends with a man that served 30 years in the national guard with my father, has been a long time family friend of some of my elder family members, and he has since befriended me for advice on WMO and is being rather generous in return.
We have decided to build our own centrifuge. Mr HB has a metal lathe, a Bridgeport and a few other machines in his shop. He has extended the offer to me, to use whatever I need as much as I need it.
My initial ideas are to build a closed bowl design that is fed at your rate of choice. My idea is to have an inlet port that is fed from the top of the shaft center with dirty oil. Said dirty oil will be ported to the outer circumference of the bowl to eliminate stirring of dirty oil through the lighter cleaner oil at fuge center. There will also be TWO pickup points for "processed" material. I want to have a port that sits at the outer most point of the bowl to drain off water and other liquid contaminates as it is running. The third port will be as close to fuge center as possible and be used to pull off cleaned material from the "top" of the fuge. The difficult part is going to be developing a working rotary seal for the third liquid port. One port to the bowl can run through the center of the shaft to the bowl. The second can also run from the other end of the shaft to the bowl. The third one is going to be the problem. we can also run it through the shaft by drilling another port through the shaft offset from center, but THEN we will have to develop a rotary seal for it as well. I'm going to look for some commercially available multiple port rotary seals, but they may not be cost effective or withstand the high rpm's we are looking to achieve.
The reason I'm going closed bowl design is so I can have the ability to separate material as it is running. The big commercial guys have rigs mounted in their truck that centrifuge out heavier contaminates such as water and antifreeze and send it to another tank as it is running. Closed bowl design will allow me to place valves on my exit ports and use slight pressure on the input to force material out at my desired port.
Anyone currently running an open bowl setup? Anyone have an ideas suggestions advice etc. etc.
This is an idea I am kicking around and we are also seriously considering building an open bowl of the design that can be find from any of the regular suspects.
Look forward to input.
