Pumping abrasives peristaltically? Instead of using the usual expensive peristaltic tubing, why not use a common, mass produced tire?

Concrete wears down the rubber in a peristaltic pump. This invention looks at the use of ordinary auto tires as a cheap source for replacement rubber. Steel or synthetic belted tires might prove very durable in pumping. Chances are that road worn radial tires might serve equally well for a pump/ where only the tread has been worn. A nearly cost free source for a peristaltic membrane might then be available world wide. (Using existing tire rim might not hold up with continued use, but might be worthwhile for experimentation).

 

Standard tubeless tire mounting might prove difficult to reseal during a pumping blowout. Keeping the rim clean and getting tire to seal with concrete is asking much. However these situations can be remedied with hydraulic assisted tire removal, tire replacement and tire clamping, (sealing).To improve feasibility, the tire could seal outside the rim. A second external rim edge might clamp the tire, powered by the pump hydraulics. In this scenario, the tire would mount external to main rim. Pump hydraulics would rotationally pry the tire in place. This would be followed by hydraulic clamping with special outer rim. (This is not illustrated).

Below is an upgrade alternative for the animated model above. Please feel free to use these ideas in your own way. My effort as of 2005 was to see if plans could be sent to a machine shop. The drive mechanism -- hydraulic or gears boxes, has been a difficult choice. (My machine-shop friend had some old gear boxes but the rigging needed too much tinkering)

The red parts are a mixer / agitator / impeller. (The stopper plate is not shown in model below. It needs to be bolted to squeeze tire against "rim". Red parts also replaces the "in" tubing, brown part above). Green "rim" parts are cut bent and welded steel. Blue parts: rotating rollers or squeeze tires. (This upgraded rim detail is available. For easy printing on your printer, I can send you "gif" 2D format which your email and www-browser programs can read and print to scale,gif is better than jpg for this).

 

 

 

 

Please do link with this this page or send your photos and report....If you build one! It would be great to show your results here or to link to them on your web site. Be the first in the world to build one! (It might take me a while yet, as my design interest is stronger than my arm or my budget ;-)

Searching Synergy .... .... Free Exchange of Ideas
