Pre-wash apparatus for recycling heavily contaminated polymer tubing

A pre-wash apparatus for recycling heavily contaminated polymer tubing, comprising;

• a wash trommel having a generally horizontal axis of rotation and a helical flighting on an inside surface thereof;
• a rinse trommel having a generally horizontal axis of rotation and a helical flighting on an inside surface thereof, said rinse trommel having a perforated wall surface that allows rinse fluid and contaminants to pass therethrough;
• a conveyor positioned between a discharge end of the wash trommel and an entrance end of the rinse trommel for conveying the polymer tubing from the wash trommel to the rinse trommel;
• and
• a float/sink tank having an entrance end adjacent to a point downstream from the entrance end of said rinse trommel, said float/sink tank having a fluid level therein sufficient to permit polymer tubing to float from the entrance end of the tank to a discharge portion thereof while permitting contaminants separated from the polymer tubing to sink to a bottom of the tank.

• a wash trommel having a generally horizontal axis of rotation and a helical flighting on an inside surface thereof;
• a rinse trommel having a generally horizontal axis of rotation and a helical flighting on an inside surface thereof, said rinse trommel having a perforated wall surface that allows rinse fluid and contaminants to pass therethrough;
• a conveyor positioned between a discharge end of the wash trommel and an entrance end of the rinse trommel for conveying the polymer tubing from the wash trommel to the rinse trommel;
• and
• a second funnel-shaped structure positioned below said rinse trommel for guiding fluid and contaminants passing through said perforated wall surface of the rinse trommel to a second separating means for separating the contaminants from the fluid.

• a conveyor positioned between a discharge end of the wash trommel and an entrance end of the rinse trommel for conveying the polymer tubing from the wash trommel to the rinse trommel;
• wherein said conveyor positioned between the wash trommel and the rinse trommel comprises a second open mesh conveyor;
• further comprising a first spray bar positioned above said second open mesh conveyor for spraying a pre-rinse fluid over the polymer tubing.
