Abstract
A carriage movable back and forth along a tank of water has an agitator which washes floatable material and moves it to a floating material conveyor at one end of the tank. Denser, sinkable material washed from the floatable material drops onto a sunk material conveyor coursing along the bottom of the tank. The drive of the carriage is reversible and, when excess resistance is met when the carriage is traveling toward the floating material conveyor, the resistance actuates a control to reverse the drive of the carriage.
Claims13
In a separator,
- a tank open at the top and containing liquid of a predetermined specific gravity,
- carriage means movable back and forth along said tank,
- agitator means carried by said carriage means, said agitator means being disposed to contact the upper portion of said liquid in said tank for breaking up and washing a floating pile of relatively heterogeneous floatable and sinkable components,
- reversible drive means for driving said carriage means,
- resistance responsive means for reversing said reversible drive means when said carriage means encounters a predetermined minimum resistance to movement along said tank, and
- conveyor means for removing the floatable components from said tank.
