ABSTRACT:
A waste compaction and liquid extraction system is provided. The system includes a tank for containing liquid and solids. The tank has an input port for receiving liquid, and an output port for discharging a mixture of liquid and solids. A rotary disc impeller is mounted in the tank for grinding the solids to form the mixture. The impeller has a rotating blade with inclined and bevelled cutting members. Each cutting member has a helical leading edge. The tank conducts the mixture to the output port. A stationary helical screw is horizontally mounted to the output port of the tank. The screw has a receiving end adjacent to the output port and a discharge end. The screw has a tapered shaft that increases in diameter towards the discharge end. A sieve is provided having a cylindrical sieve surface surrounding the screw. The liquid drains through the sieve surface. The sieve is rotatably mounted to the output port of the tank. The sieve rotates about the screw to move the solids longitudinally towards the discharge end of the screw. A restrictor at the end of the sieve maintains backpressure to squeeze liquid out of the partially dried solids. A housing surrounds the sieve. The housing is mounted to the input port of the tank for communicating liquid that drains from the sieve back to the tank by way of the input port.
