Abstract
An improved screw type apparatus for separating the liquid phase from a solid-liquid mixture includes a conveyor screw and a discharge housing that includes an imperforate cylindrical wall which surrounds the downstream end of the screw tube and has a discharge opening formed therein. A discharge gate is pivotally mounted in the discharge opening, and a pneumatic actuator is provided to bias the gate toward a closed position with a preselected, constant force. Paddles are affixed to the cylindrical downstream end of the screw tube at longitudinal spacings thereon for the purpose of propelling the deliquified solid phase of the mixture about the end of the screw tube, and stripper members are mounted on the interior of the cylindrical discharge housing wall adjacent the discharge opening to extend between the paddles to aid in urging the solid material into the discharge opening.
