ABSTRACT:
A rotary strainer comprising a revolving box-like structure having a horizontal axis of revolution and a filtering net stretched around the external periphery of said box-like structure, wherein a mixture of liquid and solids is introduced into said box-like structure so as to primarily separate said solids and liquid by said filtering net, with the thus separated solids being dropped with rotation of said box-like structure onto a screw conveyor extending through the inside of said structure so as to discharge the separated solids out of the structure by said conveyor, and the bottom face of a screw conveyor chute provided below the screw is slanted downwardly toward the box-like structure so that the liquid adhering to the primarily separated solids will flow back toward said box-like structure by dint of said slant for further separation.
