SCREW PRESS TYPE FILTERING MACHINE

摘要

PURPOSE: A screw press type filtering machine is provided in which the material to be treated is filtered as a material to be treated that is supplied from one end of the screw is being carried to the other end side of the screw by rotating a screw formed in an almost cylindrical shape and inserted into the filtering bodies. CONSTITUTION: The screw press type filtering machine is characterized in that a screw is rotationally inserted into the inner circumference of filtering bodies(10A,10B) formed in an almost cylindrical shape, the material to be treated is filtered by the filtering bodies as a material to be treated supplied from one end side of the screw to the filtering bodies is being carried to the other end side of the screw by rotation of the screw(4), a plural filtering bodies are arranged in a direction of rotation shaft line (O) of the screw, and a filtering part on which filtering gap is formed to filter the material to be treated is installed on the circumferential part of the body of the filtering bodies, wherein the filtering part is formed in such a way that a plurality of wedge wires are coiled on the circumferential part of the body of the filtering bodies so that the wedge wires are arranged in a row with the filtering gap being formed in a central shaft direction of the filtering bodies.
