The filter tube 402 is screwed to the connecting tube 401 through a thread, and a second filter hole is opened on the filter tube 402. By setting a stirring device 4, the gear 403 is used to drive the push block 405 and the spiral conveying plate 404 in the connecting tube 401 to rotate, so as to rotate and push the block objects in the wastewater. The wastewater can enter the filter tube 402 through the first filter hole 407 on the connecting tube 401, and then be swung by centrifugal force in the L-shaped filter tube 402. The whole can make the solid-liquid separation more complete, and the filter tube 402 is also easy to disassemble and clean later.
