Horizontal spiral centrifuge is separated by centrifugal sedimentation principle extruded suspension to achieve solid-liquid separation equipment. Drum is a cylindrical - conical composite cylinder, both ends bearing on the base , so that the motor pulley driven through high-speed rotation . Helices with spiral blade rotor , supported by bearings at both ends of the drum , the drum rotation passing through the differential to the spiral , because the differential differential role in making the screw speed slower than 1% of the drum speed to 3% , so that the drum and the screw there is a relative movement of the screw conveyor structure constituted . The suspension to be separated to the feed tube through the transfer tube spiral added , the acceleration of the disc by the cloth feed holes are thrown into the drum , this, the suspension is placed in a strong centrifugal force field , the solid phase large mass volume , suffered a large centrifugal force , so that the deposition on the inner wall of the drum , brought out from the screw conveyor to the small discharge port , where the centrifugal force to sediment thrown into the enclosure interior . Be clarified liquid phase through to the big end of the spiral channel flow. Overflows through the overflow hole into the cabinet through the exhaust conduit . Thus, the solid-liquid two -phase suspension be separated .
The test results in the case of an oil field trials by the graph above , the separation of the machine operation is continuous and automatic, so horizontal spiral centrifuge separation effect and ease of operation are superior plate and frame pressure filter machine and filter belt filter press , is currently more advanced solid-liquid separation device .
