Abstract

The invention relates to a grit-water separator which comprises a water tank and a spiral conveyor, wherein the water tank is upward inclined arranged; the spiral conveyor is arranged in the water tank; a water inlet is formed in the upper end of the water tank; an overflow launder is arranged at the near top end of the water tank; a downward bent overflow pipeline is arranged in the overflow launder; the spiral conveyor comprises a U-shaped groove with an opening at the top end; an axle-less helical blade is arranged in the U-shaped groove; an output shaft is arranged at the top end of the helical blade; the output shaft is connected with a driving device; one end of the U-shaped groove is inserted into the water tank while the other end extends out of the water tank and is provided with a downward vertical unloading port; the inclined angle of the U-shaped groove is identical to the inclined angle of the bottom surface of the water tank; a rubber plate is arranged at the bottom of the water tank and the bottom of the U-shaped groove; the thickness of the rubber plate is 15mm-20mm; a wear-proof sleeve with curvature identical to the curvature of the helical blade is sleeved on the external end face of the helical blade. The grit-water separator has the advantages of reasonable structure, effective shock prevention, low wearing degree of helical blade and high grit-water separating efficiency.

Description

technical field [0001] The invention relates to a sand-water separator, in particular to a spiral sand-water separator. Background technique [0002] The spiral sand-water separator is suitable for the grit chamber of the sewage treatment plant. It is an integrated equipment for the separation and lifting of organic sand in sewage. It can separate particles with a particle size of ≥0.2mm and has a high separation efficiency. The equipment adopts No shaft screw, no water bearing, light weight, compact structure, reliable operation, easy installation, etc., it is an ideal sand-water separation equipment. In the prior art, the screw conveyor of the sand-water separator does not closely cooperate with the water storage tank, and the vibration is relatively large, resulting in relatively large noise and unstable operation of the equipment. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention provides a sand-water separator with reasonab...
