Overview: spiral sand water separator is suitable for grit chamber of sewage treatment plant, and it is the equipment used for sand water mixture in sewage treatment. working principle: Sand water separator equipment generally has a helix angle of 25-30 °. The sand water mixture enters the equipment from the water inlet pipe. The mixture passes through the collecting box at the upper part of the separator. Under the action of the water flow, the sand particles of the mixture are separated from the organic matters. The sand water enters the sand collecting tank. The particles with larger proportion (such as sand particles) fall due to their own weight and are deposited at the bottom of the helix tank. In the helix blade Under the push of, the material is lifted along the bottom of the inclined U-shaped groove. After leaving the liquid level, it continues to move upward for a certain distance. The water in the sand gradually flows back to the water tank in the gap of the spiral groove blade, and the sand liquid gradually dries to the outlet. It falls into other conveying devices by its own weight. The supernatant continuously overflows from the drainage weir. Under the action of the current vortex, the organic matters also follow the supernatant The liquid flows out from the overflow tank and flows back to the sewage well, so as to achieve the role of sand water separation. Outline diagram:
Technical performance and features: the separation efficiency can reach 96-98%, and particles with particle size ≥ 0.2mm can be separated; the shaftless screw conveyor is adopted, without bottom bearing, consumables, reasonable structure design, blockage free, and low maintenance cost.
The separation efficiency can reach 96-98%, which can separate particles with the particle size ≥ 0.2mm; it adopts shaftless screw conveyor, no bottom bearing, no consumable, reasonable structure design, no blockage, and low maintenance cost.
