SLF type spiral sand water separator

The spiral sand water separator is a mechanical equipment used for separating the sand water mixture discharged from the sedimentation tank in the first stage sewage treatment process. It can remove impurities such as sand, stones, and inorganic substances. It is an ideal supporting equipment for bell shaped sand settling tanks, aerated sand settling tanks, etc. The sand water mixture enters the storage tank through the flange connection at the top, and the specially designed water dispersing tray inside the tank collects the water in the drainage tank; In the sand water mixture, sand and gravel gradually settle in the spiral U-shaped groove at the bottom, and the hollow spiral slowly rotates to push the gravel towards the upper outlet, naturally dehydrating and removing it. The installation angle of the spiral sand water separator is 20 ° - 30° Between them, the sand water mixture enters the water tank through the inlet pipe. The particles with higher specific gravity (such as sand particles) in the mixture settle at the bottom of the spiral groove due to their own weight. Under the push of the spiral, the material is lifted away from the liquid surface along the inclined U-shaped groove bottom and continues to move up a certain distance. The water in the sand particles gradually flows back to the water tank through the gaps in the spiral groove, and the sand particles also gradually dry at the discharge port, relying on their own weight to fall into other conveying devices. The supernatant continuously flows out from the drainage pipe. Achieve the goal of sand water separation.
