Description

Technical Field

[0001] The utility model relates to the field of sand-water separators, in particular to a spiral sand-water separator. Background Technique

[0002] The spiral sand-water separator is applicable to the grit chamber of a sewage treatment plant. It is an integrated device for the separation and lifting of organic sand in sewage and can separate particles with a particle size ≥ 0.2 mm. It has a high separation efficiency. The device uses a shaftless screw and has no water bearings in water, featuring light weight, compact structure, reliable operation, and convenient installation. It is an ideal sand-water separation device. A spiral sand-water separator with the publication number CN 218709537 U includes a water tank, a water inlet pipe, a pushing component, a support column, a shock absorption component, and a flocculation device. The water inlet pipe is welded to the center of the top end face of the water tank. A pushing component is arranged at one end of the bottom of the water tank. Support columns are welded around the outer wall of one end of the bottom of the water tank, and a shock absorption component is arranged at the bottom end of the support columns. A flocculation device is arranged at the top of the outer wall of one side of the water tank, and a drain pipe is welded below the bottom of the flocculation device. A material guiding pipe is welded to the outer wall of the other side of one end of the bottom of the water tank. A separator body is fixedly installed outside the other side of the water tank.

[0003] In the above technical solution, a filter screen is welded inside the pipeline of the water flowing out of the device. When the device is used for a long time, the filter screen is easily blocked by sand and gravel. Since the filter screen is directly fixed to the device, it is not easy for the user to clean the filter screen. Therefore, we propose a spiral sand-water separator to solve this problem.
