Technical Field

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

[0002] The spiral sand-water separator can be used as a supporting device for various grit chambers to separate sand and other granular solid substances with relatively large specific gravity in sand-containing sewage. The sand-containing sewage tangentially enters from the upper end of the conical container. A vortex is formed in the container. Under the action of gravity and centrifugal force, the sand grains quickly settle to the bottom of the container and are pushed to the upper sand discharge port by the rotating spiral blades for discharge.

[0003] In the prior art, the patent document with the publication number of CN215691864U discloses a spiral sand-water separator, including: a water tank, a U-shaped conveying trough, a shaftless spiral blade and a driving device; the U-shaped conveying trough is inclined with the left end lower and the right end higher; the shaftless spiral blade is arranged in the U-shaped conveying trough, the lower section thereof is located in the water tank, and the upper end is connected to the driving device; a concentric column is arranged inside the shaftless spiral blade, and the diameter of the inscribed cylinder of the shaftless spiral blade is larger than the diameter of the concentric column.

[0004] During the use process, it is found that when the sand water passes through the water tank of the above device, if the water flow rate is relatively fast, some of the sand grains in the sand water have not settled and are discharged together with the water, and the sand-water separation effect needs to be further improved.
