As an important part of trenchless technology, screw extrusion dredging equipment is more and more widely used. The screw sand-water separator is a device for preliminary screw extrusion separation of the sewage pumped out of the pipeline. Its working principle is mainly to separate the sand-water mixture by using the centrifugal force field or the pushing action of the screw blade. When the sand-water mixture enters the separator, due to the larger specific gravity of solid particles such as sand grains, they will deposit at the bottom of the trough-shaped bottom under the action of gravity or centrifugal force. Subsequently, under the pushing of the screw blade, the sand grains are lifted along the inclined bottom of the trough, continue to be pushed for a certain distance after leaving the liquid surface, and are discharged through the sand discharge port after the sand grains are fully dewatered. The water separated from the sand grains is discharged from the overflow port, realizing the effective separation of sand and water.
