AI Technical Summary
When existing spiral sand-water separators deal with water-sand mixtures containing large stones, they are prone to problems such as poor material flow and equipment blockage, which affects normal operation.
A spiral sand and water separator is designed, which includes a filter separation box and a crushing grille. After the water and sand mixture enters the filter separation box, the clusters of sand and stones are broken on the blade of the crushing grille to prevent the stone from jamming the equipment.
It effectively avoids blocking the spiral conveying device by stones, prevents equipment from being blocked, and ensures the normal operation of water and sand separation.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of sand-water separators, in particular to a spiral sand-water separator. Background Art
[0002] The sand-water mixture enters the water tank from the top of one end of the separator. The particles with larger specific gravity (such as sand) in the mixture fall due to their own weight and settle at the bottom of the trough. Under the push of the spiral blades, the sand is lifted along the bottom of the inclined U-shaped trough. After leaving the liquid surface, the sand will continue to move up for a distance. In this process, the water in the sand gradually flows back to the water tank through the gaps of the spiral groove blades, making the sand further dry. Finally, the sand falls into other conveying devices by its own weight, while the supernatant continuously overflows from the drainage weir, thus achieving the purpose of sand-water separation.
[0003] For example, the spiral sand-water separator is composed of a shaftless spiral, lining strips, U-shaped grooves, a water tank, a guide plate, a water outlet weir and a driving device. The sand-containing sewage enters tangentially from the upper end of the conical container, forming a vortex in the container. Under the action of gravity and centrifugal force, the sand particles quickly settle to the bottom of the container and are pushed to the sand outlet at the upper end by the rotating spiral blades for discharge.
[0004] Large stones are large in size and may get stuck in the hopper, conveying channel or separation components, causing poor material flow. In severe cases, the entire equipment will be blocked, affecting normal operation. For example, stones may get stuck between the spiral blades and the U-shaped groove, hindering the rotation of the spiral and preventing the sand and water mixture from being transported and separated normally.
