Description

Technical Field

[0002] Cyclone sand settling machines are often used in sewage pretreatment. The sewage is driven to rotate by a propeller, and the particles in the sewage and the impurities with small mass on the surface of the sand are separated by the combined action of gravity and centrifugal force, so that the particles and sand sink to the bottom, and the light impurities in the sewage float on the top of the sewage to achieve the purpose of separation. However, the existing sand settling machines usually use manually controlled valves to discharge sewage in the pipeline for removing floating objects on the top, and the excessive content of particles and sand in the sewage is easy to accumulate at the bottom of the sand settling machine, resulting in poor sand discharge, which may seriously cause blockage.
