The hydraulic desilter has a mud cyclone desander , which first pumps the mud into a funnel container by a sand pump. The pumping direction is directed along the tangential line to the inner wall of the container. The slurry is rotated by centrifugation, the structure is destroyed, the cuttings and sand are discharged from the funnel, and the mud flows out from the upper opening of the container. The mud cyclone desander has better sand removal effect than the vibrating screen and is widely used in deep well drilling. hydro-cyclones The cyclone desander is based on the principle of centrifugal sedimentation and density difference. When the water flows from the sand removal inlet to the equipment in a tangential direction under a certain pressure, a strong rotary motion is generated. Due to the different density of sand and water, the centrifugal force, Under the combined action of centripetal force, buoyancy and fluid drag, the low-density water is lifted and discharged fro
