Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water conservancy projects, in particular to a cyclone sedimentation device for water conservancy projects. Background Art
[0002] Cyclone grit setters are widely used in the field of sewage treatment. When the cyclone grit setter is working, when the water flows into the equipment tangentially from the sand removal inlet under a certain pressure, a strong rotational motion is generated. Due to the different densities of sand and water, under the combined action of centrifugal force, centripetal force, buoyancy and fluid drag, the water with low density rises and is discharged from the outlet, and the sand with high density is discharged from the sewage outlet at the bottom of the equipment, thereby achieving the purpose of sand removal.
[0003] When the existing cyclone sand settling tank discharges silt through the sand discharge tank, a large amount of impurities and sediment will be generated on the inner wall of the cyclone sand settling tank. If the impurities and sediment are not removed for a long time, they will be adsorbed on the inner wall, so that the impurities and sediment will form lumps together, thereby reducing the sand discharge rate and affecting the ease of use and applicability. Because the sediment has a certain degree of adhesion, long-term use will cause the sediment to adhere to the inner wall surface of the cyclone sand settling device, affecting normal use.
[0004] Some cyclone desilting devices separate the water and sediment in sewage. Due to the different centrifugal forces, the sand particles with larger relative density are thrown to the wall of the pool and sink into the sand hopper under the action of gravity; while the lighter organic matter is separated from the sand in the middle part of the desilting tank. However, after the existing cyclone desilting devices for water conservancy projects separate the water and sand particles, the sand and gravel are easy to stick together into blocks, which is not convenient for subsequent use. The separated sand and gravel contains water and is not convenient for transportation. Utility Model Content
