1, Summarize
Hydrocyclone sink sand pool is using machine force control flow regime and flow velocity and acceleration of precipitation and make organic sand with flow in the sand away sink devices.
2, Structure, principle
Heavy sand pool flow inlet, flow by exports, heavy sand area, sand measures, turbine driving devices and flushing system, etc. Sewage into the mouth of tangent to sink into the sand area, water channel set a plunge, made possible deposition in the weir channel sand into the bottom of the sink down sand pool; Also has a baffle, make water flow and sand into the sink to the bottom sand pool, and strengthen the popular with wall effect. In the heavy sand pool with adjustable among the paddle board, make in the pool of water keep circulation. Paddle board, baffle water inflow together, the rotation of the sand turbine blade is spiral flow, promote the separation of organic matter and sand, because by centrifugal force, the relative density of different large sand to the wall, sling back by gravity sank into the sand scuttle; And the lighter organic matter, the sand pool in the middle part of sink with sand separation, organic matter with rotation flow out of the pool of water outside. By adjusting the rotational speed, can achieve the best of heavy sand effect. A sand in the sand can sink ascent, and air pump means such as sand flushing out, again by sand water to clean the standard of separation flushing.
3, Characteristics
To adapt to the change of discharge ability.
Head loss is small, the typical loss value only 6 mm.
Fine sand removal rate is high, 140 (0.104 mm) purpose fine sand also can be amounted to 73%.
Kinetic energy efficiency.
