Swirling sand catcher is a kind of Swirling desander systems, include swirling sediment sand tank, impeller, rotating shaft, motor, reducer and ,grit classifier( screw sand and water separators) ,sand suction system( Root blowers or suction sand pumps).
Grit classifier(screw sand and water separator) includes :the shaftless screw , lining, U-shaped tank, water tank, baffle, water weir and drive .
The impeller rotation will make the sewage water in the spiral movement, coupled with the sewage tangential into the flash generated in line with the swirling tank, the sewage water forms a vortex flow, in the appropriate leaf pulp angle and linear velocity conditions , The sand in the effluent will be washed and still maintain the best sagging effect, and the original attached to the sand on the organic matter and the weight of the material with the sewage out of the swirling tank. The swirling sand catcher r is an advanced sand removal system ,sagging, sand washing effect is good, widely used in urban hotels, factories and mines enterprises and cities widely , medium and small sewage treatment works in the pre-treatment process.
1, compact structure, small footprint, less equipment investment;
2, reasonable structure, low maintenance rate, energy consumption, operation and management and easy maintenance;
3, the equipment corrosion resistance, long service life;
4, flexible and convenient layout, easy to match the combination to meet the needs of different periods of construction projects;
5, griting effect is good, remove the water in the inorganic gravel is particularly significant;
6, a high degree of automation, can be used in a variety of ways to control, but also with other unified control of the same process equipment
