The use
of sand water separator is suitable for the grit treatment of grit tank of urban sewage treatment plant, which is mainly used with swirling grit tank desanding machine or bridge sand suction machine to further separate the discharged sand-water mixture.

Structure and working principle
The equipment adopts shaftless spiral type, the sand-water mixture is input from the upper part of the separator, the gravel is settled by gravity in the sand-water separation tank, and the rotation of the shaftless spiral is used to gradually push the gravel along the 25% U-shaped groove to the outlet, fall into the receiving cylinder and transport out, and the separation water is out from the overflow of the separation tank to improve the operating environment and facilitate external transportation.

Main features
: The drive device adopts shaft-mounted parallel shaft helical gear reducer, which has compact structure and stable and safe operation; The recovery rate of particles with a particle size greater than 0.2mm can reach 96% after separation;
The U-shaped groove is lined with strong wear resistance, long service life and easy replacement; the whole is fully enclosed operation, the environmental conditions are better, and the frame is fixed by expansion bolts without embedded parts
