Spiral sand water separator is suitable for the sewage treatment plant of grit chamber, is the organic sewage sand separation and to promote the integration of equipment, can separate the grain size of 0.2 mm or more particles, has a high separation efficiency, equipment used shaftless screw, no water bearing, with light weight, compact structure, reliable operation, installation is convenient wait for a characteristic, is an ideal sand water separation equipment.

Spiral sand water separator installation Angle between 20 ° to 30 °, sand and water mixture from the feed line into the water tank, the mixture proportion of larger particles (such as sand) due to gravity drop deposited on the bottom of the spiral groove, under the impetus of the screw, the material at the bottom of the u-shaped groove along the diagonal to ascend, after leaving the liquid level, continue to move a distance, sand water gradually in the spiral groove of the clearance flow back into the water tank, sand also gradually drying at discharging port, relying on gravity fall into other conveyer. The supernatant continues to flow out of the drain. To achieve the purpose of sand - water separation.

1. Spiral-type sand water separator is composed of non-axial screw, liner strip, u-shaped slot, water tank, guide plate, outlet weir and drive device.

2, sand and water mixture from separator at the top of the input water tank, mixture relation between the larger, such as sand will deposit on the groove bottom, the screw, driven by the sand along the inclined groove bottom rises, continue to after leaving the liquid level goes on a distance, the sand discharge to fully dehydration after the row of sand sand bucket, sand and water after separation of water from the overflow mouth out and taken to a factory into the pool.
 

1. The separation efficiency can reach 96% to 98%, and the particles with a particle size of 0.2mm or greater can be separated;

2. Adopt non-axial screw, non-water bearing, easy maintenance; 3. Compact structure and light weight;

4. The new transmission device, whose key production component -- reducer is an advanced shaft mounting type, which is convenient to install without coupling;

5. The liner is quick-loaded and easy to replace.

6. The axial position of the screw is adjustable to facilitate the adjustment of the safe clearance between its tail and box wall;
