Purpose:

The function of LS type spiral sand water separator is to separate the sand water mixture discharged from the sedimentation tank of the sewage treatment plant.

Structural principle：

The LS type spiral sand water separator consists of a shaftless spiral body, a water tank, a U-shaped groove, and a transmission device. Usually linked with sand removal equipment.

The sand water mixture from the sand removal tank enters the water tank from the top of one end. The high-density particles in the mixture deposit at the bottom of the U-shaped groove. The transmission device drives the spiral mechanism to rotate. Under the push of the spiral mechanism, the sand particles gradually move upward along the U-shaped groove bottom at a certain inclination angle and leave the water surface. To fully dehydrate, the sand particles continue to move upward until they are discharged from the sand outlet to the sand storage hopper. The water separated from the sand particles is discharged from the overflow outlet.

characteristic：

1. The separation efficiency is over 98%, and particles with a diameter of ≥ 0.2mm can be separated;

2. Adopting shaft mounted reducer and shaftless spiral, without water bearing, simple structure, easy installation and maintenance;

3. The lining strip is made of flexible wear-resistant material, with low noise and easy replacement;

4. Specially designed inlet and overflow trough to minimize turbulence and improve sand collection rate.
