purpose

Used in the sedimentation tank of sewage treatment plants to separate the sand and water mixture discharged from the sedimentation tank.

characteristic

This product has been improved and designed based on the usage of this type of product both domestically and internationally. It solves the problems of inconvenient replacement of lining strips and non adjustable screw axial position. Its characteristics are as follows:

The separation efficiency can reach 96%~98%, and particles with a diameter of ≥ 0.2mm can be separated;

2. Adopting shaftless spiral and waterless bearings for easy maintenance;

3. Compact structure and light weight;

The key component of the new transmission device, the reducer, is an advanced shaft mounted type that does not require a coupling and is easy to install and align;

The 5 lining strips are quick to install and easy to replace;

The axial position of the 6-helix is adjustable, making it easy to adjust the safety clearance between its tail and the box wall.

Construction and working process

The spiral sand water separator consists of a shaftless spiral, a lining strip, a U-shaped groove, a water tank, a guide plate, an outlet weir, and a driving device.

The sand water mixture is input into the water tank from the top of one end of the separator. The heavier components in the mixture, such as sand particles, will deposit at the bottom of the groove. Under the push of the spiral, the sand particles will rise along the inclined groove bottom and continue to move a certain distance away from the liquid surface. After the sand particles are fully dehydrated, they will be discharged into the sand bucket through the sand discharge port. The water separated from the sand water will be discharged from the overflow port and sent to the inlet water tank in the factory.
