sand-water separator

1、 Structural characteristics

sand-water separatorIt is an integrated equipment for separating and lifting organic sand in sewage, which can separate particles with a particle size of ≥ 0.2mm and has high separation efficiency. The equipment adopts shaftless spiral and water free bearings, and has the characteristics of light weight, compact structure, reliable operation, and easy installation. It is an ideal sand water separation equipment.

2、 Working principle

sand-water separatorThe installation angle is between 20 ° and 30 °. The sand water mixture enters the water tank through the inlet pipe. The particles with a higher specific gravity (such as sand particles) in the mixture settle at the bottom of the spiral groove due to their own weight. Under the push of the spiral, the material is lifted along the inclined U-shaped groove bottom, and after leaving the liquid surface, it continues to move upward for a distance. The water in the sand particles gradually flows back to the water tank through the gap in the spiral groove, and the sand particles gradually dry at the discharge outlet. They fall into other conveying devices by their own weight, and the supernatant continuously flows out of the drainage pipe to achieve the purpose of sand water separation.

3、 Product Features

The sand water separator is suitable for the sedimentation tank of sewage treatment plants, which separates the sand water mixture discharged from the sedimentation tank.

1. 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;

4. 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;

5. The lining strip is of quick installation type, easy to replace;

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

4、 Workflow

1. 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.

2. 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 spiral pushing, 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.
