What Is a Sand Separator?

Sand water filter is also called sand water separator, spiral sand water separator, rotary filter, spiral separator, shaft sand water separator, shaft sand water separator, spiral sand water separator, etc.

Sand water filter

Sand water filter is an integrated device for the separation and promotion of organic sand in sewage. It can separate particles with a diameter of 0.2mm and has a high separation efficiency. The device uses a shaftless screw and no water bearing. Compact structure, reliable operation, easy installation, etc. It is an ideal sand-water separation equipment.

The installation angle of the sand water filter is between 20 ° -30 °. The sand-water mixed liquid enters the water tank from the water inlet pipe. The particles (such as sand particles) with a larger specific gravity in the mixed liquid are deposited on the bottom of the spiral groove due to the drop of the weight surface. Under the push, the material is lifted along the bottom of the inclined U-shaped groove. After leaving the liquid surface, it continues to move up a distance. The water in the sand gradually flows back to the water tank in the gap in the spiral groove, and the sand gradually dries at the discharge port. , Rely on its own weight to fall into other conveying devices. The supernatant was continuously flowing from the drain. To achieve the purpose of sand and water separation.

Structure and working process of sand water filter:

1. Spiral sand-water separator consists of shaftless spiral, lining strip, U-shaped groove, water tank, deflector, outlet weir and driving device.

2. The sand-water mixture enters the water tank from the top of one end of the separator, and the heavy liquid is heavy. For example, sand particles will be deposited at the bottom of the groove. Under the spiral drive, the sand particles will rise along the inclined groove bottom and leave the liquid surface. Continue to move for a distance, after the sand is fully dehydrated, it is discharged to the sand bucket through the sand discharge port, and the water separated from the sand water is discharged from the overflow port and sent to the plant into the pond.

Sand water filter characteristics and uses:

The sand-water separator is suitable for the sand settling tank of a sewage treatment plant, and the sand-water mixed liquid discharged from the sedimentation tank is used for sand-water separation. ^[1]

1. The separation efficiency can reach 96% ~ 98%, and particles with a particle size 0.2mm can be separated;

2. Adopt shaftless spiral, no water bearing, easy maintenance;

3. Compact structure and light weight;

4. The new transmission device, the key product of which is the reducer is an advanced shaft-mounted type, without a coupling, which is easy to install and align;

5. The lining strip is quick-installed and easy to replace;

6.The axial position of the screw is adjustable, which is convenient to adjust the safety clearance between the tail and the box wall;
