Some common sense about spiral sand and water separators
Release time:
2022-11-07
The spiral sand-water separator can be used as auxiliary equipment for various sedimentation tanks to separate sand and other heavier granular solids from sand-containing wastewater. Sand-containing wastewater enters tangentially from the upper end of the conical container. A vortex is formed in the container. Under the action of gravity and centrifugal force, the sand quickly settles to the bottom of the container and is pushed to the sand outlet at the upper end by the rotating spiral blade. The vortex generated by the special water inlet method greatly accelerates the sedimentation speed of the sand. Compared with ordinary sand-water separators, the sedimentation speed of sand is faster, and the sand-water separation effect is better. Through experiments, the separation effect of sand particles with a diameter greater than 0.2 mm is as high as 90%. The characteristics of the spiral sand-water separator are as follows: 1. The sedimentation device and sand conveying device of the sand-water separator are an enclosed integrated structure, which is characterized by compact structure, light weight, high operational reliability, and small maintenance workload. 2. The separation efficiency of the spiral sand-water separator can reach 96%~98%, and particles with a particle size of 0.2 mm can be separated, with a recovery rate of no less than 98%; the recovery rate of gravel with a diameter greater than 0.1 mm is no less than 80%. 3. Under normal circumstances, the sand-water separator matches the performance of the pump-type sand remover and the sand pump in the sand storage chamber. If necessary, it can also operate continuously. 4. Spiral sand-water separator

Characteristics of spiral sand and water separator;
1. The sedimentation device and sand conveying device of the sand and water separator are integrated in a closed structure, which is characterized by compact structure, light weight, high operational reliability, and small maintenance workload.
2. The separation efficiency of the spiral sand and water separator can reach 96%~98%, and can separate particles with a diameter of 0.2mm, with a recovery rate of not less than 98%; the recovery rate of gravel with a diameter greater than 0.1mm is not less than 80%.
3. Under normal circumstances, the sand and water separator matches the performance of the pump-type sand separator and the sand pump in the sand storage chamber. If necessary, it can also operate continuously.
4.Spiral sand and water separatorThe shell, bracket, sand conveyor and other important components are made of stainless steel. The conveying screw in the U-shaped groove is an axelless screw. Its structural design ensures that the material circulation is not blocked; the axelless spiral body has sufficient strength and rigidity to ensure that it will not deform or stretch under the maximum working load.
5. The waterproof, dustproof, wear-resistant and self-lubricating bearing of the axelless spiral.
6. The separation tank of the spiral sand and water separator is welded from stainless steel, and the bottom is semi-circular to support the screw conveyor. The water inlet overflow pipe is installed at the top of the container, and the drain pipe is installed at the bottom for easy maintenance. All pipe fittings and flanges are made of stainless steel.
7. The diameter of the inlet and outlet pipes of the spiral sand and water separator is designed to prevent blockage of sundries in the water.
8. The configuration of the desander and auxiliary components is suitable for continuous and intermittent operation.
9. A sufficient number of replaceable liners are installed in the spiral groove of the U-shaped groove, with simple structure, long service life, and easy replacement.
10. There are no high-speed rotating parts in the equipment, so the screw wear is low and almost no maintenance is required.
11. The drive device adopts a shaft-mounted reducer, and the output shaft is directly connected to the screw. Output directly connected to the screw: the protection level of the drive motor is IP55, and the insulation level is F.
12.Spiral sand and water separatorThe sedimentation device and sand conveying device are integrated in a closed structure, which is characterized by compact structure, light weight, high operational reliability, and small maintenance workload.
