SLF spiral sand-water separator is suitable for grit chambers of sewage treatment plants (stations), and is a device used to treat sand-water mixture in sewage treatment.
The sand-water mixture is fed into the water tank from the top of one end of the separator, and the larger specific gravity in the mixture, such as sand particles, will be deposited on the bottom of the trough, driven by the spiral blades. The sand grains are lifted along the bottom of the inclined U-shaped groove, and continue to move for a certain distance after leaving the liquid surface. After the sand grains are fully dehydrated, they are discharged to the sand bucket through the sand discharge port, and the water separated from the sand is discharged from the overflow port to achieve separation. Purpose.
In addition, a cylindrical cyclone pre-separator can also be installed at the water inlet of the sand-water-sand-water separator. The sewage enters the eddy current along the tangential direction of the cylinder to make the sand particles sink into the spiral separator, and the overflow liquid returns to the sand settling tank or grid. The grid well plays the role of pre-sanding and adjusting the water volume. The separation effect of the spiral sand-water separator.

Features
1. The separation efficiency can reach 96-98%, and particles with a particle size of ≥ 0.2 mm can be separated;
2. Adopt shaftless screw, no water bearing, easy maintenance;
3. Compact structure and light weight;
4. The new type of transmission device, its key component - the reducer is an advanced shaft-mounted type, without a coupling, which is convenient for installation and alignment;
5. The lining is quick-installed, which is easy to replace;
6. The axial position of the screw can be adjusted, which is convenient to adjust the safety clearance between the tail end and the box wall.
