Use of scraper
Mud scraper is mainly used in municipal sewage treatment plants, waterworks and industrial wastewater treatment in the larger diameter circular sedimentation tank, the sedimentation in the bottom of the pool to exclude the sludge and scum to remove the pool surface.

working principle
The driving device drives the scraper to rotate around the center of the sedimentation basin. After the raw water is precipitated in the sedimentation basin, the supernatant is discharged from the overflow weir and is deposited on the bottom of the pool. Under the impetus of the logarithmic spiral curving blade, The flow goes to the central sump along the bottom and discharges through the sluice. At the same time pool surface dross concentrated to the area between the scum and the scum baffle, when the working bridge through the scum on the surface of the discharge tank, the scum discharge cylinder is pressed to the surface, scum through Exhaust cylinder discharge tank.

Mud scraper features
1, scraper with logarithmic spiral curve, and the use of rubber tire support walking along the bottom of the pool, scraping mud effect, the bottom of the lower requirements,
Good adaptability;
2, In addition to the main scraper device, but also install a unique auxiliary scraper device, so that half-bridge scraper can play the full bridge scraper effect;
3, the working bridge truss structure, the deck laying of steel grating, high strength, light weight, energy saving;
4, driving wheel is a solid rubber wheel, no track, simple structure, easy installation;
5, underwater parts are made of stainless steel, water parts using carbon steel and hot dip galvanized, corrosion resistance, long service life.
