During the operation of the scraper, its driving device rotates around the center of the sedimentation tank. After the raw water is settled in the sedimentation tank, the supernatant is discharged from the overflow weir plate and deposited in the sludge at the bottom of the tank. Driven by the logarithmic spiral scraper, the scraper slowly flows along the bottom of the tank to the central sludge collecting tank and discharges through the sludge discharge pipe. At the same time, the pool surface scum concentrates in the area between the scum scraper and the scum baffle. When the working bridge passes through the scum discharging cylinder floating on the pool surface, the scum discharging cylinder is pressed under the liquid surface, and the scum discharges out of the pool through the discharging cylinder.

Characteristic of mud scraper

1. The scraper adopts logarithmic spiral curve form and rubber wheel support to walk along the bottom of the pond. The scraping effect is good and the requirement for the bottom of the pond is low.

2. In addition to the main mud scraper, a unique auxiliary mud scraper is installed to make the half-bridge mud scraper work as a full-bridge mud scraper.

3. The working bridge adopts truss structure, and the deck is paved with steel grille, which has high strength, light weight and low energy consumption.

4. The driving wheels are solid rubber wheels, which need no track, have simple structure and convenient installation.

5. The underwater parts are made of stainless steel. The underwater parts are made of carbon steel and Hot-Dipped galvanized. It has good corrosion resistance and long service life. www.khnwatertreatment.com
