Truss structure and use effect of scraper

When the scraper is in use, its driving device drives the scraper to rotate around the center of the sedimentation tank. After the raw water is precipitated by the sedimentation tank, the supernatant is discharged from the overflow weir, and the sludge deposited at the bottom of the tank is in a logarithmic spiral curve. Under the push of the squeegee, slowly flow along the bottom of the pool to the central mud collecting tank and discharge through the drain pipe. At the same time, the scum of the pool surface is concentrated to the area between the scum scraper and the scum baffle. When the working bridge passes through the scum discharge cylinder floating on the pool surface, the scum discharge cylinder is pressed under the liquid surface, and the scum passes. The discharge cylinder is discharged outside the pool.

Scraper use characteristics

1. The scraper is mainly in the form of logarithmic spiral curve. It uses a rubber wheel support to walk along the bottom of the pool to a certain extent. The scraping effect is good, the requirements on the bottom of the pool are low, and the adaptability is good.

2. In addition to the main scraping device, a unique auxiliary scraping device is installed to enable the half-bridge scraper to function as a full-bridge scraper;

3. The working bridge adopts truss structure, and the steel grating is laid on the bridge deck, which has high strength, light weight and low energy consumption;

4. The driving wheel is a solid rubber wheel, no track is required, the structure is simple, and the installation is convenient;

5. The underwater parts are made of stainless steel. The water parts are made of carbon steel and hot dip galvanized. It has good corrosion resistance and long service
