Drive device and truss structure of automatic center drive scraper

In the process of operation, the automatic center drive scraper 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 raft and precipitates at the bottom of the tank. The mud, driven by the logarithmic spiral curved scraper, slowly flows along the bottom of the pool to the central mud collecting tank and is discharged through the draining 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.

The fully automatic center drive scraper is mainly used in the form of logarithmic spiral curve, and uses rubber wheel support to walk along the bottom of the pool. The scraping effect is good and the requirements on the bottom of the tank are low, except for the main scraping device. A unique auxiliary scraper is also installed to enable the half-bridge scraper to function as a full-bridge scraper.

The working bridge of the automatic center drive scraper adopts the truss structure, the bridge deck is laid with steel grid plate, the strength is high, the weight is light, the energy consumption is saved, the driving wheel is a solid rubber wheel, no track is needed, the structure is simple, the installation is convenient, water The lower parts are made of stainless steel, the water parts are made of carbon steel and hot dip galvanized, which has good corrosion resistance and long service life.www.khnwatertreatment.com
