Periphery driving sludge scraper is used in radial flow primary or secondary sedimentation tank of sewage treatment plant. Its main function is to scrape the sludge which is deposited at the bottom of the tank to the sludge collecting pit. Then the sludge will be discharged by sludge discharging pipe, making it convenient for the sludge to return or be thickend and dewatered. If needed, tank surface scraping mechanism can be set to collect the scum on the surface and discharge the scum through the scum hopper.
Working bridge adopts truss structure. It’s simple, aesthetic and lightweight；The driving reducer is of a variety of choices. It can adopt the mounted shaft, which is of simple and compact structure and convenient maintence. It also can adopt the cycloid pin wheel reducer, which is attractive in price and quality and the transmission efficiency is high；
According to the user's needs, the surface material of the walking wheel can be choosed from engineering rubber wheel (standard configuration), steel wheel, nylon wheel, polyurethane wheel；The logarithmic spiral line scraper with high effiency can ensure the reliability of the sludge scraping；Electrical components are of outdoor types, which is safe and reliable and it can be controlled remotely or on the equipment.
