Product Description

1. Introduction
Central drive sludge scraper mainly suits for circular radial flow sedimentation tank of sewage treatment plant. Its major function is to scrape the settling sludge to the sludge tank in order to sludge back-flow and sludge thickening and dewatering. Depending upon circumstances, we can also set up a skimming mechanism on the water surface, collecting the float scum discharged by hopper. 
 ZG sludge scraper mainly apply for the settling tank whose diameter is no more than 20m. It consists of working bridge, drive mechanism, drive shaft, scraping arm and scum board, dragline, underwater bearing, agitating impeller, steady flow cylinder and electric cabinet. According to the actual condition, we can add effluent weir plate, skimming mechanism, slag tap and sludge hopper,etc.
 When the ZG sludge scrapper working and running, its drive mechanism installed on the working bridge will drive up the transmission shaft for rotary. When the transmission shaft rotates, it will let the scraping arms on two sides rotate around the tank central axis. One set of scum board will rotate together with scraping arm, finally scraping out the settling sludge from the tank bottom to the sludge collecting tank. At the same time, if there is float scum, the skimmer will scrape it into sludge hopper.
2. Features
