Peripheral drive mud scraper is a sedimentation tank mud scraper commonly used in urban water plants and urban sewage treatment plants. Adopt intermediate water inlet, mud discharge, and peripheral drainage to ensure uniform water flow. Self-priming sludge discharge using liquid level difference, scum scraper collection and removal device and overload protection device. Peripheral drive mud scraper is mainly composed of drive mechanism, main beam, center rotating bearing, deflector, mud scraper system, slag hopper and flushing mechanism, articulated scraper rake, skimming plate, skimming bucket, outlet triangle edge plate, scum baffle, control box and other parts. Structural characteristics of peripheral transmission scraping mud suction machine: 1. The transmission device is optimized and designed, with higher efficiency and more beautiful appearance. It can be equipped with imported reducer or shaft mounted reducer according to user requirements, which is more beautiful and durable. 2. The equipment has large processing capacity and good sludge scraping effect. 3. The equipment has compact structure, small footprint, and convenient operation and maintenance. Peripheral drive mud scraper main performance: pool bottom mud scraper, water surface slag skimming. The drive device adopts shaft mounted gear reduction motor and active roller direct transmission, compact structure, high mechanical efficiency; parallel dislocation line mud scraper, good continuity, high mud collection efficiency.
