The service bridge is arranged at top of the sewage barrel, the sewage barrel is arranged on the support, a loop of the overflow weirs are arranged at the surrounding of the sewage barrel, a center bearer is arranged at the center of the service bridge, the main driving motor and the speed reducer are fixed on the center bearer, the flocculation mixers are respectively arranged at two sides of the center bearer, a stirring device is connected with the lower end of the flocculation mixer, a water inlet pipeline is arranged between the service bridge and the sewage barrel, an outlet of the water inlet pipeline is placed in the flocculation barrel, an outlet of the overflow weir is arranged at the upper part of the side wall of the sewage barrel, an output shaft of the motor is connected with the speed reducer, a base plate of the sewage barrel is the tapered base plate, a downwardly recessed mud collecting cavity is arranged at a top angle position of the tapered base plate, the mud collecting cavity is the tapered cavity, the scraper plate employs an arc-shaped structure, and an anticorrosion coating layer is arranged on the scraper plate.

Description

technical field [0001] The invention relates to the field of sewage treatment equipment, in particular to an arc-shaped scraper centrally driven mud scraper. Background technique [0002] The mud scraper is a kind of mud discharge equipment, which is used in circular sedimentation tanks with large diameters in urban sewage treatment plants, waterworks and industrial wastewater treatment to remove the sludge settled at the bottom of the tank and skim the scum on the surface of the tank . Its working principle is that the driving device drives the mud scraper to rotate around the center of the sedimentation tank. After the raw water is settled in the sedimentation tank, the supernatant is discharged from the overflow weir plate, and the sludge settled at the bottom of the tank is slowly removed by the scraper. The soil flows along the bottom of the pool to the central mud collecting tank and is discharged through the mud discharge pipe. At the same time, the scum on the pool...
