Description

Technical Field

[0002] A sewage sedimentation tank is a structure for removing suspended solids in water by sedimentation and a device for purifying water quality. After long-term use of the sewage sedimentation tank, it is necessary to discharge the sludge deposited at the bottom. Some sludge discharging devices for sewage sedimentation tanks include a sludge suction pump. The inlet of the sludge suction pump is connected with a sludge suction pipe. The sludge suction pipe is of an L-shaped structure, and the vertical end faces downward. A circular ring is fixedly arranged on the vertical side wall of the sludge suction pipe. A plurality of electric telescopic rods are uniformly arranged along the circumferential direction below the circular ring. A second circular ring sleeved outside the sludge suction pipe is arranged between the lower ends of the electric telescopic rods. A plurality of motors are uniformly arranged along the circumferential direction above the second circular ring. The output end of the motor faces downward and passes through the second circular ring and is connected with a rotating rod. A plurality of stirring blades are uniformly arranged along the circumferential direction on the side wall of the rotating rod at the lower end of the sludge suction pipe. When the sludge suction pump of the device sucks sludge, the stirring blades are driven by the motor to rotate, so that the sludge that has not been sucked into the sludge suction pipe can be broken up and then sucked into the sludge suction pipe, thereby avoiding the blockage of the sludge suction pipe. However, this device uses a plurality of motors, resulting in a high production cost.
