Efficient sedimentation tank sludge layer monitoring system based on torque transmission

The invention belongs to the technical field of sewage treatment, and discloses an efficient sedimentation tank sludge layer monitoring system based on torque transmission, which comprises a base, a mounting groove is formed in the base, and a torque sensor is fixedly arranged in the mounting groove. The suction conveying assembly is installed, the suction conveying assembly sucks sludge from one end, conveys the sludge into the guide frame at the bottom and discharges the sludge from the other end of the suction conveying assembly, the detection and extraction assembly capable of being adjusted in a lifting mode is additionally arranged in the guide frame, and in the process of guiding and filling the sludge into the guide frame, the detection and extraction efficiency is improved. Part of sludge is rapidly extracted and separated to the outer sides of the sludge tank and the rotating disc by matching with the downwards-moving detection and extraction assembly, the separated sampled sludge is directly taken
