[0009] The working principle and beneficial effects of the utility model are:

[0010] When the present application is applied, the central control module controls the mud in the concentrator to be introduced into the metering container during operation. After sending the mud collection instruction, the data acquisition module receives the signals of the weighing sensor and the infrared ranging sensor. On the one hand, the weighing sensor collects the mass of the mud in the metering container, and on the other hand, the infrared ranging sensor collects the liquid level of the mud. At the same time, the collected data is input into the central control module through the data acquisition module. After the central control module obtains the data threshold, it controls to stop collecting. Similarly, when the collected weight or height reaches a certain level, the alarm system is activated to monitor the amount of mud introduced through images. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Operation Mode:

[0018] Normally, the moisture content of the sludge discharged from the sludge thickener is in the range of 95-96%, corresponding to a sludge density of 1.025-1.031, while the abnormal moisture content of the sludge discharged is in the range of 98-99%, corresponding to a sludge density of 1.00-1.01. As shown in the figure below, the alarm value is set according to the requirement of the moisture content of the sludge discharged. The weighing system is located at the sludge outlet of the thickener. The weighing feedback is given at a fixed volume interval. If it exceeds the range, an alarm is issued to indicate abnormal operation.

[0019] At the same time, a surveillance camera is installed on the side of the concentrator filtrate. When an alarm is triggered, it will prompt the central control personnel of the abnormality and observe the clarity of the filtrate. If it is turbid, it is determined that the system is abnormal and needs to be checked on site. If the filtrate is clear, continue to observe and make a judgment based on the experience of the on-site personnel.
