Background
Coal is the main energy in China, and accounts for more than 70% of primary energy consumption; the position of coal as a primary energy source does not change over a considerable period of time. Due to the geological structure and the mining mode, a large amount of gangue is inevitably mixed after the coal is mined, the part of gangue has high ash content, high sulfur content and low heat productivity, and causes great adverse effect on the clean utilization of the coal, and the main solution adopted at present is coal separation. The traditional coal separation method is mainly wet separation, and the coal separation method is divided into desliming and desliming according to whether desliming is carried out before separation. No matter which way is adopted, the treatment of the slime water of the coal preparation plant is a great problem in the production of the coal preparation plant and even becomes an obstacle for restricting the quality improvement and the efficiency improvement of the coal preparation plant. The treatment of the coal slurry water in the coal preparation plant mainly comprises five links of grading concentration, sorting, desliming and dewatering, settling and filtering and dewatering. In the above links, because the coal slime has fine granularity, the sedimentation process is influenced by the combined action of buoyancy, mutual collision resistance, gravity and water flow impact force, the sedimentation process is complex and slow, and a large-scale concentration tank is generally required to be built as the equipment for sedimentation of the coal slime, so the sedimentation effect of the coal slime is a key factor for measuring the working efficiency of the automatic concentration system for treating the coal slime water. As the slime water is gradually settled to the bottom of the concentration tank, the settling speed needs to be monitored in the settling process, the dosage of the coagulant and the flocculant is determined according to the settling speed, and the settling speed can be fed back through the concentrations at different heights. The traditional detection mostly adopts an ultrasonic interface instrument to detect the concentration of the coal slime water. The ultrasonic interface instrument requires a solid-liquid obvious interface, which causes inaccurate monitoring and larger error of the existing detection method on the sedimentation effect of the coal slime in the concentration tank and brings much trouble to the actual detection work. Meanwhile, even if the concentration of the slime water is determined, the reagent adding work is still required to be carried out through independent reagent feeding equipment, the whole adding process is extremely time-consuming and labor-consuming, and obviously the requirement of modern production enterprises cannot be met.

Taking one of the samples as an example, the coal slime water enters one of the sampling pipes through the flexible connecting pipe, and the weights of the coal slime water samples at different heights above and below the concentration tank can be obtained through the weighing sensor; since the lower slurry sample is at a higher concentration than the upper sample, the weight measured below is greater than above. After the weight is obtained, the concentration of the slime water at the current height can be obtained through calculation, and the dosage of the coagulant and the dosage of the flocculant to be added are calculated.
