Abstract

The invention discloses a device for measuring the material level and the concentration in a thickener. The device includes an execution mechanism, a detection mechanism, and a processing and displaymechanism. The execution mechanism includes a heavy hammer, a winding wheel, a pulley and a servo motor. The detection mechanism includes a lever, a pressure sensor and a coder, and the processing anddisplaying mechanism includes a PLC and a displayer; the heavy hammer is connected to one end of a rope, the other end of the rope is wound on the winding wheel after bypassing the pulley, the winding wheel is in transmission connection with the servo motor, and the winding wheel is driven by the servo motor to rotate; the pulley is connected with one end of the lever, the pressure sensor is connected with the other end of the lever, the coder is arranged at the winding wheel and used for recording number of turns of rotation of the winding wheel, the pressure sensor and the coder are connected with the PLC, and the PLC is connected with the displayer. The device can measure the material level and the material concentration of a deposit layer in the paste thickener at the same time, the structural design is reasonable and the measuring cost is low.

Description

technical field [0001] The invention relates to a device for measuring material level and concentration in a thickener, and a method for measuring the material level and concentration in a thickener by using the device, belonging to the field of material level and concentration measurement of a sediment layer formed during pulp dehydration. Background technique [0002] Thickener is a kind of dehydration equipment widely used in metallurgy, chemical industry, coal, non-metallic mineral processing, environmental protection and other industries, and is used for the treatment of concentrate and tailings in the mineral processing industry. The paste thickener is improved on the basis of the thickener, and it is a new type of dehydration equipment combined with the filter characteristics of the mud layer, which has higher efficiency and better product quality. Such as figure 1 As shown, the slurry flows in from the upper part of the paste thickener and flows out from the bottom ...
