Thickener and control method thereof

Abstract

The invention belongs to the technical field of thickeners, and discloses a thickener and a control method thereof. The thickener comprises a thickener body and a clear water layer depth detection unit, the clear water layer depth detection unit is arranged on the thickener body and is used for monitoring the depth of a clear water layer in the running process of the thickener body in real time. According to the thickener and the control method thereof provided by the invention, the depth of the clear water layer of the thickener can be stably measured, the action of the thickener is controlled based on the depth, and the stability of clear water circulation in a system can be ensured while the normal operation of the thickener is ensured.

Description

technical field [0001] The invention relates to the technical field of thickeners, in particular to a thickener and a control method thereof. Background technique [0002] In the beneficiation industry, the thickener is the core equipment of the beneficiation and concentration process. The working state of the thickener is related to the operation stability of the entire beneficiation process. The indicators for evaluating the working quality of the thickener include underflow concentration, drive shaft pressure and other indicators; underflow concentration can be monitored with an online densitometer, and drive shaft pressure can be monitored with a pressure sensor. However, with the diversification of processed mineral materials, the status of minerals with high specific gravity, low specific gravity, coarse particles and fine particle size is different, and the effect of suspension and precipitation of each material in the thickener is very different, so it is difficult t...

AI Technical Summary

Problems solved by technology

However, with the diversification of mineral materials to be processed, the states of high specific gravity, low specific gravity, coarse particle size and fine particle size of mineral types are different. The effects of suspension and sedimentation of each material in the thickener are very different, and it is difficult to prepare and judge the thickening. The amount of material in the machine and the state of existence, with the continuous operation of the thickener, only based on the two detection indicators of the underflow concentration and the drive shaft pressure to increase or decrease the output of the thickener, adjust the underflow concentration, etc., it is easy to adjust the lag and judge Inaccurate and other phenomena, resulting in the amount of clean water in the system being lower than the set range, deteriorating process parameters, and even affecting the efficiency of the thickener and the stability of the entire production system.
