Self-adaptive control system of permanent magnet drum type magnetic separator

Abstract

The invention provides a self-adaptive control system of a permanent magnet drum type magnetic separator, which comprises an automatic monitoring system and an automatic control system which are connected with a separation cavity of the magnetic separator, and the automatic monitoring system is in signal connection with the automatic control system; the automatic monitoring system comprises a liquid level communication monitoring device and a magnetic system / magnetic cylinder rotation speed ratio monitoring system, the liquid level communication monitoring device is used for monitoring liquid level information in the separation cavity in real time, and the magnetic system / magnetic cylinder rotation speed ratio monitoring system is used for monitoring magnetic system / magnetic cylinder rotation speed information in real time; the automatic control system comprises a control pipeline, an information collection device, a control execution mechanism and a PLC control module, and the PLC control module receives signals of the automatic monitoring system and is in control connection with the control pipeline, the information collection device and the control execution mechanism. The system can monitor information of each control parameter in real time under different ore feeding conditions, and automatically adjust the control parameters within a certain range according to ore feeding fluctuation, so that the self-adaptive accurate control of the magnetic separator is realized.

Description

technical field [0001] The invention relates to the technical field of magnetic separation equipment, in particular to an adaptive control system for a permanent magnet drum type magnetic separator. Background technique [0002] Permanent magnet drum magnetic separator can be divided into static magnetic system and dynamic magnetic system according to the form of magnetic system. The dynamic magnetic system has many adjustable parameters. When in use, it is necessary to adjust the control parameters at any time according to the fluctuation of ore supply, including Rotating speed of drum, working efficiency of ore unloading device, adjustment of liquid level in separation chamber and adjustment of rinsing water volume, etc., the adjustment is more complicated, and the technical level of on-site operators is high. In many cases, the on-site operation level affects the operation status of the equipment. At the same time, it consumes a lot of manpower, resulting in a waste of ma...
