Problems solved by technology

But this method still has disadvantages, because the flotation process is not a simple industrial process, it contains many difficult and complex automation technology difficulties, such as nonlinearity, time-varying, easy overshoot, multi-variable and random interference, which requires the control unit to have strong robustness and adaptability
It is incomplete to only detect and control parameters such as feed amount, feed concentration, and liquid level of the flotation machine without considering the coupling relationship between process parameters and other influencing factors, and cannot truly realize flotation. machine control optimization

Abstract

The invention relates to a flotation machine process control device and control method. A sensor in a detection system detects different working condition parameters in a flotation process and outputsthe detected parameters, and then the collected signals are converted into digital signals through a data acquisition card to be output; a computer in a controller performs optimization calculation on different working condition parameters according to the parameters output by each sensor in the detection system and an intelligent optimization algorithm module, and an optimized process parametercontrol signal is transmitted to an execution part; and after receiving the control signal transmitted by the computer, the execution part achieves the changes of the rotating speed of a motor, height(angle) of an impeller and height (angle) of a baffle plate by adjusting a servo motor. The method establishes an optimal matching model integrating multiple parameters into a whole body, ensures thenormal operation of the flotation machine by timely and properly adjusting each variable, greatly improves the accuracy of a process control system and achieves the automatic and intelligent controlof the flotation process.

Description

technical field [0001] The invention relates to a process control device and a control method of a flotation machine, in particular to a process control device and a control method in which parameters of a stirring process of a flotation machine change nonlinearly according to different working conditions. Background technique [0002] Flotation is a technology for sorting minerals, and it is also a major mineral processing method. Its main principle is based on the different physical and chemical properties of the mineral surface, the science and technology of sorting minerals on the gas-liquid-solid three-phase interface. The flotation process is a series of continuous processes from the preparation of ore raw materials before flotation to the output of concentrates. In the flotation process, there are many technological factors that affect the flotation process, but the more important ones are: the particle size of the ore, the concentration of the pulp, the chemical sys...
