Intelligent control method for liquid level of lepidolite flotation system

Abstract

The invention discloses an intelligent control method for the liquid level of a lepidolite flotation system. The intelligent control method comprises the steps that 1, a flotation machine liquid levelmeasurement value and a middling pump pool liquid level measurement value in flotation operation are obtained in real time; 2, a change trend is obtained according to the recorded liquid level measurement value of a flotation machine and the recorded liquid level measurement value of a middling pump pool; 3, according to the deviation between the real-time flotation machine liquid level measuredvalue and the flotation machine liquid level set value and the change trend of the flotation machine liquid level measured value, the opening degree of a flotation machine underflow cone valve is automatically adjusted according to the set value variable quantity, determined through a flotation machine liquid level control rule, of the flotation machine underflow cone valve, and the actual liquidlevel is made to be consistent with the liquid level set value; and 4, the set value of the liquid level of a scavenging flotation machine is automatically adjusted through the flotation machine liquid level cooperative control rule according to the change trend of the measured value of the liquid level of the middling pump pool until the set value is stable. The method can ensure that the liquidlevel of the lepidolite flotation system is rapidly stabilized within a reasonably set range, production indexes are stabilized, and stable operation of the flotation process is ensured.

Description

technical field [0001] The invention relates to the control field of a flotation system for dressing and smelting, in particular to an intelligent control method for the liquid level of a lepidolite flotation system. Background technique [0002] For the lepidolite flotation process in the mineral processing process, in view of its limited output, the flotation equipment is mostly small flotation machines of 2 to 3 cubic meters. [0003] However, the flotation equipment of the existing lepidolite flotation system has a small volume and limited buffer capacity. If the conventional PID control is used, the flotation liquid level will easily fluctuate greatly, resulting in large fluctuations in the production rate of each operation during the production operation. The stability of product quality has had a great impact. In addition, due to the lack of linkage between the operating equipment, the entire flotation process has poor ability to resist incoming ore disturbances, and...
