A kind of intelligent control method of liquid level of lepidolite flotation system

Abstract

The invention discloses an intelligent control method for the liquid level of a lepidolite flotation system. According to the recorded liquid level measurement value of the flotation machine and the liquid level measurement value of the medium mine pump pool, the change trend is obtained; step 3, according to the deviation of the real-time measurement value of the liquid level of the flotation machine and the set value of the liquid level of the flotation machine and the The change trend of the measured value of the liquid level of the flotation machine, the change of the set value of the bottom flow cone valve of the flotation machine determined by the liquid level control rule of the flotation machine automatically adjusts the opening of the bottom flow cone valve of the flotation machine, so that the actual liquid level and the bottom flow cone valve of the flotation machine are automatically adjusted. The set value of the liquid level is the same; step 4, according to the change trend of the liquid level measurement value of the pump pool in the mine, automatically adjust the set value of the liquid level of the scavenger flotation machine through the coordinated control rule of the liquid level of the flotation machine until it is stable. The method can ensure that the liquid level of the lepidolite flotation system is quickly and stabilized within a reasonable set range, stabilizes the production index, and ensures the stable operation of the flotation process.

Description

technical field [0001] The invention relates to the control field of a flotation system for beneficiation and metallurgy, 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, due to the small volume of the flotation equipment of the existing lepidolite flotation system, the buffer capacity is limited. If the conventional PID control is used, the flotation liquid level will easily fluctuate greatly, resulting in large fluctuations in the yield 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 the disturbance of in...
