Application practice of intelligent shallow slot separator control system in Yangcheng Coal Mine preparation plant
In order to improve the accuracy and stability of the shallow slot separator,an intelligent control system was designed by controlling the upwelling in the sorting process.The upwelling velocity prediction model was established by measuring the density of the separation area with a differential denser meter.The deviation between the actual value of the heavy medium suspension and the set value,the opening of the pulsating valve and the adjustment of the frequency converter were taken as the input variables of the model.The opening of the pulsating valve was calculated by the model.The industrial test shows that the system has good real-time performance,high control accuracy,effectively solves the stability of the flow field of the shallow-trough separator,improves the yield of cleaned coal,and reduces the ash content of cleaned coal.
