Research on PLC automatic control method of coal sorting equipment in coal preparation plant
In order to solve the problem of control defects in relay systems of traditional coal sorting equipment,ensure that the density and particle size of the sorted coal are within the standard range,improve the quality and production efficiency of the sorted coal,and a PLC based automated conveying control technology is constructed.Firstly,collecting coal samples,analyzing coal sorting process,setting the most complete coal particle size index according to different application scenarios of coal,classifying the coal ash content range,and obtaining the coal sorting density range,finally,combining coal density optimization control,particle size optimization control,and PID technology to dynamically adjust the amount and speed of coal transportation through proportional integrator micro molecule and achieve automated transportation control.Through experimental results,it has been proven that the proposed control method can determine appropriate sorting processes,improve the quality and actual productivity of sorted coal,ensure the stability of equipment pressure in the greatest extent possible,and provide a high-quality reference for the coal sorting fields.
