Mining Belt Conveyor Header Coal Cleaning Device Design and Application
Based on the traditional belt conveyor head clearing device structure is simple,low level of automation,poor coal clearing effect,belt conveyor in the transportation of coal gangue deformation of serious failure rate,and the roller slurry attached to the amount of large,resulting in belt conveyor running tear belt accidents,serious constraints on the safe and efficient transportation of the mining face,Xueping Coal Mine through a technical study on the 8204 face DTL-120-type belt conveyor original clearing device main problems.Through technical research,Xueping coal mine analyzed the main problems of the original coal cleaning device of 8204 working face DTL-120 belt conveyor,and carried out reasonable optimization and improvement according to the current situation of transportation,designed a set of new cleaning device with cleaning function,analyzed the structure and working principle of the cleaning device,and through the actual application of the effect of the field,the optimized cleaning device failure rate was reduced to less than 5％,the efficiency of coal cleaning was increased to more than 90％,and the cost of reducing the maintenance of the equipment was 174,000 yuan,and significant results were achieved.174,000 yuan,and achieved significant application results.
