Design and Application of Bottom Coal Cleaning Device for Belt Conveyor
In order to reduce the amount of coal accumulation at the bottom of the belt conveyors and the amount of coal attached to the conveyor belts,mines are generally equipped with a coal cleaning device on belt conveyors.However,affected by multiple factors such as the working efficiency of the coal cleaning device and the long-term high load operation of the belt conveyors,coal accumulation still occurs at the bottom of the belt conveyors.However,the conventional manual cleaning method has problems such as large safety risks,poor work environment and high labor intensity.To this end,taking DTL 120/150/2×315 belt conveyor in 13503 fully-mechanized mining face of Shanxi A Mine as the research object,a belt conveyor bottom coal cleaning device was constructed,the mechanical structure and control mode of the cleaning device were designed in detail,and its engineering application effect was discussed.The results showed that the designed bottom coal cleaning device run smoothly,the efficiency of coal cleaning was high,the number and the labor intensity of underground coal cleaning workers can be significantly reduced,and the application effect was outstanding.
