Coal washing device for coal mining

Abstract

The invention discloses a coal washing device for coal mining. The coal washing device comprises a supporting base, supporting legs are fixedly connected to the periphery of the bottom of the supporting base, the right end of the top of the supporting base is fixedly connected with a wind washing mechanism comprising a wind washing box, a draught fan, a spraying head, springs, a vibration motor, ascreen and second supporting plates through four supporting frames distributed at equal intervals. According to the coal washing device, the wind washing mechanism is arranged, so that the purpose ofconducting wind washing on coal at the top of the screen can be achieved; meanwhile, the vibration motor can drive the screen to vibrate under the action of the springs, so that the purpose of screening the coal is achieved; sliding bases and sliding devices are arranged, so that the purpose of driving the water washing mechanism to horizontally move is achieved; supporting rods, rotating shaftsand electric telescopic rods are arranged so that the coal can conveniently slide down along a third supporting plate; a water washing mechanism is arranged, so that the purpose of conducting water washing on the coal falling from a first discharging port and / or a second discharging port can be achieved; and meanwhile, a third motor can drive a water washing box to rotate, so that the coal in thewashing box is poured out.

Description

technical field [0001] The invention relates to the technical field of coal mines, in particular to a coal washing device used for coal mine development. Background technique [0002] Coal washing is an indispensable process in the deep processing of coal. The coal directly mined from the mine is called raw coal. Many impurities are mixed in the raw coal during the mining process, and the quality of the coal is also different. At the same time, coal washing is an industrial process to remove impurities in raw coal, or to classify high-quality coal and low-quality coal. However, the existing coal washing device has poor coal washing effect, thereby reducing the coal quality. Coal mines use coal washing devices. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a coal washing device for coal mine development, so as to solve the problems raised in the above background technology. [0004] In order to achieve the above purpose, the present ...

[0002] Coal washing is an indispensable process of coal deep processing. The coal directly mined from the mine is called raw coal. Raw coal is mixed with many impurities during the mining process, and the quality of coal is also different. Coal with small internal ash and large internal ash is mixed in At the same time, coal washing is an industrial process that removes impurities in raw coal, or classifies high-quality coal and low-quality coal. However, the existing coal washing device has poor coal washing effect, thereby reducing the quality of coal. Therefore, we propose a Coal washing device for coal mine development
