Flow type coal washing device with scraping and filtering mechanism for coal mine

The flowing type coal washing device comprises an outer box body and a coal washing mechanism which is movably installed in the outer box body, when the flowing type coal washing device is used, an operator fills a water tank with water and pours coal briquettes into a conical bin, the coal briquettes can be retained at the upper end of a coarse filter screen, a water pump is started to work, and the coal washing mechanism is started to wash the coal briquettes. Water in the water tank enters the water pipe and flows out from the water outlet so as to flow to the surfaces of coal briquettes, dust on the surfaces of the coal briquettes is washed off in the flowing process, the dust penetrates through the coarse filter screen and is stored at the upper end of the fine filter screen, and the water penetrates through the coarse filter screen and the fine filter screen and is stored at the bottom of the conical bin, so that separation of the coal briquettes, the dust and the water is facilitated.
