[0027] The working principle of the multi-stage filtration device for coal mine water provided by this utility model is as follows:

[0028] When performing multi-stage filtration of mine water, the mine water is pumped into the filter box 7, and then the filter plate 15 located on the inner side filters the mine water. The filtered well water flows into the classification chamber through the guide plate and guide port, and flows downward in the classification chamber. During the flow, the filter screen 13 performs staged filtration of the well water. Then the filtered well water flows into the activated carbon 4, and the activated carbon 4 adsorbs the fine impurities in the well water. The adsorbed well water flows back into the placement chamber 3. The filter sponge 2 set in the placement chamber 3 adsorbs the small particles in the well water. The filtered well water is discharged through the drain port 10.

[0029] When the mine water is filtered inside the filter box 7, the brake motor 602 located at the top works, and the output end rotates to drive the transmission shaft below to rotate.
