The working principle of the above embodiment is as follows:

(1) when the filtration is performed, the water inlet pipe 407 enters the water injection, the water injection reaches the inside of the filter box 404, at this time, under the action of the motor 401, the connecting block 403 is driven to rotate by the pushing block 402, the filter box 404 further rotates along with the rotation, at this time, the water injection is centrifugally thrown out through the first filter screen 410, large-sized impurities reach the inside of the filter box 404, the thrown-out water injection reaches the inside of the concentration cover 501 through the water holes 3 and is discharged through the sedimentation pipes 502, at this time, the water injection does not directly contact with the second filter screen 506, the water injection slowly lifts up between the positioning plates 505 at the two sides, during the lifting process, most of the impurities are deposited on the bottom plate 507, the lifted water injection contacts with the second filter screen 506 and is discharged after double filtration, when the cleaning is performed, the cover plate 406 is taken down, at this time, the positioning pipes 408 and the pressure ring 409 at the lower side of the cover plate are moved out from the inside of the box 1, at this time, the upper side of the filter box 404 is not pressed by the pressing ring 409, and can be taken out from the inside of the case 1.

(2) When the filter box 404 moves upwards, the connecting block 403 can move outside the pushing block 402 and separate, when the filter box 404 rotates, the connecting block 403 is located outside the pushing block 402, because the pushing block 402 is a triangular prism, after the upper side and the lower side of the filter box 404 are located, the connecting block 403 can be driven to rotate by the operation of the motor 401, because the second filter screen 506 is in an inclined state, part of impurities can slide to the bottom plate 507 to be deposited, under the action of the water gun 504, the impurities on the second filter screen 506 can be washed away, when the filter is not used, after the bottom plate 507 is pulled, a channel is formed between the positioning plates 505 on the two sides, at the moment, the impurities can directly fall downwards and are discharged through the drain pipe, so the impurities under double filtration are very convenient to clean, and the working strength of workers is reduced.
