The bottom surface of the impeller 64 fits with the cylinder bottom 62, and the outer edge of the impeller 64 fits with the inner wall of the cylinder body 61. The blades of the impeller 64 are inclined at a certain angle to the cylinder bottom 62. When the fluid passes through the filter cylinder 6, it acts on the surface of the blades, thereby driving the blades to rotate, so that the impeller 64 can automatically scrape off impurities on the cylinder bottom 62 and the inner surface of the cylinder body 61 to prevent impurities from clogging the filter cylinder 6, thereby ensuring the flow rate of the filter cylinder 6.

[0027] A slag discharge groove 65 is provided at the bottom of the cylinder 61, one end of the slag discharge groove 65 is in contact with the cylinder bottom 62, the maximum distance from the slag discharge groove 65 to the cylinder bottom 62 is smaller than the maximum distance from the impeller 64 to the cylinder bottom 62, the slag discharge groove 65 is provided above the slag collecting cylinder 52, when the impeller 64 rotates, it pushes the impurities to move along the cylinder bottom 62 and the inner wall of the cylinder 61, when the impurities move to the slag discharge groove 65, the impurities enter the slag collecting cylinder 52 through the slag discharge groove 65, thereby reducing the impurities accumulated in the filter cylinder 6, collecting them, and avoiding blockage of the filter cylinder 6.
