Finally, the impurities are collected, and the second rod and the bevel gear 4 are driven to rotate by the motor 41, and the first belt teeth and the second belt teeth are driven by a set of second gears 42 and third gears 44, so that a pair of first rods 14 and the disc rotate, and at the same time, the hollow cylinder 22 is driven to rotate around the inner wall of the filter cylinder 2. According to whether there are large impurities in the fluid, the first gear 1 is controlled by the control unit. 5 rotates, and then the position of the collecting box 16 is changed. When there are large impurities in the fluid, the electromagnetic layer 52 is powered off to make the electromagnetic layer 52 lose its magnetism, and the electromagnetic block 53 is squeezed into the first square groove 5 by the spring, and then the first rod 14 drives the first gear 15 to rotate, and then the first gear 15 is meshed with the outer gear ring 13 to change the position of the collecting box 16. When the connecting rod 23 is driven to make an eccentric movement by the rotating block 24, the transmission gear 62 on the connecting rod 23 is meshed with the inner gear ring 61 and the rotating gear 6, and because the connecting rod 23 and the hollow cylinder 22 are fixedly connected, when the hollow cylinder 22 rotates around the inner wall of the filter cylinder 2, the hollow cylinder 22 rotates by itself, and when it contacts the impurities on the filter hole, the rotational force brought by the rotation of the hollow cylinder 22The impurities can be better knocked off from the filter holes to avoid clogging of the filter holes. The self-rotation of the hollow cylinder 22 can better squeeze the fluid and increase its filtering efficiency. The establishment of the twisted groove 7 can make the hollow cylinder 22 rotate, which can improve the movement efficiency of the fluid and impurities around the inner wall of the filter cartridge 2, provide guidance for it, and make the fluid position move around the inner wall of the filter cartridge 2, so that the whole area can be better filtered out through the filter cartridge 2. The impurities are guided by the twisted groove 7 and moved to the elbow 26 to be discharged. The establishment of the spiral groove 82 provides a guiding path for the impurities, which can increase the distance that the impurities move upward without affecting the fluid in the middle. When the impurities accumulate in the stagnation groove 8 and rotate around the stagnation groove 8, they are output through the output pipe 81, so as to better separate the solid and liquid, and collect the impurities and liquid. The establishment of the suction pump can extract the impurities in the collection box 16, and collect the impurities in the elbow 26 and the impurities in the stagnation groove 8, so as to increase the efficiency and effect of impurity collection.
