The first support shaft 5 and the second support shaft 6 are located on the same horizontal axis. The first support shaft 5 and the second support shaft 6 penetrate the outer shell 2 and are rotatably installed on the bracket 1. The two ends of the outer shell 2 have through holes for the first support shaft 5 and the second support shaft 6 to pass through. The second support shaft 6 is driven to rotate by a power mechanism, thereby driving the sieve drum 3 to rotate. A plurality of sieve holes 4 are opened on the circumferential wall of the sieve drum 3. The circumferential wall is a curved side wall on the sieve drum 3. The sieve holes 4 are used for filtering.

[0024] The first support shaft 5 is provided with a water injection hole 7 connected to the screen drum 3. The outer end of the first support shaft 5 is connected to a water injection pipe 10 through a water pipe rotating structure. The water injection pipe 10 is connected to a drainage pipe for conveying liquid to be filtered. The water injection pipe 10 is connected to the first support shaft 5 through the water pipe rotating structure. The water pipe rotating structure is a prior art, so that the water injection pipe 10 is sealed and rotatably connected to the first support shaft 5, which does not affect the rotation of the screen drum 3.

[0025] The cleaning mechanism is arranged in the sieve drum 3 for cleaning the upper end of the sieve drum 3. A mounting hole 8 connected to the sieve drum 3 is penetrated in the second support shaft 6. The cleaning mechanism extends outward through the mounting hole 8 and is fixedly connected to the bracket 1. The cleaning mechanism is not fixedly connected to the sieve drum 3 but is fixedly connected to the bracket 1, so that the position of the cleaning mechanism is fixed and does not rotate with the rotation of the sieve drum 3, so that the sieve holes 4 of the sieve drum 3 can be cleaned as the sieve drum 3 rotates.

[0029] The connecting rod 16 is rotatably connected to the second support shaft 6 through the shaft sealing structure, and the rotation of the second support shaft 6 will not drive the connecting rod 16 to rotate. In addition, the shaft sealing structure blocks the mounting hole 8 to prevent the liquid in the screen drum 3 from flowing out of the mounting hole 8.

[0030] According to a preferred technical solution, the sieve drum 3 is in the shape of a transversely arranged frustum, and the inner diameter of the sieve drum 3 gradually decreases from one end toward the other end.

[0031] The impurity particles sieved out of the sieve cylinder 3 can be gathered at the end of the sieve cylinder 3 with a larger size, and will not cover the entire lower end of the sieve cylinder 3, thereby reducing blockage during filtration.
