[0060] Referring to FIG. 5, the limiting column 203i is fixedly arranged on one side of the baffle one 201c away from the cavity 102, and in the embodiment, the limiting column 203i is provided with two, one of which is arranged in the middle part of the baffle one 201c, and the other is arranged in the lower half of the baffle one 201c, and the two limiting columns 203i are distributed on a vertical line, the limiting slot one 203j comprises a vertical section 203j-1 and an inclined section 203j-2 adjacent to the vertical section 203j-1, and because the limiting column 203i in the embodiment is provided with two, the inclined section 203j-2 is also provided with corresponding two; in the initial state, the two limiting columns 203i are distributed at the top of the other inclined section 203j-2, and the toothed plate two 203h is located at the lower side of the blowdown tank 101, because the toothed plate two 203h can only slide up and down, and the baffle one 201c can only slide forward and backward due to the limitation of the movable slot one 101g, it is provided that when the toothed plate two 203h moves upward, the inclined section 203j-2 moves upward synchronously to drive the limiting column 203i and the baffle two 202d to move leftward, to drive the two movable plates one 201b and the push plate 201a to move synchronously in the direction of the filter plate 103, so that the opening frame 201a-1 opens the filter plate 103, when the two limiting columns 203i are both moved into the vertical section 203j-1, the opening part 201 can keep the filter plate 103 in the opening state as a whole, which is convenient for the cleaning part 202 to brush.

[0061] When the toothed plate 203f moves up and down, it can drive the movable plate and the cleaning plate 202b and the cleaning plate 202c to move up and down synchronously through the connecting belt, so that the cleaning plate 202b and the cleaning plate 202c clean the filter plate 103 up and down. As known from the foregoing, the baffle plate 202d is fixedly arranged at the bottom edge of the movable groove 101d, blocks the movable groove 101d, and prevents the sewage in the cavity 102 from entering the inside of the side of the sewage tank 101. The length of the part of the movable plate 202a sliding in the movable groove 101d is the same as the length of the baffle plate 202d. The cleaning plate 202b and the cleaning plate 202c are fixedly installed between the uppermost side and the lowermost side of the two movable plates 202a, so that the movable plate 202a can clean the filter plate 103 sufficiently during the up and down movement. Because the connecting block 203e is located at the lowest end of the movable plate 202a, when the movable plate 202a is located at the uppermost side, the top of the baffle plate 202d is inserted into the bottom of the movable plate 202a. The movable plate 202a and the baffle plate 202d cooperatively block the movable groove 101d. When the toothed plate 203f drives the movable plate 202a to move down through the connecting plate, the side of the movable groove 101d close to the cavity 102 is shielded by the inner wall of the sewage tank 101, so that no water leaks. The baffle plate 202d is inserted deeper into the movable plate 202a, until the movable plate 202a moves to the lowest position. The movable plate 202a can block the sewage from entering the inside of the side of the sewage tank 101 during the movement.

[0062] In the initial state, the toothed plate 203f is located at the highest position, the toothed plate 203h is located at the lowest position, the support plate 201 is not in contact with the filter plate 103, and is spaced apart from the filter plate 103 by a distance, so as to prevent the filter plate 103 from being blocked and affecting the filtering function of the filter plate 103. In addition, the push plate 201a is provided with multiple cavities, which can also play a certain filtering role. In addition, the holes on the push plate 201a are larger than the areas of the filter hole 103a-6 and the filter hole 103a-7 in the filtering state.

[0063] When the output shaft 203a rotates counterclockwise, the rotating column is synchronously rotated by rotating the rotating rod 203b, because the rotating column is movably arranged in the limiting frame 203c and the limiting frame 203c is fixedly arranged on the tooth plate one 203f, the rotating column can drive the tooth plate one 203f to move downward through the limiting frame 203c, and the tooth plate one 203f moves downward to drive the gear 203g to rotate counterclockwise to drive the tooth plate two 203h to move upward, in the process of moving upward of the tooth plate two 203h, the push plate 201a is driven to move to the direction of the filter plate 103 through the inclined section 203j-2 of the limiting groove one 203j to deform the filter plate 103 to the direction of the sewage cavity 102a, expand the filter hole one 103a-6 and the filter hole two 103a-7, and the height of the inclined section 203j-2 is relatively short, the tooth plate two 203h moves a small distance, and the limiting column 203i can quickly enter the vertical section 203j-1 at the same time, at the same time, the cleaning plate one 202b and the cleaning plate two 202c move downward to clean the expanded filter plate 103, until the tooth plate one 203f moves to the lowest position, the tooth plate two 203h moves to the highest position, the rotating column drives the rotating frame to continue to move, the tooth plate one 203f moves upward, the tooth plate two 203h moves downward, the cleaning plate one 202b and the cleaning plate two 202c upwardly clean the expanded filter plate 103, the limiting column 203i moves in the vertical section 203j-1, until the tooth plate two 203h moves downward to the limiting column 203i synchronously enters the inclined section 203j-2, the push plate 201a is retracted, the bristles of the cleaning plate one 202b and the cleaning plate two 202c can push the expanded part 201 of the filter plate 103, and the telescopic rod one 103a-2 and the telescopic rod two 103a-5 are relatively flexible, even if the bristles cannot push the filter plate 103 back, the new sewage can push the filter plate 103 back after entering; the output shaft 203a rotates one circle and rotates, the expanded part 201 and the cleaning part 202 enter the next activity period to reciprocatingly clean the filter plate 103.

[0064] The remaining structure is the same as that of example 2.
