The center point of the rotating block 6 after the cooperation with the rotating groove 8 coincides with the center point of the arc groove 13, and a shaking material assembly for shaking and sliding impurities on the filter plate 4 is arranged on the mounting frame 9, and symmetrically distributed blocks 26 are fixedly connected to one side of the top of the sewage tank 1, and the two blocks 26 are symmetrically arranged with the limiting block 7 as the center axis, and the two blocks 26 are respectively located at the top of the corresponding guide groove 3.

[0024] The shaking material assembly includes a sliding plate 14 slidably connected to the side wall of the mounting frame 9, a groove 15 is provided at the bottom of the sliding plate 14, a first spring 16 is fixedly connected between the top of the sliding plate 14 and the mounting frame 9, a first rack 17 is fixedly connected to the top of the sliding plate 14, a strip groove is provided at the upper part of the mounting frame 9, a first guide block 18 is fixedly connected to the side wall in the strip groove, the first guide block 18 is slidably connected to the side wall of the first rack 17, a rotating shaft 19 is rotatably connected in the strip groove, and a spur gear is fixedly connected to the rotating shaft 19 20 and the toothless gear 21, the first rack 17 is meshed with the spur gear 20, the spur gear 20 is located on the rear side of the toothless gear 21, the left side of the toothless gear 21 is meshed with the second rack 22, a second guide block 23 is fixedly connected to the side of the strip groove away from the first rack 17, the second guide block 23 is slidably connected to the second rack 22, a second spring 24 is fixedly connected between the second guide block 23 and the top of the second rack 22, and a touch frame 25 for colliding with the filter plate 4 is fixedly connected to the bottom of the second rack 22.

[0025] Working principle: When the sewage is subjected to impurity separation, the user pumps the sewage into the sewage tank 1 through an external device. The sewage pumped into the sewage tank 1 then falls downward under the action of gravity and is filtered through the filter plate 4 to separate the sewage from the impurities therein. Since the filter plate 4 is arranged in an inverted quadrangular pyramid shape, the impurities filtered out on the filter plate 4 will gather along the inclined surface to the middle thereof, so as to avoid the filtered impurities piling up and clogging the filter plate 4, thereby affecting the impurity separation of the sewage. After a period of time, the user can start the winding machine 10 to wind up the pull rope 11 to move the filter plate 4 upward as a whole, and the filter plate 4 can be stabilized by the cooperation of the guide groove 3 and the guide ball 5 on the filter plate 4. The filter plate 4 moves upward as a whole, and the filter plate 4 moves upward, driving the rotating block 6 thereon to move upward and enter the rotating groove 8. At this time, the left side of the filter plate 4 is limited by the magnetic cooperation between the rotating block 6 and the limiting block 7, and the guide ball 5 on the left side is limited by the stopper 26. The winder 10 continues to reel in the pull rope 11, which will cause the right part of the filter plate 4 to swing upward. At the same time, the guide ball 5 on the right side of the filter plate 4 enters the corresponding arc groove 13. When the right side of the filter plate 4 swings upward, it will contact the groove 15 and push the sliding plate 14 and the first rack 17 connected thereto to move upward. During the upward movement of the first rack 17, the first guide block 18 makes its movement more stable. 16 is compressed accordingly, the first rack 17 moves upward and drives the toothless gear 21 to rotate through the spur gear 20 and the rotating shaft 19. When the toothless gear 21 is meshed with the second rack 22, the rotation of the toothless gear 21 will cause the second rack 22 to move downward. During the downward movement of the second rack 22, the second guide block 23 makes its movement more stable. The second spring 24 is compressed accordingly, and the second rack 22 moves downward to drive the touch frame 25 to collide with the filter plate 4. The filter plate 4 shakes and causes the impurities on it to slide to the left along the inclined surface formed after its swing. Because the cross section of the rotating block 6 is a triangle, the hypotenuse of the rotating block 6 can divert and guide the impurities sliding to the left on the filter plate 4. When the toothed gear 21 rotates and no longer meshes with the second rack 22, the second rack 22 moves upward and resets under the action of the second spring 24 connected thereto. To this end, the toothless gear 21 continuously cooperates with the second rack 22, so that the touch frame 25 can continuously move downward and collide with the filter plate 4, so that the impurities on the filter plate 4 can slide off. Then the user starts the winder 10 to release the pull rope 11, and the right side of the filter plate 4 swings downward accordingly. When the filter plate 4 swings to a horizontal state, the guide balls 5 are all located in the corresponding guide grooves 3 at this time, and the winder 10 continues to release the pull rope 11. After the filter plate 4 slides downward to its original position by itself under the action of gravity, the winder 10 is closed.
