[0026] Preferably, a flipping device 7 is provided below the push plate 57, and the flipping device 7 includes a slip ring 71 and a fixed column 73. The slip ring 71 is slidably installed on the outer side of the rotating rod 52, and a spring is fixed to the bottom surface of the slip ring 71. An L-shaped protrusion rod 72 is fixed to the top of the slip ring 71. The fixed column 73 is fixed to the outer wall surface of the push plate 57, and a protrusion is fixed to the top of the L-shaped protrusion rod 72. The fixed column 73 is located on the movement trajectory of the L-shaped protrusion rod 72. The fixed column 73 drives the slip ring 71 to move downward by pushing the protrusion of the L-shaped protrusion rod 72, so that the slip ring 71 pushes the impurities accumulated on the surface of the filter screen 4 away from the rotating rod 52, so that it is convenient for the blade rod 58 and the fixed knife 510 to cut impurities such as branches, paper scraps, plastic bags, etc., and at the same time, the slip ring 71 pushes the impurities toward the spiral ring 63, so that it is convenient for the spiral ring 63 to lift and discharge the impurities.

[0027] When in use, the sewage to be treated is put into the circular baffle shell 2 in the device body 1, and the rotating rod 52 is driven to rotate by an external motor, and the rotating rod 52 drives the blade rod 58 to rotate. The blade rod 58 cuts impurities such as branches, paper scraps, and plastic bags in the sewage, and the impurities after cutting are easy to discharge. At the same time, some plastic bags will adhere to the outside of the blade rod 58. When the rotating rod 52 rotates, the rotating rod 52 drives the slide rail column 53 to rotate. Under the restriction of the fixed rod 54, the fixed rod 54 drives the slide rail column 53 to rotate while sliding in the inclined annular slide groove of the slide rail column 53. The sliding rail column 53 moves upward each time when the sliding rail column 53 moves downward, the sliding rail column 53 drives the push plate 57 to move away from the rotating rod 52 by pushing the hinge rod 56, and the push plate 57 pushes the plastic impurities adhering to the outer side of the blade rod 58 to separate from the blade rod 58, thereby avoiding the problem that the plastic impurities adhere to the outer side of the blade rod 58 and affecting the efficiency of the blade rod 58 in handling impurities; at the same time, the fixed knife 510 will intercept the plastic impurities adhering to the outer side of the blade rod 58, and cooperate with the blade rod 58 to cut the plastic impurities, thereby further improving the efficiency of cutting the plastic impurities.

[0028] At the same time, the rotating ring 62 is driven to rotate by an external pulley motor, and the rotating ring 62 drives the spiral ring 63 to rotate. When the spiral ring 63 rotates, the impurities chopped by the fixed knife 510 are lifted and discharged to the outside of the circular baffle shell 2, thereby facilitating the treatment of impurities in the sewage; at the same time, the rotating ring 62 drives the convex ball ring 65 to rotate, and the L-shaped rod 64 drives the convex ball ring 65 to move upward by pushing the convex ball block of the convex ball ring 65. When the L-shaped rod 64 does not push the convex ball block of the convex ball ring 65, the convex ball ring 65 moves downward under the action of gravity of the spiral ring 63, and the convex ball ring 65 drives the spiral ring 63 to move up and down, so that the spiral ring 63 shakes up and down in the process of rotating and lifting impurities, so that the spiral ring 63 drives the impurities to shake off excess moisture on the impurities, thereby improving the efficiency of subsequent moisture treatment in the impurities.

[0029] Each time the convex ball ring 65 moves upward, the convex ball ring 65 pushes the L-shaped resistance rod 83 to move upward, and the L-shaped resistance rod 83 drives the bevel ring 81 to move synchronously. When the convex ball ring 65 moves downward, the bevel ring 81 is reset by the spring plate 82 and moves downward, so that the bevel ring 81 swings up and down, and the bevel ring 81 drives the impurities that fall on the outside of the circular baffle shell 2 to swing, thereby improving the efficiency of the impurity discharge device body 1.

[0030] At the same time, when the push plate 57 moves along the blade rod 58 in the direction away from the rotating rod 52, the push plate 57 drives the fixed column 73 to move synchronously. The fixed column 73 drives the slip ring 71 to move downward by pushing the protrusion of the L-shaped protrusion rod 72, so that the slip ring 71 pushes the impurities accumulated on the surface of the filter 4 in the direction away from the rotating rod 52, so that it is convenient for the blade rod 58 and the fixed knife 510 to cut impurities such as branches, paper scraps, plastic bags, etc. At the same time, the slip ring 71 pushes the impurities toward the spiral ring 63, so that the spiral ring 63 can lift and discharge the impurities.
