Objects in the sewage will settle to the bottom of the square sedimentation tank 11 and gather to the auger spiral blade 112 through the slope 111. Then, the auger spiral blade 112 can send the objects out of the discharge channel 114 through the open valve 115, and the treated sewage can be sent out through the drainage pipe 116 connected to the water pump. The plug 117 can prevent the precipitated objects from being discharged along with the sewage through the drainage pipe 116.

After the capture net bag 123 blocks a certain amount of objects, the rotary screening unit 12 is pulled upward as a whole by the high and low displacement unit 13, and then the motor three 129 is operated, the motor three 129 pulls the sprocket two 128 to rotate, and the sprocket two 128 pulls the chain 127 to move the chain 127. The wheel 126 rotates, the chain 127 pulls the assembly rod 122 to rotate, and the assembly rod 122 pulls the four capturing net bags 123 to rotate, thereby rotating the capturing net bag 123 that has not yet contained any object to the bottom, and then moves toward the bottom through the high and low displacement unit 13 to fit the lower wall of the water supply channel 17, and then blocks the object. The capturing net bag 123 containing a large number of objects rotates to be separated from the sewage, and the liquid in the objects is filtered out. After being air-dried or air-dried, it is moved by the discharge piece 124 to the discharge box 15.

[0044] A handle 153 is installed on the wall of one end of the unloading box 15, and a sliding bar 152 is installed at the bottom of the unloading box 15. The sliding bar 152 is slidably connected to the displacement cavity 143. The displacement cavity 143 is installed at the head of the supporting piece 142, and the supporting piece 142 is fixedly connected to one side of the assembly frame 14; the head of the wall of the unloading box 15 is pinned to the guide piece 155 via an elastic member 154, and the elastic member 154 is a spiral beryllium copper wire and can generate opposite torque when the rotation deformation is restored. The guide piece 155 and the unloading piece 124 are adapted to each other; the unloading piece 124 is located at the head of the guide piece 155 under the unloading piece 124 during the object unloading stage, and the unloading piece 124 pulls the guide piece 155 to rotate during the rotation. After the unloading piece 124 and the guide piece 155 are separated, the guide piece 155 returns to the initial position via the elastic member 154.

[0045] The weakening unit 16 includes a concave shell 162, a connecting shell 163, a compensation piece 164 and a power unit 165; the concave shell 162 is fixedly connected to the upper and lower walls of the assembly frame 14 via the connecting shell 163; four compensation pieces 164 are installed, which are evenly rotated and installed inside the concave shell 162; the power unit 165 is installed at the head of the concave shell 162 and swings through the linkage pulling compensation piece 164.

[0046] The head of the compensation piece 164 is fixedly connected to the rotating rod 2 1642, and the compensation piece 164 is screwed to the concave shell 162 via the rotating rod 2 1642; the power unit 165 includes a motor 5 1652, a rotating rod 3 1653, an assembly block 1654, a conical platform 1 1655 and a conical platform 2 1656; the motor 5 1652 and the assembly block 1654 are fixedly connected to the head of the concave shell 162, and one end of the rotating rod 3 1653 and The power end of motor five 1652 is fixedly connected, and the other end of rotating rod three 1653 is screwed to assembly block 1654; conical platform one 1655 is fixedly installed on rotating rod three 1653, and a tooth gap is reserved on the surface of conical platform one 1655; conical platform two 1656 is fixedly installed on the head of rotating rod two 1642, and a tooth gap is reserved on the surface of conical platform two 1656, and conical platform one 1655 and conical platform two 1656 are engaged with each other.

[0047] During the use of the weakening unit 16, when the rotating screening unit 12 is stationary, the sewage surface in the water supply channel 17 and objects mixed in the sewage and floating on the liquid surface are blocked by the capture net bag 123 below. At this time, the four offset plates 164 in the weakening unit 16 rotate to form an angle, which has the effect of reducing the flow rate of the sewage on one hand, and does not hinder the movement of the sewage on the other hand, preventing the sewage from flowing fast and exerting a large pressure on the capture net bag 123, causing the capture net bag 123 to be damaged, and preventing the capture net bag 123 from having to be repaired and replaced many times, so that the capture net bag 123 can be used for a long time.

[0048] During the rotation of the rotating screening unit 12, before the objects in the capturing net bag 123 below are lifted up and away from the sewage, the four offsetting plates 164 in the weakening unit 16 are rotated to form a flat surface, thereby forming an integral offsetting component that can block the mixed objects. The operation process is to operate the motor five 1652, the motor five 1652 pulls the rotating rod three 1653 to rotate, the rotating rod three 1653 pulls the four conical tables one 1655 to move together, the four conical tables one 1655 pull the matching conical table two 1656 to rotate, the four conical tables two 1656 pull the corresponding rotating rod two 1642 to rotate, thereby rotating the four offsetting plates 164 to form a complete surface.

[0049] The specific implementation method is as follows: during use, the power unit 165 is used to change the four offset plates 164 to rotate together to an angled shape, so that the sewage and the mixed objects in the sewage can move out from the open areas of the offset plates 164 that are close to each other, and the pressure caused by the movement speed of the sewage can be reduced by the four offset plates 164. The capture net bag 123 under the rotating screening unit 12 can block the objects on the liquid surface of the water supply channel 17 and in the sewage that are large in volume and not conducive to sedimentation. After the capture net bag 123 is filled with a large number of objects, the power unit 165 pulls the four offset plates 164 to rotate together to form a complete surface, forming an integral offset component without gaps. At this time, the sewage can flow out from the leaking port of the offset plate 164 and can block the objects; the high and low displacement unit 13 pulls the rotating screening unit 12 toward the high The catching net bag 123 containing objects is displaced, and then the sprocket 126, the chain 127, and the sprocket 2 128 cooperate to rotate the catching net bag 123 containing objects to be separated from the sewage, and then the catching net bag 123 without objects is rotated downward; the high and low displacement unit 13 then pulls the rotating screening unit 12 to displace downward, so that the catching net bag 123 without objects fits against the lower wall of the water supply channel 17, and then blocks the movement of the objects, and the catching net bag 123 containing objects is rotated to be separated from the sewage, and the liquid in the objects is filtered out. After being air-dried or air-dried, it is unloaded into the unloading box 15 by the unloading piece 124, and then the power unit 165 changes the four offset pieces 164 to rotate together to an angled shape, so that the sewage and the mixed objects in the sewage can move out from the open areas of the offset pieces 164 close to each other, and the operation is repeated.
