DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] In this embodiment, a cavity 4 is opened inside the connection box 3, and the guide plate 5 is a hollow structure. The cavity 4 is connected with the overflow chamber 2 and the guide plate 5. The guide plate 5 is inclined and fixedly connected to the connection box 3.

[0023] Specifically, when sewage is precipitated, the sewage enters the sedimentation tank 1 , and as the water level rises, the sewage moves upward along the guide plate 5 , so that the sewage is precipitated in the sedimentation tank 1 and the guide plate 5 , and the clear water after precipitation flows into the overflow chamber 2 .

[0024] The bottom of the sedimentation tank 1 is a conical structure, and a reciprocating screw 13 is fixed at one end of the rotating shaft 8, and the reciprocating screw 13 corresponds to the block 17. A nut 14 is installed on the reciprocating screw 13, and a sliding rod 15 is fixed on the peripheral side of the nut 14. The sliding rod 15 is slidably fitted in the discharge port 9, and the sliding rod 15 corresponds to the block 17. A support rod 16 is fixed on the sliding rod 15, and the support rod 16 is fixedly connected to the block 17, and the block 17 is slidably connected to the reciprocating screw 13. The connecting box 3 is a circular structure, and the mixing tube 7 is fixed to the relative inner side of the connecting box 3. A rotating plate 10 and a stirring rod 12 are fixed on the peripheral side of the rotating shaft 8. The water inlet pipe 6 is tangent to the mixing tube 7, and the water inlet pipe 6 corresponds to the rotating plate 10.

[0025] Specifically, when sewage needs to be treated, the sewage is sent into the mixing tube 7 through the water inlet pipe 6, and the flocculant is sent into the mixing tube 7 through the feeding pipe 11. At this time, the sewage pushes the rotating plate 10, so that the rotating plate 10 drives the rotating shaft 8 to rotate, and the sewage and the coagulant can be mixed. The rotating shaft 8 drives the reciprocating screw 13 to rotate, thereby driving the sliding rod 15 to slide up and down, and driving the blocking block 17 to slide up and down. The blocking block 17 periodically blocks the discharge port 9. When the discharge port 9 is not blocked, the sludge can be flushed out, thereby realizing automatic sludge cleaning.
