[0026] The bottom of the inner wall of the sedimentation tank 1 is rotatably installed with a stirring rod 4, the stirring rod 4 is fixedly installed with stirring blades 41 on the outer circumference thereof, a second bevel gear 42 is fixedly sleeved on the stirring rod 4 close to the top, a stirring pipe 5 is rotatably installed on the top of the stirring rod 4, a stirring plate 51 is fixedly installed on the outside of the stirring pipe 5, a third bevel gear 52 is fixedly sleeved on the top of the stirring pipe 5, a filter screen 6 is fixedly installed on the inner wall of the sedimentation tank 1 close to the top, and two material receiving plates 7 are slidably installed on the top of the filter screen 6 respectively.

[0027] The sedimentation tank 1 can guide the sewage into the sedimentation tank 1 through the connecting pipe 12 on one side, the flocculating agent is injected into the hopper 11, the sewage introduced can be subjected to flocculation and sedimentation treatment through the flocculating agent in the sedimentation tank 1, and after flocculation and sedimentation, the sedimentation tank 1 can be discharged through the connecting pipe 12 on the other side.

[0028] When the flocculating agent is injected into the top of the inner cavity of the sedimentation tank 1 through the hopper 11, the servo motor 2 drives the second bevel gear 42 and the third bevel gear 52 through the first bevel gear 21 on the output end, so that the stirring rod 4 can rotate at the bottom of the inner cavity of the sedimentation tank 1, and the stirring pipe 5 can rotate at the space on the top of the filter screen 6, so that the steel wire brush at the bottom of the stirring plate 51 can clean the flocculating agent blocked in the filter holes on the top of the material receiving plate 7 and the filter screen 6, and the subsequent flocculating agent cannot enter the sedimentation tank 1 to mix with the sewage, and at the same time, the stirring blades 41 can fully stir the flocculating agent and the sewage falling into the sedimentation tank 1, so that the cleaning of the filter screen 6 and the mixing of the sewage and the flocculating agent are simultaneously performed, thereby ensuring that the sufficient flocculating agent can fully contact with the sewage.

[0029] The two groups of semicircular material receiving plates 7 can be manually cleaned after being disassembled from the connecting grooves 72 through the sealing plug blocks 71.

[0030] The two groups of semicircular material receiving plates 7 can be manually cleaned after being disassembled from the connecting grooves 72 through the sealing plug blocks 71.

[0031] A connecting frame 31 is fixedly installed between the gearbox 3 and the inner wall of the hopper 11. The outer edge of the first bevel gear 21 meshes with the outer edges of the second bevel gear 42 and the third bevel gear 52, respectively. The stirring rod 4 is rotatably installed at the center of the gearbox 3 and the inner wall of the sedimentation tank 1. The stirring tube 5 is rotatably installed at the center of the top of the gearbox 3 and the filter screen 6. The filter screen 6 has a circular structure, and the receiving plate 7 has a semi-circular structure. The sieve holes on the surface of the filter screen 6 and the receiving plate 7 correspond one-to-one. A wire brush is fixedly installed on the side of the feeding plate 51 near the receiving plate 7. The motor 2 drives the second bevel gear 42 and the third bevel gear 52 through the first bevel gear 21 at the output end, so that the stirring rod 4 can rotate at the bottom of the inner cavity of the sedimentation tank 1 and the stirring tube 5 can rotate at the top space of the filter screen 6. This allows the wire brush at the bottom of the feeding plate 51 to clean the flocculant blocked in the filter holes at the top of the feeding plate 7 and the filter screen 6, preventing the flocculant from being unable to enter the sedimentation tank 1 and mix with the sewage. At the same time, the stirring blade 41 can fully stir the flocculant and sewage that fall into the sedimentation tank 1.

[0032] The receiving plate 7 has an integrally formed sealing block 71 on its outer side. The sedimentation tank 1 has connecting grooves 72 on both sides that match the sealing block 71. The sealing block 71 slides in the inner cavity of the corresponding connecting groove 72. The connecting groove 72 has a T-shaped structure inside. The sealing block 71 is fixedly installed in the inner wall of the connecting groove 72 by bolts. The two sets of semi-circular receiving plates 7 can be disassembled from the connecting groove 72 by the sealing block 71 and then slid out, so that the flocculant on the semi-circular receiving plate 7 can be manually cleaned.

[0033] Working principle: During use, wastewater can be introduced into sedimentation tank 1 through connecting pipe 12 on one side, and flocculant is injected into hopper 11;

[0034] When the flocculant is injected into the top of the inner cavity of the sedimentation tank 1 through the hopper 11, the servo motor 2 drives the second bevel gear 42 and the third bevel gear 52 through the first bevel gear 21 at the output end, so that the stirring rod 4 can rotate at the bottom of the inner cavity of the sedimentation tank 1 and the stirring tube 5 rotates at the top space of the filter screen 6. This allows the wire brush at the bottom of the feeding plate 51 to clean the flocculant blocked in the filter holes at the top of the feeding plate 7 and the filter screen 6, preventing the flocculant from not being able to enter the sedimentation tank 1 and mix with the sewage. At the same time, the stirring blade 41 can fully stir the flocculant and sewage that fall into the sedimentation tank 1, so that the cleaning of the filter screen 6 and the mixing of sewage and flocculant are carried out simultaneously, thereby ensuring that a sufficient amount of flocculant can fully contact the sewage. Through the flocculant in the sedimentation tank 1, the introduced sewage can be treated by flocculation and sedimentation. After flocculation and sedimentation, it can be discharged from the sedimentation tank 1 through the connecting pipe 12 on the other side.

[0035] The two semi-circular receiving plates 7 can be manually cleaned after being pulled out by the sealing plug 71 from the engaging groove 72, so that the flocculating agent on the semi-circular receiving plate 7 can be manually cleaned.

[0036] Although the embodiments of the present application have been shown and described, it is to be understood that various changes and modifications can be made by those skilled in the art without departing from the spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
