[0002] Urban sewage refers to the general term for water discharged into the urban sewage system, which includes industrial production water, rainwater and domestic water. The sewage system in the city generally transports the sewage to the sewage treatment station through the drain pipes inside for treatment.

[0003] Urban sewage is generally treated in the sewage treatment station through a multi-stage sewage treatment device. The multi-stage sewage treatment device first needs to perform primary sedimentation on the sewage to remove large particulate impurities and sediment in the sewage, then perform secondary treatment on the sewage by adding chemical agents to flocculate some harmful substances inside the sewage, filter it, and finally perform tertiary treatment by using microorganisms to treat the organic matter inside the sewage, and finally discharge it into the river.

[0004] However, the large particulate impurities and sediment after sedimentation in the existing multi-stage sewage treatment device are not convenient to take out, so that after a period of sewage treatment, the sedimentation chamber needs to be drained, and the sedimented large particulate impurities and sediment are pumped out, resulting in a reduction in the sedimentation treatment efficiency of the sewage, and thus affecting the overall treatment efficiency.

Activity plates 13 are arranged on the outside of the rotating heads 12. Rotating grooves are correspondingly arranged in the transmission groove 8 for the activity plates 13. The activity plates 13 are all located in the rotating grooves. Through the semi-circular setting of the upper ends of the rotating heads 12, large particle impurities and sediment deposition at the upper ends of the rotating heads 12 can be avoided. Embodiment

[0036] On the basis of Embodiment 2, sludge outlets 14 are arranged inside the rotating heads 12. The bottoms of the sludge outlets 14 all penetrate through the rotating heads 12. Multiple groups of sludge dropping grooves 15 are equidistantly arranged at the upper ends of the sludge outlets 14. The bottoms of the sludge dropping grooves 15 all communicate with the sludge outlets 14. Recovery grooves 16 are arranged on the inner sides of the upper ends of the sludge dropping grooves 15.

The outsides of the scrapers 18 all penetrate through the covering grooves 17 and extend to the outside. Through the arranged recovery grooves 16, the scrapers 18 can be conveniently stored. Embodiment

[0037] On the basis of Embodiment 3, the rotating plate 19 is set as a disc structure. The rotating plate 19 is movably arranged inside the upper end of the rotating head 12. Three groups of extrusion grooves 20 are arranged at the bottom of the rotating plate 19 corresponding to the scrapers 18. The extrusion grooves 20 are set as arc-shaped grooves.

[0038] In use, first connect the mud suction head 6 to an external mud suction pump, then start the first servo motor 9. The first servo motor 9 drives the belt 11 to rotate through the transmission wheel 10. The belt 11 drives the rotating head 12 to rotate through the socket connection with the rotating head 12. The rotating head 12 pushes the scraper 18 to rotate. The scraper 18 scrapes the large-particle impurities and sediment at the upper end of the partition plate 4 into the covering groove 17. The large-particle impurities and sediment fall through the mud falling groove 15 into the inside of the mud outlet 14, and finally fall to the bottom of the sedimentation chamber 2 through the opening at the bottom of the mud outlet 14. When there is a large accumulation of large-particle impurities and sediment at the bottom of the sedimentation chamber 2, start the second servo motor 22. The second servo motor 22 drives the rotating plate 19 to rotate through the fixed connection with the rotating plate 19. The rotating plate 19 squeezes the extrusion block 21 through the side wall of the bottom extrusion groove 20, so that the extrusion block 21 drives the scraper 18 to move into the recovery groove 16. When the scraper 18 completely enters the inside of the recovery groove 16, the folding plate outside the scraper 18 fits with the covering groove 17 to block the mud falling groove 15, preventing the sewage from becoming turbid again due to excessive noise during the pumping of large-particle impurities and sediment at the bottom of the sedimentation chamber 2. Finally, start the external mud suction pump, and pump the large-particle impurities and sediment at the bottom of the sedimentation chamber 2 through the mud suction head 6, avoiding pumping the sedimentation chamber 2 dry for the transfer of large-particle impurities and sediment, and improving the overall treatment efficiency.

[0039] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
