The purpose of urban sewage treatment is to protect water resources, prevent water pollution, improve urban environmental quality, and protect people's health. At the same time, urban sewage treatment can also reduce fossil fuel consumption and greenhouse gas emissions, achieving the dual goals of resource conservation and environmental protection.

[0003] At present, during the use of the urban sewage sedimentation and filtration device in the prior art, since the urban sewage carries a large amount of impurities, it needs to be precipitated and filtered. The drain outlet of the existing device is generally provided with a filter screen, but after long-term use, some impurities may adhere to the surface of the filter screen, resulting in a decrease in drainage volume and possibly affecting the filtration effect; and after some existing devices filter the sewage, the impurities will be deposited at the bottom of the device, which is not convenient for directly discharging the impurities, making it time-consuming and laborious for workers to clean up. Therefore, there is an urgent need for an urban sewage sedimentation and filtration device to solve the above problems. Utility Model Content

[0026] The filtering structure 2 includes a filtering tube 21, and one end of the filtering tube 21 is connected to the inside of one side of the sedimentation cylinder 11. The filtering structure 2 is used for filtering sewage. The filtering structure 2 also includes a fixing seat 22, and the fixing seat 22 is fixedly connected to the outer surface of the upper end of one end of the filtering tube 21, and a motor 23 is installed inside the fixing seat 22. A worm 24 is fixedly connected to the output end of the motor 23, and a worm wheel 25 is meshingly connected to the outer surface of the worm 24, and a fixing frame 26 is connected to the bearing on the outer surface of the middle position of the worm wheel 25. The setting of the fixing seat 22 can make the motor 23 more stable when in use, and can prevent the vibration generated by the motor 23 when in use from directly acting on the upper surface of the filtering tube 21. This design can play a certain protective role on the filtering tube 21 and can extend the service life of the filtering tube 21.

[0027] The outer surface of the worm 24 meshes with the outer surface of the other end of the worm wheel 25, so that the worm 24 can drive the worm wheel 25 to rotate when rotating. The bearing of the worm wheel 25 is connected to the inside of the fixed frame 26, so that the worm wheel 25 will not be displaced when rotating, making the worm wheel 25 more stable when rotating.

[0029] Embodiment 2

[0030] like Figure 5 and Figure 6As shown, the present embodiment further proposes: a collecting structure 3, the collecting structure 3 includes a collecting barrel 31, and the outer surface of the upper end of the collecting barrel 31 is fixedly connected to the outer surface of the lower end of the connecting plate 12, the collecting structure 3 is used for collecting impurities, the collecting structure 3 also includes a sealing cover 32, and the sealing cover 32 is inserted into the interior of the lower end of the collecting barrel 31, and the outer surfaces of both ends of the sealing cover 32 are fixedly connected to the limiting blocks 33, the interior of the sealing cover 32 is inserted with a moving block 34, and the moving block 34 is provided with two groups, the diameter size of the sealing cover 32 is adapted to the diameter size of the interior of the lower end of the collecting barrel 31, so that the sealing cover 32 can block the interior of the lower end of the collecting barrel 31 to prevent the impurities in the collecting barrel 31 from flowing out,

[0031] The sizes of the two groups of limit blocks 33 are adapted to the sizes of the two sides of the lower end of the collecting tube 31. This design can prevent the sealing cover 32 from rotating inside the collecting tube 31 and limit the sealing cover 32. The surfaces on one side of the two groups of moving blocks 34 are in contact with the lower surface inside the collecting tube 31. This design can prevent the sealing cover 32 from downwardly detaching from the inside of the collecting tube 31, and the height of the moving blocks 34 is equal to the radius of the sealing cover 32. This design makes it possible for the surfaces of the two groups of moving blocks 34 at opposite ends to fit together and be adapted to the diameter of the sealing cover 32. At this time, the surfaces on one side of the two groups of moving blocks 34 are completely detached from the lower surface inside the collecting tube 31.

[0032] The surfaces of one side of the two groups of moving blocks 34 are respectively fixedly connected with moving columns 35, and a rotating disk 36 is sleeved on the outer surface of the middle position of the two groups of moving columns 35, and the surface of one side of the rotating disk 36 is in contact with the surface of one side of the sealing cover 32, and a sliding groove is provided inside the rotating disk 36. The diameter size of the middle position of the two groups of moving columns 35 is matched with the size of the sliding groove, and a blocking block is provided at one end of the two groups of moving columns 35, and the surface of one end of the blocking block is in contact with the surface of the other side of the rotating disk 36.

This design fixes the position of the sealing cover 32.

[0033] Working principle: When the equipment is in use, the equipment is placed in a suitable position through the four groups of supporting legs 13, and the urban sewage to be filtered is poured into the interior of the sedimentation cylinder 11. The impurities in the sewage fall into the interior of the connecting plate 12 due to gravity, and then are collected in the interior of the collecting cylinder 31 through the lower end of the connecting plate 12. The precipitated sewage flows into the interior of the filter tube 21 through the circular holes inside one side of the sedimentation cylinder 11. The impurities in the sewage are blocked by the filter screen 28. The motor 23 is powered by an external power supply, and the motor 23 is started. The output end of the motor 23 drives the worm 24 to rotate, and then the worm 24 drives the worm gear 25 to rotate inside the fixing frame 26. At the same time, the worm gear 25 drives the cleaning brush 27 to rotate synchronously, and then one side of the cleaning brush 27 cleans the surface of one side of the filter screen 28. Finally, the filtered sewage is discharged through the other end of the filter tube 21.

[0034] When it is necessary to clean the impurities inside the collecting barrel 31, first empty the sewage inside the sedimentation barrel 11, rotate the rotating disk 36, and prevent the sealing cover 32 from rotating by setting two sets of limit blocks 33, then move the two sets of movable columns 35, and at the same time drive the two sets of movable blocks 34 to approach each other. When the surfaces of the opposite ends of the two sets of movable blocks 34 are in contact, the surfaces on one side of the two sets of movable blocks 34 are completely separated from the lower surface inside the collecting barrel 31. At this time, remove the sealing cover 32 so that the sealing cover 32 is separated from the interior of the lower end of the collecting barrel 31, and then the impurities inside the collecting barrel 31 are automatically discharged downward due to gravity. The above is the entire working principle of the utility model.
