[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] See also Figure 1 to Figure 3 In an embodiment of the utility model, an aeration mechanism for urban sewage treatment includes a rotating cover 1, which is connected to a fixed base 2 through a rotating component. The fixed base 2 is located below the rotating cover 1. The top surface of the rotating cover 1 is spherical and has a plurality of air holes 8. A multi-nozzle jet assembly that penetrates to the top of the fixed base 2 is installed at the bottom end of the fixed base 2. A plurality of baffles 10 are fixedly installed below the inner wall of the rotating cover 1, and the plurality of baffles 10 are equidistantly distributed in the circumferential direction.

[0017] In this embodiment: first, the device is connected to the output end of the aeration pipe. During aeration, the Roots blower presses air into the aeration pipe and inputs it into the device through the aeration pipe. The air is ejected from the nozzle through the multi-nozzle jet assembly. The high-speed blown gas acts on the baffle 10. The baffle 10 is driven by the force to drive the rotating cover 1 to rotate. At the same time, the air overflows outward through the air hole 8 after contacting the baffle 10. With the rotating rotating cover 1, the gas entering the aeration tank at this time overflows outward in a spiral shape, which can effectively increase the explosion range and thus improve the efficiency.

[0018] Please refer to Figure 1 , Figure 2 and Figure 3 The multi-nozzle jet assembly includes an air pipe 3 that passes through from the bottom of the fixed base 2 to the top of the fixed base 2, an external thread is provided at the bottom of the outer wall of the air pipe 3, and a retaining ring 4 is integrally formed on the outer wall of the air pipe 3 above the external thread. The multi-nozzle jet assembly also includes a connecting plate 7 integrally formed at the top of the air pipe 3, the inner cavity of the connecting plate 7 is connected to the inner cavity of the air pipe 3, and the connecting plate 7 is a hollow disc-shaped structure. The multi-nozzle jet assembly also includes an air nozzle 9, which passes through the inner cavity of the connecting plate 7 to the outside of the connecting plate 7, the air nozzle 9 is inclined, and a one-way valve is installed at the input end of the air nozzle 9.

[0019] In this embodiment: when connecting the device to the aeration pipe, first, a waterproof tape is wrapped around the outer wall of the aeration pipe, and then the air pipe 3 is docked with the threaded connector of the aeration pipe and rotated to connect until it is fully tightened. At this time, the bottom end of the retaining ring 4 is against the threaded connector of the aeration pipe, and a rubber sealing ring is provided at the bottom end of the retaining ring 4. At this time, the rubber sealing ring is deformed by force to seal the top of the connector of the aeration pipe to prevent sewage or tiny impurities from contacting the waterproof tape, thereby improving the waterproof sealing performance.

[0020] After the air enters the interior of the connecting plate 7 along the air pipe 3, the gas is output through multiple air nozzles 9. After being output through the air nozzles 9, the gas acts on the baffle 10, and the baffle 10 is driven by the force to drive the rotating cover 1 to rotate; the setting of the one-way valve can prevent sewage from flowing back into the interior of the connecting plate 7 during the aeration stop time.

[0021] Please refer to Figure 3 The rotating assembly includes a rotating groove 6 integrally formed on the top edge of the fixed base 2 and a rotating ring 5 integrally formed on the bottom of the rotating cover 1. The rotating ring 5 is rotatably connected to the inner wall of the rotating groove 6, and a dynamic sealing ring is installed on the outer wall of the rotating ring 5, and a static sealing ring is installed on the inner wall of the rotating groove 6, and the dynamic sealing ring is fitted with the static sealing ring.

[0022] In this embodiment, when the rotating cover 1 rotates, the rotating cover 1 drives the rotating ring 5 to rotate in the rotating groove 6. At this time, the dynamic seal ring rotates relative to the static seal ring. The dynamic seal ring and the static seal ring are both made of self-lubricating rubber material, which can reduce the rotational friction coefficient and reduce wear. The arrangement of the dynamic seal ring and the static seal ring can prevent air from overflowing from the two parts of the rotating component that are in contact, so that the air only overflows from the air hole 8.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
