Description

Aeration device for sewage treatment

[0001] This patent application claims priority to Chinese patent application No. CN 202410244104.0 filed on March 4, 2024. The disclosure of the prior application is incorporated herein by reference in its entirety. Technical Field

[0002] The present application belongs to the technical field of sewage treatment, and specifically relates to an aeration device for sewage treatment. Background Art

[0003] Daily production and daily life require a large amount of water resources, which generates a large amount of sewage. Some sewage contains many harmful substances and cannot be discharged directly. In order to alleviate the shortage of water resources on the earth and protect the ecological environment, sewage needs to be treated before discharge. The sewage treatment process requires the decomposition and removal of pollutants in the sewage.

[0004] In the prior art, a large amount of dissolved oxygen is required to remove pollutants from sewage, so aeration is required. Aeration refers to the process of forcibly transferring oxygen from the air to the liquid, with the aim of obtaining sufficient dissolved oxygen. The commonly used aeration method is usually blower aeration, which refers to using an aerator to pump air into the aeration head, which then diffuses into the water to form bubbles, and dissolves oxygen in water at the gas-liquid interface. However, this method causes deep sewage to rise slowly and cannot quickly come into contact with oxygen in the air, resulting in low oxygen binding efficiency, affecting the aeration speed and poor practicality.

[0061] In one embodiment, the transmission assembly 6 can adopt a structure as shown in Figures 2 and 3.

The spacing between the two first push plates 22 is defined as a first direction, and a direction perpendicular and horizontal to the first direction is defined as a second direction. Two first movable plates 32 are provided, each positioned outside the aeration tank 1 along the first direction. The first movable plates 32 are connected to the first push plates 22 via two first slide bars 20 slidably mounted on the aeration tank 1. The elastic member is mounted on the first slide bars 20 and is located outside the aeration tank 1, providing a continuous elastic force to push the first movable plates 32, ensuring that the first movable plates 32 maintain a tendency to move away from the aeration tank 1. Two follower rods 24 are provided, each rotatably mounted on the support frame 2 and positioned on either side of the support tube 11 along the first direction. The two follower rods 24 are dynamically connected to the support tube 11 via a first transmission member 26. Two cams 25 are provided, each fixed to the two follower rods 24, with their axes arranged vertically. Two adjustment plates 23 are provided, one corresponding to each cam 25. Each adjustment plate 23 is positioned between a corresponding cam 25 and the support tube 11, abutting against the outer edge of the cam 25. The two adjustment plates 23 are connected to the two first movable plates 32 via two connecting frames 21. Two sets of connecting components are provided, one set located on either side of the support tube 11 along the first direction. Each set of connecting components includes a plurality of connecting rods 27 spaced apart along the second direction. Each connecting rod 27 has one end rotatably connected to the adjustment plate 23 and the other end rotatably connected to the lifting plate 14, thereby pulling the lifting plate 14 back and forth in the vertical direction. Two second push plates 28 are provided, and the two second push plates 28 are spaced apart along the second direction in the aeration tank 1. Two second movable plates 30 are provided, and the two second movable plates 30 are respectively provided outside the aeration tank 1 along the second direction. The second movable plates 30 are connected to the second push plates 28 via two second sliding rods 29 slidably provided on the aeration tank 1.

[0067] It should be noted that each first push plate 22 and each second push plate 28 together form a liquid pushing portion.

The wheel diameter of the first pulley disposed on the support tube 11 is larger than the wheel diameter of the first pulley disposed on the driven rod 24. Both driven rods 24 are fixedly connected to a cam 25, and an adjustment plate 23 is disposed between the cam 25 and the support tube 11. A connecting frame 21 is fixedly connected between the adjustment plate 23 and the first movable plate 32, and an elastic member is fixedly connected between the first movable plate 32 and the aeration tank 1.

The support tube 11 rotates the driven rods 24 on both sides via the first pulley and the first belt. The driven rods 24 rotate the cam 25, which, in conjunction with the spring disposed between the first movable plate 32 and the aeration tank 1, achieves reciprocating motion of the first movable plate 32. The first movable plate 32 reciprocates the first push plate 22 via the first slide bar 20. Simultaneously, the first movable plate 32 reciprocates the second movable plate 30 via the connecting assembly 31. The second movable plate 30, in conjunction with the second slide bar 29, achieves reciprocating motion of the second push plate 28. The movement of the adjustment plate 23 also cooperates with the connecting rod 27 to achieve up and down reciprocating motion of the lifting plate 14. The lifting plate 14 drives the fixed tube 15 to move, allowing oxygen to effectively contact the deep sewage. The push assembly 7, in conjunction with the transmission assembly 6, enables reciprocating motion of the first and second push plates 22, 28. The first and second push plates 22, 28 cooperate to drive sewage from the edge of the aeration tank 1 toward the center, thereby avoiding dead zones during aeration and ensuring comprehensive aeration.

By providing a connecting assembly 31, the movement of the first movable plate 32 drives the first piston to move within the first sliding cavity 33. The movement of the second piston within the second sliding cavity 35 is achieved through the ventilation groove 36. The second piston cooperates with the second push rod to achieve the movement of the second movable plate 30. When the first piston enters the first sliding cavity 33, the second piston moves outward from the second sliding cavity 35. Conversely, when the first piston moves outward from the first sliding cavity 33, the second piston moves into the second sliding cavity 35.
