[0002] Biological treatment is the core technology for all types of wastewater treatment. Biological treatment processes cannot function without the support of aeration systems, which are the core facilities for maintaining the activity of biological treatment microorganisms.

[0003] The biological aeration system includes components such as aeration branch pipes, aeration membrane sheets, and membrane support pipes. The purpose of aeration is to meet the metabolic oxygen requirements of microorganisms in the biological tank, while also agitating the activated sludge to ensure it remains suspended in the mixed liquor without settling. This facilitates the rapid adsorption and degradation of organic matter in the wastewater, thereby achieving the goal of purifying the water.

[0004] Although there are many types of aeration devices, in order to improve oxygen utilization, the aerators are usually installed at the bottom of the sewage tank. When the aerators malfunction, the only way to allow maintenance personnel to enter the bottom of the tank for repairs is to drain the water, which causes inconvenience to the maintenance of the aerators. Utility Model Content

[0005] In view of this, it is necessary to provide a liftable oxidation tank aeration device to solve the technical problem of inconvenient maintenance of existing aeration devices.

[0006] To achieve the above-mentioned technical objectives, the present invention provides a liftable oxidation tank aeration device, comprising:

[0007] Aeration main pipe, used to connect aeration equipment;

[0008] A horizontal pipe is connected to both sides of the main aeration pipe;

[0009] A plurality of aeration branch pipes are provided, each aeration branch pipe being spaced apart along the length of the sewage tank and connected to the horizontal pipe, and both ends of each aeration branch pipe extending along the width of the sewage tank and used for mounting on the sewage tank.

[0032] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0033] This utility model provides a liftable oxidation tank aeration device, which is used to aerate the sewage tank 60 and can be lifted relative to the sewage tank 60. Therefore, when the aeration device is being maintained, it can be taken out of the sewage tank 60 to facilitate maintenance and solve the technical problem of inconvenient maintenance of aeration devices in the prior art.

[0034] To achieve the above objectives, such as Figure 1 and 3As shown, the liftable oxidation tank aeration device provided by this utility model includes an aeration main pipe 10, a horizontal pipe 20, a plurality of aeration branch pipes 30, a plurality of vertical pipes 40, and a plurality of membrane pipes 50. The aeration main pipe 10 is used to connect aeration equipment; the horizontal pipes 20 are connected to both sides of the aeration main pipe 10; each aeration branch pipe 30 is spaced along the length direction of the sewage tank 60 and connected to the horizontal pipe 20, and both ends of each aeration branch pipe 30 extend along the width direction of the sewage tank 60 and are used to be installed in the sewage tank 60; the upper end of each vertical pipe 40 is connected to each aeration branch pipe 30, and the lower end of each vertical pipe 40 extends to the bottom of the sewage tank 60; each membrane pipe 50 is connected to the lower end of each vertical pipe 40.

[0035] Specifically, the aeration device comprises an aeration main pipe 10, horizontal pipes 20, several aeration branch pipes 30, several vertical pipes 40, and several membrane pipes 50. The aeration main pipe 10 is connected to aeration equipment. During aeration of the wastewater tank 60, the aeration equipment introduces oxygen into the aeration main pipe 10, thus achieving oxygen input. The horizontal pipes 20 are connected to both sides of the aeration main pipe 10, allowing oxygen from the aeration main pipe 10 to enter the horizontal pipes 20 on both sides. Each aeration branch pipe 30 is connected to the horizontal pipe 20, allowing oxygen from the horizontal pipe to further flow to each aeration branch pipe 30. The upper ends of each vertical pipe 40 are respectively connected to each aeration branch pipe 30, allowing oxygen from the aeration branch pipe 30 to enter... The oxygen flows into each vertical pipe 40 and then into the bottom of the sewage tank 60. Each membrane tube 50 is connected to each vertical pipe 40, allowing oxygen to be introduced into the bottom of the sewage tank 60, thus achieving aeration. Since both ends of each aeration branch pipe 30 extend along the width of the sewage tank 60 and can be installed in the sewage tank 60, the aeration device can be installed at the opening of the sewage tank 60 through the aeration branch pipe 30. This allows the aeration device to be lifted relative to the sewage tank 60. When performing maintenance work on the aeration device, it can be lifted and taken out of the sewage tank 60, thus facilitating the maintenance of the aeration device.

[0036] In this embodiment, further, such as Figure 1 and 3 As shown, the aeration main pipe 10 includes a fixed pipe 11 and a sliding pipe 12. The fixed pipe 11 is used to connect the aeration equipment, and the sliding pipe 12 is slidably connected to the fixed pipe 11. The horizontal pipe 20 is connected to the fixed pipe 11 and the sliding pipe 12. Specifically, by setting the fixed pipe 11 and the sliding pipe 12, the aeration main pipe 10 can be extended and retracted, thus allowing the spacing of the horizontal pipes 20 of the aeration device to be adjusted, so that the aeration device can be better adapted to the installation of sewage tanks 60 of different sizes.

[0037] In this embodiment, the sliding tube 12 is further detachably connected to the fixed tube 11. Specifically, the detachable connection between the sliding tube 12 and the fixed tube 11 allows the sliding tube 12 to be removed from the fixed tube 11 and stored when the aeration device on the side of the sliding tube 12 is not in use. Then, the fixed tube 11 can be sealed, allowing aeration to proceed through the aeration device on the side of the fixed tube 11, thus preventing damage to the aeration device on the side of the sliding tube 12.

[0038] In this embodiment, the horizontal pipe 20 extends in the width direction of the sewage tank 60, and can also be erected at the opening of the sewage tank 60.

[0039] In this embodiment, each aeration branch pipe 30 is further detachably connected to the horizontal pipe 20. Specifically, through the detachable connection between the aeration branch pipe 30 and the horizontal pipe 20, when the membrane tube 50 on one side of the aeration branch pipe 30 is blocked, the aeration branch pipe 30 can be disassembled and removed separately to facilitate maintenance of the corresponding membrane tube 50. Maintenance of the aeration branch pipe 30 can be carried out without stopping aeration in the sewage tank 60.

[0040] In this embodiment, further, such as Figure 1 and 3 As shown, the aeration device also includes several on / off valves 31, each of which is installed on each aeration branch pipe 30. Specifically, when disassembling the aeration branch pipe 30, the on / off valves 31 are first closed to block oxygen. Then, the aeration branch pipe 30 on the side to be repaired, along with its fixed vertical pipe 40 and membrane pipe 50, are disassembled as a whole. After that, the aeration branch pipe 30, its fixed vertical pipe 40, and membrane pipe 50 can be repaired individually, while the other aeration branch pipes 30 remain in normal operation. This allows the aeration branch pipes 30 to be repaired without stopping aeration in the sewage tank 60.

[0041] In this embodiment, further, such as Figure 1-3 As shown, the vertical pipe 40 includes a first vertical pipe 41 and a second vertical pipe 42. The first vertical pipe 41 is connected to the aeration branch pipe 30, and the second vertical pipe 42 is rotatably connected to the first vertical pipe 41. The membrane tube 50 is connected to the second vertical pipe 42. Specifically, by setting the first vertical pipe 41 and the rotatably connected second vertical pipe 42, the orientation of the membrane tube 50 can be adjusted by rotating the second vertical pipe 42, thereby achieving the adjustment of the aeration angle.

[0042] In this embodiment, further, such as Figure 1-3 As shown, an upper rotating disk 411 is provided at the end of the first vertical pipe 41, and the upper rotating disk 411 is provided with a rotation supply cavity. A lower rotating disk 421 is provided at the upper end of the second vertical pipe 42, and the lower rotating disk 421 is rotatably connected to the rotation supply cavity. Specifically, the lower rotating disk 421 is rotatably connected to the inner side of the upper rotating disk 411, which enables the second vertical pipe 42 to rotate stably around the first vertical pipe 41.

[0043] In this embodiment, the membrane tube 50 is further detachably connected to the vertical tube 40. Specifically, by being detachably connected to the vertical tube 40, the membrane tube 50 can be removed from the vertical tube 40 during urgent replacement or maintenance, thereby facilitating the replacement or maintenance of the membrane tube 50.

[0044] In this embodiment, further, such as Figure 1-3 As shown, the membrane tube 50 includes an adapter 51 and two branch pipes 52. The adapter 51 is connected to the lower end of the second vertical pipe 42, and the two branch pipes 52 are connected to both sides of the adapter 51. Specifically, during aeration, oxygen enters the adapter 51 from the vertical pipe 40, then flows through the adapter 51 to the two branch pipes 52, and finally aeration is achieved through the two branch pipes 52. The adapter 51 enables a detachable connection between the membrane tube 50 and the vertical pipe 40.

[0045] In this embodiment, further, such as Figure 1-3 As shown, adapter 51 has sleeves on both sides, and branch pipe 52 is locked to the sleeves by clamps 53. Specifically, by locking adapter 51 with clamps 53, branch pipe 52 and adapter 51 can be detachably fixed, thus facilitating the replacement and maintenance of branch pipe 52.

[0046] This utility model also provides a wastewater aeration system, such as Figure 3 As shown, the system includes a wastewater tank 60 and the liftable oxidation tank aeration device, which is installed in the wastewater tank 60 via an aeration main pipe 10, a horizontal pipe 20, and an aeration branch pipe 30.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
