It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application. All other embodiments obtained by those skilled in the art based on the embodiments provided in this application without inventive effort are within the scope of protection of this application.

[0027] Obviously, the following description is merely some examples or embodiments of this application. Those skilled in the art can apply this application to other similar scenarios without any inventive effort. Furthermore, it is understood that although the effort involved in such development may be complex and lengthy, for those skilled in the art related to the content disclosed in this application, any changes to design, manufacturing, or production based on the technical content disclosed in this application are merely conventional technical means and should not be construed as insufficient disclosure of the content of this application.

[0028] See Figures 1 to 5 A tubular aerator includes an aeration pipe, a first connector 1 and a second connector 2, wherein the first connector 1 and the second connector 2 are respectively provided with a first connecting part 3 and a second connecting part 4 for enabling the first connector 1 and the second connector 2 to be connected to each other.

[0029] The first end of the aeration pipe is connected to the first connector 1, and the second end of the aeration pipe is connected to the second connector 2;

[0030] And / or, several aeration pipes 5 are connected in series through the first connector 1 and the second connector 2.

[0031] The aeration pipe is 1-2 meters long, and its length can be adjusted according to actual needs. The first connector 1 and the second connector 2 can be easily installed at both ends of the aeration pipe, and the connection between the first connector 1 and the second connector 2 is firm and reliable, and air leakage is not likely to occur. In addition, due to the design of the first connector 1 and the second connector 2, multiple aeration pipes can be easily connected in series to form a long strip aeration device, thus adapting to sewage treatment tanks of different sizes.

[0032] In practical implementation, an appropriate aeration pipe length and a suitable number of first connectors 1 and second connectors 2 can be selected according to actual needs to connect multiple aeration pipes in series to form a complete aeration device. During installation, simply connect the first connectors 1 and second connectors 2 to the two ends of the aeration pipe respectively, and then connect adjacent aeration pipes through the first connectors 1 and second connectors 2. This installation method is not only simple and convenient, but also greatly improves installation efficiency and reduces installation costs.

[0033] Since the aeration pipes are connected in series via the first connector 1 and the second connector 2, no additional ventilation trunk and branch pipes are required, thus greatly reducing the amount of pipe fittings and installation steps. Furthermore, because the length of the aeration pipes can be adjusted according to actual needs, they can flexibly adapt to wastewater treatment tanks of different sizes, improving the applicability and flexibility of the aerator.

[0034] In this utility model of tubular aerator, the first end of the aeration pipe is connected to the first connector 1, and the second end of the aeration pipe is connected to the second connector 2; and the first connector 1 and the second connector 2 are respectively provided with a first connecting part 3 and a second connecting part 4 for enabling the first connector 1 and the second connector 2 to be connected to each other, so that several aeration pipes 5 can be connected in series through the first connector 1 and the second connector 2, thereby enabling each tubular aerator to be connected to each other, extending its use indefinitely, greatly reducing the amount of pipes used and installation steps, thus saving costs.

[0035] See Figure 3 In this embodiment, the first connector 1 includes a first connecting portion 3 and a first socket portion 6. The first socket portion 6 is used to connect to the first end of the aeration pipe, and the first connecting portion 3 is provided with a connector for engaging with the second connecting portion 4. The connection method between the first socket portion 6 and the aeration pipe is insertion; either the first socket portion 6 of the first connector 1 is inserted into the aeration pipe, or the aeration pipe is inserted into the first socket portion 6. In another preferred embodiment, the first socket portion 6 and the aeration pipe can also be connected by threads, clamps, or other means.

[0036] See Figure 4 In this embodiment, the second connector 2 includes a second connecting portion 4 and a second socket portion 7. The second socket portion 7 is used to connect to the second end of the aeration pipe, and the second connecting portion 4 is provided with a connector for engaging with the first connecting portion 3. The connection between the second socket portion 7 and the aeration pipe is a plug-in connection, which can be either inserting the second socket portion 7 of the second connector 2 into the aeration pipe or inserting the aeration pipe into the second socket portion 7. In another preferred embodiment, the second socket portion 7 and the aeration pipe can also be connected by threads, clamps, or other means.

[0037] By employing the design of the first connector 1 and the second connector 2, the connection of the aeration pipe becomes more flexible and diverse. It can be connected not only by plug-in connection but also by threaded connection, clamps, etc., thereby further improving the connection stability and reliability of the aerator. Furthermore, the first connector 1 and the second connector 2 are equipped with fasteners for secure connection with the aeration pipe, further ensuring the strong connection between the aeration pipe and the connector and avoiding air leakage caused by loose connection. Preferably, the fasteners are clips or clamps, etc., to firmly connect the aeration pipe to the first connector 1 and the second connector 2, thereby improving the stability and reliability of the connection. In specific implementation, appropriate fastener types and quantities can be selected according to actual needs to ensure a strong and reliable connection between the aeration pipe and the connector.

[0038] In this embodiment, the connectors on the first connecting part 3 and the second connecting part 4 are either threads or snap fasteners. Preferably, when the connector is a thread, the first connecting part 3 and the second connecting part 4 are respectively provided with internal threads and external threads, and the connection between the first connector 1 and the second connector 2 is achieved through the cooperation of the internal and external threads. When the connector is a snap fastener, the first connecting part 3 and the second connecting part 4 are respectively provided with snap fastener grooves and snap fastener protrusions, and the connection between the first connector 1 and the second connector 2 is achieved through the cooperation of the snap fastener grooves and snap fastener protrusions. This connection method is not only simple and convenient, but also provides a firm and reliable connection, and is less prone to air leakage.

[0039] In addition, to improve the aeration effect, the aeration pipe in this embodiment also includes an inner liner pipe 51 and an aeration membrane 52. The two ends of the inner liner pipe 51 are used to connect to the first connector 1 or the second connector 2, and the aeration membrane 52 wraps around the outside of the inner liner pipe 51. The aeration membrane 52 is made of a microporous material, possessing good air permeability and corrosion resistance, and can effectively disperse air into tiny bubbles, improving oxygen transfer efficiency. The aeration membrane 52 can be made of various materials, such as EPDM, silicone rubber, polyurethane rubber, and high-molecular-weight polyethylene. Simultaneously, clamps 8 are provided at both ends of the aeration pipe to fix the aeration membrane 52 to the inner liner pipe 51, preventing the aeration membrane 52 from falling off or being damaged during use.

[0040] In the actual implementation process, appropriate aeration membrane 52 materials and thicknesses, as well as an appropriate number of clamps 8, can be selected according to actual needs to ensure aeration effect and stability of aeration membrane 52. At the same time, for convenient installation and maintenance, several air outlets 9 can also be provided on the inner lining pipe 51 of the aeration pipe. The setting of air outlets 9 can be adjusted according to actual needs to improve aeration effect and adapt to sewage treatment tanks of different sizes.

[0041] In summary, the tubular aerator of this invention, through the design of the first connector 1 and the second connector 2, allows multiple aeration pipes to be easily connected in series to form a long, narrow aeration device, thus adapting to wastewater treatment tanks of different sizes. Furthermore, the connection methods for the aeration pipes are flexible and diverse, including not only plug-in connections but also threaded connections, clamps, etc., further improving the connection stability and reliability of the aerator.

[0042] In actual operation, air enters the tubular aerator from either end of the connector and enters the inner liner tube 51. The inner liner tube 51 has air outlet holes 9. Preferably, the air outlet holes 9 are set at both ends of the inner liner tube 51, with at least 4 air outlet holes 9 at each end. Air can pass through the air outlet holes 9 of the inner liner tube 51 and enter the aeration membrane 52. The aeration membrane 52 is attached to the outside of the inner liner tube 51 and has uniform small holes. When air passes through the air outlet holes 9 of the inner liner tube 51, the aeration membrane 52 opens. The aeration membrane 52 has uniform small holes, and the air diffuses evenly from the small holes on the surface of the aeration membrane 52.
