Specifically, in the sewage treatment process, the wastewater of industrial production or urban life is pumped into sewage pool, and oxygen required in the process of microbial degradation is realized by aeration, and ecological sludge in sewage pool is agitated by aeration, and microorganisms mainly reproduce in ecological sludge, and the ecological sludge agitated by airflow can fully interact with sewage, and sludge can adsorb polluting substances in sewage.

[0003] Therefore, aeration treatment is a crucial process step in the current sewage treatment process.

[0004] The aeration device currently matched with sewage is a fixedly installed aeration pipe structure at the bottom of sewage pool, and in order to fully provide aeration gas, laying surface needs to be increased, which has the disadvantages that because the aeration gas is vertically applied to sewage from the bottom of sewage pool, the aeration radiation coverage is relatively narrow, therefore, the aeration coverage is improved by increasing the laying surface, which undoubtedly increases the cost of pipeline laying.

[0005] And the fixedly installed aeration pipe at the bottom of sewage pool is easily blocked by sludge, and the aeration pipe is seriously blocked due to the burial and blockage of a large amount of sludge settled in the process of sewage degradation. Therefore, it is obvious that the aeration pipe laid horizontally needs to be cleaned frequently, and cleaning undoubtedly increases the amount of sewage. Frequent cleaning increases the workload of sewage treatment and the use of clean water resources.

[0006] In the case of serious blockage of aeration pipe, cleaning is relatively troublesome. And once the aeration pipe installed at the bottom of pool is buried by sludge, it is very difficult to clean. INVENTION CONTENTS

[0040] Example 1

[0041] like Figures 1-4 As shown, an aeration pipe includes an annular aeration main pipe 1 (the annular aeration main pipe 1 has the following shape: it includes straight pipe sections symmetrically arranged on both sides, and the two ends of the straight pipe sections are integrally formed arc-shaped sections), and the rear end of the annular aeration main pipe 1 is connected to an air inlet pipe.

[0042] The top and bottom of the annular aeration main pipe 1 are respectively connected to several cage aeration units 3. During the aeration process, the cage aeration units 3 aerate gas.

[0043] The structure of the cage aeration unit 3 is as follows: the cage aeration unit 3 includes a cage-shaped aeration pipe structure, which includes several annularly distributed arc-shaped aeration pipes 33; several aeration holes 331 are opened on the arc-shaped aeration pipes 33.

[0044] Specifically, the cage aeration unit 3 also includes an annular pipe 31 connecting pipes respectively connected to one end of the arc-shaped aeration pipe 33, and the cage aeration unit 3 also includes an aeration seat 32 (aeration seat 32) respectively connected to the other end of the arc-shaped aeration pipe 33; the aeration seat 32 is connected to the annular aeration main pipe 1 through the connecting pipe 321.

[0045] The bottom of the aeration seat 32 is connected to a through pipe, which is connected to the connecting pipe 321 via a pipe flange assembly.

[0046] The aforementioned aeration seat 32, annular pipe 31, and arc-shaped aeration pipe 33 are made of plastic (specifically PVC, designed to reduce weight and facilitate the flipping of the float after its volume changes). According to existing methods, the arc-shaped aeration pipe 33 is welded and fixed to the corresponding through holes on the aeration seat 32 and the annular aeration main pipe 1 using a heat welding method.

[0047] During the aeration process, the aeration gas first passes through the annular aeration main pipe 1 and is then distributed to the cage aeration unit 3, which is connected vertically, for aeration.

[0048] Because the cage aeration unit 3 adopts a cage structure design, during operation, the aeration of the cage aeration unit 3 acts as a radiation unit, and the aerated gas radiates into the sewage. Because the cage aeration unit 3 is arranged in upper and lower layers, this method achieves upper and lower layer aeration treatment of the sewage tank.

[0049] The ecological mud that has settled at the bottom is agitated by airflow and then suspended, where it is further agitated by the upper cage aeration unit 3. This method not only enhances the aeration effect but also increases the coverage area of ​​the aeration radiation.

[0050] Example 2

[0051] like Figures 1-4 As shown, this embodiment, based on the structure of embodiment 1, further adjusts the direction of the aeration airflow to fully cover the wastewater tank with gas and remove sludge adhering to the cage aeration unit 3. The aeration pipe also includes an air flotation angle adjustment mechanism.

[0052] The angle of the annular aeration main pipe 1-cage aeration unit 3 is adjusted by the air flotation angle adjustment mechanism, thereby changing the radiation direction of the aeration airflow. At the same time, during the angle adjustment process, the annular aeration main pipe 1-cage aeration unit 3 is turned over in the sewage, thereby using the sewage to clean the attached sludge.

[0053] Specifically, the air flotation angle adjustment mechanism includes a float structure installed on the air inlet pipe. The other end of the annular aeration main pipe 1 is fixedly connected to a hinge structure. The float structure includes a pump pipe 52 connected to the air inlet pipe 2. The air outlet end of the pump pipe 52 is equipped with a balloon 51 (the balloon 51 is a conventional air balloon disclosed in the prior art, such as a balloon made of rubber). After pumping air, the balloon 51 expands and the buoyancy increases.

[0054] Specifically, the balloon 51 is connected to an exhaust pipe 53; valves are respectively installed and connected to the pump pipe 52, the exhaust pipe 53, and the air inlet pipe 2. Specifically, a first valve 521 is installed and connected to the pump pipe 52, a second valve 531 is installed on the exhaust pipe 53, and a third valve 21 is installed on the air inlet pipe 2. The third valve 21 is used to control the air intake of the annular aeration main pipe 1. The first valve 521, the second valve 531, and the third valve 21 are all solenoid valves.

[0055] Meanwhile, the hinge structure includes a hinge rod 41 fixedly connected to the annular aeration main pipe 1, and the hinge rod 41 is hinged to a hinge seat 42 (pins are fixedly connected to both sides of the hinge rod 41 and hinged to the hinge seat 42 respectively). The bottom of the hinge seat 42 is fixedly connected to a mounting frame 421, and the mounting frame 421 is fixedly installed at the bottom of the sewage tank (the bottom of the mounting frame 421 is a bottom mounting plate, which is anchored to the bottom of the tank by anchor bolts).

[0056] As is the case, the air inlet pipe 2 is connected to an aerator (not shown in the figure) via a flexible hose (the flexible hose makes it easy to flip the subsequent devices).

[0057] During operation, the third valve 21 and the second valve 531 are first closed (the first valve 521 is opened). At this time, the aeration gas is pumped into the balloon 51 from the air inlet pipe 2. After the balloon 51 expands, the buoyancy increases. At this time, the entire device rotates and adjusts its angle using the hinge structure as the hinge point. Subsequently, the first valve 521 is closed and the third valve 21 is opened for aeration.

[0058] During aeration, when it is necessary to change the aeration radiation angle, the first valve 521 is opened. At this time, as the gas inside the balloon 51 is pumped out, the volume of the balloon 51 decreases, and the buoyancy decreases. As the buoyancy continues to decrease, the entire device gradually sinks below the surface of the sewage tank until it reaches a position close to the bottom. This method achieves the change of the aeration radiation angle, and at the same time, the aforementioned agitation process cleans the attached sludge, preventing severe sludge accumulation.

[0059] In the above process, not only can the aeration angle be adjusted in a simple, flexible and easy-to-operate way, and the aeration device can be turned over to facilitate the cleaning of the attached mud, but the device also makes it less likely for the aeration to be blocked by the settled mud during the aeration process, which greatly improves the aeration treatment effect.

[0060] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
