DETAILED DESCRIPTION

[0016] 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.

[0017] See also Figure 1-2 A gas collecting and aerating device comprises: a gas collecting pipe 1, a rectangular connecting pipe 2, an aeration plate 3 and an air pump group 4, an air inlet branch pipe 5 is arranged between the air pump group 4 and the gas collecting pipe 1, both ends of the gas collecting pipe 1 are connected with gas separation components, the gas separation components are connected with the rectangular connecting pipe 2, the aeration plate 3 is installed on the rectangular connecting pipe 2, the surface of the rectangular connecting pipe 2 is connected with a flushing outlet pipe 7, and the surface of the flushing outlet pipe 7 is provided with a first regulating valve 8.

[0018] In a specific embodiment, the air pump group 4 is composed of 4 air pump groups 4, the number of the air intake branch pipes 5 is 2, the air intake branch pipes 5 are connected to the air outlet end of the air pump, and the air collecting pipe 1 is connected to the air intake pipe.

[0019] A straight tee 9 is installed at the bottom of the aeration plate 3 , and the straight tee 9 is installed on the surface of the rectangular connecting pipe 2 .

[0020] The gas distribution assembly includes a gas distribution pipe 61 and a second regulating valve 62 . One end of the gas distribution pipe 61 is connected to the surface of the gas collecting pipe 1 , and the other end of the gas distribution pipe 61 is connected to the surface of the rectangular connecting pipe 2 . The second regulating valve 62 is installed on the surface of the gas distribution pipe 61 .

[0021] A pressure sensor 10 is provided on the surface of the intake branch pipe 5 .

[0022] During normal operation, the air pump is turned on and the first regulating valve 8 is opened; the gas is first collected into the gas collecting pipe 1 through the two-way air inlet branch pipe 5, and then divided into the gas distribution pipe 61, and then the gas-consuming unit is oxygenated and aerated through the aeration plate 3, and the gas distribution volume of the two gas-consuming units is adjusted by the second regulating valve 62; there will be a certain amount of liquid inside the gas distribution pipe 61 and the aeration plate 3 before the air pump is turned on. When aeration starts, as the air pressure increases, the liquid inside will flow along the flushing outlet pipe 7 to the flushing outlet pipe 7, and finally be discharged out of the flushing outlet pipe 7. When no liquid flows out of the flushing outlet pipe 7, the first regulating valve 8 can be manually closed and kept closed during normal operation.

[0023] After running for a certain period of time, the value change of the pressure sensor 10 can be observed. When the pressure suddenly decreases, it is necessary to check whether the air pump is working normally and whether there is any leakage in the aeration system; when the pressure suddenly increases, it is necessary to check whether the system is blocked. The aeration plate 3 is located in the sewage for a long time, so blockage often occurs in the aeration plate 3.

[0024] When the aeration plate 3 is blocked, the air supply pipeline can be flushed and cleaned with a large amount of air. The specific implementation method is to open the first regulating valve 8 on the side that needs to be flushed, fully open or fine-tune the second regulating valve 62 on the same side, and close the second regulating valve 62 on the other side. After flushing with a large amount of air for 10 to 30 minutes, slowly open the closed second regulating valve 62, close the first regulating valve 8, and resume operation. Similarly, flush the pipeline on the other side, so as to achieve high-pressure flushing and cleaning of the aeration pipeline and the aeration plate 3.

[0025] According to the operation status of the aeration device, the pipeline can be restoratively cleaned once every 3 to 6 months. The specific implementation method is to close the air pump group 4 and then open the first regulating valve 8. After stopping the water intake, soak for 1 to 3 hours, then open the air pump group 4 to flush the pipeline, observe the water outlet of the flushing outlet pipe 7, and slowly close the first regulating valve 8 when there are fewer impurities, and resume operation, so as to achieve thorough restorative cleaning of the regular aeration pipeline and the aeration plate 3.
