Technical Field

[0001] This utility model relates to the field of sewage treatment equipment technology, and more specifically, to an aeration device for a sewage treatment regulating tank. Background Technology

[0002] In the operation of a wastewater treatment plant, the equalization tank plays an important role in regulating water quality and quantity. However, traditional equalization tanks have some problems, such as sludge sedimentation and uneven water quality, which affect the efficiency and stability of the entire wastewater treatment system. To improve the performance of the equalization tank, installing aeration devices has become an effective technical improvement measure.

[0003] In existing technology, aeration devices generally consist of a main air supply pipe, an air supply branch pipe, and an aeration pipe. After a period of use, the aeration pipe needs to be replaced due to blockage or damage. When replacing it, since the aeration pipe is below the water surface, the water in the equalization tank needs to be drained first before it can be replaced. In addition, it requires personnel to enter the equalization tank, which poses certain safety hazards and also affects the replacement efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problem of inconvenient replacement of aeration pipes, and to design an aeration device for a sewage treatment regulating tank.

[0005] To achieve the above objectives, the technical solution of this utility model is an aeration device for a sewage treatment equalization tank, comprising a main air supply pipeline installed at the lower end of the equalization tank, an air inlet pipe connected to the inlet end of the main air supply pipeline, a regulating valve installed at the inlet end of the air inlet pipe, multiple connecting pipes rotatably installed on the main air supply pipeline, a limit frame installed on the main air supply pipeline to limit the connecting pipes, an air supply branch pipe installed at one end of the connecting pipe, multiple aeration pipes installed on the air supply branch pipe, and the air supply branch pipe being able to be installed and removed from the connecting pipe.

[0006] Furthermore, the connecting pipe includes a flexible pipe installed on the main gas pipeline, and the outlet end of the flexible pipe is connected to a rigid pipe.

[0007] Furthermore, the limiting frame includes limiting rods installed at both ends of the rigid pipe, and limiting sleeves are provided on both sides of the limiting rods. One end of the limiting rod extends into the limiting sleeve, and the limiting sleeve is installed on the main gas transmission pipeline by a fixing rod.

[0008] Furthermore, the outlet end of the rigid pipe is provided with an external thread, the inlet end of the gas transmission branch pipe is provided with an internal thread, the inlet end of the gas transmission branch pipe and the outlet end of the rigid pipe are connected by threads, a sealing ring is installed at the connection position of the gas transmission branch pipe and the rigid pipe, and the gas transmission branch pipe can be easily installed and removed by rotating it. A first connecting rope is installed at the end of the gas transmission branch pipe away from the rigid pipe, and a second connecting rope is installed at one end of the rigid pipe. One end of the first connecting rope and the second connecting rope extends to the upper end of the regulating pool.

[0009] Furthermore, a removable cover is installed at the end of the gas supply branch pipe away from the rigid pipe, a movable piston is placed inside the gas supply branch pipe, and a third connecting rope is installed at one end of the movable piston.

[0010] The beneficial effects of this utility model are as follows: Since the connecting pipe is rotatable, when the aeration pipe needs to be replaced, the air supply branch pipe can be pulled to one side, and then the air supply branch pipe can be erected and removed from the connecting pipe for replacement. There is no need to drain the water in the regulating tank, which facilitates replacement and improves replacement efficiency. Attached Figure Description

[0014] This utility model provides, for example Figure 1-4 The aeration device for a wastewater treatment equalization tank shown includes a main air supply pipe 1, which is installed at the lower end of the equalization tank. An air inlet pipe 2 is connected to the inlet end of the main air supply pipe 1, and a regulating valve 3 is installed at the inlet end of the air inlet pipe 2. Multiple connecting pipes 4 are rotatably installed on the main air supply pipe 1. A limit frame 5 is installed on the main air supply pipe 1 to limit the connecting pipes 4. An air supply branch pipe 6 is installed at one end of the connecting pipe 4, and multiple aeration pipes 7 are installed on the air supply branch pipe 6. The air supply branch pipe 6 can be installed and removed from the connecting pipe 4.

[0015] The process of replacing the aeration pipe using this device is as follows: After the device is installed, the air intake speed can be adjusted by controlling the opening size of the regulating valve 3, allowing air to pass through the air intake pipe 2, the main air supply pipe 1, and the connecting pipe 4 into the air supply branch pipe 6, and then be discharged through the aeration pipe 7. When it is necessary to replace a certain aeration pipe 7 after a period of use, the operator uses tools to pull up the air supply branch pipe 6, which allows the connecting pipe 4 to rotate. The limiting bracket 5 can limit the rotation position of the connecting pipe 4, ensuring the rotation position of the air supply branch pipe 6. When the air supply branch pipe 6 rotates to a vertical position, the outlet end of the connecting pipe 4 remains in a vertical position. Then, the air supply branch pipe 6 is removed from the connecting pipe 4, making it easy to replace the aeration pipe 7.

[0016] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 2 The connecting pipe 4 includes a flexible pipe 8 installed on the main gas pipeline 1. The outlet end of the flexible pipe 8 is connected to a rigid pipe 9. The flexible pipe 8 can easily rotate the rigid pipe 9 to a vertical position, and the rigid pipe 8 can easily connect the gas branch pipe 6.

[0017] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 2The limiting frame 5 includes limiting rods 10 installed at both ends of the rigid pipe 9. Limiting sleeves 11 are provided on both sides of the limiting rods 10. One end of the limiting rod 10 extends into the limiting sleeve 11. The limiting sleeve 11 is installed on the main gas transmission pipe 1 through the fixing rod 12. The limiting sleeve 11 can limit the limiting rod 10, thereby limiting the rotation of the rigid pipe 9.

[0018] Refer to the instruction manual appendix Figure 3 The rigid pipe 9 has an external thread at its outlet end and an internal thread at its inlet end. The inlet end of the gas branch pipe 6 and the outlet end of the rigid pipe 9 are connected by threads. A sealing ring 13 is installed at the connection point between the gas branch pipe 6 and the rigid pipe 9. The gas branch pipe 6 can be easily installed and removed by rotating it. A first connecting rope 14 is installed at the end of the gas branch pipe 6 away from the rigid pipe 9, and a second connecting rope 15 is installed at one end of the rigid pipe 9. One end of the first connecting rope 14 and the second connecting rope 15 extends into… At the upper end of the equalization tank, when it is necessary to replace the aeration pipe 7, first pull the air supply branch pipe 6 and the rigid pipe 9 with the first connecting rope 14 and the second connecting rope 15 to make them vertical. Then rotate the air supply branch pipe 6 to separate it from the rigid pipe 9. After replacing the aeration pipe 7, extend the lower end of the air supply branch pipe 6 into the rigid pipe 9. Then reverse the air supply branch pipe 6 to reconnect it with the rigid pipe 9. The sealing ring 13 can prevent sewage from entering the pipe.

[0019] Refer to the instruction manual appendix Figure 4 A removable cover 16 is installed at the end of the gas supply branch pipe 6 away from the rigid pipe 9. A movable piston 17 is placed inside the gas supply branch pipe 6. A third connecting rope 18 is installed at the outer end of the movable piston 17. After the gas supply branch pipe 6 is rotated to a vertical position, the cover 16 is opened. The operator uses a rigid rod to move the movable piston 17 downward and into the rigid pipe 9. This makes it easier to remove the gas supply branch pipe 6 and grab the third connecting rope 18. When installing the new gas supply branch pipe 6 on the vertical pipe 9, the third connecting rope 18 is first passed through the gas supply branch pipe 6, and then the new gas supply branch pipe 6 is connected to the vertical pipe 9. Then, the movable piston 17 is pulled out of the rigid pipe 9 through the third connecting rope 18, which can reduce the amount of sewage entering the pipe. Finally, the gas supply pipe 6 is placed into the lower end of the regulating tank.
