Description

Technical Field

[0001] The invention relates to the field of sewage treatment equipment, and in particular to a sewage treatment aeration pipe structure. Background Art

[0002] In the sewage treatment process, aeration is a common treatment process. Its function is to provide sufficient oxygen by introducing gas (such as air, oxygen, etc.) into the sewage, promote the growth and metabolism of microorganisms, and thus promote the biochemical treatment of sewage.

[0003] For example, a sewage treatment aeration pipe structure with patent number CN219709255U has the following defects when in use, such as: it requires the air pressure input from the gas pipeline to be large enough to simultaneously push multiple groups of inner pipes to slide in the outer pipe while compressing the spring, so that the first air hole and the second air hole are aligned and connected to complete the subsequent ventilation work, but long-term exposure to high pressure of gas will undoubtedly cause indelible damage to the above-mentioned pipes, thereby affecting their safety and service life, and as long as the air pressure drops to a certain range, it cannot push the inner pipe to compress the spring at this time, which causes it to fail to smoothly perform the air guide work, thus affecting its scope of application. Summary of the invention

[0004] The purpose of the present invention is to provide an aeration pipe structure for sewage treatment.

[0007] A branch pipe with one end extending into the air supply pipe is arranged in the aeration pipe, wherein the other end of the branch pipe is sealed, and a rotating shaft fixed to the inner wall of the aeration pipe through a bearing is arranged on the sealed end of the branch pipe, and a plurality of air outlet holes II staggered with the air outlet holes I are arranged on the side wall of the branch pipe, wherein a gear ring is arranged at the end of the branch pipe located in the air supply pipe, and a rack meshing with multiple groups of gear rings is arranged at the bottom of the air supply pipe, and a base for fixing the rack is also arranged at the bottom of the air supply pipe, wherein a connecting rod extending to the outside of the air supply pipe is arranged at one end of the rack, and a vertical rod is arranged at the top of the connecting rod, and the vertical rod is driven by an electric push rod.

[0008] Preferably, the base is provided with a through hole for the rack to pass through, wherein the rack drives the branch pipe to rotate through the gear ring so that the air outlet hole II on its side wall can be connected with the corresponding air outlet hole I.

[0009] Preferably, a boss for fixing the bearing is provided on the inner wall of the sealing end of the aeration pipe, wherein the diameter of the branch pipe is matched with the inner diameter of the aeration pipe.

[0010] Preferably, a mounting block is provided on one side of the top of the gas delivery pipe, wherein the mounting block is connected to the vertical rod through a telescopic rod.

[0011] Preferably, a mounting hole for the connecting rod to pass through is provided on one of the sealed ends of the gas delivery pipe, wherein a sealing and waterproof layer is provided between the side wall of the mounting hole and the outer wall of the connecting rod.

DETAILED DESCRIPTION

[0019] The technical solution of the present invention is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0020] A sewage treatment aeration pipe structure includes an air delivery pipe 1 connected to an air delivery pump through a pipeline, wherein one side of the air delivery pipe 1 is provided with a plurality of aeration pipes 2 vertically connected thereto, and a plurality of air outlet holes 13 are evenly arranged on the side wall of the aeration pipe 2:

[0021] A branch pipe 4 having one end extending into the air pipe 1 is arranged in the aeration pipe 2, wherein the other end of the branch pipe 4 is sealed, and a rotating shaft 5 fixed to the inner wall of the aeration pipe 2 through a bearing 6 is arranged on the sealed end of the branch pipe 4, and a plurality of air outlet holes II7 staggered with the air outlet holes I3 are arranged on the side wall of the branch pipe 4, wherein a gear ring 8 is arranged at the end of the branch pipe 4 located in the air pipe 1, and a rack 9 meshing with multiple groups of gear rings 8 is arranged at the bottom of the air pipe 1, and a base 10 for fixing the rack 9 is also arranged at the bottom of the air pipe 1, wherein a connecting rod 11 extending to the outside of the air pipe 1 is arranged at one end of the rack 9, and a vertical rod 12 is arranged at the top of the connecting rod 11, and the vertical rod 12 is driven by an electric push rod 13.

[0022] In this embodiment, a through hole for the rack 9 to pass through is provided on the base 10, wherein the rack 9 drives the branch pipe 4 to rotate through the gear ring 8 so that the air outlet hole II7 on the side wall thereof can be connected with the corresponding air outlet hole I3.

[0023] like Figure 3 , 4 As shown, a boss 14 for fixing the bearing 6 is provided on the inner wall of the sealing end of the aeration pipe 2 , wherein the diameter of the branch pipe 4 is matched to the inner diameter of the aeration pipe 2 .

[0024] like Figure 1 , 2 As shown, a mounting block 15 is provided on one side of the top of the gas delivery pipe 1 , wherein the mounting block 15 is connected to the vertical rod 12 via a telescopic rod 16 .

[0025] In this embodiment, a mounting hole for the connecting rod 11 to pass through is provided on one of the sealed ends of the gas delivery pipe 1 , wherein a sealing and waterproof layer is provided between the side wall of the mounting hole and the outer wall of the connecting rod 11 .

[0026] When in use, the electric push rod 13 drives the rack 9 to slide in the air pipe 1 through the vertical rod 12 and the connecting rod 11, and then drives the gear ring 8 to rotate. The gear ring 8 drives the branch pipe 4 to rotate in the aeration pipe 2, and the rotating shaft 5 on the branch pipe 4 rotates in the bearing 6. At this time, when the branch pipe 4 rotates, it will drive the air outlet II7 on its side wall to align with the air outlet I3. Then, at this time, the gas introduced into the air pipe 1 by the air pump and the pipeline can be discharged through the branch pipe 4, the air outlet II7 and the air outlet II3. In the above process, the rotation angle of the rotating branch pipe 4 can be adjusted to adjust the size of the connecting opening between the air outlet II7 and the air outlet I3 to adjust the air outlet volume. When the work is completed, the working rack 9 drives the gear ring 8 and the branch pipe 4 to rotate, so that the air outlet II7 and the air outlet I3 are staggered.

[0027] The present invention simultaneously drives multiple groups of branch pipes 4 to rotate in the aeration pipe 2 by mechanical drive, so that the outlet holes II7 are aligned with the outlet holes I3 to facilitate the circulation of gas. Compared with the method driven by atmospheric pressure, it has stronger stability and is conducive to the circulation of gases of different strengths.

[0028] The present invention is described in detail above, but the contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of application of the present invention should still fall within the scope of the patent coverage of the present invention.
