Description

Technical Field

[0001] This utility model relates to the field of aeration device technology, and in particular to an adjustable aeration device. Background Technology

[0002] Aeration devices are key equipment used to supply oxygen to aeration tanks in wastewater treatment processes. Their main function is to transfer oxygen from the air into the liquid within the aeration tank through appropriate methods, meeting the oxygen requirements for aerobic biological metabolism and promoting sufficient contact between organic matter, microorganisms, and dissolved oxygen, thereby accelerating the oxidative decomposition of organic matter in the wastewater. Liftable aerators are a type of aeration device that disperses air into bubbles through a microporous structure, increasing dissolved oxygen in the water and providing a living environment for microorganisms, thus decomposing organic pollutants in the wastewater.

[0003] Currently, liftable aerators generally use flange connections for installation. Specifically, the long pipe of the aerator is fixed to the branch pipe on the top of the tank using a flange. While this connection structure has the advantages of stable connection and good sealing, it also has a significant drawback—the installation height cannot be adjusted.

[0004] In actual operation, the bottom of the aeration tank may require changes in the immersion depth of the aerators due to errors during construction, foundation settlement, or process adjustments. In such cases, adjusting the aerator height necessitates replacing long pipes or cutting existing pipes, which undoubtedly makes the operation process extremely cumbersome.

[0005] Furthermore, to improve oxygen utilization when dealing with different water quality conditions or treatment loads, the height of the aerator often needs to be optimized and adjusted. However, this fixed structural design makes the aerator unable to flexibly respond to these adjustment requirements.

[0006] Therefore, we propose an adjustable aeration device. Utility Model Content

[0007] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adjustable aeration device.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable aeration device, including an air distribution pipe, wherein tubular aerators are fixedly connected to both sides of the outer surface of the air distribution pipe, and a long pipe is fixedly connected to the top of the air distribution pipe, and a thick pipe is sealed and sleeved on the outer surface of the long pipe.

[0009] A connecting plate is fixedly sleeved on the outer surface of the long tube. A sliding rod is fixedly connected to one side of the outer surface of the connecting plate. A spring pin is fixedly embedded on one side of the outer surface of the sliding rod. A through hole extending to the other side is opened on the top of one side of the outer surface of the sliding rod. A pulling component is installed between the through hole and the spring pin.

[0010] A positioning groove assembly is fixedly connected to one side of the outer surface of the thick tube, and a sliding sleeve is fixedly connected to one side of the outer surface of the positioning groove assembly, with the sliding sleeve slidably sleeved on the outer surface of the slide rod.

[0011] Furthermore, a piston ring is fixedly fitted onto the outer surface of the long tube, and the outer wall of the piston ring is sealed and fitted to the inner wall of the thick tube. The setting of the piston ring ensures the sealing between the long tube and the thick tube, so that the gas will not leak during the adjustment process and the aeration effect is stable.

[0012] Furthermore, a mounting flange is fixedly connected to the top of the thick pipe, which facilitates quick connection with external pipelines and improves the overall installation efficiency of the equipment.

[0013] Furthermore, the spring pin includes a housing, which is fixedly embedded in one side of the slide rod. A spring body is fixedly connected to the inner wall of one side of the housing, and a limiting plate is fixedly connected to the other end of the spring body. An insert plate is fixedly connected to one side of the limiting plate, and the insert plate passes through the housing and is slidably connected to the housing. Through the cooperation of the housing, the spring body, the limiting plate, and the insert plate, the spring pin can automatically reset and lock its position after adjustment, ensuring that the aerator will not be accidentally displaced during use.

[0014] Furthermore, the pulling assembly includes a pull rod, which is disposed inside the through hole. A movable rod is fixedly connected to the bottom of the pull rod, and the movable rod extends through the bottom wall of the through hole to the interior of the slide rod and is slidably connected to the slide rod. A pull rope is fixedly connected to the bottom of the movable rod, and the pull rope extends through the housing and is fixedly connected to the limiting plate. The pulling assembly, through the linkage design of the pull rod, the movable rod, and the pull rope, makes the unlocking operation more effortless and convenient.

[0015] Furthermore, each of the positioning slot groups includes a long seat, and the long seat is fixedly connected to the thick tube and the sliding sleeve. Multiple positioning slots are evenly opened on one side of the outer surface of the long seat, and the positioning slots are matched with the insert plate. Multiple positioning slots and insert plates can cooperate to achieve multiple fixation positions.

[0016] The beneficial effects of this utility model are:

[0017] 1. In use, this utility model utilizes the cooperation of a sliding rod, spring pin, and positioning groove assembly to allow the long pipe to slide along the thicker pipe and lock in different positions, thereby flexibly adjusting the immersion depth of the air distribution pipe and the tubular aerator. Compared to the traditional fixed flange connection method, this structure achieves height adjustment without cutting the pipe or replacing the long pipe, effectively solving the problem of aerator height adaptation caused by construction errors, foundation settlement, or process changes, and significantly improving the convenience of installation and maintenance.

[0018] 2. When in use, this utility model uses the sliding sealing cooperation between the long pipe and the thick pipe to maintain the air passage's sealing while adjusting the aeration depth, ensuring stable gas delivery to the air distribution pipe and tubular aerator.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1-4 As shown, an adjustable aeration device is disclosed, comprising an air distribution pipe 1, with tubular aerators 2 fixedly connected to both sides of the outer surface of the air distribution pipe 1, and a long pipe 3 fixedly connected to the top of the air distribution pipe 1. A thick pipe 4 is sealed and sleeved on the outer surface of the long pipe 3, and a piston ring 14 is fixedly sleeved on the outer surface of the long pipe 3. The outer wall of the piston ring 14 is sealed and fitted to the inner wall of the thick pipe 4. The piston ring 14 is made of wear-resistant fluororubber material, and the ring body is provided with two sealing lips, which can still maintain good sealing performance under air pressure of 0.3-0.5MPa.

[0028] The top of the thick pipe 4 is fixedly connected to a mounting flange 5.

[0029] A connecting plate 9 is fixedly sleeved on the outer surface of the long tube 3. A slide rod 7 is fixedly connected to one side of the outer surface of the connecting plate 9. A spring pin is fixedly embedded on one side of the outer surface of the slide rod 7. The spring pin includes a housing 18, and the housing 18 is fixedly embedded on one side of the slide rod 7. A spring body 17 is fixedly connected to the inner wall of one side of the housing 18. A limiting plate 16 is fixedly connected to the other end of the spring body 17. An insert plate 15 is fixedly connected to one side of the limiting plate 16. The insert plate 15 passes through the housing 18 and is slidably connected to the housing 18. The insert plate 15 is made of stainless steel wire cutting and has a 15-degree guide slope at the head. The spring body 17 is made of piano wire and is stress-relieved annealed. Its elastic coefficient is 3N / mm. The surface is coated with Teflon to reduce the coefficient of friction with the positioning slot 13.

[0030] A through hole 10 is provided on the top of one side of the outer surface of the slide rod 7, extending to the other side. A pulling assembly is installed between the through hole 10 and the spring pin. The pulling assembly includes a pull rod 11, which is located inside the through hole 10. A movable rod 12 is fixedly connected to the bottom of the pull rod 11. The movable rod 12 extends through the bottom wall of the through hole 10 into the interior of the slide rod 7 and is slidably connected to the slide rod 7. A pull rope 19 is fixedly connected to the bottom of the movable rod 12. The pull rope 19 passes through the housing 18 and is fixedly connected to the limiting plate 16. The pull rod 11 is made of nylon injection molding with anti-slip texture on the surface. The movable rod 12 is made of 304 stainless steel rod with a hardened surface. The pull rope 19 is a 7×7 stainless steel wire rope structure.

[0031] A positioning groove assembly is fixedly connected to one side of the outer surface of the thick pipe 4. A sliding sleeve 6 is fixedly connected to one side of the outer surface of the positioning groove assembly. The sliding sleeve 6 is slidably sleeved on the outer surface of the slide rod 7. Each positioning groove assembly includes a long seat 8, which is extruded from aluminum alloy. The long seat 8 is fixedly connected to the thick pipe 4 and the sliding sleeve 6. Multiple positioning slots 13 are evenly opened on one side of the outer surface of the long seat 8. The positioning slots 13 match the insert plate 15. The sliding sleeve 6 is made of oil-impregnated bronze bushing. An oil storage groove is opened in the inner hole. Rubber sealing rings are set at both ends of the sleeve to prevent sewage from seeping in.

[0032] Working principle: The operator holds the slide bar 7 with one hand and pulls the lever 11 with the middle and index fingers at the same time. The lever 11 drives the movable rod 12 to move upward. The pull rope 19 at the bottom of the movable rod 12 is pulled, which pulls the limiting plate 16 in the spring pin to compress the spring body 17, so that the insert plate 15 is removed from the current positioning slot 13 and the locking state is released.

[0033] Since the slide bar 7 is fixed to the connecting plate 9, and the connecting plate 9 is fixed to the long tube 3, the long tube 3 will move upwards simultaneously when the slide bar 7 is lifted.

[0034] The thick pipe 4 is fixed to the external aeration branch pipe by the mounting flange 5 at the top, so the thick pipe 4 remains stationary, while the long pipe 3 drives the piston ring 14 to slide inside the thick pipe 4.

[0035] The movement of the long tube 3 changes the depth to which it extends into the thick tube 4, thereby adjusting the path length of the gas entering the gas distribution pipe 1 and the immersion depth of the gas distribution pipe 1.

[0036] Since the tubular aerator 2 is fixed on the air distribution pipe 1, the entire air distribution pipe 1 and the tubular aerator 2 will change the immersion depth as the long pipe 3 is raised and lowered.

[0037] Once the long tube has moved to the target position, the operator releases the lever 11, the spring body 17 rebounds, and pushes the insert plate 15 to re-engage into the positioning slot 13, so that the slide rod 7 and the sliding sleeve 6 on the thick tube 4 are fixed again, completing the adjustment.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
