Description

Technical Field

[0001] This utility model relates to the technical field of sewage tank aeration devices, specifically a sewage biochemical jet long tube microporous aeration device. Background Technology

[0002] Wastewater treatment refers to the process of purifying wastewater to meet the water quality requirements for discharge into a water body or reuse. Aeration is required in wastewater treatment, so an aeration device is needed.

[0003] Existing aeration devices typically use blowers in conjunction with aeration discs installed at the bottom of the tank to aerate the interior of the wastewater treatment tank. However, these common aeration devices still have shortcomings:

[0004] Traditional aeration devices suffer from uneven aeration and numerous dead zones, leading to severe sludge accumulation, low tank volume utilization, and low oxygen utilization. This results in higher blower consumption and costs. Furthermore, the large amount of sludge required for tank cleaning increases the cost of cleaning and generates a large amount of hydrogen sulfide during the cleaning process, posing a safety hazard. Utility Model Content

[0005] The purpose of this invention is to provide a wastewater biochemical jet long-tube microporous aeration device to solve the problems mentioned in the background art, such as uneven aeration, many dead zones, serious sludge accumulation, low tank volume utilization, low oxygen utilization, higher blower consumption, higher cost, and high cost of tank cleaning when more sludge is required, and the generation of a large amount of hydrogen sulfide during the cleaning process, which may pose a safety hazard.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sewage biochemical jet long tube microporous aeration device, comprising a sewage tank and a support plate fixedly connected to one end of the sewage tank. An aeration system is fixedly installed on the top of the support plate. An air inlet component is fixedly connected to one end of the aeration system. The air inlet component is fixedly installed on one end of the inner wall of the sewage tank. A connecting component is fixedly installed on the other end of the inner wall of the sewage tank. Multiple aeration hoses are provided between the connecting component and the air inlet component. Multiple bracket components for supporting and restricting the aeration hoses are fixedly installed on the bottom of the inner wall of the sewage tank.

[0007] Preferably, the aeration system includes a jet circulation pump, which is fixedly mounted on a support plate. A reinforcing plate is fixedly connected to the connection between the support plate and the sewage tank. The jet circulation pump has an inlet and an outlet at both ends, respectively. A water suction pipe is fixedly connected to one end of the inlet, and an air supply pipe is fixedly connected to one end of the outlet.

[0008] Preferably, one end of the water suction pipe is fixedly installed with an anti-clogging component for filtering impurities. The anti-clogging component includes an anti-clogging sleeve, which is fixedly installed on the water suction pipe. The anti-clogging sleeve has mounting grooves on both sides of its inner wall. Limiting screws are threaded to both sides of the anti-clogging sleeve extending into the mounting grooves. Self-cleaning filter plates are provided inside the two mounting grooves.

[0009] Preferably, the self-cleaning filter plate includes a filter plate, with mounting blocks fixedly connected to both sides of the filter plate, and pressure plates fixedly connected to one side of each of the two mounting blocks. The surface of the mounting blocks is slidably connected to the interior of the mounting groove. An anti-clogging blade is rotatably connected to one side of the filter plate, and a cleaning brush is provided on one side of the anti-clogging blade.

[0012] Compared with existing technologies, the beneficial effects of this utility model are as follows: Aeration is achieved by using a flexible aeration hose, which generates microbubbles.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] Please see Figures 1-5 This utility model provides a sewage biochemical jet long tube microporous aeration device, including a sewage tank 1 and a support plate 2 fixedly connected to one end of the sewage tank 1. An aeration system is fixedly installed on the top of the support plate 2. An air inlet component is fixedly connected to one end of the aeration system. The air inlet component is fixedly installed on one end of the inner wall of the sewage tank 1. A connecting component is fixedly installed on the other end of the inner wall of the sewage tank 1. Multiple aeration hoses 7 are provided between the connecting component and the air inlet component. Multiple bracket components for supporting and limiting the aeration hoses 7 are fixedly installed at the bottom of the inner wall of the sewage tank 1.

[0021] See Figures 2-3 Furthermore, the aeration system includes a jet circulation pump 3, which is fixedly mounted on a support plate 2. A reinforcing plate 4 is fixedly connected to the connection between the support plate 2 and the sewage tank 1. The jet circulation pump 3 has an inlet and an outlet at both ends, respectively. One end of the inlet is fixedly connected to a suction pipe 19, and one end of the outlet is fixedly connected to an air supply pipe 5. ，The air intake assembly includes an air intake main pipe 6, which is connected to the air supply pipe 5. The connecting assembly includes a connecting rod 10. Multiple anti-bend heads 8 are provided on the surfaces of the connecting rod 10 and the air intake main pipe 6. Multiple fixing rings 9 are provided on the surfaces of the connecting rod 10 and the air intake main pipe 6. The multiple fixing rings 9 are fixedly installed in the sewage tank 1.

[0022] When in use, when the jet circulation pump 3 is started, the suction pipe 19 draws water from the sewage tank 1 through the inlet, forming an oxygen-rich gas-liquid mixture inside the jet circulation pump 3. This mixture is then transported to the air inlet main pipe 6 through the air outlet connected to the air delivery pipe 5. Multiple aeration hoses 7 are connected to the surface of the air inlet main pipe 6. Anti-bend heads 8 are installed at the connection points between the aeration hoses 7 and the air inlet main pipe 6 to guide the aeration hoses 7 and prevent bending that would affect the performance. Gas enters the interior of the multiple aeration hoses 7 through the air inlet main pipe 6. The aeration hoses 7 are made of TPU material. The air intake pipe 6 is fixed by a fixing ring 9, which is itself fixed to the wall of the sewage tank 1 by bolts. A connecting rod 10 is set at the other end of the sewage tank 1. The connecting rod 10 is also limited by the fixing ring 9. One end of the aeration hose 7 is connected to the connecting rod 10 and the port is also sealed by the connecting rod 10. Similarly, an anti-bend head 8 is set to prevent bending. Several support components are set at the bottom of the sewage tank 1 to support the aeration hose 7 to a certain distance from the bottom of the tank. In this way, aeration inside the sewage tank 1 can be achieved by a jet circulation pump 3.

[0023] See Figure 4 Furthermore, the support assembly includes a semi-ring support rod 11, with two shaft plates 12 fixedly connected to one side of the top end of the semi-ring support rod 11. A limiting semi-ring 15 is matched with the semi-ring support rod 11. A connecting rotating rod 14 is fixedly connected to one side of the limiting semi-ring 15. The connecting rotating rod 14 is rotatably connected between the two shaft plates 12. A connecting hanging plate 13 is rotatably connected to one end of the semi-ring support rod 11. Several return springs 18 are fixedly connected to the other side of the limiting semi-ring 15. A connecting hanging rod 16 is fixedly connected to the surface of the limiting semi-ring 15. A limiting piece 17 is fixedly connected to one end of the connecting hanging rod 16. The connecting hanging plate 13 is engaged with the connecting hanging rod 16.

[0024] During use, the aeration hose 7 is a certain distance from the bottom of the pool, so it needs to be supported by a support assembly. After installing the support assembly on the bottom of the pool, when arranging the aeration hose 7, press down on the limiting half-ring 15. The limiting half-ring 15 is equipped with a connecting rotating rod 14, which is rotatably connected between the two shaft plates 12 on the half-ring support rod 11. Therefore, the limiting half-ring 15 can rotate relative to the half-ring support rod 11. At this time, the return spring 18 is compressed, and the connecting hanging rod 16 connected to the limiting half-ring 15 moves downward with the limiting half-ring 15, moving to the slot outlet of the connecting hanging plate 13. Rotate the connecting plate 13 to rotate the limiting half-ring 15 to the other side, allowing the aeration hose 7 to be placed directly on it. Then, reset the limiting half-ring 15 and press it downwards. Rotate the connecting plate 13 to engage with the connecting rod 16. At this time, the elasticity of the return spring 18 can maintain the engagement between the two. When the aeration hose 7 aerates, it also applies an upward force to the limiting half-ring 15 without damaging the engagement between the connecting plate 13 and the connecting rod 16. This makes it easier to lay and install the aeration hose 7 and perform subsequent maintenance.

[0025] See Figure 5 Furthermore, an anti-clogging component for filtering impurities is fixedly installed at one end of the suction pipe 19. The anti-clogging component includes an anti-clogging sleeve 20, which is fixedly installed on the suction pipe 19. Installation grooves 21 are provided on both sides of the inner wall of the anti-clogging sleeve 20. Limiting screws 27 are threadedly connected to both sides of the anti-clogging sleeve 20 extending into the installation grooves 21. Self-cleaning filter plates are installed inside the two installation grooves 21. ， The self-cleaning filter plate includes a filter plate 22, with mounting blocks 23 fixedly connected to both sides of the filter plate 22. A pressure plate 24 is fixedly connected to one side of each mounting block 23. The surface of the mounting block 23 is slidably connected to the inside of the mounting groove 21. An anti-clogging blade 25 is rotatably connected to one side of the filter plate 22. A cleaning brush 26 is provided on one side of the anti-clogging blade 25. The surface of the limiting screw 27 abuts against the surface of the pressure plate 24.

[0026] During operation, the jet circulation pump 3 needs to continuously pump water from the sewage tank 1. However, the sewage tank 1 contains many impurities. If the water pumped into the jet circulation pump 3 is not filtered, it is highly likely to damage the pump and reduce its service life. Therefore, an anti-clogging sleeve 20 is added to the inlet end of the suction pipe 19. Installation grooves 21 are provided on both sides of the inner wall of the anti-clogging sleeve 20. Installation blocks 23 are provided on both sides of the filter plate 22. The installation blocks 23 are placed into the installation grooves 21. A limit screw 27 is threadedly connected to the anti-clogging sleeve 20 at the position corresponding to the installation groove 21. At this time, rotating the limit screw 27 moves it towards the installation groove 21. A micro-angle pressure is provided above the installation block 23. When the limiting screw 27 moves horizontally, it increases the pressure on the filter plate 22, making the filter plate 22 more securely installed. An anti-clogging blade 25 is rotatably connected to the middle of the filter plate 22, and a cleaning brush 26 on the anti-clogging blade 25 contacts the surface of the filter plate 22. When the jet circulation pump 3 draws water through the suction pipe 19, the water flow passing through the anti-clogging blade 25 causes it to rotate the cleaning brush 26, cleaning the surface of the filter plate 22. This effectively reduces clogging during use, and the filter plate 22 can be removed periodically for thorough cleaning. The limiting screw 27 ensures convenient installation, subsequent maintenance, cleaning, and disassembly, saving time and effort.

[0027] In this embodiment, the anti-clogging paddle 25 is a waterwheel design with a brush added to one side. As water flows over it, the paddle rotates, cleaning the filter plate 22 using the potential energy of the water flow. This effectively protects the equipment and extends its lifespan. The limiting plate 17 prevents the locking structure between the connecting plate 13 and the connecting rod 16 from disengaging. Aeration is achieved using an aeration hose 7, which generates microbubbles. These microbubbles rise slowly, effectively removing impurities from the water and have high oxygen utilization, reducing energy consumption of blowers and other related equipment, thus saving costs. The long aeration hose 7 can almost completely cover the bottom of the pool, significantly reducing aeration dead zones. This method also... This invention effectively reduces sludge accumulation in the pool, lowers costs and hydrogen sulfide generation during pool cleaning, and reduces safety hazards.
