Description

Technical Field

[0001] This utility model relates to the field of air buffer tanks, specifically an air buffer tank for photocatalytic membrane separation degradation reaction. Background Technology

[0002] Photocatalytic membrane separation degradation reaction is an environmental treatment technology that combines photocatalysis and membrane separation technologies. In the process of treating wastewater, photocatalytic membrane separation technology requires the use of a compressor, and the air buffer tank is used to stabilize the compressed air pressure output by the compressor and reduce pressure fluctuations.

[0003] According to Chinese Patent No. CN220891853U, a compressed air buffer tank is disclosed. This compressed air buffer tank utilizes the movement of a moving ring to drive an adjusting rod to rotate a pressure plate, simultaneously pressing a locking rod and a rubber air bladder. The locking rod is inserted into a through hole at the end of the insert rod, while the rubber air bladder fills the sealing air bladder with airflow. A nut is used to limit the movement of the moving ring, quickly achieving the assembly of compressed air buffer tank pipes and strengthening the seal. Its operation is simple and convenient, and it has strong leak-proof performance.

[0004] Regarding the aforementioned patent content, by setting a mesh plate inside the buffer tank to filter impurities in the gas, impurities will accumulate on the inner wall of the mesh plate after a long period of filtration. These impurities are difficult to slide down and fall to the bottom of the buffer tank through the through holes, causing impurities to accumulate on the mesh plate. Over time, this will affect the filtration effect of the mesh plate on the gas and reduce the cleaning efficiency of impurities attached to the inner wall of the mesh plate. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide an air buffer tank for photocatalytic membrane separation and degradation reaction, so as to solve the technical problem of inconvenience in cleaning impurities attached to the inner wall of the mesh plate.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an air buffer tank for photocatalytic membrane separation degradation reaction, comprising a buffer tank body, wherein a mesh plate and a cleaning assembly are respectively provided inside the buffer tank body, the cleaning assembly comprising two mounting rods installed on the upper part of the buffer tank body, a bearing seat installed between the two mounting rods, a rotating shaft connected to the bearing seat through a bearing, a fan blade installed at the top of the rotating shaft, and two connecting rods connected to the bottom of the rotating shaft, a rotating ring installed between the two connecting rods, and a rotating plate provided on one side of the bottom of the rotating ring, a scraper connected to the bottom of the rotating plate.

[0007] By adopting the above technical solution, when the rotating shaft rotates, it will drive the connecting rod to rotate, which in turn drives the rotating ring to rotate. The rotating ring then drives the rotating plate to rotate, and the rotating plate in turn drives the scraper to rotate, so that the scraper can scrape the impurities attached to the inner wall of the mesh plate, causing the impurities to fall downwards.

[0008] Furthermore, the cleaning assembly also includes threaded rods threaded to the upper sides of the buffer tank. One end of the threaded rod is connected to a retaining ring via a bearing. A slide is mounted on one side of the retaining ring via a fixing rod. A turntable is mounted on the other end of the threaded rod.

[0009] By adopting the above technical solution, when it is necessary to limit the rotation of the shaft to prevent it from rotating arbitrarily, the threaded rod can be rotated. When the threaded rod rotates, it will move and drive the retaining ring to move, so that the retaining ring locks the shaft, thereby limiting the rotation of the shaft.

[0010] Furthermore, the slide block is fitted onto the outer wall of the mounting rod, and the retaining ring is slidably connected to the mounting rod via the slide block.

[0011] By adopting the above technical solution, the circlip can drive the slide block to slide on the mounting rod when it moves, thereby improving the stability of the circlip when it moves.

[0012] Furthermore, the cleaning assembly also includes sealing rings installed on both sides inside the buffer tank, with the outer wall of the threaded rod fitting against the inner wall of the sealing ring.

[0013] By adopting the above technical solution, the sealing ring can improve the sealing performance between the threaded rod and the buffer tank, preventing gas leakage.

[0014] Furthermore, the bottom of the mesh plate is provided with a partition mesh, and a through hole is opened in the middle of the mesh plate.

[0015] By adopting the above technical solution, the through hole design allows impurities to fall downwards to the bottom of the buffer tank, facilitating their subsequent discharge.

[0016] Furthermore, the bottom of the buffer tank is provided with a discharge valve, one side of the buffer tank is provided with an air outlet, and the top of the buffer tank is provided with an air inlet.

[0017] By adopting the above technical solution, gas can enter the buffer tank through the inlet, and the gas inside the buffer tank can be discharged through the outlet.

[0018] Furthermore, a pressure gauge is installed on one side of the top of the buffer tank.

[0019] By adopting the above technical solution, the pressure gauge can be set to monitor the air pressure inside the buffer tank.

[0020] Furthermore, the bottom of the scraper is in contact with the inner wall of the mesh plate.

[0021] By adopting the above technical solution, when the scraper rotates, it will scrape off the impurities attached to the inner wall of the mesh plate, thus preventing the impurities from accumulating on the inner wall of the mesh plate and making it difficult for them to fall down and be discharged.

[0022] Furthermore, the inner wall of the retaining ring is provided with a friction pad, and the inner wall of the retaining ring is in contact with the outer wall of the rotating shaft.

[0023] By adopting the above technical solution, when the inner wall of the retaining ring is in contact with the rotating shaft, the rotating shaft can be locked and limited, thereby preventing the rotating shaft from rotating at will.

[0024] Furthermore, the fan blades are located directly below the air inlet.

[0025] By adopting the above technical solution, after the gas enters the buffer tank through the air inlet, the fan blades will be impacted by the gas and rotate, thus driving the shaft to rotate.

[0026] In summary, the present invention has the following main advantages:

[0027] 1. This utility model is equipped with a cleaning component. When gas enters the buffer tank through the air inlet, the fan blades are impacted by the gas and rotate, which in turn drives the rotating shaft to rotate. When the rotating shaft rotates, it drives the connecting rod to rotate, which in turn drives the rotating ring to rotate. The rotating ring drives the rotating plate to rotate, and the rotating plate drives the scraper to rotate. The scraper can scrape the impurities attached to the inner wall of the screen, causing the impurities to fall downwards and fall through the through hole to the lower part of the buffer tank, making it easy to discharge through the discharge valve later. This method can quickly clean the impurities accumulated on the inner wall of the screen, avoiding the impurities from accumulating on the inner wall of the screen and being difficult to clean, thereby improving the cleaning efficiency of the impurities on the inner wall of the screen.

[0028] 2. This utility model, by setting a threaded rod, a retaining ring, and a sliding block, allows the rotating shaft to be locked and limited when it is not necessary to scrape off the impurities accumulated on the inner wall of the screen. At this time, the user can rotate the threaded rod, causing it to move and drive the retaining ring to move. When the retaining ring is in contact with the outer wall of the rotating shaft, the rotating shaft can be limited. At this time, the fan blade will not rotate due to the impact of the airflow, and thus will not drive the scraper to rotate, thereby avoiding the scraper from rotating continuously. In this way, the limitation on the rotating shaft can be released only when it is necessary to clean the impurities attached to the inner wall of the screen, and the operation process is simple and convenient.

[0029] 3. This utility model incorporates a sealing ring, which improves the sealing between the threaded rod and the buffer tank, preventing gas leakage. Attached Figure Description

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0037] The embodiments of this utility model will be described below based on its overall structure.

[0038] Example 1:

[0039] An air buffer tank for photocatalytic membrane separation degradation reaction, such as Figures 1-5 As shown, the device includes a buffer tank 1. Inside the buffer tank 1, there are mesh plates 6 and cleaning components 8. The bottom of the mesh plate 6 is equipped with a partition mesh 7. A through hole 9 is opened in the middle of the mesh plate 6. The through hole 9 is designed to allow impurities to fall downwards to the bottom of the buffer tank 1, facilitating the subsequent discharge of impurities. The bottom of the buffer tank 1 is equipped with a discharge valve 5. One side of the buffer tank 1 is equipped with an air outlet 2. The top of the buffer tank 1 is equipped with an air inlet 3. Gas can enter the interior of the buffer tank 1 through the air inlet 3, and the gas inside the buffer tank 1 can be discharged through the air outlet 2. A pressure gauge 4 is installed on one side of the top of the buffer tank 1. The pressure gauge 4 is designed to monitor the air pressure inside the buffer tank 1.

[0040] See Figures 2-5The cleaning component 8 includes two mounting rods 801 installed inside and above the buffer tank 1. A bearing seat 803 is installed between the two mounting rods 801. A rotating shaft 808 is connected to the bearing seat 803 via a bearing. A fan blade 802 is installed at the top of the rotating shaft 808, and two connecting rods 813 are connected to the bottom of the rotating shaft 808. A rotating ring 806 is installed between the two connecting rods 813, and a rotating plate 804 is provided on one side of the bottom of the rotating ring 806. A scraper 807 is connected to the bottom of the rotating plate 804. When the rotating shaft 808 rotates, it will drive the connecting rods 813 to rotate, which in turn drives the rotating ring 806 to rotate. 806 drives the rotating plate 804 to rotate, and the rotating plate 804 in turn drives the scraper 807 to rotate, so that the scraper 807 can scrape the impurities attached to the inner wall of the mesh plate 6, causing the impurities to fall downwards. The bottom of the scraper 807 is in contact with the inner wall of the mesh plate 6. When the scraper 807 rotates, it will scrape off the impurities attached to the inner wall of the mesh plate 6, preventing the impurities from accumulating on the inner wall of the mesh plate 6 and making it difficult for them to fall downwards and be discharged. The fan blade 802 is located directly below the air inlet 3, so that after the gas enters the buffer tank 1 through the air inlet 3, the fan blade 802 will be impacted by the gas and rotate, driving the rotating shaft 808 to rotate.

[0041] Example 2:

[0042] Based on the above embodiment 1, in order to prevent the rotating shaft 808 and scraper 807 from rotating continuously, when there is no need to clean the impurities accumulated on the inner wall of the screen plate 6, it is necessary to limit the rotating shaft 808. Therefore, the following structure will be set.

[0043] Specifically, the cleaning component 8 also includes threaded rods 811 threadedly connected to the upper sides of the buffer tank 1. One end of the threaded rod 811 is connected to a retaining ring 810 via a bearing. A slide block 809 is mounted on one side of the retaining ring 810 via a fixing rod. A turntable is mounted on the other end of the threaded rod 811. When it is necessary to limit the rotation of the rotating shaft 808 to prevent it from rotating arbitrarily, the threaded rod 811 can be rotated. When the threaded rod 811 rotates, it will move and drive the retaining ring 810 to move, so that the retaining ring 810 locks the rotating shaft 808, thereby limiting the rotation of the shaft. 808 is used for limiting the position. The slide 809 is sleeved on the outer wall of the mounting rod 801. The retaining ring 810 is slidably connected to the mounting rod 801 through the slide 809. When the retaining ring 810 moves, it can drive the slide 809 to slide on the mounting rod 801, thereby improving the stability of the retaining ring 810 when it moves. The inner wall of the retaining ring 810 is provided with a friction pad. The inner wall of the retaining ring 810 is in contact with the outer wall of the rotating shaft 808. After the inner wall of the retaining ring 810 is in contact with the rotating shaft 808, it can lock and limit the rotating shaft 808, thereby preventing the rotating shaft 808 from rotating at will.

[0044] Example 3:

[0045] Based on the above embodiment 1, in order to improve the sealing performance between the threaded rod 811 and the buffer tank 1, the following structure will be set.

[0046] See Figures 2-5 The cleaning component 8 also includes sealing rings 805 installed on both sides inside the buffer tank 1. The outer wall of the threaded rod 811 fits against the inner wall of the sealing ring 805. The sealing ring 805 can improve the sealing between the threaded rod 811 and the buffer tank 1 and prevent gas leakage.

[0047] The working principle of this utility model is as follows: First, gas can enter the interior of the buffer tank 1 through the air inlet 3. The mesh plate 6 can filter the gas to prevent impurities from being discharged through the air outlet 2. After filtration, the gas can be discharged through the air outlet 2, and the impurities will fall into the lower interior of the buffer tank 1 through the through hole 9. The pressure gauge 4 can monitor the air pressure inside the buffer tank 1.

[0048] When it is necessary to clean the impurities accumulated on the inner wall of the mesh plate 6, the user can rotate the threaded rods 811 on both sides of the buffer tank 1, so that the threaded rods 811 move and drive the retaining rings 810 to move. After the retaining rings 810 are no longer in contact with the outer wall of the rotating shaft 808, the threaded rods 811 will no longer be rotated. At this time, after the gas enters the interior of the buffer tank 1 through the air inlet 3, the fan blades 802 will be impacted by the gas and rotate, which will drive the rotating shaft 808 to rotate. When the rotating shaft 808 rotates, it will drive the connecting rod 813 to rotate, and then drive the rotating ring 806 to rotate. The rotating ring 806 will drive the rotating plate 804 to rotate, and the rotating plate 804 will drive the scraper 807 to rotate, so that the scraper 807 can scrape the impurities attached to the inner wall of the mesh plate 6, so that the impurities fall downward and fall through the through hole 9 to the lower interior of the buffer tank 1, which will facilitate subsequent discharge through the discharge valve 5.

[0049] When it is not necessary to scrape off the impurities accumulated on the inner wall of the mesh plate 6, the rotating shaft 808 needs to be locked and limited. At this time, the user can rotate the threaded rod 811 in the opposite direction, so that the threaded rod 811 moves and drives the retaining ring 810 to reset and move. When the retaining ring 810 is in contact with the outer wall of the rotating shaft 808, the rotating shaft 808 can be limited. At this time, the fan blade 802 will not rotate due to the impact of the airflow, and thus will not drive the scraper 807 to rotate, thereby preventing the scraper 807 from rotating continuously. The setting of the sealing ring 805 can improve the sealing between the threaded rod 811 and the buffer tank 1 and prevent gas leakage.
