Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to an aeration device for an MBR membrane bioreactor. Background Technique

[0002] An aeration device refers to the equipment that supplies oxygen to an aeration tank during the wastewater activated sludge process of water treatment. Aeration means artificially introducing air into a biochemical aeration tank through appropriate equipment to achieve the expected purpose. Aeration not only makes the liquid in the tank contact with air for oxygenation, but also accelerates the transfer of oxygen in the air to the liquid due to the agitation of the liquid, thus completing the purpose of oxygenation. In addition, aeration also has the purpose of preventing the suspension in the tank from sinking and strengthening the contact between the organic matter, microorganisms and dissolved oxygen in the tank, so as to ensure that the microorganisms in the tank can oxidize and decompose the organic matter in the sewage under the condition of sufficient dissolved oxygen. The aeration system is widely used in the actual application of membrane bioreactor (MBR) projects. The membrane bioreactor (MBR) requires relatively sufficient oxygen during the biochemical reaction, and an aeration device is installed at the bottom of its installation location.

[0003] In the existing technical solutions, the publication number: CN112537843B, an MBR energy-saving aeration device and method, is proposed, which includes a pool body, a biochemical aeration chamber, an injection pipe, a partition net, a scraping device, a partition board, a valve, an MBR chamber, a sealing device, an aeration head, an air supply pipe, a driving fan, an electric control box, a membrane bioreactor, a water outlet pipe and a water pump, and a scraping device is installed at the upper end of the partition net.

[0004] In order to solve the problems of waste of oxygen supply by the aeration heads in the MBR chamber and low energy-saving effect, the existing technology is to install a sealing device at the right end of the bottom of the MBR chamber. When aerating the biochemical aeration chamber, most of the aeration heads in the MBR chamber are sealed by the sealing device to reduce resource waste. However, there will still be a situation where the aeration heads of the aeration device stop aerating the water, so the suspended debris in the water will fall under the influence of gravity, and the falling suspended debris is likely to block the micropores on the aeration heads, which will further affect the subsequent use of the aeration device.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] The following further describes the present utility model in detail with reference to the embodiments:

[0033] Embodiment 1

[0034] As Figures 1-5As shown in the figure, the utility model provides an aeration device for an MBR membrane bioreactor, which includes an aeration pipeline 1. One end of the aeration pipeline 1 is fixedly connected to an air inlet pipe 2. The top of the aeration pipeline 1 is fixedly connected to an air delivery pipe 3. The top of the air delivery pipe 3 is fixedly sleeved with a support plate 31. The center of the top of the support plate 31 is movably sleeved with a connecting pipe 4. The top of the connecting pipe 4 is fixedly installed with a transmission air pipe 5. The top of the transmission air pipe 5 is fixedly installed with an aeration head 6. One side of the top of the support plate 31 is fixedly sleeved with a motor 32. The driving end of the motor 32 is provided with a rotating mechanism. The rotating mechanism includes a transmission column 33. The bottom of the transmission column 33 is fixedly installed at the driving end of the motor 32. The top of the transmission column 33 is fixedly installed with a transmission gear 34. The outside of the transmission gear 34 is meshed with a rotating gear 35. The inside of the rotating gear 35 is fixedly sleeved on the outside of the connecting pipe 4. When the aeration pipeline 1 transmits air to the aeration head 6 to start aeration, the motor 32 is driven to rotate the transmission column 33. The transmission column 33 drives the transmission gear 34 to mesh and drive the rotating gear 35 to rotate, so that the rotating gear 35 drives the connecting pipe 4 to rotate on the support plate 31. Thus, the connecting pipe 4 rotates the aeration head 6 along the transmission air pipe 5, effectively rotating the aeration head 6 during aeration, improving the flexibility of the device, facilitating better aeration of the aeration head 6, and improving the aeration quality.

[0035] Embodiment 2

[0036] As Figures 1-5As shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, a support rod 61 is fixedly installed at the center of the top of the aeration head 6, and a protection mechanism is arranged at the top of the support rod 61. The protection mechanism includes a support bottom plate 62, the bottom of the support bottom plate 62 is fixedly installed at the top of the support rod 61, a shock-absorbing spring column 621 is fixedly installed at the top of the support bottom plate 62, a pressing column 622 is movably installed at the top of the shock-absorbing spring column 621, a connecting frame 623 is fixedly installed on the outer side of the pressing column 622, one end of the connecting frame 623 is fixedly installed with an extrusion column 624, an installation disc 63 is fixedly installed at the top of the extrusion column 624, a fixing frame 64 is fixedly installed on the outer side of the installation disc 63, and one end of the fixing frame 64 is fixedly installed with a conical baffle 7. When the aeration device is not in use, the suspended impurities in the water will fall under the influence of gravity. At this time, the conical baffle 7 can block the falling suspended impurities, thereby avoiding the suspended impurities in the water from falling on the aeration head 6 and also improving the service life of the aeration head 6. The impurities falling on the conical baffle 7 can slide down along the inclined surface. When the conical baffle 7 blocks impurities with a larger mass, there is a certain impact force, causing the conical baffle 7 to be pressed downward along the fixing frame 64 to press the installation disc 63. The installation disc 63 presses the extrusion column 624 downward, causing the extrusion column 624 to drive the pressing column 622 to press the shock-absorbing spring column 621 along the connecting frame 623. By using the buffering property of the shock-absorbing spring column 621, the force received by the conical baffle 7 can be buffered, thereby enhancing the protection of the conical baffle 7.

[0037] Embodiment 3

[0038] As Figures 1-5 shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, a motor 71 is fixedly sleeved at the top of the conical baffle 7, a rotating column 711 is fixed at the driving end of the motor 71, a support block 72 is fixedly installed at the top of the rotating column 711, one end of the support block 72 is fixedly installed with a support frame 73, one end of the support frame 73 is fixedly installed with a scraper 74, a chute 75 is opened on the outer side of the conical baffle 7, a slider 751 is movably installed inside the chute 75, one end of the top of the slider 751 is fixedly installed with a fixing block 752, and one side of the fixing block 752 is fixedly installed at one end of the scraper 74. When the conical baffle 7 conducts long-term blocking protection and adheres to more impurities on the top, the motor 71 drives the support block 72 to rotate along the rotating column 711, causing the support block 72 to drive the scraper 74 along the support frame 73. Thus, the scraper 74 drives the slider 751 to slide and rotate inside the chute 75 along the fixing block 752, so that the scraper 74 cleans and scrapes the impurities adhering to the top of the conical baffle 7. There is no need for manual operation for cleaning, which saves time and effort and improves the convenience of the device.

[0039] Next, the working principle of the aeration device of the MBR membrane bioreactor will be specifically described.

[0040] like Figures 1-5 As shown, when the aeration pipe 1 transmits air to the aeration head 6 to start aeration, the transmission column 33 is driven to rotate by the motor 32, and the transmission column 33 drives the transmission gear 34 to mesh with the transmission rotating gear 35 to rotate, so that the rotating gear 35 drives the connecting pipe 4 to rotate on the support plate 31, so that the connecting pipe 4 rotates the aeration head 6 along the transmission air pipe 5, and effectively rotates the aeration head 6 during aeration, thereby improving the flexibility of the device, facilitating better aeration of the aeration head 6, and improving the aeration quality. When the aeration device is not in use, suspended debris in the water will fall due to gravity. At this time, the conical baffle 7 can block the falling suspended debris, thereby preventing the suspended debris in the water from falling on the aeration head 6, and also improving the service life of the aeration head 6. The debris falling on the conical baffle 7 can slide down along the inclined surface. When the conical baffle 7 blocks the debris with larger mass, There is a certain impact force, so that the conical baffle plate 7 is forced to press the mounting plate 63 downward along the fixing frame 64, and the mounting plate 63 presses the extrusion column 624 downward, so that the extrusion column 624 drives the pressing column 622 along the connecting frame 623 to press the shock-absorbing spring column 621. The buffering property of the shock-absorbing spring column 621 can buffer the force received by the conical baffle plate 7, thereby enhancing the protective property of the conical baffle plate 7. When the conical baffle plate 7 is used for long-term isolation and protection and a lot of debris is adhered to the top, the motor 71 drives the support block 72 to rotate along the rotating column 711, so that the support block 72 drives the scraper 74 along the supporting frame 73, so that the scraper 74 drives the slider 751 to slide and rotate in the slide groove 75 along the fixing block 752, so that the scraper 74 cleans and scrapes the debris adhered to the top of the conical baffle plate 7, and no manual operation is required for cleaning, which saves time and effort and improves the convenience of the device.

[0041] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
