Description

Technical Field

[0001] The present invention relates to the technical field of aeration reactors, and in particular to a roll-type MABR aeration reactor. Background Art

[0002] The working principle of MABR is to use microporous membrane as a carrier for biofilm growth and as a medium for oxygen transfer. Organic matter in sewage is degraded by microorganisms on the biofilm, and oxygen is directly transferred to the biofilm through the microporous membrane, providing the necessary oxygen for the growth and metabolism of microorganisms. For example, the patent announcement number is CN217265065U, a flat-plate MABR membrane reactor, including a flat-plate membrane frame, a spreading MABR filter membrane unit is arranged inside the flat-plate membrane frame, an air inlet pipe and an air outlet pipe are arranged at one end of the flat-plate membrane frame, the flat-plate membrane frame is inside the reactor frame, a main air inlet pipe is arranged at the upper end of the reactor frame, a branch air supply pipe is connected to the outside of the main air inlet pipe, and the other end of the branch air supply pipe is connected to the main air outlet pipe, a connecting frame is arranged at the upper end of the reactor frame, and a supporting foot corresponding to the connecting frame is arranged at the lower end of the reactor frame. The device can be assembled quickly. There is no need to shut down the sewage device in operation. The MABR membrane reactor can be hung in the sewage pool for inspection and maintenance, thereby improving the overall installation efficiency. At the same time, the speed of sewage purification will not be delayed during the installation process. At the same time, the superposition of two membrane reactors can save floor space and improve purification efficiency.

[0003] However, during the use of the existing MABR aeration reactor, a large amount of organic matter will accumulate on the surface of the MABR membrane due to the aeration reaction. After long-term use, a large amount of organic matter will be distributed on the surface of the MABR membrane. Therefore, during subsequent aeration, the organic matter in the sewage will be blocked by the organic matter reacting between them, making it impossible for the subsequent gas to react with the organic matter in the sewage. For this reason, the present application designs a roll-type MABR aeration reactor that can perform self-cleaning during the reaction to avoid blockage of the MABR membrane surface due to long-term reaction.

[0024] 3.

[0052] The reaction component 5 is composed of two layers of MABR reaction membranes 501 and a single-layer support net 502, so as to achieve sufficient contact between sewage and the MABR reaction membrane 501. Compared with the existing MABR membrane, the present application realizes double-sided reaction, and oxygen is transported in the ventilation channel 503, so that oxygen can perform real-time aeration operation on the MABR reaction membranes 501 on both sides, making the aeration efficiency more efficient.

[0053] like Figures 1 to 20 As shown, the placement component 4 includes two placement rings 409, each of which has a roll-type bracket 401 fixedly installed inside, and the surface of the roll-type bracket 401 is provided with a fixed winding plate 407 for winding around the reaction component 5, and a connecting main rod 408 is fixedly installed in the center of the roll-type bracket 401, and the roll-type brackets 401 on both sides are respectively installed at both ends of the connecting main rod 408, and the lower roll-type bracket 401 is placed on the upper side of the support bearing 8.

[0054] It should be noted that a roll-shaped groove 402 is provided inside the roll-shaped bracket 401, and a roll-shaped slide plate 403 is movably installed inside the roll-shaped groove 402;

[0055] A plurality of limiting slide grooves 4031 are provided inside the roll-type slide plate 403, and a slide seat 404 is movably installed inside the limiting slide groove 4031 through a first spring 406. A matching clamping block 405 is installed on the upper end of the slide seat 404. The matching clamping block 405 cooperates with the fixed winding plate 407 to fix the combined film layer 504. A guide slope 4021 is provided on the side of the roll-type groove 402, and the guide slope 4021 cooperates with the matching clamping block 405 to limit the position.

[0056] Among them, an extension frame 4011 is installed on one side of the roll-type bracket 401, an adjusting screw rod 4013 is installed inside the extension frame 4011, a connecting screw sleeve 4012 is arranged inside the extension frame 4011, the connecting screw sleeve 4012 is connected to the roll-type slide plate 403, a knob 4014 is installed at one end of the adjusting screw rod 4013, and the rod body of the adjusting screw rod 4013 is threadedly matched with the connecting screw sleeve 4012.

[0057] Before use, the reaction assembly 5 needs to be wound around the fixed winding plate 407 to achieve preliminary positioning, and then the knob 4014 is turned to rotate the adjusting screw rod 4013. During the rotation of the adjusting screw rod 4013, the coiled slide plate 403 is limited by the coiled groove 402, so that when the adjusting screw rod 4013 and the connecting screw sleeve 4012 are threadedly matched, the height position of the coiled slide plate 403 is adjusted, and then the matching clamping block 405 is moved up. When the matching clamping block 405 moves up, it will contact the guide slope 4021. Under the guidance of the guide slope 4021, the adjusting screw rod 4013 and the connecting screw sleeve 4012 are threadedly matched, and the height position of the coiled slide plate 403 is adjusted. The lower sliding seat 404 will adjust its position so that the matching clamping block 405 will move closer to the fixed winding plate 407, thereby clamping and installing the combined membrane layer 504 in the reaction component 5. The above structure can support the MABR reaction membrane 501 in the present application to avoid the MABR reaction membrane 501 from falling off due to the lack of a fixed structure. In addition, the above structure can control the spacing of the MABR reaction membrane 501 to avoid the MABR reaction membrane 501 from overlapping, so that the blocking impurities can be cleaned out in the subsequent self-cleaning process.

[0058] In the present application, the connecting rod 408 is provided with an extension seat 410, a connecting rod 4102 is movably provided inside the extension seat 410, a first socket 4101 is provided outside the connecting rod 4102, and an air intake duct 4103 is provided on one side of the first socket 4101;

[0060] The first socket 4101 and the second socket 4112 are respectively installed with a first clamping plate 4104 and a second clamping plate 4113 via a second spring 412 . The first socket 4101 and the second socket 4112 are respectively connected to two ends of the reaction component 5 and the reaction component 5 is clamped by the first clamping plate 4104 and the second clamping plate 4113 .

[0061] After going around to the reaction component 5, the first socket 4101 and the second socket 4112 can be connected to the two ends of the reaction component 5, and one end of the reaction component 5 is blocked under the action of the second clamp 4113, while the first clamp 4104 temporarily fixes the other end of the reaction component 5 to ensure that the oxygen discharged from the subsequent air intake pipe 4103 can enter the ventilation channel 503 in the reaction component 5 to achieve stable air supply operation.

[0062] In the specific configuration, a buffer through hole 4086 is provided on one side of the connecting main rod 408, a circulation channel 4084 is provided through the middle of the connecting main rod 408, and a guide spiral blade 4085 for guiding water flow downward is provided on the inner wall of the circulation channel 4084.

[0063] When the connecting main rod 408 rotates, the guide spiral blade 4085 rotates accordingly to concentrate the liquid on the upper side and discharge it downward to improve the fluidity of the liquid. During self-cleaning, the roll-type bracket 401 will rotate as a whole. In order to prevent the water flow from concentrating in the middle of the roll-type bracket 401, the buffer through hole 4086 is used to transfer the concentrated water flow into the circulation channel 4084, and then the guide spiral blade 4085 performs the diversion operation.

[0064] In the specific setting, a second connecting seat 4081 is fixedly installed on the upper end of the connecting main rod 408, a steering air pipe 4082 is installed inside the second connecting seat 4081, the lower end of the steering air pipe 4082 is connected to the air intake pipe 4103, and a docking chuck 4083 is installed on the lower end of the connecting main rod 408.

[0065] A steering air pipe 4082 is arranged inside the second connecting seat 4081, wherein the upper end of the steering air pipe 4082 is located at the center of the reaction tank 1, and the lower end thereof is located at the air intake pipe 4103. The steering air pipe 4082 is used to extend the channel of the air intake pipe 4103 to the center for subsequent connection.

[0066] like Figures 1 to 11 , Fig.16 , Fig. 20As shown, the driving assembly 3 includes a fixing frame 301, which is mounted on the upper end of the sealing upper cover 2, and a hollow shaft motor 302 is mounted inside the fixing frame 301, and the output end of the hollow shaft motor 302 is connected to the rotating shaft 304, and a first connecting seat 306 is installed at the bottom of the rotating shaft 304 through a first auxiliary blade 305 for guiding the water flow inward, and the first connecting seat 306 is interlaced and docked with the second connecting seat 4081;

[0067] An air connection pipe 303 is installed at the upper end of the steering air pipe 4082 , and the air connection pipe 303 passes through the center of the hollow shaft motor 302 .

[0068] By starting the hollow shaft motor 302, the first connecting seat 306 can be driven to rotate, and the second connecting seat 4081 can be driven to rotate accordingly, so that the connecting main rod 408 can be rotated as a whole. The rotation of the connecting main rod 408 also causes the roll-type bracket 401 and the reaction component 5 installed therein to rotate. Under the action of rotation, water will pour into the inside. The roll-type design of the MABR reaction membrane 501 is utilized, so that the water will gradually flush inward, discharge impurities on the surface of the MABR reaction membrane 501, and realize self-cleaning operation.

[0069] In this embodiment, a mating shaft 601 is rotatably installed at the center of the lower water storage tank 6. The middle of the mating shaft 601 is hollow and a second auxiliary blade 602 for guiding the water flow outward is installed on the outside. A docking groove 603 is opened at the upper end of the mating shaft 601. The docking groove 603 is inserted and docked with the docking chuck 4083. A plurality of circulation blades 604 for guiding the water flow upward are installed on the outside of the mating shaft 601.

[0070] In order to enhance the cleaning effect, when the connecting main rod 408 rotates, the mating groove 603 and the docking chuck 4083 are interlaced and docked to drive the matching shaft 601 to rotate, wherein the guide spiral blade 4085 is used to discharge the middle water flow downward, and the water flow is diffused to the lower water storage tank 6 under the guidance of the second auxiliary blade 602, and then the circulation blade 604 is used to discharge the water flow outside the lower water storage tank 6 upward, so that the water flow will flush and clean the MABR reaction membrane 501 from bottom to top, and then the water flow is guided to the connecting main rod 408 to realize circulation with the assistance of the first auxiliary blade 305. Through the above structure, the MABR reaction membrane 501 can be regularly self-cleaned to avoid the problem of excessive accumulation of impurities on the surface of the MABR reaction membrane 501, which leads to a decrease in the subsequent aeration reaction effect.

[0071] The working principle of a roll-type MABR aeration reactor:

[0072] When in use, the MABR reaction membrane 501 and the support net 502 are first wound onto the fixed winding plate 407 to achieve preliminary positioning, and then the knob 4014 is turned to rotate the adjusting screw rod 4013. During the rotation of the adjusting screw rod 4013, the roll-shaped groove 402 is used to limit the roll-shaped slide plate 403, so that when the adjusting screw rod 4013 and the connecting screw sleeve 4012 are threadedly matched, the height position of the roll-shaped slide plate 403 is adjusted, and then the matching clamping block 405 is moved up. When the matching clamping block 405 moves up, it will contact the guide slope 4021. Under the guidance of the guide slope 4021, the sliding seat 404 will adjust its position, so that the matching clamping block 405 will be close to the fixed winding plate 407, so as to achieve the clamping installation of the combined membrane layer 504 in the reaction component 5;

[0073] After installation, the first socket 4101 and the second socket 4112 can be docked with both ends of the reaction assembly 5, and one end of the reaction assembly 5 is blocked under the action of the second clamping plate 4113, while the first clamping plate 4104 temporarily fixes the other end of the reaction assembly 5 to ensure that the oxygen discharged from the subsequent air intake pipe 4103 can enter the ventilation channel 503 in the reaction assembly 5 to achieve stable air supply operation, and then the installed placement ring 409 is placed on the upper side of the support bearing 8 for subsequent rotation;

[0074] Then, the sealed upper cover 2 is closed, wherein the first connecting seat 306 and the second connecting seat 4081 are interlaced and docked, so that the driving component 3 is connected to the placement component 4, and finally the liquid inlet pipe 101 enters the sewage, and the air connection pipe 303 is connected to the external air pump to transport oxygen to realize the aeration operation;

[0075] After aeration for a certain period of time, in order to prevent impurities from clogging the surface of the MABR reaction membrane 501, the first connection seat 306 can be driven to rotate by starting the hollow shaft motor 302, and the second connection seat 4081 can be driven to rotate accordingly, so as to realize the overall rotation of the connecting main rod 408. Under the rotation of the connecting main rod 408, the roll-type bracket 401 and the reaction component 5 installed inside thereof are also rotated. Under the action of rotation, water will flow into the inside, wherein the roll-type design of the MABR reaction membrane 501 is utilized, so that the water flow will gradually flush inward, and the impurities on the surface of the MABR reaction membrane 501 will be discharged;

[0076] During self-cleaning, the guide spiral blade 4085 is used to discharge the middle water flow downward, and the water flow is diffused to the lower water storage tank 6 under the guidance of the second auxiliary blade 602. Then, the circulation blade 604 is used to discharge the water flow outside the lower water storage tank 6 upward, so that the water flow will flush and clean the MABR reaction membrane 501 from bottom to top.
