Description

Technical Field

[0001] This invention belongs to the field of anaerobic membrane technology, specifically an anaerobic membrane bioreactor for treating brine shrimp farming wastewater. Background Technology

[0002] The water containing various substances discharged from the breeding pond after the brine shrimp breeding is completed is called tailwater. These substances include brine shrimp excrement, uneaten feed, metabolic products, and chemical substances added during the breeding process. In order to avoid environmental pollution and to consider recycling and reuse, tailwater needs to be treated. Generally, tailwater treatment is carried out by using an anaerobic membrane bioreactor, which is divided into external and submerged types.

[0003] Submerged anaerobic membrane bioreactors utilize flat-plate anaerobic membranes to intercept impurities in wastewater, achieving solid-liquid separation and purifying effluent. However, existing reactors lack the ability to quickly and easily adjust the position of the flat-plate anaerobic membrane, hindering their ability to adapt to varying water quality. Water quality changes refer to the different amounts of impurities present in water flowing at different velocities. Without adjusting the membrane position accordingly, not only is the reactor's treatment efficiency reduced, but prolonged exposure of the flat-plate anaerobic membrane to high-velocity flow also leads to excessive impurities, shortening its lifespan and limiting its operational capabilities.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] (1) The locking tooth block can be moved upward by the distance control and displacement component, so that it no longer meshes with the displacement rack, thereby releasing the limiting setting on the T-shaped substrate. At this time, by moving the flat plate anaerobic membrane, it can be limited to move within the frame structure, thereby adjusting the position of the flat plate anaerobic membrane. Through the above description, the position of the flat plate anaerobic membrane can be adjusted conveniently and quickly, so that the spacing between several flat plate anaerobic membranes is in a controllable state. This allows the anaerobic membrane bioreactor for treating brine shrimp farming tailwater to flexibly respond to different water quality changes and flow rate conditions. The position of the membrane can be adjusted according to the different impurities, thereby improving the treatment efficiency of the reactor and avoiding the flat plate anaerobic membrane from being in a high flow rate area for a long time, which would cause it to be damaged by too many impurities. This improves the service life of the flat plate anaerobic membrane and further reduces the limitations of the reactor during use.

[0017] (2) The continuous rotation of the drive cam causes the reciprocating rack to move in a reciprocating state. When the reciprocating rack moves down, it meshes with the reciprocating gear and rotates, causing the gas storage tube on it to rotate, which drives several high-pressure nozzles to rotate, thereby adjusting the working angle of several high-pressure nozzles and increasing the application range of several high-pressure nozzles. When the reciprocating rack moves back to its original position, it meshes with the reciprocating gear and rotates back to its original position, causing several high-pressure nozzles to rotate back to their original position, so that the high-pressure nozzles can clean different positions of the flat anaerobic membrane during use, reducing the limitations of the reactor during use, and improving the cleaning effect of the flat anaerobic membrane, thus improving the effect of the reactor during use.

[0018] (3) Since the air pressure plate moves back and forth, several high-pressure nozzles continuously spray high-pressure gas onto the surface of the flat anaerobic membrane, which impacts the impurities adhering to the surface of the flat anaerobic membrane, loosening the impurities and reducing their adhesion strength. This process is repeated to blow off the impurities from the flat anaerobic membrane, cleaning the surface of the flat anaerobic membrane during its adjustment process, reducing the workload of the staff, and also reducing the limitations of the reactor during use. It is worth mentioning that the high-pressure nozzles can also be used in conjunction with water flow to thoroughly wash away the loosened pollutants, which not only facilitates cleaning by the staff but also improves the cleaning efficiency of the flat anaerobic membrane, thus reducing the cleaning time.

[0019] (4) By moving the adjusting slider, it moves to the upper limit of the adjusting column, thereby putting the compression spring in a buffer state. Since the displacement rack is set on the adjusting slider and is closely engaged with several locking teeth, it can be understood that several flat anaerobic membranes are set on several locking teeth. When the adjusting slider moves, it will drive the displacement rack to move and make the engaged locking teeth move together, thereby driving several flat anaerobic membranes to move synchronously. During the movement, the spacing between several flat anaerobic membranes will not change, thus making the entire flat anaerobic membrane move. This makes it convenient for staff to adjust the position of the entire flat anaerobic membrane according to different water quality changes, reducing the limitations of the reactor during use. At the same time, when the position of the entire flat anaerobic membrane moves synchronously, it is convenient for staff to maintain other components installed at several flat anaerobic membranes inside the reactor, improving the reactor's performance. This makes it convenient for the entire flat anaerobic membrane to treat effluent at different locations, improving the performance of the flat anaerobic membrane. Attached Figure Description

[0034] 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. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0035] Implementation examples, by Figures 1 to 11The present invention includes a frame structure 1, within which a plurality of flat anaerobic membranes 2 are disposed; each of the flat anaerobic membranes 2 is provided with a distance control and adaptation component, which is used to adjust the position of the flat anaerobic membranes 2 within the frame structure 1; each distance control and adaptation component includes two displacement racks 3 located opposite each other at the top of the frame structure 1, and the plurality of flat anaerobic membranes 2 are linearly arranged along the grooves of the displacement racks 3; each displacement rack 3 is provided with an overall adjustment unit, which is used to adjust the plurality of flat anaerobic membranes 2 The overall orientation; a T-shaped substrate 4 is installed on the top of the flat anaerobic membrane 2, and an airflow removal mechanism is also provided on the T-shaped substrate 4 to remove impurities adsorbed on the surface of the flat anaerobic membrane 2; two positioning columns 5 are symmetrically installed on the top of the T-shaped substrate 4, and positioning blocks 6 are slidably connected to the positioning columns 5; a positioning spring 7 is sleeved on the positioning column 5, and a positioning limiting plate 8 is connected to one end of the positioning spring 7. The positioning limiting plate 8 is installed at the end of the positioning column 5 away from the T-shaped substrate 4; the other end of the positioning spring 7... One end is connected to the positioning block 6; the opposite faces of the two positioning blocks 6 are connected to a handle 9, and an L-shaped rack 10 is installed on the side of the handle 9; a directional slider 55 is installed on the left and right sides of the flat anaerobic membrane 2, and the two directional sliders 55 are slidably connected to directional grooves 56 provided on opposite sides inside the frame structure 1; the directional grooves 56 are arranged parallel to the displacement rack 3; distance control blocks 11 are installed on both sides of the positioning blocks 6, and a distance control sliding column 12 is connected through the top of the distance control block 11 to control the distance. The sliding column 12 and the distance control block 11 are slidably engaged; the two distance control sliding columns 12 are connected to a distance control T-plate 13 at the end near the flat anaerobic membrane 2, and a locking tooth block 14 is installed on the distance control T-plate 13. The tooth groove on the displacement rack 3 is located on the moving path of the locking tooth block 14, and the two are meshed; a distance control spring 15 is sleeved on the distance control sliding column 12. One end of the distance control spring 15 is fixedly connected to the distance control block 11, and the other end is connected to a distance control limiting plate 16. The distance control limiting plate 16 is installed at the end of the distance control sliding column 12 away from the flat anaerobic membrane 2.

[0036] By pulling the handle 9 upwards, the two positioning blocks 6 on it move upwards from their respective upper limits on the two positioning posts 5, causing the positioning spring 7 to be in a buffered state. This, in turn, causes the distance control block 11 on the positioning block 6 to move upwards. Since the distance control spring 15 was originally in a buffered state, the upward movement of the distance control block 11 causes the distance control spring 15 to gradually reset. Once the distance control spring 15 has reset, pulling the distance control block 11 upwards continuously will cause the locking tooth block 14 to move upwards, preventing it from engaging the displacement rack 3, thus releasing the limiting setting on the T-shaped substrate 4. At this point, by moving the flat anaerobic membrane 2, it can be limited and moved within the frame structure 1, thereby achieving... By adjusting the position of the flat-plate anaerobic membrane 2, as described above, the position of the flat-plate anaerobic membrane 2 can be conveniently and quickly adjusted, making the spacing between several flat-plate anaerobic membranes 2 controllable. This allows the anaerobic membrane bioreactor for treating brine shrimp farming wastewater to flexibly respond to different water quality changes and flow rates. The position of the membrane can be adjusted according to different impurities, improving the reactor's treatment efficiency and preventing the flat-plate anaerobic membrane 2 from being damaged by excessive impurities due to prolonged exposure to high flow rates. This extends the service life of the flat-plate anaerobic membrane 2 and further reduces the limitations of the reactor during use.

[0037] It is worth mentioning that when the flat anaerobic membrane 2 is moving, the directional sliders 55 on both sides move within the directional grooves 56 to limit the movement of the flat anaerobic membrane 2, thereby preventing the flat anaerobic membrane 2 from shaking or deviating from its installation position, thus improving the installation effect and stability of the flat anaerobic membrane 2 during movement.

[0038] After the position of the flat-plate anaerobic membrane 2 is adjusted, the handle 9, which was originally pulled outward, is released, causing the positioning spring 7 to return to its original position. This return of the positioning spring 7 then moves the positioning block 6 back to its original position, causing the control block 11 to move closer to the top of the flat-plate anaerobic membrane 2. Under the action of the control slide 12 and the control spring 15, the control block 11 moves the locking tooth block 14 downward, engaging with the displacement rack 3 during its movement. This limits the T-shaped substrate 4 on the flat-plate anaerobic membrane 2, preventing displacement due to non-human factors such as excessive impact from water flow. This improves the performance of the flat-plate anaerobic membrane 2 within the reactor, enhancing its effectiveness in treating wastewater and further improving its stability during use.

[0039] It is worth mentioning that since the strength of the positioning spring 7 is greater than that of the control spring 15, and the positioning spring 7 has not yet returned to its original position after the locking tooth block 14 engages with the displacement rack 3, the positioning spring 7 continues to move and reset, and the locking tooth block 14 is limited and cannot move further down, so the control block 11 moves to the upper limit of the control slide column 12, so that the control spring 15 is in a buffer state, thereby increasing the pressure applied to the locking tooth block 14, improving the contact strength between it and the displacement rack 3, and preventing the locking tooth block 14 from dislodging due to non-human factors when engaging with the displacement rack 3, further improving the safety of the flat anaerobic membrane 2 during use.

[0040] The airflow removal mechanism of this embodiment includes an active base plate 17 mounted on a T-shaped base plate 4. A drive shaft 18 is mounted on the active base plate 17, and a rotating gear 19 is mounted on the drive shaft 18. The rotating gear 19 meshes with an L-shaped rack 10. A gear disk 20 is also mounted on the end of the drive shaft 18 away from the active base plate 17. The gear disk 20 meshes with a drive gear 21, and the drive gear 21 is also equipped with a rotary steering mechanism. A movable column 22 is mounted on the side of the gear disk 20. A movable cross block 23 is slidably connected to the movable column 22. Two guide slides 24 are symmetrically mounted on the top of the movable cross block 23. The two guide slides 24 are slidably connected to a guide base plate 25, which is fixedly mounted on the T-shaped base plate 4. A pneumatic square plate 26 is mounted on the bottom of the movable cross block 23. A retaining frame 27 is mounted on the T-shaped substrate 4. A rectangular box 28 is installed inside the retaining frame 27. A rectangular slot 29 is provided inside the rectangular box 28. The rectangular slot 29 has the same shape as the air pressure plate 26. One side of the rectangular slot 29 extends to the top of the rectangular box 28. The air pressure plate 26 is located inside the rectangular slot 29 and the two are slidably engaged. A valve-type air inlet pipe 30 is installed on the side of the rectangular box 28. A valve-type air outlet pipe 31 is installed at the bottom of the rectangular box 28. The end of the valve-type air outlet pipe 31 is connected to a gas storage pipe 32. Retaining substrates 33 are installed on both ends of the gas storage pipe 32. The opposite surfaces of the two retaining substrates 33 are connected to the retaining frame 27. Several high-pressure nozzles 34 are installed on the gas storage pipe 32. The output ends of the high-pressure nozzles 34 face the flat anaerobic membrane 2.

[0041] When the distance control and adjustment component adjusts the position of the flat anaerobic membrane 2, the handle 9 needs to be pulled up, causing the L-shaped rack 10 on it to move upwards synchronously, engaging with the rotating gear 19 and causing it to rotate. Under the action of the transmission shaft 18, the gear disk 20 rotates, causing the positioning column 22 to rotate with the gear disk 20. This causes the positioning column 22 to slide back and forth within the positioning block 23, allowing the positioning block 23 to move back and forth on the guide plate 25 via the guide slide post 24, thereby driving the pneumatic square plate 26 to move back and forth. When the pneumatic square plate 26 moves downwards at the rectangular slot 29 within the rectangular box 28... Because the valve at the valve-type air inlet pipe 30 is closed when the pressure plate 26 moves downward, while the valve at the valve-type air outlet pipe 31 is open, the gas between the pressure plate 26 and the bottom surface of the rectangular box 28 enters the gas storage pipe 32 through the valve-type air outlet pipe 31. Under the action of several high-pressure nozzles 34, the gas is applied to the contact surface between the flat anaerobic membrane 2 and the wastewater flow. When the pressure plate 26 moves upward, the valve-type air outlet pipe 31 is closed, while the valve-type air inlet pipe 30 is open, thus allowing external gas to be drawn into the rectangular box 28 through the valve-type air inlet pipe 30. During the next downward movement of the pressure plate 26, the inhaled gas acts on the flat anaerobic membrane 2. Because the pressure plate 26 moves reciprocally, several high-pressure nozzles 34 continuously spray high-pressure gas onto the surface of the flat anaerobic membrane 2, creating an impact force on impurities adhering to its surface, loosening them, and reducing their adhesion strength. This process repeats, blowing off impurities from the flat anaerobic membrane 2. This effectively cleans the surface of the flat anaerobic membrane 2 during its repositioning process, reducing the workload for workers. This reduces workload and also lowers the limitations of the reactor during use. It's worth mentioning that the high-pressure nozzle 34, when used in conjunction with water flow, can thoroughly wash away loose contaminants, facilitating cleaning by staff and improving the cleaning efficiency of the flat-plate anaerobic membrane 2, thus reducing cleaning time. Furthermore, when the distance control and adjustment component is used to adjust the position of the flat-plate anaerobic membrane 2, releasing the handle 9 and causing the L-shaped rack 10 to reset and move, the high-pressure nozzle 34 continues to generate high-pressure gas and act on the flat-plate anaerobic membrane 2, further enhancing the cleaning effect.

[0042] The overall adjustment unit of this embodiment includes two adjusting sliders 35 symmetrically installed on the side of the displacement rack 3 near the flat anaerobic membrane 2. The two adjusting sliders 35 are slidably connected to an adjusting column 36. Adjusting base plates 37 are installed at both ends of the adjusting column 36. The bottom of the two adjusting base plates 37 are connected to a supporting cross column 38, which is installed on the top of the frame structure 1. Two symmetrically arranged compression springs 39 are sleeved on the adjusting column 36. One end of the compression spring 39 is fixedly connected to the adjusting base plate 37, and the other end is fixedly connected to the adjusting slider 35. The side of the adjusting column 36 away from the T-shaped base plate 4 The device is provided with several horizontally equidistantly arranged adjusting lock slots 40; two limiting cylinders 41 are symmetrically installed on the side of the adjusting slider 35 away from the T-shaped base plate 4, and limiting slide plates 42 are slidably connected to the limiting cylinders 41. The tops of the two limiting slide plates 42 are connected to an adjusting lock block 43, which passes through the side of the adjusting slider 35 and is connected to one of the adjusting lock slots 40; a limiting spring 44 is sleeved on the limiting cylinder 41, one end of the limiting spring 44 is connected to the limiting slide plate 42, and the other end is connected to a limiting circular plate 45, which is installed on the end of the limiting cylinder 41 away from the adjusting slider 35;

[0043] When the positions of several flat anaerobic membranes 2 are adjusted and then the overall position needs to be adjusted (i.e., when the spacing between the several flat anaerobic membranes 2 remains unchanged and they need to be moved as a whole), this is usually due to changes in water composition or concentration, or when a process needs to be added and the layout needs to be rearranged. The position of the several flat anaerobic membranes 2, i.e., the whole, needs to be adjusted. By pulling the adjusting locking block 43 outward, it moves to the upper limit of the limiting cylinder 41 via the limiting slide plate 42, causing the limiting spring 44 to be in a buffered state. This causes the adjusting locking block 43 to disengage from the adjusting slider 35 and no longer connect to the adjusting locking groove 40, thus releasing the limiting setting on the adjusting slider 35. Then, by moving the adjusting slider 35, it moves to the upper limit of the adjusting square column 36, causing the compression spring 39 to be in a buffered state. Since the displacement rack 3 is set on the adjusting slider 35, and the displacement rack 3 is tightly connected to several locking teeth 14... The close fit can be understood as several flat anaerobic membranes 2 being individually set on several locking and shifting tooth blocks 14. When the adjusting slider 35 moves, it will drive the displacement rack 3 to move, and cause the meshing locking and shifting tooth blocks 14 to move together, thereby driving several flat anaerobic membranes 2 to move synchronously. During the movement, the spacing between several flat anaerobic membranes 2 does not change, thus allowing the entire flat anaerobic membrane 2 to move. This makes it convenient for staff to adjust the position of the entire flat anaerobic membrane 2 according to different water quality changes, reducing the limitations of the reactor during use. At the same time, when the position of the entire flat anaerobic membrane 2 moves synchronously, it is convenient for staff to maintain other components installed on several flat anaerobic membranes 2 inside the reactor, improving the reactor's performance. This makes it easy for the entire flat anaerobic membrane 2 to treat effluent at different locations, improving the performance of the flat anaerobic membrane 2.

[0044] It is worth mentioning that after the positions of all the flat-plate anaerobic membranes 2 are adjusted, the adjusting lock block 43 is released. The limiting spring 44 resets the adjusting lock block 43, allowing it to pass through the adjusting slider 35 and connect with one of the adjusting lock slots 40. This fixes the displacement rack 3 on the adjusting slider 35 in its current position, preventing the flat-plate anaerobic membrane 2 from shaking or dislodging during use, thus improving the performance and stability of the flat-plate anaerobic membrane 2. At the same time, when the adjusting slider 35 is limited, the compression spring 39, which is in a buffer state, cannot reset. The resulting elastic force acts on the adjusting slider 35, thereby strengthening the contact strength between the adjusting lock slot 40 and the adjusting lock block 43. This prevents the adjusting lock block 43 from moving or shaking due to non-human factors during use, improving the performance of the reactor and the stability of the flat-plate anaerobic membrane 2 during use.

[0045] The rotary steering device of this embodiment includes a drive shaft 46 mounted on a drive gear 21, a drive base plate 47 connected to the drive shaft 46, the drive base plate 47 connected to the top of a fixed base plate 33, two L-shaped base plates 48 mounted on the bottom of the fixed base plate 33, a rotary cylinder 49 penetrating the top of the L-shaped base plate 48, the rotary cylinder 49 slidingly engaging with the L-shaped base plate 48; a rotary cross block 50 connected to the top of the two rotary cylinders 49; a drive cam 51 connected to the end of the drive shaft 46 away from the drive gear 21, the top of the rotary cross block 50 located at the rotation path of the side wall of the drive cam 51; a rotary spring 52 sleeved on the rotary cylinder 49, one end of the rotary spring 52 connected to the L-shaped base plate 48, the other end connected to the rotary cross block 50, a rotary rack 53 mounted on both sides of the rotary cross block 50, the rotary rack 53 meshing with a rotary gear 54, and two rotary gears 54 mounted at both ends of the gas storage pipe 32;

[0046] When the gear disk 20 rotates, it meshes with the drive gear 21, causing the high-pressure nozzle 34 to work on the surface of the flat anaerobic membrane 2. The rotation of the drive gear 21, under the action of the drive shaft 46, drives the drive cam 51 to rotate, causing its sidewall to continuously contact the top of the repeating horizontal block 50. When the sidewall of the drive cam 51 contacts the top of the repeating horizontal block 50, it exerts downward pressure, causing the repeating horizontal block 50 to move on the L-shaped substrate 48 via the repeating cylinder 49. This puts the repeating spring 52 in a buffered state, thereby driving the repeating rack 53 downward. When the sidewall of the drive cam 51 no longer contacts the top of the repeating horizontal block 50, it is no longer subjected to downward pressure. The repeating spring 52 then resets and gradually moves the repeating horizontal block 50 back to its original position. This causes the reciprocating rack 53 to move upwards, and the continuous rotation of the driving cam 51 causes the reciprocating rack 53 to move back and forth. When the reciprocating rack 53 moves downwards, it meshes with the reciprocating gear 54 and rotates, causing the gas storage tube 32 on it to rotate, which in turn drives several high-pressure nozzles 34 to rotate, thereby adjusting the working angle of the high-pressure nozzles 34 and increasing their range of use. When the reciprocating rack 53 moves back to its original position, it meshes with the reciprocating gear 54 and rotates back to its original position, causing the high-pressure nozzles 34 to rotate back to their original position. This allows the high-pressure nozzles 34 to clean different positions of the flat-plate anaerobic membrane 2 during use, reducing the limitations of the reactor during use and improving the cleaning effect of the flat-plate anaerobic membrane 2, thus improving the overall performance of the reactor.
