Description

Technical Field

[0001] The invention belongs to the technical field of anaerobic membranes, in particular to an anaerobic membrane bioreactor for treating Artemia aquaculture tail water. Background Art

[0002] The water containing various substances discharged from the breeding pond after the Artemia is completed is the tail water. These substances include Artemia excrement, leftover bait, metabolites and chemical substances added during the breeding process. In order to avoid the pollution of the tail water to the environment and consider recycling and reuse, the tail water needs to be treated. Generally, the tail water is treated by using anaerobic membrane bioreactors, and anaerobic membrane bioreactors are divided into external and submerged types.

[0003] Among them, the submerged anaerobic membrane bioreactor uses a flat anaerobic membrane to intercept impurities in sewage, thereby achieving solid-liquid separation and achieving the effect of tail water purification. However, during the use of the existing reactor, it is impossible to quickly and conveniently adjust the position of the flat anaerobic membrane, resulting in the reactor being unable to flexibly respond to different water quality changes. Water quality changes refer to the different amounts of impurities mixed in water bodies at different flow rates. If the position of the membrane cannot be adjusted accordingly according to the different amounts of impurities, not only will the treatment efficiency of the reactor be reduced, but the flat anaerobic membrane will also be exposed to excessive amounts of impurities if it is in a fast flow area for a long time, thereby reducing the service life of the flat anaerobic membrane and making the reactor more limited when used.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] (1) The distance control and displacement assembly is used to drive the locking tooth block to move upward so that it no longer engages with the displacement rack, thereby releasing the limit setting of the T-shaped base plate. At this time, the flat-plate anaerobic membrane is moved 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, so that the anaerobic membrane bioreactor for treating Artemia aquaculture tail water can be flexibly responded to according to different water quality changes and flow rate conditions, and the position of the membrane can be adjusted accordingly according to the different impurities, thereby improving the treatment efficiency of the reactor, avoiding the flat-plate anaerobic membrane from being in a fast flow area for a long time, causing it to be damaged by excessive impurities, and improving the service life of the flat-plate anaerobic membrane, thereby further reducing the limitations of the reactor during use;

[0017] (2) The continuous rotation of the driving cam causes the double-acting rack to be in a reciprocating state; when the double-acting rack moves downward, it meshes with the double-acting gear and rotates, so that the gas storage tube on it rotates, which can drive the rotation of a plurality of high-pressure nozzles, thereby adjusting the operating angles of the plurality of high-pressure nozzles and increasing the use range of the plurality of high-pressure nozzles; when the double-acting rack is reset, it meshes with the double-acting gear and resets and rotates, so that the plurality of high-pressure nozzles are reset and rotated, so that the high-pressure nozzles can clean different positions of the flat-plate anaerobic membrane when in use, reducing the limitations of the reactor when in use, and at the same time improving the cleaning effect of the flat-plate anaerobic membrane, so that the effect of the reactor when in use is improved;

[0018] (3) Since the air pressure square plate is reciprocating, a number of high-pressure nozzles can continuously spray high-pressure gas to act on the surface of the flat-plate anaerobic membrane, thereby exerting an impact force on impurities adhering to the surface of the flat-plate anaerobic membrane, loosening the impurities and reducing the strength of the impurities adhering to the flat-plate anaerobic membrane. The impurities on the flat-plate anaerobic membrane can be blown off by the reciprocating movement, and the impurities adhering to the surface of the flat-plate anaerobic membrane can be cleaned during the process of adjusting the position of the flat-plate anaerobic membrane, thereby reducing the workload of the staff and the limitations of the reactor during use. It is worth mentioning that the high-pressure nozzle can also cooperate with the water flow to completely wash away the loosened pollutants during use, which is not only convenient for the staff to clean, but also improves the cleaning efficiency of the flat-plate anaerobic membrane, thereby reducing the cleaning time.

[0019] (4) By moving the adjustment slider, the adjustment slider is moved to the upper limit of the adjustment square column, and then the extrusion spring is placed in a buffer state. Since the displacement rack is arranged on the adjustment slider, and the displacement rack is tightly fitted with a plurality of locking and shifting tooth blocks, it can be understood that a plurality of flat-plate anaerobic membranes are arranged one by one on a plurality of locking and shifting tooth blocks. When the adjustment slider moves, the displacement rack is driven to move, and the meshing locking and shifting tooth blocks are moved together, thereby driving a plurality of flat-plate anaerobic membranes to move synchronously, and the spacing between the plurality of flat-plate anaerobic membranes will not change during the movement, thereby allowing the entire flat-plate anaerobic membrane to move, making it convenient for the staff to adjust the position of the entire flat-plate anaerobic membrane according to different water quality changes, thereby reducing the limitations of the reactor during use. At the same time, when the position of the entire flat-plate anaerobic membrane is moved synchronously, it is convenient for the staff to maintain other components installed at the plurality of flat-plate anaerobic membranes inside the reactor, thereby improving the use effect of the reactor, thereby making it convenient for the entire plurality of flat-plate anaerobic membranes to treat tail water at different positions, thereby improving the use effect of the flat-plate anaerobic membranes.

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0035] Example, by Figures 1 to 11The present invention comprises a frame structure 1, in which a plurality of flat anaerobic membranes 2 are arranged; a plurality of the flat anaerobic membranes 2 are provided with a distance control and displacement assembly, which is used to adjust the position of the flat anaerobic membrane 2 in the frame structure 1; the distance control and displacement assembly comprises two displacement racks 3 relatively located at the top of the frame structure 1, and a plurality of the flat anaerobic membranes 2 are linearly arranged along the tooth groove direction of the displacement rack 3; an overall positioning unit is provided on the displacement rack 3, and the overall positioning unit is used to adjust the position of the plurality of flat anaerobic membranes 2 The overall direction of the flat anaerobic membrane 2 is installed with a T-shaped substrate 4 on the top, and an airflow removal mechanism is also provided on the T-shaped substrate 4, which is used to remove impurities adsorbed on the surface of the flat anaerobic membrane 2; two positioning square columns 5 are symmetrically installed on the top of the T-shaped substrate 4, and a positioning block 6 is slidably connected to the positioning square column 5; a positioning spring 7 is sleeved on the positioning square column 5, and one end of the positioning spring 7 is connected to a positioning limit plate 8, and the positioning limit plate 8 is installed at the end of the positioning square 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 surfaces of the two positioning blocks 6 are connected with 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 respectively slidably connected with the directional slide grooves 56 provided on the opposite sides of the frame structure 1; the directional slide grooves 56 are arranged parallel to the displacement rack 3; the two sides of the positioning block 6 are installed with a distance control horizontal block 11, and the top of the distance control horizontal block 11 is connected with a distance control sliding column 12, and the distance control The sliding column 12 is slidably matched with the distance control cross block 11; the two distance control sliding columns 12 are connected to a distance control T-plate 13 at one end close to 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 and matched; the distance control sliding column 12 is sleeved with a distance control spring 15, one end of the distance control spring 15 is fixedly connected to the distance control cross block 11, and the other end is connected to a distance control limit plate 16, and the distance control limit 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 upward, the two positioning blocks 6 on it are respectively moved up at the upper limit positions of the two positioning square columns 5, so that the positioning spring 7 is in a buffering state, and then the distance control cross block 11 on the positioning block 6 is moved up. Since the distance control spring 15 is originally in a buffering state, the distance control spring 15 is gradually reset by the upward movement of the distance control cross block 11. When the distance control spring 15 is reset, the continuous upward movement of the distance control cross block 11 can drive the lock shift tooth block 14 to move up, so that it no longer meshes with the displacement rack 3, thereby releasing the limit setting of the T-shaped substrate 4. At this time, the flat anaerobic membrane 2 is moved to limit the movement in the frame structure 1, thereby obtaining By adjusting the position of the flat anaerobic membrane 2, the above description makes it possible to conveniently and quickly adjust the position of the flat anaerobic membrane 2, so that the spacing between a number of flat anaerobic membranes 2 is in a controllable state, so that the anaerobic membrane bioreactor for treating Artemia aquaculture tail water can be flexibly responded to according to different water quality changes and flow rate conditions, and the position of the membrane can be adjusted accordingly according to the different impurities, thereby improving the treatment efficiency of the reactor, avoiding the flat anaerobic membrane 2 from being in a fast flow area for a long time, causing it to be damaged by excessive impurities, and improving the service life of the flat anaerobic membrane 2, thereby further reducing 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 thereof are limitedly moved in the directional slide grooves 56 to limit the movement of the flat anaerobic membrane 2, thereby preventing the flat anaerobic membrane 2 from shaking during movement, which may cause deviation in its installation position, thereby improving the installation effect of the flat anaerobic membrane 2 and the stability during movement;

[0038] When the position of the flat anaerobic membrane 2 is adjusted, the positioning spring 7 is no longer stressed and resets by loosening the handle 9 that was originally pulled outward. The positioning spring 7 is reset to drive the positioning block 6 to reset and move, so that the distance control cross block 11 is reset and moved, that is, it moves close to the top of the flat anaerobic membrane 2. The distance control cross block 11 drives the lock shift tooth block 14 to move downward under the action of the distance control slide column 12 and the distance control spring 15, so that it engages with the displacement rack 3 during the movement, thereby limiting the T-shaped base plate 4 on the flat anaerobic membrane 2, avoiding the displacement of the flat anaerobic membrane 2 due to non-human factors during use, such as excessive impact force of water flow on the flat anaerobic membrane 2, thereby improving the use effect of the flat anaerobic membrane 2 in the reactor, so that the effect of the reactor in treating tail water is improved; thereby further improving the stability of the flat anaerobic membrane 2 when in use;

[0039] It is worth mentioning that since the strength of the positioning spring 7 is greater than that of the distance control spring 15, and the positioning spring 7 has not yet returned to its position after the locking tooth block 14 is engaged with the displacement rack 3, the positioning spring 7 continues to return to its original position, and the locking tooth block 14 is limited and cannot continue to move downward, so that the distance control cross block 11 is limited and moved on the distance control sliding column 12, so that the distance control spring 15 is in a buffering state, thereby increasing the pressure on the locking tooth block 14, and improving the contact strength between the locking tooth block 14 and the displacement rack 3, thereby avoiding the locking tooth block 14 from being dislocated due to non-human factors when it is engaged with the displacement rack 3, and further improving the safety of the flat anaerobic membrane 2 when in use.

[0040] The airflow removal mechanism of this embodiment includes an active substrate 17 installed on a T-shaped substrate 4, a transmission shaft 18 is installed on the active substrate 17, a rotating gear 19 is installed on the transmission shaft 18, and the rotating gear 19 is meshed and connected with the L-shaped rack 10; the end of the transmission shaft 18 away from the active substrate 17 is also installed with a gear disc 20, the gear disc 20 is meshed and connected with a driving gear 21, and a compound rotation diverter is also provided on the driving gear 21; a positioning column 22 is installed on the side of the gear disc 20, a positioning cross block 23 is slidably connected to the positioning column 22, and two guide slides 24 are symmetrically installed on the top of the positioning cross block 23, and the two guide slides 24 are slidably connected to a guide substrate 25, and the guide substrate 25 is fixedly installed on the T-shaped substrate 4; a pneumatic square plate 26 is installed at the bottom of the positioning cross block 23; A retaining frame 27 is installed on the T-shaped substrate 4, and a rectangular box 28 is installed in the retaining frame 27. A rectangular notch 29 is provided in the rectangular box 28, and the rectangular notch 29 has the same shape as the air pressure square plate 26; one side of the rectangular notch 29 extends to the top of the rectangular box 28; the air pressure square plate 26 is located in the rectangular notch 29 and the two are slidably matched; 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, and the end point of the valve-type air outlet pipe 31 is connected to a gas storage circular tube 32, and retaining substrates 33 are installed on both ends of the gas storage circular tube 32, and the opposite surfaces of the two retaining substrates 33 are connected to the retaining frame 27; a plurality of high-pressure nozzles 34 are installed on the gas storage circular tube 32, and the output end of the high-pressure nozzle 34 faces the flat anaerobic membrane 2;

[0041] When the distance control and displacement assembly is adjusting the position of the flat anaerobic membrane 2, the handle 9 needs to be pulled up to synchronously move the L-shaped rack 10 thereon upward, so that it meshes with the rotating gear 19 and rotates, so that the gear disc 20 is driven to rotate under the action of the transmission shaft 18, so that the positioning cylinder 22 rotates with the gear disc 20, so that the positioning cylinder 22 slides back and forth in the positioning cross block 23, so that the positioning cross block 23 reciprocates on the guide base plate 25 through the guide slide column 24, thereby driving the air pressure square plate 26 to reciprocate; when the air pressure square plate 26 moves down at the rectangular notch 29 in the rectangular box 28, Since the valve at the valve-type air inlet pipe 30 is in a closed state when the air pressure square plate 26 moves downward, and the valve at the valve-type air outlet pipe 31 is opened, the gas between the air pressure square plate 26 and the inner bottom surface of the rectangular box 28 enters the gas storage round pipe 32 through the valve-type air outlet pipe 31, and the above-mentioned gas is applied to the contact surface between the flat anaerobic membrane 2 and the sewage flow under the action of a plurality of high-pressure nozzles 34; when the air pressure square plate 26 moves upward, the valve-type air outlet pipe 31 is closed at this time, and the valve-type air inlet pipe 30 is opened, so that the external gas can be sucked into the rectangular box 28 through the valve-type air inlet pipe 30 , and the inhaled gas acts on the flat anaerobic membrane 2 when the air pressure square plate 26 moves down next time. Since the air pressure square plate 26 moves back and forth, a plurality of high-pressure nozzles 34 can continuously spray high-pressure gas to act on the surface of the flat anaerobic membrane 2, so as to create an impact force on the impurities adhering to the surface of the flat anaerobic membrane 2, so that the impurities are loosened and the strength of the impurities adhering to the flat anaerobic membrane 2 is reduced. The impurities on the flat anaerobic membrane 2 can be blown off by reciprocating in this way, and the impurities adhering to the surface of the flat anaerobic membrane 2 during use can be cleaned during the process of adjusting the position of the flat anaerobic membrane 2, thereby reducing the staff's The working intensity is improved, and the limitations of the reactor when in use are reduced; it is worth mentioning that the high-pressure nozzle 34 can also cooperate with the water flow to completely wash away the loose pollutants when in use, which is not only convenient for the staff to clean, but also improves the cleaning efficiency of the flat-plate anaerobic membrane 2, so that the cleaning time can be reduced; at the same time, when the distance control and adaptive movement component releases the handle 9 after the position adjustment of the flat-plate anaerobic membrane 2 is completed and the L-shaped rack 10 is reset and moved, the high-pressure nozzle 34 continues to generate high-pressure gas and acts on the flat-plate anaerobic membrane 2 for use, thereby improving the cleaning effect of the flat-plate anaerobic membrane 2.

[0042] The overall positioning unit of this embodiment includes two adjusting sliders 35 symmetrically installed on the displacement rack 3 near the side of the flat anaerobic membrane 2. The two adjusting sliders 35 are slidably connected to an adjusting square column 36. Adjusting base plates 37 are installed at both ends of the adjusting square column 36. The bottoms of the two adjusting base plates 37 are commonly connected to a supporting cross column 38. The supporting cross column 38 is installed on the top of the frame structure 1. Two symmetrically arranged extrusion springs 39 are sleeved on the adjusting square column 36. One end of the extrusion 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 square column 36 away from the T-shaped base plate 4 A plurality of adjustment lock grooves 40 are arranged transversely and equidistantly through the adjustment slider 35; two limiting cylinders 41 are symmetrically installed on the side of the adjustment slider 35 away from the T-shaped base plate 4, and a limiting slide plate 42 is slidably connected to the limiting cylinder 41, and an adjustment lock block 43 is commonly connected to the top of the two limiting slide plates 42, and the adjustment lock block 43 passes through the side of the adjustment slider 35 and is connected to one of the adjustment lock grooves 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 the limiting circular plate 45, and the limiting circular plate 45 is installed on the end of the limiting cylinder 41 away from the adjustment slider 35;

[0043] When the positions of several flat-plate anaerobic membranes 2 need to be adjusted as a whole after the position adjustment is completed, that is, when the spacing between several flat-plate anaerobic membranes 2 remains unchanged and they need to be moved as a whole, it is usually because the water quality composition and concentration change or the process needs to be re-arranged, and the positions of several flat-plate anaerobic membranes 2, that is, a whole, need to be adjusted. By pulling the adjustment lock block 43 outward, it is moved on the upper limit of the limit cylinder 41 through the limit slide plate 42, so that the limit spring 44 is in a buffering state, so that the adjustment lock block 43 is separated from the adjustment slider 35 and is no longer connected to the adjustment lock groove 40, thereby releasing the limit setting of the adjustment slider 35. At this time, by moving the adjustment slider 35, it is moved on the upper limit of the adjustment square column 36, and then the extrusion spring 39 is in a buffering state. Moreover, since the displacement rack 3 is arranged on the adjustment slider 35, and the displacement rack 3 is tightly connected to several lock shift gear blocks 14 The close fit can be understood as that a plurality of flat anaerobic membranes 2 are arranged one by one on a plurality of locking and shifting tooth blocks 14. When the adjusting slider 35 moves, the displacement rack 3 is driven to move, and the meshing locking and shifting tooth blocks 14 are moved together, so that the plurality of flat anaerobic membranes 2 are driven to move synchronously, and the spacing between the plurality of flat anaerobic membranes 2 will not change during the movement, so that the entire flat anaerobic membrane 2 moves, which is convenient for the 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 together, it is convenient for the staff to maintain other components installed at the plurality of flat anaerobic membranes 2 inside the reactor, thereby improving the use effect of the reactor, so that the entire plurality of flat anaerobic membranes 2 are convenient to treat tail water at different positions, thereby improving the use effect of the flat anaerobic membrane 2;

[0044] It is worth mentioning that when the positions of the entire plurality of flat-plate anaerobic membranes 2 are adjusted, the adjusting lock block 43 is released, and the adjusting lock block 43 is reset by the reset of the limit spring 44, so that it passes through the adjusting slider 35 and is connected to one of the adjusting lock grooves 40, thereby fixing the displacement rack 3 on the adjusting slider 35 at the current position, avoiding the flat-plate anaerobic membrane 2 from shaking or dislocating during use, thereby improving the use effect and stability of the flat-plate anaerobic membrane 2; at the same time, when the adjusting slider 35 is limited, the extrusion spring 39 in the buffer state cannot be reset, and the elastic force brought about will act on the adjusting slider 35, thereby strengthening the contact strength between the adjusting lock groove 40 and the adjusting lock block 43, avoiding the adjustment lock block 43 from moving or shaking due to non-human factors during use, thereby improving the use effect of the reactor and the stability of the flat-plate anaerobic membrane 2 during use.

[0045] The compound rotation diverter of this embodiment includes a driving shaft 46 installed on the driving gear 21, and a driving substrate 47 is connected to the driving shaft 46. The driving substrate 47 is connected to the top of the fixed substrate 33. Two L-shaped substrates 48 are installed at the bottom of the fixed substrate 33. A compound cylinder 49 is connected to the top of the L-shaped substrate 48, and the compound cylinder 49 and the L-shaped substrate 48 are slidably matched; the tops of the two compound cylinders 49 are commonly connected to a compound cross block 50; the end of the driving shaft 46 away from the driving gear 21 is connected to a driving cam 51, and the top of the compound cross block 50 is located at the rotation path of the side wall of the driving cam 51; a compound spring 52 is sleeved on the compound cylinder 49, one end of the compound spring 52 is connected to the L-shaped substrate 48, and the other end is connected to the compound cross block 50. A compound rack 53 is installed on both sides of the compound cross block 50, and the compound rack 53 is meshed and connected with a compound gear 54. The two compound gears 54 are installed at both ends of the gas storage tube 32;

[0046] When the gear disc 20 rotates, it will mesh with the driving gear 21 to rotate. At this time, the high-pressure nozzle 34 is working toward the surface of the flat anaerobic membrane 2. The driving gear 21 rotates to drive the driving cam 51 under the action of the driving shaft 46, so that the side wall of the driving cam 51 continuously contacts the top of the compound-moving cross block 50 during rotation. When the side wall of the driving cam 51 contacts the top of the compound-moving cross block 50, it will cause downward pressure to the compound-moving cross block 50, so that the compound-moving cross block 50 moves on the L-shaped base plate 48 through the compound-moving cylinder 49, so that the compound-moving spring 52 is in a buffering state, thereby driving the compound-moving rack 53 to move downward. When the side wall of the driving cam 51 no longer contacts the top of the compound-moving cross block 50, it is no longer subjected to downward pressure, and the compound-moving cross block 50 is gradually driven to reset and move through the reset of the compound-moving spring 52. Thereby, the double-acting rack 53 moves upward, and the continuous rotation of the driving cam 51 causes the double-acting rack 53 to be in a reciprocating state; when the double-acting rack 53 moves downward, it engages with the double-acting gear 54 to rotate, so that the gas storage tube 32 thereon rotates, thereby driving the plurality of high-pressure nozzles 34 to rotate, thereby adjusting the operating angles of the plurality of high-pressure nozzles 34 and increasing the use range of the plurality of high-pressure nozzles 34; when the double-acting rack 53 is reset, it engages with the double-acting gear 54 to reset and rotate, so that the plurality of high-pressure nozzles 34 are reset and rotated, so that the high-pressure nozzles 34 can clean different positions of the flat-plate anaerobic membrane 2 when in use, thereby reducing the limitations of the reactor when in use, and at the same time improving the cleaning effect of the flat-plate anaerobic membrane 2, so that the effect of the reactor when in use is improved.
