Description

Technical Field

[0001] The present invention belongs to the technical field of bioreactors for algal growth, and specifically relates to a bioreactor for intelligently controlling algal growth. Background Art

[0002] Columnar bioreactors are often used for culturing algae. The columnar bioreactor is usually of a cylindrical structure and is vertically placed. This shape is beneficial to providing a large surface area to volume ratio in a limited space, providing more light and attachment space for algal growth, and also facilitating the flow and circulation of nutrient solution inside. The columnar bioreactor uses a transparent columnar structure to enable light to fully penetrate into the reactor interior, providing the light energy required for photosynthesis of algae. Algae absorb light energy through photosynthetic pigments such as chlorophyll, and convert carbon dioxide and water into organic matter and oxygen, thereby achieving growth and reproduction.

[0003] After the columnar bioreactor finishes culturing algae, it is necessary to discharge the wastewater inside. Since algae produce relatively large impurities during cultivation, such as algal cell aggregates, unconsumed solid nutrients, microbial metabolites, and biofilms. Since the columnar bioreactor is connected to the entire production line after being put into use, it is not easily disassembled and repaired. And most columnar bioreactors do not have a pre-breaking mechanism when discharging wastewater, resulting in the impurities inside the wastewater being extremely likely to block the subsequent discharge pipe during discharge, causing the columnar bioreactor to need to stop for maintenance, thereby reducing the working efficiency of the columnar bioreactor.

[0004] Therefore, the present invention provides a bioreactor for intelligently controlling algal growth. Summary of the Invention

[0005] In order to make up for the deficiencies of the prior art and solve at least one of the technical problems proposed in the background art.

[0006] The technical solution adopted by the present invention to solve its technical problems is as follows: An intelligent algae growth control bioreactor described in the present invention includes a support frame and a columnar reactor. The columnar reactor is installed on the support frame. A plurality of feed ports communicating with the inside are fixedly installed at the top of the columnar reactor. A controller for controlling the feed ports is installed on the surface of the columnar reactor. A partition is fixedly installed inside the columnar reactor, and a discharge port penetrating through itself is opened at the top of the partition. A crushing mechanism is arranged inside the columnar reactor. The crushing mechanism includes a cross beam fixedly installed below the partition. A protective frame is fixedly installed at the bottom of the cross beam. A servo motor is fixedly installed inside the protective frame. A connecting column is fixedly installed at the output end of the servo motor. A plurality of stagger-connected striking plates are fixedly installed on the surface of the connecting column.

[0007] Further, a flow guiding plate with a triangular cross-section is fixedly installed at the top of the cross beam, and the flow guiding plate is directly below the discharge port.

[0008] Further, an extension mechanism is arranged inside the striking plate. The extension mechanism includes a cavity opened inside the striking plate. An extension plate is slidably connected inside the cavity through a first spring. A sleeve plate is fixedly installed on the surface of the extension plate. A rubber ring is fixedly sleeved on the surface of the sleeve plate. A plurality of rotating balls are rotatably connected to one end of the extension plate away from the first spring.

[0009] Further, a flow guiding component is arranged inside the striking plate. The flow guiding component includes a storage cavity opened inside the connecting column. A plurality of hollow protrusions are fixedly installed inside the cavity of the striking plate. The plurality of protrusions are connected to the storage cavity through a flow guiding pipe with a one-way valve. A discharge pipe with a one-way valve and communicating with the protrusion is fixedly installed on one side of the striking plate. A feed pipe with a one-way valve is fixedly installed on the surface of the connecting column.

[0010] Further, an impact mechanism is arranged at the bottom of the striking plate. The impact mechanism includes a plurality of arc-shaped impact plates rotatably connected to the striking plate through torsion springs. A rotating column is rotatably connected to the bottom of the impact plate.

[0011] Further, a material suction mechanism is arranged at the output end of the servo motor. The material suction mechanism includes a fixing plate fixedly installed at the output end of the servo motor. A first electromagnet is fixedly installed at the top of the fixing plate.

[0012] A number of fixed cylinders are fixedly installed inside the columnar reactor. A number of the fixed cylinders are all above the partition plate. A sliding rod is slidably connected inside the fixed plate. The sliding rod passes through the partition plate. A second spring is fixedly installed between the sliding rod and the partition plate. A second electromagnet is fixedly installed at the bottom of the sliding rod. A sealing disc is fixedly installed at the top of the sliding rod. A number of through holes communicating with the inside are formed on the surface of the fixed cylinder.

[0013] Furthermore, a filter frame is fixedly installed inside the through hole.

[0014] Furthermore, a vibration mechanism is arranged inside the sliding rod. The vibration mechanism includes a number of rectangular grooves formed inside the sliding rod. A push plate is hermetically slidably connected inside the rectangular groove through a third spring. An impact ball is clamped inside the rectangular groove. The surface of the push plate is in contact with the impact ball.

[0015] Furthermore, the vibration mechanism further includes a telescopic assembly. The telescopic assembly includes a number of grooves formed inside the sliding rod. A sliding plate is hermetically slidably connected inside through an elastic rope. A number of dredging rods made of rubber are fixedly installed on the surface of the sliding plate. Two symmetrically arranged hollow elastic blocks are fixedly installed inside the rectangular groove. The surface of the impact ball is in contact with the elastic block. The elastic block and the groove are connected through a communicating pipe.

[0016] Furthermore, two symmetrically arranged guide plates are fixedly installed inside the through hole. One side of the guide plate is arc-shaped.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. For the biological reactor for intelligently controlling the growth of algae described in the present invention, by opening the discharge port inside the partition plate, the wastewater above the partition plate enters below the partition plate through the discharge port. At the same time, the servo motor inside the protection frame is started, and the connecting column and the striking plate are driven to rotate together by the servo motor. At this time, a number of staggeredly arranged striking plates will continuously impact and beat the wastewater, thereby breaking the granular impurities in the wastewater. And the staggeredly arranged striking plates can achieve a more efficient beating effect, effectively avoiding that after a number of striking plates are vertically arranged, the bottom striking plate is difficult to efficiently break the particles in the wastewater. Through the designed structure, the large granular impurities inside the wastewater are broken during the discharge of the wastewater. While not affecting the wastewater discharge efficiency, the filter screen can also be used to block the unqualified large granular impurities to prevent them from flowing away, thereby effectively preventing the subsequent equipment from being blocked by large granular impurities after long-term use, reducing equipment disassembly and maintenance while improving the working efficiency of the columnar reactor.

[0019] 2. A bioreactor for intelligently controlling the growth of algae according to the present invention. As the servo motor drives the connecting column to rotate faster and faster, the centrifugal force generated will cause the extension plate in the striking plate to slide away from the cavity. The extension plate drives the sleeve plate, the rotating ball and the first spring to move together. By extending the extension plate, it can adapt to columnar reactors with different diameters, so that the rotating ball fits against the inner wall of the columnar reactor, further crushing large particle impurities. When the extension plate moves, the elastic rotating ball plays a role in buffering and protecting the inner wall of the columnar reactor, preventing the end of the extension plate from directly hitting the inner wall of the columnar reactor and causing damage. At the same time, the rotating rotating ball can crush and remove the impurities adhering to the inner wall of the columnar reactor, thus realizing the function of cleaning the inner wall of the columnar reactor. At the same time, the rotating ball can reduce friction and facilitate the rotation of the extension plate. And when the extension plate drives the sleeve plate to move, it will squeeze the convex block, and the solvent is discharged through the discharge pipe, thereby assisting in decomposing the large particles in the wastewater in the columnar reactor. When the sleeve plate no longer squeezes the convex block, the solvent in the storage cavity replenishes the convex block through the diversion pipe. Since there will still be large particle impurities on the surface of the filter screen, when the striking plate at the bottom of the connecting column rotates, it will drive the arc-shaped impact plate and the rotating column to continuously knock on the surface of the filter screen, thereby assisting in crushing the large particle impurities remaining on the surface of the filter screen and effectively preventing the filter screen from being blocked.

[0020] 3. A bioreactor for intelligently controlling the growth of algae according to the present invention. When feeding nutrients, the servo motor in the protective frame is started, so that the output end of the servo motor drives the fixed plate and the first electromagnet to rotate at a constant speed. The second electromagnet drives the slide rod, the second spring and the sealing plate to move downward together, and part of the nutrients are sucked into the fixed cylinder and will flow out through the filter frame in the through hole. Through the designed structure, when feeding nutrients at the feed inlet, the nutrients above can be transferred to the lower part of the columnar reactor, so as to reasonably and evenly distribute the nutrients, effectively avoiding the situation that the nutrients are concentrated above the columnar reactor, resulting in slow growth of algae in the lower part.

[0021] When the impact ball moves to the through hole, it is no longer blocked and limited by the inner wall of the fixed cylinder. At this time, the third spring in the rectangular groove will drive the impact ball to move towards the through hole through the push plate, and then impact the filter frame. The filter frame vibrates, so that the nutrients stuck in the holes of the filter frame or the organisms adhered to the surface are shaken off. The gas in the elastic block quickly fills into the groove, so that the sliding plate in the groove drives the dredging rod to insert into a through hole above the impact ball and into the filter frame. The conical shape of the dredging rod can better insert into the holes of the filter frame, realizing the function of efficiently dredging the filter frame. And the dredging rod is made of elastic material and can deform, so when the slide rod moves up, the dredging rod will not get stuck in the holes of the filter frame, and thus does not affect the normal sliding of the slide rod.

[0042] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0043] like Figures 1 to 9 As shown, a bioreactor for intelligently controlling algae growth according to an embodiment of the present invention comprises a support frame 1 and a columnar reactor 2, wherein the columnar reactor 2 is mounted on the support frame 1, and a plurality of feed ports 4 communicating with the interior are fixedly mounted on the top of the columnar reactor 2, and a controller 3 for controlling the feed ports 4 is mounted on the surface of the columnar reactor 2, and a partition 5 is fixedly mounted inside the columnar reactor 2, and a discharge port 6 penetrating through the top of the partition 5 is provided. A crushing mechanism 10 is provided inside the columnar reactor 2, and the crushing mechanism 10 comprises a crossbeam 11 fixedly mounted below the partition 5, a protective frame 12 fixedly mounted at the bottom of the crossbeam 11, a servo motor 13 fixedly mounted inside the protective frame 12, a connecting column 14 fixedly mounted at the output end of the servo motor 13, and a plurality of staggered striking plates 15 fixedly mounted on the surface of the connecting column 14, a filter screen 16 fixedly mounted inside the columnar reactor 2, and a discharge port communicating with the interior is provided at the bottom of the columnar reactor 2. A guide plate 17 with a triangular cross section is fixedly mounted on the top of the crossbeam 11 , and the guide plate 17 is located directly below the discharge port 6 .

[0044] During operation, when using the column reactor 2 to cultivate algae, the controller 3 is used to control the feed port 4 at the top of the column reactor 2, and then the required nutrients are added according to the actual growth of the algae in the column reactor 2. At the same time, the controller 3 can also control the temperature and pH value in the column reactor 2. The above operations are all common knowledge in the art and will not be described in detail here. The above structure can realize intelligent control of algae growth. It should be noted that when using the column reactor 2 to cultivate algae, the algae grows above the partition 5. At this time, the space below the partition 5 is idle, and an electric control valve is provided in the discharge port 6 of the partition 5 for opening and closing.

[0045] When the columnar reactor 2 finishes growing and culturing the internal algae, by opening the discharge port 6 in the partition plate 5, the wastewater above the partition plate 5 enters below the partition plate 5 through the discharge port 6. At the same time, the servo motor 13 in the protective frame 12 is started, and the connecting column 14 and the striking plate 15 are driven to rotate together by the servo motor 13. When the wastewater flows down through the discharge port 6, it will be guided to both sides by the triangular guide plate 70. At this time, several staggeredly arranged striking plates 15 will continuously impact and beat the wastewater, thereby breaking the granular impurities in the wastewater. Moreover, the staggeredly arranged striking plates 15 can achieve a more efficient beating effect, effectively avoiding that after several striking plates 15 are vertically arranged, the bottom striking plate 15 is difficult to efficiently break the particles in the wastewater. At the same time, the installed filter screen 16 can block the unqualified particles to prevent them from flowing away with the wastewater.

[0046] Through the above-designed structure, the large particles of impurities inside the wastewater are broken during discharge. Without affecting the wastewater discharge efficiency, the filter screen 16 can also block the unqualified large particles of impurities to avoid their flowing away, thereby effectively preventing the subsequent equipment from being blocked by large particles of impurities after long-term use, reducing equipment disassembly and maintenance, and improving the working efficiency of the columnar reactor 2 at the same time.

[0047] An extension mechanism 20 is arranged inside the striking plate 15. The extension mechanism 20 includes a cavity 21 opened in the striking plate 15. An extension plate 22 is slidably connected in the cavity 21 through a first spring 23. A sleeve plate 24 is fixedly installed on the surface of the extension plate 22. A rubber ring is fixedly sleeved on the surface of the sleeve plate 24. Several rotating balls 25 are rotatably connected to one end of the extension plate 22 away from the first spring 23.

[0048] Specifically, a diversion assembly 26 is arranged inside the striking plate 15. The diversion assembly 26 includes a storage cavity 261 opened in the connecting column 14. Several hollow bumps 263 are fixedly installed in the cavity 21 of the striking plate 15. The several bumps 263 are connected to the storage cavity 261 through a diversion pipe 262 with a one-way valve. A discharge pipe 264 with a one-way valve and connected to the bumps 263 is fixedly installed on one side of the striking plate 15. A feed pipe with a one-way valve is fixedly installed on the surface of the connecting column 14. An impact mechanism 30 is arranged at the bottom of the striking plate 15. The impact mechanism 30 includes several arc-shaped impact plates 31 rotatably connected to the striking plate 15 through torsion springs. A rotating column 32 is rotatably connected to the bottom of the impact plate 31.

[0049] During operation, when the servo motor 13 drives the striking plate 15 to rotate through the connecting column 14, as the rotation speed of the servo motor 13 driving the connecting column 14 increases, the centrifugal force generated will slide the extension plate 22 in the striking plate 15 away from the cavity 21. The extension plate 22 drives the sleeve plate 24, the rotating ball 25 and the first spring 23 to move together. By extending the extension plate 22, it can adapt to columnar reactors 2 with different diameters, so that the rotating ball 25 fits against the inner wall of the columnar reactor 2, further breaking up large particle impurities. When the extension plate 22 moves, the elastic rotating ball 25 plays a role in buffering and protecting the inner wall of the columnar reactor 2, preventing the end of the extension plate 22 from directly hitting the inner wall of the columnar reactor 2 and causing damage. At the same time, the rotating rotating ball 25 can crush and remove the impurities adhering to the inner wall of the columnar reactor 2, thus achieving the effect of cleaning the inner wall of the columnar reactor 2. At the same time, the rotating ball 25 can reduce friction and facilitate the rotation of the extension plate 22. And when the extension plate 22 drives the sleeve plate 24 to move, it will squeeze the solvent (which can be cellulase, hemicellulase, lipase, selected according to the actual situation) in the bump 263 (made of elastic material). The solvent is discharged through the discharge pipe 264, thereby assisting in the decomposition of large particles in the wastewater in the columnar reactor 2. When the sleeve plate 24 no longer squeezes the bump 263, the solvent in the storage cavity 261 replenishes the solvent in the bump 263 through the diversion pipe 262. It should be noted that one-way valves are installed in the diversion pipe 262, the discharge pipe 264 and the feed pipe, so they can only flow in one direction.

[0050] Since there will still be large particle impurities on the surface of the filter screen 16, when the striking plate 15 at the bottom of the connecting column 14 rotates, it will drive the arc-shaped impact plate 31 and the rotating column 32 to continuously knock on the surface of the filter screen 16, thereby assisting in breaking up the large particle impurities remaining on the surface of the filter screen 16 and effectively preventing the filter screen 16 from being blocked.

[0051] A material suction mechanism 40 is provided on the output end of the servo motor 13. The material suction mechanism 40 includes a fixing plate 41 fixedly installed on the output end of the servo motor 13. A first electromagnet 42 is fixedly installed on the top of the fixing plate 41. A number of fixing cylinders 43 are fixedly installed in the columnar reactor 2. All the fixing cylinders 43 are above the partition plate 5. A sliding rod 44 is slidably connected in the fixing plate 41. The sliding rod 44 passes through the partition plate 5. A second spring 46 is fixedly installed between the sliding rod 44 and the partition plate 5. A second electromagnet 45 is fixedly installed at the bottom of the sliding rod 44. A sealing disk 47 is fixedly installed at the top of the sliding rod 44. A number of through holes 48 communicating with the inside are formed on the surface of the fixing cylinder 43. A filter frame 50 is fixedly installed in the through hole 48.

[0052] Specifically, a vibration mechanism 60 is provided inside the sliding rod 44. The vibration mechanism 60 includes a number of rectangular grooves 61 formed inside the sliding rod 44. Inside the rectangular groove 61, a push plate 62 is hermetically and slidably connected through a third spring 63. An impact ball 64 is wedged inside the rectangular groove 61, and the surface of the push plate 62 is in contact with the impact ball 64. The vibration mechanism 60 further includes a telescopic assembly 65. The telescopic assembly 65 includes a number of grooves 651 formed inside the sliding rod 44. Inside, a sliding plate is hermetically and slidably connected through an elastic cord 653. A number of dredging rods 652 made of rubber are fixedly installed on the surface of the sliding plate. Two symmetrically arranged hollow elastic blocks 654 are fixedly installed inside the rectangular groove 61. The surface of the impact ball 64 is in contact with the elastic blocks 654. The elastic blocks 654 and the grooves 651 are connected through a communicating pipe 655. Two symmetrically arranged guide plates 70 are fixedly installed inside the through hole 48, and one side of the guide plate 70 is arc-shaped.

[0053] During operation, when the columnar reactor 2 is culturing algae for growth (note that there is no wastewater discharge operation at this time), when nutrients are put into the columnar reactor 2 through the feed inlet 4, since the feed inlet 4 of the columnar reactor 2 is mostly designed in a certain position, and the columnar reactor 2 has a certain depth, it is difficult for the algae near the lower part of the columnar reactor 2 to absorb nutrients, while the algae near the feed inlet 4 absorb too much nutrients, which easily leads to the phenomenon that the growth conditions of the algae in the same columnar reactor 2 are different.

[0054] When nutrients are put in, the servo motor 13 inside the protective frame 12 is started, so that the output end of the servo motor 13 drives the fixing plate 41 and the first electromagnet 42 to rotate at a constant speed (it should be noted that the rotation speed is not very fast at this time), and both the first electromagnet 42 and the second electromagnet 45 are energized. When the fixing plate 41 drives the first electromagnet 42 to move to the position of the second electromagnet 45, the second electromagnet 45 will be attracted by the opposite sex of the first electromagnet 42, and then drive the sliding rod 44, the second spring 46 and the sealing disc 47 to move downward together. Since the top of the fixed cylinder 43 is close to the feed inlet 4, when the sealing disc 47 moves downward, it will suck in some nutrients into the fixed cylinder 43. As the sealing disc 47 and the sliding rod 44 continue to move downward, some nutrients will flow out through the filter frame 50 inside the through hole 48. As the first electromagnet 42 continues to rotate, the first electromagnet 42 and the second electromagnet 45 are separated, and the sliding rod 44 and the sealing disc 47 slide upward and reset under the action of the second spring 46, and then squeeze and push out the remaining nutrients in the fixed cylinder 43 through the through hole 48 again, so as to reduce the nutrients remaining in the fixed cylinder 43.

[0055] Through the above-designed structure, when the feed inlet 4 puts in nutrients, the nutrients above can be transferred to the lower part of the columnar reactor 2, so as to reasonably and evenly distribute the nutrients, effectively avoiding the situation that the nutrients are concentrated above the columnar reactor 2, resulting in slow growth of the algae below.

[0056] It should be noted that when discharging the wastewater in the columnar reactor 2 through the discharge port 6, neither the first electromagnet 42 nor the second electromagnet 45 is energized, so they will not attract each other.

[0057] When the sliding rod 44 slides upward to reset, the impact ball 64 and the dredging rod 652 will move together. When the impact ball 64 moves to the through hole 48, it is no longer blocked and limited by the inner wall of the fixed cylinder 43. At this time, the third spring 63 in the rectangular groove 61 will drive the impact ball 64 towards the through hole 48 through the push plate 62, and then impact the filter frame 50, causing the filter frame 50 to vibrate, so that the nutrients stuck in the holes of the filter frame 50 or the organisms adhering to the surface are shaken off. When the impact ball 64 moves towards the filter frame 50, it will squeeze the elastic block 654 in the rectangular groove 61. At this time, the gas in the elastic block 654 quickly fills into the groove 651, causing the sliding plate in the groove 651 to drive the dredging rod 652 to insert into a through hole 48 above the impact ball 64 and into the filter frame 50. The conical shape of the dredging rod 652 can better insert into the holes of the filter frame 50 to achieve the effect of efficiently dredging the filter frame 50. Moreover, the dredging rod 652 is made of elastic material and can deform, so when the sliding rod 44 moves upward, the dredging rod 652 will not get stuck in the holes of the filter frame 50, thus not affecting the normal sliding of the sliding rod 44. As the sliding rod 44 continues to slide upward, the impact ball 64 slides and contracts into the rectangular groove 61 with the assistance of the guide plate 70, and then no longer squeezes the elastic block 654. The elastic block 654 will expand and reset under its own elastic force and suck part of the gas in the groove 651, causing the sliding plate and the dredging rod 652 to slide and reset into the groove 651, thereby reducing the influence on the movement of the sliding rod 44.

[0058] Working principle: When using the columnar reactor 2 to cultivate algae, the controller 3 is used to control the feeding port 4 at the top of the columnar reactor 2, so as to put in the required nutrients according to the actual growth situation of the algae in the columnar reactor 2. At the same time, the controller 3 can also control the temperature and pH value in the columnar reactor 2. Through the above structure, the intelligent control of the growth of algae can be realized. When the columnar reactor 2 completes the growth and cultivation of the internal algae, by opening the discharge port 6 in the partition plate 5, the wastewater above the partition plate 5 enters below the partition plate 5 through the discharge port 6. At the same time, the servo motor 13 in the protection frame 12 is started, and the servo motor 13 drives the connecting column 14 and the striking plate 15 to rotate together. When the wastewater flows down through the discharge port 6, it will be guided to both sides by the triangular guide plate 70. At this time, several staggeredly arranged striking plates 15 will continuously impact and beat the wastewater, thereby breaking the particulate impurities in the wastewater. It is difficult for the bottom striking plate 15 to efficiently break the particles in the wastewater.

[0059] When the servo motor 13 drives the striking plate 15 to rotate through the connecting column 14, as the rotation speed of the servo motor 13 driving the connecting column 14 becomes faster and faster, the centrifugal force generated will slide the extension plate 22 in the striking plate 15 away from the cavity 21. The extension plate 22 drives the sleeve plate 24, the rotating ball 25 and the first spring 23 to move together. And when the extension plate 22 drives the sleeve plate 24 to move, it will squeeze the solvent in the bump 263, and the solvent is discharged through the discharge pipe 264. When the sleeve plate 24 no longer squeezes the bump 263, the solvent in the storage cavity 261 replenishes the solvent in the bump 263 through the diversion pipe 262. Since there will still be large particle impurities on the surface of the filter screen 16, when the striking plate 15 at the bottom of the connecting column 14 rotates, it will drive the arc-shaped impact plate 31 and the rotating column 32 to continuously knock on the surface of the filter screen 16, thereby assisting in breaking the large particle impurities remaining on the surface of the filter screen 16.

[0060] When feeding the nutrient, the servo motor 13 in the protective frame 12 is started, so that the output end of the servo motor 13 drives the fixing plate 41 and the first electromagnet 42 to rotate at a constant speed, and both the first electromagnet 42 and the second electromagnet 45 are energized. When the fixing plate 41 drives the first electromagnet 42 to move to the second electromagnet 45, the second electromagnet 45 will be attracted by the opposite polarity of the first electromagnet 42, and then drive the slide rod 44, the second spring 46 and the sealing disc 47 to move downward together. Since the top of the fixed cylinder 43 is close to the feed inlet 4, when the sealing disc 47 moves downward, it will suck in part of the nutrient into the fixed cylinder 43. As the sealing disc 47 and the slide rod 44 continue to move downward, part of the nutrient will flow out through the filter frame 50 in the through hole 48. As the first electromagnet 42 continues to rotate, the first electromagnet 42 and the second electromagnet 45 separate, and the slide rod 44 and the sealing disc 47 slide upward and reset under the action of the second spring 46, and then squeeze and push out the remaining nutrient in the fixed cylinder 43 through the through hole 48 again, so as to reduce the nutrient remaining in the fixed cylinder 43.

[0061] When the sliding rod 44 slides upward to reset, the impact ball 64 and the dredging rod 652 will move together. When the impact ball 64 moves to the through hole 48, it is no longer blocked and limited by the inner wall of the fixed cylinder 43. At this time, the third spring 63 in the rectangular groove 61 will drive the impact ball 64 towards the through hole 48 through the push plate 62, and then impact the filter frame 50, causing the filter frame 50 to vibrate, so that the nutrients stuck in the holes of the filter frame 50 or the organisms adhered to the surface are shaken off. When the impact ball 64 moves towards the filter frame 50, it will squeeze the elastic block 654 in the rectangular groove 61. At this time, the gas in the elastic block 654 quickly fills into the groove 651, so that the sliding plate in the groove 651 drives the dredging rod 652 to insert into a through hole 48 above the impact ball 64 and into the filter frame 50. As the sliding rod 44 continues to slide upward, the impact ball 64 slides and contracts into the rectangular groove 61 with the assistance of the guiding plate 70, and then no longer squeezes the elastic block 654. The elastic block 654 will expand and reset under its own elastic action and suck part of the gas in the groove 651, so that the sliding plate and the dredging rod 652 slide and reset into the groove 651.
