Description

Technical Field

[0001] This invention relates to the field of aquaculture technology, and in particular to an integrated recirculating aquaculture system for aquaculture. Background Technology

[0002] With population growth and increasing demand for aquatic products, coupled with limitations in land and water resources, traditional aquaculture methods can no longer meet the growing demand. In order to improve the efficiency and production capacity of aquaculture, factory-style recirculating aquaculture systems have emerged. Currently, there are many recirculating aquaculture systems both domestically and internationally, but these systems are characterized by high energy consumption and high cost.

[0003] In aquaculture water, microorganisms and bacteria consume oxygen and produce carbon dioxide through respiration. Fish and other aquatic animals breathe dissolved oxygen in the water through their gills, while simultaneously expelling their own carbon dioxide into the water outside their bodies, resulting in high carbon dioxide levels in the aquaculture water. Existing technologies often use carbon removal towers to remove excess carbon dioxide from aquaculture water. This mainly utilizes a blower deaeration method, where water is passed through a packing layer, and air is blown into the tower by a blower, making counter-current contact with the water and thus carrying away the carbon dioxide inside the water in the packing layer. Whether the water enters the packing layer evenly is a crucial factor affecting the carbon removal effect. Existing technologies include a distributor in which multiple pipes with the same top surface height are inserted into the surface of a water-blocking plate. Ideally, when the liquid level is slightly higher than the top surface of the pipes, the water enters relatively evenly from the top surfaces of the multiple pipes. In reality, due to possible errors in the height of the pipe top surfaces and the continuous flow of water, it is difficult to achieve the ideal situation where water enters evenly from each pipe. This affects the even distribution of water when it falls into the packing layer, thus impacting the effectiveness of carbon dioxide removal from the aquaculture water. Summary of the Invention

[0004] The purpose of this invention is to provide an integrated circulating water biological tower device for aquaculture, which enables water to enter each pipe more evenly, thereby improving the uniformity of water falling into the filling layer.

Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1 to 6 This invention provides a technical solution: an integrated recirculating aquaculture system (RAS) bio-tower device, comprising a bottom tank 1, a top tank 2 detachably connected to the top of the bottom tank 1, a water-feeding assembly 3 for adding aquaculture water to the top of the top tank 2, a distribution assembly 4 on the inner top of the top of the top tank 2, the distribution assembly 4 including a water-blocking plate 41 fixedly connected to the inner top of the top of the top tank 2, pipes 42 fixedly inserted into a circular array on the surface of the water-blocking plate 41, a buoyancy block 43 at the top center of the water-blocking plate 41, an inlet groove 44 opened on the circumferential side of the pipes 42 near the buoyancy block 43, a small block 45 fixedly connected to the inner center of the inlet groove 44, a moving rod 46 slidably connected to the center of the small block 45, a blocking plate 47 fixedly connected to the end of the moving rod 46 away from the buoyancy block 43, and the interior of the pipes 42 located opposite the inlet groove 44. A horn tube 48 is fixedly connected to the position. The horn tube 48 is inclined on the side away from the inlet 44. The circumferential side of the blocking plate 47 is inclined. The top of the buoyancy block 43 is inclined. An L-shaped frame 49 is fixedly connected to the side of the moving rod 46 near the buoyancy block 43. A ring 410 is fixedly connected to the outer wall of the moving rod 46 inside the horn tube 48. A U-shaped spring piece 411 is fixedly connected between the ring 410 and the small block 45. Limiting plates 10 are fixedly connected to the top two sides of the water blocking plate 41 at the corresponding positions on the circumferential side of the buoyancy block 43. A tray 8 is set inside the top tank 2 below the discharge rack 75. A circular plate 11 is fixedly connected inside the bottom tank 1. A sealing gasket can be glued to the circumferential side of the blocking plate 47 to ensure sealing. The water blocking plate 41 is spliced ​​from two semi-circular plates, which facilitates the installation of the gas pressure sensor 63 and the opening of the transition groove 64.

[0032] By adopting the above technical solution, two trays 8 are provided. An air inlet pipe is fixedly inserted into the circumference of the bottom tank 1 for air to enter. The upper tray 8 is filled with multi-faceted hollow spherical packing, and the lower tray 8 is filled with honeycomb decarbonization material. The multi-faceted hollow spherical packing ensures that the water falling from the distribution component 4 falls more evenly on the honeycomb decarbonization material. The honeycomb decarbonization material is porous, and the contact area between the water and the air entering through the air inlet pipe is large, thereby improving the effect of removing carbon dioxide from the aquaculture water. The bottom tank 1 and the top tank 2 can be detachably connected by a flange connection. The gas enters from the air inlet pipe, carries out carbon dioxide, enters above the water baffle plate 41 through the pipe 42, and is discharged from the top opening of the top tank 2.

[0033] Styrene foam filter beads are installed above the circular plate 11. These beads have a large specific surface area and can attach more microorganisms to treat ammonia nitrogen and nitrite in the water, thereby improving the treatment effect. The device integrates the functions of carbon removal and ammonia nitrogen and nitrite removal.

[0034] This device is used to treat wastewater from recirculating aquaculture. After the wastewater is discharged, it first passes through a series of devices such as a microfiltration machine to remove impurities. Then, the wastewater is placed into the interior of the top tank 2 from the water drop assembly 3 on the top tank 2. The water inside the top tank 2 falls and accumulates above the water baffle 41. As the water to be treated is continuously added, the water level above the water baffle 41 gradually increases, causing the buoyancy block 43 to move upward under the action of buoyancy. When the inclined top surface of the buoyancy block 43 moves close to the multiple L-shaped frames 49 and squeezes the L-shaped frames 49, the L-shaped frames 49 move away from the buoyancy block 43 along with the moving rod 46. At this time, the ring 410 also moves away from the buoyancy block 43, causing the U-shaped spring 41 to... 1. Slight deformation. During this process, the moving rod 46 moves with the blocking plate 47, and a certain gap is created between the blocking plate 47 and the horn tube 48. During this process, the water above the water blocking plate 41 flows into the horn tube 48 in the pipe 42 through the inlet 44 and flows out from the gap between the horn tube 48 and the blocking plate 47. This design ensures that each time water is placed into the upper tray 8, the liquid level is always higher than the inlet 44 on the pipe 42, so that the water can enter each pipe 42 more evenly, thereby improving the uniformity of water falling into the filling layer. This facilitates the even and sufficient contact between the introduced air and water, thereby improving the effect of removing carbon dioxide from the aquaculture water. The design of the small piece 45 makes the moving rod 46 move horizontally.

[0035] It should be noted that in practical applications, the volume of the buoyancy block 43 is set to be relatively large, so that the volume of water displaced when it floats is relatively large, and the buoyancy is also relatively large. The buoyancy generated by the buoyancy block 43 is greater than the sum of the elastic forces of multiple U-shaped springs 411, and the buoyancy block 43 is sufficient to push open multiple L-shaped frames 49 when it rises.

[0036] It should be noted that the limiting plate 10 is an arc-shaped plate with an internal curvature that matches the buoyancy block 43. The limiting plate 10 is used to limit the buoyancy block 43 and ensure that it moves in the vertical direction. The inner side of the limiting plate 10 is rotatably connected with ball bearings to reduce the friction of the buoyancy block 43 moving up and down.

[0037] When the liquid level is low, the buoyancy block 43 does not compress the L-shaped frame 49. At this time, under the elastic force of the U-shaped spring sheet 411 itself, the circumferential side of the blocking plate 47 blocks the horn tube 48. It should be noted that the elastic force of the U-shaped spring sheet 411 is greater than the pressure exerted by the water on the blocking plate 47.

[0038] Specifically, such as Figures 2 to 8 As shown, a stopping component 5 is provided inside and on the top of the water-blocking plate 41. The stopping component 5 includes a fixing frame 51 fixedly connected to the middle part of the top of the water-blocking plate 41. A through groove 52 is opened inside the left side of the fixing frame 51. A first elastic membrane 53 is fixedly connected to the left side of the through groove 52. A limit rod 54 is fixedly connected to the middle part of the first elastic membrane 53. The right side of the limit rod 54 is slidably connected to the fixing frame 51. A groove 55 is opened inside the left side of the buoyancy block 43. A locking hole 56 is opened inside the buoyancy block 43 near the groove 55. A trigger component 6 is provided on the left side and the left side of the water-blocking plate 41. The trigger component 6 includes a circular hole 61 opened at the upper end of the water-blocking plate 41 below the buoyancy block 43. A second elastic membrane 62 is fixedly connected to the top of the inner wall of the circular hole 61. A gas pressure sensor 63 is fixedly connected to the left side of the circular hole 61 inside the water-blocking plate 41. The gas pressure sensor 63 is a mature existing technology and will not be described in detail. The detection end of the gas pressure sensor 63 is inserted into the interior of the circular hole 61. The triggering component 6 also includes a transition groove 64 opened inside the water-blocking plate 41 below the circular hole 61. The triggering component 6 also includes a hollow groove 65 opened inside the water-blocking plate 41 near the inner wall of the top tank 2. The triggering component 6 also includes an electric telescopic rod 66 fixedly connected to the left side of the top tank 2. The output shaft of the electric telescopic rod 66 passes through the top tank 2 and extends into the hollow groove 65, where a piston plate 67 is fixedly connected. The outer side of the piston plate 67 is in contact with the inner wall of the hollow groove 65. The hollow groove 65 communicates with the transition groove 64 and the through groove 52. A ball bearing is rotatably connected to the left side of the limiting rod 54.

[0039] By adopting the above technical solution, when the liquid level rises, the buoyancy block 43 rises. During this process, due to the large pressure exerted by the liquid on the second elastic membrane 62 above the circular hole 61, the second elastic membrane 62 undergoes a slight deformation. Thus, the gas pressure sensor 63 detects the change in pressure inside the circular hole 61 and transmits the signal to the external control system, controlling the output shaft of the electric telescopic rod 66 to extend, causing the piston plate 67 to move to the right. At this time, since the empty groove 65 is connected to the transition groove 64, the air inside the empty groove 65 enters the interior of the transition groove 64, and since the transition groove 64 is connected to the through groove 52... This allows gas to enter the interior of the channel 52. Under the pressure of the gas, the first elastic membrane 53 deforms, and the limiting rod 54 moves to the right. When the top surface of the buoyancy block 43 moves to a position close to the multiple L-shaped frames 49, the left side of the limiting rod 54 contacts the left inner wall of the groove 55. When the top surface of the buoyancy block 43 presses against the L-shaped frame 49, the left side of the limiting rod 54 just fits into the hole 56, thus limiting the buoyancy block 43. This allows the blocking plate 47 to remain unblocked from the horn tube 48 for a period of time, so that all the liquid above the water-blocking plate 41 can be discharged.

[0040] This design avoids the buoyancy block 43 immediately moving downwards after the water level drops from pipe 42, causing the circumferential side of the blocking plate 47 to block the horn tube 48. This ensures that more water is discharged each time, and this water is discharged more evenly from multiple pipes 42, thereby further improving the uniformity of water falling. This facilitates the even and sufficient contact between the introduced air and water, thereby improving the effect of removing carbon dioxide from the aquaculture water.

[0041] When all the liquid above the water-blocking plate 41 is discharged, there is no water to exert pressure on the second elastic membrane 62, and the second elastic membrane 62 returns to its initial state. At this time, the gas pressure sensor 63 detects the change in pressure inside the circular hole 61 and sends a command through the control system to retract the output shaft of the electric telescopic rod 66. In this way, the gas in the through groove 52 returns to the empty groove 65, the first elastic membrane 53 returns to its initial state, and the limiting rod 54 moves to the right. The left part of the limiting rod 54 leaves the inside of the locking hole 56. Under the action of the gravity of the buoyancy block 43, the buoyancy block 43 descends. At this time, the blocking plate 47 blocks the horn tube 48.

[0042] Specifically, such as Figures 1 to 4 As shown, the water-falling assembly 3 includes an inlet pipe 31 rotatably connected to the top of the top tank 2. A connecting frame 32 is fixedly connected to the inner wall of the inlet pipe 31. A guide cover 33 is fixedly connected to the bottom of the connecting frame 32. The circumferential side of the guide cover 33 is close to the inner wall of the top tank 2. A rotary joint 34 is installed on the top of the inlet pipe 31. A driving component 12 for driving the inlet pipe 31 to rotate is provided on the top of the top tank 2.

[0043] By adopting the above technical solution, the drive component 12 can use a motor and gears to drive the inlet pipe 31 to rotate. This technology is a mature existing technology, so it will not be described in detail. The rotary joint 34 is also a mature existing technology, and its principle and installation method will not be described in detail.

[0044] Water treated by the microfilter enters the rotary joint 34 and then flows through the inlet pipe 31 to the top surface of the guide cover 33. There is a movable gap between the circumferential side of the guide cover 33 and the interior of the top tank 2. As the inlet pipe 31 rotates, carrying the guide cover 33, the incoming water flows down the inner wall of the top tank 2 in a liquid film state. This reduces the impact of the falling water on the water above the baffle plate 41, making the water above the baffle plate 41 more stable. This reduces liquid fluctuations on the baffle plate 41 that could affect the rising state of the buoyancy block 43, thereby minimizing disruptions to the uniform flow of water.

[0045] Specifically, such as Figures 2 to 3 As shown, a sponge pad 9 is fixedly connected to the top ring side of the water-blocking plate 41, and the top of the guide cover 33 is inclined.

[0046] By adopting the above technical solution, the design of the sponge pad 9 plays a role in buffering the falling water, further making the water above the water-blocking plate 41 more calm.

[0047] Specifically, such as Figures 2 to 6 As shown, a dispersion component 7 is provided below the inlet pipe 31. The dispersion component 7 includes a reciprocating screw 71 fixedly connected to the bottom of the guide cover 33. A screw sleeve 72 is threadedly connected to the bottom surface of the reciprocating screw 71. A lifting rod 73 is fixedly connected to the bottom of the screw sleeve 72. Connecting plates 74 are fixedly connected to the bottom of the ring side of the lifting rod 73 in a ring array. The outer wall of the lifting rod 73 is slidably connected to the fixing frame 51. The dispersion component 7 also includes a discharge frame 75 slidably connected to the bottom of the pipe 42. A sleeve 76 is slidably connected to both sides of the top of the discharge frame 75. A threaded rod 77 is threadedly connected to the bottom of the inner end of the sleeve 76. A dispersing plate 78 is fixedly connected to the bottom of the ring side of the threaded rod 77. A small plate 79 is fixedly connected to the inner wall of the discharge frame 75. The bottom of the outer wall of the threaded rod 77 is rotatably connected to the small plate 79. The side of the multiple connecting plates 74 near the discharge frame 75 is fixedly connected to the discharge frame 75.

[0048] By adopting the above technical solution, when the inlet pipe 31 rotates with the connecting frame 32 and the guide cover 33, the reciprocating screw 71 can rotate, which allows the screw sleeve 72 to move up and down with the lifting rod 73, thereby causing the connecting plate 74 to move up and down with the discharge frame 75. At this time, the small plate 79 moves up and down with the threaded rod 77. During this process, relative movement occurs between the threaded rod 77 and the sleeve 76. Under the action of the threaded connection, the threaded rod 77 rotates with the dispersing plate 78 to disperse the falling water, further improving the uniformity of water falling, which is conducive to the uniform and sufficient contact between the introduced air and water, thereby improving the effect of removing carbon dioxide from the aquaculture water.

[0049] It should be noted that the thread pitch at the top of the threaded rod 77 is relatively large, which helps to reduce the resistance of movement, so that when there is relative movement between the threaded rod 77 and the sleeve 76, the threaded rod 77 can rotate smoothly. The thread of the threaded rod 77 and the way it is threadedly connected to the sleeve 76 are similar to the screw part and the flying saucer part of a hand-pushed flying saucer.

[0050] Working principle: Gas enters through the air inlet pipe, carrying carbon dioxide, and then enters above the water baffle plate 41 through pipe 42, and is discharged from the top opening of the top tank 2. Wastewater enters the top tank 2 through the water drop assembly 3 on the top tank 2. The water entering the top tank 2 falls and accumulates above the water baffle plate 41. As the water to be treated is continuously added, the water level above the water baffle plate 41 gradually increases, causing the buoyancy block 43 to move upward under the action of buoyancy. When the inclined top surface of the buoyancy block 43 moves close to the multiple L-shaped frames 49 and squeezes the L-shaped frames 49, the L-shaped frames 49, along with the moving rod 46, move away from the buoyancy block. As the buoyancy block 43 moves, the ring 410 moves away from the buoyancy block 43, causing the U-shaped spring 411 to deform slightly. During this process, the moving rod 46 moves the blocking plate 47, creating a gap between the blocking plate 47 and the horn tube 48. Water above the water-blocking plate 41 flows through the inlet 44 into the horn tube 48 inside the pipe 42 and out through the gap between the horn tube 48 and the blocking plate 47. This design ensures that each time water is placed into the upper tray 8, the liquid level is always higher than the inlet 44 on the pipe 42, allowing water to enter each pipe 42 more evenly. To improve the uniformity of water falling into the filling layer, the buoyancy block 43 rises as the liquid level rises. During this process, the liquid surface exerts a large pressure on the second elastic membrane 62 above the circular hole 61, causing a slight deformation of the second elastic membrane 62. This allows the gas pressure sensor 63 to detect the pressure change inside the circular hole 61 and transmit the signal to the external control system, which then controls the output shaft of the electric telescopic rod 66 to extend, causing the piston plate 67 to move to the right. At this time, because the empty groove 65 is connected to the transition groove 64, air inside the empty groove 65 enters the interior of the transition groove 64, and because the transition groove 64 is connected to the through groove 52... The connection allows gas to enter the interior of the channel 52. Under the pressure of the gas, the first elastic membrane 53 deforms, and the limiting rod 54 moves to the right. When the top surface of the buoyancy block 43 moves to a position close to the multiple L-shaped frames 49, the left side of the limiting rod 54 contacts the left inner wall of the groove 55. When the top surface of the buoyancy block 43 presses against the L-shaped frame 49, the left side of the limiting rod 54 just fits into the hole 56, thus limiting the buoyancy block 43. This allows the blocking plate 47 to remain unblocked from the horn tube 48 for a period of time, so that all the liquid above the water-blocking plate 41 can be discharged.

[0051] When the inlet pipe 31 rotates along with the connecting frame 32 and the guide cover 33, the reciprocating screw 71 rotates, causing the screw sleeve 72 to move up and down along with the lifting rod 73. This, in turn, causes the connecting plate 74 to move up and down along with the discharge frame 75. At this time, the small plate 79 moves up and down along with the threaded rod 77. During this process, relative motion occurs between the threaded rod 77 and the sleeve 76. Under the action of the threaded connection, the threaded rod 77 rotates along with the dispersing plate 78 to disperse the falling water, further improving the uniformity of water falling and facilitating the even and sufficient contact between the introduced air and water, thereby improving the effect of removing carbon dioxide from the aquaculture water.
