Description

Technical Field

[0001] The invention relates to the technical field of aquaculture, in particular to a circulating water biological tower integrated equipment for aquaculture. Background Art

[0002] With the growth of population and the continuous increase in demand for aquatic products, and at the same time due to the limitations of land and water resources, traditional breeding methods can no longer meet the growing demand. In order to improve the efficiency and production capacity of aquaculture, factory-based recirculating aquaculture equipment has come into being. At present, there are many recirculating aquaculture systems at home and abroad, but the equipment of these recirculating aquaculture systems has the characteristics of high energy consumption and high cost.

[0003] In aquaculture water, microorganisms and bacteria consume oxygen and produce carbon dioxide through respiration, and fish and other aquatic animals breathe oxygen dissolved in water through gills, and discharge the carbon dioxide produced by themselves into the water outside the body, resulting in a high carbon dioxide content in aquaculture water. In the prior art, a carbon removal tower is often used to remove excess carbon dioxide in part of the aquaculture water. The method of air blast degassing is mainly used to pass water into the packing layer, and air is blown into the tower through a fan to contact with the water in reverse, thereby taking away the carbon dioxide inside the water in the packing layer. Whether the water enters the packing layer evenly is an important factor affecting the carbon removal effect. In the prior art, there is a distributor, in which multiple pipes with the same top surface height are plugged on the surface of the water blocking plate. Under ideal conditions, when the liquid level is slightly higher than the top surface of the pipe, water enters more evenly from the top surfaces of multiple pipes. Under actual conditions, since there may be errors in the height of the top surface of the pipe and the water is constantly flowing, it is difficult for each pipe to enter the water evenly as in the ideal state, thereby affecting the uniform distribution of water when it falls on the packing layer, thereby affecting the effect of removing carbon dioxide from the aquaculture water.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figures 1 to 6 The present invention provides a technical solution: a circulating water biological tower integrated equipment for aquaculture, comprising a bottom tank 1, the top of the bottom tank 1 is detachably connected to a top tank 2, the top of the top tank 2 is provided with a water drop assembly 3 for adding aquaculture water into the top tank 2, the inner top of the top tank 2 is provided with a distribution assembly 4, the distribution assembly 4 comprises a water blocking plate 41 fixedly connected to the inner top of the top tank 2, a pipe 42 is fixedly plugged into the surface annular array of the water blocking plate 41, a buoyancy block 43 is provided at the middle position of the top of the water blocking plate 41, an inlet groove 44 is provided at the position of the annular side of the pipe 42 near the buoyancy block 43, a small block 45 is fixedly connected to the inner middle part of the inlet groove 44, a moving rod 46 is slidably connected to the middle part of the small block 45, and a blocking plate 47 is fixedly connected to the end of the moving rod 46 away from the buoyancy block 43, and the interior of the pipe 42 is located opposite to the inlet groove 44 A trumpet tube 48 is fixedly connected to the corresponding position, and the trumpet tube 48 is inclined on the side away from the inlet groove 44, the ring side of the blocking plate 47 is inclined, and the top of the buoyancy block 43 is inclined. The moving rod 46 is fixedly connected to an L-shaped frame 49 on the side close to the buoyancy block 43, and the outer wall of the moving rod 46 is located inside the trumpet tube 48 and is fixedly connected to a circular ring 410, and a U-shaped spring piece 411 is fixedly connected between the circular ring 410 and the small block 45. The top two sides of the water blocking plate 41 are located at the corresponding positions of the ring side of the buoyancy block 43 and are fixedly connected to limit plates 10. The interior of the top tank 2 is located below the discharge frame 75 and a tray 8 is provided. The interior of the bottom tank 1 is fixedly connected to a circular plate 11. A sealing gasket can be bonded to the ring side of the blocking plate 47 to ensure sealing. The water blocking plate 41 is composed of two semicircular plates spliced ​​together to facilitate the installation of the gas pressure sensor 63 and the opening of the transition groove 64.

[0032] By adopting the above technical scheme, two trays 8 are provided, and an air inlet pipe is fixedly inserted on the ring side of the bottom tank 1 for introducing air. A multi-faceted hollow ball filler is provided inside the upper tray 8, and a honeycomb decarbonization material is provided inside the lower tray 8. The multi-faceted hollow ball filler allows the water falling from the distribution component 4 to fall 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 larger after the water enters, thereby improving the effect of removing carbon dioxide from the aquaculture water. The detachable connection between the bottom tank 1 and the top tank 2 can be a flange connection. The gas enters from the air inlet pipe, brings out the carbon dioxide, and enters the top of the water blocking plate 41 from the pipe 42, and is discharged from the top opening of the top tank 2.

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

[0034] The device is used to treat sewage during circulating aquaculture. After the aquaculture sewage is discharged, it is firstly removed from the impurities in the water by a series of equipment such as a microfilter, and then the sewage is placed into the top tank 2 from the water drop assembly 3 on the top tank 2 of the device. The water entering the top tank 2 falls on the top of the water blocking plate 41 and accumulates. With the continuous addition of water to be treated, the liquid level of the water above the water blocking plate 41 gradually increases, so that the buoyancy block 43 moves upward under the action of buoyancy. When the inclined part of the top surface of the buoyancy block 43 moves to a position close to a plurality of L-shaped frames 49 and squeezes the L-shaped frames 49, the L-shaped frames 49 move with the moving rods 46 in a direction away from the buoyancy block 43. At this time, the ring 410 moves to a position away from the buoyancy block 43, so that the U-shaped spring piece 41 1 is slightly deformed. During this process, the moving rod 46 moves with the blocking plate 47, and a certain gap is generated between the blocking plate 47 and the trumpet tube 48. During this process, the water located above the water blocking plate 41 flows into the trumpet tube 48 in the pipe 42 through the inlet groove 44, and flows out from the gap between the trumpet tube 48 and the blocking plate 47. This design makes it possible for the liquid level to be always higher than the inlet groove 44 opened on the pipe 42 each time the water is placed in the tray 8 located above, so that the water can enter each pipe 42 more evenly, thereby improving the uniformity of the water falling on the filling layer, which is conducive to the uniform and full contact between the introduced air and the water, thereby improving the effect of removing carbon dioxide from the aquaculture water. The design of the small block 45 makes the moving rod 46 keep moving horizontally.

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

[0036] It should be noted that the limit plate 10 is an arc-shaped plate whose internal curvature is adapted to the buoyancy block 43. The limit plate 10 is used to limit the buoyancy block 43 to ensure its movement in the up and down directions. The inner side of the limit plate 10 is rotatably connected with a ball 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 squeeze the L-shaped frame 49. At this time, under the elastic force of the U-shaped spring piece 411 itself, the annular side of the blocking plate 47 blocks the bell tube 48. It should be noted that the elastic force of the U-shaped spring piece 411 is greater than the pressure exerted by water on the blocking plate 47.

[0038] Specifically, Figures 2 to 8 As shown, a stay component 5 is provided inside and on the top of the water blocking plate 41, and the stay 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 provided inside the left side of the fixing frame 51, a first elastic membrane 53 is fixedly connected to the left side of the inside of the through groove 52, a limiting rod 54 is fixedly connected to the middle part of the first elastic membrane 53, and the right side of the limiting rod 54 is slidably connected to the fixing frame 51, a groove 55 is provided on the left side of the inside of the buoyancy block 43, and a clamping hole 56 is provided near the groove 55 in the inside of the buoyancy block 43, and a trigger component 6 is provided on the left part and the left side of the water blocking plate 41, and the trigger component 6 includes a circular hole 61 provided at the upper end of the water blocking plate 41 and below the buoyancy block 43, and a second elastic membrane 62 is fixedly connected to the top of the inner wall of the circular hole 61, and the water blocking plate A gas pressure sensor 63 is fixedly connected to the left side of the circular hole 61 inside 41. The gas pressure sensor 63 is a mature prior art and is not described in detail. The detection end of the gas pressure sensor 63 is inserted into the circular hole 61. The trigger assembly 6 also includes a transition groove 64 provided in the water blocking plate 41 and below the circular hole 61. The trigger assembly 6 also includes an empty groove 65 provided in the water blocking plate 41 and close to the inner wall of the top tank 2. The trigger assembly 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 empty groove 65, and is fixedly connected to a piston plate 67. The outer side of the piston plate 67 is fitted with the inner wall of the empty groove 65. The empty groove 65 is connected to the transition groove 64, and the transition groove 64 is connected to the through groove 52. The left part of the limit rod 54 is rotatably connected to a ball.

[0039] By adopting the above technical solution, when the liquid level rises, the buoyancy block 43 rises. In this process, since the liquid surface applies a large pressure to the second elastic membrane 62 above the circular hole 61, the second elastic membrane 62 is slightly deformed, so that the gas pressure sensor 63 detects the change in the pressure inside the circular hole 61. The gas pressure sensor 63 transmits a signal to the external control system to control the output shaft of the electric telescopic rod 66 to extend, so that the piston plate 67 moves 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 , so that the gas enters the interior of the through groove 52, and under the action of the gas pressure, the first elastic membrane 53 is deformed, and the limiting rod 54 moves to the right. When the inclined part of the top surface of the buoyancy block 43 moves to a position close to the multiple L-shaped frames 49, the left part of the limiting rod 54 contacts the left inner wall of the groove 55. When the inclined part of the top surface of the buoyancy block 43 squeezes the L-shaped frame 49, the left part of the limiting rod 54 is just stuck in the inside of the clamping hole 56, thereby limiting the buoyancy block 43. In this way, the blocking plate 47 can keep from blocking the trumpet 48 for a period of time, so that all the liquid above the water blocking plate 41 can be discharged.

[0040] This design prevents the buoyancy block 43 from moving downward immediately after the liquid level drops each time the water falls from the pipe 42, so that the annular side of the blocking plate 47 blocks the bell pipe 48, ensuring that more water is discharged each time, and the water is discharged more evenly from multiple pipes 42, thereby further improving the uniformity of water falling, facilitating the uniform and full contact between the introduced air and water, and further improving the effect of removing carbon dioxide in the aquaculture water.

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

[0042] Specifically, Figures 1 to 4 As shown, the water drop assembly 3 includes an inlet pipe 31 rotatably connected to the top of the top tank 2, the inner wall of the inlet pipe 31 is fixedly connected to a connecting frame 32, the bottom of the connecting frame 32 is fixedly connected to a guide cover 33, the ring side of the guide cover 33 is close to the inner wall of the top tank 2, a rotating joint 34 is installed on the top of the inlet pipe 31, and the top of the top tank 2 is provided with a driving component 12 for driving the inlet pipe 31 to rotate.

[0043] By adopting the above technical solution, the driving 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 a mature existing technology, and its principle and installation method will not be described in detail.

[0044] The water treated by the microfilter enters the interior of the rotary joint 34 and enters the top surface of the guide cover 33 from the inlet pipe 31. There is a moving gap between the ring side of the guide cover 33 and the interior of the top tank 2. As the inlet pipe 31 rotates with the guide cover 33, the water entering the top tank 2 flows down in a liquid film state along the inner wall of the top tank 2. This reduces the impact of the falling water on the water above the water blocking plate 41, so that the water above the water blocking plate 41 tends to be calm, so as to reduce the liquid fluctuation on the water blocking plate 41 and reduce the influence of the rising state of the buoyancy block 43, thereby reducing the situation that affects the uniform falling of the water.

[0045] Specifically, 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 tend to be calm.

[0047] Specifically, Figures 2 to 6 As shown, a dispersion component 7 is provided below the inlet pipe 31, and the dispersion component 7 includes a reciprocating screw 71 fixedly connected to the bottom of the guide cover 33, and the surface bottom of the reciprocating screw 71 is threadedly connected to a screw sleeve 72, and the bottom of the screw sleeve 72 is fixedly connected to a lifting rod 73, and the bottom annular array of the ring side of the lifting rod 73 is fixedly connected to a connecting plate 74, and the outer wall of the lifting rod 73 is slidably connected to the fixed frame 51. The dispersion component 7 also includes a discharge rack 75 slidably connected to the bottom of the pipeline 42, and the top two sides of the discharge rack 75 are slidably connected to sleeves 76, and the inner bottom end of the sleeve 76 is threadedly connected to a threaded rod 77, and the bottom of the ring side of the threaded rod 77 is fixedly connected to a scattering plate 78, and the inner wall of the discharge rack 75 is fixedly connected to a small plate 79, and the outer wall bottom of the threaded rod 77 is rotatably connected to the small plate 79, and a plurality of connecting plates 74 are fixedly connected to the discharge rack 75 on one side close to the discharge rack 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 be rotated, so that the screw sleeve 72 can move up and down with the lifting rod 73, so that the connecting plate 74 can 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 breaking plate 78 to break up the falling water, further improve the uniformity of the water falling, and facilitate the uniform and full contact between the introduced air and the water, thereby improving the effect of removing carbon dioxide in the aquaculture water.

[0049] It should be noted that the thread pitch at the top of the threaded rod 77 is relatively large, which is beneficial to reducing the resistance to movement so that when relative movement occurs between the threaded rod 77 and the sleeve 76, the threaded rod 77 can rotate smoothly. The thread provided on the threaded rod 77 and the threaded connection with the sleeve 76 are similar to the screw part and the flying saucer part of a hand-propelled flying saucer.

[0050] Working principle: gas enters from the air inlet pipe, takes out carbon dioxide and then enters the top of the water blocking plate 41 from the pipe 42, and is discharged from the top opening of the top tank 2. Sewage is placed into the top tank 2 from the water drop assembly 3 on the top tank 2 of the device. The water entering the top tank 2 falls and accumulates on the top of the water blocking plate 41. As the water to be treated is continuously added, the liquid level of the water above the water blocking plate 41 gradually increases, causing the buoyancy block 43 to move upward under the action of buoyancy. When the inclined part of the top surface of the buoyancy block 43 moves to a position close to the multiple L-shaped frames 49 and squeezes the L-shaped frames 49, the L-shaped frames 49 carry the moving rods 46 away from the buoyancy blocks. 43, at this time, the ring 410 moves to a position away from the buoyancy block 43, so that the U-shaped spring piece 411 is slightly deformed. In this process, the moving rod 46 moves with the blocking plate 47, and a certain gap is generated between the blocking plate 47 and the bell tube 48. In this process, the water above the water blocking plate 41 flows into the bell tube 48 in the pipe 42 through the inlet groove 44, and flows out from the gap between the bell tube 48 and the blocking plate 47. This design ensures that each time water is placed in the tray 8 at the top, the liquid level is always higher than the inlet groove 44 opened on the pipe 42, so that the water can enter each pipe 42 more evenly, so that The uniformity of water falling on the filling layer is improved. When the liquid level rises, the buoyancy block 43 rises. In this process, since the liquid surface applies a large pressure to the second elastic film 62 above the circular hole 61, the second elastic film 62 is slightly deformed. In this way, the gas pressure sensor 63 detects the change in the pressure inside the circular hole 61. The gas pressure sensor 63 transmits a signal to the external control system to control the output shaft of the electric telescopic rod 66 to extend, so that the piston plate 67 moves to the right. At this time, since the empty groove 65 is connected with 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 with the through groove 52 The buoyancy block 43 is connected, so that the gas enters the interior of the through groove 52. Under the action of the gas pressure, the first elastic membrane 53 is deformed, and the limiting rod 54 moves to the right. When the inclined part of the top surface of the buoyancy block 43 moves to a position close to the multiple L-shaped frames 49, the left part of the limiting rod 54 contacts the left inner wall of the groove 55. When the inclined part of the top surface of the buoyancy block 43 squeezes the L-shaped frame 49, the left part of the limiting rod 54 is just stuck in the inside of the clamping hole 56, thereby limiting the buoyancy block 43. In this way, the blocking plate 47 can keep from blocking the trumpet 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 with the connecting frame 32 and the guide cover 33, the reciprocating screw 71 can be rotated, so that the screw sleeve 72 can move up and down with the lifting rod 73, so that the connecting plate 74 can 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 breaking plate 78 to break up the falling water, further improve the uniformity of the water falling, and facilitate the uniform and full contact between the introduced air and the water, thereby improving the effect of removing carbon dioxide in the aquaculture water.
