Description

Technical Field

[0001] This disclosure relates to the field of purification and recycling technology, and in particular to a purification and recycling device for aquaculture water. Background Technology

[0002] Aquaculture is an important part of agricultural production, and modern aquaculture is becoming increasingly intensive. This necessitates the use of aquaculture equipment. Such equipment can greatly increase the survival rate of aquatic organisms and significantly reduce the workload of aquaculture workers. Existing purification equipment only filters the aquaculture water. Although activated carbon, a highly absorbent material, is used, harmful substances such as ammonia nitrogen and nitrite in the water only pass through the activated carbon once. Under these conditions, ammonia nitrogen and nitrite in the water cannot be fully removed, thus failing to provide a healthy and stable growth environment for aquaculture organisms.

[0003] According to a patent document with publication number CN219272301U, an aquaculture water purification and circulation device includes a base plate, a fish pond fixedly connected to the top of the base plate, a filter box fixedly connected to the top of the base plate, a filter screen fixedly connected to the inner wall of the filter box, a threaded rod fixedly connected to the inner wall of the filter box, a telescopic rod fixedly connected to the inner side wall of the filter box, a moving block fixedly connected to one end of the telescopic rod, a scraper fixedly connected to the bottom of the moving block, a discharge trough formed on the inner side wall of the filter box, and a rotating rod fixedly connected to the inner side wall of the discharge trough. This technical solution, in use, utilizes a set... The device consists of a filter box, discharge trough, filter screen, threaded rod, moving block, and scraper. The second motor drives the threaded rod to rotate, which in turn scrapes away dirt from the surface of the filter screen. The collection box collects the dirt. This device can clean the surface of the filter screen without clogging it, thus greatly improving the filtration effect. However, while this solution avoids filter clogging, it cannot quickly limit and fix the position of the filter screen during use. Furthermore, when the screen is fixed, centrifugal transmission of the filter screen is not possible, making it difficult to filter and remove impurities from the internal wastewater, which is inconvenient during use.

[0014] Optionally, a rotating rod is rotatably installed inside the fixed cylinder, a spiral plate is welded to the side of the rotating rod, and a rubber plate is fixed to one side of the spiral plate, the rubber plate being in contact with the inner wall of the fixed cylinder.

[0015] Optionally, a discharge cylinder is fixed to the bottom of the mixing tank, the discharge cylinder is connected to the fixed cylinder, and a connecting cylinder is fixed to the bottom of the mixing tank, one end of the connecting cylinder being movably installed on the top of the tank body.

[0016] The technical solution provided in this disclosure may include the following beneficial effects: This invention uses a ring seat installed inside a rotating barrel. The limiting groove on the ring seat cooperates with the limiting block to limit and fix the support rod. At the same time, the limiting groove and the limiting block cooperate to provide the necessary power support for the subsequent rotation of the ring seat. Later, when the support rod moves upward, the limiting block pushes the ring seat upward, and the upward movement of the ring seat facilitates subsequent disassembly. In addition, the support rod moves up and down under the push of the ring seat. When the support rod moves up and down, it changes the position and height of the stirring plate. The rotation of the stirring plate agitates the liquid, and the liquid is discharged faster under the rotation, which is beneficial to the recycling of water. In this invention, the ring seat is movably mounted on the side of the support rod via an arc-shaped block. The ring seat can drive the movement of the support rod through the arc-shaped block. In addition, the ring seat supports the support rod from the side, thereby effectively preventing the support rod from tilting and swaying due to centrifugal force when the rotating barrel rotates. In use, the servo motor drives the threaded column to rotate, and the threaded column pushes the positioning rod to rise initially. As the positioning rod rises, the lifting mechanism drives the connecting rod to move upward. As the connecting rod moves upward, it drives the piston column to move upward through the connecting column. The upward movement of the piston column causes the positioning column to drive the ring seat to move up and down. The displacement adjustment of different structures can be achieved through a single power mechanism. In this invention, when the piston seat moves upward, it compresses the space of the liquid at the top. Under the pressure, the liquid enters the interior of the fixed cylinder through the discharge hole. The discharge hole causes the materials to squeeze against each other, and the liquid is mixed under the mutual squeezing. The upward movement of the piston seat facilitates the complete discharge of the liquid inside the mixing tank. At the same time, after the piston seat moves to the top of the mixing tank, the lifting mechanism works to push the entire mixing tank upward. After the entire mixing tank moves upward, it is easy to open the space at the top of the tank, so that the filter bag inside the tank can be disassembled and cleaned.

[0017] In this invention, when the liquid inside the feed hopper enters from top to bottom between the spiral plates, the spiral plates are spirally distributed inside the fixed cylinder. The spiral plates obstruct the flow of liquid, allowing a large amount of liquid to preferentially enter the mixing tank. Later, after the piston seat has moved completely upwards to the top of the mixing tank and stops moving, the drive motor is activated to cause the rotating tank to centrifuge. Under centrifugal force, the filter bag adheres to the inner wall of the rotating tank, and the filter bag, under centrifugal action, causes the liquid inside to move outwards and be discharged. After the liquid is discharged between the stirring plates, the stirring plates, through their centrifugal force, discharge the liquid outwards through the drain pipe, thus achieving circulation. Additional aspects and advantages of this disclosure will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this disclosure.

[0020] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0021] like Figures 1 to 9As shown, an aquaculture water purification and circulation device includes: a base 1, with support seats 2 welded to the sides of the base 1, reinforcing seats 3 welded between the support seats 2, movable seats 4 movably mounted on the top of the support seats 2, a tank body 5 fixed between the movable seats 4, and a drain pipe 6 fixed to the side of the tank body 5; a centrifugal assembly, including a rotating tank 15, with a slot 18 on the rotating tank 15, a support rod 19 movably mounted inside the slot 18, a stirring plate 20 welded to the side of the support rod 19, a rotating column 27 fixed to the bottom of the rotating tank 15, a drive motor 28 mounted at the bottom of the rotating column 27, and the drive motor 28 fixedly mounted to the bottom of the tank body 5; and a limiting assembly 17, including a limiting seat 22 movably mounted on the side of the support rod 19, a positioning column 23 welded to the limiting seat 22, and a fixing ring 26 welded to one end of the positioning column 23. The rotating drum 15 drives the stirring plate 20 to rotate. The stirring plate 20 has an opening, which reduces the deformation caused by liquid impact. The stirring plate 20 fits into the inner wall of the rotating drum 15. Later, when impurities adhere to the inner wall of the rotating drum 15, the rotation of the stirring plate 20 can scrape and clean the inner wall of the rotating drum 15. Under the centrifugal rotation of the rotating drum 15, the liquid enters between the stirring plates 20 through the opening on the rotating drum 15. As the rotating drum 15 centrifuges, the stirring plate 20 can make the liquid inside be quickly discharged outward through the drain pipe 6 for circulation. When the ring seat 24 drives the support rod 19 to move up and down, the support rod 19 drives the ring seat 24 to move a short distance inside the rotating drum 15 through the limiting block 30. The up and down movement of the ring seat 24 causes the bottom filter bag 25 to shake up and down. The up and down shaking of the filter bag 25 makes it easier for impurities adhering to the inner wall to fall downward. After the impurities fall to the bottom of the filter bag 25, they are easy to collect later.

[0022] In this embodiment, a mixing tank 11 is movably mounted on the top of the tank body 5. A feeding hopper 12 is fixed to the top of the mixing tank 11. A feeding pipe 13 and a water inlet pipe 14 are fixed to the feeding hopper 12. A connecting rod 10 is movably mounted on the top of the mixing tank 11. A fixing bolt 16 is rotatably mounted on the connecting rod 10. A telescopic column 9 is fixed to one end of the connecting rod 10. A lifting mechanism 7 is movably mounted on the telescopic column 9. A limit ring 8 is fixed to the side wall of the lifting mechanism 7. A bearing seat 37 is installed at the bottom of the lifting mechanism 7. A positioning rod 38 is movably mounted on the bearing seat 37. A cavity 44 is opened inside the support base 2. The positioning rod 38 is slidably installed inside the cavity 44.

[0023] It is understood that the lifting mechanism 7 is a linear reciprocating electric actuator. The electric actuator is connected to an external telescopic switch via a wire. The telescopic switch controls the linear extension and retraction of the lifting mechanism 7. In use, the servo motor 40 drives the threaded column 39 to rotate. The threaded column 39 rotates on the threaded seat 43. As the threaded column 39 rotates, the threaded seat 43 pushes the positioning rod 38 to move vertically inside the cavity 44 of the support seat 2. After the threaded column 39 pushes the positioning rod 38 to fully rise, the lifting mechanism 7, under the push of the positioning rod 38, drives the connecting column 35 to move upward via the connecting rod 10. When the connecting column 35 moves upward, it pushes the liquid at the top of the piston seat 33 to move upward. The rise of the piston seat 33 compresses the space at the top, and the liquid, under compression, re-enters the interior of the fixed cylinder 31 through the discharge hole 32. The feed holes 32 are inclinedly distributed around the spiral plate 42. When the feed holes 32 are fed in under high pressure, they can drive the spiral plate 42 and the rotating rod 41 to rotate. When the liquid is squeezed through the feed holes 32, the materials can be mixed again. In the early stage, the materials enter the sewage and sodium bicarbonate at the same time through the feed pipe 13 and the water inlet pipe 14. When entering, they are initially mixed through the feed hopper 12. A large amount of liquid enters the filter bag 25 through the bottom of the fixed cylinder 31. A small amount of liquid enters the mixing tank 11 through the discharge holes 32. Later, the liquid in the mixing tank 11 is squeezed and mixed again under one end of the piston seat 33 and discharged, which is conducive to the mixing of liquids in the later stage. After sodium bicarbonate comes into contact with sewage, it can reduce the pH value of sewage, thereby completing the water purification treatment. In this embodiment, a servo motor 40 is fixedly installed inside the cavity 44. A threaded post 39 is mounted on the servo motor 40. The threaded post 39 is rotatably mounted inside the positioning rod 38. A threaded seat 43 is welded inside the positioning rod 38, and the threaded post 39 is rotatably mounted on the threaded seat 43. A ring seat 24 is movably installed inside the rotating barrel 15. A filter bag 25 is fixed to the bottom of the ring seat 24. A limit groove 29 is formed on the outer wall of the ring seat 24. A limit block 30 is movably installed inside the limit groove 29. One end of the limit block 30 is welded to the inner wall of the support rod 19. An arc-shaped block 21 is welded to the outer wall of the support rod 19. The arc-shaped block 21 is movably installed on the top of the limiting seat 22. Protrusions are welded to both sides of the bottom of the support rod 19. A groove is opened on the inner wall of the slot 18. The protrusion is slidably installed inside the groove. In the early stage, the water in the breeding pond is filtered by other filtration equipment to remove residual feed and solid feces. The pre-filtered water then enters the mixing tank 11 for mixing. When the liquid in the feed hopper 12 enters between the spiral plates 42 from top to bottom, the spiral plates 42 are spirally distributed inside the fixed cylinder 31. Under the obstruction of the spiral plates 42, a large amount of liquid preferentially enters the mixing tank 11. After the piston seat 33 moves completely upward to the top of the mixing tank 11, it stops moving. The drive motor 28 is started to make the rotating tank 15 centrifuge. Under the centrifugation of the rotating tank 15, the filter bag 25 adheres to the inner surface of the rotating tank 15. The filter bag 25, under centrifugal force, moves the liquid inside out and discharges it. After the liquid is discharged between the stirring plates 20, the stirring plates 20 use their centrifugal force to discharge the liquid out through the drain pipe 6 to achieve circulation. When the rotating tank 15 rotates, the ring seat 24 is installed inside the rotating tank 15. The limiting groove 29 on the ring seat 24 cooperates with the limiting block 30 to limit and fix the support rod 19. At the same time, the limiting groove 29 and the limiting block 30 cooperate to provide the necessary power support for the subsequent rotation of the ring seat 24. Later, when the support rod 19 moves upward, the limiting block 30 pushes the ring seat 24 to move upward. The upward movement of the ring seat 24 facilitates the subsequent disassembly. In addition, the support rod 19 moves up and down under the push of the ring seat 24. When the support rod 19 moves up and down, it changes the position and height of the stirring plate 20. The rotation of the stirring plate 20 causes the liquid to rotate, and the liquid is discharged out faster under the rotation, which is beneficial to the recycling of water.

[0024] In this embodiment, a fixed cylinder 31 is fixed inside the mixing tank 11. A discharge hole 32 is formed on the fixed cylinder 31. A piston seat 33 is movably mounted on the fixed cylinder 31. A sealing ring is fixed to the side of the piston seat 33, and a fixing hole 34 is formed on the piston seat 33. A positioning pin 23 is movably mounted inside the fixing hole 34. The diameter of the fixing ring 26 is larger than the diameter of the fixing hole 34. A sealing ring is fixed to the inner wall of the fixing hole 34. A connecting pin 35 is welded to the piston seat 33. One end of the connecting pin 35 has a threaded hole 36, and a fixing bolt 16 is rotatably mounted inside the threaded hole 36. A rotating rod 41 is rotatably mounted inside the fixed cylinder 31. A spiral plate 42 is welded to the side of the rotating rod 41. A rubber plate is fixed to one side of the spiral plate 42, and the rubber plate is in contact with the inner wall of the fixed cylinder 31. A discharge cylinder is fixed to the bottom of the mixing tank 11, and the discharge cylinder is connected to the fixed cylinder 31. A connecting cylinder is fixed to the bottom of the mixing tank 11, and one end of the connecting cylinder is movably installed on the top of the tank body 5.

[0025] Understandably, when it is necessary to disassemble the ring seat 24 and filter bag 25 inside the rotating barrel 15 later, the lifting mechanism 7 is activated to move the telescopic column 9 upward. The movement of the telescopic column 9 further increases the height of the mixing barrel 11. After the mixing barrel 11 rises, the space at the top of the barrel 5 opens, and the ring seat 24 is moved upward to separate the limiting block 30 and the limiting groove 29. After separation, the filter bag 25 is moved upward and folded. After folding, the ring seat 24 is moved upward for disassembly. When it is necessary to disassemble the mixing barrel 11, the fixing bolt 16 is rotated from the inside of the threaded hole 36. When the connecting rod 10 is partially disconnected from the connecting column 35, the mixing tank 11 can be removed from the top of the tank body 5. After the mixing tank 11 is removed, the space at the top of the tank body 5 is fully opened, which facilitates a thorough cleaning of the space inside the tank body 5. When the piston seat 33 moves to the bottom of the discharge hole 32, it can stop moving. After the piston seat 33 stops moving, the space at the top is reduced to the minimum state. The amount of liquid entering the mixing tank 11 through the discharge hole 32 is reduced, allowing the liquid to fall directly into the rotating tank 15 through the fixed cylinder 31, thereby achieving rapid purification and circulation of water.

[0026] Working Principle: During use, wastewater and sodium bicarbonate are simultaneously introduced through the feed pipe 13 and water inlet pipe 14. Initial mixing occurs through the feed hopper 12 upon entry. A large amount of liquid preferentially enters the filter bag 25 through the bottom of the fixed cylinder 31, while a small portion enters the mixing tank 11 through the discharge hole 32. Later, the liquid inside the mixing tank 11 is squeezed and mixed again by one end of the piston seat 33, thus facilitating further mixing. Sodium bicarbonate, upon contact with wastewater, lowers the pH value of the wastewater, thereby completing the water purification process. The servo motor 40 drives the threaded column 39 to rotate. The threaded column 39 rotates on the threaded seat 43. As the threaded column 39 rotates, the threaded seat 43 pushes the positioning rod 38 vertically within the cavity 44 of the support base 2. After the threaded column 39 pushes the positioning rod 38 completely upwards, the positioning rod 38... Driven by the lifting mechanism 7, the connecting rod 10 drives the connecting column 35 to move upward. When the connecting column 35 moves upward, it pushes the liquid at the top of the piston seat 33 to move upward. The rise of the piston seat 33 compresses the space at the top. Under the pressure, the liquid enters the interior of the fixed cylinder 31 again through the discharge hole 32. The discharge hole 32 is inclinedly distributed around the spiral plate 42. When the discharge hole 32 feeds in under high pressure, it can push the spiral plate 42 and the rotating rod 41 to rotate. When the liquid is squeezed through the discharge hole 32, the materials can be mixed again. When the piston seat 33 moves to the bottom of the discharge hole 32, it can stop moving. After the piston seat 33 stops moving, the space at the top is reduced to the minimum state. The amount of liquid entering the mixing tank 11 through the discharge hole 32 is reduced, and the liquid can fall directly into the interior of the rotating tank 15 through the fixed cylinder 31, thereby realizing the rapid purification and circulation of water. Subsequently, the drive motor 28 is started to centrifuge the rotating drum 15. Under the centrifugal force of the rotating drum 15, the filter bag 25 adheres to the inner wall of the rotating drum 15. The filter bag 25 moves the liquid inside out under the centrifugal force and is discharged. After the liquid is discharged between the stirring plates 20, the stirring plates 20 use their centrifugal force to discharge the liquid out through the drain pipe 6 to achieve circulation. When the rotating drum 15 rotates, the ring seat 24 is installed inside the rotating drum 15. The limiting groove 29 on the ring seat 24 cooperates with the limiting block 30 to limit and fix the support rod 19. At the same time, the limiting groove 29 and the limiting block 30 cooperate to provide the necessary power support for the subsequent rotation of the ring seat 24. Later, when the support rod 19 moves upward, the limiting block... 30 pushes the ring seat 24 upward, which facilitates later disassembly. Additionally, the support rod 19 moves up and down under the push of the ring seat 24. This movement changes the position and height of the stirring plate 20, causing the liquid to rotate and accelerate its outward discharge, thus promoting water recycling. Later, when it is necessary to disassemble the ring seat 24 and filter bag 25 inside the rotating tank 15, the lifting mechanism 7 is activated to move the telescopic column 9 upward. This movement further increases the height of the mixing tank 11. After the mixing tank 11 rises, the space at the top of the tank 5 opens, allowing the ring seat 24 to move upward and separate the limiting block 30 from the limiting groove 29. After separation... Fold the filter bag 25 upwards. After folding, move the ring seat 24 upwards for disassembly. When disassembling the mixing tank 11, rotate the fixing bolt 16 to separate it from the inside of the threaded hole 36. The connecting rod 10 loses its connection with the connecting column 35, allowing the mixing tank 11 to be removed from the top of the tank body 5. After the mixing tank 11 is removed, the space at the top of the tank body 5 is completely opened, facilitating a thorough cleaning of the interior space of the tank body 5. The rotating tank 15 drives the rotation of the stirring plate 20. The stirring plate 20 has an opening, which reduces the deformation caused by liquid impact on the stirring plate 20. The stirring plate 20 fits into the inner wall of the rotating tank 15. Later, when impurities adhere to the inner wall of the rotating tank 15, they are removed by the stirring plate. The rotation of the 20 can scrape and clean the inner wall of the rotating barrel 15. Under the centrifugal rotation of the rotating barrel 15, the liquid enters between the stirring plates 20 through the opening on the rotating barrel 15. As the rotating barrel 15 centrifuges, the stirring plates 20 can make the liquid inside be quickly discharged outward through the drain pipe 6 for circulation under the centrifugal swing. When the ring seat 24 drives the support rod 19 to move up and down, the support rod 19 drives the ring seat 24 to move a short distance inside the rotating barrel 15 through the limiting block 30. The up and down movement of the ring seat 24 realizes the up and down shaking of the bottom filter bag 25. The up and down shaking of the filter bag 25 makes it easy for impurities adhering to the inner wall to fall downward. After the impurities fall to the bottom of the filter bag 25, they are easy to collect later.
