Description

Technical Field

[0001] This invention relates to the field of marine aquaculture technology, specifically to a marine aquaculture wastewater treatment device and its usage method. Background Technology

[0002] Marine aquaculture is a production activity that utilizes shallow sea beaches and tidal flats along the coast to cultivate marine aquatic economic animals and plants. It includes shallow sea aquaculture, tidal flat aquaculture, and harbor aquaculture. The main species cultivated in marine aquaculture are fish, shrimp, crabs, shellfish, algae, and other economic animals such as sea cucumbers.

[0003] Chinese patent (application number CN202010321157.X) discloses a wastewater treatment device for aquaculture seawater. The device uses a servo motor to drive the first connecting rod to rotate, and the transfer bar can move horizontally back and forth, so that the air nozzle sprays air onto the mesh of the filter screen above it to prevent the filter screen from becoming clogged.

[0004] However, the aforementioned wastewater treatment equipment for aquaculture seawater has some problems in use:

[0005] 1. During seawater aquaculture, some impurities, aquatic plants and other floating objects will float on the surface of the wastewater. When treating seawater aquaculture wastewater after a period of use, it is impossible to collect the floating objects on the surface of the wastewater through filtration.

[0006] 2. When fish excrement, feed, and granular medicines in the seawater can be recycled during marine aquaculture, the size of these particles is inconsistent, making it impossible to classify them. A single filter component cannot adjust the size of the filter holes when filtering particles.

[0007] Based on the above, a marine aquaculture wastewater treatment device and its usage method are proposed. Summary of the Invention

[0008] The purpose of this invention is to provide a marine aquaculture wastewater treatment device and its usage method to solve the problems mentioned in the background art.

[0009] The objective of this invention can be achieved through the following technical solutions:

The lifting rod is threadedly rotatably connected to the fixing member on one side.

[0013] Preferably, the moving component includes a chute, which is opened at both ends of the water storage frame. An electric slider is provided in the chute. There are two electric sliders. A connecting plate is fixedly installed on the upper end of the two electric sliders. Scrapers are slidably installed on both sides of the connecting plate. The scrapers on both sides are respectively in contact with the inner wall of the water storage frame.

[0014] Preferably, the upper surface of the outer frame is provided with synchronization grooves on both sides, and the synchronization grooves on both sides correspond to the sliding grooves on both sides respectively. A sliding rod is slidably installed in the synchronization grooves on both sides. A telescopic rod is fixedly installed on the side of the sliding rods on both sides that are close to each other. A limiting component is fixedly installed on the end of the telescopic rod away from the sliding rod. A compression spring is sleeved on the outside of the telescopic rod, and the compression spring is located between the limiting component and the sliding rod to abut against each other.

[0015] Preferably, the salvage unit includes an outer cylinder with a rectangular groove circumferentially opened on the lower side of the outer cylinder. A salvage ring is slidably installed on the inner side wall of the outer cylinder. A support frame is fixedly installed on the upper surface of the outer cylinder. A hydraulic rod is fixedly installed in the middle of the lower surface of the support frame. A circular plate is fixedly installed on the end of the hydraulic rod away from the support frame. Fixed rods are symmetrically arranged on the left and right sides of the circular plate away from the hydraulic rod. A bottom plate is fixedly installed between the fixed rods on both sides. Floating parts are symmetrically arranged on both sides of the lower surface of the bottom plate.

[0016] Preferably, the retrieval ring is arc-shaped and has through holes on its sidewalls. A collection box is detachably installed on one side of the inner cavity of the outer cylinder. A U-shaped frame is fixedly installed at the upper end of the outer cylinder. A screw is rotatably installed in the middle of the U-shaped frame. A hanging plate is rotatably installed on the screw. The end of the hanging plate away from the screw is fixedly connected to the retrieval ring. A lifting motor is fixedly installed in the middle of the upper surface of the U-shaped frame.

[0017] Preferably, a rotating plate is rotatably mounted on the upper surface of the base plate, and teeth are arranged circumferentially along the inner side of the rotating plate along its axis. Locking components are slidably mounted on both sides of the base plate to facilitate the connection between the rotating plate and the base plate. A retrieval motor is fixedly mounted in the middle of the upper surface of the rotating plate. Gears are rotatably mounted on both sides inside the rotating plate. A connecting shaft is fixedly mounted on one side of the gear and the output end of the retrieval motor. Pulleys are fixedly mounted on the top of the connecting shafts on both sides. A belt is provided between the pulleys. A paddle is fixedly mounted circumferentially on the outer side of the rotating plate.

[0018] Preferably, two support rods are detachably installed on both sides of the upper surface of the rotating plate. Each support rod has a sweeping plate fixedly installed at its bottom end. The sweeping plate is used to scrape off the impurities collected in the retrieval ring and make them fall into the collection box for collection and processing. Baffles are installed on both sides of the sweeping plate by torsion springs. The baffles are used to block the impurities.

[0019] Preferably, another object of the present invention is to provide a method of using a marine aquaculture wastewater treatment device, comprising the following steps:

[0020] S1: Wastewater surface treatment:

[0021] Turn on the salvage motor. The salvage motor drives the gear on one side to rotate through the pulley and belt. When the gear on one side rotates, it meshes with the inside of the rotating plate, thereby driving the rotating plate to rotate. When the rotating plate rotates, it drives the paddle to rotate, thereby stirring the surface of the wastewater and causing the impurities on the surface of the wastewater to pass through the rectangular groove and be located inside the outer cylinder. Then, the salvage ring salvages and collects the impurities.

[0022] S2: Wastewater sorting and recycling:

[0023] The filter holes in the middle of the lifting plate filter and collect excrement, feed, and drug particles in the marine aquaculture wastewater. By rotating the adjusting rod, the adjusting rod drives the drive wheel to rotate. When the drive wheel rotates, it meshes with the adjusting plate, thereby driving the adjusting plate to rotate. Since the adjusting plate is rotatably connected to the outer side of the rotating ring, the size of the filter holes on the lifting plate is adjusted when the adjusting plate rotates, so as to realize the recovery of particles of different sizes. By rotating the lifting rod, the lifting rod drives the rack plate to descend through the lifting wheel. The rack plate drives the lifting plate to adjust the height, so that the fish on the lifting plate can rise and fall synchronously with the water level line during wastewater treatment. Pulling the lever upward, the lever drives the unblocking plate to raise the unblocking rod to clear the blocked filter holes, preventing particles in the wastewater from clogging and preventing them from falling and being recovered.

[0024] S3: Wastewater purification:

[0025] By turning on the water pump in the water exchange pipe, the wastewater inside the water storage box is drawn into the purification tank. The purification tank purifies the wastewater from seawater aquaculture so that it can be reused after treatment.

[0026] The beneficial effects of this invention are:

[0027] 1. This invention uses a lifting rod to rotate a lifting wheel. When the lifting wheel rotates, it meshes with a rack plate, causing the rack plate to descend. As the rack plate descends, it causes the lifting plate to descend as well. When the lifting plate descends, the aquatic organisms in the water storage frame descend synchronously with the water level, thus avoiding the need to remove the aquatic organisms in advance when recycling and treating marine aquaculture wastewater.

[0028] 2. This invention uses a hydraulic rod and an outer cylinder. The lifting motor reverses to raise the suspended plate. When the suspended plate rises, it drives the retrieval ring to lift the debris. At this time, wastewater drips through the through hole on the retrieval ring. Then, the retrieval ring rises until its inner cavity is in contact with the bottom of the sweeping plate. The support rod rotates along the axis of the rotating plate, sweeping the impurities on the retrieval ring into the collection box for unified collection.

[0029] 3. This invention uses an adjusting rod and a drive wheel. The adjusting rod drives the drive wheel to rotate, and the drive wheel rotates the adjusting plate. When the adjusting plate rotates, it adjusts the size of the filter holes on the lifting plate, so as to facilitate the classification and recycling of particles of different sizes such as excrement and drug particles in wastewater.

[0030] 4. This invention uses a pull rod and a clearing rod. Pulling the pull rod upward causes it to rise via a clearing plate to clear the clogged filter holes, thus preventing particulate matter in the wastewater from clogging and preventing the particles from falling and being recycled.

[0031] 5. This invention sets up a water exchange pipe and a purification tank. The water pump is turned on to draw the wastewater inside the water storage frame into the purification tank through the water exchange pipe. The purification tank then purifies the wastewater from the marine aquaculture before reuse. Attached Figure Description

[0048] 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.

[0049] like Figure 1 , Figure 2 As shown, a marine aquaculture wastewater treatment device includes a base 1, an outer frame 2 fixedly installed on one side of the upper surface of the base 1, a water storage unit 3 provided in the inner cavity of the outer frame 2, a scooping unit 5 provided in the water storage unit 3, the water storage unit 3 is used to collect and treat impurities on the surface during marine aquaculture, a moving component 4 is provided in the water storage unit 3, a purification box 8 fixedly installed on the other side of the upper surface of the base 1, the purification box 8 is used to purify the wastewater from marine aquaculture for reuse, and a water exchange pipe 7 is connected between the purification box 8 and the water storage unit 3.

[0050] The water storage unit 3 includes a water storage frame 31, which is slidably connected to the inner wall of the outer frame 2. The inner walls of the water storage frame 31 have grooves, in which a lifting plate 32 is placed. An adjusting plate 33 is rotatably installed in the middle of the lower surface of the lifting plate 32. A rotating ring 34 is rotatably installed in the middle of the adjusting plate 33. Filter holes are opened in the middle of the lifting plate 32 and the middle of the adjusting plate 33 respectively. A pull rod 35 is slidably installed between the lifting plate 32 and the rotating ring 34. There are two pull rods 35, and a drain plate 36 is fixedly installed at the bottom of the pull rods 35 on both sides.

[0051] A dredging rod 37 is arranged on the upper end face of the dredging plate 36. It is rotatably connected to the lifting plate 32 through the adjusting plate 33 and the filter holes of the adjusting plate 33 and the lifting plate 32 correspond. When it is necessary to classify and discharge excrement, feed, drug particles, etc. in the marine aquaculture wastewater, since the excrement, feed, and drug particles are of different sizes, the adjusting plate 33 is rotated to adjust the size of the filter holes in the middle of the lifting plate 32.

[0052] like Figure 7 As shown, the adjusting plate 33 has teeth on its outer circumference, and a drive wheel 38 is provided on one side of the adjusting plate 33. The drive wheel 38 is rotatably connected to the lifting plate 32. A rotating shaft is fixedly installed in the middle of the drive wheel 38. The rotating shaft passes through the lifting plate 32 and an adjusting rod 39 is detachably installed. A sealing plate 390 is fixedly installed at the bottom of the water storage frame 31. A collection box 391 is provided on the lower surface of the sealing plate 390. The side walls of the collection box 391 and the sealing plate 390 are both provided with positioning grooves. An insert plate 392 is placed in the positioning groove. A rack plate 393 is fixedly installed on both sides of the upper surface of the lifting plate 32.

[0053] Both sides of the upper surface of the water storage frame 31 are fixedly installed with fasteners 394. A lifting wheel 396 is rotatably installed on the upper part of the fastener 394. The lifting wheel 396 meshes with the rack plate 393. A lifting rod 395 is fixedly installed in the middle of the lifting wheel 396 on one side. The lifting rod 395 is threadedly connected to the fastener 394 on one side. The collection box 391 facilitates the unified collection of particulate matter in the wastewater that falls into the collection box 391 through the filter holes.

[0054] When wastewater is discharged, the water level continuously drops. At this time, the lifting rod 395 is rotated clockwise. When the lifting rod 395 rotates, it drives the lifting wheel 396 to rotate. When the lifting wheel 396 rotates, it engages with the rack plate 393, thereby driving the rack plate 393 to descend. When the rack plate 393 descends, it drives the lifting plate 32 to descend. When the lifting plate 32 descends, the aquatic organisms in the water storage frame 31 descend synchronously with the water level, avoiding the need to salvage the aquatic organisms in advance when recycling and treating marine aquaculture wastewater.

[0055] like Figure 2 , Figure 3 As shown, the moving component 4 includes a slide 41, which is located at both ends of the water storage frame 31. Two electric sliders are installed inside the slide 41. A connecting plate 42 is fixedly mounted on the upper ends of both electric sliders. Scrapers 43 are slidably mounted on both sides of the connecting plate 42. The scrapers 43 on both sides are respectively in contact with the inner wall of the water storage frame 31. When cleaning the inner wall of the water storage frame 31, the electric sliders are activated, causing the connecting plate 42 to move back and forth. The movement of the connecting plate 42 causes the scrapers 43 to move, thus cleaning the dirt on the inner wall of the water storage frame 31.

[0056] Synchronous grooves 44 are provided on both sides of the upper surface of the outer frame 2. The synchronous grooves 44 on both sides correspond to the sliding grooves 41 on both sides. Sliding rods 45 are slidably installed in the synchronous grooves 44 on both sides. Telescopic rods are fixedly installed on the side of the sliding rods 45 that are close to each other. A limiting member 46 is fixedly installed on the end of the telescopic rod away from the sliding rod 45. A compression spring 47 is sleeved on the outside of the telescopic rod. The compression spring 47 is located between the limiting member 46 and the sliding rod 45 and abuts against each other. The setting of the compression spring 47 can fix the limiting member 46 at one end of the telescopic rod to the scraper 43, so as to prevent the scraper 43 from falling off when scraping the inner cavity side wall of the water storage frame 31.

[0057] The salvage unit 5 includes an outer cylinder 51. A rectangular groove is circumferentially opened on the lower side of the outer cylinder 51. A salvage ring 52 is slidably installed on the inner side wall of the outer cylinder 51. A support frame 53 is fixedly installed on the upper surface of the outer cylinder 51. A hydraulic rod 54 is fixedly installed in the middle of the lower surface of the support frame 53. A circular plate 55 is fixedly installed on the end of the hydraulic rod 54 away from the support frame 53. Fixing rods 56 are symmetrically arranged on the side of the circular plate 55 away from the hydraulic rod 54. A base plate 57 is fixedly installed between the fixing rods 56 on both sides.

[0058] like Figure 8 , Figure 11 As shown, floating elements 58 are symmetrically arranged on both sides of the lower surface of the base plate 57. The floating elements 58 allow the salvage unit 5 to float on the surface of the wastewater, so as to facilitate the salvage unit 5 to salvage impurities on the surface of the marine aquaculture wastewater. By opening the hydraulic rod 54 and pushing it forward, the hydraulic rod 54 drives the outer cylinder 51 to block the impurities floating on the surface of the wastewater, so as to facilitate the subsequent salvage and treatment of the impurities.

[0059] The retrieval ring 52 is arc-shaped and has through holes on its side wall. A collection box 520 is detachably installed on one side of the inner cavity of the outer cylinder 51. A U-shaped frame 521 is fixedly installed at the upper end of the outer cylinder 51. A screw 522 is rotatably installed in the middle of the U-shaped frame 521. A hanging plate 523 is rotatably installed on the screw 522. The end of the hanging plate 523 away from the screw 522 is fixedly connected to the retrieval ring 52. A lifting motor 524 is fixedly installed in the middle of the upper surface of the U-shaped frame 521. The output end of the lifting motor 524 is fixedly connected to the screw 522.

[0060] When retrieval of impurities floating on the surface of wastewater, the hydraulic rod 54 is activated and pushed forward. As the hydraulic rod 54 is pushed forward, it drives the outer cylinder 51 to block the impurities floating on the surface of the wastewater. Then, the lifting motor 524 on the frame 521 is turned forward. The lifting motor 524 drives the screw 522 to rotate. When the screw 522 rotates, it drives the hanging plate 523 to move down. When the hanging plate 523 moves down, it drives the retrieval ring 52 to descend and collect the floating objects blocked inside the outer cylinder 51. Then, the lifting motor 524 reverses, which drives the hanging plate 523 to rise. When the hanging plate 523 rises, it drives the retrieval ring 52 to lift the retrieved debris. At this time, the wastewater drips through the through hole opened on the retrieval ring 52. Then, the retrieval ring 52 is raised until the inner cavity of the retrieval ring 52 is in contact with the bottom of the sweeping plate 68.

[0061] like Figure 8 , Figure 9As shown, a rotating plate 61 is rotatably mounted on the upper surface of the base plate 57. Teeth are arranged circumferentially along the axis of the inner side of the rotating plate 61. Locking parts 62 are slidably mounted on both sides of the base plate 57. The locking parts 62 facilitate the connection between the rotating plate 61 and the base plate 57. A retrieval motor 63 is fixedly mounted in the middle of the upper surface of the rotating plate 61. Gears 64 are rotatably mounted on both sides inside the rotating plate 61. A connecting shaft is fixedly mounted between the gear 64 on one side and the output end of the retrieval motor 63. A pulley 65 is fixedly mounted on the top of the connecting shaft on both sides.

[0062] A belt 66 is provided between the pulleys 65, and a paddle 59 is fixedly installed on the outer circumference of the rotating plate 61. When the impurities dredged from the marine aquaculture wastewater by the dredging ring 52 are recovered, the dredging motor 63 is turned on. The dredging motor 63 drives the gear 64 on one side to rotate through the pulleys 65 and the belt 66. When the gear 64 on one side rotates, it drives the rotating plate 61 to rotate. When the rotating plate 61 rotates, it drives the support rods 67 on both sides to rotate along the axis of the rotating plate 61. When the support rods 67 on both sides rotate, they drive the sweeping plate 68 to sweep the impurities on the dredging ring 52 into the collection box 520 for unified collection.

[0063] Two support rods 67 are detachably installed on both sides of the upper surface of the rotating plate 61. A sweeping plate 68 is fixedly installed at the bottom of each support rod 67 on both sides. The sweeping plate 68 is used to scrape the impurities collected in the retrieval ring 52 and make them fall into the collection box 520 for collection and processing. Baffles 69 are installed on both sides of the sweeping plate 68 through torsion springs. The baffles 69 are used to block the impurities.

[0064] like Figures 1-13 As shown, another objective of the present invention is to provide a method for using a marine aquaculture wastewater treatment device, comprising the following steps:

[0065] S1: Wastewater surface treatment:

[0066] Turn on the salvage motor 63. The salvage motor 63 drives the gear 64 on one side to rotate through the pulley 65 and belt 66. When the gear 64 rotates, it meshes with the inner side of the rotating plate 61, thereby driving the rotating plate 61 to rotate. When the rotating plate 61 rotates, it drives the paddle 59 to rotate, thereby agitating the wastewater surface and causing impurities on the wastewater surface to pass through the rectangular groove and be located inside the outer cylinder 51. Then, the salvage ring 52 salvages and collects the impurities.

[0067] S2: Wastewater sorting and recycling:

[0068] The filter holes in the middle of the lifting plate 32 filter and collect excrement, feed, and drug particles in the marine aquaculture wastewater. By rotating the adjusting rod 39, the adjusting rod 39 drives the drive wheel 38 to rotate. When the drive wheel 38 rotates, it meshes with the adjusting plate 33, thereby driving the adjusting plate 33 to rotate. Since the adjusting plate 33 is rotatably connected to the outer side of the rotating ring 34, the size of the filter holes on the lifting plate 32 is adjusted when the adjusting plate 33 rotates, so as to realize the recovery of particles of different sizes. By rotating the lifting rod 395, the lifting rod 395 drives the rack plate 393 to descend through the lifting wheel 396. The rack plate 393 drives the lifting plate 32 to adjust its height, so that the fish on the lifting plate 32 can rise and fall synchronously with the water level line during wastewater treatment. Pulling the pull rod 35 upward, the pull rod 35 drives the unblocking rod 37 to rise through the unblocking plate 36 to unblock the blocked filter holes, preventing particles in the wastewater from clogging and preventing particles from falling and being recovered.

[0069] S3: Wastewater purification:

[0070] By turning on the water pump in the water exchange pipe 7, the wastewater inside the water storage frame 31 is drawn into the purification tank 8. The purification tank 8 purifies the wastewater from marine aquaculture so that it can be reused after treatment.

[0071] In use, this invention first treats the surface of the wastewater from marine aquaculture to collect floating weeds and other impurities. The retrieval motor 63 is then activated, driving a gear 64 on one side via a pulley 65 and belt 66. This gear 64 meshes with the inner side of a rotating plate 61, causing the plate to rotate. The rotating plate 61 then drives a paddle 59, which in turn moves the wastewater surface, causing impurities to pass through a rectangular groove and be positioned inside the outer cylinder 51. Next, the hydraulic rod 54 is activated and pushed forward, causing the outer cylinder 51 to block the floating impurities. Then, the lifting motor 524 on the frame 521 is activated and rotates forward, driving a screw 522. This screw 522 lowers the hanging plate 523, which in turn lowers the retrieval ring 52 to collect the floating debris inside the outer cylinder 51.

[0072] Then the lifting motor 524 reverses, which drives the hanging plate 523 to rise. When the hanging plate 523 rises, it drives the salvage ring 52 to rise. At this time, the wastewater drips down through the through hole on the salvage ring 52. Then the salvage ring 52 rises until the inner cavity of the salvage ring 52 is in contact with the bottom of the sweeping plate 68. At this time, the support rods 67 on both sides rotate along the axis of the rotating plate 61. When the support rods 67 on both sides rotate, they drive the sweeping plate 68 to sweep the impurities on the salvage ring 52 into the collection box 520 for unified collection.

[0073] When sorting and discharging excrement, feed, and drug particles in wastewater, since the excrement, feed, and drug particles are of different sizes, the adjusting rod 39 is rotated. The adjusting rod 39 drives the drive wheel 38 to rotate. When the drive wheel 38 rotates, it meshes with the adjusting plate 33, thereby driving the adjusting plate 33 to rotate. Since the adjusting plate 33 is rotatably connected to the outside of the rotating ring 34, the size of the filter holes on the lifting plate 32 is adjusted when the adjusting plate 33 rotates, so as to realize the sorting and recycling of excrement, drug particles, and other particles of different sizes in the wastewater. When recycling wastewater, the lifting rod 395 is rotated. The lifting rod 395 drives the rack plate 393 to descend through the lifting wheel 396. The rack plate 393 drives the lifting plate 32 to adjust the height, so that the fish on the lifting plate 32 can rise and fall synchronously with the water level line during wastewater treatment, and wastewater recycling can be completed without the need to catch the fish separately.

[0074] When particulate matter in the wastewater clogs the filter holes on the regulating plate 33 and the lifting plate 32, the pull rod 35 is pulled upwards. The pull rod 35 drives the unblocking rod 37 to rise through the unblocking plate 36 to unblock the filter holes, thus preventing the particulate matter in the wastewater from clogging and preventing the particulate matter from falling and being recycled. Finally, the water pump is turned on so that the water exchange pipe 7 draws the wastewater inside the water storage frame 31 into the purification tank 8. The purification tank 8 purifies the wastewater from seawater aquaculture.

[0075] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.

4. A method of using a marine aquaculture wastewater treatment device, comprising the marine aquaculture wastewater treatment device as described in claim 2, characterized in that, The method of use includes the following steps: S1: Wastewater surface treatment: Turn on the salvage motor (63). The salvage motor (63) drives the gear (64) on one side to rotate through the pulley (65) and belt (66). When the gear (64) rotates, it meshes with the inner side of the rotating plate (61) to drive the rotating plate (61) to rotate. When the rotating plate (61) rotates, it drives the paddle (59) to rotate, thereby agitating the wastewater surface and causing the impurities on the wastewater surface to pass through the rectangular groove and be located inside the outer cylinder (51). Then, the impurities are salvaged and collected by the salvage ring (52). S2: Wastewater sorting and recycling: The filter holes in the middle of the lifting plate (32) filter and collect excrement, feed, and drug particles in the marine aquaculture wastewater. By rotating the adjusting rod (39), the adjusting rod (39) drives the drive wheel (38) to rotate. When the drive wheel (38) rotates, it meshes with the adjusting plate (33), thereby driving the adjusting plate (33) to rotate. Since the adjusting plate (33) is rotatably connected to the outer side of the rotating ring (34), the size of the filter holes on the lifting plate (32) is adjusted when the adjusting plate (33) rotates, so as to facilitate the filtration of particles of different sizes. To recycle, the lifting rod (395) is rotated, and the lifting rod (395) drives the rack plate (393) to descend through the lifting wheel (396). The rack plate (393) drives the lifting plate (32) to adjust its height so that the fish on the lifting plate (32) can rise and fall synchronously with the water level line when treating wastewater. Pull the lever (35) upward, and the lever (35) drives the unblocking rod (37) to rise through the unblocking plate (36) to unblock the blocked filter holes, thus avoiding the blockage of particles in the wastewater, which would prevent the particles from falling and being recycled. S3: Wastewater purification: By turning on the water pump in the water exchange pipe (7), the water exchange pipe (7) draws the wastewater inside the water storage box (31) into the purification box (8). The purification box (8) purifies the wastewater from seawater aquaculture so that the wastewater can be reused after treatment.
