Description

Technical Field

[0001] The invention relates to the technical field of circulating water aquaculture, and in particular to a circulating water aquaculture pond and aquaculture technology thereof. Background Art

[0002] Recirculating aquaculture technology is a new type of aquaculture model that integrates advanced technologies from multiple disciplines such as environmental engineering, civil engineering, modern biology, and electronic information. This technology uses a series of water treatment units, such as physical filtration, biological filtration, disinfection, and oxygenation, to purify the wastewater generated in the aquaculture pond and recycle it for reuse to remove harmful pollutants such as residual bait and feces, ammonia nitrogen, and nitrite nitrogen, providing a stable, reliable, comfortable, and high-quality living environment for aquaculture organisms. It not only solves the problem of low water resource utilization, but also provides favorable conditions for high-density aquaculture.

[0003] In order to facilitate the cleaning of harmful pollutants such as residual bait, feces, ammonia nitrogen, nitrite nitrogen, etc. deposited in the breeding pond, the bottom of the breeding pond is usually set to a conical structure, so that the waste in the breeding pond can quickly gather to the center end of the bottom of the conical structure, and then can be discharged from the sewage outlet; For details, please refer to the figure of a coho salmon circulating water breeding pond disclosed in the patent document with announcement number CN205305741U;

[0004] However, this type of breeding pond also has certain disadvantages. Since some waste materials are bonded to form a large volume of waste materials, when the water outlet and the sewage outlet are directly connected to the bottom of the conical structure, not only will the water outlet and the sewage outlet be blocked, but they will also adhere to the inner wall of the pipe connected to the water outlet and the sewage outlet, making it difficult to clean. When dead fish appear in the breeding pond, the fish can easily block the bottom opening of the conical structure, thereby affecting the normal operation of the breeding pond.

[0005] At present, a filter cartridge with a certain height is usually arranged at the bottom open end of the conical structure, and water outlet holes are evenly opened on the filter cartridge. The water in the breeding pond can enter the filter cartridge through the water outlet holes and then be discharged. However, after a long period of operation, a large amount of mutually bonded waste will be deposited on the periphery of the filter cartridge. These wastes are large in volume and cannot be discharged through the water outlet holes, and will cause the water outlet holes to be blocked. Manual cleaning is still required at regular intervals, which is very troublesome. Summary of the invention

Manual cleaning is not required at regular intervals, and the operation is more convenient, which is conducive to maintaining the normal operation of circulating aquaculture.

[0035] When the sealing cover of the present invention is in the initial position, the annular scraper is just at the top of the filter cartridge. As the sealing cover descends, the sealing cover can synchronously drive the annular scraper to descend. During the descending process of the annular scraper, part of the waste material adhering to the surface of the filter cartridge can be scraped off, so that the waste material is cleaned more fully.

[0036] When the annular scraper of the present invention moves downward along the outer wall of the filter cartridge, the driving part drives each cleaning frame to move in a direction away from the axis, and the cleaning frame drives the cleaning rod to be inserted into the water outlet hole, thereby discharging the waste material blocked in the water outlet hole, so that the annular scraper can synchronously scrape off the waste material;

[0037] In the present invention, when the sealing cover presses the annular plate in a descending state, due to the interference of the sealing cover, the annular plate cannot be directly driven to flip and discharge materials. Therefore, the adjustment part is first used to drive the racks on both sides to move away from each other, so that they are in a dislocated and separated state with the gear when descending. When the gear descends to the limit position, the adjustment part drives the racks on both sides to reset. As the sealing cover rises, the elastic module can synchronously drive the annular plate to rise. During the rising process, the gear can engage with the rack to drive the annular plate to deflect a certain angle, thereby automatically discharging the waste on its surface.

DETAILED DESCRIPTION

[0049] 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.

[0050] Example 1

[0051] See also Figure 1 As shown, the present invention is a circulating water aquaculture pond, comprising a pond body 1; specifically, the pond body 1 is a cylindrical structure, wherein a conical cylinder 106 is provided at the bottom of the pond body 1;

[0052] A water inlet pipe 103 is provided on one side of the pond body 1 for inputting purified aquaculture water into the pond body 1 .

[0053] See also Figure 1-Figure 3 A through groove 107 is provided at the bottom of the conical cylinder 106, and an annular plate 401 is slidably embedded in the through groove 107, and a filter cartridge 3 is arranged at the central end of the annular plate 401; specifically, the through groove 107 is a circular groove, and the outer edge surface of the annular plate 401 is slidably fitted with the groove wall of the through groove 107, and the inner edge surface of the annular plate 401 is slidably fitted with the outer wall of the filter cartridge 3.

[0054] See also Figure 7 The filter cartridge 3 is provided with a plurality of rows of water discharge holes 302 in a circumferential array, and each row of water discharge holes 302 is provided with a plurality of groups arranged at equal intervals; in this embodiment, the water in the pool body 1 first enters the filter cartridge 3 through the water discharge holes 302, and then can be discharged from the filter cartridge 3;

[0055] Among them, the bonded waste materials gather at the bottom of the conical cylinder 106 and are located on the annular plate 401. In order to discharge these bonded large-volume waste materials, in this embodiment, a sealing cover 201 is also slidably sleeved on the filter cylinder 3; it should be noted that the sealing cover 201 is an overall cylindrical structure, and its diameter is equal to the outer diameter of the annular plate 401, and its bottom is set as an open structure, and its top is set as a sealing structure.

[0056] The tank body 1 is also provided with a lifting module, which is used to drive the sealing cover 201 and the annular plate 401 to rise and fall along the axial end of the tank body 1;

[0057] It can be explained that, in the initial state, the sealing cover 201 and the annular plate 401 are in a separated state, so the water in the pool body 1 can enter the filter cartridge 3 along the water outlet 302 through the gap. When a large amount of adhesive waste is deposited on the annular plate 401, the sealing cover 201 is driven to descend by the lifting module so that the sealing cover 201 is covered on the annular plate 401, thereby isolating the waste deposited on the annular plate 401, and the water in the pool body 1 cannot enter the sealing cover 201. Then, the sealing cover 201 and the annular plate 401 are driven to continue to descend by the lifting module until the annular plate 401 is lowered to the bottom of the conical cylinder 106 and separated from the through groove 107. At this time, the waste on the annular plate 401 can be removed. After the removal is completed, the annular plate 401 and the sealing cover 201 are driven to reset by the lifting module.

[0058] In this embodiment, not only can the large-volume waste materials that are bonded be filtered on the outside of the filter cartridge 3 to prevent these waste materials from passing through the water outlet hole 302 and entering the filter cartridge 3 to cause blockage of the water outlet or sewage discharge channel, but the sealing cover 201 cooperates with the annular plate 401 to discharge the waste materials deposited on the periphery of the filter cartridge 3, thereby preventing the water outlet hole 302 from being blocked. There is no need for manual cleaning at a fixed time, and the operation is more convenient, which is conducive to maintaining the normal operation of the circulating aquaculture.

[0059] In addition, it should be noted that in this embodiment, a pressure detection device can be set in the water outlet or sewage discharge channel to perform pressure detection to determine whether a large amount of adhesive waste is deposited on the periphery of the filter cartridge 3. A monitor can also be set in the sealing cover 201 to directly detect the waste deposited on the annular plate 401, thereby determining whether cleaning is required.

[0060] Example 2

[0061] Based on Example 1, please refer to Figure 4-Figure 6 The bottom of the filter cartridge 3 is plugged with the drain terminal 4, and the two sides of the drain terminal 4 are fixed to the annular plate 401 through the L-shaped support plate 404, wherein the bottom end of the drain terminal 4 is connected to the drain pipe 104 through the telescopic tube 108; in the normal drainage state, the drain terminal 4 is embedded in the bottom of the filter cartridge 3, so that the water entering the filter cartridge 3 through the water outlet 302 can be discharged in sequence through the drain terminal 4, the telescopic tube 108 and the drain pipe 104, and finally after sedimentation and filtration, it is circulated and transported to the pool body 1 through the water inlet pipe 103, so as to achieve the effect of circulating aquaculture;

[0062] In this embodiment, when the lifting module drives the annular plate 401 to descend, the annular plate 401 can synchronously drive the drainage terminal 4 to separate from the filter cartridge 3 through the L-shaped support plate 404. Since the sealing cover 201 at this time isolates the water in the pool body 1 from continuing to enter the filter cartridge 3 through the water outlet 302, even if the drainage terminal 4 is separated from the filter cartridge 3, the filter cartridge 3 will not continue to drain water.

[0063] See also Figure 3 An annular scraper 202 is also fixedly arranged in the sealing cover 201, and the annular scraper 202 is slidably sleeved on the filter cartridge 3; specifically, when the sealing cover 201 is in the initial position, the annular scraper 202 is just at the top of the filter cartridge 3, and as the sealing cover 201 descends, the sealing cover 201 can synchronously drive the annular scraper 202 to descend, and during the descending process of the annular scraper 202, part of the waste adhering to the surface of the filter cartridge 3 can be scraped off, so that the waste cleaning is more thorough.

[0064] In this embodiment, please refer to Figure 1-Figure 3The lifting module includes a mounting frame 101 fixedly arranged on the pool body 1, and a lifting cylinder 2 is fixedly arranged on the mounting frame 101, and a driving end of the lifting cylinder 2 is fixed to the top of the sealing cover 201, wherein the annular plate 401 is connected to an elastic module arranged at the bottom of the conical cylinder 106; specifically, when it is necessary to drive the sealing cover 201 to descend, starting the lifting cylinder 2 can drive the sealing cover 201 to move, and when the sealing cover 201 descends to contact with the annular plate 401, as the sealing cover 201 continues to descend, the sealing cover 201 can press the annular plate 401 to synchronously descend, and at this time, the elastic module contracts to generate elastic force, so that when the lifting cylinder 2 drives the sealing cover 201 to rise, the elastic module can synchronously drive the annular plate 401 to rise.

[0065] It should be noted that the lifting cylinder 2 of the present embodiment can also be replaced by a hydraulic cylinder, an electric cylinder or a screw-nut transmission mechanism to achieve driving the sealing cover 201 to lift and lower, and this is not limited to this.

[0066] In addition, at least one set of support rods 301 is fixedly arranged on the top of the filter cartridge 3 in this embodiment, and the other end of the support rods 301 slides through the sealing cover 201 and is fixed to the mounting frame 101, thereby supporting the filter cartridge 3.

[0067] As a further solution of this embodiment, please refer to Figure 5-Figure 7 In order to discharge some of the waste materials blocked in the water outlet hole 302, a plurality of cleaning racks 6 corresponding to the water outlet holes 302 in each column are arranged in a circumferential array in the filter cartridge 3, and a plurality of cleaning rods 601 corresponding to the water outlet holes 302 are fixedly arranged on one side of each cleaning rack 6 away from the axis of the filter cartridge 3, wherein a driving unit is arranged in the filter cartridge 3, and the driving unit is used to drive each cleaning rack 6 to move toward or away from the axis; it can be explained that when the annular scraper 202 moves downward along the outer wall of the filter cartridge 3, each cleaning rack 6 is driven by the driving unit to move in the direction away from the axis, and the cleaning rack 6 drives the cleaning rod 601 to be inserted into the water outlet hole 302, thereby discharging the waste materials blocked in the water outlet hole 302, so that the annular scraper 202 can synchronously scrape off this part of the waste materials.

[0068] In this embodiment, the driving part includes a plurality of groups of first telescopic cylinders 602 fixedly arranged on the inner wall of the filter cartridge 3 in a circumferential direction. The first telescopic cylinders 602 are axially arranged at both ends of the filter cartridge 3 and correspond to the cleaning racks 6 one by one. The telescopic ends of the first telescopic cylinders 602 are respectively fixed to the cleaning racks 6 on the corresponding side, and the first springs 603 are arranged on the telescopic ends. The top of each cleaning rack 6 close to the axial direction is set as an inclined surface 604, and the top of the filter cartridge 3 is correspondingly arranged with a conical end 605, the outer conical surface of the conical end 605 is slidably fitted with the inclined surface 604, and a lifting rod is fixedly arranged on the conical end 605. 303, the lifting rod 303 slides through the top wall of the filter cartridge 3 and is fixed to the sealing cover 201; it can be explained that when the sealing cover 201 descends, the lifting rod 303 can be synchronously driven to descend. In the process of the lifting rod 303 driving the conical end 605 to descend, the outer cone surface of the conical end 605 abuts against the inclined surface 604, which can drive each cleaning frame 6 to move in the direction away from the axial end. During the movement, the cleaning frame 6 drives the first telescopic cylinder 602 to contract to compress the first spring 603 to generate elastic force. Later, when the lifting rod 303 rises, the first spring 603 can synchronously drive each cleaning frame 6 to reset.

[0069] Further, when the annular plate 401 is inserted into the through groove 107, in order to support and limit the annular plate 401, in this embodiment, refer to Figure 3-Figure 4 as well as Figure 8 The through groove 107 is provided with a plurality of groups of limiting grooves 609 in a circumferential direction, and a groove 402 corresponding to the limiting groove 609 is provided in a circumferential direction on the annular plate 401, and a wedge-shaped seat 403 is slidably arranged in the groove 402, and the inclined surface of each wedge-shaped seat 403 is located on the side away from the axis, and a sliding groove 606 is provided on the groove wall of the groove 402 close to the axis direction, and a second spring 607 is fixedly arranged on the groove wall of the sliding groove 606, and the other end of the second spring 607 is fixed to the guide rod 608, and the guide rod 608 and the wedge seat 403 Fixed; It can be explained that when the annular plate 401 is in a state of being embedded in the through groove 107, based on the setting of the second spring 607, the wedge seat 403 is embedded in the limiting groove 609, which plays a role of clamping, so that the annular plate 401 cannot move downward. When the sealing cover 201 moves toward the annular plate 401, as the bottom edge of the sealing cover 201 abuts against the inclined surface of the wedge seat 403, the wedge seat 403 can be driven to shrink toward the groove 402, so as to continue to push the annular plate 401 to move downward.

[0070] Correspondingly, when the annular plate 401 moves from the bottom of the conical cylinder 106 to the through groove 107 , the wedge-shaped seat 403 can be driven to return to the limiting groove 609 under the elastic force of the second spring 607 .

[0071] See also Figure 1-Figure 2 as well as Figure 4-Figure 6The two ends of the mounting frame 101 are respectively fixed with the support frame 102, the elastic module includes a support shaft 405 fixedly arranged on the L-shaped support plate 404, the support shaft 405 is located on the side away from the axis, and a support seat 407 is rotatably arranged on the support shaft 405. One side of the support seat 407 is fixed to a movable seat 508 through a connecting rod, and the movable seat 508 is slidably sleeved on the limit rod 502, and the limit rod 502 is fixed on the limit frame 507. The limit frame 507 is fixed to the support frame 102 through a connecting plate 109, wherein the limit rod 502 is provided with The third spring 503; specifically, one end of the third spring 503 is fixed to the limit frame 507, and the other end is fixed to the movable seat 508; it can be explained that when the sealing cover 201 presses the annular plate 401 to move toward the bottom of the conical cylinder 106, the annular plate 401 drives the movable seat 508 to slide on the limit rod 502 through the L-shaped support plate 404, the support shaft 405 and the support 407, so as to compress the third spring 503 and generate elastic force. When the sealing cover 201 rises, the third spring 503 can drive the various components to reset synchronously.

[0072] Furthermore, when the annular plate 401 descends to the bottom of the conical cylinder 106, in order to facilitate the discharge of the waste material on its surface, in the present embodiment, a gear 408 is fixedly arranged on the support shaft 405, wherein a rack 504 is arranged on the limit frame 507, and the racks 504 on both sides are connected to the adjusting part that drives them to move closer or farther away from each other; it can be explained that when the sealing cover 201 presses the annular plate 401 in the descending state, due to the interference of the sealing cover 201, the annular plate 401 cannot be directly driven to flip and discharge materials, so the racks 504 on both sides are first driven to move away from each other by the adjusting part, so that they are in a dislocated and separated state with the gear 408 when descending, and when the gear 408 descends to the limit position, the adjusting part drives the racks 504 on both sides to reset, and as the sealing cover 201 rises, the elastic module can synchronously drive the annular plate 401 to rise, and during the rising process, the gear 408 can mesh with the rack 504 to drive the annular plate 401 to deflect a certain angle, thereby discharging the waste material on its surface.

[0073] In addition, a torsion spring 406 is provided on the support shaft 405. When the gear 408 loses meshing with the rack 504, the torsion spring 406 can drive the support shaft 405 and the annular plate 401 to return to their original position.

[0074] For details, please refer to Figure 4-Figure 6The adjusting part includes an L-shaped bracket 409 fixedly arranged at the end of the support shaft 405, and a guide wheel 410 is rotatably arranged at the end of the L-shaped bracket 409. A second telescopic cylinder 505 is also fixedly arranged on the end of the connecting plate 109 away from the support frame 102. The telescopic end of the second telescopic cylinder 505 is fixed to the guide frame 5, and the rack 504 is fixedly arranged on one side of the guide frame 5. The ends of the guide frames 5 on both sides away from the limit frame 507 are fixedly arranged with tilting frames 501, and the tilting frames 501 on both sides are tilted in the direction away from each other, wherein a fourth spring 506 is also arranged on the telescopic end of the second telescopic cylinder 505; it can be explained that as the sealing cover 20 The annular plate 401 is pressed to descend, and the annular plate 401 can synchronously drive the guide wheel 410 to descend. During the process of the guide wheel 410 descending, it first rolls and abuts against the tilting frame 501, and drives the guide frames 5 on both sides to move away from each other through the tilting frame 501, so that the rack 504 and the gear 408 are misaligned. At this time, the fourth spring 506 contracts to generate elastic force. When the guide wheel 410 descends to the bottom of the guide frame 5, the fourth spring 506 drives the tilting frame 501 to reset. Therefore, when the guide wheel 410 is driven to rise, the guide wheel 410 is located on the side of the guide frame 5 away from the axis. The descending and ascending process of the guide wheel 410 in this embodiment can be referred to Fig. 9 .
