Description

Technical Field

[0001] This utility model relates to the field of marine aquaculture technology, specifically a marine recirculating aquaculture device. Background Technology

[0002] Aquaculture is a production activity involving the breeding, cultivation, and harvesting of aquatic plants and animals under human control. It generally includes the entire process from seedling to aquatic product under artificial feeding and management. In a broader sense, it can also include the enhancement of aquatic resources. Aquaculture can be carried out in various ways, such as extensive farming, intensive farming, and high-density intensive farming. Extensive aquaculture involves stocking seedlings in small to medium-sized natural waters and raising aquatic products entirely based on natural feed, such as fish farming in lakes and reservoirs and shellfish farming in shallow seas. Intensive aquaculture involves raising aquatic products in smaller bodies of water using feeding and fertilization methods, such as pond fish farming, net cage fish farming, and enclosure aquaculture. Intensive aquaculture often requires pumping natural seawater into the aquaculture ponds, and the seawater in the aquaculture ponds needs to be replaced regularly. Therefore, regular water changes require a large amount of seawater, and wastewater discharge must also be environmentally friendly. The whole process is time-consuming, labor-intensive, and economically costly. Some aquaculture ponds use sand filtration equipment to recycle seawater from each aquaculture pond. However, impurities in the seawater, as well as excrement and feed waste from the aquaculture process, accumulate rapidly during the circulation of the seawater through each aquaculture pond, resulting in poor water quality when it reaches the final aquaculture pond. In addition, large particles of impurities in the water concentrate in the sand filtration equipment, causing rapid blockage and requiring frequent backwashing. Utility Model Content

[0003] The purpose of this invention is to provide a seawater recirculating aquaculture device that allows for dual-interval filtration of seawater during a single cycle while sharing the same water in multiple pools. This avoids the poor water quality in the last four pools and facilitates the removal and cleaning of the seawater after preliminary filtration through the filter chamber. It also prevents large particles of impurities from being concentrated in the sand filter tank and causing rapid blockage.

[0004] To achieve the above objectives, a seawater recirculating aquaculture system is provided, comprising an aquaculture pond. The aquaculture pond is constructed by a cross-shaped symmetrical arrangement of pond number one, pond number two, pond number three, and pond number four. Pond number one is located on the front right side of the aquaculture pond. Ponds number two, three, and four are arranged counter-clockwise from a top-down view. Sponge sleeves are mounted on the top rear end of opposite sides of ponds one and four. The bottom of each sponge sleeve is fixedly connected to the aquaculture pond. A first pump is fitted and fixed inside each sponge sleeve. Water guide pipes are connected and fixed at both ends of the first pump. The lower ends of the opposite sides of the water guide pipes extend into the lower inner part of the aquaculture pond. A sand filter tank is mounted at the center of opposite sides of ponds one and four. A drain pipe is fixedly connected to the center of the bottom of the sand filter tank. The right bottom end of the drain pipe is fixedly connected to pond number one. An inlet pipe is fixedly connected to the center of the top of the sand filter tank. A second pump is fixedly connected to the left end of the inlet pipe. A water pump is fixedly connected to the center of the left side of the second pump. The bottom left end of the water pump extends into the lower inner part of the fourth pool. Each of the two pools has an opening at the center of its opposite side. A frame is fixedly connected to the opposite side of each opening. A gate is slidably engaged at the top of each frame. A sealing strip is fixedly connected to the opposite side of each frame. A filter chamber is mounted on the opposite side of the sealing strip. Flexible connecting frames are provided on both sides of the filter chamber. The sealing strip is inserted into the inner wall of the flexible connecting frame and engaged. By connecting water pipes between adjacent pools and using filter chambers and sand filters at intervals, the injected seawater is filtered and circulated. While sharing water across multiple pools, the seawater in each cycle undergoes double-interval filtration. This avoids the water quality in the fourth pool being poor and facilitates the initial filtration of the seawater through the filter chambers before removal and cleaning. It also prevents large particles from concentrating and quickly clogging the sand filter.

[0005] According to the aforementioned seawater recirculating aquaculture device, the top of the filter chamber is symmetrically fitted with frosted pads. This allows the filter chamber to be easily removed, replaced, and cleaned by pressing and pushing it back.

[0006] According to the aforementioned seawater recirculating aquaculture device, each of the gates has a handle fixedly connected to the center of its top. This facilitates opening and closing the gates to clean and replace the filter chamber.

[0007] According to the aforementioned seawater recirculating aquaculture device, the outer side of the sand filter tank is symmetrically fitted with positioning hoops, and the left and right sides of the positioning hoops are symmetrically fixed with mounting brackets. The opposite sides of the mounting brackets are respectively fixedly connected to pool one and pool two. This ensures the stable installation of the sand filter tank.

[0008] According to the aforementioned seawater recirculating aquaculture system, a coarse filter cylinder is fixedly connected to the outer side of the bottom end of the pumping pipe. This isolates excrement and feed waste, preventing them from rapidly clogging the sand filter tank.

[0009] According to the aforementioned seawater recirculating aquaculture system, a groove is provided at the top front right end of the No. 1 pool, and a pipe for injecting seawater is embedded in the groove. This facilitates the construction of the water supply path and avoids sharp angles.

[0010] According to the aforementioned seawater recirculating aquaculture device, sealing gaskets are fixedly connected to the outer sides of each gate, and these sealing gaskets are pressed and fitted against the frame. This improves the leak-proof strength of the third and fourth tanks after partitioning.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, water pipes are installed between adjacent aquaculture ponds, and filter chambers and sand filters are used at intervals to filter and circulate the injected seawater. While the water is shared by multiple ponds, the seawater in each cycle is filtered twice at intervals. This avoids the poor water quality in the last four ponds and makes it easier to remove and clean the seawater after preliminary filtration through the filter chambers. It also prevents large particles of impurities from being concentrated in the sand filters and causing blockages.

[0013] Additional aspects and advantages of this invention 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 the invention. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a seawater recirculating aquaculture device, including an aquaculture pond 1. The aquaculture pond 1 is composed of four ponds arranged in a cross-shaped symmetrical configuration: pond 1 is located on the front right side of aquaculture pond 1, and the remaining ponds 2, 3, and 4 are arranged counterclockwise from a top view. A groove 20 is provided at the top front right end of the top of pond 1, and a pipe for injecting seawater is embedded in the groove 20. Sponge sleeves 2 are provided on the top of the rear end of ponds 1 and 4 on opposite sides. The bottom of each seat 2 is fixedly connected to the aquaculture pond 1. A first pump 3 is fitted and fixedly installed inside each sponge seat 2. Water guide pipes 4 are fixedly connected to both the front and rear ends of the first pump 3. The lower ends of the opposite sides of the water guide pipes 4 extend into the lower inner part of the aquaculture pond 1. A sand filter tank 5 is installed at the center of the opposite side of ponds 1 and 4. A drain pipe 6 is fixedly connected to the center of the bottom of the sand filter tank 5. The right end of the bottom of the drain pipe 6 is fixedly connected to pond 1. An inlet pipe 7 is fixedly connected to the center of the top of the sand filter tank 5. A second pump 8 is fixedly connected to the left end. A water pumping pipe 9 is fixedly connected to the center of the left side of the second pump 8. The bottom left end of the water pumping pipe 9 extends into the lower inner part of pool number four. A coarse filter cylinder 19 is fixedly connected to the outer side of the bottom end of the water pumping pipe 9. An opening is provided at the center of the opposite side of pool number two and pool number three. A frame 10 is fixedly connected to the opposite side of the opening. A gate 11 is slidably engaged on the top of the frame 10. A sealing strip 12 is fixedly connected to the opposite side of the frame 10. A support is installed on the opposite side of the sealing strip 12. There is a filter chamber 13, and there are elastic docking frames 14 on both the left and right sides of the filter chamber 13. The sealing strips 12 are inserted into the inner wall of the elastic docking frame 14 and locked in place. The top of the filter chamber 13 is symmetrically fixed with frosted pads 15. While using one water for multiple pools, the seawater of a single circulation is filtered in a double interval. This avoids the poor water quality of the last fourth pool and makes it easy to remove and clean the seawater after the initial filtration through the filter chamber. It also prevents large particles of impurities from being concentrated and circulating into the sand filter tank, which can cause blockage quickly.

[0022] A handle 16 is fixedly connected to the top center of each gate 11, and a sealing gasket is fixedly connected to the outer side of each gate 11. The sealing gaskets are pressed and fitted against the frame 10 to improve the sealing and isolation strength of the gate to the opening and prevent water leakage when replacing or cleaning the filter chamber.

[0023] The outer side of the sand filter tank 5 is symmetrically fitted with positioning hoops 17, and the left and right sides of the positioning hoops 17 are symmetrically fixed with mounting seats 18. The opposite side of the mounting seats 18 is fixedly connected to the No. 1 pool and the No. 2 pool respectively to maintain the vertical and stable erection of the sand filter tank.

[0024] Working principle: In this utility model, by connecting and installing water pipes 4 between adjacent ponds of aquaculture pond 1, and using filter chambers 13 and sand filter tanks 5 at intervals, the injected seawater is filtered and circulated. While sharing water among multiple ponds, the seawater in each cycle is filtered twice at intervals. This avoids the problem of poor water quality in the last four ponds and makes it easier to remove and clean the seawater after preliminary filtration through the filter chambers 13. It also avoids the problem of large particles of impurities being concentrated in the sand filter tank 5 and quickly causing blockage, requiring frequent disassembly and backwashing. The plug-in filter chambers 13 complete the initial screening of impurities and provide a replacement and cleaning method that is superior to that of the sand filter tank 5, thus reducing the difficulty of cleaning.

[0025] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
