Description

Technical Field

[0001] This utility model relates to the field of aquaculture system technology, and in particular to a recirculating aquaculture system. Background Technology

[0002] Recirculating aquaculture systems (RAS) are a highly efficient and environmentally friendly aquaculture technology that achieves water quality control, ecological protection, improved aquaculture efficiency, biological filtration, automation, economic efficiency, and sustainable development. It has become an important direction for modern aquaculture.

[0003] Existing recirculating aquaculture systems include a rearing pond, a return water pipe, a supply water pipe, and a storage tank. Water is stored in the storage tank, and water from the storage tank is sent to the rearing pond through the supply water pipe. Water from the rearing pond then returns to the storage tank through the return water pipe, thus circulating the water. However, because the rearing ponds in existing recirculating aquaculture systems are located in an open environment, external debris such as leaves can easily fall into the rearing ponds and float on the water surface, which can easily clog the return water pipe and affect water circulation. Utility Model Content

[0004] To address the drawback of existing recirculating aquaculture systems where the return water pipe is prone to clogging, this invention proposes a recirculating aquaculture system that prevents the return water pipe from becoming clogged.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A recirculating aquaculture system includes an aquaculture pond, a water storage pond, a pumping mechanism, and a return water pipe. The opening of the water storage pond is lower than the opening of the aquaculture pond. The pumping mechanism pumps water from the water storage pond into the aquaculture pond. One end of the return water pipe is provided with an inlet and is located in the aquaculture pond. The other end of the return water pipe is provided with an outlet and is located in the water storage pond. The inlet is higher than the outlet.

[0007] The aquaculture system also includes a filtration mechanism, which includes a base plate, a support plate, a tube, a filter screen, and a handle. The base plate is fixedly connected to the outer side of the upper end of the tube, the tube is inserted into the water inlet, the filter screen is fixedly connected to the upper side of the base plate around the tube, the handle is installed on the upper side of the filter screen, and the support plate is fixedly connected to the lower side of the base plate and extends outward.

[0008] With the above settings, firstly, the filtration mechanism can filter impurities, prevent impurities from clogging the return water pipe, and facilitate the cleaning of impurities; secondly, the return water relies on gravity, saving energy.

[0009] Furthermore, the filtration mechanism also includes a top plate, with the upper side of the filter screen fixedly connected to the lower side of the top plate along its edge, and a handle fixedly connected to the upper side of the top plate.

[0010] With the above setup, the handle is fixedly connected to the filter screen via the top plate.

[0011] Furthermore, the aquaculture system also includes a sliding sleeve, an annular baffle, and an elastic element. The sliding sleeve is located below the bottom plate and is slidably connected to the return water pipe. The annular baffle is arranged around the sliding sleeve and is fixedly connected to the sliding sleeve. The elastic element applies an upward elastic force, so that the upper part of the annular baffle fits against the lower part of the support plate.

[0012] The above settings prevent the water inlet from becoming clogged when pouring out impurities.

[0013] Furthermore, the aquaculture system also includes a retaining ring that is locked onto the return water pipe. The elastic element is a spring that is fitted onto the return water pipe. The upper end of the spring is connected to the sliding sleeve, and the lower end of the spring is connected to the retaining ring.

[0014] Furthermore, the aquaculture system also includes a biofilter, through which a pumping mechanism delivers water from the storage tank into the aquaculture pond.

[0015] The above settings enhance the purification capacity of the aquaculture system.

[0016] Furthermore, the opening of the biological filter is higher than the opening of the aquaculture pond. The pumping mechanism includes a lift pump, a first pipe section, and a second pipe section. The lift pump is installed in the water storage tank. The lower end of the first pipe section is connected to the lift pump, and the upper end of the first pipe section extends above the biological filter. One end of the second pipe section is installed on the upper side of the biological filter, and the other end of the second pipe section extends above the aquaculture pond.

[0017] Furthermore, the aquaculture ponds are equipped with multiple return water pipes, including a main water pipe and multiple branch water pipes. The branch water pipes run through the bottom of the aquaculture ponds, with the water inlet located at the upper end of the branch water pipe, the lower end of the branch water pipe connected to the main water pipe, and the water outlet located at one end of the main water pipe.

[0023] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0024] like Figures 1 to 5A recirculating aquaculture system includes an aquaculture pond 3, a water storage pond 4, a pumping mechanism, and a return water pipe 6. The opening of the water storage pond 4 is lower than the opening of the aquaculture pond 3. The pumping mechanism pumps water from the water storage pond 4 into the aquaculture pond 3. One end of the return water pipe 6 is provided with an inlet 7 and is located in the aquaculture pond 3. The other end of the return water pipe 6 is provided with an outlet 8 and is located in the water storage pond 4. The inlet 7 is higher than the outlet 8.

[0025] The aquaculture system also includes a filtration mechanism 9, which includes a base plate 91, a support plate 92, a tube 93, a filter screen 94, and a handle 95. The base plate 91 is fixedly connected to the outer side of the upper end of the tube 93. The tube 93 is inserted into the water inlet 7. The filter screen 94 is fixedly connected to the upper side of the base plate 91 around the tube 93. The handle 95 is installed on the upper side of the filter screen 94. The support plate 92 is fixedly connected to the lower part of the base plate 91 and extends outward.

[0026] With the above settings, firstly, the filter mechanism 9 can filter impurities, prevent impurities from clogging the return water pipe 6, and facilitate the cleaning of impurities; secondly, the return water relies on gravity, saving energy.

[0027] During normal operation of the aquaculture system, water is stored in the reservoir 4, and fish are raised in the aquaculture pond 3. The pumping mechanism pumps water into the aquaculture pond 3. One end of the return pipe 6 is located in the aquaculture pond 3 and extends vertically. The inlet 7 faces upward and is close to the opening of the aquaculture pond 3. After the pumping mechanism pumps water into the aquaculture pond 3, the water volume in the aquaculture pond 3 increases and the water level rises. The water in the aquaculture pond 3 passes through the filtration mechanism 9, the inlet 7, the return pipe 6, and the outlet 8 and is discharged into the reservoir 4, allowing the water to circulate. Since the inlet 7 is higher than the outlet 8, the water in the aquaculture pond 3 can return to the reservoir 4 under the action of gravity, achieving an energy-saving effect.

[0028] The filtration mechanism 9 can filter impurities 20 on the water surface in the water storage tank 4, preventing impurities from clogging the inlet 7 of the return water pipe 6; for example Figure 4 When the filter mechanism 9 is installed in the inlet 7, both the base plate 91 and the support plate 92 are annular. The base plate 91 is horizontally fixed to the outer side of the upper end of the insertion tube 93, and the upper side of the base plate 91 is flush with the water surface. The support plate 92 is horizontally fixed to the lower part of the base plate 91, and the support plate 92 is submerged below the water surface. The outer edge of the support plate 92 extends outward, and the outer diameter of the support plate 92 is larger than the outer diameter of the base plate 91. The filter screen 94 is basically cylindrical, and the lower side of the filter screen 94 is fixedly connected to the edge of the base plate 91. The filter screen 94 is made of metal and has a certain rigidity. After the water in the aquaculture pond 3 passes through the filter screen 94 and the upper side of the base plate 91, it flows into the return water pipe 6 through the insertion tube 93. Impurities are isolated on the outside of the filter screen 94. When it is necessary to clean the impurities, the filter mechanism 9 is lifted by the handle 95, and the insertion tube 93 is pulled out from the outlet 8. Figure 5The tray 92 holds the impurities and carries them away from the water surface, making it easy to empty the impurities. After emptying the impurities, the filter mechanism 9 is reinstalled back into the inlet 7.

[0029] As one implementation, the filter mechanism 9 also includes a top plate 96, with the upper side of the filter screen 94 fixedly connected to the lower side of the top plate 96 along its edge, and the handle 95 fixedly connected to the upper side of the top plate 96.

[0030] With the above configuration, the handle 95 is fixedly connected to the filter screen 94 via the top plate 96.

[0031] The top plate 96 of this application is circular, and its outer diameter is the same as that of the bottom plate 91. The filter screen 94 is welded to the top plate 96 on the upper side. The top plate 96 supports the filter screen 94 and prevents the filter screen 94 from deforming. The handle 95 is welded to the upper side of the top plate 96.

[0032] As one implementation method, the aquaculture system also includes a sliding sleeve 10, an annular baffle 11 and an elastic element 12. The sliding sleeve 10 is located below the bottom plate 91 and is slidably connected to the return water pipe 6. The annular baffle 11 is arranged around the sliding sleeve 10 and is fixedly connected to the sliding sleeve 10. The elastic element 12 applies an upward elastic force so that the upper side of the annular baffle 11 fits against the lower side of the support plate 92.

[0033] The above settings prevent the inlet 7 from becoming clogged when pouring out impurities.

[0034] like Figure 4 When the filter mechanism 9 is installed on the inlet 7, the annular baffle 11 is located below the bottom plate 91. At this time, the filter screen 94 filters impurities. When the impurities are poured out, the filter mechanism 9 is lifted away, and the elastic element 12 applies an upward force to the annular baffle 11, so that the water surface is between the upper and lower sides of the annular baffle 11. Figure 5 At this time, an annular baffle 11 blocks impurities on the water surface from entering, preventing impurities from clogging the water inlet 7.

[0035] As one implementation method, the aquaculture system also includes a retaining ring 13, which is locked onto the return water pipe 6. The elastic element 12 is set as a spring, which is sleeved on the return water pipe 6. The upper end of the spring is connected to the sliding sleeve 10, and the lower end of the spring is connected to the retaining ring 13.

[0036] Specifically, such as Figure 4 When the filter mechanism 9 is installed at the water inlet 7, the spring is in a compressed state. Under the action of gravity of the filter mechanism 9, the spring is compressed. When the filter mechanism 9 is removed, the spring extends and lifts the annular baffle 11 through the sliding sleeve 10.

[0037] As one implementation method, the aquaculture system also includes a biological filter 14, through which a pumping mechanism sends water from the storage tank 4 into the aquaculture tank 3.

[0038] The above settings enhance the purification capacity of the aquaculture system.

[0039] The biological filter 14 of this application is equipped with biological packing material. When water passes through the biological filter 14, the biological packing material in the biological filter 14 purifies the water, and the water pumped into the aquaculture pond 3 by the pumping mechanism is cleaner.

[0040] In one implementation, the opening of the biological filter 14 is higher than the opening of the aquaculture pond 3. The pumping mechanism includes a lift pump 15, a first pipe section 16 and a second pipe section 17. The lift pump 15 is installed in the water storage tank 4. The lower end of the first pipe section 16 is connected to the lift pump 15, and the upper end of the first pipe section 16 extends above the biological filter 14. One end of the second pipe section 17 is installed on the upper side of the biological filter 14, and the other end of the second pipe section 17 extends above the aquaculture pond 3.

[0041] Specifically, the booster pump 15 pumps water from the storage tank 4 into the biological filter tank 14 through the first pipe section 16. After the water level in the biological filter tank 14 is higher than the second pipe section 17, the water in the biological filter tank 14 enters the aquaculture tank 3 through the second pipe section 17 under the action of gravity.

[0042] As one implementation method, the aquaculture pond 3 is equipped with multiple return water pipes 6, including a main water pipe 61 and multiple branch water pipes 62. The branch water pipes 62 penetrate through the bottom of the aquaculture pond 3. The water inlet 7 is located at the upper end of the branch water pipe 62, the lower end of the branch water pipe 62 is connected to the main water pipe 61, and the water outlet 8 is located at one end of the main water pipe 61.

[0043] Specifically, the aquaculture pond 3 of this application is set up with three water distribution pipes 62, and the number of water distribution pipes 62 is three. The three water distribution pipes 62 correspond one-to-one with the three aquaculture ponds 3. The water inlet 7 is set at the upper end of the water distribution pipe 62. The lower ends of the three water distribution pipes 62 are all connected to the main water pipe 61. The water in the aquaculture pond 3 is collected by the water distribution pipes 62 and then flows into the water storage pond 4 through the main water pipe 61.

[0044] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
