Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture, and particularly relates to a water purification circulation reverse osmosis oxygenation pre-filtering system for aquaculture products. Background Art

[0002] In the field of aquaculture products, water quality management is one of the key factors affecting the aquaculture effect and product quality. In traditional aquaculture methods, the water quality of aquaculture ponds is often affected by feed residues, fish excreta, and external environmental pollutants, resulting in eutrophication of water bodies, a decrease in dissolved oxygen content, and the accumulation of harmful substances such as ammonia nitrogen and nitrates, thereby affecting the growth rate and health status of aquaculture animals. In addition, traditional water purification methods usually rely on chemical agents or physical filtration. These methods not only have high costs and complex operations, but may also introduce new pollution sources and cause secondary pollution to the aquaculture environment.

[0003] In order to overcome the water quality management problems in traditional aquaculture methods, in recent years, researchers have begun to explore more environmentally friendly and efficient water purification and recycling technologies. Among them, water purification systems based on ecological principles have attracted much attention due to their low cost, easy maintenance, and pollution-free characteristics. Such systems achieve the self-purification and recycling of water quality through the synergistic action of natural factors such as plants and microorganisms by constructing ecological units such as artificial wetlands and aquatic plant planting areas.

[0004] However, there are still some deficiencies in the existing ecological water purification systems in practical applications, such as low purification efficiency, large floor area, and complex maintenance and management. Therefore, this application provides a water purification circulation reverse osmosis oxygenation pre-filtering system for aquaculture products to meet the needs. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide a water purification circulation reverse osmosis oxygenation pre-filtering system for aquaculture products to solve the deficiencies existing in the practical application of the existing ecological water purification systems, such as low purification efficiency, large floor area, and complex maintenance and management.

[0006] To solve the above technical problems, the utility model provides the following technical solutions:

[0007] A water purification circulation reverse osmosis oxygenation pre-filtering system for aquaculture products, comprising: an aquaculture pond filled with aquaculture water; a plurality of supports arranged in a staggered manner to divide the aquaculture pond into a feeding area and a planting area; a first frame and a second frame, with a first filter screen and a second filter screen respectively arranged inside the frames, and the first frame and the second frame are stacked on top of the planting area in an overlapping manner; a pipe interface fixed at the intersection of the supports, and the bottom of the pipe interface is communicated with a fixing seat, and a plurality of air holes for aeration are opened on the side wall of the fixing seat.

[0008] Preferably, it further includes an air pump, which is fixed outside the breeding pond. The output end of the air pump is hermetically connected to an air pipe, and the end of the air pipe far from the air pump is hermetically connected to a pipe interface.

[0009] Preferably, there are two types of radial cross-sections of the brackets, namely T-shaped and L-shaped. The T-shaped brackets are located at the transition position between the two planting areas, and the L-shaped brackets are located at the transition position between the feeding area and the planting area.

[0010] Preferably, the first filter screen and the second filter screen are respectively arranged to completely cover the middle hollow areas of the first frame and the second frame.

[0011] Preferably, the pore size of the first filter screen is larger than that of the second filter screen.

[0012] Preferably, it further includes a fixing block, which is fixed on the inner side wall of the breeding pond and has the same setting height as the bracket, and is used for lapping the first frame.

[0013] Preferably, the areas below the brackets where the planting area and the feeding area are located are separated by a partition board. The partition board is provided with a plurality of through grooves arranged in a straight line, and the width of the through grooves is smaller than the pore size of the second filter screen.

[0014] Preferably, the feeding area is filled with fillers for adsorbing impurities in the water, and submerged aquatic plants are planted in the planting area.

[0015] Compared with the prior art, the present utility model has at least the following beneficial effects:

[0016] The design structure is compact. By dividing the breeding pond into a feeding area and a planting area, and isolating the planting area through multiple filter screens, it can avoid the herbivorous fish in the feeding area and the breeding area from gnawing on the planted plants and damaging the functionality of the planting area. By setting a fixing seat for aerating the water body, and cooperating with the photosynthesis of the aquatic plants in the planting area to generate oxygen, the two work together to keep the dissolved oxygen content in the water body at a relatively high level and improve the survival rate of the cultured fish. By filling the feeding area with fillers such as activated carbon packets or cinder, it can adsorb and remove harmful substances such as organic matter, residual chlorine, and heavy metal ions in the water, playing a role in purifying the water quality. The aquatic plants in the planting area can supplement the oxygen content in the water body while absorbing nutrients and wastes in the water, such as ammonia nitrogen and nitrates, which helps to maintain the ecological balance of the water body, reduce the phenomenon of water body eutrophication, and further improve the water quality.

Detailed implementation manners

[0024] The following will describe in detail a water purification circulation reverse osmosis oxygenation pre-filtering system for aquaculture products provided by the present utility model in conjunction with the accompanying drawings and specific embodiments. At the same time, it should be noted here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. For some well-known technologies, those skilled in the art can also implement them in other alternative ways; and the accompanying drawings are only for more specifically describing the embodiments and are not intended to specifically limit the present utility model.

[0025] As Figure 1 - Figure 4 shown, an embodiment of the present utility model provides a water purification circulation reverse osmosis oxygenation pre-filtering system for aquaculture products, including: an aquaculture pond 1 filled with aquaculture water inside; a plurality of brackets 6, which are arranged in a staggered manner and divide the aquaculture pond 1 into a feeding area 4 and a planting area 5, and also include an aquaculture area, which communicates with the feeding area 4; a first frame 9 and a second frame 10, with a first filter screen 11 and a second filter screen 12 respectively arranged inside the frames, and the first frame 9 and the second frame 10 are stacked up and down and lapped at the top position of the planting area 5; a pipe interface 7, fixed at the intersection of the brackets 6, the bottom of the pipe interface 7 is connected to a fixing seat 14, and a plurality of aeration holes 15 for aeration are opened on the side wall of the fixing seat 14.

[0026] Among them, the feeding area 4 is filled with fillers such as activated carbon packets or cinder, which can adsorb and remove harmful substances such as organic matter, residual chlorine, and heavy metal ions in the water, playing a role in purifying the water quality. The planting area 5 is planted with perennial submerged aquatic plants such as hydrilla verticillata or chlorella vulgaris. While supplementing the oxygen content in the water body, it can also absorb nutrients and wastes in the water, such as ammonia nitrogen and nitrates, which helps to maintain the ecological balance of the water body, reduce the phenomenon of water eutrophication, and further improve the water quality.

[0027] By dividing the aquaculture pond 1 into a feeding area 4 and a planting area 5, and isolating the planting area 5 through multiple layers of filters, it is possible to prevent the herbivorous fish in the feeding area 4 and the aquaculture area from grazing on the planted plants and damaging the functionality of the planting area 5. By providing a fixed seat 14 for aerating the water body and cooperating with the photosynthesis of the aquatic plants in the planting area 5 to generate oxygen, the two work together to keep the dissolved oxygen content in the water body at a relatively high level, improving the survival rate of the cultured fish.

[0028] Such as Figure 1 As shown, it also includes an air pump 2, which is fixed outside the aquaculture pond 1. The output end of the air pump 2 is hermetically connected to an air pipe 3, and one end of the air pipe 3 far from the air pump 2 is hermetically connected to the pipe interface 7.

[0029] Among them, the air pump 2 serves as a gas supply source, and a hermetic connection technology is adopted between its output end and the air pipe 3. This connection is usually achieved through methods such as threaded interfaces, quick connectors, or flange connections to ensure a tight fit between the two, thereby allowing gas to flow smoothly and efficiently from the air pump 2 into the air pipe 3. To ensure the firmness and tightness of the connection, sealing materials such as sealing washers, O-rings, or thread sealants are usually used at the connection to effectively prevent gas leakage during transmission.

[0030] Such as Figure 2 And Figure 4 As shown, the radial cross-section of the bracket 6 has two types, namely T-shaped and L-shaped. The T-shaped bracket 6 is located at the transition position between the two planting areas 5, and the L-shaped bracket 6 is located at the transition position between the feeding area 4 and the planting area 5. One end of the bracket 6 is fixedly connected to the inner side wall of the aquaculture pond 1, and the bracket 6 is made of stainless steel material with strong corrosion resistance.

[0031] Among them, the T-shaped bracket 6 presents a structure in which a crossbar intersects perpendicularly with a vertical bar in the radial cross-section, similar to the English letter "T". The crossbar is placed horizontally to connect different parts in the aquaculture pond 1, while the vertical bar extends vertically upward to provide additional support for the side wall of the frame to prevent the frame from slipping; the L-shaped bracket 6 presents a right-angled shape in the radial cross-section. Compared with the T-shaped bracket 6, the crossbar section does not protrude from the vertical bar, similar to the English letter "L", to avoid blocking the side wall of the feeding area 4.

[0032] As Figure 2 shown, the first filter screen 11 and the second filter screen 12 are respectively set to completely cover the middle hollow areas of the first frame 9 and the second frame 10; and the filter pores of the first filter screen 11 are larger than those of the second filter screen 12.

[0033] Furthermore, the number of filter screens can be set to more than two. In the early stage of aquaculture, the fry are isolated by the filter screen with smaller pores in the upper layer. At the same time, the aquatic plants in the planting area 5 are put into the pond and planted together with the fry to prevent the fry from eating the plant seedlings. As the fry grow to a certain size, the filter screen located above is removed, and the impurities attached to the filter screen are taken away from the aquaculture pond 1 together, which plays a certain cleaning role. At this time, the filter screen with larger pores below plays a role in isolating the fish. As the fry grow, the topmost filter screen is taken out in turn until the cultured fish reach the size for sale, and all the filter screens are taken out. At this time, the plants in the planting area 5 can be used as fish feed, making reasonable use of resources and reducing aquaculture costs.

[0034] As Figure 2 shown, it further includes a fixing block 8, which is fixed on the inner side wall of the aquaculture pond 1 and has the same height as the bracket 6, and is used for lapping the first frame 9, playing a supporting role for the side of the frame far from the bracket 6, and the fixing block 8 and the bracket 6 are made of the same stainless steel material.

[0035] As Figure 3 shown, the planting area 5 and the feeding area 4 in the area below the bracket 6 are separated by a partition board. A plurality of straight-line arranged through grooves 13 are formed on the partition board, and the width of the through grooves 13 is smaller than the filter pores of the second filter screen 12.

[0036] With this setting, it is avoided that the fed feed mixes into the planting area 5, resulting in the cultured fish being unable to eat and causing water pollution. Moreover, the through grooves 13 are formed on the partition board, allowing water to flow freely between different areas. This design improves the frequency and efficiency of water exchange, helps to discharge the water rich in pollutants in time, and introduces fresh water.

[0037] For the technical solution provided by the present utility model, in the early stage of breeding, an appropriate amount of breeding water is injected into the breeding pond 1; the mounting brackets 6 are installed to ensure that the brackets 6 are firmly fixed on the inner side wall of the breeding pond 1 and are staggered to separate the feeding area 4, the planting area 5 and the breeding area; the first frame 9 and the second frame 10 are installed, and through the support of the brackets 6 and the fixing blocks 8, they are overlapped in a stacked manner at the top position of the planting area 5; activated carbon packets or cinder and other fillers are filled inside the feeding area 4; submerged aquatic plants such as Hydrilla verticillata or Chara vulgaris are planted in the planting area 5; the air pump 2 is fixed outside the breeding pond 1, and the output end of the air pump 2 is connected to the air pipe 3 through a sealing connection technology (such as a threaded interface, a quick connector or a flange connection); the other end of the air pipe 3 is hermetically connected to the pipe interface 7 to ensure that gas can flow smoothly into the pipe interface 7; check whether all connections are firm, and use sealing materials such as sealing washers, O-rings or thread sealants to prevent gas leakage; debug the air pump 2 to ensure that it can work normally and provide sufficient aeration volume to the water body.

[0038] During the breeding process, a suitable filter screen is selected according to the size of the fry and installed on the first frame 9 and the second frame 10. Generally, the upper filter screen has smaller pores and is used to isolate the fry and prevent it from nibbling on the plant seedlings in the planting area 5; as the fry grows, the topmost filter screen is taken out successively as needed, and the impurities attached to the filter screen are taken away from the breeding pond 1 together. At the same time, the lower filter screen with larger pores continues to play an isolation role; regularly check the water quality conditions of the feeding area 4 and the planting area 5, and add or replace the fillers as needed; observe the growth status of the fish, and adjust the feed feeding amount and feeding time in a timely manner; use the fillers in the feeding area 4 to adsorb and remove harmful substances such as organic matter, residual chlorine, and heavy metal ions in the water; the aquatic plants in the planting area 5 produce oxygen through photosynthesis and absorb nutrients and wastes (such as ammonia nitrogen, nitrate, etc.) in the water, which helps to maintain the ecological balance of the water body; aerate the water body through the air pump 2 to increase the dissolved oxygen content in the water body and improve the survival rate of the cultured fish; regularly check and clean the dirt and impurities on the filter screen and the fixing seat 14 to ensure the normal operation of the system and the filtering effect.

[0039] At the end of the breeding period, when the cultured fish reach the sellable size, all the filter screens are taken out, and the aquatic plants in the planting area 5 are used as fish feed to reasonably utilize resources and reduce breeding costs.

In order to enable the public to have a thorough understanding of the present utility model, specific details are described in detail in the above preferred embodiments of the present utility model. However, those skilled in the art can fully understand the present utility model even without the description of these details. In addition, well-known methods, processes, procedures, components and circuits, etc. are not described in detail in order to avoid unnecessary confusion to the essence of the present utility model.

[0041] The above description is only a preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
