Description

Technical Field

[0001] This utility model relates to the field of aquaponics circulating filtration and oxygenation technology, and in particular to a high-efficiency aquaponics circulating filtration and oxygenation integrated device. Background Technology

[0002] Against the backdrop of continuous global population growth and accelerated urbanization, the demand for food is increasing, and traditional agriculture is facing severe challenges such as resource scarcity and environmental pollution. This is especially true in first-tier cities with limited resources, dense populations, and scarce arable land, where agricultural development urgently needs innovative models to address these challenges. The highly efficient aquaponics system, with its unique ecological characteristics, has become an important direction for modern agricultural development. Aquaponics is a new type of integrated farming system that combines aquaculture and hydroponics—two originally completely different agricultural techniques—through ingenious ecological design to achieve a scientific synergistic symbiosis. This results in fish farming without water changes and water quality concerns, and vegetables growing normally without fertilizer.

[0003] Among the aforementioned technologies, existing water filtration devices can achieve basic water purification, but they often lack efficient interception and adsorption structures, which can easily lead to incomplete removal of impurities and cumbersome maintenance, thereby affecting the stability of the aquaponics growth environment and making them inconvenient to use. Therefore, an efficient aquaponics circulatory filtration and oxygenation integrated device is proposed to solve the above problems. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figures 1-3 An embodiment of this utility model provides: a high-efficiency aquaponics circulating filtration and oxygenation integrated device, including a fish pond 1 with an open rectangular structure for fish farming, a bottom trough 5 with a long groove for receiving water body detachably connected to the outer wall of the fish pond 1 through a water circulation unit 8, a flow-through substrate planting area 2 fixedly connected to the top of the bottom trough 5, a planting trough 6 placed inside the flow-through substrate planting area 2, a water inlet trough 7 opened at the bottom of the flow-through substrate planting area 2, a filter assembly 4 provided on the outer wall of the flow-through substrate planting area 2, and a circulating oxygenation assembly 3 provided on the outer wall of the filter assembly 4;

[0030] The circulating oxygenation component 3 includes a water pump 31, which is a centrifugal pump made of corrosion-resistant engineering plastic. An L-shaped pipe 33, made of food-grade PVC, is fixedly connected to the left side of the pump 31. The L-shaped pipe 33 uses a 90-degree bend design to precisely change the water flow direction, enabling redirected water delivery from the pump 31 to a straight pipe 34. A straight pipe 34 is fixedly connected to the outer wall of the L-shaped pipe 33, and an outlet pipe 35 is fixedly connected to the bottom of the straight pipe 34. A horizontal pipe 32, a large-diameter rigid pipe, is fixedly connected to the outlet of the pump 31 at one end and to the filter pipe 41 of the filter component 4 at the other end. This horizontal pipe 32 is specifically designed to receive deeply purified water, ensuring stable water supply. A connecting pipe 37 is fixedly connected to the outer wall of the horizontal pipe 32. An oxygen connection pipe 36 is fixedly connected to the outer wall of pipe 37. A butterfly valve is installed inside the oxygen connection pipe 36. When the planted green vegetables do not have enough oxygen, oxygen is supplied by opening the butterfly valve after the oxygen pipe on the outer wall of the oxygen connection pipe 36. The bottom of the outlet pipe 35 is suspended above the fish pond 1. The connection pipe 37 is fixed by the mounting ring 9, which securely connects the filter assembly 4 and the circulating oxygenation assembly 3 to ensure water transfer. After purification, the water enters the circulating oxygenation assembly 3 through the connection pipe 37. After the water pump 31 is started, the water drawn by the horizontal pipe 32 is divided into two paths: one path is transported through the connection pipe 37. If the vegetables are short of oxygen, oxygen can be supplemented by connecting an oxygen pipe to the oxygen connection pipe 36 and opening the butterfly valve; the other path flows back to the fish pond 1 through the L-shaped pipe 33 and the straight pipe 34, and then through the suspended outlet pipe 35. The water naturally oxygenates as it falls, and the return flow is uniform and does not affect the fish.

[0031] Reference Figures 2-4The filter assembly 4 includes a filter pipe 41. The top of the filter pipe 41 has a slot, which is a long, narrow opening adapted to an arc-shaped cover 43. The edges of the slot are chamfered to facilitate the installation and removal of the arc-shaped cover 43. The outer wall of the sealing strip 42 is fixedly connected to the inside of the slot. An arc-shaped cover 43 is installed inside the slot of the filter pipe 41. The arc-shaped cover 43 is an arc-shaped plastic cover with anti-slip textured surfaces for easy gripping. The edge of the cover precisely matches the slot. An arc-shaped groove 44 is formed on the outer wall of the arc-shaped cover 43. The groove width perfectly matches the thickness of the sealing strip 42. When the arc-shaped cover 43 is closed, the sealing strip 42 can be completely embedded in the groove to achieve a tight seal. The outer wall of 42 is snapped into the inside of the arc-shaped groove 44. The inside of the filter pipe 41 is fixedly connected to the perforated placement base 45. The rear wall of the connecting pipe 37 is fixedly connected to the mounting ring 9. The rear wall of the connecting pipe 37 is fixedly connected to the outer wall of the filter pipe 41. The outer wall of the mounting ring 9 has a threaded hole. The connecting pipe 37 is fixedly installed by screws through the threaded hole of the mounting ring 9. The rear wall of the filter pipe 41 is fixedly connected to the inside of the bottom trough 5. Multiple sets of perforated placement bases 45 are provided, and the multiple sets of perforated placement bases 45 are evenly distributed along the length of the filter pipe 41. Wastewater containing fish excrement and uneaten food is diverted through the water circulation unit 8 and flows into the planting trough 6 through the water inlet 7 of the overflow substrate planting area 2 above the bottom trough 5. Vegetables absorb nitrogen, phosphorus, and potassium nutrients from the water to grow, while the substrate traps suspended impurities, completing preliminary purification and nutrient conversion. After initial filtration, the water enters the filter assembly 4 for deep purification: multiple sets of perforated bases 45 in the filter pipe 41 can support filter media such as activated carbon, adsorbing residual impurities and harmful microorganisms; the arc-shaped cover 43 is sealed by the sealing strip 42 to ensure sufficient filtration and facilitate later maintenance.

[0032] Working principle: During use, wastewater containing fish excrement and uneaten food is diverted through the water circulation unit 8 and flows into the planting trough 6 through the inlet 7 of the overflow substrate planting area 2 above the bottom trough 5. Vegetables absorb nitrogen, phosphorus, and potassium nutrients from the water to grow, while the substrate traps suspended impurities, completing preliminary purification and nutrient conversion. After initial filtration, the water enters the filter assembly 4 for deep purification: the multiple perforated bases 45 in the filter pipe 41 can hold filter media such as activated carbon, adsorbing residual impurities and harmful microorganisms; the arc-shaped cover 43 is sealed by the sealing strip 42 to ensure thorough filtration and facilitate later maintenance. The connecting pipe 37 is fixed by the mounting ring 9, which securely connects the filter assembly 4 and the circulating oxygenation assembly 3 to ensure water transfer. After purification, the water enters the circulating oxygenation assembly 3 through the connecting pipe 37. After the water pump 31 is started, the water drawn by the horizontal pipe 32 is divided into two paths: one path is transported through the connecting pipe 37. If the vegetables are deficient in oxygen, an oxygen pipe can be connected to the outside through the oxygen connecting pipe 36 and the butterfly valve can be opened to supplement oxygen; the other path is returned to the fish pond 1 through the L-shaped pipe 33 and the straight pipe 34, and then through the suspended outlet pipe 35. The water is naturally oxygenated when it falls, and the return flow is uniform and does not affect the fish.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
