Description

Technical Field

[0001] This utility model relates to the field of aquaculture equipment, specifically a fully enclosed three-dimensional aquaculture device. Background Technology

[0002] A breeding farm is a place where a certain number of domesticated animals such as livestock and poultry, or wild animals such as deer, musk deer, foxes, minks, otters, and quails are raised and bred in a concentrated manner. Most existing large-scale livestock farms adopt a double-row, single-layer open-style shed farming model, which occupies a large area. Pollutants such as manure, odor, garbage, and pathogens generated during the farming process are directly and freely discharged, causing serious pollution to the surrounding air, water, and soil, endangering human health and the growth of animals and plants. The open structure cannot effectively isolate external pathogens, hindering the prevention and control of infectious diseases in livestock and poultry. Furthermore, environmental protection requirements limit the location of large-scale farms to remote areas, increasing the cost of transporting livestock supplies and distributing products. Therefore, there is an urgent need for a livestock farming device that combines high space utilization, zero pollution emissions, and intelligent operation. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of existing large-scale breeding equipment and provide a fully enclosed three-dimensional breeding device that achieves zero emissions and zero pollution in the breeding farm, improves land utilization, reduces electricity and labor costs, and can flexibly change the species being raised. It is suitable for scenarios with many mountains and little land, as well as areas around towns.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A fully enclosed three-dimensional aquaculture device includes a closed cylindrical box enclosed by an outer wall. The bottom of the closed cylindrical box is equipped with an underground manure storage and maturation treatment system, and the top is equipped with an odor storage and purification system. The interior of the closed cylindrical box contains multiple levels of aquaculture space. Each level includes four feeding operation areas and four fan-shaped feeding pens. The feeding operation areas are located between the outer wall and the feeding pens, separated by an arc-shaped partition wall with feeding troughs. The feeding pens are divided into dry and wet areas. The ground of the dry area slopes towards the wet area by 3-5%, facilitating the flow of manure into the wet area. The wet area is equipped with a manure discharge device connected to the manure storage and maturation treatment system. Four straight lanes are provided between the four feeding pens. The facility consists of four straight passageways arranged in a cross shape. The outer ends of each passageway connect to the feeding and operation area, while the inner ends connect to a central circular passageway. A odor emission chimney is located at the center of the circular passageway, and this chimney is connected to both an underground manure storage and maturation system and an odor storage and purification system. A sliding automatic closing door for animals and personnel is installed on the side of the dry area near the straight passageways. Manure conveying chims are also located outside the partition walls near the top of the wet area in each of the four feeding pens. These chims are also connected to the odor storage and purification system, and each chimney contains a vertical manure conveying pipe. A manure discharge device is connected to the manure conveying pipe, and the bottom of the manure conveying pipe is connected to the manure storage and maturation system.

[0005] This utility model's fully enclosed three-dimensional aquaculture device adopts a fully enclosed cylindrical box design, combined with a bottom underground manure storage and maturation treatment system and a top odor storage and purification system. It can perform full-process sealed treatment of manure and odor generated during the aquaculture process, effectively preventing pollutant discharge and achieving zero pollution and zero harm, avoiding odor damage and ecological impact on the surrounding environment. The enclosed cylindrical box has multiple layers of aquaculture space, with four feeding operation areas, four fan-shaped feeding pens, and multiple passageways on each layer, greatly improving land utilization. The feeding operation areas and pens are separated by arc-shaped partition walls with feeding troughs. An odor emission chimney is located at the center of the circular passageway, ensuring independent and efficient operation of each functional area while facilitating personnel access and mechanized operation. The animal pens are divided into dry and wet areas. The dry area's 3-5% slope guides flushing wastewater and manure to automatically flow into the wet area, then through a manure discharge device and a vertical conveying pipe directly to the underground manure storage and maturation system. This eliminates the need for frequent manual cleaning, significantly reducing the labor intensity of animal keepers. The dry area is equipped with a sliding automatic closing door, which facilitates the passage of animals and personnel while maintaining the enclosure's airtightness, reducing the invasion of external pathogens and enhancing disease prevention capabilities. Simultaneously, the manure conveying chimney is connected to an odor storage and purification system, ensuring that odors generated during manure transportation and the manure storage and maturation system are also efficiently purified, further enhancing environmental protection. The overall structure balances environmental friendliness, efficiency, and practicality, providing a high-quality solution for large-scale animal husbandry.

[0006] As a further description of the above technical solution: the manure discharge device includes a perforated plate installed on the wet area floor, with an inclined drain plate below the perforated plate. The lower end of the drain plate has a perforation for manure to pass through, and a floor drain is installed at the perforation. A drain pipe is connected below the floor drain and is connected to the manure delivery pipe. The perforated plate on the wet area floor allows manure and manure residue to pass through and fall onto the drain plate below by gravity. The inclined drain plate guides the manure to flow naturally to the lower perforation using gravity, eliminating the need for additional power, thus saving energy and reducing equipment failure rate. Simultaneously, the floor drain at the perforation and connection to the drain pipe enables sealed manure delivery, effectively preventing manure leakage from polluting the pen environment and breeding bacteria. Furthermore, the connection between the drain pipe and the manure delivery pipe allows the manure to be smoothly introduced into an underground manure storage and treatment system for treatment, ensuring a continuous and efficient process for manure collection and transportation, significantly reducing manual cleaning workload, and further improving the convenience and environmental friendliness of livestock management.

[0007] As a further description of the above technical solution: the manure storage and maturation treatment system includes a manure storage tank located below the manure conveying chimney and connected to the manure conveying pipe. The manure storage tank is connected to a maturation sludge tank and a manure fermentation tank respectively through an automatic manure separation device. The manure fermentation tank is connected to a maturation clear water tank. A high-lift water pump is installed at the outlet of the maturation clear water tank to pump the clear water in the maturation clear water tank. The clear water in the maturation clear water tank can be pumped to the flushing water tank at the top of the closed cylindrical tank as feed flushing water, or it can be pumped to the water storage tank (or pond) outside the closed cylindrical tank for crop irrigation, realizing the recycling of water resources and saving the cost of aquaculture water. The maturation sludge in the maturation sludge tank can be transported to an organic fertilizer processing plant for the production of organic fertilizer, turning aquaculture waste into organic fertilizer resources, turning waste into treasure, and increasing the added value of aquaculture. This manure storage and maturation system receives manure from a manure delivery pipe into a manure storage tank. An automatic manure separation device automatically separates the manure into manure sludge and manure liquid. The manure sludge is transported to a maturation tank as raw material for subsequent organic fertilizer processing, while the manure liquid is transported to a closed, three-stage fermentation tank. The clean water from the fermentation process is then sent to a maturation clean water tank for reuse. The entire maturation process is a continuous closed loop, ensuring complete collection and step-by-step treatment of the manure, preventing leakage and pollution during the process. It balances environmental protection and resource regeneration, meeting zero-emission requirements while generating economic benefits, significantly improving the sustainability of the livestock industry.

[0008] As a further description of the above technical solution: the odor storage and purification system includes an odor storage and sterilization chamber placed on top of a closed cylindrical box and connected to the odor emission chimney and the sewage conveying chimney. The odor storage and sterilization chamber is connected to the biological deodorization and purification equipment through an exhaust fan. The odor storage and sterilization chamber is doubly connected to the odor emission chimney (which receives odors generated by the underground manure storage and maturation system) and the manure conveying chimney (which receives odors escaping during manure conveying). This allows for the comprehensive collection of odors generated at different stages of the entire breeding process, preventing localized odor leaks and environmental pollution. The odors rising from the odor emission chimney and manure conveying chimney are first temporarily stored and then subjected to preliminary spray deodorization and infrared light sterilization in the odor storage and sterilization chamber. This buffers peak odor emissions, stabilizes subsequent processing loads, and kills pathogens carried in the odors in advance, reducing the risk of disease transmission. The exhaust fan provides stable power to ensure efficient delivery of odors to the biological deodorization and purification equipment. Compared to chemical purification, biological deodorization is more environmentally friendly, produces no secondary pollution, and effectively degrades harmful components in the odors (such as ammonia and sulfides). The final exhaust gas is odorless and meets environmental standards, completely solving the problems of odor nuisance and air pollution caused by breeding.

[0009] As a further description of the above technical solution: the feeding operation area is equipped with a feed storage device and an automated feeding machine. The automated feeding machine is used to transport the feed from the storage device into the feeding trough. The feed storage device enables centralized storage of feed, ensuring the stability of feed supply and avoiding problems such as moisture, contamination, or supply interruption caused by scattered feed storage. The automated feeding machine can accurately transport the feed from the storage device to the feeding trough, eliminating the need for manual mixing and feeding, significantly reducing the labor intensity of the feeders and lowering labor costs. At the same time, automated conveying can achieve timed and quantitative feeding, avoiding spillage and waste during manual feeding, controlling feed loss, and reducing direct contact between people and feed / troughs, reducing the risk of cross-contamination of pathogens, and ensuring feed hygiene and livestock feeding safety.

[0010] As a further description of the above technical solution: The outer wall has windows, and louvers are installed inside the windows. The louvers are made of cadmium telluride photovoltaic glass. Cadmium telluride photovoltaic glass can achieve photoelectric conversion even on cloudy days and in low-light environments, generating electricity continuously without relying on strong light. The generated electricity can be directly supplied to the automated equipment (such as feeding machines, temperature control equipment, etc.) inside the cylindrical enclosure, significantly reducing dependence on the national power grid, reducing electricity costs for livestock farming, and providing key support for energy self-sufficiency in fully enclosed farming. Cadmium telluride photovoltaic glass is made by depositing a cadmium telluride semiconductor thin film on a glass substrate and also has good light transmittance, allowing natural light to enter the enclosed cylindrical enclosure evenly, effectively solving the problem of insufficient lighting in multi-layer fully enclosed farming spaces, creating a near-lighting environment for livestock. The natural light environment is conducive to their growth and development; the louvered structure design retains air circulation channels, allowing fresh air from the outside to flow naturally into the feeding and operation area and pens, meeting the oxygen needs of livestock and poultry; at the same time, the blade angle can be reasonably set, and with the chimney effect and the exhaust fans installed in the feeding pens, it prevents foul gases from flowing back to the outside of the cylinder box, ensuring ventilation while maintaining unidirectional airflow inside, further consolidating the zero-pollution effect of fully enclosed breeding, and achieving a multi-effect combination of power generation, lighting, ventilation, and air intake, providing a strong guarantee for the dual optimization of the breeding environment and operating costs.

[0011] As a further description of the above technical solution: an exhaust louver and an exhaust fan are installed on the partition wall between the sewage conveying chimney and the wet area. The wet area is where manure collects and odors accumulate. The exhaust louvers are directly connected to the manure conveying chimney, which in turn connects to the top odor storage and purification system. This allows odors from the wet area to pass through the exhaust louvers into the manure conveying chimney, preventing odor buildup and diffusion within the pens, reducing odor at the source, and ensuring a clean breathing environment for livestock. The combined effect of the exhaust fans and the chimney promotes the discharge of odors from the wet area into the manure conveying chimney, reducing the backflow of odors from the chimney back into the wet area, preventing secondary air pollution, and maintaining a clean, one-way airflow within the pens. The odors rise through the manure conveying chimney to the odor storage and purification system for storage and purification, ensuring complete odor treatment and no leakage. Furthermore, while discharging odors, excess moisture in the wet area is simultaneously removed, reducing humidity and creating a breeding ground for mold and bacteria, further improving pens hygiene and promoting healthy livestock growth.

[0012] As a further description of the above technical solution: The curved partition wall and the partition wall of the feeding pen near the straight passageway both have windows, and tempered glass louvers are installed inside the windows. Tempered glass has high light transmittance, allowing natural light to be efficiently introduced into the feeding pen, especially suitable for the lighting needs of multi-level, three-dimensional farming, preventing the pen from becoming dark due to its fully enclosed structure, creating a near-natural lighting environment for livestock and poultry, promoting their growth and development, and also providing a clear view for personnel operating in the straight passageway; the louver structure also guides fresh air into the feeding pen, supplementing the oxygen needed by the livestock and poultry. At the same time, thanks to the angle design of the louvers and the function of the exhaust fan, it prevents foul gases generated in the feeding pen from flowing back into the feeding operation area or passageway, forming a closed-loop air circulation system with the cadmium telluride louvers on the outer wall and the exhaust louvers in the wet area, maintaining... The clean air in the operating area and passageways reduces the impact of odors on personnel and livestock. The tempered glass is highly durable and impact-resistant, resisting collisions during livestock activities or scratches from moving equipment within the passageways. It is not easily broken, and its smooth surface is easy to clean, allowing for quick removal of pollutants such as feces and dust, reducing the risk of bacterial growth and minimizing maintenance frequency and costs. The high light transmittance of tempered glass also aids in observation and disease prevention, allowing personnel to directly observe the feeding and activity status of livestock in the pens from the straight passageway without opening closed doors. This avoids interfering with the normal growth of livestock and reduces direct contact between the external environment and the pens, lowering the risk of disease transmission and further strengthening the disease prevention advantages of fully enclosed farming.

[0013] As a further description of the above technical solution: The feeding operation area is also equipped with air conditioning equipment, which can accurately control the temperature to ensure a constant environment. This effectively offsets the temperature changes caused by heat dissipation from equipment in the multi-layered enclosed space and external climate fluctuations, stabilizing the temperature of the feeding operation area within a suitable range. This provides a constant temperature operating environment for core equipment such as feed storage devices and automated feeding machines, reducing the risk of failure due to temperature imbalance, and preventing feed from becoming damp due to high temperature or clumping due to low temperature, thus ensuring feed quality. The air conditioning equipment can also be linked with the power generation function of the cadmium telluride low-light power-generating glass on the exterior wall and the ventilation function of the louvers and tempered glass louvers on the exterior wall. Through intelligent control, the operating power can be adjusted as needed, and the electricity generated by the cadmium telluride low-light power-generating glass can even be used to supply power, further reducing energy consumption.

[0014] As a further description of the above technical solution: the feeding operation area is also equipped with an intelligent operation room, an electrical control room, and a veterinary room. The intelligent operation room can centrally control automated feeding equipment, air conditioning temperature control, ventilation louvers, and other equipment to achieve timed and quantitative feeding and real-time adjustment of environmental parameters, eliminating the need for manual operation and significantly reducing labor input. At the same time, it can promptly detect abnormalities through data monitoring (such as feed residue, pen temperature and humidity), improving the precision and responsiveness of breeding management. The electrical control room ensures the stability of the power system and can comprehensively manage the power generation storage of the cadmium telluride low-light power generation glass, AC and DC power. The conversion and power distribution of various devices prevent downtime of automated equipment due to power fluctuations, laying a solid power foundation for the continuous operation of the entire system; the veterinary room enhances the timeliness of disease prevention and control, and can carry out livestock and poultry health checks, vaccinations, and treatment of common diseases nearby without having to transfer livestock and poultry out of the closed environment, reducing the risk of infection from external contact, while also being able to quickly handle sudden outbreaks of disease and prevent the spread of epidemics; the synergistic effect of these three elements provides support for fully enclosed three-dimensional farming in terms of management efficiency, system stability, and disease prevention and control, realizing intelligent and stable farming operations, and further reducing farming risks and management costs.

[0015] Compared with the prior art, the beneficial effects of this utility model are: This utility model's fully enclosed three-dimensional aquaculture device achieves a comprehensive breakthrough in environmental protection, high efficiency, economy, and adaptability: Through a fully enclosed multi-layer cylindrical tank design, combined with a manure storage and maturation system and an odor storage and purification system, it effectively solves many environmental pollution problems caused by pollution sources (manure, odor, garbage, viruses) in centralized farms. It achieves a fully enclosed, zero-emission, zero-pollution, zero-harmful environment, with no foul odors spreading into the air, thus avoiding pollution and odor damage to the surrounding environment. Therefore, it is not limited to remote locations. The multi-layered three-dimensional layout combines multiple feeding operation areas on each layer with four fan-shaped feeding pens. The design of the enclosure and multiple passageways not only saves 8-10 times the land required for building breeding sheds, but also more effectively realizes large-scale, automated, and multi-species circular industrial development, producing tens of thousands of tons of high-quality, safe, and green poultry and livestock meat annually, solving people's daily necessities locally. This pollution-free breeding complex, being fully enclosed, will not cause pollution to the environment. The outer walls of the enclosed cylindrical enclosure are made of cadmium telluride photovoltaic glass with louvers, effectively solving the technical problems of lighting and ventilation. The theoretical conversion rate of cadmium telluride photovoltaic glass is as high as 33% (in actual applications, the power generation is 3% to 7.5% higher than that of monocrystalline silicon). A single 1.2 m × 1.6 m cadmium telluride photovoltaic glass can generate 260 kWh of electricity per year. The power generation of the cadmium telluride photovoltaic glass installed on the entire outer wall can fully meet the power needs of the entire breeding facility. The electrical control system is equipped with energy storage and AC / DC conversion devices, effectively reducing the operating costs of breeding and dependence on national electricity.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0025] A fully enclosed three-dimensional aquaculture device, such as Figure 1 - Figure 7 As shown, the enclosure includes a closed cylindrical box 1 surrounded by an outer wall 111. The outer wall 111 is constructed of weather-resistant granite blocks with standard dimensions of 600 mm × 200 mm × 150 mm. The outer wall 111 has windows with louvers 112 installed inside. The blades of the louvers 112 are made of cadmium telluride photovoltaic glass (purchased from Chengdu Zhongjiancai Optoelectronic Materials Co., Ltd.), and the blades are tilted with a certain gap between adjacent blades to meet the needs of lighting, ventilation and power generation. The bottom of the enclosed cylindrical box 1 is equipped with an underground manure storage and maturation system 18 for fermenting and maturing the generated manure; the top of the enclosed cylindrical box 1 is equipped with an odor storage and purification system 19 for purifying the generated odorous gases; the top of the enclosed cylindrical box 1 is equipped with a clear water pool 113, which is divided into a flushing water pool and a drinking water pool. The flushing water pool is used to hold water for flushing the livestock pens, and the drinking water pool is used to hold drinking water for the livestock. The clear water pool 113 is connected to the water supply network 114.

[0026] The enclosed cylindrical container 1 has multiple breeding spaces inside. The enclosed cylindrical container 1 is equipped with a crawler elevator 121, a car elevator 122 and a fire escape staircase 123. The crawler elevator 121 is generally used to transport equipment and materials, while the car elevator 122 is generally used for staff to go up and down. Each level of the breeding space includes four feeding operation areas 12 and four fan-shaped feeding pens 15. The feeding operation areas 12 are located between the outer wall 111 and the feeding pens 15, separated by an arc-shaped partition wall 13. The arc-shaped partition wall 13 is also constructed of granite blocks with dimensions of 600 mm × 200 mm × 150 mm. A feeding trough 131 is located below the arc-shaped partition wall 13, resting on the floor. The opening of the feeding trough 131 is located inside the feeding pen 15 for easy access for livestock to eat. Part of the feeding trough 131 is located outside the feeding pen 15, and its interior has a sloping ramp for easy feeding. A window is opened 1.5 meters from the floor in the arc-shaped partition wall 13, extending to the top. The window is fitted with tempered glass louvers 132 for easy observation of livestock and ventilation. The feeding operation area 12 also includes a feed storage device 125 and an automated feeding device 126. The automated feeding device 126 is as follows: Figure 7As shown, the system includes a mixing tank platform 1261 with wheels, a mixing tank 1262 with a mixing impeller 1263 and a feed inlet 1264 mounted on the mixing tank platform 1261, a discharge pipe 1265 at the outlet of the mixing tank 1262, and a screw conveyor inside the discharge pipe 1265 for mixing the feed in the storage device 125 and conveying it into the feeding trough 131; each feed operation area 12 is also equipped with an intelligent operation room 124, a veterinary room 127, an air conditioning unit 128, and an electrical control room 129. The intelligent operation room 124 is used for centralized control of automated feeding equipment, air conditioning temperature control, ventilation louvers, and other equipment; the veterinary room 127 is used for nearby livestock and poultry health checks, vaccinations, and diagnosis and treatment of common diseases; the air conditioning unit 128 is used for precise temperature control to ensure a constant environment and keep the temperature of the feeding operation area within a suitable range; and the electrical control room 129 ensures the stability of the power system.

[0027] Four straight passageways 141 are provided between the four breeding pens 15. The four straight passageways 141 are arranged in a cross shape. The outer end of the straight passageway connects to the breeding operation area 12, and the inner end connects to the central ring passageway 141. At the center of the ring passageway 142, there is a 3-meter diameter odor emission chimney 17. The odor emission chimney 17 is connected to the underground manure storage and maturation treatment system 18 and the odor storage and purification system 19. The gas generated by the underground manure storage and maturation treatment system 18 is transported to the waste odor storage and purification system 19 at the top for purification treatment. Near the outer wall of the odor emission chimney 17, the ring passageway 141 is also pre-buried with water supply and power lines. The water supply network 114, as well as the power supply line and network cable, are all laid through the pre-buried pipe 146.

[0028] The feeding pen 15 is divided into a dry area 151 and a wet area 152. The ground of the dry area 151 slopes towards the wet area 152 by 3-5% to facilitate the flow of feces into the wet area 152. The wet area 152 is equipped with a feces discharge device, which includes a drain plate 1521 installed on the floor of the wet area 152. Below the drain plate 1521 is an inclined sewage discharge plate 1522. The lower end of the sewage discharge plate 1522 has a hole for the passage of feces. A floor drain 1523 is installed at the hole, and a sewage pipe 1524 is connected below the floor drain 1523. Windows are also provided in the partition wall 143 between the feeding pen 15 and the straight passage 141, with tempered glass louvers 132 installed inside. The dry area 151, near the straight passage 141, also has a sliding automatic closing door 144 for animals and personnel to pass through. A fan-shaped manure conveying chimney 16 is also provided at the top of the feeding pen 15. The manure conveying chimney 16 is constructed of porous concrete blocks. Exhaust louvers 162 and exhaust fans are installed in the partition wall between the manure conveying chimney 16 and the wet area 152. The manure conveying chimney 16 is also connected to the odor storage and purification system. The manure conveying chimney 16 is connected to the manure conveying pipe 161, which is vertical. The sewage pipe 1524 of the manure discharge device is connected to the manure conveying pipe 161. The bottom of the manure conveying pipe 161 is connected to the manure storage and maturation treatment system 18, which can directly transport the manure produced by each layer of the breeding pen 15 downward to the underground manure storage and maturation treatment system 18 for biological maturation treatment. At the same time, a chimney effect is generated, which guides the malodorous gas discharged into the manure conveying chimney 16 through the exhaust louvers 162 upward to the odor storage and purification system 19 at the top for biological purification treatment.

[0029] The aforementioned manure storage and maturation system 18 includes a manure storage tank 181 located below the manure conveying chimney 16 and connected to the manure conveying pipe 161, a manure fermentation tank 182 connected to the manure storage tank 181, a maturation clear water liquid 184 connected to the manure fermentation tank 182, and a maturation manure sludge tank 182. After the manure is fermented and matured in the manure fermentation tank 183, it undergoes dry-wet separation. The liquid enters the maturation clear water tank 184 for storage and is connected to sewage treatment equipment or a sewage treatment plant through a pipeline for purification and discharge. The separated manure sludge is sent to the maturation manure sludge tank 184 for storage via a screw conveyor. The bottom of the enclosed cylindrical box 1 is also equipped with an underground garage 185 and a raw material warehouse 186 to facilitate the transportation of the matured manure sludge to an organic fertilizer processing plant.

[0030] The aforementioned manure storage and maturation system 18 includes a manure storage tank 181 located below the manure conveying chimney 16 and connected to the manure conveying pipe 161. The manure storage tank 181 is connected to a maturation sludge tank 182 and a manure fermentation tank 183 via an automatic manure separation device. The manure fermentation tank 183 is connected to a maturation clear water tank 184. A high-lift water pump is installed at the outlet of the maturation clear water tank 184. The manure storage tank 181 receives manure from the manure conveying pipe 161 and automatically separates it into sludge and manure liquid using the automatic manure separation device. The sludge is sent to the maturation sludge tank 182 for fermentation. The maturation sludge tank 182 is connected to a screw conveyor for outputting the matured sludge to an organic fertilizer processing plant as raw material for organic fertilizer processing (if it is cow manure, fermentation is not required; it is directly transported to a feed processing plant for drying and processing into feed for raising medicinal scorpions; poultry...). The manure can be directly transported to a feed processing plant for drying and processing into fish feed, transforming aquaculture waste into organic fertilizer resources, turning waste into treasure, and increasing the added value of aquaculture. The manure liquid is transported to the manure liquid fermentation tank 183, where EM rapid fermentation agent is added for closed three-stage fermentation, biologically converting the manure liquid into harmless clean water, which is then sent to the maturation clean water tank 184. It is then pumped by a high-lift pump to the flushing water pool at the top of the closed cylindrical tank 1 as flushing water for cleaning the pens, or it can be pumped to the water storage tank (or pond) outside the closed cylindrical tank for crop irrigation, realizing the recycling of water resources and saving aquaculture water costs. The entire maturation process is continuous and closed-loop, ensuring that all manure liquid is collected and treated step by step, avoiding leakage and pollution in the middle, taking into account both environmental protection and resource regeneration, meeting the zero-emission requirements, creating economic benefits, and greatly improving the sustainability of the aquaculture industry.

[0031] The odor storage and purification system 19 includes an odor storage and sterilization chamber 191 located on top of a closed cylindrical box 1 and connected to an odor emission chimney 17 and a sewage conveying chimney 16. The odor storage and sterilization chamber 191 is connected to a biological deodorization and purification device 193 via an exhaust fan 192. The biological deodorization and purification device 193 is connected to a microbial incubator 194. Microorganisms use inorganic and organic matter in the waste gas as carbon and energy sources, maintain their life activities by degrading odorous substances, and decompose odorous substances into odorless substances such as carbon dioxide, water, and minerals, thereby achieving the purpose of purifying odorous gases.

[0032] The entire fully enclosed three-dimensional aquaculture device has a height of 3.6 to 4.8 meters and a total of 9 to 11 layers. On the one hand, it can increase the height of the manure conveying chimney 16 and the odor emission chimney 17 outlet. The higher the height, the greater the wind speed and the more significant the chimney effect, thus meeting the needs of natural and rapid ventilation of each layer. On the other hand, the fermentation of manure will generate heat, which will raise the gas temperature, and the rising hot air will further promote the chimney effect.

[0033] The working principle of this utility model for the pollution-free treatment of manure, garbage, and odor is as follows: Manure and garbage generated from animal husbandry are discharged into the manure conveying pipe 161 through the manure discharge device. Under gravity, they flow directly down to the manure storage tank 181 of the underground manure storage and maturation system 18, and then are sent to the manure fermentation tank for three-stage fermentation and maturation. Afterwards, dry and wet separation is performed. The liquid enters the maturation clear water tank 183 and is then piped to sewage treatment equipment or a sewage treatment plant for purification. The manure sludge enters the maturation sludge tank 184 and is finally directly sent to… The organic fertilizer production plant produces organic fertilizer; the odor generated by the livestock pen 15 enters the manure conveying chimney 16 through the exhaust louvers 162 under the action of the exhaust fan, and rises to the top of the odor storage and purification system 19 for purification using the chimney effect; the odor generated by the fermentation of the underground manure storage and maturation system 18 rises from the odor emission chimney to the biological deodorization and purification equipment 193 of the odor storage and purification system 19, and is converted into harmless and odorless substances such as carbon dioxide (CO2) and water (H2O) under the action of microorganisms, and is discharged harmlessly.

[0034] This utility model's fully enclosed three-dimensional aquaculture device achieves multi-dimensional breakthroughs and optimizations in existing aquaculture technologies: its multi-layered three-dimensional layout, combined with multiple feeding operation areas on each layer, fan-shaped feeding pens, and multiple passageways, significantly improves land utilization, breaking the limitation that traditional farms can only be built in remote areas, making it suitable for mountainous areas with limited land and for scenarios around towns; the manure produced during the feeding process is stored, fermented, and separated into wet and dry parts, with the liquid sent to wastewater treatment for purification and recycling, and the manure residue used as raw material for producing organic fertilizer; the odor is discharged after biological purification, completely solving the pollution problem of indiscriminate discharge of manure odor in existing open-type aquaculture, achieving zero emissions and zero pollution; the exterior walls are equipped with cadmium telluride power-generating glass louvers, simultaneously achieving self-generation, lighting, and ventilation. The device features wind power, reducing reliance on the national power grid and electricity costs. The installation and use of automated feeding equipment, intelligent operating rooms, electrical control rooms, and air conditioning equipment in the feeding area promotes intelligent management of the entire breeding process, reducing manpower input and operational errors. The fan-shaped feeding pens have separate wet and dry areas, ensuring a clean environment for livestock and poultry growth while allowing manure to automatically enter an underground manure storage and treatment system for processing, reducing the cost and labor intensity of manual manure cleaning. Each floor has a veterinary room for rapid disease prevention and control, preventing the spread of epidemics. This device also allows for flexible conversion of breeding species or expansion of integrated farming models, balancing environmental protection, efficiency, economy, and adaptability to fully meet the long-term development needs of large-scale farming.

[0035] This utility model relates to a fully enclosed, three-dimensional aquaculture system. A single-story building contains four fully enclosed feeding pens, and if calculated as a nine-story building, it has a total of 36 feeding pens, representing a small-scale aquaculture operation. To expand the scale of aquaculture or to raise multiple species, multiple identical fully enclosed, three-dimensional aquaculture systems can be constructed to form a large-scale integrated farm. When raising different animals, only the feeding facilities and feeding utensils need to be arranged according to the animals' living habits within the feeding pens; the functional layout of the main structure does not need to be altered.
