Description

Technical Field

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

[0002] In the process of aquaculture such as fish, shrimp and crab, feed needs to be provided. After the aquatic animals consume the feed, the leftover feed and excrement will accumulate in the aquaculture equipment. If not treated in time, it will seriously pollute the aquaculture water quality, causing aquatic diseases or even death, thereby greatly reducing the yield.

[0003] Currently, livestock manure is typically separated by livestock equipment and then pumped to a sedimentation unit for concentration before further treatment. However, the manure separated by livestock equipment has a high water content, and directly pumping it to the sedimentation unit for concentration is inefficient, thus affecting manure collection efficiency. Furthermore, the entire manure discharge process relies on a power pump, resulting in high energy consumption. Utility Model Content

[0004] To address the aforementioned deficiencies in the existing technology, the purpose of this utility model is to provide a manure collection system and a breeding system that can collect manure efficiently and with low energy consumption, thereby reducing breeding costs.

[0009] The breeding pond, transfer pond and sedimentation pond are connected in sequence. There is a liquid level difference between the breeding pond and the transfer pond. A power pump is installed between the transfer pond and the sedimentation pond to collect the manure and sewage separated from the breeding pond and discharge it to the sedimentation pond for sedimentation and concentration.

[0010] In a preferred embodiment, in the first aspect of this utility model, a switch valve is provided on the pipeline between the breeding pond and the transfer pond.

[0012] In a preferred embodiment, in the first aspect of this utility model, a shut-off valve is provided on the pipeline between the aerator and the aquaculture pond.

[0013] In a preferred embodiment, in the first aspect of this utility model, the aquaculture pond includes a pond body and an air lifting device. The air lifting device includes a water inlet pipe, an air inlet pipe, and an oxygen mixing pipe. One end of the water inlet pipe and one end of the air inlet pipe are both connected to one end of the oxygen mixing pipe. The other end of the water inlet pipe is connected to the water inlet of the aquaculture pond. The other end of the air inlet pipe is connected to an aerator. The other end of the oxygen mixing pipe is connected to the pond body.

[0014] In a preferred embodiment, in the first aspect of this utility model, a check valve is provided inside the oxygen mixing pipe.

[0015] In a preferred embodiment, in the first aspect of this invention, the power pump is located inside the transfer tank and is suspended at the bottom of the transfer tank.

[0016] In a preferred embodiment, in the first aspect of this utility model, the power pump is suspended at the bottom of the transfer pool by a fixing structure.

[0028] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0029] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0031] See Figure 1 This utility model provides a manure collection system, including: an aquaculture pond 1 for raising aquatic animals and separating manure, a transfer pond 2 for collecting manure, and a sedimentation pond 3 for settling and concentrating manure. The aquaculture pond 1, the transfer pond 2, and the sedimentation pond 3 are connected in sequence. There is a liquid level difference between the aquaculture pond 1 and the transfer pond 2. A power pump 21 is provided between the transfer pond 2 and the sedimentation pond 3 to collect the manure separated from the aquaculture pond 1 and discharge it to the sedimentation pond 3 for sedimentation and concentration.

[0032] Aquaculture pond 1 is used for raising aquatic products such as fish, shrimp, and crabs. During the aquaculture process, uneaten feed is left after the aquatic products are consumed, and the aquatic products also excrete feces. The uneaten feed and feces accumulate in aquaculture pond 1, which, if not treated promptly, will severely pollute the aquaculture water, leading to aquatic diseases and even death, thus significantly reducing yield. Therefore, aquaculture pond 1 has a fecal separation function, which can separate and discharge feces, thereby preventing the accumulation of feces in aquaculture pond 1 and ensuring a good aquaculture environment.

[0033] The transfer tank 2 is used to collect manure. The manure separated from the breeding pond 1 has a high water content and can be discharged into the transfer tank 2 for centralized sedimentation. This ensures that the high-concentration manure is discharged into the sedimentation tank 3, where the manure is efficiently precipitated and concentrated, making it convenient for subsequent treatment after collection.

[0034] The breeding pond 1, the transfer pond 2, and the sedimentation pond 3 are connected in sequence by a sewage pipe 9, so that the manure and sewage can be discharged to the next device according to the set path of the sewage pipe 9.

[0035] The high-moisture manure separated from pond 1 is preferentially discharged to transfer pond 2 for centralized sedimentation. Once a certain amount has accumulated, it is then discharged to sedimentation pond 3 for further sedimentation and concentration. This improves the efficiency of manure sedimentation and concentration, enabling efficient manure collection. Furthermore, the manure is discharged without power from pond 1 and transfer pond 2 via a level difference. Only after a certain amount of manure has accumulated in transfer pond 2 is the manure pumped to sedimentation pond 3 using a power pump 21, significantly reducing the frequency of power pump 21 use and thus lowering energy consumption. This manure collection system, when applied to aquaculture systems, enables efficient and low-energy collection of manure, reducing aquaculture costs.

[0036] A switch valve 4 is installed on the pipeline between the breeding pond 1 and the transfer pond 2. The switch valve 4 is an electric valve, a manual valve or a pneumatic valve. The electric valve is electrically connected to the electric control device, and the pneumatic valve is connected to an air compressor 5.

[0037] The switch valve 4 can adjust the opening and closing of the sewage pipe 9 between the breeding pond 1 and the transfer pond 2. When there is little manure in the breeding pond 1, the switch valve 4 can be closed to prevent manure from being discharged from the breeding pond 1. When the manure in the breeding pond 1 accumulates to a certain amount, the switch valve 4 can be opened to use the liquid level difference to discharge the manure from the breeding pond 1 to the transfer pond 2 without power through the sewage pipe 9. This helps to improve the efficiency of centralized sedimentation and treatment of manure in the transfer pond 2.

[0038] The selection of switch valve 4 depends on the requirements. If switch valve 4 is an electric valve, its opening and closing are controlled by an electronic control device. If switch valve 4 is a manual valve, its opening and closing are achieved through manual operation. Figure 1 The diagram shows a pneumatic valve equipped with an air compressor 5, which provides high-pressure air to the pneumatic valve to achieve its opening and closing.

[0039] Regarding aquaculture pond 1, the water in which aquatic organisms are cultured needs to have a certain oxygen content to ensure the normal needs of the aquatic organisms. When the oxygen content in aquaculture pond 1 is insufficient, it is necessary to add oxygen to the pond. Therefore, aerator 6 is connected to aquaculture pond 1 to increase the oxygen content of the water. A dissolved oxygen meter 11 is also installed in aquaculture pond 1. The dissolved oxygen meter 11 is used to measure the oxygen content of the water in aquaculture pond 1. When the oxygen content is low, aerator 6 can be used to add oxygen to the water in aquaculture pond 1. The dissolved oxygen meter 11 can be directly installed in aquaculture pond 1 for real-time monitoring of the oxygen content of the water. The dissolved oxygen meter 11 can also be a portable device, allowing for the selection of time to measure the oxygen content of the water in aquaculture pond 1. The specific settings depend on actual needs.

[0040] A gas flow meter 61 and a shut-off valve 62 are installed on the pipeline between the aerator 6 and the aquaculture pond 1. The shut-off valve 62 allows for the opening and closing of the pipeline between the aerator 6 and the aquaculture pond 1. When oxygen is needed, the aerator 6 is turned on, and the pressure of the oxygen opens the shut-off valve 62, allowing oxygen to flow to the aquaculture pond 1. When the aerator 6 is turned off, the shut-off valve 62 closes, preventing oxygen from flowing to the aquaculture pond 1 and also preventing backflow of water into the pond. The gas flow meter 61 is used to regulate the oxygen flow rate, ensuring an appropriate oxygen supply to the aquaculture pond 1. This avoids insufficient oxygen supply due to a slow flow rate, which could negatively impact aquatic growth, and also prevents excessive oxygen supply due to a fast flow rate, which could lead to gas bubble disease and other health problems in the aquatic organisms.

[0041] Combination Figure 2 and Figure 3 The aquaculture pond 1 includes a pond body 12 and an air lifting device 13. The air lifting device 13 includes a water inlet pipe 131, an air inlet pipe 132, and an oxygen mixing pipe 133. One end of the water inlet pipe 131 and one end of the air inlet pipe 132 are both connected to one end of the oxygen mixing pipe 133. The other end of the water inlet pipe 131 is connected to the water inlet of the aquaculture pond 1. The other end of the air inlet pipe 132 is connected to the aerator 6. The other end of the oxygen mixing pipe 133 is connected to the pond body 12.

[0042] The water entering the aquaculture pond 1 flows into the oxygen mixing pipe 133 through the water inlet pipe 131. At the same time, the aerator 6 provides oxygen to flow into the oxygen mixing pipe 133 through the air inlet pipe 132. The oxygen and the water are mixed in the oxygen mixing pipe 133, thereby supplementing dissolved oxygen into the aquaculture pond 1 for the convenience of aquaculture.

[0043] A check valve is installed inside the oxygen mixing pipe 133 to prevent backflow of water inside the oxygen mixing pipe 133.

[0044] Regarding the transfer tank 2, a power pump 21 is used to pump the sewage into the sedimentation tank 3. The power pump 21 can be a hydraulic pump, an electric pump, etc. In this invention, the power pump 21 is a hydraulic pump, combined with... Figure 4The power pump 21 is located inside the transfer tank 2 and is suspended at the bottom of the transfer tank 2. The location of the power pump 21 at the bottom of the transfer tank 2 facilitates the extraction of sewage, and the suspension arrangement of the power pump 21, due to its large weight, can prevent damage to the bottom of the transfer tank 2.

[0045] The power pump 21 is suspended at the bottom of the transfer tank 2 by a fixing structure. One end of the fixing structure is fixedly connected to the power pump 21, and the other end is fixedly connected to the top of the transfer tank 2. The fixing structure includes a fixing rod 22, a rope, or a chain. The fixing structure facilitates the removal of the power pump 21 from the transfer tank 2 for maintenance or replacement. The fixing structure can be at least one of the following: fixing rod 22, rope, chain, etc., as long as it can stably fix the power pump 21.

[0046] When the fixing structure is a fixing rod 22, the fixing rod 22 may have a horizontal bar to fix it to the top of the transfer pool 2, and the fixing rod 22 may also have a vertical bar to extend to the bottom of the pool to fix the power pump 21. When the fixing structure is a rope or chain, multiple ropes or chains may be symmetrically arranged to ensure the stability of the power pump 21.

[0047] In addition to the above structure, combined with Figure 5 The sedimentation tank 3 is connected to a resource recovery device 7 for the resource recovery treatment of fecal waste. The resource recovery device 7 includes an anaerobic device 71, and / or an ecological ditch 72, and / or an algae cultivation pond, and / or a biological filter, and / or aerobic equipment. Aquatic plants and / or aquatic products are cultivated in the ecological ditch 72 and the biological filter.

[0048] The breeding pond 1, transfer pond 2, sedimentation pond 3, and resource recovery device 7 are connected sequentially by a sewage pipe 9. A sewage pump 8 is installed between the sedimentation pond 3 and the resource recovery device 7. The sewage pump 8 can be any type of hydraulic pump, electric pump, etc. After the manure is separated in the breeding pond 1, it is discharged to the transfer pond 2 for centralized sedimentation using the liquid level difference. Then, the manure is pumped to the sedimentation pond 3 for sedimentation and concentration using a power pump 21. Finally, the manure is pumped to the resource recovery device 7 for resource recovery treatment using the sewage pump 8, thereby avoiding the discharge of manure into the environment.

[0049] Resource recovery includes, but is not limited to, the following:

[0050] If the sedimentation tank 3 produces a large amount of concentrated manure, it can be discharged to the anaerobic device 71, where anaerobic microorganisms decompose organic matter to produce biogas, which can be used for power generation or directly as an energy source. The remaining biogas slurry and biogas residue can be further processed into organic fertilizer.

[0051] If the sedimentation tank 3 produces relatively little concentrated manure, it can be directly discharged into the ecological ditch 72. By cultivating aquatic plants, aquatic organisms, and microorganisms in the ecological ditch 72, the nutrients in the manure can be fully utilized, allowing byproducts such as aquatic plants and aquatic organisms to be produced and sold, thereby increasing production and income and reducing aquaculture costs. Furthermore, the consumption of nutrients reduces the levels of ammonia nitrogen and nitrite in the ecological ditch 72, achieving purification and preventing environmental pollution.

[0052] After sedimentation and concentration in sedimentation tank 3, the manure is mixed with conditioners such as straw and sawdust to adjust the carbon-nitrogen ratio and moisture content. The mixture is then piled into strips or heaps and turned regularly to ensure sufficient oxygen. This allows aerobic microorganisms to decompose organic matter, forming organic fertilizer rich in organic matter, nitrogen, phosphorus, potassium and other nutrients, which can be used for agricultural planting.

[0053] After sedimentation and concentration in sedimentation tank 3, the fecal waste can be introduced into the biological filter. Microorganisms and plant roots in the biological filter absorb and decompose the nutrients in the fecal waste to obtain purified water for recycling.

[0054] After sedimentation and concentration in sedimentation tank 3, the manure can be mixed with an appropriate amount of leaf mold, straw and other conditioning agents to create a suitable environment for earthworm growth. The mixture is then placed in the earthworm composting bin, where earthworms can decompose the manure to produce earthworm castings rich in organic matter.

[0055] After sedimentation and concentration in sedimentation tank 3, the fecal waste is introduced into an algae cultivation tank. The algae absorb nutrients such as nitrogen and phosphorus for photosynthesis, which not only reduces the pollution of the environment by the fecal wastewater, but also allows the algae to be harvested as high-protein feed or bioenergy raw materials.

[0056] The above-mentioned resource utilization methods can be used in two or more ways at the same time to make full use of manure for resource utilization, which not only protects the environment, but also can be used for the production and sale of by-products to increase income.

[0057] Based on this, the above-mentioned manure collection system can be used in aquaculture systems to efficiently collect and recycle manure generated by aquaculture systems. This not only ensures a good aquaculture environment but also avoids environmental pollution. At the same time, it can reduce aquaculture costs and even increase output benefits through the sale of by-products such as biogas, aquatic products, and algae. It is suitable for large-scale promotion.

[0058] As for aquaculture systems, they can be industrialized using water bodies such as rivers, lakes, reservoirs, waterways, marshes, low-lying areas, lakes, fishponds, and ponds, or they can be carried out in actual factory workshops or other types of aquaculture systems. All of these can achieve efficient and low-energy collection and resource-based treatment of manure and waste through manure collection systems, so as to protect the environment and reduce aquaculture costs.

[0059] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
