Description

Technical Field

[0001] The invention relates to the technical field of marine shellfish culture, in particular to a fluidized bed for cultivating young sea clams. Background Art

[0002] Coelomactra antiquata belongs to the phylum Mollusca, class Bivalvia, order Cercophoridae, and family Clamidae. It is commonly known as "royal concubine clam" or "sea clam". They are widely distributed in the coastal areas of the western Pacific Ocean, including Japan, North Korea, South Korea, the coast of China, and the Indian Peninsula, especially in Fujian and eastern Guangdong in China, where resources are abundant. Coelomactra antiquata mainly inhabits sandy beaches about 20 meters deep from the intertidal zone to the subtidal zone. It is a shallow-sea buried bivalve. Due to its tender meat, delicious taste, and rich in high-quality protein, vitamins and minerals, Coelomactra antiquata has become an ideal choice for many food lovers and those who pursue healthy eating. It has significant economic potential and is highly favored by the market.

[0003] As people's demand for healthy diets continues to increase, the market prospects for sashimi are becoming increasingly broad. However, the accompanying overfishing problem is becoming increasingly serious, which has caused obvious damage to sashimi resources, and the resources in many habitats are close to exhaustion. Overfishing not only disrupts the local ecological balance, but also threatens the long-term survival of species, leading to the degradation of ecosystems and the reduction of biodiversity. Therefore, how to protect existing resources and supplement wild resources through sustainable breeding methods has become a key issue that needs to be solved urgently.

[0004] Traditional artificial seedling raising methods are usually carried out in indoor seedling ponds or cement pools. However, due to the high requirements of water quality and bottom environment for the scallops, the survival rate of juvenile spat is generally low, and the yield of seedling raising is also unstable. The sensitivity of the scallops to the cleanliness of the water, oxygen content and benthic conditions makes it difficult for traditional seedling raising methods to effectively meet its growth needs. Therefore, the development of more advanced seedling raising technology is the key to improving the survival rate of seedlings and optimizing aquaculture benefits. Summary of the invention

[0033] As in the background technology, Coelomactra antiquata belongs to the phylum Mollusca, class Bivalvia, order Curculigo, family Clamidae, commonly known as "royal concubine mussel" or "sea mussel". They are widely distributed in the coastal areas of the western Pacific Ocean, including Japan, North Korea, South Korea, coastal China and the Indian Peninsula, especially in Fujian and eastern Guangdong in China. Coelomactra antiquata mainly inhabits the sandy beaches from the intertidal zone to the subtidal zone about 20 meters deep, and belongs to the shallow sea buried bivalve. Because of its tender meat, delicious taste, and rich in high-quality protein, vitamins and minerals, Coelomactra antiquata has become the ideal choice for many food lovers and those who pursue healthy diets, and has significant economic potential and is favored by the market.

[0034] As people's demand for healthy diets continues to increase, the market prospects for sashimi are becoming increasingly broad. However, the accompanying overfishing problem is becoming increasingly serious, which has caused obvious damage to sashimi resources, and the resources in many habitats are close to exhaustion. Overfishing not only disrupts the local ecological balance, but also threatens the long-term survival of species, leading to the degradation of ecosystems and the reduction of biodiversity. Therefore, how to protect existing resources and supplement wild resources through sustainable breeding methods has become a key issue that needs to be solved urgently.

[0035] Traditional artificial seedling raising methods are usually carried out in indoor seedling ponds or cement pools. However, due to the high requirements of water quality and bottom environment for the scallops, the survival rate of juvenile spat is generally low, and the yield of seedling raising is also unstable. The sensitivity of the scallops to the cleanliness of the water, oxygen content and benthic conditions makes it difficult for traditional seedling raising methods to effectively meet its growth needs. Therefore, the development of more advanced seedling raising technology is the key to improving the survival rate of seedlings and optimizing aquaculture benefits.

[0036] In order to improve the above problems, the present application proposes a fluidized bed for the cultivation of young sea clams. The fluidized bed technology maintains the fluidity of the sand layer and the stability of the water quality through continuous water flow, providing a good growth environment for young sea clams. The continuous circulation of water flow not only increases the dissolved oxygen content in the water body, ensuring that the young sea clams can obtain sufficient oxygen, but also effectively removes metabolic waste and reduces the risk of water quality deterioration and accumulation of harmful substances. In addition, the fluidized bed technology can also achieve precise environmental regulation and flexibly adjust the speed and direction of the water flow to meet the needs of different growth stages. The dynamic water environment of the fluidized bed technology can optimize the living conditions of young sea clams and greatly improve their survival rate and growth rate. Compared with the traditional static seedling method, the fluidized bed technology shows significant advantages in improving the breeding efficiency and environmental friendliness of young sea clams. In addition, the technology keeps the bottom loose and avoids the deposition of harmful substances by reasonably controlling the fluidity and shear force of the water flow, further reducing the risk of disease. In general, the western tongue seedling device based on the fluidized bed technology provides an efficient, stable and sustainable solution for the cultivation of young sea clams. This technology not only overcomes many limitations of traditional aquaculture methods, but also promotes the development of marine shellfish aquaculture towards a more intelligent, automated and environmentally friendly direction. In the future, with the further development of technology and the expansion of its application scope, fluidized bed technology is expected to become a key cultivation method in the sea clam aquaculture industry, which can not only increase production, but also effectively protect natural resources, achieving a win-win situation of ecological aquaculture and economic benefits.

[0037] See also Figure 1 As shown, a fluidized bed for cultivating young clams according to an embodiment of the present application includes:

[0038] A cultivation pool 1, wherein the top of the cultivation pool 1 is provided with an opening, the cultivation pool 1 is provided with a water inlet and a water outlet, and a sand layer 2 and a filler layer 3 are provided in the cultivation pool 1;

[0039] The supporting assembly is arranged at the bottom of the cultivation pool 1 .

[0040] In some specific embodiments, the water inlet comprises:

[0041] The upper water inlet 4 is arranged at the top of the left side of the cultivation tank 1, and the upper water inlet 4 and the top opening of the cultivation tank 1 are on the same horizontal line;

[0042] The lower water inlet 5 is arranged at the bottom of the left side of the cultivation tank 1 .

[0045] The upper water outlet 6 is arranged on the right side of the top of the cultivation tank 1;

[0046] The lower water outlet 7 is arranged at the bottom of the cultivation pool 1 .

[0047] In some specific embodiments, the position of the upper water outlet 6 is lower than the position of the top opening of the cultivation tank 1 .

[0048] Specifically, the fluidized bed system provides a stable and suitable growth environment for young sea clams by simulating the natural environment. This helps to reduce deaths caused by environmental changes or discomfort, thereby increasing the survival rate of young sea clams. In the fluidized bed system, the water body can maintain constant renewal and circulation to ensure clean water quality while providing sufficient oxygen and nutrients. This helps to accelerate the growth rate of young sea clams and enable them to reach maturity faster. The structural design of the fluidized bed system makes it easy to install, operate and maintain. The support components are located at the bottom of the culture tank to facilitate the fixation and support of the entire system, and the positions of the water inlet and outlet are also carefully designed to ensure smooth and even distribution of water flow. This design simplifies daily management and maintenance work, reducing labor intensity and cost. The fluidized bed system can be adjusted and optimized according to actual needs. For example, the water flow rate and water quality conditions can be adjusted by changing the type and thickness of the filler layer to meet the needs of young sea clams at different growth stages. In addition, the system can be combined with other aquaculture equipment and technologies to form a more complete aquaculture system. The fluidized bed system is usually made of environmentally friendly materials, which is environmentally friendly and recyclable. At the same time, the system reduces dependence on and consumption of natural resources by increasing the survival rate and growth rate of young sea clams, helping to achieve sustainable development goals. Since the fluidized bed system can increase the survival rate and growth rate of young sea clams, it can shorten the breeding cycle and increase production. This helps to reduce breeding costs and improve economic benefits. In addition, high-quality sea clams products can also meet market demand and enhance brand image.

[0049] The upper water inlet 4 is arranged at the top of the left side of the cultivation pool 1, and is at the same level as the top opening of the cultivation pool 1. Such a design helps to reduce the disturbance of the water flow to the environment in the pool, and is convenient for observation and maintenance. As the main water inlet channel, the upper water inlet 4 is responsible for introducing fresh water into the cultivation pool to provide the necessary water quality conditions for the young sea clams. The lower water inlet 5 is arranged at the bottom of the left side of the cultivation pool 1. It is connected with the upper water inlet 4 through a pipeline to form a circulating water flow to ensure the uniform distribution and renewal of the water body. The lower water inlet 5 serves as an auxiliary water inlet channel and works together with the upper water inlet to maintain the stability and cleanliness of the water body in the cultivation pool. The upper water outlet 6 is arranged on the right side of the top of the cultivation pool 1. Its position is lower than the position of the top opening of the cultivation pool 1, which helps to control the water level and prevent the water body from overflowing. The upper water outlet 6 is responsible for discharging the treated wastewater from the cultivation pool to maintain the cleanliness and suitability of the water quality. The lower water outlet 7 is arranged at the bottom of the cultivation pool 1. It is used in conjunction with the upper water outlet 6 to form an effective drainage system to ensure that excess water can be discharged in time. The lower water outlet 7 serves as the main drainage channel and works together with the upper water outlet to maintain the stability of the water level in the cultivation pool and the excellent water quality.

[0050] The pipeline can be:

[0051] Polyvinyl chloride (PVC) pipes, PVC pipes have good corrosion resistance and chemical resistance, easy to install and maintain. Its cost is relatively low and suitable for a variety of environmental conditions. However, PVC pipes may deform at high temperatures and are not suitable for conveying hot water.

[0052] Polypropylene (PP) pipes, PP pipes have excellent corrosion resistance and high temperature resistance, suitable for conveying hot water and chemicals. Its light weight makes it easy to carry and install. The non-toxic properties of PP pipes make them suitable for the food industry and medical systems.

[0053] High-density polyethylene (HDPE) pipes, HDPE pipes have high strength and toughness, and can withstand certain pressure and impact. It has good corrosion resistance and wear resistance, and is suitable for underground burial and long-distance transportation. The flexibility of HDPE pipes gives it an advantage in earthquake-prone areas.

[0054] Structured Wall HDPE pipes, which have enhanced strength and rigidity through special design, are suitable for occasions requiring higher load-bearing capacity. Its structural design provides better pressure resistance and durability, and is widely used in municipal engineering and industrial drainage systems.

[0055] Solid Wall High Density Polyethylene (Solid Wall HDPE) Pipe Solid wall HDPE pipe has uniform wall thickness and provides good sealing performance. It is suitable for occasions that require strict sealing requirements, such as drinking water transportation and gas transportation. The corrosion resistance and aging resistance of solid wall HDPE pipe ensure the stability of long-term use.

[0056] In some specific embodiments, the support assembly includes:

[0057] A support plate 8, wherein the outer diameter of the support plate 8 matches the inner diameter of the cultivation tank 1, the side wall of the support plate 8 is fixedly connected to the inner wall of the cultivation tank 1, a mesh pad 9 is laid on the top of the support plate 8, a filler layer 3 is laid on the top of the mesh pad 9, and a sand layer 2 is laid on the top of the filler layer 3;

[0058] The support columns 10 are provided in plurality, and the plurality of support columns 10 are all provided at the bottom of the support plate 8, and the plurality of support columns 10 are vertically provided, and the tops and bottoms of the plurality of support columns 10 are fixedly connected to the bottom of the support plate 8 and the inner bottom wall of the cultivation pool 1 respectively.

[0059] Specifically, the support plate 8 is located at the bottom of the culture tank 1, and its outer diameter matches the inner diameter of the culture tank 1 to ensure stability and sealing. The side wall of the support plate 8 is fixedly connected to the inner wall of the culture tank 1 to provide structural support. A mesh pad 9 is laid on the top of the support plate 8, which allows water to pass but prevents sand or other fillers from flowing out. The support plate is usually made of corrosion-resistant materials, such as stainless steel or specially treated plastics to resist the environmental effects of long-term immersion in water. The mesh pad 9 is laid on the top of the support plate 8, which provides a platform that is permeable to water but not permeable to sand or other fillers. This design helps to maintain the continuity of the water flow while preventing the loss of the underlying material. The material of the mesh pad 9 is usually a synthetic fiber or metal mesh that is wear-resistant and not easy to clog, and these materials can withstand the impact of the water flow without deformation. The filler layer 3 is laid on the top of the mesh pad 9 to provide additional growth matrix and habitat for the young sea clams. The choice of filler can be adjusted according to specific cultivation needs, such as using anthracite, shell powder or other suitable materials. The packing layer not only provides physical support, but also helps to simulate the natural environment and promote the natural growth of juvenile sea clams. The packing material should have good biocompatibility and stability. The sand layer 2 is laid on top of the packing layer 3 to further simulate the natural living environment of clams. The thickness and texture of the sand layer can be adjusted according to the type and growth stage of the juvenile sea clams. The sand layer provides a soft substrate, which helps to protect the juvenile sea clams from damage by hard objects and provides a comfortable habitat. The size and shape of the sand particles should be suitable for the activity habits of the clams. There are multiple support columns 10, which are evenly distributed at the bottom of the support plate 8 and are vertically arranged. The top and bottom of the support column 10 are fixedly connected to the bottom of the support plate 8 and the inner bottom wall of the cultivation tank 1 respectively to enhance the stability of the entire structure. As the main load-bearing structure, the support column 10 ensures that the weight of the upper filler and the sand layer is evenly distributed, and prevents the support plate 8 from sinking or deforming. The support column is usually made of strong and durable materials, such as reinforced concrete or heavy plastic.

[0060] In some specific embodiments, the axial cross-section of the bottom of the cultivation tank 1 is an inverted isosceles triangle structure.

[0061] In some specific embodiments, the connection point between the lower water outlet 7 and the cultivation pool 1 coincides with the axis of the cultivation pool 1 .

[0062] In some specific embodiments, the upper water inlet 4, the lower water inlet 5, the upper water outlet 6, and the lower water outlet 7 are all provided with valves.

[0063] Specifically, the valve may be:

[0064] Ball valve, which can be opened and closed by rotating 90°, has the advantages of small fluid resistance, simple structure, small size and light weight. In the process of cultivating young clams, ball valves can be used in occasions that require rapid opening and closing, such as emergency water flow cut-off or water flow regulation.

[0065] Gate valves open or cut off the flow of media in the pipeline by lifting the gate plate. They have good fluid control characteristics and low pressure loss. In the inlet and outlet pipes of the aquaculture pond, gate valves can be used to control the flow of water to ensure the stability of the aquaculture environment.

[0066] Butterfly valve is a simple regulating valve consisting of a short tube and a disc. It can open or close the water flow by rotating the disc and has good flow control characteristics. In the process of cultivating young clams, butterfly valves can be used in occasions where water flow needs to be adjusted frequently, such as adjusting the water level or water quality of the breeding pond.

[0067] Check valve, a check valve is an automatic valve that prevents the backflow of the medium. When the system pressure exceeds the set value, it automatically opens to release the excess pressure. In the aquaculture system, the check valve can be used to prevent the reverse flow of water and protect the water pump and other equipment from damage.

[0068] Safety valve, a valve that automatically opens to release excess pressure when the system pressure exceeds the set value. In the process of cultivating young clams, the safety valve can be used to maintain the pressure stability in the aquaculture system to prevent equipment damage or deterioration of the aquaculture environment due to excessive pressure.

[0069] Solenoid valve is an automatic valve that drives the valve to open and close through the magnetic field generated by the electromagnetic coil. It has the advantages of fast response speed and high precision. In the sea clam juvenile cultivation system with a high degree of automation, the solenoid valve can be used in conjunction with the automatic control system to achieve precise adjustment of the working conditions.

[0070] In summary, the selection and use of these valves should be determined according to the specific farming environment and needs. For example, in situations where precise control of water flow is required, a solenoid valve may be selected; while in situations where reverse flow of water is required, a check valve may be selected. At the same time, the performance, reliability and compatibility of the valve with the system are also important factors to consider when selecting a valve.

[0071] In some specific embodiments, a plurality of oxygen-enhancing stones 11 are suspended in the cultivation pond 1 .
