Description

Technical Field

[0001] This invention relates to an integrated multi-layer aquaculture ventilation device with switchable ventilation modes, belonging to the field of insect aquaculture equipment. Background Technology

[0002] Insect farming is a high-yield and cost-effective industry. Insects have short growth cycles, high reproductive capacity, and high feed conversion rates. Compared with traditional animal husbandry, insect farming has a smaller carbon footprint and less environmental impact. Insect farming can reduce greenhouse gas emissions and mitigate climate change; protect biodiversity, reduce deforestation and land degradation; and produce organic fertilizer, improving soil quality. The application of artificial intelligence and automation technologies is making insect farming more efficient and automated. Application No.: 202510903415.8, Invention Title: A partitioned continuous farming mechanism and its farming system, comprising an automatic material loading and unloading mechanism, a farming layer, and an environmental control mechanism; the side plate and two automatic doors contact the automatic material loading and unloading mechanism to form a farming space, which is divided into at least two farming zones, each of which is equipped with an environmental control mechanism, and at least one farming zone is equipped with a material loosening mechanism; at least one farming zone has automatic doors at both ends. This invention breaks away from the traditional one-time, whole-system feeding method of insect and plant breeding. It divides the breeding space into several breeding zones, allowing for precise control of each zone based on the different environmental and material needs of insects and plants at different growth stages. This provides more suitable growth conditions, shortens the breeding cycle, and improves the growth rate and quality of insects and plants. However, each zone in this equipment has its own separate ventilation system, resulting in high equipment costs and complex maintenance. Furthermore, during insect breeding, the incoming air is typically discharged directly through the outlet, sometimes resulting in high-temperature exhaust air and low energy efficiency. Summary of the Invention

[0003] This invention provides an integrated multi-layer aquaculture ventilation device with switchable ventilation modes, which solves the problems of existing multi-layer three-dimensional insect aquaculture ventilation equipment being separate, costly, and complex to maintain, as well as the problem of energy waste caused by the direct emission of exhaust gas in existing ventilation equipment.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: An integrated multi-layer aquaculture ventilation device with switchable ventilation modes, comprising an air inlet mechanism and / or an air outlet mechanism. The air intake mechanism includes an air intake duct, which is fixedly installed on the air intake side column. One side of the air intake duct is open to form a main ventilation channel, while the other sides are sealed to the breeding frame. The bottom of the air intake duct is provided with an air intake hole. The air intake duct is provided with an air adjustment mechanism on the open side. The air adjustment mechanism can adjust the position of its air guide component to switch between two working modes: during breeding operations, a horizontal ventilation mode is achieved by the airflow flowing horizontally along the breeding layer; during material drying, a vertical penetration ventilation mode is achieved by the airflow penetrating the breeding layer. The air outlet mechanism includes an air outlet duct, which is fixedly installed on the air outlet side column. One side of the air outlet duct is open to form a ventilation channel, and the other sides are sealed and connected to the insect breeding frame. An air outlet hole is provided at the top of the air outlet duct. The air outlet side column is arranged along the length of the air outlet duct. Each air outlet side column includes an airflow circulation mechanism. The airflow circulation mechanism can draw the air from the upper air outlet to the bottom and then blow it into the air inlet duct to form an internal circulation within the duct. At the same time, the air in the air inlet duct moves horizontally towards the air outlet duct under the action of the airflow circulation mechanism, so that the air moves horizontally within the breeding layer.

[0005] Furthermore, preferably: the air conditioning mechanism includes a flexible damper plate, a damper connecting rod, and a moving power mechanism; the moving power mechanism is mounted on the air inlet side column and connected to the flexible damper plate via the damper connecting rod; the air inlet side column has a moving groove for the damper connecting rod to move up and down; the flexible damper plate has several sets of ventilation holes, each set of ventilation holes is arranged vertically at intervals, and the spacing is adapted to the position of the penetrating air plate of the aquaculture layer; when the moving power mechanism drives the damper connecting rod to move along the moving groove, the flexible damper plate drives the ventilation holes to move up and down synchronously, thereby changing the position of the ventilation holes relative to the penetrating air plate: under aquaculture conditions, the ventilation holes are adjusted to align with the aquaculture layer, so that the airflow flows horizontally to achieve horizontal ventilation; under drying conditions, the ventilation holes are moved to align with the gap between the penetrating air plates, so that the airflow penetrates the aquaculture layer vertically to achieve penetrating ventilation.

[0006] Furthermore, preferably: the area of ​​the ventilation holes in the several groups increases sequentially from top to bottom.

[0007] Furthermore, preferably, the bottom of the flexible damper plate is provided with a counterweight mechanism.

[0008] Furthermore, preferably: the airflow circulation mechanism includes a sealed box, on the inward side of the sealed box are several sets of ventilation mechanisms, the bottom of the sealed box is equipped with feet, the bottom of the sealed box is equipped with a crossflow fan, the air outlet of the crossflow fan is located in the lowest space of the breeding equipment and is not connected to the air outlet duct, and the air outlet of the crossflow fan is equipped with an automatic door.

[0009] Furthermore, preferably: the area of ​​the air vents in several groups of the ventilation mechanisms decreases sequentially from top to bottom. An integrated multi-layer aquaculture ventilation device with switchable ventilation modes.

[0010] Furthermore, preferably: a drying air outlet is provided at the bottom of the air outlet duct, and the drying air outlet is located at the bottom layer of the breeding equipment and is not connected to the ventilation duct.

[0011] The beneficial effects of this invention are: The device of this invention integrates the air intake mechanism and the air outlet mechanism into a single unit and directly seals and connects to the aquaculture frame. This integrated design avoids the need to purchase and install multiple independent fans, pipes and control systems for functions such as air intake, air outlet and circulation, which greatly reduces the initial investment of the equipment, the amount of materials used and the complexity and time of on-site installation.

[0012] The airflow circulation mechanism of this invention actively extracts and mixes the exhaust gas (usually carrying residual heat and a certain amount of humidity) discharged from the upper air outlet back to the bottom, and sends it back into the air inlet to participate in the circulation. In the breeding season when heat preservation is required, the recovery of the residual heat of the exhaust gas can significantly reduce the energy consumption for heating the fresh air; in the environment where humidity control is required, the recovery of some humidity can reduce the energy consumption for humidification, directly reducing the overall energy consumption of the system and solving the energy waste problem of traditional direct discharge systems.

[0013] The ventilation mode of this invention is adjustable: by switching between horizontal ventilation (suitable for uniform oxygen supply and heat dissipation) and vertical penetration ventilation (suitable for rapid drying and thorough air exchange) modes through the air adjustment mechanism, a single device can adapt to the needs of different process stages such as insect breeding and material drying, avoiding the need to configure dedicated ventilation equipment for different functions and further reducing costs.

[0014] The horizontal ventilation mode of this invention helps to create a uniform airflow distribution on each layer of the aquaculture surface, avoiding localized hypoxia or uneven temperature and humidity; the vertical penetration mode can effectively penetrate the material layer, improving drying or gas exchange efficiency. The precise control of these two modes fundamentally improves the aquaculture effect, indirectly increasing production efficiency.

[0015] This invention, through the integrated physical structure and intelligent circulation design of airflow organization, not only directly solves the problems of high cost and difficult maintenance caused by split equipment, but also effectively overcomes the pain point of energy waste in traditional ventilation by internal circulation of exhaust gas energy. At the same time, it increases the flexibility of ventilation mode, making it an innovative design that combines economy, energy saving and high efficiency. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are also described.

[0019] Example 1 like Figure 1-9 As shown, an integrated multi-layer aquaculture ventilation device with switchable ventilation modes includes an air inlet mechanism and / or an air outlet mechanism. The air intake mechanism includes an air intake duct 1, which is fixedly installed on the air intake side column 3. One side of the air intake duct 1 is open to form a main ventilation channel, while the other sides are sealed and connected to the breeding frame. An air intake hole is provided at the bottom of the air intake duct 1. An air intake valve can be installed at the location of the air intake hole to control the air intake, or it can be omitted and set as needed. The entire air intake duct 1 can be provided with air intake holes, or only some parts can have air intake holes. This embodiment uses air intake holes throughout.

[0020] The air inlet duct 1 is equipped with an air adjustment mechanism on the open side. The air adjustment mechanism can adjust the position of its air guide component to switch between two working modes: during aquaculture operations, a horizontal ventilation mode is achieved by the airflow flowing horizontally along the aquaculture layer; during material drying, a vertical penetration ventilation mode is achieved by the airflow penetrating the aquaculture layer. The specific structure of the air conditioning mechanism can be selected based on its corresponding function, using equipment capable of changing the position of the air inlet holes. The structure used in this embodiment is as follows: The air conditioning mechanism includes a flexible damper plate 4, a damper connecting rod 5, and a moving power mechanism 7; the moving power mechanism 7 is mounted on the air inlet side column 3 and connected to the flexible damper plate 4 via the damper connecting rod 5; the air inlet side column 3 has a moving groove 8 for the damper connecting rod 5 to move up and down; the flexible damper plate 4 has several sets of ventilation holes 6, arranged vertically at intervals, with the spacing adapted to the position of the penetrating air plate 16 in the aquaculture layer; when the moving power mechanism 7 drives the damper connecting rod 5 to move along the moving groove 8, the flexible damper plate 4 drives the ventilation holes 6 to rise and fall synchronously, thereby changing the position of the ventilation holes 6 relative to the penetrating air plate 16: under aquaculture conditions, the ventilation holes are adjusted to align with the aquaculture layer, allowing airflow to flow horizontally for horizontal ventilation; under drying conditions, the ventilation holes move to align with the gap between the penetrating air plates 16, allowing airflow to penetrate the aquaculture layer vertically for penetrating ventilation.

[0021] The flexible damper plate 4 is generally made of soft, windproof, and corrosion-resistant materials. A counterweight can be installed at the bottom of the flexible damper plate 4 to improve its sealing performance.

[0022] The number of ventilation holes is determined by the number of breeding layers, generally one set of ventilation holes per layer. Each set consists of multiple air holes on the air inlet panel. The ventilation area of ​​the air holes varies in different sets, and generally, the area of ​​the air holes increases from top to bottom. The shape and number of air holes can be selected appropriately according to the needs.

[0023] The air outlet mechanism includes an air outlet duct 9, which is fixedly installed on the air outlet side column. One side of the air outlet duct 9 is open to form a ventilation channel, and the other sides are sealed and connected to the insect breeding frame.

[0024] The top of the air outlet duct 9 is provided with an air outlet hole, which is connected to the fan 15. The fan 15 is equipped with an air valve. The air outlet side columns are arranged along the length of the interior of the air outlet duct 9. Each air outlet side column includes an airflow circulation mechanism. The airflow circulation mechanism can draw the air that should flow out from the upper air outlet 17 to the bottom and then blow it towards the air inlet duct 1, forming an internal circulation within the duct. At the same time, the air in the air inlet duct 1 moves horizontally towards the air outlet duct 9 under the action of the airflow circulation mechanism, so that the air moves horizontally within the breeding layer. Any device that can achieve the above functions can be used as the airflow circulation mechanism of this patent.

[0025] The scheme adopted in this embodiment is as follows: the airflow circulation mechanism includes a sealed box 10, and a number of ventilation mechanisms 11 are provided on the inward side of the sealed box 10. The ventilation mechanism 11 consists of a number of air holes opened on the sealed box 10. The number of air holes in each group of ventilation mechanisms 11 is not consistent. Generally, the area of ​​the air holes decreases from top to bottom. A group of ventilation mechanisms 11 is opened on each breeding layer.

[0026] The bottom of the sealed box 10 is equipped with feet 14, and a crossflow fan 12 is installed at the bottom of the sealed box 10. The outlet of the crossflow fan 12 is located in the lowest space of the breeding equipment and is not connected to the air outlet duct 9. The outlet of the crossflow fan 12 is equipped with an automatic door. The automatic door can open when the crossflow fan 12 is working and close when it is not working. Any device with the above function can be used, such as a magnetic door or a spring door. In this embodiment, a sealing cloth or sealing film 13 is used, which is fixed to the upper part of the outlet of the crossflow fan 12. The crossflow fan 12 opens when it is working, under the action of its airflow; when it is not working, it closes under its own weight and the suction force of the fan at the top of the breeding equipment.

[0027] This invention relates to an integrated multi-layer aquaculture ventilation device with switchable ventilation modes. The air inlet and outlet mechanisms can be used independently or in combination with other air inlet and outlet mechanisms. In this embodiment, they are used together.

[0028] The operation process of this embodiment: Black soldier fly larvae and materials are placed on the culture layer, and then the culture operation is carried out.

[0029] Aquaculture ventilation Figure 7 As shown, turn on the top fan and adjust the ventilation holes on the flexible damper plate 4 to align them with the breeding layer. Air enters from the air inlet 2. Under the action of the fan, the air flows from bottom to top in the equipment and flows horizontally from the air inlet side to the air outlet side inside the breeding layer. This helps to form a uniform airflow distribution on each breeding surface and avoid local hypoxia or uneven temperature and humidity.

[0030] Drying and ventilation Figure 8As shown, turn on the top fan and adjust the ventilation holes on the flexible damper plate 4 to align them with the gaps between the penetrating air plates 16. Hot, dry air enters through the air inlet 2. Under the action of the fan, the hot, dry air flows upwards within the equipment. Inside the breeding layer, under the action of the penetrating air plates 16, the hot air flows upwards from the bottom of the breeding layer, penetrating the breeding layer to dry the black soldier fly larvae and materials. The hot, dry air can be provided by a separate air supply system, or it can enter through the drying air inlet 19, be heated by the heat exchange tube 18, and then enter the ventilation duct for drying.

[0031] During the breeding season when heat preservation is required, recovering waste heat from exhaust gases can significantly reduce energy consumption for heating fresh air; ventilation diagram as shown. Figure 9 As shown, with the top fan off, air enters through inlet 2. Driven by the fan, the air flows upwards within the equipment and horizontally from the inlet side to the outlet side inside the breeding layer. This facilitates a uniform airflow distribution on each breeding surface. The air on the outlet side is drawn back to the bottom by the crossflow fan 12, further heated by the heat exchanger, and then enters the ventilation channel, effectively recovering some waste heat and helping to reduce energy consumption, thus solving the energy waste problem of traditional direct exhaust systems. Of course, internal air circulation can also be achieved by closing inlet 2 or reducing the speed of the outlet fan.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
