Description

Technical Field

[0001] This invention relates to an energy-saving ventilation device for a three-dimensional insect breeding platform, belonging to the field of insect breeding equipment. Background Technology

[0002] Three-dimensional insect farming is a highly efficient method of insect breeding. Through multi-layered vertical arrangement, it effectively utilizes space, solving the problems of large land area and high cost associated with traditional ground-based farming. Insect rearing requires suitable temperature and humidity; therefore, ventilation and heat exchange are crucial components of three-dimensional insect farming equipment. Patent publication number CN 117016495 A discloses a method and apparatus for raising corrosive insect larvae using natural ventilation and supplemental lighting. Its specific structure includes: a sealed insect farming device with several farming layers. Each farming layer includes a bottom support mechanism and surrounding baffles. The baffles are perforated and breathable, and a sealing mechanism is provided around each baffle. This sealing mechanism can be opened or closed depending on the actual farming environment. This invention utilizes the phototaxis of black soldier fly larvae. During the larval rearing process, the larvae are alternately reared under light and dark conditions, according to environmental requirements. Under light, the larvae, attracted to light, move downwards from the surface of the culture medium to avoid sunlight. When there is no light, the larvae return to the surface, creating small pores in the medium for ventilation. This not only loosens the medium, preventing it from clumping, but also facilitates ventilation and heat dissipation, effectively preventing medium deterioration. However, the following problem exists: air flows horizontally within the same rearing layer, driven by wind speed. Therefore, airflow velocity plays a decisive role in the ventilation and heat exchange of the device, resulting in generally limited ventilation and heat exchange efficiency. It needs to be used in conjunction with a fan to achieve good ventilation and heat exchange effects. Summary of the Invention

[0003] This invention provides an energy-saving ventilation device for a three-dimensional multi-layer aquaculture platform, which solves the problems of high ventilation energy consumption, poor ventilation heat exchange effect and complex structure of existing three-dimensional multi-layer aquaculture platforms.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0005] An energy-saving ventilation device for a three-dimensional multi-layer aquaculture platform includes an air outlet mechanism and / or an air inlet mechanism;

[0006] The air intake mechanism includes a main air intake that is installed on the side of the three-dimensional multi-layer aquaculture platform and sealed to the side, and the air intake is provided with several air intake pipes in different positions.

[0007] The air outlet mechanism is located on the other side of the three-dimensional multi-layer aquaculture platform and is sealed to the main air outlet on the side. An air outlet pipe is provided on the air outlet.

[0008] The air outlet pipe is located at the top of the three-dimensional multi-layer aquaculture platform, and the position of the air outlet pipe is higher than the three-dimensional multi-layer aquaculture platform;

[0009] Air circulates in the transverse ventilation duct between the two adjacent aquaculture platforms.

[0010] Furthermore, preferably, the main air inlet and the main air outlet are an integral structure that completely covers the sides of the three-dimensional multi-layer aquaculture platform.

[0011] Furthermore, preferably: the main air intake includes several small air intakes, and the several small air intakes completely cover the sides of the three-dimensional multi-layer aquaculture platform;

[0012] The main air outlet includes several smaller air outlets, which completely cover the other side of the three-dimensional multi-layer aquaculture platform.

[0013] Furthermore, preferably: the small air inlets or small air outlets are staggered on both sides of the three-dimensional multi-layer aquaculture platform.

[0014] Furthermore, preferably: the main air intake includes an air intake box, which is connected to the transverse ventilation duct of each floor through an air intake duct;

[0015] The main air outlet includes an air outlet box, which is connected to the horizontal ventilation duct of each floor through an air outlet duct.

[0016] Furthermore, preferably, the air outlet pipe is equipped with an air outlet valve and a fan.

[0017] Furthermore, preferably, the air inlet mechanism and the air outlet mechanism are provided with a heat insulation layer.

[0018] Furthermore, preferably: the energy-saving ventilation also includes a waste heat utilization mechanism, and the air inlet pipe and air outlet pipe are connected to the waste heat utilization mechanism.

[0019] Further, preferably: the waste heat utilization mechanism is a waste heat outlet set at the top of the three-dimensional multi-layer aquaculture platform, the air inlet pipe passes through the waste heat outlet, an insulation layer is provided between the top of the three-dimensional multi-layer aquaculture platform and the waste heat outlet, and the waste heat outlet is connected to the outlet.

[0020] The beneficial effects of this invention are:

[0021] In this invention, the air outlet duct is located at the top of the three-dimensional multi-layer breeding platform, and the position of the air outlet duct is higher than the three-dimensional multi-layer breeding platform. With the above structure, a height difference is formed between the air outlet duct and the air inlet duct. During the insect breeding process, heat is generated, resulting in a higher air temperature at the air inlet duct and a lower temperature at the air outlet duct. In this way, the hot air at the air inlet duct rises and the cold air at the air outlet duct falls, forming a natural air circulation inside and outside the three-dimensional multi-layer breeding platform, which can effectively improve ventilation efficiency and reduce energy consumption.

[0022] Meanwhile, existing traditional ventilation systems in multi-level aquaculture platforms use ducts to ventilate from one end of the platform to the other. The length-to-width ratio of these platforms is typically 4-10, resulting in long airflow distances and significant pressure losses. This invention utilizes transverse ventilation ducts between the aquaculture platforms, significantly shortening the airflow distance compared to the traditional longitudinal duct system. This effectively reduces pressure loss and improves ventilation efficiency. Attached Figure Description

Detailed Implementation

[0039] 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Example 1

[0041] like Figure 1 and 2 As shown, an energy-saving ventilation device for a three-dimensional multi-layer aquaculture platform is provided, wherein the natural ventilation device includes an air inlet mechanism 1 and / or an air outlet mechanism 2.

[0042] The air intake mechanism 1 includes a main air intake 1-3 that is installed on the side of the three-dimensional multi-layer aquaculture platform and sealed to the side. The air intake mechanism 1 can be configured with different structures according to actual needs. In this embodiment, the main air intake 1-3 is an integral structure that completely covers the side of the three-dimensional multi-layer aquaculture platform. This type of structure is suitable for the overall feeding and discharging aquaculture mode of a single aquaculture platform and can perform ventilation operation on each transverse ventilation duct 8 without discrimination.

[0043] Several air inlet pipes 1-2 are installed on the main air inlet section 1-3 at different locations. The specific positions of the air inlet pipes 1-2 can be set as needed, such as at the top or bottom of the main air inlet section 1-3, to facilitate rapid and uniform air intake. In this embodiment, they are set at the bottom of the main air inlet section 1-3. An air inlet valve is installed on the air inlet pipe 1-2 to control the air volume. Heat exchange mechanisms, filtration mechanisms, sterilization mechanisms, and other equipment can be installed at the inlet of the air inlet pipe 1-2 as needed to perform operations such as filtering, sterilizing, heating, cooling, dehumidifying, and humidifying the air, thereby more effectively regulating the insect breeding and drying environment and improving breeding efficiency.

[0044] In this invention, the air inlet 1-1 consists of several elliptical holes, the length of which is slightly less than the length of the transverse ventilation duct 8. This ensures a large air volume. The air inlet valve is a similar butterfly valve, including a rectangular valve plate 1-5. The rectangular valve plate 1-5 is fixed on the air valve shaft 1-4, and the air valve shaft 1-4 is installed together with the motor.

[0045] For areas where air temperature and humidity do not change much and are suitable for insect farming in the long term, it is not necessary to install an air intake mechanism.

[0046] The air outlet mechanism 2 is located on the other side of the three-dimensional multi-layer aquaculture platform and is sealed to the main air outlet 2-5 on the side. The air outlet mechanism 2 can be configured with different structures according to actual needs. In this embodiment, the main air outlet 2-5 is an integral structure that completely covers the other side of the three-dimensional multi-layer aquaculture platform. This type of structure is suitable for the overall feeding and discharging aquaculture mode of a single aquaculture platform and can perform ventilation operation on each transverse ventilation duct 8 without discrimination.

[0047] The air outlet mechanism 2 and the air inlet mechanism 1 are set on both sides of the longitudinal direction of the breeding platform, so that the air flows laterally on the breeding platform, which can greatly reduce the length of air flow, effectively reduce wind resistance, and improve ventilation efficiency.

[0048] An air outlet pipe 2-3 is installed on the main air outlet section 2-5, and an air outlet valve 2-2 is installed on the air outlet pipe 2-3 to adjust the air volume.

[0049] The air outlet duct 2-3 is located at the top of the three-dimensional multi-layer aquaculture platform, and the position of the air outlet duct 2-3 is higher than the three-dimensional multi-layer aquaculture platform; air circulates in the transverse ventilation duct 8 between two adjacent aquaculture platforms.

[0050] During insect farming, the insects' activity generates heat, causing the air temperature inside the farming platform to be higher than the temperature of the air outlets 2-3 times higher.

[0051] During the insect drying process, the introduction of hot air causes the air temperature inside the breeding platform to be higher than the temperature at the air outlets of ducts 2-3. Therefore, throughout the operation of the breeding platform, the air temperature inside the platform remains the same as the air temperature at the air outlets of ducts 2-3, creating a temperature difference between the air inlet ducts 1-2 and the air outlets. This causes the hot air to rise and be expelled through the air outlets 2-3, creating a negative pressure environment inside the breeding platform. This generates suction, automatically drawing air from the air inlet ducts 1-2 into the breeding platform, forming a self-circulating air system. This provides natural ventilation to the breeding platform, is low-cost, and pollution-free.

[0052] The higher the exhaust duct 2-3 is, the better the natural ventilation effect. To further improve the ventilation effect, a negative pressure fan 2-1 can be installed on the exhaust duct 2-3. The air discharged from the exhaust outlet can be collected and treated for air purification as needed, depending on the actual situation.

[0053] Depending on the actual breeding environment, insulation layers 5 can be installed on the air inlet mechanism 1 and the air outlet mechanism 2 to effectively ensure heat exchange, reduce energy consumption, and ensure that insects always have a good growth environment.

[0054] like Figure 3 As shown, in order to improve the heat exchange effect, especially in winter when the air temperature is low and heating is required, the technical solution adopted by the present invention is: energy-saving ventilation also includes a waste heat utilization mechanism, and the air inlet pipe 1-2 and the air outlet pipe 2-3 are connected to the waste heat utilization mechanism.

[0055] The structure of the waste heat utilization mechanism can be selected according to the actual situation, and suitable heat exchange equipment can be selected. The mechanism used in this embodiment is as follows: the waste heat utilization mechanism is a waste heat outlet 2-4 set on the top of the three-dimensional multi-layer aquaculture platform. The air inlet pipe 1-2 passes through the waste heat outlet 2-4. A heat insulation layer 5 is provided between the top of the three-dimensional multi-layer aquaculture platform and the waste heat outlet 2-4. The waste heat outlet 2-4 is connected to the outlet.

[0056] With the above-mentioned mechanism, the air inlet pipe 1-2 passes through the waste heat utilization section in the reverse direction. The heat from the air in the waste heat utilization section is used to heat the air inside the air inlet pipe 1-2, thereby raising its temperature and providing heating and ventilation for the interior of the aquaculture platform. Alternatively, the air inlet pipe 1-2 can be passed entirely through the air outlet section as needed to further improve the waste heat utilization efficiency.

[0057] The ventilation method of the present invention will be further explained in conjunction with a specific three-dimensional insect breeding facility.

[0058] like Figure 1 , 4 As shown in Figure 5, the three-dimensional insect breeding system includes a main frame 4, several layers of breeding structures 3 set on the main frame 4, a top plate 6, and a bottom plate 11.

[0059] The structure of the breeding facility 3 can be adopted from the existing three-dimensional insect breeding platform, such as a breeding box, or refer to patents CN115251011A, CN113317283A, CN117016495A and CN220728829U.

[0060] In this embodiment, the aquaculture mechanism 3, as described above, includes a mounting frame 3-9, a left insect-blocking plate 3-4, a right insect-blocking plate 3-6, a conveyor belt 3-5, an active roller 3-7, a driven roller 3-1, and a feeding / discharging mechanism. The conveyor belt 3-5 is mounted on the mounting frame 3-9 via the active roller 3-7 and the driven roller 3-1. The left insect-blocking plate 3-4 and the right insect-blocking plate 3-6 are mounted on the mounting frame 3-9, with their bottoms in contact with the conveyor belt 3-5. The feeding / discharging mechanism is located at both ends of the conveyor belt 3-5. The feeding / discharging mechanism includes a baffle 3-2 and an electric push rod 3-8. The height of the baffle 3-2 is higher than the height of the left and right insect-blocking plates. This creates a transverse ventilation duct 8 in the space between the baffle 3-2 and the left and right insect-blocking mesh panels. The transverse ventilation duct 8 may be unstructured and can be configured as a breathable mesh, a sealing plate 12 with ventilation holes 7-8, etc., as needed. In this embodiment, no structure is provided. The driving roller and / or driven roller 3-1 are equipped with a power mechanism; in this embodiment, the driving roller is equipped with the power mechanism.

[0061] The conveyor belt 3-5 is made of breathable plastic mesh, metal mesh or cloth; in this embodiment, plastic mesh is used.

[0062] Since the conveyor belt 3-5 is long, it is prone to bending after material is laid. Therefore, a support mesh plate 3-3 can be installed in the middle of the conveyor belt 3-5, close to the top, to improve the support force of the conveyor belt 3-5. The support mesh plate 3-3 can be installed as a whole, or it can be installed under the conveyor belt 3-5 at the feeding end and / or the discharging end. In this embodiment, the support mesh plate 3-3 is installed at the feeding end, which can effectively prevent the material from squeezing and deforming the conveyor belt 3-5 at the feeding end during feeding.

[0063] The energy-saving three-dimensional insect breeding system also includes several water heating mechanisms 10, which are installed at the bottom of the breeding mechanism 3.

[0064] The water heating mechanism 10 is installed at intervals at the bottom of the breeding mechanism 3, or the water heating mechanism 10 is installed at the bottom of the lowest layer of the breeding mechanism 3.

[0065] This implementation adopts a water heating system 10 installed at the bottom of the breeding facility 3.

[0066] The water heating mechanism 10 is a conventional water heating mechanism 10, which includes water heating pipes, inlet and outlet, and is connected to the heating device.

[0067] like Figure 6 As shown, the three-dimensional multi-layer aquaculture platform also includes an energy-saving air conditioning device, including an air inlet regulating mechanism 7 and an air outlet regulating mechanism 9, which are respectively arranged on both sides of the three-dimensional multi-layer aquaculture platform.

[0068] The air intake adjustment mechanism 7 includes an upper air intake shaft 7-2, a lower air intake shaft 7-7, and an air intake shield. The upper air intake shaft 7-2 and the lower air intake shaft 7-7 are fixed to the upper and lower parts of the three-dimensional multi-layer aquaculture platform, respectively. The air intake shield is also provided with a fully sealed air intake area 7-3, a fully open air intake area 7-5, and a partially open air intake area 7-6. The partially open air intake area 7-6 is provided with several horizontal air inlets 7-4. The horizontal air inlets 7-4 are connected to the horizontal ventilation duct 8 between two adjacent aquaculture platforms. The length of the fully sealed air intake area 7-3, the fully open air intake area 7-5, and the partially open air intake area 7-6 is not less than the height of the aquaculture platform. In this embodiment, one horizontal air inlet 7-4 is provided, but multiple horizontal air inlets 7-4 can also be provided as needed or at intervals.

[0069] The air outlet adjustment mechanism 9 includes an upper air outlet shaft 9-1, a lower air outlet shaft 9-6, and an air outlet shielding cloth. The upper air outlet shaft 9-1 and the lower air outlet shaft 9-6 are respectively fixed to the upper and lower parts of the three-dimensional multi-layer aquaculture platform. The two ends of the air outlet shielding cloth are respectively fixed to the upper air outlet shaft 9-1 and the lower air outlet shaft 9-6. The air outlet shielding cloth is provided with a fully sealed air outlet area 9-3, a partially open air outlet area 9-4, and a fully open air outlet area 9-2. The partially open air outlet area is provided with a number of horizontal air outlets 9-5. The horizontal air outlets 9-5 are connected to the horizontal ventilation duct 8 between two adjacent aquaculture platforms. The lengths of the three areas, namely the fully sealed air outlet area 9-3, the partially open air outlet area, and the fully open air outlet area 9-2, are not less than the height of the aquaculture platform.

[0070] The air inlet and outlet windproof fabrics can be made of durable, non-breathable materials, such as a structure with a layer of plastic on the fabric.

[0071] The upper air inlet shaft 7-2, upper air outlet shaft 9-1, and lower air outlet shaft 9-6 are respectively connected to the first power mechanism 7-1. The first power mechanism 7-1 can be a motor, a chain drive mechanism, etc., and in this embodiment, a motor is used.

[0072] The ventilation method of this invention:

[0073] A. Heating of underfloor heating pipes: (e.g., ...) Figure 7 As shown, the air intake and exhaust regulating mechanisms are adjusted to ensure that the transverse ventilation ducts of each breeding unit are sealed, the entire breeding platform is sealed, the underfloor heating pipes are heated, and the hot air penetrates from bottom to top, so that the temperature and humidity of each breeding unit are consistent.

[0074] B. Ventilation / Cooling: (e.g.) Figure 8 As shown, adjust the air inlet and outlet regulating mechanisms to keep the transverse ventilation ducts of each breeding unit open. Adjust the opening degree and time of the air outlet and air inlet valves so that air is automatically drawn into the breeding platform under the action of the pressure difference between the inlet and outlet. The air flows in the transverse ventilation ducts of each breeding unit to keep the breeding platform with suitable temperature and humidity for breeding.

[0075] C. Full-layer penetration drying: such as Figure 9 As shown, the air intake channel of the main air intake section of the air intake mechanism is adjusted to the layer where the water heating mechanism is installed, and the air outlet mechanism is adjusted to the horizontal ventilation duct at the top of the breeding platform. After being heated by the water heating pipe, the hot air penetrates from bottom to top and enters the air outlet pipe from the horizontal ventilation duct at the top of the breeding platform to be discharged, thus drying the materials on the breeding mechanism.

[0076] Example 2

[0077] It is basically the same as Example 1, except that:

[0078] like Figure 10 and 11 As shown, the structures of the air inlet 1-3 and the air outlet can be configured in different forms according to the actual situation. For example, the main air inlet 1-3 includes several small air inlets 1-8, which completely cover the sides of the three-dimensional multi-layer aquaculture platform. Each small air inlet 1-8 can be equipped with an air inlet pipe 1-2 and an air inlet valve, which can more accurately control the air volume. Alternatively, one air inlet pipe 1-2 and an air inlet valve can be used.

[0079] The main air outlet includes several smaller air outlets 2-8, which completely cover the other side of the three-dimensional multi-layer aquaculture platform. Each smaller air outlet 2-8 can be equipped with an air outlet duct 2-3 and a negative pressure fan 2-1, allowing for more precise control of the airflow; alternatively, a single air outlet duct 2-3 and a negative pressure fan 2-1 can be used.

[0080] The small air inlets or small air outlets 2-8 are staggered on both sides of the three-dimensional multi-layer aquaculture platform. The small air inlets 1-8 and small air outlets 2-8 can be arranged horizontally or vertically; this embodiment uses a vertical arrangement.

[0081] In this embodiment, four small air inlets 1-8 and four small air outlets 2-8 are used. Two adjacent small air inlets 1-8 share one air inlet valve and are divided into natural air inlets and dry hot air inlets. Two adjacent small air outlets 2-8 share one air outlet valve 2-2 and are divided into natural air outlets and dry hot air outlets.

[0082] The air inlet and outlet using the above structure are as follows: Figure 12 As shown:

[0083] D. Mixed Ventilation and Drying: Adjust the air inlet and outlet regulating mechanisms. The transverse ventilation ducts of the corresponding breeding units in the natural wind inlet and outlet are open. The transverse ventilation ducts of the corresponding breeding units connected to the hot dry air inlet are open, while the side furthest from the inlet is closed. The transverse ventilation ducts of the corresponding breeding units connected to the hot dry air outlet are open, while the side furthest from the outlet is closed. Natural wind is automatically drawn into the natural wind inlet under the pressure difference between the inlet and outlet for transverse ventilation. Hot dry air is automatically drawn into the hot dry air inlet under the pressure difference between the inlet and outlet for drying operations on the breeding units that need to be dried.

[0084] The above structure allows for simultaneous ventilation and drying of the aquaculture platform, which helps improve the platform's efficiency and enables tiered aquaculture.

[0085] Example 3

[0086] like Figure 13 and 14 As shown, it is basically the same as in Embodiment 1, except that the main air intake can also be configured as follows as needed: the main air intake includes an air intake box 1-7, and the air intake box 1-7 is connected to the transverse ventilation duct 8 of each floor through the air intake duct 1-6.

[0087] The main air outlet includes an air outlet box 2-6, which is connected to the horizontal ventilation duct 8 of each floor through an air outlet duct 2-7.

[0088] The above structure allows for more precise air intake and exhaust, improving ventilation efficiency.

[0089] 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.
