Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cooling machines, in particular to a constant-temperature cooling device for aquatic product processing and a process. BACKGROUND

[0002] In the processing and transportation of aquatic products, maintaining their freshness is a key technical challenge. Traditional refrigeration methods often have large temperature fluctuations, uneven airflow circulation in the box, resulting in local temperature differences, and cannot effectively isolate oxygen, which accelerates spoilage. Therefore, the device integrates an efficient refrigeration cycle system and an airflow multiplication technology based on the Coanda effect. Through precise temperature adjustment by the temperature control module, it ensures a constant temperature environment in the box. Meanwhile, a switchable inert gas injection and recovery system is designed to actively isolate oxygen and enhance cooling. In combination with the linkage opening structure, the storage unit is automatically lifted, effectively improving the preservation effect of aquatic products during storage and transportation and the operational convenience.

[0003] Patent No. CN219474037U discloses a aquatic product processing cooling device, belonging to the technical field of aquatic product processing equipment, including a cooling box, the inside of the cooling box is a cavity and one side is open, the right side of the cooling box is hinged with a box door through a hinge shaft, one side of the box door is installed with a handle, the top of the cooling box is installed with a temperature sensor, the front of the cooling box is provided with a cold air outlet, the cold air outlet is connected with a refrigerator through a pipeline. The aquatic product processing cooling device of the patent improves the cooling efficiency by installing an exhaust fan in the exhaust port, which can quickly exhaust the hot air generated by the shrimp products in the cooling box after the refrigerator is started. The top plate is inclined, so that the water droplets formed on the top plate after the hot air rises can flow to one side, and the remaining water droplets are collected through the drainage groove, thereby avoiding the water droplets from falling on the products. However, the patent still has the problem of temperature difference between the edge and the center of the cooling space, which affects the cooling effect of aquatic products. Therefore, a constant-temperature cooling device for aquatic product processing and a process are proposed to solve the above problems. SUMMARY

[0004] The technical problem to be solved by the present application is to provide a constant-temperature cooling device for aquatic product processing and a process to solve the above problems.

[0005] To solve the above technical problems, the technical solution adopted by the present application is as follows: a constant-temperature cooling device for aquatic product processing, comprising a box body, the bottom of the box body is provided with a cooling mechanism;

[0006] The cooling mechanism includes an inner chamber layer, a sealing plate is fixedly connected to the top surface of the chamber, a ventilation layer is provided on the inner side of the inner chamber layer, partition plates are fixedly connected to the inner walls of the left and right sides of the ventilation layer, a compressor is installed on the bottom surface of the inner chamber layer, evaporators are installed on the left and right sides and the middle of the inner chamber layer, a condenser is provided at the bottom of the inner chamber layer, and a temperature control module and a temperature sensor are provided inside the chamber.

[0007] A circulating air duct mechanism is provided above the cooling mechanism. The circulating air duct mechanism includes a near air slot end and a far air slot end. Both the far air slot end and the near air slot end are fixedly connected to the bottom surface of the inner wall of the box. Multiple vortex ends are fixedly connected to the top surface of both the near air slot end and the far air slot end. An air chamber is fixedly connected to the top of the multiple vortex ends. An air supply duct is fixedly connected to the top surface of the air chamber. An air supply plate is fixedly connected to the outer wall of the air supply duct.

[0008] According to the above technical solution, the bottom surface of the box is provided with heat dissipation grooves, the bottom of the cooling mechanism is provided with a medium receiving and discharging mechanism, the interior of the ventilation layer is provided with an unfolding mechanism, the interior of the ventilation layer is provided with multiple equally spaced channel partitions, and the side of the partition plate is provided with a fitting groove.

[0009] According to the above technical solution, the top surface of the air chamber is provided with an air slot, the inner wall of the air slot is provided with an inner cavity, the side of the inner cavity is provided with an overflow channel, a brushless motor is installed inside the vortex end, the output shaft of the brushless motor is fixedly connected to a fan blade, and multiple brackets are fixedly connected to one side of the air slot plate.

[0010] According to the above technical solution, the ventilation layer is fixedly connected to the sealing plate, and the condenser, evaporator, and compressor are connected by metal pipes. A circulating air passage is provided between the ventilation layer and the inner box layer. Ventilation slots are equidistantly opened on the inner walls of the left and right sides of the ventilation layer. The air slot openings are interconnected with the inner cavity. The overall shape of the bracket is U-shaped, and the bracket is compatible with the external structure of the channel partition. The compressor contains refrigerant. The refrigeration system compresses the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gas through the compressor and pipelines. Subsequently, the gas releases heat to the outside and condenses into a high-temperature liquid in the condenser. This liquid is depressurized and vaporized in the evaporator, absorbing a large amount of heat from the surrounding environment, thereby achieving refrigeration. Finally, it turns back into a low-temperature, low-pressure gas and is drawn back into the compressor. The target temperature is set by the temperature control module, which monitors and controls the start-up, shutdown, and power of the compressor in real time through a temperature sensor. This manages the heat absorption of the evaporator and the heat release of the condenser to achieve constant temperature. When the compressor starts working, the brushless motor in the vortex end also starts working, driving the fan blades to rotate. The process involves rotating fan blades to transport gas from the adjacent air slots below the vortex end through the air slot opening into the air delivery slot. This high-speed airflow is pushed into the inner cavity of the air duct plate, causing it to adhere to and circulate within the cavity, exiting evenly through a narrow overflow channel. Utilizing the Coanda effect, the airflow adheres closely to the curved surface of the inner cavity wall, creating a negative pressure zone within the cavity. This negative pressure continuously draws in a large amount of surrounding gas from the rear and center of the cavity, ultimately mixing the drawn-in gas with the initial jet airflow. This mixture is then transformed into a stable and amplified uniform flow, exiting through the overflow channel. The airflow then drives the air duct plate to generate… The cold air is pushed forward together, while the vortex end draws gas from the inside of the near-slot end. The other end of the near-slot end, away from the vortex end, is connected to the circulation air channel between the ventilation layer and the inner box layer. When the gas in the circulation air channel is drawn away, the gas in the ventilation layer enters the circulation air channel through this ventilation slot. The gas inside the circulation air channel is continuously drawn away by the near-slot end and the far-slot end, and then transported to the upper air duct plate through the vortex end connected to the near-slot end and the far-slot end. It is then sent back to the ventilation layer through the air delivery slot in the air duct plate, realizing the circulation of cold air and ensuring the uniform temperature inside the ventilation layer.

[0011] According to the above technical solution, the medium receiving and discharging mechanism includes a fixed base, which is fixedly connected to the bottom surface of the middle part of the inner box layer. A rotating ring is rotatably connected to the inner side of the fixed base. A conveying pipe and an input pipe are fixedly connected to the left and right sides of the fixed base, respectively. A connecting pipe is fixedly connected to the end of the input pipe away from the fixed base. A gas storage tank is fixedly connected to the end of the connecting pipe away from the input pipe. A flipping column is fixedly connected to the inner side of the rotating ring. Two interlaced pipes and two straight pipes are fixedly connected to the inside of the flipping column. A connecting end is rotatably connected to the end of the flipping column away from the fixed base. An air supply port and an air extraction port are fixedly connected to the side of the connecting end, respectively.

[0012] According to the above technical solution, the gas storage tank is fixedly connected to the housing. The two staggered pipes are on the same horizontal line inside the rotating column, and the two straight pipes are on the same horizontal line inside the rotating column. The angle between each straight pipe and each staggered pipe is a right angle. An internal air pump is connected to the gas supply port and the gas extraction port on the connecting end, respectively. The rotating column drives the connected rotating ring to rotate relative to the fixed base, adjusting whether the pipes connecting the gas extraction port and the gas supply port are staggered pipes or straight pipes. When the two straight pipes inside the rotating column are connected to the gas supply port and the gas extraction port, respectively, the gas in the gas storage tank enters the input pipe through the connecting pipe, then enters the connected straight pipe through the input pipe, and then enters the gas extraction port through the straight pipe where it is drawn in by the air pump. Subsequently, the air pump transfers the gas from the inside through the gas supply port to the adjacent straight pipe, and then the gas is transported from the gas supply port to the delivery pipe through the straight pipe into the far-end gas tank. The vortex end at the far-end gas tank then transports the gas into the interior to the ventilation layer. The system circulates by adding inert gas, which enters the ventilation layer and contacts the surface of the aquatic products. This absorbs heat from the surface, improving cooling and storage efficiency. Simultaneously, the inert gas isolates the surface oxygen from the aquatic products. When the rotating column is driven by a motor under external force, it rotates the rotating ring 90 degrees, connecting the two staggered pipes inside the column to the air supply port and air extraction port, respectively. At this time, the air pump draws air from the delivery pipe through the staggered pipe connected to the extraction port, allowing the gas from the far end of the air tank to be drawn into the staggered pipe. The gas is then transported through the extraction port to the air pump and discharged from the air supply port to the staggered pipe connected to the air supply port. The gas is then transported back to the input pipe through the staggered pipe, and through the input pipe and connecting pipe into the gas storage tank for recovery. When the rotating column rotates and the staggered pipe and straight pipe are both separated from the air supply port and extraction port, the gas storage tank is sealed. During this process, the connecting end remains relatively stationary with respect to the bottom surface of the inner tank.

[0013] According to the above technical solution, the unfolding mechanism includes a flip-plate slide groove, which is opened on the bottom surface of the cover plate. A hanging rod is slidably connected to the inner side of the flip-plate slide groove. A crossbar is fixedly connected to the bottom end of the hanging rod. A short column is fixedly connected to the side of the crossbar. A lifting frame is fixedly connected to the end of the short column away from the crossbar. A support frame is fixedly connected to the top surface of the lifting frame. Vertical sliding grooves are opened on both the front and rear sides of the air duct plate. Four grooves are opened on the surface of the sealing plate. A pneumatic rod is installed on the inner side of each sealing plate. A locking block is hinged to the side of each hanging rod. A storage box is provided on the inner side of the support frame. A storage compartment is provided below the storage box.

[0014] According to the above technical solution, the lifting rod is slidably connected to the sealing plate, the vertical sliding groove is slidably connected to the lifting frame, and the top of the pneumatic rod is fixedly connected to the bottom surface of the cover plate. When the cover plate is manually flipped, both cover plates need to be flipped simultaneously. When the cover plate is flipped upwards by the side hinge, the cover plate pulls the sliding lifting rod through the flip plate sliding groove opened on the bottom surface. As the flipping angle of the cover plate changes, the lifting rod will slide vertically along the sealing plate and drive the horizontal bar. The horizontal bar will lift the lifting frame upwards through the connected short column, so that the lifting frame slides vertically along the vertical sliding groove opened on the air channel plate. During this process, the pneumatic rod in the groove releases pressure and extends to push the cover plate to flip, and provides auxiliary support force for the cover plate. As the lifting rod moves upwards, it drives the locking block to move from the bottom of the sealing plate to the top. At this time, the locking block is rotated to lock the sealing plate and the lifting rod at the sliding connection point, preventing the sealing plate from falling under the action of gravity. The vertical sliding groove lifts the storage box away from the storage box below, making it convenient for workers to take out the storage box and the aquatic products stored in the storage box.

[0015] A constant-temperature cooling process for aquatic product processing includes:

[0016] S1: The system starts, the compressor starts working, compresses the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gas, and delivers it to the condenser to release heat to the outside and condense into a high-temperature liquid refrigerant. The liquid refrigerant then depressurizes and vaporizes in the evaporator, absorbing a large amount of heat from the internal environment of the chamber to achieve cooling. Afterwards, it turns back into a low-temperature, low-pressure gaseous refrigerant and is drawn back into the compressor to complete the cycle. The temperature control module monitors in real time through a temperature sensor and precisely manages the heat absorption of the evaporator and the heat release of the condenser by controlling the start / stop and power of the compressor to achieve and maintain the set constant temperature environment.

[0017] S2: When the system is running, the brushless motor in the vortex end starts synchronously, driving the fan blades to rotate. It delivers the gas from the near air slot end to the air supply slot through the air slot opening and pushes the high-speed airflow into the inner cavity of the air supply slot. The airflow then adheres to and surrounds the inner wall of the inner cavity and is evenly sprayed out from the narrow overflow channel. Using the Coanda effect, it drives the cold air generated by the air duct plate to push forward together. At the same time, the vortex end continuously draws gas from the near air slot end and the far air slot end. Both ends are connected to the circulation air channel between the ventilation layer and the inner box layer, thereby forcing the gas in the ventilation layer to enter the circulation air channel through the ventilation slot and be continuously drawn away. The drawn-away gas is transported upward through the connected vortex end and sent back to the ventilation layer through the air supply slot in the air duct plate, realizing the forced circulation of cold air in the storage space and ensuring the uniform temperature inside the ventilation layer.

[0018] S3: After the aquatic products are caught, they are placed in the box for storage. To delay spoilage, the inert gas preservation program is activated. The built-in air pump is connected to the air supply port and the air extraction port on the connection end respectively. The rotation of the tilting column is controlled so that the two straight pipes inside are connected to the air supply port and the air extraction port respectively. The inert gas in the gas tank then enters the input pipe through the connecting pipe, and is then sucked in from the air extraction port by the air pump through the connected straight pipe. The air pump transfers the gas from the air supply port to the adjacent straight pipe and delivers it to the delivery pipe, entering the interior of the far air tank. Finally, the gas is delivered from the vortex end at the far air tank end to the interior of the ventilation layer to participate in the circulation, so that the inert gas comes into contact with the surface of the aquatic products. While absorbing the surface heat, it isolates oxygen, thereby improving the cooling and storage effect.

[0019] S4: When inert gas needs to be recovered, the rotating column driven by the motor rotates the rotating ring by 90 degrees, so that the two interlaced pipes inside are connected to the gas supply port and the gas extraction port respectively. At this time, the gas pump draws gas from the delivery pipe through the interlaced pipe connected to the gas extraction port, so that the gas in the far gas tank end is drawn into the interlaced pipe, and then discharged from the gas supply port to the interlaced pipe on the other side by the gas pump. The gas is then transported back to the input pipe, and then returned to the gas storage tank through the connecting pipe, completing the gas recovery. When the rotating column rotates and all pipes are misaligned with the gas ports, the gas storage tank is in a sealed state. During this process, the connection end and the bottom surface of the inner box layer remain relatively stationary to ensure reliable connection.

[0020] S5: When taking water products, manually flip the cover plates on both sides at the same time. The cover plates open and flip upwards through the side hinges. The flip plate slide groove opened on the bottom surface pulls the lifting rod. As the flip angle of the cover plate changes, the lifting rod slides vertically along the sealing plate and drives the crossbar. The crossbar lifts the lifting frame upwards through the connected short column, so that the lifting frame slides vertically along the vertical slide groove opened in the air channel plate. During this process, the air pressure rod in the groove releases pressure and extends, providing auxiliary support for the flipping of the cover plate.

[0021] S6: When the boom moves upward and moves the locking block from the bottom to the top of the sealing plate, manually rotate the locking block to lock it at the sliding connection between the sealing plate and the boom, thereby reliably preventing the entire lifting mechanism from falling under gravity. Through this linkage lifting action, the storage box is raised and moved away from the storage box below, providing workers with ample and convenient operating space to take out the storage box and the aquatic products stored in the storage box.

[0022] The present invention, by adopting the above technical solution, can bring the following beneficial effects:

[0023] 1. This constant temperature cooling device for aquatic product processing continuously draws gas from the near-air slot end through the vortex end, while the other end of the near-air slot end is connected to the circulation air channel between the ventilation layer and the inner box layer. This allows the gas in the circulation air channel to be continuously drawn out, thereby forcing the gas in the ventilation layer to enter the circulation air channel through the ventilation slot under the action of pressure difference, thus forming a closed loop. This achieves efficient circulation and forced convection of cold air in a specific space, effectively avoiding the formation of local temperature unevenness or airflow dead zones, and significantly improving the overall temperature uniformity and heat exchange efficiency.

[0024] 2. This constant-temperature cooling device for aquatic product processing establishes a complete transport path from the gas storage tank through the connecting pipe, input pipe, and straight pipe to the air pump, and then through the other straight pipe and delivery pipe to the far end of the gas tank when the rotating column rotates to connect the two straight pipes to the air supply port and the air extraction port respectively. This achieves the dual effect of actively injecting inert gas into the ventilation layer for circulation, thereby improving cooling efficiency and isolating oxygen. Simultaneously, when the rotating column rotates 90 degrees to connect the two staggered pipes to the air ports respectively, the system path switches to a path where the gas is drawn back through the delivery pipe and staggered pipe, and then through the air pump and... On the other side, the staggered pipes return to the input pipe and the gas storage tank, forming a gas recovery loop to realize the recycling of inert gas, reduce gas consumption and operating costs. In addition, when the tilting column rotates to the point where all pipes and ports are staggered, the gas storage tank is in a completely sealed state, realizing the safe storage of gas and preventing leakage or contamination. During this process, the connection end and the bottom surface of the inner box layer remain relatively stationary, ensuring the stability and reliability of the external air pump connection pipeline, fundamentally avoiding the risk of leakage and mechanical wear caused by moving connections, thereby comprehensively improving the system's sealing performance, reliability and service life.

[0025] 3. This constant temperature cooling device for aquatic product processing uses a bottom flip-plate slide groove to pull the lifting rod, which slides vertically along the sealing plate and drives the crossbar. The crossbar lifts the lifting frame through a short column, causing the lifting frame to move upward along the vertical slide groove of the trough plate. This automatically lifts the storage box away from the storage box below, providing ample and convenient vertical operating space for workers to retrieve the storage box and aquatic products inside. This avoids the inconvenience of bending over in deep cavities. At the same time, the pneumatic rod in the groove releases pressure and extends during the process, providing effective auxiliary support for the cover plate to flip, making the opening action easier and smoother and preventing accidental closure, thus enhancing operational safety. In addition, when the lifting rod moves upward and drives the locking block above the sealing plate, rotating the locking block can lock it at the sliding connection, reliably preventing the sealing plate and linkage components from falling under gravity, providing a stable and safe locking guarantee for the retrieval operation.

[0041] 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.

[0042] Please see Figures 1-14 An embodiment of the present invention is: a constant temperature cooling device for aquatic product processing, comprising a box 1, wherein a cooling mechanism 4 is provided at the bottom of the box 1;

[0043] The cooling mechanism 4 includes an inner box layer 41, a sealing plate 42 fixedly connected to the top surface of the box body 1, a ventilation layer 43 provided on the inner side of the inner box layer 41, a partition plate 44 fixedly connected to the inner walls of the left and right sides of the ventilation layer 43, a compressor 45 installed on the bottom surface of the inner box layer 41, an evaporator 47 installed on the left and right sides and the middle of the inner box layer 41, a condenser 46 provided at the bottom of the inner box layer 41, and a temperature control module and a temperature sensor provided inside the box body 1.

[0044] A circulating air passage mechanism 5 is provided above the cooling mechanism 4. The circulating air passage mechanism 5 includes a near air slot end 51 and a far air slot end 54. Both the far air slot end 54 and the near air slot end 51 are fixedly connected to the bottom surface of the inner wall of the housing 1. Multiple vortex ends 52 are fixedly connected to the top surface of both the near air slot end 51 and the far air slot end 54. An air chamber 53 is fixedly connected to the top of the multiple vortex ends 52. An air supply duct 510 is fixedly connected to the top surface of the air chamber 53. An air supply duct plate 55 is fixedly connected to the outer wall of the air supply duct 510.

[0045] The bottom surface of the housing 1 is provided with heat dissipation grooves 3, the bottom of the cooling mechanism 4 is provided with a medium receiving and discharging mechanism 6, the interior of the ventilation layer 43 is provided with an unfolding mechanism 7, the interior of the ventilation layer 43 is provided with multiple equally spaced channel partitions 48, and the side of the partition plate 44 is provided with a fitting groove 49.

[0046] The top surface of the air chamber 53 is provided with an air slot 59, the inner wall of the air supply slot 510 is provided with an inner cavity 511, the side of the inner cavity 511 is provided with an overflow channel 512, the inside of the vortex end 52 is equipped with a brushless motor 57, the output shaft of the brushless motor 57 is fixedly connected with a fan blade 58, and a number of brackets 56 are fixedly connected to one side of the air slot plate 55.

[0047] The ventilation layer 43 is fixedly connected to the sealing plate 42. The condenser 46, evaporator 47, and compressor 45 are connected by metal pipes. A circulating air passage is provided between the ventilation layer 43 and the inner box layer 41. Ventilation slots are equidistantly opened on the inner walls of the left and right sides of the ventilation layer 43. The air slot opening 59 is interconnected with the inner cavity 511. The overall shape of the bracket 56 is U-shaped, and the bracket 56 is compatible with the external structure of the channel partition 48. The compressor 45 contains refrigerant. The refrigeration system compresses the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gas through the compressor 45 and pipelines. Then, it releases heat to the outside and condenses into a high-temperature liquid in the condenser 46. These liquids are depressurized and vaporized in the evaporator 47, absorbing a large amount of heat from the surrounding environment, thereby achieving refrigeration. The gas, now at a low temperature and low pressure, is drawn back into the compressor 45. A target temperature is set via a temperature control module, which uses a temperature sensor to monitor and control the compressor 45's start-up, shutdown, and power output in real time. This manages the heat absorption of the evaporator 47 and the heat release of the condenser 46 to maintain a constant temperature. When the compressor 45 is in operation, the brushless motor 57 within the vortex end 52 also operates. The brushless motor 57 drives the fan blades 58 to rotate, drawing gas from the adjacent gas slot end 51 below the vortex end 52 through the fan blades 58 and air through the air slot opening 59 into the air delivery slot 510. The high-speed airflow is then pushed into the inner cavity 511 of the air delivery slot 510, where it adheres to and circulates, passing through the inner wall of the inner cavity 511 and being evenly ejected from the narrow overflow channel 512. Utilizing the Coanda effect, the airflow closely follows the curved surface of the inner wall of the inner cavity 511, creating a negative pressure zone within the inner cavity 511. This negative pressure continuously draws in a large amount of surrounding gas from the rear and center of the inner cavity 511, ultimately mixing the drawn-in gas with the initial jet airflow. This mixture is then transformed into a stable and amplified uniform flow that exits from the overflow channel 512. The airflow carries the cold air generated by the air duct plate 55 forward. Meanwhile, the vortex end 52 draws gas from the inside of the near-air duct end 51. The other end of the near-air duct end 51, away from the vortex end 52, is connected to the circulation airway between the ventilation layer 43 and the inner box layer 41. When the gas in the circulation airway is drawn out, the gas in the ventilation layer 43 enters the circulation airway through this ventilation slot. The gas inside the circulation airway is continuously drawn in by the near-air duct end 51 and the far-air duct end 512. 4. The air is drawn away and then transported to the upper air duct plate 55 through the vortex end 52 connected to the near air duct end 51 and the far air duct end 54. It is then sent back into the ventilation layer 43 through the air delivery duct 510 within the air duct plate 55, achieving cold air circulation and ensuring uniform temperature inside the ventilation layer 43. The vortex end 52 continuously draws gas from the near air duct end 51, while the other end of the near air duct end 51 is connected to the circulation air passage between the ventilation layer 43 and the inner box layer 41. This continuously draws gas out of the circulation air passage, forcing the gas in the ventilation layer 43 to replenish the circulation air passage through the ventilation duct under the pressure difference, thus forming a closed loop. This achieves efficient circulation and forced convection of cold air within a specific space, effectively avoiding localized temperature unevenness or the formation of dead air zones.This significantly improves overall temperature uniformity and heat exchange efficiency.

A rotating ring 62 is rotatably connected to the inner side of the base 61. A delivery pipe 63 and an input pipe 64 are fixedly connected to the left and right sides of the base 61, respectively.

The tilting column 612 drives the connected rotating ring 62 to rotate relative to the fixed base 61, thereby adjusting whether the pipe connected to the gas extraction port 69 and the gas supply port 68 is a staggered pipe 610 or a straight pipe 611. When the two straight pipes 611 inside the tilting column 612 are connected to the gas supply port 68 and the gas extraction port 69 respectively, the gas in the gas storage tank 66 enters the input pipe through the connecting pipe 65. Inside 64, the gas enters the connected straight pipe 611 through the input pipe 64, and then enters the exhaust port 69 through the straight pipe 611 where it is drawn in by the air pump. The air pump then transfers the gas from the inside through the supply port 68 to the adjacent straight pipe 611, and then from the supply port 68 to the supply pipe 611, which in turn delivers it to the delivery pipe 63, entering the interior of the far-end air tank 54. The vortex end 52 at the far-end air tank 54 then delivers the gas into the ventilation layer 43 for circulation. By adding inert gas, the inert gas enters the ventilation layer 43 and contacts the surface of the aquatic products, absorbing heat from the surface and improving the cooling and storage effect. Simultaneously, the inert gas isolates the surface oxygen from contacting the aquatic products. When the tilting column 612 is driven by an external force using a motor... When rotating, the tilting column 612 drives the rotating ring 62 to rotate 90 degrees, so that the two interlaced pipes 610 inside the tilting column 612 are connected to the air supply port 68 and the air extraction port 69 respectively. At this time, the air pump draws air from the delivery pipe 63 through the interlaced pipe 610 connected to the air extraction port 69, allowing the gas in the far end of the gas tank 54 to be drawn into the interlaced pipe 610 through the delivery pipe 63. The interlaced pipe 610 delivers the gas to the air pump through the air extraction port 69 and discharges it from the air supply port 68 to the interlaced pipe 610 connected to the air supply port 68. The gas is then transported back to the input pipe 64 through the interlaced pipe 610, and enters the gas storage tank 66 through the input pipe 64 and the connecting pipe 65 for gas recovery. When the tilting column 612 rotates so that both the interlaced pipe 610 and the straight pipe 611 are connected to the air supply port 68... When the air intake port 69 is offset from the exhaust port 69, the air tank 66 is in a sealed state. During this process, the connecting end 67 is relatively stationary with the bottom surface of the inner chamber 41. When the tilting column 612 rotates to connect the two straight pipes 611 to the air supply port 68 and the exhaust port 69 respectively, the system establishes a complete transport path from the air tank 66 through the connecting pipe 65, the input pipe 64, the straight pipe 611 to the air pump, and then through the other straight pipe 611 and the delivery pipe 63 to the far end of the air tank 54. This achieves the active injection of inert gas into the ventilation layer 43 for circulation, thereby improving cooling efficiency and isolating oxygen. At the same time, when the tilting column 612 rotates 90 degrees to connect the two staggered pipes 610 to the air ports respectively, the system path switches to being drawn back from the delivery pipe 63 through the staggered pipes 610.The gas is then returned to the input pipe 64 and the storage tank 66 via an air pump and a staggered pipe 610 on the other side, forming a gas recovery loop. This achieves the recycling of inert gas, reducing gas consumption and operating costs. Furthermore, when the tilting column 612 rotates until all pipes and ports are misaligned, the storage tank 66 is in a completely sealed state, ensuring safe gas storage and preventing leakage or contamination. During this process, the connection end 67 remains relatively stationary with the bottom surface of the inner casing layer 41, ensuring the stability and reliability of the external air pump connection pipeline. This fundamentally avoids the risk of leakage and mechanical wear caused by moving connections, thereby comprehensively improving the system's sealing performance, reliability, and service life.

[0050] The unfolding mechanism 7 includes a flap slide 71, which is opened on the bottom surface of the cover plate 2. A hanging rod 72 is slidably connected to the inner side of the flap slide 71. A crossbar 76 is fixedly connected to the bottom end of the hanging rod 72. A short column 77 is fixedly connected to the side of the crossbar 76. A lifting frame 78 is fixedly connected to the end of the short column 77 away from the crossbar 76. A support frame 710 is fixedly connected to the top surface of the lifting frame 78. Vertical slide grooves 79 are opened on both the front and rear sides of the air duct plate 55. Four grooves 73 are opened on the surface of the sealing plate 42. A pneumatic rod 74 is installed on the inner side of each sealing plate 42. A locking block 75 is hinged to the side of each hanging rod 72. A storage box 711 is provided on the inner side of the support frame 710. A storage box 712 is provided below the storage box 711.

[0051] The boom 72 is slidably connected to the sealing plate 42, the vertical slide groove 79 is slidably connected to the lifting frame 78, and the top of the pneumatic rod 74 is fixedly connected to the bottom surface of the cover plate 2. When the cover plate 2 is manually flipped, both cover plates 2 must be flipped simultaneously. When the cover plate 2 is flipped upwards by the side hinge, the cover plate 2 pulls the sliding boom 72 through the flip plate slide groove 71 opened on the bottom surface. As the flipping angle of the cover plate 2 changes, the boom 72 will slide vertically along the sealing plate 42 and drive the horizontal bar 76. The horizontal bar 76 is then lifted upwards by the connected short column 77. The lifting frame 78 slides vertically along the vertical sliding groove 79 opened in the air duct plate 55. During this process, the air pressure rod 74 in the groove 73 releases pressure and extends to push the cover plate 2 to flip, and provides auxiliary support for the cover plate 2. As the lifting rod 72 moves upward, it drives the locking block 75 to move from the bottom of the sealing plate 42 to the top. At this time, the locking block 75 is rotated to lock the sealing plate 42 and the sliding connection between the lifting rod 72, preventing the sealing plate 42 from falling under the action of gravity. The storage box 711 is lifted away from the bottom by moving upward through the vertical sliding groove 79. The storage box 712 allows workers to easily retrieve the aquatic products stored in the storage box 712 and storage container 711. The bottom flip-plate slide 71 pulls the lifting rod 72, causing it to slide vertically along the sealing plate 42 and drive the horizontal bar 76. The horizontal bar 76, via the short column 77, raises the lifting frame 78, causing the lifting frame 78 to move upwards along the vertical slide 79 of the windward slide plate 55. This automatically lifts the storage container 711 away from the storage box 712 below, providing ample and convenient vertical space for workers to retrieve the aquatic products from the storage box 712 and storage container 711. The straight operating space avoids the inconvenience of bending over in deep cavities. At the same time, the pneumatic rod 74 in the groove 73 releases pressure and extends during the process, providing effective auxiliary support for the flipping of the cover plate 2, making the opening action more effortless and smooth and preventing accidental closure, thus enhancing operational safety. In addition, when the lifting rod 72 moves upward and drives the locking block 75 above the sealing plate 42, rotating the locking block 75 can lock it at the sliding connection, reliably preventing the sealing plate 42 and the linkage components from falling under the action of gravity, providing a stable and safe locking guarantee for the retrieval operation.

[0052] Working principle: The refrigeration system compresses low-temperature, low-pressure gaseous refrigerant into high-temperature, high-pressure gas through the compressor 45 via pipeline. This gas then releases heat and condenses into a high-temperature liquid in the condenser 46. This liquid then depressurizes and vaporizes in the evaporator 47, absorbing a large amount of heat from the surrounding environment, thus achieving refrigeration. Finally, it returns to low-temperature, low-pressure gas and is drawn back into the compressor 45. A temperature control module sets the target temperature, and the module uses a temperature sensor to monitor and control the compressor 45's start-up, shutdown, and power in real time. This manages the heat absorption of the evaporator 47 and the heat release of the condenser 46 to achieve constant temperature. When the compressor 45 starts working, the brushless motor 57 in the vortex end 52 also starts working. The brushless motor 57 drives the fan blades 58 to rotate, drawing gas from the adjacent air slot end 51 below the vortex end 52 through the fan blades 58 and into the air delivery slot 510 via the air slot opening 59. The high-speed airflow is pushed into the inner cavity 511 of the air delivery slot 510, where it adheres to and circulates, passing through the inner wall of the inner cavity 511 and exiting through the narrow overflow channel 5. 12 is uniformly ejected, utilizing the Coanda effect to flow closely along the curved surface of the inner wall of the inner cavity 511, creating a negative pressure zone inside the inner cavity 511. This negative pressure continuously draws in a large amount of surrounding gas from the rear and middle of the inner cavity 511, eventually mixing the drawn-in gas with the initial jet airflow, transforming it into a stable and amplified uniform flow that is delivered from the overflow channel 512. The airflow carries the cold air generated by the air duct plate 55 forward, while the vortex end 52 draws gas from inside the near-air duct end 51. The other side of the near-air duct end 51 is far from the vortex end 52. The end is connected to the circulating air passage between the ventilation layer 43 and the inner box layer 41. When the gas in the circulating air passage is drawn away, the gas in the ventilation layer 43 enters the circulating air passage through this ventilation slot. The gas inside the circulating air passage is continuously drawn away by the near air slot end 51 and the far air slot end 54, and then transported to the upper air duct plate 55 through the vortex end 52 connected to the near air slot end 51 and the far air slot end 54. It is then sent back to the interior of the ventilation layer 43 through the air delivery slot 510 in the air duct plate 55, realizing cold air circulation and ensuring uniform temperature inside the ventilation layer 43.

[0053] Aquatic products are harvested and stored in container 1, then transported to the processing line. During storage and transfer, to prevent rapid spoilage of fresh aquatic products, an internal air pump is connected to both the air supply port 68 and the air extraction port 69 on connection end 67. A rotating ring 62, driven by a tilting column 612, rotates relative to the fixed base 61, adjusting whether the pipes connecting the air extraction port 69 and the air supply port 68 are staggered pipes 610 or straight pipes 611. When the two straight pipes 611 inside the tilting column 612 are connected to the air supply port 68 and the air extraction port 69 respectively... At this time, the gas in the gas storage tank 66 enters the input pipe 64 through the connecting pipe 65, then enters the connected straight pipe 611 through the input pipe 64, and then enters the suction port 69 through the straight pipe 611 where it is drawn in by the air pump. Subsequently, the air pump transfers the gas from the inside through the air supply port 68 to the adjacent straight pipe 611, and then through the straight pipe 611 connected to the air supply port 68 to the delivery pipe 63, entering the interior of the far gas slot end 54. The vortex end 52 at the far gas slot end 54 transports the gas that has entered the interior to the ventilation layer 43 for circulation. By adding inert gas, the inert gas... The gas enters the ventilation layer 43 and comes into contact with the surface of the aquatic products. It absorbs heat from the surface of the aquatic products, improving the cooling and storage effect. Simultaneously, it isolates the surface oxygen from the aquatic products through inert gas contact. When the rotating column 612 is driven to rotate by a motor under external force, the rotating column 612 drives the rotating ring 62 to rotate 90 degrees. This connects the two interlaced pipes 610 inside the rotating column 612 to the air supply port 68 and the air extraction port 69, respectively. At this time, the air pump draws air from the delivery pipe 63 through the interlaced pipe 610 connected to the air extraction port 69, allowing the gas in the far-end air tank 54 to pass through the delivery pipe 63. The gas is drawn into the interlaced pipe 610, which is then transported to the air pump through the extraction port 69 and discharged from the supply port 68 to the interlaced pipe 610 connected to the supply port 68. The gas is then transported back to the input pipe 64 through the interlaced pipe 610, and then enters the gas storage tank 66 through the input pipe 64 and the connecting pipe 65 for gas recovery. When the tilting column 612 rotates and the interlaced pipe 610 and the straight pipe 611 are both misaligned with the supply port 68 and the extraction port 69, the gas storage tank 66 is in a sealed state. During this process, the connecting end 67 is relatively stationary with respect to the bottom surface of the inner box layer 41.

[0054] When manually flipping the cover plate 2, both cover plates 2 must be flipped simultaneously. As the cover plate 2 flips upward via the side hinges, the cover plate 2 pulls the sliding rod 72 through the flip plate groove 71 on the bottom surface. As the flipping angle of the cover plate 2 changes, the hanging rod 72 slides vertically along the sealing plate 42 and drives the crossbar 76. The crossbar 76 then lifts the lifting frame 78 upward via the connected short column 77, causing the lifting frame 78 to slide vertically along the vertical sliding groove 79 on the air duct plate 55. During this process, the air pressure in the groove 73... The rod 74 releases pressure and extends to push the cover plate 2 to flip, and provides auxiliary support for the cover plate 2. As the lifting rod 72 moves upward, it drives the locking block 75 to move from the bottom of the sealing plate 42 to the top. At this time, the locking block 75 is rotated to lock the sealing plate 42 and the lifting rod 72 at the sliding connection point, preventing the sealing plate 42 from falling under the action of gravity. The vertical sliding groove 79 moves upward to lift the storage box 711 away from the storage box 712 below, making it easier for workers to take out the aquatic products stored in the storage box 712 and the storage box 711.

[0055] A constant-temperature cooling process for aquatic product processing includes:

[0056] S1: Start the system. Compressor 45 starts working, compressing the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gas, which is then delivered to condenser 46 to release heat to the outside and condense into a high-temperature liquid refrigerant. The liquid refrigerant is then depressurized and vaporized in evaporator 47, absorbing a large amount of heat from the internal environment of the housing 1 to achieve cooling. Afterward, it turns back into a low-temperature, low-pressure gaseous refrigerant and is drawn back into compressor 45 to complete the cycle. The temperature control module monitors the temperature in real time through a temperature sensor and precisely manages the heat absorption of evaporator 47 and the heat release of condenser 46 by controlling the start / stop and power of compressor 45 to achieve and maintain the set constant temperature environment.

[0057] S2: When the system is running, the brushless motor 57 in the vortex end 52 starts synchronously, driving the fan blade 58 to rotate. The gas from the near air slot end 51 is delivered to the air supply slot 510 through the air slot port 59, and the high-speed airflow is pushed to the inner cavity 511 of the air supply slot 510. The airflow then adheres to and surrounds the inner wall of the inner cavity 511, and is evenly sprayed out from the narrow overflow channel 512. The Coanda effect is used to drive the cold air generated by the air duct plate 55 to push forward together. At the same time, the vortex end 52 continuously draws gas from the near air slot end 51 and the far air slot end 54. Both ends are connected to the circulation air channel between the ventilation layer 43 and the inner box layer 41, thereby forcing the gas in the ventilation layer 43 to enter the circulation air channel through the ventilation slot and be continuously drawn away. The drawn-away gas is transported upward through the connected vortex end 52 and sent back to the ventilation layer 43 through the air supply slot 510 in the air duct plate 55, realizing the forced circulation of cold air in the storage space and ensuring the uniform temperature inside the ventilation layer 43.

[0058] S3: After the aquatic products are caught, they are placed in the container 1 for storage. To delay spoilage, the inert gas preservation program is activated. The built-in air pump is connected to the air supply port 68 and the air extraction port 69 on the connection end 67 respectively. The rotating column 612 is controlled to rotate, so that the two straight pipes 611 inside are connected to the air supply port 68 and the air extraction port 69 respectively. The inert gas in the gas storage tank 66 then enters the input pipe 64 through the connecting pipe 65, and is then sucked in by the air pump from the air extraction port 69 through the connected straight pipe 611. The air pump transfers the gas from the air supply port 68 to the adjacent straight pipe 611 and delivers it to the delivery pipe 63, which enters the interior of the far air tank end 54. Finally, the gas is delivered from the vortex end 52 at the far air tank end 54 to the interior of the ventilation layer 43 to participate in circulation, so that the inert gas comes into contact with the surface of the aquatic products. While absorbing the heat on the surface, it isolates oxygen, thereby improving the cooling and storage effect.

[0059] S4: When inert gas needs to be recovered, the rotating column 612 driven by the motor drives the rotating ring 62 to rotate 90 degrees, so that the two interlaced pipes 610 inside are connected to the gas supply port 68 and the gas extraction port 69 respectively. At this time, the air pump draws air from the delivery pipe 63 through the interlaced pipe 610 connected to the gas extraction port 69, so that the gas in the far gas tank end 54 is drawn into the interlaced pipe 610, and discharged from the gas supply port 68 to the interlaced pipe 610 on the other side by the air pump. The gas is then transported back to the input pipe 64, and then returned to the gas storage tank 66 through the connecting pipe 65, thus completing the gas recovery. When the rotating column 612 rotates and all pipes are misaligned with the gas ports, the gas storage tank 66 is in a sealed state. During this process, the connection end 67 and the bottom surface of the inner box layer 41 remain relatively stationary to ensure reliable connection.

[0060] S5: When taking water products, manually flip the cover plates 2 on both sides at the same time. The cover plates 2 open and flip upward through the side hinges. The flip plate slide groove 71 opened on the bottom surface pulls the lifting rod 72. As the flip angle of the cover plates 2 changes, the lifting rod 72 slides vertically along the sealing plate 42 and drives the cross bar 76. The cross bar 76 lifts the lifting frame 78 upward through the connected short column 77, so that the lifting frame 78 slides vertically along the vertical slide groove 79 opened on the air duct plate 55. During this process, the air pressure rod 74 in the groove 73 releases pressure and extends, providing auxiliary support for the flipping of the cover plates 2.

[0061] S6: When the boom 72 moves upward and drives the locking block 75 from the bottom of the sealing plate 42 to the top, manually rotate the locking block 75 to lock the sliding connection between the sealing plate 42 and the boom 72, thereby reliably preventing the entire lifting mechanism from falling under gravity. Through this linkage lifting action, the storage box 711 is raised and moved away from the storage box 712 below, providing workers with ample and convenient operating space to take out the aquatic products stored in the storage box 712 and the storage box 711.

8. A water product processing constant temperature cooling device according to claim 7, characterized in that: Comprise: S1: start the system, the compressor (45) starts to work, the low-temperature and low-pressure gas refrigerant is compressed into high-temperature and high-pressure gas, is delivered to the condenser (46) to heat to the outside world and condenses into high-temperature liquid refrigerant, the liquid refrigerant is then decompressed in the evaporator (47) and vaporized, absorbs a large amount of heat in the environment inside the box (1), realizes refrigeration, and then changes back to low-temperature and low-pressure gaseous refrigerant and is sucked into the compressor (45) again, completes the cycle, and the temperature control module monitors in real time through the temperature sensor, and accurately manages the heat absorption of the evaporator (47) and the heat release of the condenser (46) by controlling the start and stop and power size of the compressor (45), to realize and maintain the set constant temperature environment; S2: when the system is running, the brushless motor (57) in the vortex end (52) starts synchronously, drives the fan blade (58) to rotate, delivers the gas from the near air slot end (51) to the air supply slot (510) through the air slot (59), and pushes the high-speed airflow to the inner cavity (511) of the air supply slot (510), the airflow then adheres to and surrounds the inner wall of the inner cavity (511), and is uniformly sprayed from the narrow overflow channel (512), the cold air generated by the air slot plate (55) is pushed forward together with the cold air, at the same time, the vortex end (52) continuously sucks the gas from the near air slot end (51) and the far air slot end (54), both ends are connected in the circulating air channel between the air layer (43) and the inner box layer (41), so that the gas in the air layer (43) enters the circulating air channel through the air slot, and is continuously sucked away, the sucked gas is delivered upward through the connected vortex end (52), and is delivered back to the inside of the air layer (43) through the air supply slot (510) in the air slot plate (55), realizing forced circulation of the cold air in the storage space, and ensuring uniform temperature in the air layer (43); S3: after fishing, the aquatic products are put into the box (1) for storage, in order to delay corruption, the inert gas preservation program is started, the air pump is connected with the gas supply port (68) and the gas extraction port (69) on the connection end (67) respectively, the rotation column (612) is controlled to rotate, the two straight-through pipes (611) in the inside are respectively connected with the gas supply port (68) and the gas extraction port (69), the inert gas in the gas storage tank (66) enters the input pipe (64) through the communication pipe (65), and then is sucked into the gas extraction port (69) by the air pump through the connected straight-through pipe (611), the air pump transfers the gas from the gas supply port (68) to the adjacent straight-through pipe (611), and delivers it to the delivery pipe (63), and enters the inside of the far air slot end (54), finally, the gas is delivered to the inside of the air layer (43) by the vortex end (52) at the far air slot end (54) to participate in circulation, so that the inert gas contacts with the surface of the aquatic products, absorbs the heat on the surface, and isolates oxygen, thereby improving the cooling and storage effect; S4: When it is necessary to recover the inert gas, the motor drives the turnover column (612) to rotate the rotating ring (62) by ninety degrees, so that the two staggered pipes (610) in it are respectively communicated with the gas inlet port (68) and the gas outlet port (69). At this time, the air pump draws gas from the conveying pipe (63) through the staggered pipe (610) connected with the gas outlet port (69), so that the gas in the far gas groove end (54) is drawn into the staggered pipe (610), and then discharged from the gas inlet port (68) to the other staggered pipe (610) through the air pump. The gas is then transported back to the input pipe (64), and then returned to the gas storage tank (66) through the communication pipe (65), completing the recovery of the gas. When the turnover column (612) rotates to make all the pipes staggered with the gas port, the gas storage tank (66) is in a sealed state. In this process, the connecting end (67) and the bottom surface of the inner box layer (41) remain relatively stationary to ensure reliable connection; S5: When taking the aquatic products, the two cover plates (2) are manually turned over at the same time. The cover plates (2) are turned over and opened upward through the side hinges. The flip plate sliding groove (71) opened in the bottom surface pulls the suspender (72) along with it. With the change of the turning angle of the cover plate (2), the suspender (72) slides along the vertical direction of the sealing groove plate (42) and drives the horizontal rod (76). The horizontal rod (76) is lifted upward through the short column (77) connected to it, so that the lifting frame (78) slides vertically along the vertical sliding groove (79) opened in the air groove plate (55). In this process, the gas pressure rod (74) in the groove (73) releases pressure and extends, providing auxiliary support force for the turning of the cover plate (2); S6: When the suspender (72) moves upward to drive the clamping block (75) to move from the bottom to the top of the sealing groove plate (42), the clamping block (75) is manually rotated to clamp the sliding communication part of the sealing groove plate (42) and the suspender (72), so as to reliably prevent the entire lifting mechanism from falling under the action of gravity. Through this linkage lifting action, the storage box (711) is lifted and away from the storage box (712) below, providing sufficient and convenient operation space for workers to take the aquatic products stored in the storage box (712) and the storage box (711).
