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.

A temperature sensor is installed on the top of the cooling box. A cold air outlet is provided on the front of the cooling box. A refrigeration machine is connected to the cold air outlet through a pipeline. The cooling device for aquatic product processing improves cooling efficiency by installing an exhaust fan in the exhaust outlet to quickly exhaust the hot air generated by the shrimp products in the cooling box after the refrigeration machine is started.

When the turnover column is driven to rotate by the motor under the action of external force, the turnover column drives the rotating ring to rotate by ninety degrees, so that the two staggered pipes in the turnover column are connected with the gas feeding port and the gas extraction port respectively. At this time, the gas pump extracts the gas from the conveying pipe through the staggered pipe connected with the gas extraction port, so that the gas in the far gas groove end is extracted into the staggered pipe through the conveying pipe.

[0013] A constant-temperature cooling process for aquatic product processing includes: S1: Start the system, and the compressor starts to work to compress low-temperature and low-pressure gas refrigerant into high-temperature and high-pressure gas, which is delivered to the condenser to release heat to the outside and condense into high-temperature liquid refrigerant. The liquid refrigerant is then decompressed and vaporized in the evaporator to absorb a large amount of heat in the box interior environment to achieve refrigeration, and then changes back to low-temperature and low-pressure gaseous refrigerant to be sucked into the compressor again to complete the cycle. The temperature control module monitors in real time through the temperature sensor, and accurately manages the heat absorption of the evaporator and the heat release of the condenser by controlling the start-stop and power size of the compressor to achieve and maintain the set constant-temperature environment. S2: When the system is running, the brushless motor in the vortex end is started synchronously to drive the fan blades to rotate, and the gas from the near air groove end is delivered to the air supply groove through the air groove opening, and the high-speed airflow is pushed into the inner cavity of the air groove plate. The airflow then adheres to and surrounds the inner wall of the inner cavity, and is uniformly sprayed from the narrow overflow channel. The negative pressure area is formed inside the inner cavity by using the Coanda effect, continuously absorbing a large amount of surrounding gas, and finally sending out the stable airflow after amplification, together with the cold air generated by the air groove plate, to push forward. At the same time, the vortex end continuously sucks gas from the near air groove end and the far air groove end, which are connected in the circulating air channel between the air layer and the inner box layer, so as to force the gas in the air layer to enter the circulating air channel through the air groove, and be continuously sucked away. The sucked gas is delivered upward through the connected vortex end, and is sent back to the air layer inside through the air supply groove in the air groove plate, to realize the forced circulation of the cold air in the storage space and ensure the uniform temperature in the air layer.

[0014] The above technical scheme can bring the following beneficial effects: 1. The constant-temperature cooling device for aquatic product processing, through the vortex end continuously sucking the gas from the near air slot end, and the other end of the near air slot end being connected in the circulating air channel between the aeration layer and the inner box layer, the gas in the circulating air channel is continuously sucked away, so that the gas in the aeration layer is forced to enter the circulating air channel through the aeration slot under the action of pressure difference, thereby forming a closed circulation, so that the cold gas is efficiently circulated and forced to flow in a specific space, effectively avoiding the formation of local temperature unevenness or airflow dead angle, and significantly improving the overall temperature uniformity and heat exchange efficiency.

[0015] 2. The constant-temperature cooling device for aquatic product processing, when the turnover column rotates to make the two straight-through pipes respectively butt joint with the gas feeding port and the gas sucking port, the system establishes a complete conveying path from the gas storage tank to the air pump through the communicating pipe, the input pipe, the straight-through pipe, and then to the far air slot end through the other side straight-through pipe and the conveying pipe, realizes the active injection of inert gas into the aeration layer circulation, achieves the dual effects of improving cooling efficiency and isolating oxygen, at the same time, when the turnover column rotates by ninety degrees to make the two staggered pipes respectively communicate with the gas port, the system path switches to be sucked back from the conveying pipe through the staggered pipe, and then sent back to the input pipe and the gas storage tank through the air pump and the other side staggered pipe, forming a gas recycling loop, realizing the recycling of inert gas, reducing gas consumption and operation cost, in addition, when the turnover column rotates to make all the pipes and ports staggered, the gas storage tank is in a completely sealed state, realizing the safe storage of gas to prevent leakage or pollution, in 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 connecting pipeline, fundamentally avoiding the leakage risk and mechanical wear caused by movable connection, thereby comprehensively improving the sealing, reliability and service life of the system.

[0016] 3. The constant-temperature cooling device for aquatic product processing, through the bottom surface turning plate sliding groove pulling the hanger, the hanger slides vertically along the sealing groove plate and drives the cross bar, the cross bar lifts the lifting frame through the short column, and the lifting frame moves up along the vertical sliding groove of the air slot plate, thereby automatically lifting the storage box away from the lower storage box, providing sufficient and convenient vertical operation space for workers to take aquatic products in the storage box and the storage box, avoiding the inconvenience of bending in deep cavity, at the same time, the gas pressure rod in the groove releases pressure and extends in the process, providing effective auxiliary support force for the turning of the cover plate, making the opening operation more labor-saving and stable and preventing accidental closing, enhancing the operation safety, in addition, when the hanger moves up and drives the clamping block above the sealing groove plate, rotating the clamping block can make it clamp the sliding communication, reliably preventing the sealing groove plate and the linkage components from falling under the action of gravity, providing stable and safe locking protection for the taking operation.

[0028] Working principle: The refrigeration system compresses low-temperature, low-pressure gaseous refrigerant into high-temperature, high-pressure gas through the compressor 45 via pipelines. 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 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 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 slot plate 55, 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. The aquatic products are stored in the box 1 by fishing and transferred to the processing flow line by transportation. In order to prevent the fresh aquatic products from being too fast to spoil during storage and transfer, the built-in air pump is connected with the air feeding port 68 and the air exhaust port 69 on the connecting end 67 respectively, and the relative rotation of the connected rotating ring 62 with the fixed seat 61 is driven by the turnover column 612 to adjust the pipeline that the air exhaust port 69 and the air feeding port 68 butt joint is the staggered pipe 610 or the straight pipe 611. When the two straight pipes 611 in the turnover column 612 are respectively butt jointed with the air feeding port 68 and the air exhaust port 69, the gas in the gas storage tank 66 enters the input pipe 64 through the communication pipe 65, then enters the butt jointed straight pipe 611 through the input pipe 64, and is sucked into the air exhaust port 69 through the straight pipe 611. Then the air pump transfers the gas from the inside to the adjacent straight pipe 611 through the air feeding port 68, and then the gas is transported to the delivery pipe 63 through the air feeding port 68 connected with the straight pipe 611, enters the inside of the far gas groove end 54, so that the vortex end 52 at the far gas groove end 54 transports the gas entering the inside to the inside of the aeration layer 43 for circulation. By increasing the inert gas, the inert gas enters the aeration layer 43 and contacts the surface of the aquatic products, and at the same time absorbs the heat of the surface of the aquatic products, improves the cooling storage effect, and at the same time, the inert gas contact isolates the surface oxygen gas from contacting the aquatic products. When the turnover column 612 is rotated by ninety degrees under the action of external force driven by the motor, the two staggered pipes 610 in the turnover column 612 are connected with the air feeding port 68 and the air exhaust port 69 respectively. At this time, the air pump draws the gas from the delivery pipe 63 through the staggered pipe 610 connected with the air exhaust port 69, so that the gas in the far gas groove end 54 is drawn into the staggered pipe 610 through the delivery pipe 63. The staggered pipe 610 transports the gas to the air pump through the air exhaust port 69 and discharges the gas to the staggered pipe 610 connected with the air feeding port 68 from the air feeding port 68. The gas is transported back to the input pipe 64 through the staggered pipe 610, and the gas is recycled by entering the gas storage tank 66 through the input pipe 64 and the communication pipe 65. When the turnover column 612 is rotated so that the staggered pipe 610 and the straight pipe 611 are staggered with the air feeding port 68 and the air exhaust port 69, the gas storage tank 66 is in a sealed state at this time. In this process, the connecting end 67 is relatively stationary with the bottom surface of the inner box layer 41. When the cover plate 2 is manually flipped, both cover plates 2 need to be flipped at the same time. When the cover plate 2 is flipped upward by the side hinges, the sliding boom 72 is pulled by the flipper sliding groove 71 opened on the bottom surface of the cover plate 2. With the change of the flip angle of the cover plate 2, the boom 72 will slide vertically along the sealing groove plate 42 and drive the horizontal rod 76. The horizontal rod 76 then lifts the lifting frame 78 upward through the connected short column 77, and the lifting frame 78 slides vertically along the vertical sliding groove 79 opened on the air chute plate 55. In this process, the air pressure rod 74 in the groove 73 releases pressure to extend and push the cover plate 2 to flip, and provides auxiliary support force for the cover plate 2. With the upward movement of the boom 72, the clamping block 75 is moved from the bottom to the top of the sealing groove plate 42. At this time, the clamping block 75 is rotated to clamp the sealing groove plate 42 and the sliding communication of the boom 72, preventing the sealing groove plate 42 from falling under the action of gravity. Through the vertical sliding groove 79, the storage box 711 is lifted away from the lower storage box 712, making it convenient for workers to take the aquatic products stored in the storage box 712 and the storage box 711.

The liquid refrigerant is then vaporized in the evaporator 47 under reduced pressure, absorbs a large amount of heat in the inside environment of the box 1, realizes refrigeration, and then changes back to low-temperature and low-pressure gaseous refrigerant to be sucked into the compressor 45 again to complete the cycle. 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-stop and power size of the compressor 45, so as to realize and maintain the set constant temperature environment; S2: When the system is running, the brushless motor 57 in the vortex end 52 is started synchronously to drive the fan blade 58 to rotate, deliver the gas from the near air chute end 51 to the air supply chute 510 through the air chute opening 59, and push the high-speed airflow to the inner cavity 511 of the air chute plate 55. The airflow then adheres to and surrounds the inner wall of the inner cavity 511, is uniformly sprayed from the narrow overflow channel 512, forms a negative pressure area inside the inner cavity 511 by using the Coanda effect, continuously rolls and sucks a large amount of surrounding gas, and finally delivers the stable airflow after mixing and amplification from the overflow channel 512, together with the cold air generated by the air chute plate 55, to push forward. At the same time, the vortex end 52 continuously sucks gas from the near air chute end 51 and the far air chute end 54, which are connected in the circulating air channel between the air layer 43 and the inner box layer 41, so as to force the gas in the air layer 43 to enter the circulating air channel through the air supply chute, and be continuously sucked away. The sucked away gas is delivered upward through the connected vortex end 52, is delivered back to the inside of the air layer 43 through the air supply chute 510 in the air chute plate 55, realizes forced circulation of the cold air in the storage space, and guarantees the uniform temperature in the inside of the air layer 43. S3: The caught aquatic products are stored in the box 1. In order to delay corruption, the inert gas preservation program is started. The built-in air pump is connected with the gas sending port 68 and the gas extraction port 69 on the connecting end 67 respectively. The rotation of the turnover column 612 is controlled to make the two straight-through pipes 611 in the interior respectively butt joint with the gas sending 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 is then sucked into the gas extraction port 69 by the air pump. The air pump transfers the gas from the gas sending port 68 to the adjacent straight-through pipe 611, and then to the delivery pipe 63, and finally to the interior of the far gas groove end 54. The gas is delivered to the interior of the air circulation layer 43 by the vortex end 52 at the far gas groove end 54, so as to make the inert gas contact with the surface of the aquatic products, absorb the heat on the surface of the aquatic products, and isolate oxygen, thereby improving the cooling storage effect; S4: When the inert gas needs to be recycled, the rotation of the turnover column 612 is driven by the motor to rotate the rotating ring 62 by 90 degrees, so that the two staggered pipes 610 in the interior respectively communicate with the gas sending port 68 and the gas extraction port 69. At this time, the air pump extracts the gas in the delivery pipe 63 through the staggered pipe 610 connected with the gas extraction port 69, so that the gas in the far gas groove end 54 is extracted into the staggered pipe 610, and is then discharged from the gas sending port 68 to the staggered pipe 610 on the other side by the air pump. The gas is then delivered back to the input pipe 64, and then returns to the gas storage tank 66 through the communication pipe 65, so as to complete the recycling of the gas. When the turnover column 612 rotates to make all the pipes staggered with the gas ports, 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 the aquatic products are taken, the two cover plates 2 are manually flipped at the same time. The cover plates 2 are opened and flipped upward through the side hinges. The flap sliding groove 71 opened on the bottom surface of the cover plate 2 pulls the hanger 72. With the change of the flip angle of the cover plate 2, the hanger 72 slides along the sealing groove plate 42 vertically and drives the horizontal rod 76. The horizontal rod 76 lifts the lifting frame 78 upward through the connected short column 77. The lifting frame 78 slides vertically along the vertical sliding groove 79 opened on the air groove plate 55. In this process, the air pressure rod 74 in the groove 73 releases pressure and extends to provide auxiliary support for the flip of the cover plate 2; S6: When the hanger 72 moves upward to drive the clamping block 75 to move from the bottom of the sealing groove plate 42 to the upper side, the clamping block 75 is manually rotated to clamp the sliding communication between the sealing groove plate 42 and the hanger 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.

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).
