Description

Technical Field

[0001] The present invention relates to the technical field of cold chain transportation, and in particular to a cold chain transportation insulation box and an insulation method. Background Art

[0002] Cold chain transportation is an important part of cold chain logistics. It requires that during the entire transportation process, the goods must be kept in a specific low-temperature environment to ensure their quality and safety. This mode of transportation is suitable for goods that require temperature control, such as fresh products, processed foods, pharmaceutical products, etc. The equipment in cold chain transportation mainly includes the following: refrigerated trucks, cold storage, cold chain boxes and refrigeration equipment.

[0003] A Chinese patent with authorization announcement number CN113650914B discloses a cold chain transport box and a cold chain transport method thereof, which includes a box body and a box cover, the box cover is hinged to the box body, a mezzanine is provided in the box body, a plurality of horizontally arranged support plates are provided in the mezzanine, and the plurality of support plates are slidably connected to the mezzanine in a vertical direction, a plurality of bellows are provided in the mezzanine, the bellows and the support plates are alternately arranged, and the bellows are fixedly connected to the support plates, and one end of the bellows close to the bottom of the box body is fixedly connected to the bottom of the box body; a monitoring system is provided in the mezzanine, and the monitoring system includes a pressure monitoring module, a judgment module and an alarm module; the monitoring system is used to monitor the pressure on the mezzanine in real time.

[0004] The above patent can monitor the pressure on the interlayer in real time during the process of packing goods. If the pressure value corresponding to the pressure on the interlayer is monitored to be greater than the preset pressure value, the alarm module will send out an alarm message to remind the operator to stop the loss in time and reduce the possibility of the interlayer being deformed due to greater squeezing.

[0005] However, in the above patent, condensation water will be generated inwardly and on the interlayer wall, causing the cold chain transport items to be soaked, which may cause damage to their outer packaging. At the same time, the humid internal environment will also cause rapid bacterial proliferation. Summary of the invention

[0006] The present invention provides a cold chain transport insulation box and an insulation method, aiming to solve the problem of condensed water being generated inside the insulation box in the related art.

[0007] The cold chain transport insulation box of the present invention comprises: a box body;

[0008] The side wall of the box body has an outer wall and an inner wall, and a cavity is formed between the outer wall and the inner wall;

[0009] A first partition is provided in the cavity, which divides the cavity into a low-temperature cavity and a temperature-insulating cavity. The low-temperature cavity is close to the outer wall. An ice bag is provided in the low-temperature cavity. A water collecting bag is also provided on the side wall of the ice bag. The top of the water collecting bag is connected to the top of the ice bag, and the bottom of the ice bag is connected to the box body through a first elastic member. The temperature-insulating cavity is connected to the internal space of the box body.

[0010] Beneficial effect: Ice bags filled with ice cubes are placed in the low-temperature cavity to ensure that the interior of the box is in a low-temperature environment. There is also a temperature-insulating cavity between the low-temperature cavity and the interior space of the box to prevent excessive temperature difference on both sides of the inner wall of the box, causing condensation water to form on the inner side of the inner wall of the box, thereby preventing damage to the goods in the interior space of the box.

[0011] Preferably, a second partition is provided on the top of the first partition, and the second partition forms an air suction cavity in the upper part of the cavity, and an air inlet is provided at the end of the air suction cavity, and the air inlet is connected with the interior of the box body; an air outlet is provided on the second partition, and the air outlet can be connected with the temperature insulation cavity; a slider is slidably fitted in the air suction cavity, and the slider is connected to the bottom of the ice bag by a pull rope, and the slider is connected to the air suction cavity by a third elastic member.

[0012] The effect is that after the ice cubes in the ice bag melt into water, the first elastic member stretches and pushes the bottom of the ice cubes to move upward, and then pulls the slider through the pull rope to form a negative pressure in the air intake cavity, which can suck the hot and humid air in the upper layer of the box into the air intake cavity, ensuring a dry and low-temperature environment inside the box space.

[0013] Preferably, a mesh plate is further provided at the bottom of the cavity, and a water-absorbing sponge is provided between the mesh plate and the bottom surface of the box.

[0014] The effect is that condensed water will condense on the outer wall of the ice bag, and the condensed water can fall along the water collection bag onto the mesh plate and then be absorbed by the absorbent sponge.

[0015] Preferably, the mesh plate is slidably matched with the box body, a baffle is provided at the bottom of the ice bag, the baffle can stop against the mesh plate, and a drain is provided at the bottom of the box body, the drain is located below the absorbent sponge and connected to the outside.

[0016] The effect is that when the bottom of the ice bag is at the lowest end, the blocking rod can press the water-absorbing sponge downward, thereby squeezing out the condensed water absorbed by the water-absorbing sponge, and the squeezed water can be discharged from the box through the drain port.

[0017] Preferably, the first partition is connected to the inner wall by a second elastic member, a second vent is provided at the bottom of the low-temperature chamber, the second vent is connected to the outside, a rotating plate is rotatably matched at the bottom of the first partition, a stopper 20 is provided on the inner wall, the stopper 20 can stop against the rotating plate and push the rotating plate to rotate, thereby connecting the low-temperature chamber with the temperature insulation chamber.

[0018] The effect is that when the ice cubes in the ice bag gradually melt, the excess water in the ice bag is squeezed into the water collecting bag by the first elastic member, the water collecting bag expands, and pushes the first partition close to the inner wall, thereby reducing the volume of the insulation cavity, thereby ensuring the cooling effect of the ice bag and further ensuring that the internal space of the box is in a low temperature environment.

[0019] Preferably, the ice bag and the water collecting bag are made of flexible materials, and the side walls of the water collecting bag are provided with vertically distributed folds, and the condensed water can slide downwards along the folds.

[0020] A method for heat preservation of the cold chain transport heat preservation box described above comprises the following steps:

[0021] The first step is loading, loading the goods into the inner space of the box, filling the ice bag with ice cubes, and closing the box after loading is completed;

[0022] The second step is heat preservation. The ice cubes in the ice bag continuously absorb heat. The cold air at the bottom of the low-temperature cavity can enter the insulation cavity through the mesh plate, and then enter the internal space of the box from the insulation cavity. After the ice cubes absorb heat and turn into water, the first elastic member compresses the ice bag, squeezes the excess water into the water collecting bag, and at the same time pulls the sliding block to move, so that the air intake cavity absorbs the air in the upper layer of the internal space of the box, and the air in the air intake cavity enters the low-temperature cavity through the air outlet.

[0023] The effect is that the ice bag is placed in the low-temperature cavity, and the ice bag is filled with ice cubes, so as to ensure that the interior of the box is in a low-temperature environment. There is also a temperature insulation cavity between the low-temperature cavity and the internal space of the box, so as to prevent the temperature difference on both sides of the inner wall of the box from being too large, so that condensation water is generated on the inner side of the inner wall of the box, thereby preventing damage to the goods in the internal space of the box.

[0024] Preferably, in the initial state, the mesh plate squeezes the water-absorbing sponge. During the process of the first elastic member compressing the ice bag, the bottom end of the ice bag gradually rises, driving the mesh plate to rise, the water-absorbing sponge stretches, and can absorb condensed water dripping from the low-temperature chamber.

[0025] By adopting the above technical solution, the beneficial effects of the present invention are:

[0026] According to the cold chain transport insulation box and insulation method of the present invention, ice bags are placed in the low-temperature cavity, and ice cubes are contained in the ice bags to ensure that the interior of the box is in a low-temperature environment. There is also a temperature insulation cavity between the low-temperature cavity and the internal space of the box to prevent the temperature difference on both sides of the inner wall of the box from being too large, so that condensation water is generated on the inner side of the inner wall of the box, thereby preventing damage to the goods in the internal space of the box.

One side of the water collecting bag 4 is stopped against the support frame 7, and the other side is stopped against the partition, and a second vent 8 is provided at the bottom of the low-temperature cavity, and the second vent 8 is connected to the outside. A first vent 9 is provided at the bottom of the inner wall 102, and the temperature-insulating cavity is connected to the interior of the box body 1 through the first vent 9. A rotating plate 19 is also provided at the bottom of the first partition 2, and the rotating plate 19 is rotatably matched with the first partition 2. A stopper 20 is also provided on the inner wall 102, and the stopper 20 can stop against the rotating plate 19 and push the rotating plate 19 to rotate.

[0040] like Figure 2 and Figure 6 As shown, a second partition 10 is also provided on the top of the first partition 2. The second partition 10 is horizontally distributed, and its bottom end is stopped at the first partition 2. The second partition 10 forms an air suction cavity at the upper part of the cavity, and an air inlet 14 is provided at one end of the air suction cavity. The air inlet 14 is connected to the inside of the box body 1, and an air outlet 15 is provided on the second partition 10. The air inlet 14 and the air outlet 15 are respectively located at the two ends of the air suction cavity. A slider 11 is also slidably fitted in the air suction cavity. The slider 11 is connected to the bottom end of the support frame 7 through a pull rope 12. The support frame 7 can drive the slider 11 to slide in the air suction cavity by moving up and down. The slider 11 is connected to the air suction cavity through a third elastic member 13, and the third elastic member 13 is a spring.

[0041] like Figure 7 As shown, a mesh plate 16 is also provided at the bottom of the cavity, a water-absorbing sponge 17 is provided between the mesh plate 16 and the bottom surface of the box body 1, the mesh plate 16 and the box body 1 are slidably matched, a baffle 18 is provided at the bottom end of the support frame 7, and the bottom end of the baffle 18 can stop against the mesh plate 16, and a drain outlet is also provided at the bottom of the box body 1, the drain outlet is located below the water-absorbing sponge 17, and is connected to the outside.

[0042] According to the cold chain transport insulation box of the embodiment of the present invention, the insulation method thereof comprises the following steps:

[0043] The first step is loading, loading the goods into the internal space of the box body 1, and filling the ice bag 3 with ice cubes, and then closing the box body 1. At this time, the bottom of the ice bag 3 is at the bottom, the blocking rod 18 stops at the mesh plate 16, and squeezes the mesh plate 16, and then squeezes the water-absorbing sponge 17, and the squeezed water is discharged from the box body 1 through the drain port.

[0044] The second step is heat preservation. The ice cubes in the ice bag 3 continuously absorb heat, which lowers the temperature of the low-temperature cavity. The moisture in the air at the bottom of the low-temperature cavity condenses to form dry cold air. The dry cold air enters the insulation layer through the gap between the first partition plate 2 and the mesh plate 16, and then enters the interior of the box 1 through the first vent 9, so that the insulation layer and the interior of the box 1 are in a low-temperature environment. When the ice cubes gradually absorb heat and melt into water, the first elastic member 5 stretches and squeezes the excess water in the ice bag 3 upward, and the water enters the water collecting bag 4, thereby opening the water collecting bag 4. The water collecting bag 4 squeezes the first partition 2, so that the second elastic member 6 is compressed, and the first partition 2 gradually approaches the inner wall 102. At the same time, the support frame 7 moves upward under the action of the first elastic member 5, thereby pulling the slider 11 to move. The movement of the slider 11 forms a negative pressure in the suction chamber. Since the hot and humid air in the internal space of the box body 1 is distributed in the upper layer, and the cold air is distributed in the lower layer, the hot and humid air in the upper area of ​​the internal space of the box body 1 is sucked into the suction chamber under the action of negative pressure, thereby maintaining a low temperature and dry environment inside the box body 1. When the slider 11 moves to the right end, the air in the air intake chamber can enter the low-temperature chamber from the air outlet 15, and the ice bag 3 can absorb the heat in this part of the air. At this time, the first partition plate 2 is separated from the mesh plate 16 and approaches the inner wall 102. At this time, the rotating plate 19 rotates under the squeezing of the stopper 20, thereby connecting the low-temperature chamber and the insulation chamber. The dry cold air in the low-temperature chamber can enter the interior of the box body 1 through the insulation chamber, further ensuring the low-temperature environment inside the box body 1 until all the ice cubes in the ice bag 3 melt into water.

[0045] The condensed water attached to the outside of the water collecting bag 4 will slide down along the folds of the side wall of the water collecting bag 4 and finally fall on the mesh plate 16 , then pass through the mesh plate 16 and be absorbed by the absorbent sponge 17 .
