Description

Technical Field

[0001] The utility model relates to the technical field of heat preservation boxes, in particular to an environmentally friendly heat preservation box for transporting sea cucumbers. Background Art

[0002] With the booming development of the sea cucumber industry, its transportation process faces many challenges. Traditional methods of transporting sea cucumbers often use simple packaging, such as ordinary foam boxes or simple cartons. These packages have many disadvantages: First, the thermal insulation performance is poor, and it cannot effectively resist changes in the external environment temperature, resulting in drastic temperature fluctuations in the box. As a creature that is extremely sensitive to temperature, the suitable survival temperature of sea cucumbers is usually 5℃ - 10℃. Unstable temperature can easily trigger a stress response in sea cucumbers, causing quality deterioration such as vomiting intestines and peeling of the sea cucumbers, and even mass death, causing huge economic losses to farmers and businesses.

[0003] Second, there is a lack of effective shock-proof and buffering design. Bumps and vibrations during transportation are unavoidable, and simple packaging cannot provide adequate protection for sea cucumbers, causing them to collide and squeeze with each other, resulting in damage to their surface, which not only affects their appearance, but also reduces their nutritional value and market value.

[0004] Third, in terms of environmental protection, most ordinary foam boxes are disposable and difficult to degrade. After a large number of uses, they cause serious white pollution, which does not meet the strict requirements of today's society for environmental protection. In addition, traditional packaging also has defects in humidity control. The water vapor produced by the breathing of sea cucumbers cannot be properly disposed of, which can easily lead to excessive humidity in the box, breeding bacteria and mold, and further threatening the freshness of sea cucumbers.

[0005] Therefore, those skilled in the art provide an environmentally friendly insulated box for transporting sea cucumbers to solve the problems raised in the above background technology. Utility Model Content

[0006] The purpose of the utility model is to provide an environmentally friendly heat preservation box for transporting sea cucumbers, so as to solve the problems raised in the above-mentioned background technology.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] An environmentally friendly thermal insulation box for transporting sea cucumbers comprises a box body, an inner liner is fixedly installed inside the box body, the inner liner is a rectangular frame, an inner cavity is arranged between the inner liner and the box body, a cold storage plate is movably inserted inside the inner cavity, there are four cold storage plates in total, which are respectively located on four sides of the inner liner, a plurality of grid frames are movably placed inside the inner liner, legs are fixedly connected to the lower end surfaces of the plurality of grid frames near four corners, the plurality of grid frames are movably stacked inside the inner liner through the legs, and the legs of the grid frames located at the bottom among the plurality of grid frames are shorter.

[0009] As a further solution of the utility model: a groove is provided on the surface of the cold storage plate close to the inner tank, and the height of the groove is higher than the height of the inner tank.

[0010] As a further solution of the utility model: a box cover is arranged at the upper end of the box body, and the box cover has the same structure as the box body, and is mainly composed of an outer shell and a heat-insulating layer.

[0011] As a further solution of the utility model: the shell is made of double-layer corrugated paperboard, the outer layer is high-strength kraft paper, the inner layer is moisture-proof paper, and a wavy corrugated paper core is sandwiched between the high-strength kraft paper and the moisture-proof paper.

[0012] As a further solution of the utility model: the heat-insulating layer is closely attached to the inner wall of the outer shell, and a layer of aerogel felt is laid, and a layer of plastic plate is fixedly connected to the inner wall of the aerogel felt.

[0013] As a further solution of the utility model: an elastic silicone pad is fixedly connected to the inner wall of the plastic plate.

[0014] As a further solution of the utility model: the plastic plate and the inner container are both made of food-grade recyclable plastic.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] Precise temperature and humidity control: Four cold storage plates are located on the four sides of the inner tank, which can release cold evenly from multiple directions, ensuring that the temperature in the box quickly reaches and stably maintains in the 5℃ - 10℃ range suitable for sea cucumbers. The groove design of the cold storage plate close to the inner tank is not only convenient for the removal and replacement of the cold storage plate, but also plays an auxiliary role in optimizing the distribution of cold energy, so that the cold energy can relatively accurately cover the inner tank space, reduce temperature dead corners, and help create a stable low-temperature environment. The aerogel felt insulation layer between the inner tank and the box body, with its excellent thermal insulation performance, effectively blocks the transmission of external heat, greatly reducing the degree to which the temperature in the box is affected by the external environment;

[0017] Multi-layer protection ensures that sea cucumbers are protected from vibration damage. First, the double-layer corrugated cardboard of the outer shell uses the toughness of the outer layer of high-strength kraft paper and the flexibility of the inner layer of moisture-proof paper, combined with the wavy corrugated paper core in the middle, to provide basic mechanical strength for the box body and buffer collision and extrusion during transportation. The elastic silicone pad between the liner and the aerogel felt serves as the second buffer defense line, which can absorb and disperse vibration energy and further reduce the impact force transmitted to the sea cucumber. Most importantly, the sea cucumbers are placed in layers in the grid frame, which is stacked by the legs to independently buffer the vibration of each layer of sea cucumbers, avoid mutual squeezing and collision of sea cucumbers, and protect the integrity and meat firmness of the sea cucumbers to the greatest extent.

[0018] Convenient operation and maintenance: The groove design of the cold storage plate greatly facilitates the operation process. When the cold storage plate needs to be replaced or maintained before or after transportation, the operator can easily take the cold storage plate out of or put it in the inner cavity through the groove without the help of complex tools, which reduces labor intensity and improves work efficiency. The layered design of the grid frame also improves the convenience of loading and unloading and inspection. When loading and unloading sea cucumbers, operations can be carried out layer by layer, which is orderly and efficient. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example 1: Reference Figure 1-5This embodiment provides an environmentally friendly insulated box for transporting sea cucumbers, including a box body 1, an inner liner 3 is fixedly installed inside the box body 1, the inner liner 3 is a rectangular frame, an inner cavity 14 is provided between the inner liner 3 and the box body 1, a cold storage plate 4 is movably inserted inside the inner cavity 14, there are four cold storage plates 4, which are respectively located on the four sides of the inner liner 3, a plurality of grid frames 5 are movably placed inside the inner liner 3, the lower end surfaces of the plurality of grid frames 5 are fixedly connected with legs 6 near the four corners, the plurality of grid frames 5 are movably stacked inside the inner liner 3 through the legs 6, and the legs 6 of the grid frames 5 located at the bottom of the plurality of grid frames 5 are shorter;

[0027] It should be noted that the legs of the bottom grid frame are relatively short, and the space between it and the bottom of the box is small. As a water storage space, for example, sea cucumbers still breathe during transportation and produce a certain amount of metabolic water. The water storage space prevents the sea cucumbers on the grid frame from contacting the metabolic water, preventing the sea cucumbers from being soaked.

[0028] Example 2: Reference Figure 1-5 This embodiment is based on the previous embodiment, and is different from the previous embodiment in that a groove 7 is provided on the surface of the cold storage plate 4 close to the inner liner 3, and the height of the groove 7 is higher than the height of the inner liner 3. A box cover 2 is provided at the upper end of the box body 1. The box cover 2 has the same structure as the box body 1, and is mainly composed of an outer shell and an insulation layer. The outer shell adopts double-layer corrugated cardboard, the outer layer is high-strength kraft paper 8, and the inner layer is moisture-proof paper 9. A wavy corrugated paper core 10 is sandwiched between the high-strength kraft paper 8 and the moisture-proof paper 9. The insulation layer is close to the inner wall of the outer shell, and a layer of aerogel felt 11 is laid. A layer of plastic plate 12 is fixedly connected to the inner wall of the aerogel felt 11, and an elastic silicone pad 13 is fixedly connected to the inner wall of the plastic plate 12. The plastic plate 12 and the inner wall of the inner liner 3 are both made of food-grade recyclable plastic.

[0029] It should be noted that:

[0030] In order to prevent the grid frame 5 from shaking inside the inner liner 3 during actual transportation, an elastic rubber strip that matches the inner wall of the inner liner 3 is provided on the outer edge of each grid frame 5. When the grid frame 5 is placed in the inner liner 3, the elastic rubber strip will fit closely with the inner wall of the inner liner 3, which plays a buffering role on the one hand to reduce the collision between the grid frame 5 and the inner liner 3; on the other hand, the friction force of the elastic rubber strip is used to keep the grid frame 5 in a relatively stable position in the inner liner 3, so as to avoid the sea cucumbers being squeezed and damaged due to shaking. At the same time, the elastic rubber strip is made of food-grade materials to ensure that the sea cucumbers will not be contaminated.

[0031] The contact edges of the box cover 2 and the box body 1 are provided with matching sealing grooves and sealing protrusions. The sealing protrusions have the same structure as the box cover 2 and the box body 1. When the box cover 2 is covered on the box body 1, the sealing protrusions will be tightly embedded in the sealing grooves to form a good sealing structure, effectively preventing cold air leakage.

[0032] Working principle: 1. Preparation stage: Before transportation, four cold storage plates 4 are placed in a low-temperature environment (such as a cold storage) for full pre-cooling, so that the temperature drops to the lower limit of the temperature range suitable for sea cucumber survival, usually around 5°C. At this time, the phase change material inside the cold storage plate 4 is in a cold storage state, storing a large amount of cold. At the same time, the box body 1 is cleaned and disinfected to ensure internal hygiene, and the grid frames 5 are stacked into the inner tank 3 in sequence. The placement density of each layer is reasonably arranged according to the size and number of sea cucumbers. Generally, the sea cucumber loading capacity of each layer of the grid frame 5 does not exceed 80% of its carrying capacity to reserve a certain amount of shockproof space;

[0033] 2. Packing and sealing: Place the sea cucumbers evenly in layers on each grid frame 5, cover the box cover 2, ensure that the box cover 2 and the box body 1 are well sealed to prevent cold air leakage. At this time, the cold storage plate 4 begins to play a role. Due to its close contact with the inner liner 3, the cold energy quickly diffuses into the inner liner 3. At the same time, the aerogel felt 11 insulation layer between the inner liner 3 and the box body 1 blocks the external heat from entering, maintaining the low temperature stability in the box;

[0034] 3. Transportation process: As the transport vehicle moves forward, bumps and vibrations are inevitable. The double-layer corrugated cardboard of the outer shell first buffers most of the impact force. Its unique structure disperses and absorbs the vibration energy. When the remaining vibration energy is transmitted to the inner liner 3, the elastic silicone pad 13 further weakens the vibration intensity. The grid frame 5 structure ensures that each layer of sea cucumbers is relatively independent and buffers vibrations. Sea cucumbers continue to breathe during transportation, and the metabolic water produced flows down along the grid frame 5 and gathers in the water storage space between the bottom of the box 1 and the legs 6 of the lowest grid frame 5. Since this space is relatively closed and small, water vapor is not easy to evaporate quickly, thereby maintaining the humidity in the box stable;

[0035] 4. Arrival at the destination: After arriving at the destination, open the box cover 2, take out the sea cucumber, and then the operator puts his fingers into the groove 7. Since the height of the groove 7 is higher than the height of the inner tank 3, the fingers can hold the cold storage plate 4 more conveniently. Then, the operator evenly pulls the cold storage plate 4 upward to gradually separate the cold storage plate 4 from the inner cavity 14. After taking out the cold storage plate 4, put it back into the cold storage for pre-cooling in preparation for the next transportation.

[0036] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
