[0007] Preferably, the box body has a sandwich structure, and a partition is provided inside the box body to divide the interior of the box body into a first space and a second space. The storage tank is located in the first space, and the circulating fan and the refrigeration evaporator are located in the second space. The volume of the first space is larger than the volume of the second space, and the first space is larger than the second space and is connected at both the top and bottom.

[0008] Preferably, the circulating fan guides the airflow in a direction from bottom to top in the second space.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this technical solution clearer, the following detailed description, in conjunction with specific embodiments, further illustrates this technical solution. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this technical solution.

[0024] To address the challenges of refrigeration and low-temperature storage in large, enclosed containers in existing technologies, such as... Figure 1 As shown, this embodiment proposes an air-cooled material handling box, which includes a box body 10 and a box cover 20. The box body 10 has a sandwich structure. The inner box of the box body 10 is made of 304 stainless steel plate, the outer box is made of galvanized steel plate, and the insulation layer is filled with 100mm thick polyurethane.

[0025] Lifting and positioning devices 11 are provided at the four corners of the housing 10. These devices facilitate easier docking and sealing with the open top of the housing 10 after the lid 20 is lifted. Pressure balancing windows 13 are provided on the main extension surfaces of the left and right sides of the housing 10. These windows balance the gas pressure inside and outside the housing 10 after the air inside has cooled. A feed inlet 12 is provided on one side of the housing 10, penetrating the housing 10. The feed inlet 12 allows materials to be fed into the storage tank 50 inside the housing 10. The feed inlet 12 can be sealed using a plug or valve.

[0026] In this embodiment, the housing 10 is generally a cubic structure with a rectangular horizontal cross-section. A circulating fan 30 and a refrigeration evaporator 40 are installed on the side wall at one end along the length of the housing 10. Figure 1 As shown, the motor and heat dissipation unit of the circulating fan 30 are located outside the housing 10, while the refrigerant delivery pipeline of the evaporator 40 is opened on the side wall of the housing 10 in this direction.

[0027] like Figure 2 As shown, a partition 14 is provided inside the housing 10. The function of the partition 14 is to divide the left side of the housing 10 into a second space, in which the air drive component of the circulating fan 30 and the refrigeration component of the refrigeration evaporator 40 are located. The left side of the housing 10 is divided into a first space by the partition 14, in which the electronic scale 80 is located at the bottom. The top of the electronic scale 80 is configured as a plate-shaped weighing structure. A bracket 70 is provided on the top of the weighing structure, and a storage tank 50 is located above the bracket 70. That is, the storage tank 50 is mounted on the electronic scale 80 through the bracket 70. After tare, the electronic scale 80 can accurately weigh the current mass of the material in the storage tank 50. The electronic scale 80 can obtain the mass of the material stored in the storage tank 50, the current mass of the material in the storage tank, and the mass of the material removed from the storage tank 50.

[0028] In addition, a mesh-like return air window 141 is provided below the partition 14. The function of the return air window 141 is to serve as a channel for air in the first space of the housing 10 to enter the second space. The return air window 141 is made of mesh material, which can prevent debris from entering the second space, and thus prevent debris from entering the refrigeration evaporator 40 and the circulating fan 30, affecting the normal operation of the refrigeration evaporator 40 and the circulating fan 30.

[0029] like Figure 3 As shown, a cold air inflow channel 21 and an air distribution mesh 22 are specially designed inside the box cover 20. The box cover 20 is generally trapezoidal in structure and serves as an insulated cover. The cold air inflow channel 21 is located inside the box cover 20, with one end being elongated. After the box body 10 and the box cover 20 are fastened together, this end of the cold air inflow channel 21 connects with the top of the second space. The first side of the cold air inflow channel 21 uses the space between the top wall of the box cover 20 and the air distribution mesh 22 as an air distribution channel. In this embodiment, the air distribution mesh 22 is a mesh with multiple elongated holes.

[0030] Combination Figure 2 and Figure 3 As shown, after the box body 10 and the box cover 20 are connected, the cold air inflow channel 21 connects with the top of the second space, and the contact points between the box body 10 and the box cover 20 are sealed by a sealing strip.

[0031] like Figure 5As shown, when the evaporator 40 and the circulating fan 30 are working normally, air first enters the second space from the first space through the return air window 141 below the partition 14. After being cooled by the evaporator 40, it is driven upward by the circulating fan 30 to the cold air inflow channel 21 of the cover 20. Then, after being evenly distributed between the air distribution plate 22 and the top wall of the cover 20, it returns to the first space through the mesh on the air distribution plate 22. Since the air distribution plate 22 and the storage tank 50 are roughly vertically opposite each other, the cold air is driven by the circulating fan 30 to flow downward toward the storage tank 50. On the other hand, due to its higher density, the cold air will flow downward on its own and pass through the storage tank 50. During this process, the storage tank 50 exchanges heat fully with the cold air and then returns to the second space through the return air window 141 on the partition 14, forming a circulation.

[0032] Combination Figure 2 and Figure 4 As shown, the housing 10 has air guide plates 60 positioned at the lower half of the storage tank 50 to guide the cold air toward the lower half of the storage tank 50. The storage tank 50 is cylindrical, and the air guide plate 60 includes air guide plate bodies 61 disposed on the left and right sides of the lower half of the storage tank 50. The air guide plate bodies 61 are curved plates that match the curvature of the outer surface of the storage tank 50, and the inner wall of the air guide plate bodies 61 facing the storage tank 50 is provided with air cutting strips to change the airflow direction. In this embodiment, the air cutting strips are strip-shaped plates extending along the length of the air guide plate bodies 61 and having a certain angle with the air guide plate bodies 61.

[0033] like Figure 6 As shown, cold air is evenly distributed and guided to flow rapidly on the outer annular wall of storage tank 50. Guided by the air guide plate 60 and altered by the air cutter, the cold air tends to flow towards storage tank 50, ensuring full contact with the curved surface of the lower half of storage tank 50. Finally, after heat exchange with storage tank 50, the cold air flows out of the area where the air guide plate 60 is located through the gaps between the air guide plates 60.

[0034] This air-cooled material handling box uses an air-guiding structure set in the box body 10 and the box cover 20, in conjunction with a circulating fan 30 and a refrigeration evaporator 40, to make the air inside the box body 10 refrigerated and flow to form a low-temperature circulating airflow. The air-guiding structure guides the low-temperature circulating airflow through the storage tank 50, forcing the low-temperature circulating airflow to exchange heat with the storage tank 50, so that the material inside the storage tank 50 is kept at a low temperature, realizing the combination of a large closed container and low-temperature air-cooling technology.

[0035] The above content is only a preferred embodiment of this utility model. For those skilled in the art, many changes can be made in the specific implementation and application scope based on the ideas of this technical content. As long as these changes do not depart from the concept of this utility model, they all fall within the protection scope of this patent.
