Description

Technical Field

[0001] The utility model relates to the technical field of quick-freezing and refrigeration, in particular to a mobile ultra-low temperature quick-freezing and refrigeration device. Background Art

[0002] Transport media such as tuna are quick-frozen to minus 60 degrees Celsius and then transported and stored in an ultra-low temperature environment. In order to ensure the freshness of tuna as much as possible and maintain the high added value of the product, a low-temperature resistant refrigerated box is required for transportation.

[0003] In the prior art, the carriage of a truck is usually improved and transformed into a refrigerated cabinet. However, such a cabinet can only withstand a low temperature of about minus 20 degrees and is difficult to meet the storage conditions of tuna at minus 60 degrees Celsius.

[0004] Moreover, at a temperature of minus 60 degrees Celsius, thick frost will form inside the sealed box. Especially at the door position, due to the connection gap and large temperature difference, the sealed door will be tightly frozen and adhered to the inner wall of the box, resulting in the problem that it cannot be opened. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1 to 6 , the present invention provides a technical solution:

[0025] Embodiment 1: A mobile ultra-low temperature quick-freezing and refrigeration device, including a refrigeration box 1. The refrigeration box 1 is divided into a refrigeration inner cavity 2 and an equipment inner cavity 3 by a partition 4. The box body of the refrigeration box 1 is integrally formed by hot pressing a polymer polyester material, a polyurethane heat-insulating material, and high-strength fiberglass under vacuum. Adjacent box bodies are connected by a seamless bonding process and a metal-free heat bridge connection.

[0026] By setting an integrally formed fully enclosed hexahedron structure, the connection gaps generated between the box panels are avoided, the sealing performance of the refrigeration box is improved, and it is ensured that it can maintain the condition of minus 60 degrees Celsius. By setting the partition 4 to realize the inner cavity separation, the equipment and the refrigeration environment are relatively independent, avoiding mutual influence.

[0027] A stepped groove 11 is provided on one side of the refrigeration inner cavity 2. The refrigeration inner cavity 2 is sealed by a sealing door 9 pressed on the stepped groove 11. A sealing rubber strip 14 pressed on the stepped groove 11 is provided on the sealing door 9. An electric heating tape 10 is provided on the stepped end face of the stepped groove 11 facing the sealing rubber strip 14.

[0028] By setting the stepped groove 11, the sealing door 9 is not directly connected to the inner wall of the box body, but forms a vertical stepped surface connection and pressing, reducing the temperature difference. At the same time, an electric heating tape 10 is provided at the position connected to the sealing rubber strip 14. After refrigeration, the electric heating tape 10 is heated to achieve the purpose of thawing, facilitating the convenient opening and closing of the sealing door 9.

[0029] Embodiment 2: On the basis of Embodiment 1, forklift bottom grooves 8 are symmetrically provided on both sides of the bottom of the refrigeration box 1. By setting the forklift bottom grooves 8, the convenient connection with the forklift is realized, and thus the transportation and hoisting movement of the refrigeration box 1 are facilitated.

[0030] A refrigeration compression device is provided in the equipment inner cavity 3. A double-opening door 5 is provided at the front end of the equipment inner cavity 3. Three groups of exhaust fans 6 communicating with the equipment inner cavity 3 are installed at the upper end of the double-opening door 5. Louvers 7 are symmetrically provided on both sides of the equipment inner cavity 3, and the louvers 7 communicate with the equipment inner cavity 3.

[0031] By setting up the exhaust fan 6, rapid heat dissipation of the refrigeration equipment in the inner cavity 3 of the device is achieved, ensuring the normal operation of the device. By setting up the louvers 7, unilateral air intake is realized, achieving the circulation of internal and external airflows in and out.

[0032] On the outer side of the sealed door 9, there is a fixed rod 12 installed in a lifting manner, and on the outer wall of the refrigerating box 1, there is a fixed seat 13 that is cooperatively inserted with the fixed rod 12.

[0033] Through the cooperation of the fixed rod 12 and the fixed seat 13, the fixed rod 12 is inserted into the fixed seat 13, realizing the fixed closure of the sealed door 9.

[0034] A refrigeration machine evaporator is installed in the refrigerating inner cavity 2. The bottom plate of the refrigerating inner cavity 2 is installed with an aluminum guide rail. On the stepped groove 11, there is a pressure strip that cooperates with the sealing strip 14, and the electric heating tape 10 is arranged in the pressure strip.

[0035] By setting up a pressure strip that cooperates with the sealing strip 14, the sealing performance between the sealed door 9 and the inner wall of the box is further improved. Furthermore, the electric heating tape 10 is arranged in the pressure strip to realize interval heating, avoiding excessive heat deformation of the sealing strip 14 made of composite materials caused by direct heating.

[0036] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
