Description

Technical Field

[0001] This utility model relates to the field of cryogenic medium storage and transportation equipment, specifically a cryogenic container with high safety. Background Technology

[0002] Cryogenic containers are a general term for equipment used to store and transport cryogenic liquids. They are conventionally categorized into small Dewar flasks, storage tanks, tank trucks, and tank ships. Industrially, liquefied gases stored and transported include liquefied natural gas, liquid oxygen, liquid nitrogen, liquid hydrogen, liquid helium, and liquid fluorine. Cryogenic containers (or cryogenic vessels for short) are usually named after the liquefied gas they store or transport; therefore, a high level of safety is required for cryogenic containers.

[0003] Existing patent document CN218409542U discloses a cryogenic container, including a base frame, a tank body, and a support assembly. When the rotating outriggers are rotated to a vertically released state, the base frame can be supported at different heights by adjusting the movement of the telescopic outriggers. This allows the chassis to extend under the base frame and support it, or allows the chassis to be moved out from under the base frame and supported on the ground. When the chassis transports the cryogenic container, the rotating outriggers are rotated to a retracted state, ensuring that the support assembly does not interfere with the transport of the cryogenic container. The cryogenic container is supported on the ground by the support assembly, facilitating quick installation and removal from the chassis. By adjusting and limiting the position of the telescopic outriggers relative to the rotating outriggers, the base frame can be supported at different heights, allowing frames of different heights to be extended to the bottom of the base frame. This enables the cryogenic container to adapt to the transportation of frames of different heights. However, the CN218409542U technology is prone to damage from collisions during operation, resulting in leakage of cryogenic solutions, low safety, and difficulty in providing buffer protection and thermal isolation for the device. Therefore, there is an urgent need for a cryogenic container with high safety. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a high-safety cryogenic container to solve the problems that existing high-safety cryogenic containers are easily damaged by collisions during use, causing leakage of cryogenic solutions, resulting in low safety, inconvenience in buffering and protecting the device, and inconvenience in thermally isolating the device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-safety cryogenic container, including an end cap, an inner tank installed at one end of the end cap, connecting blocks welded to the inner wall of the inner tank, an inner liner welded to the outer wall of the connecting blocks, and heat insulation cotton attached to the outer wall of the inner tank.

[0006] The outer wall of the insulation cotton is attached to the outer tank, and the outer wall of the outer tank is equipped with a limit frame. The inner wall of the limit frame is fixedly connected with a positioning rod, and the outer wall of the positioning rod is fixedly connected with a protective frame.

[0007] The inner wall of the protective frame is welded with springs, one end of each spring is welded with a buffer frame, a movable disk is installed at the lower end of the protective frame, the inner wall of each movable disk is fitted with a connecting bolt, and a fixing sleeve is fixedly connected to the outer wall of each connecting bolt.

[0008] Preferably, the outer wall of the inner tank is tightly fitted to the inner wall of the insulation cotton, and the diameter of the outer wall of the inner tank is smaller than the diameter of the inner wall of the insulation cotton.

[0009] Preferably, the outer tank is movably connected to the limiting frame, and the inner wall of the outer tank has an open design.

[0010] Preferably, the limiting frame is threadedly connected to the positioning rod, and the positioning rod is symmetrically arranged about the central axis of the limiting frame.

[0011] Preferably, the protective frame and the buffer frame are movably connected, and the buffer frames are arranged at equal intervals on the inner wall of the protective frame.

[0012] Preferably, the protective frame is engaged with the movable disk, and the inner wall of the movable disk has an open design.

[0013] Preferably, the movable disk is engaged with the connecting bolts, and the connecting bolts are arranged in a ring array on the inner wall of the movable disk.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model achieves a tight fit between the inner tank and the insulation cotton. When using the device, the inner tank and the insulation cotton facilitate thermal isolation of the device, increasing its usability.

[0016] 2. This utility model uses a limiting frame to allow the outer tank to move. When using the device, the outer tank provides collision protection for the interior. The multi-layered structure makes it less likely for low-temperature solutions to leak.
