Description

Technical Field

[0001] The utility model relates to the technical field of low-temperature storage tanks, in particular to a storage tank with a protective structure. Background Art

[0002] Cryogenic and high-pressure liquid storage is a special storage method, which is mainly used to store cryogenic liquids, such as liquid nitrogen, liquid oxygen, liquid argon, etc. Cryogenic storage tanks are usually composed of inner tanks and outer tanks, with insulation materials filled in the middle.

[0003] Chinese patent number CN209340872U proposes a protective device for a medical oxygen cryogenic storage tank. Although a protective shell is detachably installed on the outer side of the cryogenic storage tank, and the protective shell is placed on the outer side of the cryogenic storage tank when the cryogenic storage tank is moved or transported, which can prevent the outer tank of the cryogenic storage tank from being damaged, the buffering protection effect of the protective structure is poor. When injecting materials into the tank, when liquid or solid materials are poured into the cryogenic storage tank, due to inertia, rapid flow and high-speed collision, a certain pressure and impact force will be generated, and this pressure and impact force will cause damage to the body of the cryogenic storage tank.
