Description

Technical Field

[0001] The utility model relates to the technical field of dewar tank transportation protection equipment, in particular to a protection structure for dewar tank transportation. Background Art

[0002] Dewar tank, also known as Dewar flask, is a high vacuum multi-layer insulated movable cryogenic liquid container. It adopts super vacuum insulation technology and is designed as a stainless steel pressure vessel. It is mainly used for the storage, transportation and use of cryogenic liquid gases such as liquid oxygen, liquid nitrogen, liquid argon or carbon dioxide. These containers are manufactured in accordance with DOT4L standards, ensuring the reliable and economical transportation and storage of cryogenic liquid gases, as well as on-site storage and supply in various application scenarios.

[0003] Since Dewar tanks are widely used in scientific research, medical treatment, industry and other fields, they need to be transported to the corresponding destination after the filling and production of Dewar tanks are completed.
