Abstract

The invention discloses an inserting and pulling type low-temperature container. The inserting and pulling type low-temperature container comprises a refrigerator and a low-temperature container body.A first-stage cold cavity is placed in a first-stage cold screen of the low-temperature container body, an elastic round sleeve and a first-stage corrugated pipe are arranged on the top walls of thelow-temperature container body and the first-stage cold cavity correspondingly, the middle of the elastic round sleeve is fixedly provided with a first lower conduction block connected with the top wall of the first-stage cold screen, a second upper conduction block and a second lower conduction block are arranged on the bottoms of the elastic round sleeve and the first-stage corrugated pipe correspondingly in a seal manner, a first upper conduction block is arranged on a first-stage cold head of the refrigerator in a sleeving manner, a second-stage cold head of the refrigerator is used for driving the second upper conduction block and the second lower conduction block to be tightly attached, the refrigerator is mounted on the top wall of the low-temperature container body through an elastic supporting device, and the upper end of the elastic round sleeve is fixed to the elastic supporting device. When the elastic supporting device is loosened, the elastic supporting device is matchedwith the elastic round sleeve to enable the refrigerator to pop out of the low-temperature container body, and complete separation of the refrigerator and the low-temperature container body is achieved.

Description

technical field

[0001] The invention relates to a low-temperature device for refrigerating low-temperature items, in particular to a pluggable low-temperature container. Background technique

[0002] A pluggable cryogenic container is a device widely used in the field of superconducting magnets, such as in the field of transportation, such as: superconducting maglev trains, superconducting electric vehicles, superconducting electromagnetic propulsion systems for ships, etc.; Energy field, such as: flywheel energy storage, superconducting DC motor, superconducting generator, etc.; biomedical field, such as: nuclear magnetic imaging (MRI), nuclear magnetic resonance (NMR), etc.

[0003] A cryogenic container is a device used to hold a low-temperature medium (such as liquid nitrogen, liquid oxygen, liquid helium, etc.) to create a low-temperature working environment. When the temperature of the low-temperature medium stored in it drops to its phase transition temperature, there...
