Problems solved by technology

[0002] At present, the traditional three-point support is adopted for cryogenic storage tanks, which are supported and fixed by three steel pipes and drawstring structures. The steel pipes and drawstrings of this structure are all stainless steel, and the thermal conductivity is large, which makes the evaporation rate of the cryogenic storage tank too high. , affecting the overall thermal insulation performance of the cryogenic storage tank, its use is limited, and it cannot be used in high-vacuum multi-layer thermal insulation cryogenic storage tanks

Abstract

The invention discloses a supporting device of an inner container in a low-temperature storage tank, which can decrease the evaporation rate and comprises a supporting pipe, an upper pipe seat and a lower pipe seat, wherein the upper pipe seat is arranged at the center of the bottom of the inner container, the lower pipe seat is arranged on a corresponding position on the inner wall of the shell of the storage tank and matched with the upper pipe seat, and both ends of the supporting pipe are respectively arranged in the upper pipe seat and the lower pipe seat. In the invention, the single supporting pipe is adopted for supporting, thereby greatly decreasing the heat conducting area, decreasing the evaporation rate, improving the heat insulating performance of the whole low temperature storage tank and enabling the structure to be used in a high-vacuum multilayer heat insulation low temperature storage tank.

Description

technical field [0001] The present invention relates to a cryogenic storage tank, in particular to a supporting device for an inner vessel in a cryogenic storage tank. Background technique [0002] At present, the traditional three-point support is adopted for cryogenic storage tanks, which are supported and fixed by three steel pipes and drawstring structures. The steel pipes and drawstrings of this structure are all stainless steel, and the thermal conductivity is large, which makes the evaporation rate of the cryogenic storage tank too high. , affecting the overall thermal insulation performance of the cryogenic storage tank, its use is limited, and it cannot be used in high-vacuum multi-layer thermal insulation cryogenic storage tanks. Contents of the invention [0003] A technical problem to be solved by the present invention is to provide a supporting device for the inner container in the cryogenic storage tank which can reduce the evaporation rate. [0004] In orde...
