Embodiment Construction

[0023] The present invention will be further elaborated below with reference to the accompanying drawings.

[0024] see figure 2 , a cryogenic storage tank 100 provided by the present invention includes: a body 1 and a support 2 arranged at the bottom of the body 1 for supporting the body 1 . The body 1 includes an inner container 11 , an inner container supporting device 13 and an outer shell 12 , and a gap 15 is provided between the inner container 11 and the outer shell 12 .

[0025] Specifically, the inner container 11 includes an inner cylinder 111 and two inner seals 112 respectively disposed at both ends of the inner cylinder 111 , and the outer shell 12 includes an outer cylinder 121 and outer seals 122 respectively disposed at both ends of the outer cylinder 121 .

[0026] The bottom of the shell 12 is provided with a through hole, the bottom end of the inner container supporting device 13 passes through the through hole downwards, and the top end of the inner conta...

Abstract

The invention relates to a low-temperature storage tank which comprises a body and a support arranged at the bottom of the body and used for supporting the body. The body comprises an inner container, an inner container supporting device and a shell, wherein the inner container and the shell are spaced, through holes are formed in the bottom of the shell, the bottom end of the inner container supporting device downwards penetrates out of the through holes, and the top end of the inner container supporting device is arranged in the space to support the inner container. The body and the support of the low-temperature storage tank are integrated, the through holes are formed in the bottom of the shell, the bottom end of the inner container supporting device downwards penetrates out of the through holes to be connected to the support, heat transfer routes of the inner container supporting device are added, heat conduction is reduced, and therefore the static evaporation rate of the low-temperature storage tank is reduced, and the heat insulation performance of the low-temperature storage tank is improved; the total height of the low-temperature storage tank is lowered, and the manufacturing cost is lowered; and besides, the low-temperature storage tank is simple in structure and can be applied to low-temperature tanks with the medium volume.

Description

technical field [0001] The invention relates to the technical field of pressure vessels, in particular to a low-temperature storage tank. Background technique [0002] Cryogenic storage tank refers to a double-layer structure container that stores liquids with a boiling point temperature lower than -150°C (such as liquid nitrogen, liquid oxygen, liquid argon, liquefied natural gas, etc.). [0003] Such as figure 1 As shown, the cryogenic storage tank 100 includes an inner container 11 and an outer shell 12 , and a space is provided between the inner container 11 and the outer shell 12 . The cryogenic storage tank 100 is fixed upright by the support 2 , and the inner container 11 is fixed by the steel pipe 13 at the bottom and suspended by the strap structure 16 at the top. The steel pipes and drawstrings in the supporting device of the inner container are made of stainless steel, which has a large thermal conductivity, which leads to a relatively high static evaporation ra...
