Fixing device for thermal insulation material on inner liner of container in high vacuum multi-layer thermal insulation structure

Abstract

The invention relates to a fixing device for a thermal insulation material on the inner liner of a container in the high vacuum multi-layer thermal insulation structure, which comprises a hole type thermal insulation strip and a needle type thermal insulation strip, wherein a plurality of holes are arranged on the hole type thermal insulation strip, a plurality of bulges are arranged on the needle type thermal insulation strip, the needle type thermal insulation strip is wound on the surface of the inner liner, the bulges are outward, the hole type thermal insulation strip is matched with thebulges of the needle type thermal insulation strip through the holes so as to be wound on the needle type thermal insulation strip, and the winding direction of the needle type thermal insulation strip is vertical to that of the hole type thermal insulation strip. Through the mutual buckling of the hole type thermal insulation strip and the needle type thermal insulation strip, the hole type thermal insulation strip and the needle type thermal insulation strip are wound on the inner liner of the container in both the transverse direction and the longitudinal direction in a mutual restraint manner, and the bulges are utilized for fixing a plurality of layers of the thermal insulation material of the inner liner and an outer layer, thereby solving the problem that the thermal insulation material skids relative to the cylinder body of the inner liner of the steel container due to inertia during the transportation process of the sealed thermal insulation container for storing cryogenic liquid.

Description

technical field [0001] The invention relates to a heat insulating material fixing device used on the inner liner of a high-vacuum multi-layer heat insulating structure container. Background technique [0002] At present, the high-vacuum multi-layer heat-insulation structure container used for storing cryogenic liquids is formed by winding multi-layer heat-insulation materials on the inner liner, bonding and bundling them, and putting on the outer liner. The thermal insulation material is usually composed of low-temperature thermal insulation paper and aluminum foil or aluminized polyester film. Chinese patent CN101058209A discloses a low-temperature thermal insulation paper and composite thermal insulation material for sealing thermal insulation containers. [0003] Containers in transit are often loaded horizontally on vehicles, and liquids are often not completely filled with airtight, insulated containers. Since the multi-layer insulation material is only continuously wo...

AI Technical Summary

Problems solved by technology

Since the multi-layer insulation material is only continuously wound on the inner tank, when the vehicle accelerates and decelerates, the existing heat insulation container wrapped with the insulation material tends to have a different shape relative to the inner tank due to inertia. degree of positional slippage
