Cryogenic container insulated by glass beads

Abstract

The invention provides a cryogenic container insulated by glass beads, which comprises an outer tank of the cryogenic container, the glass beads and an inner tank of the cryogenic container, and the glass beads are filled in a gap between the outer tank of the cryogenic container and the inner tank of the cryogenic container; wedge-shaped metal connecting plates are arranged at the two ends of the inner side of the cryogenic container outer tank; concave grooves are formed in the left side and the right side of the cryogenic container inner tank; and the wedge-shaped metal connecting plate is movably clamped in the concave groove. The glass beads provided by the invention are used in a cryogenic container to reduce the evaporation rate and enhance the strength of a tank body, and the glass beads can be laid in vacuum; the heat insulation effect of the equipment is guaranteed, the use reliability of the equipment is improved, the manufacturing difficulty is reduced, the manufacturing period is shortened, the overall size of the equipment is reduced, the manufacturing cost is saved, and the operation process is optimized; and the deformation of the inner tank is also reduced by filling and insulating the glass beads.

Description

technical field [0001] The invention belongs to the technical field of low-temperature solution storage equipment, and in particular relates to a cryogenic container insulated with glass microbeads. Background technique [0002] A general cryogenic container includes an inner cylinder, an outer cylinder and a head, and a certain vacuum state is required between the inner cylinder and the outer cylinder. In order to achieve a suitable vacuum degree, the vacuum is usually achieved by the method of long-term evacuation of the interlayer, but the thermal insulation material of the interlayer and the material of the manufacturing equipment will overflow with trace gas and moisture, which will slowly reduce the vacuum degree. In order to maintain a suitable vacuum degree between the inner and outer cylinders, the cryogenic container usually has an adsorption device, which includes a low-temperature adsorption material and an adsorption chamber for storing the adsorption material, ...

AI Technical Summary

Problems solved by technology

However, the existing cryogenic container adopts high vacuum + cold shield heat insulation, and a cold shield needs to be installed between the inner and outer tank interlayers. The construction process is more complicated and the overall volume of the equipment is too large, and additional holes need to be made on the outer tank, which increases the equipment. The risk of cold leakage during use, and during the use of the equipment, it is necessary to always fill the cold screen with refrigerant, which increases the operating cost and also increases the complexity of the equipment, making the manufacturing period of the equipment too long
