CRYOCONTAINER FOR STORAGE AND TRANSPORTATION OF LIQUIDS IN CRYOGENIC STATE Russian patent published in 2024 - IPC F17C3/06 F17C3/08 

FIELD: transportation; storage.

SUBSTANCE: invention relates to cryocontainer for storage and transportation of liquids in cryogenic state. Container is intended for storage and transportation of cryogenic liquids in small doses from cryogenic container to direct consumer and can be used in industrial, transport, laboratory and medical applications of cryogenic liquids. Design of the multifunctional cryocontainer includes an external housing having the shape of a cylinder with elliptical bottoms and containing at least one coaxial heat-insulating shell and an internal housing of a similar shape. In the space between the outer housing and the heat-insulating shell, as well as between heat-insulating shell and inner housing permeable stiffening ribs of annular or arched shape, unions for loading and unloading of liquid in cryogenic state, unions for evacuation of insulation spaces and unions for operation and maintenance of cryocontainer, medium control sensors are installed in insulating spaces, inner casing and chamber of unions, safety valves for inner casing, heat-insulating shells and chambers of unions. Space between the outer housing and the heat-insulating shell, as well as between the heat-insulating shell and the inner housing, is evacuated through evacuation unions. Inner housing in working condition is filled with liquid through unions for loading and unloading of liquid in cryogenic condition. All the unions are grouped into a nozzle chamber with a hinged or detachable heat-insulating cover, the walls of the nozzle chamber are heat-insulated and coupled with the outer housing, heat-insulating shells and the inner housing, wherein said chamber is evacuated after loading operation.

EFFECT: minimization of heat conductivity of the structure as a whole during storage and transportation of cryogenic liquid from several litres to several hundreds of litres per water and reduction of dimensions and weight of the structure, low content of gas in the space between heat-insulating shells and possibility of using low-efficiency pumps to create vacuum.
