CONTAINER-TANK FOR LIQUID CRYOGENIC PRODUCTS Russian patent published in 2003 - IPC

FIELD: cryogenic engineering; transportation of liquid cryogenic products. SUBSTANCE: invention relates to transportation of cryogenic products, including liquefied natural gas. Proposed container-tank consists of frame, heat insulation, cylindrical barrel, two load-bearing belts with two support brackets on each belt. Barrel support units contain four deformation temperature compensators, each made in form of movable pair of dovetail type whose slider is rigidly coupled at one side through insulating lining with bracket connected by bolts with barrel load-bearing belt, and at other side is rigidly coupled with housing of hydraulic cylinder. Deformation temperature compensators are arranged with axes of movement (axes of hydraulic cylinders) in one load-bearing belt across axis of barrel, and other compensators arranged in second load-bearing belt are installed with axes of movement along diagonal of half-planes of barrel. Brackets with heat isolating linings are installed on frame in load-bearing belt area. Slots on said linings engage with alignment bosses of load- bearing belts. Proposed design makes it possible to decrease heat flow through load-bearing ties of barrel and frame owing to reduction of number of load-bearing ties between barrel and frame and installation of heat isolating linings in butt joints of barrel load-bearing belts and frame support units, and compensation of temperature deformations practically without increase of internal forces acting onto support units. EFFECT: provision of uniform distribution of external loads on load-bearing ties. 5 dwg
