[0002] The cryogenic storage and transportation system is used in large-scale liquefied natural gas transportation and storage. Its core feature is the use of special film materials and low-temperature insulation technology. The trihedron insulation module is a polyurethane special-shaped trihedron structure with a folded angle formed by polyurethane foaming and plywood. It is used in the insulation system of some liquid natural gas and liquid nitrogen storage tanks. It is one of the important components of film-type cryogenic storage tanks, which can greatly reduce the construction workload and shorten the construction period. It has the advantages of improving the cold preservation performance of film storage tanks and reducing the evaporation rate.

[0003] The existing trihedral insulation module foaming tooling for cryogenic storage and transportation systems adopts a polyurethane foaming mold to foam a polyurethane module, and then adheres plywood to the surface of the polyurethane to form a flat insulation module. Then, three flat insulation modules with oblique cuts on one side are pressed into a trihedral insulation module on a pressing tool, which leads to low production efficiency of the trihedral insulation module. For this reason, we propose a trihedral insulation module foaming tooling for cryogenic storage and transportation systems. Utility Model Content
