Description

Technical Field

[0001] The utility model belongs to the technical field of dihedral insulation module foaming, and in particular relates to a dihedral insulation module foaming tooling for a deep cold storage and transportation system. Background Art

[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 dihedral insulation module is a dihedral insulation module structure with a folded angle formed by polyurethane foam combined with 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 dihedral insulation module is foamed by first bonding two separately foamed polyurethane plywood surfaces, then applying glue to the bonding points of the two insulation modules, and pressing them together with equipment. This method will greatly increase the production time of the dihedral insulation module and reduce production efficiency. For this reason, we propose a foaming tool for dihedral insulation modules for deep cold storage and transportation systems. Utility Model Content

[0014] Preferably, the top plate is provided with symmetrically distributed lifting ears.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. When the foaming tooling in the utility model is in use, first apply a release agent on the inner side of the bottom plate and the flat side plate to prevent the polyurethane from adhering to the flat side plate after foaming, which is helpful for demoulding after foaming. Then, the angled side plate and the flat side plate are fixed by the locking buckle assembly. Then, the plywood is placed on the inner side of the angled side plate. Then, the suction system tightly adsorbs the plywood on the inner side of the angled side plate through the adsorption port and the adsorption pore. Then, the angled fiberglass frame is placed between the angled side plate and the flat side plate in sequence. Then, a release agent is applied to the inner side of the top plate. Then, the top plate is placed on the angled side plate and the flat side plate, and fixed by the locking buckle assembly to form a polyurethane foaming molding space between the bottom plate, the angled side plate, the flat side plate and the top plate. Then, the sealing assembly is opened, and the polyurethane foaming material is injected into the polyurethane foaming molding space through the injection port. When the polyurethane foaming material is injected, the sealing assembly is opened. The injection port is sealed by the sealing component. As the polyurethane foams, the air in the polyurethane foaming molding space is gradually discharged from the exhaust hole, so that the polyurethane can fill the entire mold. Then the water pipe circulates the heated water through the water bath heating system to heat the polyurethane foam material in the polyurethane foaming molding space, accelerate the foaming and molding speed, and make the plywood and the polyurethane foam material directly form an integrated structure. Then, the locking component is opened, the angled side panels, the flat side panels and the top panel are removed, and the formed dihedral insulation module can be taken out. The dihedral insulation module with an angled angle can be directly obtained through this tooling, and there is no need to glue the plywood to the two outer sides of the dihedral insulation module again, which saves the production process and time cost of the dihedral insulation module, and at the same time improves the molding stability of the plywood and the dihedral insulation module, and improves the product quality of the dihedral insulation module.

[0017] 2. By rotating the sealing plate counterclockwise, the sealing plate can be released from the limit between the two fixing frames, and then removed from the injection port to facilitate injection. Then the middle of the sealing plate is placed on the injection port, and then the sealing plate is rotated clockwise to limit the position between the two fixing frames, so that the injection port can be sealed to achieve pressure foaming, which is convenient for injection and sealing of the injection port. At the same time, the structure is simple, easy to use, and reliable in sealing;

[0018] 3. The angled side panels, flat side panels and top panels can be locked and fixed by means of locking hooks and locking heads. The angled side panels, flat side panels and top panels can be quickly assembled and disassembled, thereby improving the production efficiency of the dihedral insulation module.
