Description

Technical Field

[0001] The utility model relates to the technical field of heat preservation material pouring, in particular to a heat preservation material pouring device for a heat preservation pipeline. Background Art

[0002] Polyurethane thermal insulation pipe is the most common thermal insulation pipe at present. Polyurethane foam thermal insulation pipe is usually made by directly pouring foaming slurry between the inner pipe and the outer pipe to form foam in one time. The pouring of foaming slurry is usually completed by a high-pressure pouring machine. The current common high-pressure pouring machine is composed of a bucket for holding pouring raw materials, a pump for conveying pouring raw materials, and a pouring head for mixing pouring raw materials and injecting pouring slurry between the inner pipe and the outer pipe. When using this high-pressure pouring machine, the pouring head is usually held manually and one end of the pouring head is inserted into the pouring hole opened in the outer pipe. However, some insulation pipes are relatively large in length and diameter, so the pouring head for pouring alone can only pour the foam evenly on one side of the inside of the insulation pipe. Moreover, because the foam will be viscous after pouring, the range of foam flow inside the insulation pipe will also be relatively small, which can easily lead to cavities and holes in the insulation pipe produced and processed.

[0003] The patent publication number is CN220482364U, and the patent name is "A high-pressure pouring machine for an insulated pipe". The technical solution disclosed in the patent solves the above-mentioned technical problems. However, when the diameter of the insulated pipe changes, it is not convenient to adjust the position of the pouring pipe as needed, and the specifications of the two hoops need to be replaced again, and the overall adaptability is poor.
