Description

Technical Field

[0001] The utility model relates to the technical field of polyethylene outer protective pipe production, in particular to a drying and cooling device for polyethylene outer protective pipe production. Background Art

[0002] Polyethylene, referred to as PE, is a thermoplastic resin obtained by polymerization of ethylene monomers. In industry, it also includes copolymers of ethylene and a small amount of a-olefins. Polyethylene is odorless, non-toxic, feels like wax, and has excellent low-temperature resistance (the lowest operating temperature can reach -100 to -70°C). Polyethylene is mostly used in the production of pipelines. When producing polyethylene outer protective pipes, they need to be dried and cooled.

[0003] The current drying method usually uses hot air for drying. However, since the polyethylene material is too concentrated, it is difficult for hot air to fully dry all the polyethylene particles.
