Description

Technical Field

[0001] The utility model specifically relates to the technical field of cable protection pipe production, and particularly relates to a full-nitrogen vulcanization electric heating device for producing super wear-resistant and impact-resistant cable protection pipes. Background Technique

[0002] For wires and cables, in order to ensure their insulation, a rubber insulation layer structure is generally provided on the outer layer of the wires and cables; during the production and processing of wires and cables, the rubber insulation layer is generally sleeved around the core wire by an extrusion molding method, and the formed rubber insulation layer needs to be vulcanized through a vulcanization pipeline. During the vulcanization process of the wires and cables, high-temperature and high-pressure steam is introduced into the vulcanization pipeline, and the rubber insulation layer undergoes a chemical cross-linking reaction under the action of high temperature and high pressure, so that the rubber insulation layer plays an insulating role.

The upper side pipe body includes an upper side heat conduction plate, an upper side metal isolation layer, an upper side heat insulation and heat preservation layer, and an upper side metal protection layer that are sequentially stacked from the inside to the outside. The outer arc surface of the upper side heat conduction plate is provided with an upper side heating pipe clamping groove, and an upper side electric heating pipe is embedded and clamped in the upper side heating pipe clamping groove; the lower side pipe body includes a lower side heat conduction plate, a lower side metal isolation layer, a lower side heat insulation and heat preservation layer, and a lower side metal protection layer that are sequentially stacked from the inside to the outside.
