Description

Technical Field

[0001] The present invention relates to the technical field of cable production, and more specifically, the present invention relates to a gas-phase cooling device for extruded insulation layers in cable production. Background Art

[0002] As a carrier for power transmission, cables play an important role in power transmission. The newly produced cables are in a high-temperature state and cannot be subjected to subsequent operations. To improve work efficiency, it is necessary to cool the cables; For example, a cooling device for wire and cable processing described in the patent with the patent publication number CN219534152U clamps the cable through two upper and lower limiting wheels, and the cable passes through a cooling pipe for cooling, but it cannot filter the harmful gases generated by the high-temperature cable. Prolonged exposure to this working environment is harmful to human health; For example, a cooling device for cables described in the patent with the patent publication number CN222088344U cools the high-temperature cables and absorbs the harmful gases emitted by the high-temperature cables, protecting the physical health of workers without affecting the functions. However, in the long term, the inner wall of the conduit used to cool the cable insulation layer in the above patent documents will accumulate impurities such as dust and dirt inside the device. These impurities hinder air flow and reduce the heat dissipation effect. Regular maintenance and cleaning can remove these impurities to ensure that the air-cooling device can continuously and effectively dissipate heat and prevent the cable insulation layer from being damaged due to overheating. However, when cleaning the above conduit, the conduit also needs to be disassembled and cleaned, and the maintenance process is too cumbersome to conveniently complete the cleaning process of the conduit; At the same time, in the above patents, some gases will still overflow from both sides of the conduit, and a water mist barrier cannot be formed on both sides of the conduit, which not only reduces the overflow of gases on both sides of the conduit, but also accelerates the cooling of the extruded insulation layer cable and improves the cooling efficiency; In view of the above technical defects, a solution is provided herein. Summary of the Invention
