Description

Technical Field

[0001] This utility model relates to the field of ultra-high voltage cable processing technology, specifically a drying and conveying device for cross-linkable polyethylene insulation material used in ultra-high voltage cables. Background Technology

[0002] Ultra-high voltage cables generally have a voltage rating of 110kV and above, referring to cables with a voltage rating higher than 110kV. Cross-linked polyethylene (XLPE) insulated cables use a peroxide cross-linking method to transform the polyethylene molecules from a linear molecular structure to a three-dimensional network structure, changing it from a thermoplastic material to a thermosetting material. This increases the operating temperature from 70℃ to 90℃, significantly improving the cable's current-carrying capacity. The production process of XLPE insulated cables requires drying and conveying the cross-linkable polyethylene insulation material.

[0003] A search revealed a polyethylene insulation sheath material drying and conveying device disclosed in application number 202120136052.7. This device includes a support base with a support groove on one side of its top. A drying chamber is located at the top of the support base, with a feed pipe at the top of the drying chamber. The bottom end of the feed pipe extends into the interior of the drying chamber. A dryer is located at the top of the drying chamber, and a fan is located at one end of the drying chamber. A guide plate is located on one side of the inner wall of the feed pipe, and a second guide plate is located on the other side. An agitation mechanism is located inside the drying chamber below the second guide plate, and a discharge port is located at the bottom of the drying chamber. Through the cooperation of the dryer and the agitation mechanism, the conveyed material is effectively agitated, thereby achieving comprehensive drying of the material, improving drying efficiency and quality.
