Description

Technical Field

[0001] This utility model relates to the field of electric heat tracing technology, and in particular to an explosion-proof and high-temperature resistant electric heat tracing cable. Background Technology

[0002] Electric heating tape is a strip-shaped heating device commonly used for insulation and freeze protection of equipment such as pipes and tanks. The working principle of electric heating tape is usually to convert electrical energy into heat energy through internal heating elements, thereby heating the object. When the electric heating tape is placed in a relatively static state, dust in the surrounding environment will gradually settle and adhere to its surface.

[0003] A search revealed that the utility model application with application number CN202121386634.7 provides a technical solution that includes an electric heating cable, a water-containing layer, a heat insulation layer, and a waterproof layer. The surface of the electric heating cable is provided with an explosion-proof layer. A sliding block is sleeved around the outer edge of the electric heating cable. A groove is formed inside the sliding block, and a slot is formed at the bottom of the groove. A scraper is slidably connected within the slot. A screw is threadedly connected to the outer edge of the sliding block through a pre-drilled threaded hole. This solution requires multiple screws to be turned when cleaning the surface of the electric heating cable, and the scraper is used to clean the dust from the surface. The process of turning the screws is very cumbersome, time-consuming, and labor-intensive. Utility Model Content
