AI Technical Summary
Existing electric kettles and rice cookers have heating plates with short lifespans and high costs. In particular, electric kettles using recrystallized silicon carbide heating plates have excessively high power, while aluminum heating plates in rice cookers cannot use recrystallized silicon carbide, resulting in poor equipment performance and cost.
A basalt ceramic fiber heating wire coated with recrystallized silicon carbide was prepared using a device that combines an oxyhydrogen flame heating nozzle and a graphene powder silicone rubber roller. The basalt ceramic fiber heating wire that can be coated with silicon carbide powder at high temperatures was then prepared, and graphene was covered on an insulating ceramic disk to form a heating disk.
It achieves uniform coating and insulation treatment of silicon carbide powder at high temperatures, improving the durability and safety of the heating wire, making it suitable for high-power electric kettles and rice cookers, and reducing costs.

Abstract
Description
Technical fields:
[0001] This invention relates to a device for manufacturing basalt ceramic fiber heating wires encapsulated with recrystallized silicon carbide. Background technology:
[0002] The recrystallized silicon carbide heating element used in electric kettles is made by spraying recrystallized silicon carbide onto a ceramic sheet and then covering it with an insulating material. Electric kettles have a power rating exceeding 1.5 kilowatts. Rice cookers, on the other hand, have a smaller heating element with a power rating of only 300 watts. They cannot use recrystallized silicon carbide heating elements and must use aluminum heating elements with tungsten filaments. However, the tungsten filaments in aluminum heating elements burn out easily, resulting in a shorter lifespan and higher cost compared to recrystallized silicon carbide heating elements. Summary of the Invention:
[0003] The equipment for manufacturing basalt ceramic fiber heating wires wrapped with recrystallized silicon carbide consists of a silicon carbide horn nozzle heated by an oxyhydrogen flame, a rectangular tube with several windows on each side, several basalt ceramic fiber filament rolls, electrically operated silicone rubber rollers containing graphene powder, electrically operated reciprocating silicone rubber rollers containing graphene powder, and an electric winch for the basalt ceramic fiber heating wires wrapped with recrystallized silicon carbide. A rectangular tube with several windows on each side is vertically installed below the oxyhydrogen flame heated silicon carbide horn nozzle. Outside each window of the rectangular tube, there is a set of electrically operated silicone rubber rollers containing graphene powder and a set of electrically operated reciprocating silicone rubber rollers containing graphene powder. The basalt ceramic fiber filaments, drawn from the several basalt ceramic fiber filament rolls, pass through the gap between the first set of electrically operated silicone rubber rollers containing graphene powder and the electrically operated reciprocating silicone rubber rollers containing graphene powder. Basalt ceramic fiber filaments emerging from the gap between the first set of electrically operated silicone rubber rollers containing graphene powder and the second set of electrically operated silicone rubber rollers containing graphene powder pass through the gap between the second set of electrically operated silicone rubber rollers containing graphene powder and the third set of electrically operated silicone rubber rollers containing graphene powder, and so on, until the gap between the last set of electrically operated silicone rubber rollers containing graphene powder and the third set of electrically operated silicone rubber rollers containing graphene powder. Several basalt ceramic fiber heating wires wrapped with recrystallized silicon carbide emerging from the gap between the last set of electrically operated silicone rubber rollers containing graphene powder and the third set of electrically operated silicone rubber rollers containing graphene powder are wound onto an electric winch wrapped with recrystallized silicon carbide. The shaft of the electric winch wrapped with recrystallized silicon carbide has several winches.

It is then ignited by an electronic spark plug. Oxygen gas from the anode of the water electrolysis tank is compressed by an oxygen compressor and then ejected from the interlayer oxygen gap of the silicon carbide horn nozzle 1 heated by an oxyhydrogen flame, supporting hydrogen combustion. Silicon carbide powder exiting from the curved funnel tube of the silicon carbide powder funnel is inclined downwards and ejected by the hydrogen combustion flame. The 6000°C oxyhydrogen flame heats the silicon carbide powder to over 2200°C, melting it into droplets that are ejected from the silicon carbide horn nozzle heated by the oxyhydrogen flame.

Oxygen gas from the anode of the water electrolysis tank is compressed by an oxygen compressor and ejected from the interlayer of the oxyhydrogen flame-heated insulating ceramic horn nozzle, supporting the hydrogen combustion. Silicon carbide powder from the curved funnel of the insulating ceramic powder funnel is tilted downwards and ejected by the hydrogen combustion flame. The 6000°C oxyhydrogen flame heats the insulating ceramic powder to over 1500°C, melting it into droplets that are ejected from the oxyhydrogen flame-heated insulating ceramic horn nozzle 1, covering the basalt ceramic fiber heating wire wrapped with recrystallized silicon carbide in the spiral grooves of the insulating ceramic disc. Then, a layer of graphene is applied and heated to over 400°C to solidify the graphene, forming the heating plate for a rice cooker. Attached image description:
