Description

Technical Field

[0001] The utility model relates to the technical field of glass production, in particular to a self-cleaning glass tempering furnace. Background Art

[0002] Tempered glass is a safety glass. Tempered glass is actually a prestressed glass. In order to improve the strength of the glass, chemical or physical methods are usually used to form compressive stress on the glass surface. When the glass is subjected to external force, the surface stress is first offset, thereby improving the bearing capacity and enhancing the glass's own resistance to wind pressure, cold and heat, impact, etc. During the production process of tempered glass, a tempering furnace is required to heat the glass evenly. After heating, the glass surface needs to be cleaned. Traditional self-cleaning glass tempering furnaces usually use electric or pneumatic robotic arms and other equipment to regularly swing, sweep, and clean the surface of the object being cleaned. Traditional self-cleaning glass tempering furnaces have a small cleaning area and cannot be cleaned in all directions, which can easily lead to small areas that are difficult to clean thoroughly. For this reason, we propose a self-cleaning glass tempering furnace. Utility Model Content
