Description

Technical Field

[0001] The utility model relates to the technical field of glass production, in particular to a tempered glass drying device. Background Art

[0002] Glass is mainly formed by melting silicates and other oxides. It is widely used in various buildings to block wind and transmit light. Glass melts into liquid at high temperature, and then forms an amorphous solid structure during rapid cooling. Tempered glass is glass with compressive stress on the surface, also known as strengthened glass. During the manufacturing process, tempered glass usually contains a certain amount of moisture. Generally, the moisture is removed by drying to prevent the tempered glass from bursting during heating or use. At the same time, the residual stress in the glass is released, which improves the strength and heat resistance of the tempered glass. If the tempered glass is stacked horizontally after production, the lower glass will be subjected to greater pressure from the upper glass, resulting in stress concentration and increasing the risk of glass breakage. Therefore, tempered glass is generally stored vertically.

[0003] The Chinese utility model patent with the authorization announcement number CN221349639U discloses a glass drying device for glass production, which transports and heats the glass in a contact manner by rotating the electric heating roller. In the above scheme, the glass can only enter the drying chamber horizontally, which is not applicable to the glass generally stored vertically; the energy consumption is high and the drying effect is poor, and the heating of the glass surface is uneven, which can easily cause damage to the inside of the glass. Utility Model Content
