Cooling air cooling system of shock cooling section of glass tempering furnace

Abstract

The invention belongs to the technical field of glass tempering and relates to a cooling air cooling system of a shock cooling section of a glass tempering furnace.The cooling system comprises a shock cooling section fan and a cooling device which provides a cooling air source for the shock cooling section fan, and the shock cooling section fan and the cooling system are arranged in a basement.The cooling air cooling system of the shock cooling section of the glass tempering furnace has the advantages that existing physical tempering technologies of the company are improved, and an original natural air cooling system is replaced with a basement cooling air cooling system, so that the strength of tempered glass is improved while the performance instability of physically tempered glass is avoided.Besides, the production cost is reduced, the yield of finished products is improved, and the application security and the reliability of down-stream products are improved; for example, when ultra-thin tempered glass is applied to a double glass component, the load capacity and the safe reliability of the component are enhanced.

Description

technical field [0001] The invention belongs to the technical field of glass tempering, in particular to a cooling system for cooling air in a quenching section of a glass tempering furnace. Background technique [0002] The existing physical tempered glass cooling method is air cooling. The original glass passes through the tempering furnace and then undergoes rapid air cooling through the quenching section. Finally, a stress layer is formed on the surface and inside of the glass, thereby improving the strength of the glass. However, in the prior art, due to the proximity of the cooling fan to the glass cooling section, there are defects and deficiencies in the cooling system of the cooling air in the quenching section of the glass tempering furnace, as follows: [0003] 1. Affected by the outside air temperature, when the tempering parameters are the same, the temperature difference between winter and summer causes the difference in the performance of tempered glass in dif...

AI Technical Summary

Problems solved by technology

[0003] 1. Affected by the outside air temperature, when the tempering parameters are the same, the temperature difference between winter and summer causes the difference in the performance of tempered glass in different seasons;

[0004] 2. The cooling fan is close to the glass cooling section. After the glass comes out of the furnace and passes through the cooling section, the ambient temperature rises, which causes the temperature of the fan suction port to rise and affect the cooling effect.
