Glass tempering air-cooling device

Abstract

The invention relates to equipment for producing tempering glass, in particular to a curved surface tempering glass blowing device which comprises a lower air flue, a lower wind box, an upper wind box, an upper air flue, a lower wind box lifting device and an upper wind box lifting device. The curved surface tempering glass blowing device is characterized in that surfaces of the lower wind box and the upper wind box, which are back-to-back, are respectively provided with a connecting hole connected with the upper air flue and the lower air flue; and surfaces of the lower wind box and the upper wind box, which mutually correspond, are air-out surfaces which are provided with at least 100 air outlets. The air outlets are respectively provided with a blowing nozzle. The invention has the remarkable advantages that: the air-out surfaces avoid reflective exhaust of air blowing to glass so as to realize four-side exhaust to ensure that the cooling temperature on the surface of the glass is uniform, and the glass tempering quality is improved; smooth wind path, good blowing effect and high wind energy utilization ratio are achieved; and the curved surface tempering glass blowing device has reasonable structure, low cost, convenient maintenance and long service life.

Description

technical field [0001] The invention relates to equipment for producing tempered glass, in particular to a blowing device for curved tempered glass with low cost and good use effect. Background technique [0002] As we all know, in order to increase the strength of some glass products, especially the glass for automobiles, glass products need to be tempered. When glass is tempered in a glass horizontal tempering furnace, the glass needs to be blown and cooled by an air cooling device. The existing air cooling device It is composed of lower air duct, lower air box, lower air grille, upper air grille, upper air box, upper air duct, lower air grille and upper air grille lifting device. There are at least 50 ventilation holes on the opposite sides of the lower air box and upper air box. Connected with the air duct, at least 100 air grilles are arranged on the opposite side of the lower air box and the upper air box. This blowing device has following deficiencies: the one, compl...

[0002] As we all know, in order to increase the strength of some glass products, especially the glass for automobiles, glass products need to be tempered. When glass is tempered in a glass horizontal tempering furnace, the glass needs to be blown and cooled by an air cooling device. The existing air cooling device It is composed of lower air duct, lower air box, lower air grille, upper air grille, upper air box, upper air duct, lower air grille and upper air grille lifting device. There are at least 50 ventilation holes on the opposite sides of the lower air box and upper air box. Connected with the air duct, at least 100 air grilles are arranged on the opposite side of the lower air box and the upper air box. This blowing device has the following deficiencies: first, the structure is complicated and the manufacturing cost is high; second, the use cost is high, the maintenance cost is high, and the energy consumption is high;
