Description

A closed-loop control blowing system for a glass tempering unit

technical field

The utility model relates to the technical field of glass production and processing equipment, in particular to a closed-loop control blowing system of a glass tempering unit.

Background technique

The physical tempering of glass, its heating and quenching are very important to the tempering quality of the glass. The use of blower to blow and quench is an indispensable and important link in the tempering process, which directly affects the tempering quality and quality of the glass. In the past, the quenching air supply system mainly included fans, bellows, valves, air ducts, etc., in which the high-pressure centrifugal fan sent the quenched air to the bellows and air bag for diffusion and pressure equalization and diversion through the air ducts, valves, etc., and then Through the pressure equalization and diversion of the bellows and the wind bag, the quenching air is finally sent to the quenching air knife group close to the glass surface for blowing, quenching and tempering. The wind pressure of the quenching medium often reaches tens of thousands of pascals. Considering the space layout of the workshop and the loss of the fan, the air duct system should be made as short as possible. Due to the existence of the air box with pressure splitting effect, many air knife groups reaching the glass surface, the air pressure of the air knife group is not uniform. The effect of pressure equalization, then the quality of the final tempered glass is not perfect. The above-mentioned air supply system is also relatively cumbersome, takes up a lot of space, and the adjustment of the air supply system is also more troublesome. The cost of forming the air supply system is relatively high, and the installation of the components forming the air supply system is also time-consuming and laborious. Labor costs are expensive, transportation costs, etc. high.
