Description

Technical Field

[0001] The utility model relates to a glass tempering furnace in the field of tempered glass, in particular to a low-pressure air grid swing device for the glass tempering furnace. Background Art

[0002] Wind spots often appear on raw glass after being treated in a tempering furnace. Wind spots are also called stress spots. The internal stress of tempered glass causes the glass to produce double refraction, which is an optical effect caused by grating diffraction. Stress spots appear under polarized or partially polarized light.

[0003] Uneven stress distribution during heating and cooling of tempered glass can cause wind spots. Ensuring uniform heating and cooling can effectively reduce the occurrence of wind spots.

[0004] However, the inventors of this application found that the above technology has at least the following technical problems in the process of implementing the technical solution of the invention in the embodiment of this application:

[0005] Heating factors: The glass is heated unevenly in the plane direction before being cooled and tempered in the tempering furnace. After the unevenly heated glass is cooled and tempered, the high temperature area will produce smaller compressive stress, and the low temperature area will produce larger compressive stress. Uneven heating will cause unevenly distributed compressive stress on the glass surface.

[0006] Cooling factor: The tempering process of glass is to heat and then cool rapidly. The cooling process is as important as the heating process to the formation of tempering stress. Uneven cooling of the glass in the plane direction before cooling and tempering will also cause uneven stress, just like uneven heating.

[0007] In the cooling section of the glass tempering furnace, measures can be taken to reduce the generation of wind spots. After the glass comes out of the furnace, the wind grille should be swung continuously, and the glass should be cleaned in time when it is broken in the wind grille. The wind pressure of the wind grille is determined according to the thickness of the tempered glass. Usually, when the wind pressure is 1000-3000Pa, it is a low-pressure wind grille; when the wind pressure is 8000-10000Pa, it is a high-pressure wind grille. Summary of the invention
