Glass toughening and quenching device adopting mixed gas cooling

Abstract

The invention discloses a glass toughening and quenching device adopting mixed gas cooling. The glass toughening and quenching device comprises an air grid, an upper air pipe module and a lower air pipe module are oppositely arranged on the upper inner wall and the lower inner wall of the air grid, each of the upper air pipe module and the lower air pipe module is provided with multiple rows of air pipes, and each air pipe comprises a compressed air channel located on the inner side and a fan air channel located on the outer side; a plurality of air nozzles are distributed in the length direction of the air pipe at intervals and communicated with the compressed air channel. The upper air pipe module and the lower air pipe module each comprise z air pipe sets composed of multiple rows of air pipes. The air nozzles corresponding to the air pipes of the same air pipe group form a plurality of air nozzle groups; the two air nozzle sets corresponding to every two adjacent air pipe sets deviate by xmm, and every two adjacent air nozzle sets deviate by ymm. According to the glass toughening and quenching device with adopting mixed gas cooling function, the defect that the flow of cooling air is small is overcome, and the cooling air can be uniformly sprayed to the surface of glass, so that the glass toughening efficiency and quality are improved.

Description

technical field [0001] The invention relates to the technical field of tempered glass production, in particular to a mixed air-cooled glass tempering and quenching device. Background technique [0002] The principle of the glass physical tempering method is to heat the glass to a suitable temperature and then cool it rapidly, so that the glass surface shrinks sharply and generates compressive stress, while the middle layer of the glass cools slowly, and it is too late to shrink, so the tensile stress is formed, so that the glass obtains higher strength. . Generally speaking, the higher the cooling intensity, the greater the glass strength. In the tempering process of glass, heating and cooling are the most critical and important links. [0003] The tempered glass cooling device at the present stage has the disadvantage of a small flow of cooling air, which cannot cool the glass quickly, and the cooling air cannot be evenly sprayed on the surface of the glass, which affects...
