Adjustable tuyere mechanism of glass tempering furnace

Abstract

The invention relates to the field of glass physical tempering cooling, in particular to an adjustable tuyere mechanism of a glass tempering furnace. The mechanism comprises a plurality of air exhausts which are arranged up and down; each air row comprises a plurality of strip-shaped air nozzles which are arranged in parallel, and a plurality of air outlet holes are formed in the surfaces, facing the toughening furnace roller way, of the strip-shaped air nozzles; the two ends of each strip-shaped tuyere are each internally provided with a tuyere inner sealing plate, and the perforated faces of the tuyere inner sealing plates are parallel to the perforated faces of the strip-shaped tuyeres; and the tuyere inner sealing plate can translate or slide in the strip-shaped tuyere so as to control the opening and closing of air outlet holes in the strip-shaped tuyere and change the air outlet hole number of the strip-shaped tuyere. According to the size of glass, the number of actual air outlet holes of the strip-shaped tuyere is reasonably controlled through the tuyere inner sealing plate, so that the energy waste is reduced, and the tempering cost is reduced. Meanwhile, according to the structure, the blowing area is reduced, the wind power is more concentrated, the cooling wind pressure distribution is more uniform, and due to the fact that the blowing area is reduced, the heat dissipation space is enlarged, the heat dissipation time is shortened, and the efficiency is improved.

Description

technical field [0001] The invention relates to the field of glass physical tempering and cooling, in particular to an adjustable tuyere mechanism of a glass tempering furnace. Background technique [0002] Tempered glass belongs to safety glass and is a kind of prestressed glass. It is generally made by heating the pretreated glass original sheet in a tempering furnace until it is softened, and then cooling it uniformly and rapidly. It has high strength, heat shock resistance, and obtuse-angled fine particles after crushing will not harm the human body, so it is relatively safe. [0003] At present, the tempered glass equipment on the market cannot adjust the air nozzles used. When processing large-sized glass, all the air nozzles in the cooling section air exhaust will discharge air; when processing small-sized glass, all the air nozzles in the cooling section air exhaust will discharge air. . Therefore, the processing of large-size glass consumes as much energy as proce...

AI Technical Summary

Problems solved by technology

Therefore, the processing of large-size glass consumes as much energy as processing small-size glass, which wastes electricity and increases the cost of tempering. Moreover, due to the large blowing area, it is more difficult to achieve uniform wind pressure. It cannot be done according to the actual size of the processed glass. Make corresponding adjustments, while increasing the cost of tempering, it also affects the effect of glass tempering
