Abstract
The invention discloses a flat glass tempering apparatus, which includes a glass plate heating furnace and a glass plate tempering unit composed of a roller way and an air grid. Between the heating furnace and the tempering unit, a through-type glass plate pre-moulding chamber is arranged, wherein the internal temperature of the pre-moulding chamber is lower than external environmental temperature. When high-temperature softened glass plates pass through the pre-moulding chamber, the pre-moulding chamber pre-cools the glass plates by means of the internal low-temperature environment therein, thereby hardening the glass plates, so that the capability of resisting deformation due to air pressure of the glass plate in the follow-up tempering unit. In the apparatus, by means of addition of the pre-moulding chamber before the tempering unit, the high-temperature softened glass plates are pre-cooled, thereby improving the rigidity of the glass plates and improving the capability of resisting vibration deformation due to the air pressure of the glass plate in the tempering unit, so that the flat tempered glass is improved in waviness.
Description
Technical field
The present invention relates to a kind of flat glass toughening device.
Background technology
As shown in Figure 1, the tempering unit that existing flat glass toughening device generally includes glass plate heating furnace and is made up of air grid and roller-way, wherein, 1 is glass plate heating furnace, and 2 is roller-way, and 3 is air grid, and 4 is sheet glass.During work, first in process furnace, sheet glass is heated, then by roller-way, sheet glass is transported to tempering unit from process furnace, utilize the air grid of roller-way upper and lower in tempering unit to blow sheet glass, realize the cooling tempering to sheet glass.
Because the tempering of sheet glass is completed by air-cooled, therefore the wind of air grid blowout must have enough wind speed and air quantity, with the speed of cooling making sheet glass reach enough, realizes tempering.And along with the minimizing of sheet thickness, its speed of cooling reached needed for tempering also improves, and for this reason, then needs wind speed and the air quantity of corresponding raising cooling air thereupon.As when using identical air grid, during the thick sheet glass of tempering 6mm, in air grid, cooling air pressure only needs 1600 ~ 3000Pa, during the thick sheet glass of tempering 3mm, the pressure of cooling air in air grid is then needed to bring up to 14000Pa, for the sheet glass that thickness reduces further, then need the pressure improving cooling air further.
The wind of air grid blowout, while realization is to sheet glass cooling, also produces blast in glass pane surface.As shown in Figure 2, when the front end of the sheet glass 4 exported from process furnace 1 to advance between the first pair of air grid 3 be oppositely arranged up and down and is in vacant state, cooling air, while the cooling air cooling blown out by air grid 3, also will be born and act on the impact of the blast of glass pane surface in the front end of sheet glass 4.Although air grid about 3 is arranged in pairs, the nozzle up and down on air grid 3 or spout are difficult to accomplish to aim at completely; By cooling air transfer line windage effect, also can there is minute differences in the pressure of the cooling air in upper and lower air grid 3; By the restriction of installing space, the nozzle on upper and lower air grid 3 or spout are also difficult to accomplish identical apart from the distance on sheet glass 4 surface; And, no matter the cooling air carried by blower fan itself is pressure or flow also there is certain pulsation; In addition, sheet glass 4 itself also has certain gravity; Thus, sheet glass 4 is difficult to the stress balance maintaining vertical direction under the effect of cooling air blast, and the sheet glass 4 of hot mastication state is under the effect being subject to power up or down, to be easy to occur vibration and cause distortion, especially the front and rear of the throughput direction of sheet glass 4, this distortion caused because of vibration is more outstanding.Therefore, the defect that the above-mentioned prior art dull and stereotyped toughened glass ubiquity percent ripple as shown in Figure 3 of processing is low.
Summary of the invention
For the deficiency that prior art exists, the object of the present invention is to provide a kind of flat glass toughening device, this device carries out pre-cooled by increasing presetting device before tempering unit to the sheet glass of hot mastication state, improve the rigidity of sheet glass, improve the ability that sheet glass resists the sheet glass vibration distortion caused because of blast in tempering unit, improve the percent ripple of dull and stereotyped toughened glass.
For achieving the above object, the sheet glass tempering unit that flat glass toughening device of the present invention comprises glass plate heating furnace and is made up of roller-way and air grid, wherein, formula sheet glass pre-setting room is also provided with between described process furnace and described tempering unit, the internal temperature of pre-setting room is lower than ambient temperature, along with the sheet glass of hot mastication state passes through from pre-setting room, pre-setting room utilizes its inner cryogenic environment to carry out pre-cooled to sheet glass, sheet glass is hardened, to improve the ability that sheet glass resists the distortion caused because of blast in follow-up tempering unit.
Further, the temperature of described pre-setting indoor is-5 DEG C ~-30 DEG C.
Further, described pre-setting indoor are provided with roller bed type sheet glass e Foerderanlage.
Further, described pre-setting indoor are provided with air flowing type glass plate e Foerderanlage.
Further, described pre-setting room provides cold wind by external refrigeration system, to maintain its low temperature environment.
Further, described pre-setting indoor are also provided with air grid, and what this air grid blew out is gentle breeze, and the blast that this gentle breeze acts on glass pane surface is enough little, to avoid because blast causes sheet glass to be out of shape.
Further, described air grid is simultaneously by external refrigeration system air feed.
Further, described air grid is by blower fan air feed, and this blower fan sucks the cryogenic gas of pre-setting indoor, is then blown into air grid, so in the indoor formation cryogenic gas circulation of pre-setting.
The present invention is by carrying out pre-cooled sizing to the sheet glass of hot mastication state, improve the rigidity of sheet glass, improve the ability that sheet glass resists the vibration that blast causes in tempering unit, reduce sheet glass in tempering unit because of the distortion that blast causes, improve the quality of dull and stereotyped toughened glass.
The percent ripple of dull and stereotyped toughened glass thick to existing common 4mm, 5mm, 6mm can not only be brought up to 0.07mm/300mm by 0.15mm/300mm by the present invention, and to be particularly suitable for thickness be the tempering compared with thin glass plate such as 3mm, 2mm.
