Specific embodiment
Below in conjunction with glass tempering system of processing and its glass air cushion heater of the drawings and Examples to the present invention
It is described in further detail.
Refer to Fig. 1, a kind of glass tempering system of processing 10 of the embodiment of the present invention, which is used for tempering processing glass 20.
It is upper sheet devices 11 that glass tempering system of processing 10 includes being sequentially connected, preheating device 12, glass air cushion heater 13, quick
Chiller 14 and lower sheet devices 15.Refer to Fig. 2, glass air cushion heater 13 include shell 131, upper heating unit 132,
Air supporting warm table 133, blower fan 134, the first elevator 135 and the second elevator 136.There is in shell 131 accommodating chamber 1312.On
Heating unit 132, air supporting warm table 133 and blower fan 134 are located in accommodating chamber 1312.Air supporting warm table 133 has upper surface
1332, upper surface 1332 is provided with multiple ventholes 1334.Upper heating unit 132 is located at the top of upper surface 1332.Blower fan 134
With air vent 1342 and air inlet 1344.From 1342 expellant gas of air vent the going out from air supporting warm table 133 of blower fan 134
Pore 1334 blows out.First elevator 135 and the second elevator 136 are located at the relative two ends in 131 bottom of shell.
Glass 20 is sent to preheating device 12 by roller-way from upper sheet devices 11.Transfer roller of the glass 20 in preheating device 12
122 are driven and are heated to 550 DEG C or so.The transfer roller 122 of preheating device 12 is preferably formed by ceramic material.Glass 20 exists
550 DEG C or so this temperature also do not soften, and as transfer roller 122 is formed using ceramic material, therefore glass 20 exists
It is not in deformation when being driven by transfer roller 122.Subsequently, glass 20 is sent to glass air cushion by ceramic transfer roller 122 and adds
Thermal 13.
Refer to Fig. 2 and Fig. 3, the upper heating unit 132 of glass air cushion heater 13 may include convector 1322 and on
Heating furnace silk 1324.Convector 1322 may include high-temperature blower.Upper heating furnace silk 1324 can be located at the upper table of air supporting warm table 133
Between face 1332 and convector 1322.Multiple seal boxs 1337 are provided with air supporting warm table 133, can be set in each seal box 1337
There is lower heating furnace silk 1338.Seal box 1337 can be prepared by ceramic material, and the upper surface of seal box 1337 in the present embodiment
Constitute the part in the upper surface 1332 of air supporting warm table 133.Venthole 1334 is located on seal box 1337 and and seal box
Communicate inside 1337.134 expellant gas of blower fan are blown out from venthole 1334 after being introduced into seal box 1337 again.Also, air supporting
Multiple return-air holes 1336 can be also provided with warm table 133.Return-air hole 1336 is located between adjacent seal box 1337.Multiple return-airs
Hole 1336 is used to make the air inlet 1344 from the gas backstreaming of the blowout of venthole 1334 to blower fan 134.Venthole 1334 and return-air
Hole 1336 respectively into uniformly arranging in array-like, and can be distributed on upper surface 1332.
By the venthole 1334 gathered on blower fan 134 and air supporting warm table 133, glass 20 can be suspended in air supporting warm table
133 top, and the lower surface of glass 20 can be heated；And the upper surface of glass 20 can be carried out adding by upper heating unit 132
Heat, thus the temperature of 20 upper and lower surface of glass can kept in balance.
The fan blade of blower fan 134 is may be installed in accommodating chamber 1312, and can pass through heat-resisting axle by blower fan electricity mounted externally
Machine is driving.According to the difference of 20 thickness of glass, by adjusting the rotating speed of blower fan 134 to adjust what is gathered above seal box 1337
Venthole 1334 goes out throughput and pressure, it can be ensured that glass 20 is suspended on air supporting warm table 133.Blow from venthole 1334
The high warm air for going out returns to the air inlet of blower fan 134, and then the inner loop of achievable high-temperature hot air by return-air hole 1336, reaches
To effect of energy-conservation.To guarantee that hot inside air smoothly returns to the air inlet 1344 of blower fan 134, the gross area of return-air hole 1336 sets
It is calculated as more than five times of preferably 1334 gross area of venthole.
Fig. 4 and Fig. 5 is referred to, heating and transmission process of the glass 20 in glass air cushion heater 13 is as follows：Glass
20 are moved from import to Way out by its initial velocity for entering glass air cushion heater 13, when glass 20 move to it is close
During exit position, the second elevator 136 rises, the first elevator 135 declines (inclination angle of generation can be for 0～5 °, i.e., so that glass
Angle between 20 or upper surface 1332 and horizontal plane is changed into 0～5 °), glass 20 is under the effect of its partical gravity conducted oneself with dignity toward entering
The motion of mouth direction, as shown in Figure 4；When move to be close to entrance location when, the first elevator 135 rises, under the second elevator 136
Drop (inclination angle of generation can be 0～5 °, i.e., so that the angle between glass 20 or upper surface 1332 and horizontal plane is changed into 0～5 °),
Glass 20 is moved toward Way out by the partical gravity of its deadweight, as shown in Figure 5；When glass 20 is in glass air cushion heater
After the temperature required for tempering is heated in 13,136 adjustment position of the second elevator of glass air cushion heater 13 keep with
The import of quickly cooling device 14 is parallel, and 13 the first elevator of entrance point 135 of glass air cushion heater is raised to highest, so that it may make
Glass 20 quickly leaves glass air cushion heater 13 into quickly cooling device 14.
In quickly cooling device 14, glass 20 can be by quick air-cooled, so as to form safety glass.Final glass 20 is passed
To lower sheet devices 15, and then complete the whole toughening process of glass 20.
Above-mentioned glass tempering system of processing 10 includes glass air cushion heater 13, and glass 20 is in glass air cushion heater
During heating, glass 20 can be suspended in the top of air supporting warm table 133, by the upper surface and level that adjust air supporting warm table 133
The inclination angle in face, can utilize the deadweight of glass 20 itself and control angle of inclination to realize transmission of the glass 20 in heating process,
Allow glass 20 not deform in suspended state in tempering heating process, and be heated evenly, heat soon；And then cause life
The safety glass that output is come has the advantages that flatness is good, optical distortion few.
