The utility model also provides a glass tempering furnace, including last piece platform, heating furnace, cooling section 6 and lower piece platform, wherein the cooling section includes tempering section 61, cooling section 62, and the glass board bears the weight of by rollgang 7 and passes through in proper order last piece platform, heating furnace, cooling section 6 and lower piece platform, the glass board after the heating cools off the temperature rapidly at tempering section 61, later gets into cooling section 62 and continues the cooling, and tempering section 61 uses foretell air supply equipment to cool down the glass board rapidly and handles, and the symmetry of wind grid package 1 is arranged on rollgang 7, below, and the wind grid air outlet 12 of each wind grid package 1 is towards rollgang 7. The cooling section 62 may also use the air supply device described above to further cool the glass sheet.
In the prior art, for a device for supplying air to a cooling section of a glass tempering furnace, as shown in fig. 1, the cooling section 6 includes a tempering section 61 and a cooling section 62, and the tempering section 61 and the cooling section 62 are both composed of a plurality of air grid packs 1 and an air supply fan. The cooling section 62 is usually longer than the tempering section 61, and fans with different powers are respectively adopted for the tempering section 61 and the cooling section 62 to supply air to the air grid package 1.
For example, for thin glass with the thickness of 3mm, quenching and strengthening (toughening) are needed firstly, and then cooling with lower wind pressure is needed, wherein the process parameters are about 90-100s of heating time, 16000pa of toughening wind pressure, 5-10s of toughening time, 2000pa of subsequent cooling wind pressure and more than 20s of cooling time; for example, for thick glass with a thickness of 19mm, low wind pressure tempering is required, and then high wind pressure cooling is required, wherein the process parameters are about 900-1500s for heating time, 300pa for strengthening wind pressure and more than 300s for tempering, about 2000pa for subsequent cooling wind pressure and more than 400s for cooling. The tempering section is usually realized by pure reciprocating type (the tempering section and the cooling section share the whole air grid), through + reciprocating type (the air grid is composed of two areas, and the air supply equipment with 2 air pressures supplies air respectively, the air pressure passing through the section is high, and the air pressure of the reciprocating section is low), continuously through type (the front of the whole air grid section is a tempering area and the back is a cooling area, the two areas supply air respectively by the air supply equipment with different pressures (if a thick plate continuous furnace, the air supply equipment with the same air pressure supplies air), and the continuous conveying of the glass plate is realized in the same way.
For the part 61 of the tempering section, because the tempering section 61 needs to rapidly cool the heated glass so as to generate external stress on the surface of the glass, the requirement on quenching air pressure is very high, in the prior art, the air supply system of the strengthening section 6 adopts one or more (series) high-power or super-high-power fans to integrate air volume and then distribute air supply to the whole air grid (dozens or even dozens of independent air grid nozzles to form the whole air grid) (the fan power is concentrated at 110 KW-315 KW, and for special glass such as fireproof glass, the fan power even needs to reach more than 1000 KW); different glass thickness, required tempering section wind pressure are different, and generally glass thickness is less, and required wind pressure is higher, and fan power is big more. As shown in fig. 1, two high-power toughening fans 610 are adopted to supply air to one air collecting box 3, the power of the toughening fans 610 is more than 110kw, and the air is distributed to each air grid package 1 by the air collecting box 3. For the cooling section 62, because the air grid section for supplying air is longer, the actual length is not limited to the proportional length in the figure, and the power of the cooling fan 620 is also larger, as shown in fig. 1, two high-power cooling fans 620 are used for supplying air to one wind collecting box 3, the power of the cooling fan 620 is more than 110kw, and the wind power is distributed to each air grid package 1 by the wind collecting box 3.

However, such a wind supply system has the following drawbacks: 1. the existing fans suitable for the toughening furnace are large fans with 110 kw-315 kw and impeller diameter exceeding 1m, when the fans are used, the accelerated starting time from zero rotating speed to rated rotating speed is long, 20-50 seconds are needed each time, for thin-layer glass, the real toughening use time only needs several seconds to ten seconds (less than or equal to 20 seconds), for example, the glass with the thickness of 3mm, the heating time is 90-100 seconds, the quenching air pressure is 16000pa, the quenching time is 5-10 seconds, the subsequent cooling air pressure is 2000pa, the cooling time is 10-15 seconds, as the cooling time is far shorter than the heating time, the fans are discontinuously started and stopped when the fans are actually used, and the fans have certain standby frequency; however, the long-time preparation time of the fan is actually the idle work, the preparation time (20-50 s) of the large fan exceeds the service time (5-10 s), most of the electric energy is used for the start preparation of the fan, and great electric energy resources are wasted; 2. the heavy high-power (diameter) fan impeller has large throwing power during high-speed operation, frequent accidents of throwing and rotting of the impeller, high danger, low safety and short service life which is generally only 3-5 years; the volume is large (the diameter of the impeller reaches 1.0-1.6 meters), the occupied area is large, and once the impeller is damaged, the impeller is not easy to replace and maintain, and the impeller is inconvenient to use in practice; 3. the high-power fan, the noise is too big during the use, can reach 110 decibels, causes very big harm to operating personnel's hearing.
The utility model provides an air supply equipment mainly uses in tempering section 6, nevertheless can be applicable to cooling zone 7 equally, can be suitable for whole cooling section, selects the small-size air feeder 21 of different power, model and quantity can.
The air supply equipment can be applied to the production and the manufacture of flat glass and bent glass.
By adopting the technical scheme of the utility model, a method of replacing one large fan by a plurality of low-power high-pressure fans/air pumps is adopted, so that a plurality of low-power high-pressure fans/air pumps supply air to the cooling air grid section; the blower/air pump is small in noise and low in noise, so that acoustic pollution is reduced, and safety is greatly improved; and the individual is easy to maintain and replace when damaged, the service life of the whole is longer, the practical application is more portable, and because the air supply device group units are controlled by independent switches and the independent air pressure is adjusted, when the glass plate moves forwards, the air supply device group unit in the rear area through which the glass plate passes can be shut down in advance, thus avoiding unnecessary electric energy consumption and having obvious energy-saving effect.
