Abstract
The present invention relates to a kind of device of forced convection heating of glass, especially to the device that the forced convection of low radiation coated glass is heated.The present invention is in order to overcome current domestic prior art: fire box temperature control accuracy is poor, although heat transfer efficiency is low can tempered and low-radiation coated glass, but the production capacity of equipment is low, the defects such as the poor quality of product, invent that a kind of fire box temperature control accuracy is high, heat transfer efficiency is high and the low radiation coated glass forced convection heating unit of homogeneous heating.The present invention sets up one section of independent convection current air channel, and be provided with equally distributed well heater thereon, the hot blast of high-temperature blower blowout is after the circulation of convection current air channel, make temperature more easy to control, equally distributed well heater, uniformly heat can be calorified the surface of glass to be processed, significantly improve the usefulness of heating tempering and the quality of the rear glass surface of processing.
Description
Technical field
The present invention relates to a kind of device of forced convection heating of glass, especially to the device that the forced convection of low radiation coated glass is heated.
Background technology
At present, the energy-conservation large bottleneck being China and realizing sustainable development target, China is construction industry big country, and building energy consumption accounts for more than 1/3rd of national total energy consumption.
Low radiation coated glass, having excellent heat insulation, heat-insulating property, is one of indispensable main raw in building energy conservation.
Because the requirement of security (standard forced by national security glass), low radiation coated glass has to pass through tempering process.
But due to the reflectivity feature that low radiation coated glass face is high, with common radiating heat system, its source of radiation very must press close to glass, so just have the edge of a large amount of heat radiations to glass, cause glass edge, angle part overheated, cause instability and on face, occur picture frame effect, namely commonly occur coloured stress pattern in corner.Traditional radiation furnace tempered and low-radiation coated glass is adopted to can not meet requirement.
Putting before this, in order to overcome its radiation-resistant characteristic of low radiation coated glass, all studying based on the toughened glass equipment of convective heating technology both at home and abroad.
At present, domestic forced convection heating unit, mainly adopt and heat in two ways: a kind of is heater profile at the blast inlet of high-temperature blower or air outlet (see Fig. 2), and such result is that in burner hearth, heating curve is destroyed, heating is uneven, temperature control precision is poor.Another kind is the turnover air channel (see Fig. 3) not having independently high-temperature blower, and the result caused is that the efficiency of heating is lower.
In view of the low emissivity glass forced convection heating unit of current domestic prior art, its temperature control precision is poor, and heat transfer efficiency is low.Although can tempering Low-e glass, the production capacity of equipment is low, the poor quality of product.Even, after tempering, considerably reduce 3 resistivity of rete, thus greatly reduce the energy-saving index of low emissivity glass.
Therefore, overcome above-mentioned defect, inventing a kind of being applicable to and the annealing furnace of energy highly-efficient processing low radiation coated glass, is that pendulum is badly in need of and difficult task in face of all annealing furnace manufacturerss.
Summary of the invention
The present invention is in order to overcome the following defect of the low radiation coated glass forced convection heating unit of current domestic prior art: fire box temperature control accuracy is poor, and heat transfer efficiency is low.Although can tempered and low-radiation coated glass, the production capacity of equipment be low, the poor quality of product.Even, after tempering, considerably reduce 3 resistivity of rete, thus greatly reduce the energy-saving index of low emissivity glass.
Thus, invent that a kind of fire box temperature control accuracy is high, heat transfer efficiency is high and the low emissivity glass forced convection heating unit of homogeneous heating.
Low radiation coated glass forced convection heating unit of the present invention, comprises roller-way, the forced convection mechanism or be mounted on the upside of roller-way and is mounted on the larger forced convection mechanism and of power on the upside of roller-way and is mounted on the less forced convection mechanism for maintaining roller channel temp of power on the downside of roller-way.Described Mei Zu forced convection mechanism, is made up of multiple convector.Described forced convection device is made up of a high-temperature blower with two air outlets in left and right, closed and two air outlets in two ends and high-temperature blower are connected a convection current air channel, described convection current air channel comprises a heating zone, described heating zone to be located at above roller-way and parallel with roller-way, and heating zone is provided with that spacing uniformly more organizes well heater.
The beneficial effect that the present invention produces is: be provided with closed convection current air channel and equally distributed well heater, not only avoided heat loss but also make hot blast through circulation post-heating evenly, thus both made in-furnace temperature more easy to control, and improve the quality of production capacity and product.

Fig. 2 is the structural representation of prior art 1;
Fig. 3 is the structural representation of prior art 2.
Embodiment
As shown in Figure 1, the present invention is a kind of low radiation coated glass forced convection heating unit, comprise roller-way and two groups of forced convection mechanisms compositions being mirror image and being distributed in the upper and lower both sides of roller-way, the forced convection mechanism power be wherein positioned at above roller-way is comparatively large, and for heating the main heating source of toughened glass, the forced convection mechanism power be positioned at below roller-way is less, act as heated table, to keep roller-way in transmission, temperature equalisation, thus improve the heating usefulness of tempering and the quality of product.Mei Zu forced convection mechanism, is connected to form by multiple convector 1, and each convector 1 is made up of a high-temperature blower 11 and a convection current air channel 12, and the both sides of high-temperature blower 11 are provided with two air outlets 13, and is connected with stream two ends, air channel 12.When high-temperature blower 11 works, will form the thermal cycling closed in convection current air channel 12, closed environment avoids thermosteresis, and makes the even heat in each section of convection current air channel 12 by thermal cycling.Convection current air channel 12 hypomere is heating zone 14, near roller-way 1 and parallel with it, heating zone 14 is provided with spacing many group well heaters 15 uniformly, to reach object even heat being delivered to glass to be processed, the glass surface quality of tempering is higher, and improves the usefulness of tempering.
Specific embodiment described herein is only to the explanation for example of the present invention's spirit.Those skilled in the art can make various amendment or supplement or adopt similar mode to substitute to described specific embodiment, but can not depart from spirit of the present invention or surmount the scope that appended claims defines.
