Abstract

The utility model relates to a forced convection heating device for glass, in particular to a forced convection heating device for low emissivity coated glass. The utility model aims to overcome the defects that the furnace box temperature control precision is low, the heat transfer efficiency is low, although the low emissivity coated glass can be toughened, the productivity of equipment is low, the quality of products is low and the like in the prior art in China, and discloses a forced convection heating device for low emissivity coated glass, which has the advantages of high furnace box temperature control precision, high heat transfer efficiency and uniform heating. A section of independent convection airduct is arranged, and is provided uniformly distributed heaters; after hot air blown by a high temperature fan is circulated by the convection airduct, the temperature is easy to control; and the uniformly distributed heaters can uniformly heat the surface of the glass to be processed, and the heating and toughening efficiency and the quality of the surface of the processed glass are greatly improved.

Description

The forced convection heating unit of low radiation coated glass
Technical field
The utility model relates to a kind of device of forced convection heating of glass, the device that especially forced convection of low radiation coated glass is heated.
Background technology
At present, energy-conservation is the big bottleneck that China realizes sustainable development target, and 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 has excellent heat insulation, heat-insulating property, is one of indispensable main raw in the building energy conservation.
Because the requirement of security (national security glass is forced standard), low radiation coated glass must pass through tempering and handle.
But because the high reflectivity characteristics of low radiation coated glass face; With common radiation heating system; Its source of radiation must be pressed close to glass very much, so just has the limit portion that great amount of heat is radiated glass, causes the overheated of glass edge, angle part; Cause instability and the picture frame effect on face, occurs, promptly common to coloured stress pattern occurs in corners.Adopt traditional radiation furnace tempered and low-radiation coated glass to satisfy not requirement.
Putting before this, in order to overcome its radiation-resistant characteristic of low radiation coated glass, is master's toughened glass equipment in research with the convective heating technology all both at home and abroad.
At present; Domestic forced convection heating unit; Main adopt the dual mode heating: a kind of blast inlet or air outlet (referring to Fig. 2) that is heater profile at high-temperature blower, such result is that burner hearth internal heating curve is destroyed, heats inequality, temperature control precision is poor.Another kind is not have the independently turnover air channel (referring to Fig. 3) of high-temperature blower, and the result who causes is that the efficient of heating is lower.
In view of the low emissivity glass forced convection heating unit of present domestic prior art, its temperature control precision is poor, and heat transfer efficiency is low.Though can tempering Low-e glass,, the production capacity of equipment is low, the poor quality of product.Even, reduce by 3 resistivity of rete later on significantly through tempering, thereby reduced the energy-saving index of low emissivity glass greatly.
Therefore, overcome above-mentioned defective, invent a kind ofly be fit to, and annealing furnace that can the highly-efficient processing low radiation coated glass, be that pendulum is badly in need of and difficult task in face of all annealing furnace manufacturerss.
The utility model content
The utility model is for the following defective of the low radiation coated glass forced convection heating unit that overcomes present domestic prior art: the fire box temperature control accuracy is poor, and heat transfer efficiency is low.Though can tempered and low-radiation coated glass, the production capacity of equipment is low, the poor quality of product.Even, reduce by 3 resistivity of rete later on significantly through tempering, thereby reduced the energy-saving index of low emissivity glass greatly.
Thereby, 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.
The described low radiation coated glass forced convection of the utility model heating unit comprises that forced convection mechanism or that roller-way, is mounted on the roller-way upside is mounted on the bigger forced convection mechanism and of roller-way upside power and is mounted on the less forced convection mechanism that is used to keep the roller-way temperature of roller-way downside power.Said every group of forced convection mechanism is made up of a plurality of convectors.The high-temperature blower of two air outlets, a sealing and convection current air channel that two air outlets in two ends and high-temperature blower link to each other was formed about described forced convection device had by one; Said convection current air channel comprises a heating zone; Said heating zone is located at roller-way top and parallel with roller-way, and heating zone is provided with the many uniformly group well heaters of spacing.
The beneficial effect that the utility model produced is: the convection current air channel and the equally distributed well heater that are provided with sealing; Not only avoided the loss of heat but also make hot blast more even through the circulation post-heating; Thereby both made that the interior temperature of stove was more easy to control, and improved 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 utility model is a kind of low radiation coated glass forced convection heating unit, comprise roller-way and two groups be mirror image be distributed in roller-way up and down the forced convection mechanism of both sides form; The forced convection mechanism power that wherein is positioned on the roller-way is bigger, is the main thermal source of heating toughened glass, and the forced convection mechanism power that is positioned at the roller-way below is less; Act as the heating roller-way; Keeping roller-way in transmission, temperature equalisation, thus improve the usefulness of heating tempering and the quality of product.Every group of forced convection mechanism is connected to form by a plurality of convectors 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 12 two ends, air channel.During high-temperature blower 11 work, will form the thermal cycling of sealing in the convection current air channel 12, the environment of sealing has been avoided thermosteresis, and makes the heat of convection current air channel 12 each sections even through thermal cycling.Convection current air channel 12 hypomeres are heating zone 14; Near roller-way 1 and parallel with it, heating zone 14 is provided with the many uniformly group well heaters 15 of spacing, to reach the purpose that heat evenly is delivered to glass to be processed; The glass surface quality of tempering is higher, and has improved the usefulness of tempering.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can not depart from the spirit of the utility model or surmount the defined scope of appended claims.
