Abstract
The invention relates to a heating bellow specially used for LOW-E glass toughening and an LOW-E glass toughening furnace which fundamentally eliminate LOW-E film burned-out on LOW-E glass surfaces by short infrared waves during LOW-E glass toughening. The bottom plate of the heating bellow is a stainless steel plate wind-outlet plate provided with wind outlets. The heating bellow and the toughening furnace are advantageous in that: (1) the radiation wavelength of a heater is centralized in a range capable of glass absorption, infrared rays radiated by heating elements are filtered at the same time of increasing the glass heating speed, and therefore short infrared waves are filtered, and infrared light having a wavelength of 3-8 [mu]m successfully penetrates the surface of an LOW-E film so as to achieve efficient heating for a glass main body; (2) a convection furnace (the glass toughening furnace) is free of heating elements, and all the heating elements are installed in a convection bellow in the furnace; and (3) only convection wind nozzles made of stainless steel face towards the glass and the wind nozzles have functions of convection heating, near-infrared wave filtration, and radiation of intermediate infrared waves.
Description
Technical field
While the present invention relates to a kind of LOW-E glass tempering tempering, can fundamentally eliminate the special Heating air box of LOW-E glass tempering and LOW-E glass tempering furnace that short infrared ray ripple burns out LOW-E film in LOW-E glass surface, belong to glass tempering furnace Heating air box and heating means and manufacture field.
Background technology
When at present glass tempering furnace is to LOW-E glass tempering, when furnace temperature reaches 680 while spending, the surface temperature of nichrome wire can exceed 800 degree.In the radiating capacity that now nichrome wire is launched, approximately have and more than 50% belong to wavelength at the near infrared ray ripple (short infrared ray ripple) of 1 micron, and LOW-E glass is at 500 degree when above, the capability of resistance to radiation of its LOW-E film lost efficacy substantially, receptivity extra-heavy to wavelength at the ir radiation of 1 micron, the surface that these heat energy act on rete makes rete local location overheated, causes as rete burns out, the series of problems of buckling deformation, bottom scratch etc.
Summary of the invention
Purpose of design: avoid the weak point in background technology, while designing a kind of LOW-E glass tempering tempering, can fundamentally eliminate the special Heating air box of LOW-E glass tempering and LOW-E glass tempering furnace that short infrared ray ripple burns out LOW-E film in LOW-E glass surface.
Design: in order to realize above-mentioned purpose of design.1, Heating air box base plate is the design that has air outlet on stainless steel plate exhausting plate and stainless steel plate exhausting plate, is one of technical characterictic of the present invention.The object of doing is like this: in test and practice, find that temperature reaches 500 degree when above in stove, the capability of resistance to radiation of LOW-E film lost efficacy substantially, but LOW-E film is the receptivity extra-heavy at the ir radiation (short infrared ray ripple) of 1 micron to wavelength, if there is high temperature part, to be directed at rete will be burned, and glass under rete to wavelength in the absorption of the infrared energy of 3 ~ 8 microns just better.The application in design for this reason, the radiation wavelength of well heater is concentrated in the scope of glass absorption, in improving glass heats speed, reduce the heats to rete, guarantee that rete can remain on a relatively low temperature levels in the time that glass reaches tempering temperature.The present invention is in structure design for this reason, adopt stainless steel plate as Heating air box exhausting plate, because stainless steel plate can filter near infrared ray ripple (short infrared ray ripple) effectively, be that the infrared rays that it can give off Heating element filters, make short infrared wave by filtering, realize afterwards the high-efficiency heating to glass body thereby the infrared luminous energy of guaranteeing 3 ~ 8 micron wave lengths penetrates LOW-E film surface smoothly.
Technical scheme 1: the special Heating air box of a kind of LOW-E glass tempering, Heating air box base plate is stainless steel plate exhausting plate, has air outlet on stainless steel plate exhausting plate.
Technical scheme 2: a kind of LOW-E glass tempering furnace, comprise glass tempering furnace, in described glass tempering furnace, Heating air box base plate is stainless steel plate exhausting plate, on stainless steel plate exhausting plate, has air outlet, ceramic roller below is provided with stainless steel screen plate, and stainless steel screen plate below is lower an electric heating element.
Technical scheme 3: the special Heating air box heating means of a kind of LOW-E glass tempering, be positioned at the infrared wave that an electric heating element of heating container sends and comprise short infrared ray ripple and middle infrared (Mid-IR) ripple, when short infrared ray ripple and middle infrared (Mid-IR) ripple are by the many groups V font stainless steel plate wind guide tank in the stainless steel plate exhausting plate of heating container bottom, while ejection by air outlet opening, the stainless steel plate exhausting plate of the heated bellows of middle infrared (Mid-IR) ripple bottom, stainless steel plate wind guide tank is crossed filtering, reduce the heats to rete, guarantee that rete can remain on a relatively low temperature levels in the time that glass reaches tempering temperature, and middle infrared (Mid-IR) ripple carries out high-efficiency heating to glass body after penetrating the LOW-E film surface in LOW-E glass surface.
The present invention is compared with background technology, the one, the radiation wavelength of well heater is concentrated in the scope of glass absorption, in improving glass heats speed, infrared rays Heating element being given off filters, make short infrared wave by filtering, realize afterwards the high-efficiency heating to glass body and the infrared luminous energy of 3～8 micron wave lengths penetrates LOW-E film surface smoothly; The 2nd, in convection furnace (glass tempering furnace), there is no heating unit, all heating original papers are all installed in the convection current bellows inside in stove; The 3rd, the convection current tuyere that utilizes stainless steel to make towards only having of glass, it has played convective heating and has filtered the effect of infrared wave in the radiation simultaneously of near infrared ripple.
