Abstract
The utility model relates to a LOW-E (low emissivity) glass tempering furnace. The LOW-E glass tempering furnace comprises a glass tempering furnace, wherein a base plate of a heating air box in the glass tempering furnace is a stainless steel air outlet plate; the stainless steel air outlet plate is provided with air outlets; a stainless steel filter plate is arranged below a ceramic roller table; a lower electric heating component is arranged below the stainless steel filter plate. The LOW-E glass tempering furnace has the advantages that the radiation wavelength of the heater is concentrated in the absorption range of glass and the infrared rays radiated from the heating component are filtered while the glass heating speed is increased, so that the short infrared waves are filtered out but the infrared light with wavelength being 3-8 microns can smoothly penetrate through the surface of a LOW-E film and then achieve efficient heating on the glass body; a convection furnace is not provided with heating components inside and all the heating components are installed inside a convection air box in the furnace; only convection tuyeres made of stainless steel face the glass and play a role in convection heating and in radiating middle-infrared waves while filtering near-infrared waves.
Description
Technical field
When the utility model relates to a kind of LOW-E glass tempering tempering, can fundamentally eliminate the LOW-E glass tempering furnace that the short infrared ray ripple burns out LOW-E film on the LOW-E glass surface, belong to glass tempering furnace and manufacture field.
Background technology
When at present glass tempering furnace was to the LOW-E glass tempering, when furnace temperature reaches 680 while spending, the surface temperature of nichrome wire can surpass 800 degree.In the radiating capacity that now nichrome wire is launched, approximately have more than 50% and 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, to the receptivity extra-heavy of wavelength at the ir radiation of 1 micron, the surface that these heat energy act on rete makes the rete local location overheated, cause as rete burn out, the series of problems of buckling deformation, bottom scratch etc.
The utility model content
Purpose of design: avoid the weak point in background technology, while designing a kind of LOW-E glass tempering tempering, can fundamentally eliminate the LOW-E glass tempering furnace that the short infrared ray ripple burns out LOW-E film on the LOW-E glass surface.
Design: in order to realize above-mentioned purpose of design.1, the Heating air box base plate is on stainless steel plate exhausting plate and stainless steel plate exhausting plate, to have the design of air outlet, is one of technical characterictic of the present utility model.The purpose of doing like this is: in test and practice, find that in stove temperature reaches 500 degree when above, the capability of resistance to radiation of LOW-E film lost efficacy substantially, but the LOW-E film is to the receptivity extra-heavy of wavelength at the ir radiation (short infrared ray ripple) of 1 micron, if there is high temperature part, to be directed at rete will be burned, and the glass under rete is just better in the absorption of the infrared energy of 3 ~ 8 microns to wavelength.The application in design for this reason, the radiation wavelength of well heater is concentrated in the scope of glass absorption, when improving glass heats speed, reduce the heats to rete, guarantee that rete can remain on a relatively low temperature levels when glass reaches the tempering temperature.The utility model is on structure design for this reason, adopt stainless steel plate as the Heating air box exhausting plate, because stainless steel plate can filter near infrared ray ripple (short infrared ray ripple) effectively, be that it can filter the infrared rays that Heating element gives off, 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: a kind of LOW-E glass tempering furnace, comprise glass tempering furnace, in described glass tempering furnace, the Heating air box base plate is the stainless steel plate exhausting plate, has air outlet on the stainless steel plate exhausting plate, the ceramic roller below is provided with the stainless steel screen plate, and stainless steel screen plate below is lower an electric heating element.
The utility model is compared with background technology, the one, the radiation wavelength of well heater is concentrated in the scope of glass absorption, when improving glass heats speed, the infrared rays namely Heating element 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 all are installed in the convection current bellows inside in stove; The 3rd, towards the convection current tuyere that only having of glass utilizes stainless steel to make, it has played convective heating and has filtered the effect of infrared wave in the radiation simultaneously of near infrared ripple.
The accompanying drawing explanation
Fig. 1 is the local structure schematic diagram of LOW-E glass tempering furnace.
Embodiment
Embodiment 1: with reference to accompanying drawing 1.A kind of LOW-E glass tempering furnace, comprise glass tempering furnace, in described glass tempering furnace, Heating air box 1 base plate is stainless steel plate exhausting plate 2, on stainless steel plate exhausting plate 2, has air outlet 3, ceramic roller 6 belows are provided with stainless steel screen plate 7, and stainless steel screen plate 7 belows are lower an electric heating element 8.Stainless steel plate exhausting plate 2 is furnished with many group V font stainless steel plate wind guide tanks 3, and air outlet 4 is positioned on V font stainless steel plate wind guide tank 3 inclined-planes, both sides.Special-purpose Heating air box heating means of its LOW-E glass tempering: be positioned at infrared wave that an electric heating element 4 of heating container sends and comprise wavelength and be less than 3 microns infrared waves and wavelength at 3～8 microns infrared waves, when wavelength be less than 3 microns infrared waves and wavelength at 3～8 microns infrared waves by the many groups V font stainless steel plate wind guide tank 3 in heating container 1 bottom stainless steel plate exhausting plate 2, during by air outlet opening 4 ejection, 3～8 microns infrared waves are heated the stainless steel plate exhausting plate 2 of bellows 1 bottom, stainless steel plate wind guide tank 3 is crossed filtering, the heats of reduction to rete, guarantee that rete can remain on a relatively low temperature levels when glass reaches the tempering temperature, and the infrared wave of 3～8 micron wave lengths carries out high-efficiency heating to glass body after penetrating the LOW-E film surface on the LOW-E glass surface.In like manner, be positioned at the short infrared ray ripple that toughened glass below (ceramic roller 6 belows) lower an electric heating element 8 of stainless steel screen plate 7 belows produces the same by the method for filtering.
Embodiment 2: on the basis of embodiment 1, on stainless steel screen plate 7, have a plurality of air outlets.
What need to understand is: although above-described embodiment is to the mentality of designing of the present utility model detailed text description of contrasting; but these text descriptions; just the simple text of the utility model mentality of designing is described; rather than to the restriction of the utility model mentality of designing; any combination, increase or modification that does not exceed the utility model mentality of designing, all fall in protection domain of the present utility model.
