Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
In conjunction with as depicted in figs. 1 and 2, frit smelting furnace, comprising smelting furnace body of heater 1 and radiant heating device, be provided with vertical hearth of melting furnace 2 in described smelting furnace body of heater 1, the opening of described hearth of melting furnace 2 upper/lower terminal is respectively dog-house 21 and glass metal outlet 22. In order to avoid frit to contact with easy coloring material (iron, nickel, tin, platinum, palladium, rhodium etc.), effectively suppress glass coloring, improve the transmitance of glasswork particularly high-refractivity lanthanide glass, this frit smelting furnace is generally made up of high temperature resistant ceramic, selects Fe as far as possible2O3Content is less or does not contain Fe2O3Material, it is preferred to use refractoriness is the ceramic of more than 1200��1450 DEG C, such as: SiO2. Wherein, smelting furnace body of heater 1 can be prism-shaped or cylinder shape, it is preferable to quadrangular shape or cylinder shape; The furnace wall thickness of smelting furnace body of heater 1 is generally 20��80mm, it is preferable to 25��30mm. Radiant heating device can be arranged in hearth of melting furnace 2, it is also possible to setting corresponding with smelting furnace body of heater 1, as long as can be heated by hearth of melting furnace 2; Radiant heating device is preferably far-infrared heating tube. From the frit free-falling under gravity that dog-house 21 adds, and through radiant heating device heat fused, the glass metal of last melting exports 22 outflows from glass metal.
In order to improve the residence time of frit in hearth of melting furnace 2, shorten the length of smelting furnace body of heater 1, described hearth of melting furnace 2 is provided with raw material retention structure. Concrete, more as depicted in figs. 1 and 2, described raw material retention structure comprised material screen 31 and was positioned at the resistance material baffle plate 32 on the downside of material screen 31. The bottom crossing material screen 31 is provided with at least one material path 311, and the frit of preliminary melting can flow through from material path 311, continues to fall. Resistance material baffle plate 32 can block glass metal further, is beneficial to the abundant melted by heat of frit, reduces technological temperature, and reduces the speed that glass flows out.
Preferably, more as shown in Figure 2, described resistance material baffle plate 32 is at least two pieces, and is divided into two corresponding column distributions along the height direction of hearth of melting furnace 2, and two row resistance material baffle plates 32 are crisscross arranged.
