Abstract
The utility model discloses a device for reducing volatile matter calculus in vent holes of a platinum channel. The device comprises a mullite brick body and a heating element arranged at the bottom of the device; and a wedge-shaped groove is arranged at the upper part of the mullite brick body; and one end of the wedge-shaped groove is wide and deep, and the other end of the wedge-shaped groove is shallow and wide. The device has the beneficial effects that gaseous volatile matters are not easy to condense, solids are not easy to separate out, and even though few precipitates occur, the precipitates flow out along the slope of the wedge-shaped groove and do not drop into molten glass.
Description
Technical field
The utility model relates to a kind of device that prevents condensation, particularly a kind of device that is used to reduce platinum channel venting hole volatile matter calculus.
Background technology
In the procedure for producing of high quality glass such as opticglass, liquid crystal substrate glass; All be unable to do without platinum channel; Adjusting section (or homogenizing zone) at platinum channel generally all is provided with venting hole; Be used for regulating the redox condition of glass metal, make the defective such as bubble, platinum calculus of glass be reduced to certain level.Very high because of regulating section (or homogenizing zone) temperature requirement; A lot of materials in the glass metal such as highly volatiles such as boron oxide, White tin oxide, condensation are separated out in the lower venting hole mouth of pipe position of temperature; During the non-alkali glass that particularly adopts White tin oxide to make finings is produced; Because the saturated vapor pressure of White tin oxide more than 1500 degree is higher; The White tin oxide of very small amount is volatilizable in the glass metal separates out in mouth of pipe equitemperature lower, and condensation forms and can't be absorbed by glass after the White tin oxide crystallisate is fallen in the glass again, will in final glass, produce a lot of calculus.
The utility model content
The goal of the invention of the utility model is: the problem to above-mentioned existence, a kind of device that is used to reduce platinum channel venting hole volatile matter calculus is provided, and can reduce the quantity of stannide calculus greatly.
The technical scheme that the utility model adopts is such: a kind of device that is used to reduce platinum channel venting hole volatile matter calculus; The heating member that comprises mullite brick body and bottom thereof; Said mullite brick body top is provided with a webge slot, and an end of this webge slot is wide and dark, and the other end is shallow and narrow.
As optimal way, said mullite brick body is inverted on the arrangement plate of a band platinum pipe, and this platinum pipe stretches into the wedge shape groove width and a dark end.
As optimal way, said heating member is provided with heater.
As optimal way, said heater is nickel chromium triangle heater strip or globars.
As optimal way, said mullite brick body and heating member outside surface are provided with thermal insulation layer.
In sum, owing to adopted technique scheme, the beneficial effect of the utility model is: the gaseous state volatile matter is not easy in webge slot condensation and separates out solid, even there is a spot of precipitate also can to flow out along the gradient of webge slot, can not fall back in the glass metal.
