Description
Technical field
The present invention relates to glass production field, a kind of melting furnaces flow control methods for reinforcing fiber glass are specifically referred to.
Background technology
Tank block is the position for being washed away most serious in whole glass furnace by high-temperature glass liquid in glass furnace,Refractory material as glass furnace tank block all has the characteristic that high temperature resistance corrodes and anti-glass metal washes away,But in actually used,Such refractory material can only play the use time of extension glass furnace pool wall,Tank block still can wash away erosion by high-temperature glass liquid,It is more infusibilized due to tank block refractory material relatively-high temperature glass metal,So being etched the refractory material of high-temperature glass liquid or being present in glass metal with refractory material little particle or with the glassy form of fritting,Eventually cause the plethora and strip flaw of finished product,Largely effect on glass quality,E-glass particularly harsh to quality requirement,Its influence becomes apparent from,So reducing influence of the tank block refractory material to glass metal quality,The high quality glass problem that particularly display base plate glass furnace is paid close attention to is produced very much always.
In addition, in production E-glass（Such as PDP glass, panel glass, liquid-crystalline glasses etc. are touched）When,Because the thickness of glass all includes from 0.1mm to 3.0mm,And thinner strength of glass is lower,The pull speed of glass plate also preferably must be held in relatively small scope,To ensure that glass plate is thin,Require that pull speed can not be fast again,Thus the actual pull amount of limitation glass must be corresponding with the thickness of the glass of production,Thinner glass,Its pull amount is also small,The objective fluctuation for also causing glass pull amount needs in actual production larger,And the fusing amount that the larger fluctuation of glass pull amount certainly will be also required to melting furnaces glass metal also has and significantly adjusts,But the fluctuation of fusing amount can cause the disorder of melting furnaces,While adjusting pull amount under normal circumstances,Also fusing amount progressively can slowly be reduced,The influence to melting furnaces stability is controlled in acceptable scope as far as possible in this way,But this mode certainly will cause the time interval between two kinds of variety productions long,The total output of product is caused to reduce,Even if simultaneously slow reduce fusing amount,Also influence of the fluctuation of fusing amount to melting furnaces stability cannot completely be avoided.
The content of the invention
It is an object of the invention to provide a kind of melting furnaces flow control methods for reinforcing fiber glass, by the spillway discharge of accurate regulation glass metal, it is convenient to be excluded containing the glass metal for being washed the pool wall refractory material impurity for corroding peeling, and then ensure requirement of the various thickness glass productions to pull amount.
The purpose of the present invention is achieved through the following technical solutions：
A kind of melting furnaces flow control methods for reinforcing fiber glass, including overflow launder brick, adjusting brick and guiding brick, the overflow launder brick is arranged on the junction of pool wall after melting furnaces melting end both sides tank block and melting end, overflow launder brick is connected with brick is oriented to, adjusting brick is rotatably arranged on overflow launder brick and is oriented to the junction of brick, is oriented on the side of brick and is provided with temperature control rifle, and groove is provided with the guiding brick, groove bottom land is provided with spout hole, and discharge structure is provided with immediately below the spout hole.The present invention is operationally, unnecessary glass metal can be under the rotation of adjusting brick regulation in melting furnaces, flow through and be oriented to brick again by the spout hole outflow of guiding brick bottom, the pool wall refractory material impurity and glass metal cooling collection for corroding and peeling off will be washed under the cooling condition of discharge structure, it is free to rotate installed in the temperature control rifle being oriented on brick side, by the way of combustion gas and air pre-mixing are burnt again, and adjusted with the elevational change of metal level in melting furnaces, the consumption of the mobility status regulating gas according to the glass metal for overflowing, glass metal stream stabilization is maintained in suitable viscosity, ensure the stability of overflow glass flow quantity；The need for the present invention can change pull amount is ensured in the case of not changing fusing amount, disclosure satisfy that the production of thickness ㎜ glass substrates from 0.3 ㎜ to 3.0, according to fusing amount=pull amount+spillway discharge, i.e. in the case where fusing amount keeps constant, pull amount is changed by accurate adjustment, it is to avoid cause product quality to be affected because of the fluctuation of melting furnaces fusing amount.
The discharge structure includes water quenching pipe, guide pipe and collects dolly, and the water quenching pipe is obliquely installed and is connected between spout hole and guide pipe, and guide pipe is connected with dolly is collected.Cooled down in water quenching pipe by the glass metal of spout hole, then collection dolly is caused by guide pipe, finally the glass chip by glass metal cooling generation under the focusing on for collecting dolly is recycled, and reduces the cost of glass production.
The water quenching pipe includes spray thrower, inner layer sleeve and outer layer sleeve, cooling chamber is provided between inner layer sleeve and outer layer sleeve, spray thrower is arranged in inner layer sleeve, two water inlet As are arranged at intervals with the side of kiln in outer layer sleeve, water inlet B is provided with the opposite side of outer layer sleeve, water inlet A, water inlet B are connected with spray thrower.The glass metal for overflowing is cooled down in water quenching pipe, two kinds of water quenching methods can be used, when sprinkling water quenching method is carried out to overflow glass metal, water with pressure is flowed into by the water inlet B of spray thrower, sprayed by bar shaped mouth spray, form several layers of water curtain and be sprayed at the enterprising water-filling of glass metal and quench glass, while effectively being cooled down to inner layer glass；When water logging water quenching method is carried out to overflow glass metal, in the cooling chamber that water with pressure is entered between inner layer sleeve and outer layer sleeve by two outer layer sleeves near spaced water inlet A on the side of kiln, first inner layer sleeve is cooled down, then flowed out from inner layer sleeve and outer layer sleeve upper opening, left from inner layer sleeve inner side again, and start water quenching glass.
The guide pipe includes special-shaped tube seat and support base, and support base is connected by supporting plate with the middle part of special-shaped tube seat, and the notch of special-shaped tube seat is connected with dolly is collected.After forming glass chip after water quenching pipe cools down glass metal, the cooling water of mixing flows through special-shaped tube seat together with chip, is finally collected dolly and focuses on.
The spray thrower includes multiple spaced bar shaped mouth sprays, and spacing between two adjacent bar shaped mouth sprays is L, and 50 ㎜≤L≤100 ㎜.The spacing of the adjacent two bar shaped spray head on spray thrower is arranged on 50 ㎜≤L≤100 ㎜ so that the several layers of water curtain that water quenching pipe is formed when carrying out and spraying water quenching method cooling are more uniform, it is ensured that the good cooling effect of glass metal.
The present invention compared with prior art, has the following advantages and advantages：
