Description
Technical field
The present invention relates to a kind of glass production fields, and in particular to a kind of bottom of pond structure for producing ultra-clear glasses.
Background technique
Ultra-clear glasses are a kind of super transparent low iron glasses, it is a kind of high-quality, multifunctional novel high-grade glass kind,
Light transmittance is up to 91.5% or more, and ultra-clear glasses are in normal production, and there are the glass metals that two strands of loop directions are opposite in melting furnaces
Stream, one is the liquid streams that feeds intake before hot spot, and one is the molding liquid stream after hot spot, glass liquid stream is in cyclic process integrally to out
Card neck is mobile at material mouth, and existing ultra-clear glasses melting furnaces mostly use flat or bottom of pond structure with tilt stage, though such structure
So simple, convenient for construction, but rear portion pond is deeper, and glass flow layer thickness is thicker, and the clarification for being unfavorable for microbubble sheds, hot spot temperature
Degree is higher, is affected by reflux at clarification, glass metal quality can be caused to fluctuate widely when extraction has large change.
Summary of the invention
In order to overcome the shortcomings of the prior art among the above, the present invention uses a kind of discharge that can speed up microbubble,
Reduce hot(test)-spot temperature, have accelerate clarification, stop clarification and homogenization after glass metal reflux, stabilized glass liquid stream the characteristics of one
Kind produces the bottom of pond structure of ultra-clear glasses.
The purpose of the present invention is what is realized by following scheme: a kind of bottom of pond structure producing ultra-clear glasses, comprising: feed intake
At mouthful, at clarification, it is characterized in that being: successively increasing equipped with first step, second step, the on the right at the feeding port
Three steps, the 4th step, the right side of the 4th step are equipped with weir, are at reflux on the right of the weir.
Preferably, the second step middle position is equipped with bubbling device, and the bubbling device is in long strip, above
Longitudinal direction is furnished with multiple circular holes.
Preferably, depth is 1.5m at the feeding port.
Preferably, the first step, second step, third step, the 4th step each layer height be set as 0.1-
0.2m。
Preferably, depth is 0.7-1.1m at the clarification.
Preferably, the weir height is 0.5-0.75m.
A kind of bottom of pond structure producing ultra-clear glasses of the invention, it has the advantage that:
(1) glass metal homogenizing can be effectively improved and clarifying effect, the convection current situation of stabilized glass liquid improve glass product
Quality；
(2) fusion temperature is reduced, melting furnaces energy consumption is reduced, can realize higher melting rate in lesser kiln size,
Save the investment of melting furnaces；
(3) it reduces the stagnant area of glass metal and stops unhelpful reflux, keep the flow velocity and fluid layer thickness that liquid stream is stable in melting furnaces
Degree keeps refining quality unaffected when substantially going up and down extraction.
Specifically, 1, it is deep to different pond is arranged between clarification at dispensing port: ultra-clear glasses fusion temperature is high, glass
Transmitance is high, and the upper and lower level temperature difference is small, and bottom of pond temperature is higher, larger to the erosion of bottom of pond refractory material, therefore ultra-clear glasses pond deep one
As more common float glass pond it is deeper, deeper settling section is unfavorable for the discharge of microbubble in glass, in response to this problem, along glass
Different ponds depths are arranged according to different zones in glass flow direction, set 1.5m or so deeply for pond at feeding port before hot spot, lead to after hot spot
It crosses setting bottom of pond step and pond is lifted to 1m or so deeply in settling section, step is arranged 4 or so, and every step raises 100 ~
200mm or so, entire bottom of pond is left deep right shallow, and the deeper bottom of pond of left part extends batch in the residence time of height temperate zone, guarantees glass
The convection current of glass liquid is conducive to the fusing of batch, is conducive to improve melting rate, right part settling section uses shallow pool structure, reduces
Glass metal flow layer thickness, bubble efflux time shorten, and are more advantageous to the homogenizing of glass metal and the discharge of microbubble；
2, weir device is arranged: ultra-clear glasses will often replace calender according to service condition, and more replacements are arranged in channel
Number is more frequent, according to setting port number difference extraction fluctuating range between 20%-50%, causes glass metal quality significantly
Fluctuation, in response to this problem, is arranged weir in melting furnaces, by the way that the stream that weir changes glass liquid stream is rationally arranged in melting furnaces bottom of pond
It is dynamic, bottom of pond temperature can be reduced, the regurgitant volume of glass metal after clarification, homogenizing is reduced, weakens back-flow velocity, stable liquid stream is played and makees
With, to improve the quality of melting capacity and glass metal, melting furnaces energy consumption is reduced, it, can be preferably when extraction appearance is substantially gone up and down
Play the role of stabilized glass liquid liquid stream；
3, bubbling device is set: effectively blocking in bottom of pond retention layer non-molten batch material in melting furnaces after setting weir to going out
Card neck flows at material mouth, bubbling device is arranged in conjunction with weir, elongate in shape and circular hole enhance convection current for bottom of pond on bubbling device
Temperature of glass liquid improves, and largely reduces viscous layer, and bring no cofusing particle into high-temperature region and melted, and reduces calculus rate, can
Hot(test)-spot temperature is reduced, melting efficiency is improved, accelerates the clarification and homogenization of glass, as can be seen from the above the program has operation letter
Just, practical feature.
