Description

유리용융로{GLASS FURNACE}Glass Melting Furnace {GLASS FURNACE}

본 발명은, 유리용융로에 관한 것으로서, 보다 상세하게는, 유리물의 하부층이 성형장치에 공급되는 것을 감소시킴으로써 성형될 유리제품의 품질을 향상시킬 수 있는 유리용융로에 관한 것이다.The present invention relates to a glass melting furnace, and more particularly, to a glass melting furnace that can improve the quality of the glass product to be molded by reducing the supply of the lower layer of the glass to the molding apparatus.

일반적으로 유리용융로라 함은 고상의 유리원료를 가열 및 청징하여 액상으로 만들고 이를 교반 및 가열하여 유리제품을 성형하는 성형장치로 공급되기까지의 공정내에 구비된 설비 전체를 일컫는다.In general, the glass melting furnace refers to the entire equipment provided in the process of heating and clarifying a solid glass raw material into a liquid phase, and stirring and heating the glass raw material to be supplied to a molding apparatus for molding a glass product.

액상의 유리물이 형성되기까지는 고상의 유리원료를 공급받아 약 1500 ~ 1600℃로 가열하여 용해시키는 용해로와, 용해로에서 용해된 유리물을 약 1100 ~ 1200℃로 유지시키면서 청징하는 청징부를 거치게 되며, 용해로 및 청징부를 거쳐 액상으로 형성된 유리물은 피더라는 유로를 통해 소정의 온도구배 및 점성을 유지하며 이동하여 보울을 통해 성형장치로 공급되어 진다.Until a liquid glass material is formed, it passes through a melting furnace which receives solid glass raw material and heats it to about 1500 to 1600 ° C, and clarifies the glass material dissolved in the melting furnace while maintaining the glass material at about 1100 to 1200 ° C. The glass formed in the liquid phase through the melting furnace and the clarification part is moved to maintain a predetermined temperature gradient and viscosity through a flow path called a feeder is supplied to the molding apparatus through the bowl.

이와 같이, 용해로와 성형장치 사이에 개재되어 액상의 유리물이 유동되는 유로를 형성하는 피더에는 가열장치 및 교반장치들이 구비되어 유리물의 높이층에 따라 발생되는 상부층과 하부층간의 점성 및 온도차를 균일하게 유지시키게 된다.As such, the feeder interposed between the melting furnace and the forming apparatus to form a flow path through which the liquid glass material flows is provided with a heating device and a stirring device to uniformly vary the viscosity and temperature difference between the upper layer and the lower layer generated according to the height layer of the glass material. Will be maintained.

그런데, 이러한 종래의 유리용융로에 있어서는, 가열장치 및 교반장치에 의해서도 균질화가 되지 못한 유리물의 하부층이 그대로 성형장치에 공급되어 성형될 유리제품의 품질을 저해시킨다는 문제점이 있다.By the way, in the conventional glass melting furnace, there is a problem that the lower layer of the glass material, which is not homogenized even by the heating device and the stirring device, is supplied to the molding apparatus as it is, thereby impairing the quality of the glass product to be molded.

즉, 피더내에서 유동되는 유리물은 소정의 높이를 갖고 있으므로 비중이 큰 각종 이물질들은 하중에 의해 자연히 하부층으로 가라앉게 된다. 또한, 유리물의 온도구배를 유지하기 위해 피더에 설치된 가열장치 역시 피더의 상부면에 배치되어 있으므로 유리물의 하부층은 상부층에 비해 온도가 낮을 뿐만 아니라 점성이 높은 관계로 유동속도가 느리게 된다.That is, since the glass material flowing in the feeder has a predetermined height, various foreign substances having a high specific gravity naturally sink to the lower layer by the load. In addition, since the heating device installed in the feeder to maintain the temperature gradient of the glass is also disposed on the upper surface of the feeder, the lower layer of the glass is not only lower in temperature than the upper layer but also has a high viscosity and thus a slow flow rate.

따라서, 피더내에 설치된 다수개의 교반장치를 통해 유리물의 상부층과 하부층을 교반시키기는 하나, 회전하며 유리물의 상부 및 하부층을 뒤섞는 교반장치 또한 피더의 저부면에 근접하게 위치되어 있을 뿐 저부면에 접촉되도록 설치할 수 없으므로 피더의 저부면에 위치된 유리물의 하부층은 그 상부층과 교반되지 못한 채, 저부면을 따라 느리게 유동하여 결국에는 성형장치에 공급되게 된다.Therefore, while stirring the upper and lower layers of the glass through a plurality of stirring devices installed in the feeder, the stirring device, which rotates and mixes the upper and lower layers of the glass, is also located in close proximity to the bottom of the feeder and in contact with the bottom. Since it cannot be installed, the lower layer of glass located at the bottom of the feeder flows slowly along the bottom without being stirred with the upper layer and is eventually supplied to the molding apparatus.

이와 같이, 피더의 저부면을 따라 유동된 유리물의 하부층은 일정한 온도구배 및 점성을 가지지 못하기 때문에 성형될 유리제품의 품질에 막대한 지장을 초래하게 된다.As such, the lower layer of glass flowing along the bottom surface of the feeder does not have a constant temperature gradient and viscosity, resulting in enormous disruption to the quality of the glass product to be molded.

따라서, 본 발명의 목적은, 유리물의 하부층이 성형장치에 공급되는 것을 감소시킴으로써 성형될 유리제품의 품질을 향상시킬 수 있는 유리용융로를 제공하는 것이다.It is therefore an object of the present invention to provide a glass melting furnace which can improve the quality of the glass article to be molded by reducing the supply of the lower layer of glass to the molding apparatus.

상기 목적은, 본 발명에 따라, 유리원료를 액상으로 가열하는 용해로와, 상기 용해로에서 제공된 액상의 유리물이 유동되는 피더와, 상기 피더의 단부영역에 결합되어 상기 유리물을 성형장치에 공급하는 보울을 구비한 유리용융로에 있어서, 상기 피더의 저부면에 마련되어 상기 보울을 향해 유동되는 상기 유리물의 하부층의 유동속도를 억제시키는 저항수단을 포함하는 것을 특징으로 하는 유리용융로에 의해 달성된다.The object is, according to the invention, the melting furnace for heating the glass raw material in the liquid phase, the feeder in which the liquid glass material provided in the melting furnace flows, and is coupled to the end region of the feeder to supply the glass material to the molding apparatus A glass melting furnace provided with a bowl, the glass melting furnace comprising resistance means for suppressing the flow rate of the lower layer of the glass material flowing toward the bowl provided on the bottom surface of the feeder.

여기서, 상기 저항수단은, 상기 저부면으로부터 상향 돌출된 적어도 하나의 멈춤턱인 것이 효과적이다.Here, it is effective that the resistance means is at least one stop projection protruding upward from the bottom surface.

또한, 상기 저부면은 상기 보울을 향해 점진적으로 경사각이 높아지도록 형성된 것이 바람직하다.In addition, the bottom surface is preferably formed such that the angle of inclination gradually increases toward the bowl.

이하에서는 첨부도면을 참조하여 본 발명에 대해 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 유리용융로의 피더영역의 개략적인 측단면도이며, 도 2는 본 발명에 따른 피더영역의 다른 실시예를 도시한 측단면도이다. 이들 도면에 도시된 바와 같이, 유리물이 유동될 수 있도록 유로(16)를 가진 피더(10)의 단부영역에는 유리물을 일정량만큼 성형장치(미도시)에 공급하는 보울(12)이 결합되어 있으며, 피더(10)와 보울(12)의 외측벽은 내화벽돌로 형성되어 있다.1 is a schematic side cross-sectional view of a feeder region of a glass melting furnace according to the present invention, Figure 2 is a side cross-sectional view showing another embodiment of the feeder region according to the present invention. As shown in these figures, a bowl 12 for supplying a certain amount of glass to a forming apparatus (not shown) is coupled to an end region of the feeder 10 having a flow path 16 so that the glass can flow. The outer walls of the feeder 10 and the bowl 12 are formed of refractory bricks.

피더(10)의 상부벽(14)에는 다수개의 관통공(20)이 형성되어 있으며, 이 관통공(20)에는 도시 않은 상측의 구동부에 결합되어 이 구동부로 인해 회전하면서 피더(10)내의 유리물의 상부층과 하부층을 교반하는 교반기(18)가 기립되게 설치되어 있다.A plurality of through holes 20 are formed in the upper wall 14 of the feeder 10, and the through holes 20 are coupled to an upper driving part (not shown) and rotated by the driving parts, thereby rotating the glass in the feeder 10. The stirrer 18 which stirs the upper layer and the lower layer of water is provided to stand up.

한편, 피더(10)의 저부면(24)은 보울(12)을 향해 소정의 경사각(θ)을 갖도록 형성되어 있을 뿐만 아니라, 도 2에 도시된 바와 같이, 저부면(24)으로부터 상향 돌출된 다수의 걸림턱(22)이 형성되어 있다.On the other hand, the bottom surface 24 of the feeder 10 is formed to have a predetermined inclination angle θ toward the bowl 12, as shown in Figure 2, protrudes upward from the bottom surface 24 A plurality of locking jaws 22 are formed.

이상과 같은 구성에 의하여, 도시 않은 용해로와 청징부를 거쳐 액상으로 형성된 유리물은 피더(10)의 유로(16)를 경유하여 보울(12)을 통해 성형장치로 일정량만큼 공급되게 된다.By the above configuration, the glass material formed in the liquid phase through the melting furnace and the clarification unit not shown is supplied to the molding apparatus through the bowl 12 via the flow path 16 of the feeder 10 by a predetermined amount.

유리물이 피더(10)내에서 유동되는 동안, 유리물은 피더(10)의 상부벽(14)에 마련된 도시 않은 가열버너에 의해 소정의 온도구배를 유지할 수 있게 되며, 다수의 교반기(18)에 의해 유리물의 상부 및 하부층은 적절히 교반되게 된다.While the glass water flows in the feeder 10, the glass water can be maintained at a predetermined temperature gradient by a heating burner (not shown) provided on the upper wall 14 of the feeder 10, a plurality of agitators 18 This causes the upper and lower layers of the glass to be stirred properly.

그러나, 종래기술에서 상술한 바와 같이, 교반기(18)에 의해서도 교반되지 못한 유리물의 하부층은 상부층에 비해 온도가 낮고 비중이 큰 이물질의 정체로 인해 그 유동속도가 느리기 때문에 도 1에서와 같이 피더(10)의 저부면(24)에 기울기(θ)를 부여함으로써 유리물의 하부층의 유속을 더욱 감소시켜 유리물의 하부층이 성형장치에 공급되는 것을 방지시킬 수 있게 된다.However, as described above in the prior art, the lower layer of the glass that was not stirred even by the stirrer 18 has a lower feed temperature than the upper layer and its flow rate is slow due to the stagnation of foreign matter having a large specific gravity, so that the feeder ( By providing the inclination θ to the bottom surface 24 of 10), the flow rate of the lower layer of the glass can be further reduced to prevent the lower layer of the glass from being supplied to the molding apparatus.

또한, 도 2에서와 같이, 피더(10)의 저부면(24)에 상향 돌출된 걸림턱(22)을 형성함으로써 유리물의 하부층이 걸림턱(22)에 의해 거의 유동되지 못하도록 하여 양질의 유리물인 상부층과 중간층만이 성형장치에 공급되도록 하여 성형될 유리제품의 품질을 향상시킬 수 있을 뿐만 아니라 어느 정도의 시간경과 후에 걸림턱(22)에 의해 정체되어 있던 유리물의 하부층이 주위의 유리물들의 유속으로 인해 걸림턱(22)으로부터 소정 상승되어 유동하게 되면 교반기(18)에 의해 교반될 수 있는 위치에 놓이게 됨으로써 양질의 유리물인 상부층과 적절히 교반되어 성형장치에 공급되게 된다.In addition, as shown in Figure 2, by forming a locking projection 22 protruding upward on the bottom surface 24 of the feeder 10 so that the lower layer of the glass is hardly flowed by the locking projection 22 is a good glass material Only the upper layer and the middle layer can be supplied to the molding apparatus to improve the quality of the glass product to be molded, but also the lower layer of the glass which has been stagnated by the latching jaw 22 after a certain time has elapsed. Due to the predetermined rise from the locking step 22 is placed in a position that can be stirred by the stirrer 18 is properly stirred with the upper layer of the high quality glass material is supplied to the molding apparatus.

전술 및 도시한 실시예에서는 피더의 저부면에 경사각을 부여하는 것과 저부면에 멈춤턱을 돌출형성시키는 것에 관하여 각각의 도면에 도시하였으나, 소정의 경사각을 갖는 저부면에 복수개의 멈춤턱을 형성하면 더욱 뛰어난 효과를 거둘 수 있음은 물론이다.In the above-described and illustrated embodiments, although each of the drawings is illustrated in terms of giving an inclination angle to the bottom surface of the feeder and protruding the stopper on the bottom surface, a plurality of stoppers are formed on the bottom surface having a predetermined inclination angle. Of course, the effect can be more excellent.

이상 설명한 바와 같이, 본 발명에 따르면, 유리물의 하부층이 성형장치에 공급되는 것을 감소시킴으로써 성형될 유리제품의 품질을 향상시킬 수 있는 유리용융로가 제공된다.As described above, according to the present invention, there is provided a glass melting furnace that can improve the quality of the glass product to be molded by reducing the supply of the lower layer of glass to the molding apparatus.
