Description
본 발명은 유리를 용융(鎔融)시키기 위한 전기로(電氣爐)에 관한 것으로서, 특히 고품질의 유리제품을 성형할 수 있고 도가니의 교체가 용이하면서도 환경공해를 방지할 수 있도록 한 발명에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric furnace for melting glass, and more particularly to an invention in which a glass product of high quality can be molded, and a crucible can be easily replaced while preventing environmental pollution. .
일반적으로 유리를 용해시키는 용해로는 내화 벽돌로 이루어진 가마의 내부에 여러개의 도가니를 배치시키고 중유(주로 벙커-c 유)를 연료로 사용하여 도가니를 가열시킴에 따라 도가니의 내부에 담겨진 유리를 용융시킬 수 있도록 되어 있다.In general, melting furnaces for dissolving glass are disposed of various crucibles in a kiln made of refractory bricks, and the fuel contained in the crucible is melted by heating the crucible by using heavy oil (mainly bunker-c oil) as a fuel. It is supposed to be.
그러나, 전술한 바와 같이 도가니를 가열하기 위하여 중유를 연소시키면 상당한 공해물질이 발생되어 대기의 환경을 나쁘게하고, 가마 내부의 열의 분포가 고르게 이루어지지 않는 등의 폐단이 발생되었다.However, as described above, combustion of heavy oil to heat the crucible generates considerable pollutants, resulting in a bad air environment, and a closed end such as uneven distribution of heat inside the kiln.
따라서, 중유의 연소시 발생되는 그을음과 고르지 않는 열의 분포에 의하여 고품질의 유리제품을 성형할 수 없었으며, 특히 열효율이 낮게 형성되어 전체적인 연료의 소비량이 많아지는 등의 문제점이 있었다.Therefore, high quality glass products could not be formed by soot and uneven heat distribution generated during the combustion of heavy oil, and in particular, the thermal efficiency was low and the overall fuel consumption was increased.
또한, 가마 내부에 배치된 도가니의 유리가 완전히 용해되면 가마의 벽돌 일부를 헐어내고 도가니를 인출하는 방식으로 되어 있는 것이므로 가마의 유지 관리와 그 사용이 매우 불편하였으며, 전체적으로 도가니를 고르게 가열시킬 수 없는 것이므로 열의 편차에 의하여 도가니의 수명이 현저하게 저하되는 등의 폐단이 있었다.In addition, when the glass of the crucible placed inside the kiln is completely dissolved, it is a way to tear off the brick part of the kiln and draw out the crucible, which makes the maintenance and use of the kiln very inconvenient, and the whole crucible cannot be heated evenly. As a result, the life of the crucible was markedly reduced due to heat variation.
본 발명은 상기한 문제점을 감안하여 창안한 것으로서, 그 목적은 공해물질이 발생되지 않고, 열효율이 높으며, 가마와 도가니의 유지관리가 매우 편리한 유리 용해용 전기로를 제공함에 있는 것이다.The present invention has been made in view of the above-described problems, and an object thereof is to provide an electric furnace for glass melting, which does not generate pollutants, has high thermal efficiency, and is very convenient for maintenance of kilns and crucibles.
상기한 목적을 달성하기 위한 본 발명의 특징은,Features of the present invention for achieving the above object,
단열벽돌(10a) 내측에 내화벽돌(10b)이 적층된 가마(10)의 전면과 하부에는 투시창(11a)을 갖는 개폐문(11)과 배출구(12)가 각각 형성되고, 가마(10) 내부에 보관된 도가니(20)의 주위에는 복수개의 전열선 히터(30)들이 일정 간격으로 장착됨을 특징으로 하는 유리 용해용 전기로에 의하여 달성될 수 있는 것이다.In the front and bottom of the kiln 10 in which the firebrick 10b is stacked inside the heat insulating brick 10a, an opening and closing door 11 and an outlet 12 having a viewing window 11a are formed, respectively, in the kiln 10. Around the crucible 20 stored can be achieved by a glass melting electric furnace, characterized in that a plurality of heating wire heaters 30 are mounted at regular intervals.

이하, 상기한 목적을 달성하기 위한 바람직한 본 발명의 실시예를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention for achieving the above object is as follows.
도 1 내지는 도 3에서 도시한 바와 같이,As shown in Figures 1 to 3,
본 발명에 의한 가마(10)는 단열벽돌(10a) 내측에 내화벽돌(10b)이 적층된 형태로되어 있고, 가마(10)의 전면에는 투시창(11a)이 형성된 개폐문(11)이 결합되어 여닫을 수 있도록 구성된다.The kiln 10 according to the present invention has a form in which firebrick 10b is stacked inside a heat insulating brick 10a, and an opening and closing door 11 having a viewing window 11a is coupled to the front of the kiln 10 to open and close. It is configured to be.
상기 가마(10)의 하부에는 배출구(12)가 형성되어 도가니(20)에서 용해된 상태로 누출되는 유리 지꺼기들을 배출시킬 수 있도록 되어 있다.An outlet 12 is formed at the bottom of the kiln 10 so as to discharge the glass debris leaking in the dissolved state in the crucible 20.
상기 가마(10)의 내부에는 도가니(20)가 삽입되어 있고, 도가니(20)의 입구(21)는 가마(10)의 투시창(11a)을 향하도록 도가니(20)가 놓여진다. 물론 도가니(20)의 입구(21)에는 뚜껑(21a)이 착탈식으로 결합된다.The crucible 20 is inserted into the kiln 10, and the crucible 20 is placed so that the inlet 21 of the crucible 20 faces the viewing window 11a of the kiln 10. Of course, the lid 21a is detachably coupled to the inlet 21 of the crucible 20.
상기 가마(10) 내부에는 복수개의 전열선 히터(30)들이 일정 간격으로 장착되어 있고, 이 히터(30)들은 원형으로 배열되어 도가니(20)의 주위에서 일정간격을 이격하여 장착된다. 물론, 상기 전열선 히터(30)는 전원을 인가 받으면 고온으로 발열되는 구성으로 되어 있음은 당연하다.Inside the kiln 10, a plurality of heating wire heaters 30 are mounted at regular intervals, and the heaters 30 are arranged in a circle and spaced apart at a predetermined interval around the crucible 20. Of course, the heating wire heater 30 is of course configured to generate heat at a high temperature when the power is applied.
전술한 구성으로 이루어진 본 발명의 전기로는 도가니(20)의 주위에서 일정간격으로 배열된 복수개의 전열선 히터(30)에 의하여 도가니(20)가 지속적이고 고르게 가열되므로 열효율을 극대화시킬 수 있는 동시에 도가니(20)의 가열시 공해물질이 전혀 발생되지 않는 것이므로 환경공해의 방지에 이바지 할 수 있는 등의 이점이 있다.The electric furnace of the present invention having the above-described configuration can be maximized thermal efficiency since the crucible 20 is continuously and evenly heated by a plurality of heating wire heaters 30 arranged at regular intervals around the crucible 20. Since no pollutants are generated during the heating of 20), there is an advantage that it can contribute to the prevention of environmental pollution.
이와 같이 도가니(20)가 전체적으로 고르게 가열되면서도 가열시 그을음이 전혀 발생되지 않는 본 발명의 전기로는 고품질의 유리제품을 성형할 수 있는 이점이 있는 동시에, 열효율이 극대화되면서도 비용이 저렴한 심야 전력등을 적극 활용할 수 있는 것이므로 전체적인 전력의 사용량을 최소화시킬 수 있는 것으로서 유리 제품의 대외 경쟁력을 최대한 높여줄 수 있는 것이다.As such, the furnace 20 of the present invention does not generate soot upon heating even though the crucible 20 is heated evenly as a whole, and has the advantage of forming a high-quality glass product, while maximizing thermal efficiency and inexpensive midnight electric power. As it can be utilized, it is possible to minimize the overall power consumption, which can maximize the external competitiveness of glass products.
또한, 가마(10) 내부에 보관된 도가니(20)의 유리가 완전히 용해되면 가마(10)의 개폐문(11)을 열고 간편하게 도가니(20)를 인출하여 용융된 유리를 제품으로 성형할 수 있는 것이므로 도가니(20)의 교체작업이 매우 편리하면서도 적은인원으로도 가마(10)를 유지 관리할 수 있는 등의 이점이 있다.In addition, when the glass of the crucible 20 stored inside the kiln 10 is completely dissolved, the opening and closing door 11 of the kiln 10 is opened and the crucible 20 can be easily pulled out to form molten glass into a product. Although the replacement work of the crucible 20 is very convenient, there is an advantage such that the kiln 10 can be maintained even with a small number of people.
물론, 도가니(20)가 전체적으로 고르게 가열되면 온도의 분포가 균일하게 형성되어 도가니(20)의 수명을 상당기간 연장시켜 줄 수 있음은 당연하다.Of course, when the crucible 20 is heated evenly as a whole, it is natural that the temperature distribution is uniformly formed, thereby extending the life of the crucible 20 for a considerable period of time.
이상에서 상술한 바와 같은 본 발명은, 단열벽돌(10a) 내측에 내화벽돌(10b)이 적층된 가마(10)의 전면과 하부에는 투시창(11a)을 갖는 개폐문(11)과 배출구(12)가 각각 형성되고, 가마(10) 내부에 보관된 도가니(20)의 주위에는 복수개의 전열선 히터(30)들이 장착된 유리 용해용 전기로를 구성토록 함으로써, 상기 도가니(20)의 주위에서 일정간격으로 배열된 복수개의 전열선 히터(30)에 의하여 도가니(20)가 지속적이고 고르게 가열되므로 열효율이 극대화되어 고품질의 유리제품을 성형할 수 있는 동시에 전력의 사용량을 최소화시킬 수 있고, 도가니(20)의 가열시 공해물질이 전혀 발생되지 않는 것으로서 환경공해의 방지에 크게 기여할 수 있는 등의 이점이 있다.In the present invention as described above, the front and bottom of the kiln 10 in which the firebrick 10b is stacked inside the heat insulating brick 10a, the opening and closing door 11 and the outlet 12 having the viewing window 11a are provided. The glass melting furnaces, each of which is formed and equipped with a plurality of heating wire heaters 30, are arranged around the crucible 20 stored in the kiln 10, and are arranged at a predetermined interval around the crucible 20. Since the crucible 20 is continuously and evenly heated by the plurality of heated wire heaters 30, the thermal efficiency is maximized, thereby forming high quality glass products, and minimizing the amount of power used, when heating the crucible 20. Since no pollutants are generated, there is an advantage that can greatly contribute to the prevention of environmental pollution.
