現在ルツボ型ガラス溶融電気炉は単独炉として
使用されているが、電気加熱におけるむだな熱量
は炉壁よりの放散、煉瓦、ルツボ等の蓄熱、ルツ
ボ開口部よりの放熱、送電ロス、等であるがガラ
ス溶融の場合は炉温を大きく下げる事はないので
煉瓦、ルツボ等の蓄熱は無視出来るので、炉壁よ
りの放散がむだな熱量の中での割合いはもつとも
大きくなる。そこで各電気炉の横壁又は後壁を共
有させる事によりその部分よりの放散熱量をゼロ
にすれば非常に大きな熱エネルギーの節約となり
放散熱量が減る事により炉の電気容量も小さくて
よく、電気加熱器及び電源装置も小さなものとな
り電気炉の契約電力も少くなる。又壁を共有して
いるのでそれだけ使用炉材及び金物等も少くなる
ので炉の製造費も安価なものとなる。この様に多
連式ルツボ型ガラス溶融電気炉は非常に熱経済性
を高く、電気炉全体の設備費を安く押える事の出
来る考案である。[Detailed explanation of the invention] Currently, crucible-type glass melting electric furnaces are used as stand-alone furnaces, but the amount of wasted heat during electric heating is dissipated from the furnace wall, heat is stored in bricks, crucibles, etc., and heat is radiated from the crucible opening. , power transmission loss, etc. However, in the case of glass melting, the furnace temperature does not drop significantly, so the heat accumulation in bricks, crucibles, etc. can be ignored, so the radiation from the furnace wall accounts for the proportion of wasted heat. growing. Therefore, if the side wall or rear wall of each electric furnace is shared, and the amount of heat dissipated from that part is reduced to zero, a large amount of thermal energy can be saved.As the amount of heat dissipated is reduced, the electric capacity of the furnace can be small, and electric heating The equipment and power supply equipment are also smaller, and the contract power for the electric furnace is also reduced. Furthermore, since the walls are shared, fewer furnace materials and hardware are used, which reduces the manufacturing cost of the furnace. As described above, the multiple crucible type glass melting electric furnace has extremely high thermoeconomic efficiency and is a device that can keep the equipment cost of the entire electric furnace low.

１部が開口した細長い直方体の枠体１を製作し、
その中に煉瓦２にて炉床、炉壁を築き複数個の部
屋が出来る様に仕切壁１１を設け、各部屋の前面
上部中心位置にルツボ口が出る様凹型の開口部を
設ける。各部屋の両側面に複数個の電気加熱器８
を装着し、湯抜き穴４を明け、ルツボ台３を構築
し電気炉Ｆを構成する。鋼板にて天井枠体５を製
作しその下面にフツク６を取り付け、耐火セメン
ト１０にて天井部を築造し各部屋別に独立した天
井Ｈを構成する。先ず、天井Ｈを別の場所に置
き、ルツボ７をルツボ口が電気炉Ｆの開口部へ出
る様にルツボ台３の上に載置し天井Ｈを電気炉Ｆ
に取り付け、ルツボ口の周囲のすきまをモルタル

電対を取り付け温度制御するものである。 The structure of the glass melting furnace for ceiling opening/closing type cat pot which was filed by the applicant in October 1983 in Utility Application No. 161258 will be explained based on the drawing as an example of the present invention. A frame 1 of a long and narrow rectangular parallelepiped with openings at the top and the front part is manufactured,
A hearth and a hearth wall are made of bricks 2, and a partition wall 11 is provided so as to form a plurality of rooms, and a concave opening is provided at the center of the upper front of each room so that the crucible mouth can come out. Multiple electric heaters 8 on both sides of each room
is installed, a drain hole 4 is made, a crucible stand 3 is constructed, and an electric furnace F is constructed. A ceiling frame body 5 is made of a steel plate, a hook 6 is attached to its lower surface, and a ceiling part is constructed of fireproof cement 10 to constitute an independent ceiling H for each room. First, place the ceiling H in a different place, place the crucible 7 on the crucible stand 3 so that the crucible mouth comes out to the opening of the electric furnace F, and place the ceiling H in the electric furnace F.
, and fill the gap around the crucible mouth with mortar 9. Although not shown, thermocouples are installed in each room to control the temperature.
以上の様に構成した多連式ルツボ型ガラス溶融
電気炉は各部屋は独立しているので個々に温度の
設定が出来、又ルツボの取替えもその部屋の温度
を下げて天井Ｈを取り去り行なえるので安全であ
り、不要な部屋は使用しない事も出来るという便
利で熱率の高い製造費の安価なものである。 In the multi-crucible glass melting electric furnace configured as described above, each room is independent, so the temperature can be set individually, and crucibles can be replaced by lowering the temperature of the room and removing the ceiling H. Therefore, it is safe, it is convenient because unnecessary rooms can be left unused, and it has a high heat rate and is inexpensive to manufacture.
