本発明は、焼却灰の如き誘電体にマイクロ波を照射して
これを加熱溶融するマイクロ波溶融炉において、湯口内
溶融物の固化による湯口の閉塞を防止するために、湯口
内溶融物を再加熱する装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention is aimed at preventing blockage of the sprue due to solidification of molten material in the sprue in a microwave melting furnace that heats and melts a dielectric material such as incineration ash by irradiating it with microwaves. , relates to a device for reheating a molten material in a sprue.
加熱溶融炉においては、湯口から排出される溶融物が温
度低下により湯口内で固化し、溶融物の湯口からの流出
を止めてしまうことがある。In a heating melting furnace, the molten material discharged from the sprue may solidify within the sprue due to a drop in temperature, and the flow of the molten material from the sprue may be stopped.
従来湯口内で固化した被溶融物を再溶融するため、バー
ナ等による加熱方式が行われていた。Conventionally, a heating method using a burner or the like has been used to remelt the material that has solidified in the sprue.
しかしながら、バーナによる加熱の場合には、湯口内溶
融物のみでなく周辺機器類をも同時に加熱せざるを得す
、加熱部位の劣化につながると共に非効率的である。However, in the case of heating with a burner, it is necessary to heat not only the molten material in the sprue but also peripheral equipment at the same time, which leads to deterioration of the heating area and is inefficient.
また、溶融物が誘電体である場合には同時に断熱質であ
るため加熱効率か悪い難点がある。Furthermore, when the melt is a dielectric, it is also adiabatic and has the disadvantage of poor heating efficiency.
本発明は従来の湯口内溶融物の加熱方法の上記のような
問題点に着目してなされたもので、高周波による誘電加
熱で湯口内の溶融物のみをそれ自身昇温させて溶融させ

ある。A circular hole 4a is formed in the upper part of the tip of the waveguide 4 connected to another or the aforementioned microwave single-wave power source (not shown), and the tip of the sprue 1a of the retort 1 faces into this circular hole, and the lower part of the circular hole A notch 4b is formed in the hole, through which molten metal can be dripped.
導波管先端の対向内側面にはマイクロ波シール板５が突
設され、マイクロ波はここでシールされ、湯口１ａへ照
射される。A microwave seal plate 5 is provided protruding from the opposite inner surface of the tip of the waveguide, and the microwave is sealed here and irradiated to the sprue 1a.
次に作用を説明する。Next, the action will be explained.
温度低下により湯口１ａ内で溶融物が固化し、湯口か閉
塞された場合、導波管４を通してマイクロ波が湯口へ照
射され、湯口内の溶融物が誘電力蔗されて再溶融し、湯
口から流れ出す。When the molten material solidifies in the sprue 1a due to a drop in temperature and the sprue is blocked, microwaves are irradiated to the sprue through the waveguide 4, and the molten material in the sprue is remelted by a dielectric power, and is removed from the sprue. It starts to flow.
湯口は開口し、レトルト１内の湯は連続的に排出される
。The sprue is opened and the hot water in the retort 1 is continuously discharged.
以上要するに本発明は、湯口１ａ内で固化した溶融物へ
マイクロ波を照射してこれを誘電加熱してこれを再溶融
