となっていた。In addition, in conventional cooling tanks that use water, the water is discharged from the cooling tank before it evaporates, and the vibrator inside the high-temperature melt is always immersed in water at a temperature of 100°C or less, so there is a high temperature around the vibrator. This results in solidification of the molten material, lowering the heat exchange rate, and, like a cooling tank that uses air, it takes about one hour to cool the high-temperature molten material by 10 degrees Celsius.

Furthermore, since the latent heat from dew to steam is as high as the latent heat from water to steam, the heat exchange rate is high and the temperature of the high-temperature molten material can be lowered in a short time.

〈実施例〉 以下、この発明の一実施例を図面に基づいて説明する。<Example> Hereinafter, one embodiment of the present invention will be described based on the drawings.

からなるバイブ３を備えている。なお、この冷却槽１は
、熱処理炉の冷却槽として使用されるものであり５熱処
理物の投入に邪魔とならないよう、バイブ３が４ｒＩ！
１の壁付近に設けられている。The cooling tank 1 of the embodiment shown in FIG. 1 is equipped with a tank body 2 for storing a high-temperature molten body, as in the conventional case, and is made of heat-resistant steel such as stainless steel bent and buried in the high-temperature molten body. It is equipped with a vibe 3. Note that this cooling tank 1 is used as a cooling tank for a heat treatment furnace, and the vibrator 3 is placed in the 4rI!
It is located near the 1st wall.
バイブ３は、所定形状のものが継いで形成されており、
両端を槽本体２から突出させている。そして、バイブ３
の一端には、エアを送る送風機４が配設されるとともに

されている。The vibrator 3 is formed by joining pieces of a predetermined shape,
Both ends protrude from the tank body 2. And vibe 3
A blower 4 that sends air is disposed at one end, and a fog generator 5 that makes water mist is disposed downstream of the blower 4.

状にするものである。The fog generator 5 is connected to a conduit 7 through which water is supplied, and an accumulator 12 and a compressor 11 to generate high pressure (4 to a
A pipe line 8 to which air of kgf10n') is supplied, and a pipe line 7
- A pipe line 6 where the pipes 8 and 8 are joined and connected to the vibrator 3, and when the solenoid valves 9 and 10 of the pipes 7 and 8 are respectively opened, the pipes are closed by high pressure air from the pipe line 8. The water from 7 is made into dew.
また、バイブ３の他端は、熱処理炉から離れた屋外に開
口されている。Further, the other end of the vibrator 3 is opened outdoors away from the heat treatment furnace.
なお、１３は温度センサであり、電磁弁９・１０・送風

構成されている。In addition, 13 is a temperature sensor, which is connected to a predetermined temperature adjustment circuit (not shown) together with the solenoid valves 9, 10, and the blower 4, and this temperature adjustment circuit inputs the signal from the temperature sensor 13 and controls the solenoid valve. 9 and 10 and the blower 4 are operated to lower the temperature of the high-temperature melt to a predetermined set temperature.
この冷却槽１の作動態様について述べれば、図示しない

ている。Regarding the operating mode of this cooling tank 1, if a set temperature for lowering the temperature is input to a temperature adjustment circuit (not shown),
The blower 4 is automatically activated and the solenoid valves 9 and 10 are opened. Incidentally, the compressor 11 is already in operation, and high-pressure air is stored in the accumulator 12.
そして、電磁弁９・１０が開くと、管路７からの水が管
路８からの高圧のエアによって霧状にされ、その露が管
路６を経てパイプ３内に入る。その後、露は、送風機４

ブ３の他端から排出される。When the electromagnetic valves 9 and 10 open, the water from the pipe 7 is atomized by high-pressure air from the pipe 8, and the dew enters the pipe 3 through the pipe 6. After that, the dew is removed by blower 4.
The air passes through the vibrator 3 and turns into steam due to the high temperature of the high-temperature molten material in the tank body 2, and is discharged from the other end of the vibrator 3.
その際、霧が蒸気となることによって高温溶融体りから
熱を奪い、高温溶融体りを降温させることとなる。At this time, the fog turns into steam, which removes heat from the high-temperature molten body and lowers the temperature of the high-temperature molten body.
そして、高温溶融体りが設定温度まで降温されると、温

に所定の信号を出力し、温度制御回路は、電磁弁９・１
０を閉じさせ、所定時間経過後に送風機４を停止させる
こととなる。なお電磁弁９・１０を閉じさせた後に送風
機４を停止させる理由は、バイブ３内の露や蒸気を全て
排出させるためであり、電磁弁９・１０を閉じさせた後

等によって適宜選定されている。When the temperature of the high-temperature molten material is lowered to a set temperature, the temperature sensor 13 senses it and outputs a predetermined signal to a temperature control circuit (not shown), which controls the solenoid valves 9 and 1.
0 is closed, and the blower 4 is stopped after a predetermined period of time has elapsed. The reason for stopping the blower 4 after closing the solenoid valves 9 and 10 is to exhaust all the dew and steam inside the vibrator 3, and stopping the blower 4 after closing the solenoid valves 9 and 10. The time required for this is appropriately selected depending on the length of the vibrator 3, etc.
したがって、実施例の冷却槽１では、バイブ３内を通過
するものが露であることから、バイブ３内で爆発する危
険性がなく、さらに、使用する水の量も少なくて済む。Therefore, in the cooling tank 1 of the embodiment, since what passes through the vibrator 3 is dew, there is no danger of an explosion within the vibrator 3, and furthermore, the amount of water used can be reduced.
また、バイブ３内で１００℃以上の蒸気にかわることが
できることから、１００℃以下の水を通す場合のような
バイブ３周囲に高温溶融体りが凝固することを防止する
ことができる。Furthermore, since the temperature can be changed to steam at 100° C. or higher within the vibrator 3, it is possible to prevent high-temperature molten material from solidifying around the vibrator 3, which would occur when water at a temperature of 100° C. or lower is passed through.
さらに、実施例の冷却槽１では、露から蒸気にかわる際

に、実施例の冷却槽１では、１０℃降温させるのに、高
温溶融体りを凝固させることなく、従来の約１７１０で
ある約６分で行なうことができた。Furthermore, the cooling tank 1 of the embodiment cools the high-temperature molten material by taking away the latent heat when dew changes to steam from the high-temperature molten material. Since it is similarly high, the heat exchange rate is high and the temperature of the high-temperature molten material can be lowered in a short time. Incidentally, in the cooling tank 1 of the example, it was possible to lower the temperature by 10° C. without solidifying the high-temperature molten material in about 6 minutes, which is about 1710 minutes compared to the conventional method.
なお、実施例の冷却槽１では、送風機４やコンプレッサ
１１からエアを吸引するものを示したが、高温溶融体り
が６００℃以上の温度では、酸素が混入されているとバ
イブ３等の各部品が酸化し易いことから、エアの替わり

。In the cooling tank 1 of the embodiment, air is sucked from the blower 4 and the compressor 11, but when the temperature of the high-temperature molten material exceeds 600°C, if oxygen is mixed in, each part of the vibrator 3 etc. Since the parts are easily oxidized, it is desirable to suck in an inert gas such as nitrogen gas instead of air.

We have shown devices that use high-pressure air, but there are also centrifugal spray devices that use centrifugal force to turn water into dew, such as those used in humidifiers, and centrifugal spray devices that use ultrasonic vibrations to turn water into dew. An ultrasonic atomizer or the like may also be used.
