Description
【０００１】
【発明の属する技術分野】
本発明は、誘導加熱方式によって加熱される反応槽内の被加熱物を効率的に冷却（加熱）することのできる誘導加熱式反応槽に関する。
【０００２】
【従来の技術】
従来から、種々の誘導加熱装置が知られており、その中でも効率のよい誘導加熱装置として、実公昭４７−２８９０６号公報に、金属製で内部に被加熱材料を収容する空洞を有する発熱体の外周に、周囲にコイルが捲かれた環状鉄心を発熱体を取り囲むようにして設置し、この環状鉄心の外方を通る導体で発熱体の所要発熱部位の両端部を短絡した誘導加熱装置が開示されている。
【０００３】
しかし、通常、誘導加熱装置自体は冷却機構を持たないので、加熱体自体を冷却する場合、別途誘導加熱装置の発熱体の内壁面に蛇管式冷却管を半割にして巻き、これを内壁面に直接溶接して、これに冷却水を通して内壁を直接冷却する方式が採られていた。
【０００４】
また、加熱体内の被加熱物を急速に冷却する場合は、外部冷却器にポンプで被加熱物を循環するか又は直接送って冷却する方式が採られていた。
【０００５】
【発明が解決しようとする課題】
しかしながら、上記前者の方式では、発熱体内壁に半割にした冷却管を直接溶接により固定するので、溶接作業が複雑で溶接の不具合が発生したり、また冷却管にも誘導二次電流が流れて加熱され、加熱冷却の繰り返しによる金属疲労により冷却管にクラックが発生したり、電食により腐食が生じたりすることにより、冷却水の漏洩が生じ易く、この冷却水の漏洩が誘導加熱装置の漏電事故につながり、運転継続不能はおろか装置自体が破損する恐れもあった。また、修理するためには、誘導加熱装置全体を分解しなければならないので、現実問題として修理は不可能であり、再製作する必要があった。
【０００６】
一方上記後者の方式では、外部冷却器を設置しなければならないので、装置全体が複雑化し、しかも外部冷却器および配管内に残存する不純物が多品種生産工程において問題となることが多かった。
【０００７】
本発明は、かかる従来の問題点を解消し、冷却水の漏洩による漏電事故の発生がなく、修理も容易な冷却機構を備えた誘導加熱式反応槽、及び外部冷却器を必要としない被加熱物を急速に冷却し得る冷却機構を備えた誘導加熱式反応槽の提供を課題とする。
【０００８】
【課題を解決するための手段】
上記課題は、誘導加熱装置により加熱される反応槽の外周部に冷却ジャケットを設けた誘導加熱式反応槽であって、前記誘導加熱装置は前記反応槽の外周部に設けられ、前記誘導加熱装置と前記冷却ジャケットとが離間分離されてなり、前記冷却ジャケットを、前記 誘導加熱装置を挟んで上下に配することを特徴とする誘導加熱式反応槽によって解決される。
好適には、前記誘導加熱装置を前記反応槽の外周に接して配置することができる。
【０００９】
【発明の実施の形態】
以下図面に従って本発明を詳細に説明すると、図１は、本発明に係わる誘導加熱式反応槽の実施例を示す縦断側面図で、同図の例では、反応槽４の外周に誘導加熱装置１をはさんで、その上下に冷却媒体が矢印の方向に流れる冷却ジャケット２及び３が設けてあり、これにより反応槽壁を加熱領域と冷却領域とに明確に分けている。
【００１０】
このような構造とすることにより、冷却管取り付けの複雑な溶接作業が不要となり、冷却水の漏洩による漏電事故の発生をなくすことができる。また、内部冷却管による冷却方式に比べて異常の発見や修理作業が極めて容易であり、維持コストを大幅に削減することが可能となる。また、冷却ジャケット２及び／又は冷却ジャケット３に冷却媒体（温水又は冷却水）を流し、同時に誘導加熱装置１による加熱を任意に行えば、加熱速度及び冷却速度を任意に変更できる。
【００１１】
【発明の効果】
上述のように、本発明によれば、冷却管取り付けの複雑な溶接作業が不要となり、冷却水の漏洩による漏電事故の発生をなくすことができ、更に、内部冷却管による冷却方式に比べて異常の発見や修理作業が極めて容易であり、維持コストを大幅に削減することが可能となる。また、加熱及び冷却速度が任意に変更することもしやすくなる。

BACKGROUND OF THE INVENTION
The present invention relates to an induction heating type reaction tank capable of efficiently cooling (heating) an object to be heated in a reaction tank heated by an induction heating method.
[0002]
[Prior art]
Conventionally, various induction heating devices are known. Among them, as an efficient induction heating device, Japanese Utility Model Publication No. 47-28906 discloses a heating element having a cavity made of metal and containing a material to be heated. An induction heating apparatus is disclosed in which an annular iron core with a coil around the outer periphery is installed so as to surround the heating element, and both ends of a required heating portion of the heating element are short-circuited by a conductor passing outside the annular iron core. Has been.
[0003]
However, since the induction heating device itself does not have a cooling mechanism, when the heating body itself is cooled, a coiled-type cooling pipe is separately halved around the inner wall surface of the heating element of the induction heating device, and this is wound on the inner wall surface. In this method, the inner wall is directly cooled by passing through the cooling water.
[0004]
In addition, when rapidly cooling an object to be heated in the heating body, a method of circulating the object to be heated with an external cooler with a pump or directly cooling the object to be heated has been adopted.
[0005]
[Problems to be solved by the invention]
However, in the former method, the halved cooling pipe is directly fixed to the heat generating body wall by direct welding, so that the welding operation is complicated and welding failure occurs, or an induced secondary current flows through the cooling pipe. When the cooling pipe is cracked due to metal fatigue due to repeated heating and cooling, or corrosion due to electrolytic corrosion occurs, leakage of the cooling water is likely to occur. This could lead to an electrical leakage accident, and the device itself could be damaged as well as inability to continue operation. In addition, in order to repair, the entire induction heating apparatus has to be disassembled. Therefore, as a practical problem, the repair is impossible and it is necessary to remanufacture.
[0006]
On the other hand, in the latter method, since an external cooler has to be installed, the entire apparatus is complicated, and impurities remaining in the external cooler and the piping often become a problem in a multi-product production process.
[0007]
The present invention eliminates the above-mentioned conventional problems, does not cause an electric leakage accident due to leakage of cooling water, and is an induction heating type reaction tank equipped with a cooling mechanism that is easy to repair, and does not require an external cooler. It is an object of the present invention to provide an induction heating reaction tank equipped with a cooling mechanism capable of rapidly cooling an object.
[0008]
[Means for Solving the Problems]
The above-mentioned problem is an induction heating type reaction tank provided with a cooling jacket in the outer peripheral part of the reaction tank heated by the induction heating apparatus, wherein the induction heating apparatus is provided in the outer peripheral part of the reaction tank, and the induction heating apparatus And the cooling jacket are separated from each other, and the cooling jacket is disposed above and below the induction heating device .
Preferably, it is possible to arrange the front Symbol induction heating device in contact with the outer periphery of the reaction vessel.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
The present invention will be described in detail below with reference to the drawings. FIG. 1 is a longitudinal side view showing an embodiment of an induction heating reaction tank according to the present invention. In the example of FIG. The
[0010]
By adopting such a structure, a complicated welding operation for mounting the cooling pipe becomes unnecessary, and the occurrence of a leakage accident due to leakage of cooling water can be eliminated. In addition, it is extremely easy to find abnormality and repair work as compared with the cooling method using the internal cooling pipe, and it is possible to greatly reduce the maintenance cost. Further, if a cooling medium (hot water or cooling water) is allowed to flow through the
[0011]
【The invention's effect】
As described above, according to the present invention, the complicated welding work for installing the cooling pipe is not required, the occurrence of an electric leakage accident due to the leakage of the cooling water can be eliminated, and moreover, abnormalities compared with the cooling system using the internal cooling pipe. It is extremely easy to find and repair the device, and the maintenance cost can be greatly reduced. Moreover, it becomes easy to change a heating and cooling rate arbitrarily.
