Description

電解槽１１は、加熱器２１ａおよび送風機２１ｂを備える。本実施の形態では、加熱器２１ａとしてシーズヒータが用いられる。シーズヒータは、電熱線が絶縁被膜で被覆された構造を有する。シーズヒータは、電熱線により任意の大きさの熱容量を得ることができる。加熱器２１ａを電解槽１１に接して設けることにより、電解槽１１を迅速に加熱することができる。なお、加熱器２１ａは、電解槽１１に接して設けられるが、電解槽１１と電気的には絶縁されている。 The electrolytic cell 11 includes a heater 21a and a blower 21b. In the present embodiment, a sheathed heater is used as the heater 21a. The sheathed heater has a structure in which a heating wire is covered with an insulating film. The sheathed heater can obtain a heat capacity of an arbitrary size with a heating wire. By providing the heater 21a in contact with the electrolytic cell 11, the electrolytic cell 11 can be heated quickly. The heater 21 a is provided in contact with the electrolytic cell 11, but is electrically insulated from the electrolytic cell 11.

まず、制御部２３は、加熱器２１ａをオンにする。それにより、電解槽１１の温度が上昇し、電解槽１１内の電解浴１２の温度も上昇する。電解浴１２が溶解するまでは、制御部２３は、温度センサ２２ａにより検出される温度に基づいて加熱器２１ａのオンおよびオフを制御する。電解浴１２が溶解するときの電解槽１１の温度（以下、電解槽温度下限値と呼ぶ。）は、予め測定されている。 First, the control unit 23 turns on the heater 21a. Thereby, the temperature of the electrolytic cell 11 rises, and the temperature of the electrolytic bath 12 in the electrolytic cell 11 also rises. Until the electrolytic bath 12 is dissolved, the control unit 23 controls on and off of the heater 21a based on the temperature detected by the temperature sensor 22a. The temperature of the electrolytic cell 11 when the electrolytic bath 12 is dissolved (hereinafter referred to as the electrolytic cell temperature lower limit) is measured in advance.

制御部２３は、電解槽１１の過昇温を防止するために、温度センサ２２ａにより検出される温度が予め設定された上限値（以下、電解槽温度上限値と呼ぶ。）以上になると、加熱器２１ａをオフにする。 When the temperature detected by the temperature sensor 22a is equal to or higher than a preset upper limit value (hereinafter referred to as an electrolytic cell temperature upper limit value), the control unit 23 is heated to prevent an excessive temperature rise in the electrolytic cell 11. to turn off the vessel 21a.

次に、制御部２３は、温度センサ２２ｂにより検出された電解浴１２の温度が加熱開始温度まで低下したか否かを判定する（ステップＳ４）。電解浴１２の温度が加熱開始温度まで低下していない場合には、制御部２３は電解浴１２の温度が加熱開始温度になるまで待機する。電解浴１２の温度が加熱開始温度まで低下した場合には、制御部２３は加熱器２１ａをオンにし（ステップＳ５）、送風機２１ｂをオフにして（ステップＳ６）、ステップＳ１の処理に戻る。 Next, the controller 23 determines whether or not the temperature of the electrolytic bath 12 detected by the temperature sensor 22b has decreased to the heating start temperature (step S4). If the temperature of the electrolytic bath 12 has not decreased to the heating start temperature, the control unit 23 waits until the temperature of the electrolytic bath 12 reaches the heating start temperature. When the temperature of the electrolytic bath 12 is lowered to the heating start temperature, the control unit 23 turns on the heater 21a (step S5), and turn off the blower 21b (step S6), and the process returns to step S1.
