Zusammenfassung:To solve the problem that metal precipitated by electrolysis contains strong acid, and is not easily treated.SOLUTION: A device for cleaning a metal recovery device, which is a cleaning device provided below a storage tank of a metal recovery device that has a filter for electrolyzing a solution containing metal existing in an ionic state and thereby recovering the metal and is provided, includes a recovery device for recovering cleaning water below the filter, a spray nozzle for spraying the cleaning water to the storage tank, return piping for returning the cleaning water in the recovery device back to the spray nozzle, a circulation pump provided on the return pipe, a pH meter provided on the return piping, and a controller for stopping supply of the cleaning water when the pH of the cleaning water flowing in the return piping by the pH meter becomes a prescribed value, and neutralizes the pH of the recovered metal.SELECTED DRAWING: Figure 1 【課題】電気分解によって析出する金属は強酸を含んでおりそのままでは取り扱いが容易でなかった。【解決手段】イオン状態で存在する金属を含有する溶液を電気分解することで前記金属を回収するフィルタを有する金属回収装置の貯留槽の下方に設けられる洗浄装置であって、前記フィルタの下方で洗浄水を回収する回収器と、前記貯留槽に前記洗浄水を散布する散布ノズルと、前記回収器中の前記洗浄水を前記散布ノズルに戻す戻り配管と、前記戻り配管に設けられた循環ポンプと、前記戻り配管に設けられたpH計と、前記pH計による前記戻り配管中を流れる前記洗浄水のpHが所定値になったら前記洗浄水の供給を停止する制御器を有する金属回収装置の洗浄装置は回収された金属のpHを中和する。【選択図】図1
