Description

本発明は、金属イオンを含有する廃液から、電解によって金属を回収する装置に関する。 The present invention relates to an apparatus for recovering a metal by electrolysis from a waste liquid containing metal ions.

貴金属やレアメタルなどの金属は世界的に生産量が少なく需要が逼迫しているところ、国内での生産が極めて乏しいため外国からの輸入に頼る必要があるが、外国の経済政策等により輸入量が制限されることもあり国内企業が入手するに際して政治リスクもあった。このため、工場等から排出される排水や廃液に含有されている金、銀、銅、ニッケル、白金族元素等の金属は、排水や廃液から回収されて再利用されている。 Metals such as precious metals and rare metals are produced in small quantities worldwide and demand is tight, but domestic production is extremely scarce, so it is necessary to rely on imports from foreign countries, but the import volume is high due to foreign economic policies, etc. There was also a political risk when domestic companies obtained it due to restrictions. For this reason, metals such as gold, silver, copper, nickel, and platinum group elements contained in wastewater and waste liquid discharged from factories and the like are recovered from the waste water and waste liquid and reused.

排水や廃液から金属を回収する装置は従前より知られているが、例えば特許文献１には、処理槽本体内に、モータによって軸を中心にして回転する円筒状の陰電極と、陰電極と対向するように配置された複数の板状陽電極とを備えている電解回収装置が開示されている。 A device for recovering metal from wastewater or waste liquid has been known for a long time. For example, in Patent Document 1, a cylindrical negative electrode that is rotated around an axis by a motor and a negative electrode are described in Patent Document 1. An electrolytic recovery device including a plurality of plate-shaped positive electrodes arranged so as to face each other is disclosed.

そして、特許文献２には、軸を中心として回転する柱状または筒状の回転陰電極と、回転陰電極と対向するように配置された陽電極と、網状または多孔質状の導電体等を備えている電解回収装置が開示されている。 Further, Patent Document 2 includes a columnar or tubular rotating negative electrode that rotates about an axis, a positive electrode arranged so as to face the rotating negative electrode, a net-like or porous conductor, and the like. The electrolytic recovery device is disclosed.

以下、本発明に係る電解回収装置に関する実施の形態について、添付の図面に基づいて詳しく説明する。なお、以下に説明する実施形態は、本発明を実施するに好ましい具体例であるから、技術的に種々の限定がなされているが、本発明は、以下の説明において特に発明を限定する旨が明記されていない限り、この形態に限定されるものではない。説明中の上下方向は、図１における上下方向を意味している。 Hereinafter, embodiments of the electrolytic recovery device according to the present invention will be described in detail with reference to the accompanying drawings. Since the embodiments described below are specific examples preferable for carrying out the present invention, various technical restrictions are made, but the present invention is intended to particularly limit the invention in the following description. Unless otherwise stated, it is not limited to this form. The vertical direction in the description means the vertical direction in FIG.

図１から図５に示すように、電解回収装置は、処理槽１、陰電極２、係止部３、支持部４、陽電極５、導電部材６、電動モータ７、蓋部８などから構成され、処理槽１内の位置する電動モータ７により回転軸２１を中心に回転する円筒形の陰電極２と、陰電極２の外側には複数の陽電極５が配設されている。 As shown in FIGS. 1 to 5, the electrolytic recovery device includes a processing tank 1, a negative electrode 2, a locking portion 3, a support portion 4, a positive electrode 5, a conductive member 6, an electric motor 7, a lid portion 8, and the like. A cylindrical negative electrode 2 that is rotated around a rotating shaft 21 by an electric motor 7 located in the processing tank 1 and a plurality of positive electrodes 5 are arranged outside the negative electrode 2.

処理槽１は、金属が溶解している廃液を収容する部材である。本実施形態において、処理槽１は廃液を収容するとともに、廃液の下方に位置している電動モータ７、操作パネルと接続された制御部なども収容する筐体としても機能しているが、他の実施形態において、必ずしも筐体を兼ねている必要はなく、筐体とは独立して設けられていても良い。 The treatment tank 1 is a member that houses a waste liquid in which a metal is dissolved. In the present embodiment, the treatment tank 1 functions as a housing for accommodating the waste liquid and also for accommodating the electric motor 7 located below the waste liquid, the control unit connected to the operation panel, and the like. In the embodiment of the above, it is not always necessary to also serve as a housing, and the housing may be provided independently of the housing.

処理槽１の少なくとも上部は、本実施形態のような角筒状又は丸筒状などの筒状に上方に向かって開口して形成されていることが好ましい。処理槽１の上部がこのような形状に形成されていると、陽電極５が固設された支持部４を取り出すときに、処理槽１に引っかかることなくスムーズに取り外し又は取り付けることができる。 It is preferable that at least the upper portion of the treatment tank 1 is formed by opening upward in a tubular shape such as a square tubular shape or a round tubular shape as in the present embodiment. When the upper portion of the treatment tank 1 is formed in such a shape, when the support portion 4 on which the positive electrode 5 is fixed is taken out, it can be smoothly removed or attached without being caught in the treatment tank 1.

陰電極２は、処理槽１の内部に位置している電極である。陰電極２は、円筒形状を有しており、その内部の軸中心に沿って配設された回転軸２１及び回転軸２１を回転させる電動モータ７によって所定の速度で回転可能である。陰電極２は、図示しない給電部から回転軸２１内を通じて通電されることにより、その表面に廃液に含有されている所望の金属を析出させることができる。このようにして、陰電極２に金属が析出されると、装置を停止してから陰電極２を処理槽１から取り外して、陰電極２に付着した析出された金属をそぎ落とすなどして回収する。 The negative electrode 2 is an electrode located inside the treatment tank 1. The negative electrode 2 has a cylindrical shape, and can be rotated at a predetermined speed by a rotating shaft 21 and an electric motor 7 for rotating the rotating shaft 21 arranged along the axis center inside the negative electrode 2. The negative electrode 2 can deposit a desired metal contained in the waste liquid on the surface of the negative electrode 2 by being energized from a feeding portion (not shown) through the rotating shaft 21. When metal is deposited on the negative electrode 2 in this way, the device is stopped, the negative electrode 2 is removed from the processing tank 1, and the deposited metal adhering to the negative electrode 2 is scraped off to recover the metal. To do.

そして、陰電極２は、実際の使用時には回転されることから、単純な円筒形でなく、廃液の流れを制御するために、中心軸方向に沿って円筒形の外周面又は内周面に複数の板部材等が突設されていてもよい。さらに、陰電極２は、本実施形態において、板状部材を円筒形に形成した形状を有しているが、他の実施形態において、網状の部材を同様に円筒形状とすることもできる。 Since the negative electrode 2 is rotated during actual use, it is not a simple cylindrical shape, but a plurality of negative electrodes 2 are formed on the outer peripheral surface or the inner peripheral surface of the cylindrical shape along the central axis direction in order to control the flow of waste liquid. The plate member or the like may be provided so as to project. Further, the negative electrode 2 has a shape in which a plate-shaped member is formed in a cylindrical shape in the present embodiment, but in another embodiment, the net-like member can be similarly formed in a cylindrical shape.

また、陰電極２は、導電体であるが、廃液に浸漬されるために、廃液に対して耐腐食性を有するステンレス鋼、チタンなどから形成されることが好ましい。 Further, although the negative electrode 2 is a conductor, it is preferably formed of stainless steel, titanium, or the like having corrosion resistance against the waste liquid because it is immersed in the waste liquid.

係止部３は、処理槽１の内面に固設された部材であり、支持部４を係止する。係止部３は、支持部４と係止する窪み３１が形成されており、本実施形態において窪み３１は、上方に開口している溝状である。窪み３１が、上方に開口している溝状であることによって、処理槽１の上部が角筒状であることから処理槽１に載置している蓋部８を取り外し、窪み３１に挿嵌している支持部４を係止部３から上方に持ち上げて、図５に示すように、支持部４に固設された陽電極５を装置から簡便に取り外すことができる。さらに、装置外で陽電極５を取り替えることができるので、処理槽１内に陽電極５を固設する螺子等の固定手段を廃液中に落下させるおそれもなく、円滑に交換作業を実施することができる。そして、陽電極５を取り替えた支持部４を、再び窪み３１に挿嵌させて係止することで、処理槽１に簡便に取り付けることができる。本実施形態において、係止部３の窪み３１は上方に開口している溝状であるが、他の実施形態において、係止部３の窪みが、支持部４を取り外し及び取り付け容易に変形自在な弾性部材等からなり、側方に開口していたり、廃液中に落下しない限りにおいて下方に開口していたりしてもよい。 The locking portion 3 is a member fixed to the inner surface of the processing tank 1 and locks the supporting portion 4. The locking portion 3 is formed with a recess 31 that locks with the support portion 4, and in the present embodiment, the recess 31 has a groove shape that opens upward. Since the recess 31 has a groove shape that opens upward, the upper part of the treatment tank 1 has a square tubular shape. Therefore, the lid portion 8 placed on the treatment tank 1 is removed and inserted into the recess 31. The supporting portion 4 is lifted upward from the locking portion 3, and as shown in FIG. 5, the positive electrode 5 fixed to the supporting portion 4 can be easily removed from the device. Further, since the positive electrode 5 can be replaced outside the apparatus, there is no risk of dropping a fixing means such as a screw for fixing the positive electrode 5 in the processing tank 1 into the waste liquid, and the replacement work can be smoothly performed. Can be done. Then, the support portion 4 in which the positive electrode 5 has been replaced is inserted into the recess 31 again and locked, so that the support portion 4 can be easily attached to the processing tank 1. In the present embodiment, the recess 31 of the locking portion 3 has a groove shape that opens upward, but in other embodiments, the recess of the locking portion 3 is deformable so that the support portion 4 can be easily removed and attached. It may be made of an elastic member or the like and may be opened to the side or may be opened downward as long as it does not fall into the waste liquid.

そして、本実施形態において、係止部３の窪み３１は溝状であるが、他の実施形態において、係止部３の窪み３１は丸穴、角穴、長孔など、支持部４にそれらと挿嵌する突起と対応するように設けて、係止部３と支持部４を係止するようにすることができる。さらに、係止部３は、本実施形態における溝状や上記変形例の丸穴、角穴、長孔などの雌部材ではなく、突起や突設部材などの雄部材として、支持部４にそれらと挿嵌する凹部、丸穴、角穴、長孔などの雌部材を設けて、係止部３と支持部４を係止するようにすることができる。 In the present embodiment, the recess 31 of the locking portion 3 is groove-shaped, but in other embodiments, the recess 31 of the locking portion 3 is formed in the support portion 4 such as a round hole, a square hole, or an elongated hole. It is possible to provide the locking portion 3 and the supporting portion 4 so as to be provided so as to correspond to the protrusion to be inserted. Further, the locking portion 3 is not a female member such as a groove-shaped hole or a round hole, a square hole, or an elongated hole in the above-described modification in the present embodiment, but is a male member such as a protrusion or a projecting member, and is attached to the support portion 4. A female member such as a recess, a round hole, a square hole, or an elongated hole to be inserted can be provided to lock the locking portion 3 and the supporting portion 4.

係止部３は、支持部４が通電する導電体であるときに通電し不必要な電流が流れることを防ぐために、絶縁体であることが好ましい。具体的に、係止部３は、ポリ塩化ビニル、ポリエチレン、天然ゴム、ポリエステル、エポキシ樹脂、メラミン樹脂、フェノール樹脂、ポリウレタン、ガラス繊維などの有機材料又は無機材料から成ることが好ましい。また、係止部３は、本実施形態において、処理槽１の各々の内面に２個ずつ合計８個設けられているが、他の実施形態において、処理槽１の各々の内面に１個ずつまたは３個ずつ以上としたり、実施形態の係止部３よりも長くして１個ずつとしたりすることもできる。 The locking portion 3 is preferably an insulator in order to prevent an unnecessary current from flowing when the support portion 4 is a conductor that is energized. Specifically, the locking portion 3 is preferably made of an organic material or an inorganic material such as polyvinyl chloride, polyethylene, natural rubber, polyester, epoxy resin, melamine resin, phenol resin, polyurethane, and glass fiber. Further, in the present embodiment, two locking portions 3 are provided on each inner surface of the processing tank 1, for a total of eight, but in other embodiments, one is provided on each inner surface of the processing tank 1. Alternatively, the number may be three or more, or one may be longer than the locking portion 3 of the embodiment.

また、係止部３には、窪み３１を形成する側面が傾斜している傾斜面３２を有している。傾斜面３２は、窪み３１の開口側に向かって広くなるように上下方向より所定の角度だけ傾斜されている。これにより、陽電極５を取り替えた支持部４を取り付けるときに、支持部４を窪み３１の開口の上方のおおよその位置に配設することで、支持部４が傾斜面３２に案内され窪み３１に挿嵌する。 Further, the locking portion 3 has an inclined surface 32 whose side surface forming the recess 31 is inclined. The inclined surface 32 is inclined by a predetermined angle from the vertical direction so as to widen toward the opening side of the recess 31. As a result, when the support portion 4 in which the positive electrode 5 is replaced is attached, the support portion 4 is arranged at an approximate position above the opening of the recess 31, so that the support portion 4 is guided to the inclined surface 32 and the recess 31 is provided. Insert into.

支持部４は、係止部３と着脱可能に係止し、陽電極５が固設される部材である。支持部４は、係止部３と着脱可能に係止することにより、陽電極５を処理槽１からの取り外し及び取り付けを簡便なものとし、陽電極５の取替え作業を容易にしている。支持部４は、本実施形態において、板状であるが、他の実施形態において、係止部３と着脱可能であり陽電極５を固設できる限りにおいて、角柱状、丸棒状、先端が曲がったフック状などの形状としてもよく、さらに、係止部３の形状に応じて突起や突設部材などの雄部材又は凹部、丸穴、角穴、長孔などの雌部材を設けることができる。また、支持部４は、本実施形態において、処理槽１の内周側面に亘り環状に形成されているが、他の実施形態において、処理槽１の内面ごとに独立していてもよい。 The support portion 4 is a member that is detachably engaged with the locking portion 3 and the positive electrode 5 is fixedly attached. The support portion 4 is detachably locked with the locking portion 3 to facilitate the removal and attachment of the positive electrode 5 from the processing tank 1 and facilitate the replacement work of the positive electrode 5. The support portion 4 has a plate shape in the present embodiment, but in other embodiments, the support portion 4 has a prismatic shape, a round bar shape, and a bent tip as long as it can be attached to and detached from the locking portion 3 and the positive electrode 5 can be fixed. The shape may be a hook shape or the like, and further, a male member such as a protrusion or a projecting member or a female member such as a recess, a round hole, a square hole, or an elongated hole can be provided depending on the shape of the locking portion 3. .. Further, in the present embodiment, the support portion 4 is formed in an annular shape over the inner peripheral side surface of the treatment tank 1, but in other embodiments, the support portion 4 may be independent for each inner surface of the treatment tank 1.

支持部４は、一の部材又は複数の部材からなる導電体により形成されており、処理槽１の内周側面に亘り環状に形成されていることが好ましい。このように形成することにより、図２から図５に示すように、導電部材６を介して支持部４の一部に図示しない給電部から通電することにより、複数の陽電極５に通電することが可能となり、配線の取り回しが単純化できるので、故障しにくい耐久性の高い装置を製作することができる。 The support portion 4 is preferably formed of a conductor composed of one member or a plurality of members, and is preferably formed in an annular shape over the inner peripheral side surface of the processing tank 1. By forming in this way, as shown in FIGS. 2 to 5, a plurality of positive electrodes 5 are energized by energizing a part of the support portion 4 from a feeding portion (not shown) via the conductive member 6. This makes it possible to simplify the wiring arrangement, so it is possible to manufacture a highly durable device that is less likely to break down.

陽電極５は、支持部４に固設された電極であり、陰電極２の対電極である。陽電極５は、図示しない給電部より導線を通じて支持部４を解して間接的に又は直接的に通電され、陰電極２との間で廃液中に電流を流す。本実施形態において、陽電極５は板状であるが、他の実施形態において、角柱状、丸棒状などの形状としてもよい。また、陽電極５は、本実施形態において、処理槽１の各々の内面に１枚ずつ合計４枚設けられているが、他の実施形態において、処理槽１の各々の内面に１枚ずつまたは３枚ずつ以上としたりすることもできる。 The positive electrode 5 is an electrode fixed to the support portion 4 and is a counter electrode of the negative electrode 2. The positive electrode 5 is indirectly or directly energized by disconnecting the support portion 4 from a feeding portion (not shown) through a conducting wire, and a current is passed through the waste liquid between the positive electrode 5 and the negative electrode 2. In the present embodiment, the positive electrode 5 has a plate shape, but in other embodiments, it may have a prismatic shape, a round bar shape, or the like. Further, in the present embodiment, one positive electrode 5 is provided on each inner surface of the treatment tank 1, for a total of four positive electrodes 5, but in other embodiments, one positive electrode 5 is provided on each inner surface of the treatment tank 1.

In the present embodiment, the conductive member 6 sandwiches the support portion 4 together with the positive electrode 5 at the tip portion thereof and is fixed by a screw. Further, when the base end portion of the conductive member 6 is attached to the device, when the anode side cover C of the device is removed and the base end portion of the conductive member 6 is removed from the device, the positive electrode 5 is as shown in FIG. And the support portion 4 can be removed without disassembling.

嵌合部９は、処理槽１の液底板Ｂに固設された部材であり、陽電極５を嵌合する。嵌合部９は、陽電極５の下端と嵌合する窪み９１が形成されており、本実施形態において窪み９１は、上方に開口している溝状である。窪み９１が、上方に開口している溝状であることによって、陽電極５の下端を嵌合し、陽電極５が簡便に固定することができる。また、嵌合部９には、窪み９１を形成する側面が傾斜している傾斜面９２を有している。傾斜面９２は、窪み９１の開口側に向かって広くなるように上下方向より所定の角度だけ傾斜されている。これにより、陽電極５を取り替えた支持部４を取り付けるときに、陽電極５を窪み９１の開口の上方のおおよその位置に配設することで、陽電極５が傾斜面９２に案内され窪み９１に嵌合する。 The fitting portion 9 is a member fixed to the liquid bottom plate B of the processing tank 1 and fits the positive electrode 5. The fitting portion 9 is formed with a recess 91 that fits with the lower end of the positive electrode 5, and in the present embodiment, the recess 91 has a groove shape that opens upward. Since the recess 91 has a groove shape that opens upward, the lower end of the positive electrode 5 can be fitted and the positive electrode 5 can be easily fixed. Further, the fitting portion 9 has an inclined surface 92 whose side surface forming the recess 91 is inclined. The inclined surface 92 is inclined by a predetermined angle from the vertical direction so as to widen toward the opening side of the recess 91. As a result, when the support portion 4 in which the positive electrode 5 is replaced is attached, the positive electrode 5 is arranged at an approximate position above the opening of the recess 91, so that the positive electrode 5 is guided to the inclined surface 92 and the recess 91 is provided. Fit into.
