Abstract

PROBLEM TO BE SOLVED: To provide a method for stripping off an electrodeposited metal where a gap-forming step, a spreading step, and a separation step can be performed by one stripping apparatus, conveying equipment for conveying a cathode plate between apparatuses is not required, the downsizing of the apparatus is possible, a time for replacing (transferring) the cathode plate or the like is not required, working efficiency and productivity are favorable, and also cost reduction is possible.SOLUTION: After one wedge member 24 is inserted into a gap which is formed at one upper joining part between one surface of a cathode plate 1 and one electrodeposited metal 8 by pressing the one surface of the cathode plate 1 in the generally vertical direction using one flexing member 20, the other wedge member is inserted into a gap which is formed at the upper joining part by pressing the other surface of the cathode plate in the generally vertical direction using the other flexing member. By moving one pair of wedge members downward, the electrodeposited metal, i.e. a pair of two electrodeposited metals, is stripped off from the cathode plate without separating the pair while being spread in a V shape.

Description

  The present invention relates to an electrodeposited metal stripping apparatus capable of efficiently performing an operation of stripping an electrodeposited metal electrodeposited on a cathode plate from the cathode plate in electrolytic refining of metal, for example, copper electrolytic refining, and The present invention relates to a method for stripping an electrodeposited metal.

  2. Description of the Related Art Conventionally, a permanent cathode (PC) method has been widely used as an electrolytic process in metal electrolytic refining, for example, copper electrolytic refining. In this permanent cathode method, a stainless steel plate is used as a cathode (cathode) and crude copper is used as an anode (anode). It is a method of peeling off the attached copper to make a product.

  In the permanent cathode method, electrolysis is usually carried out continuously for 1 to 2 weeks. Then, the copper is lifted from the electrolytic cell in a state where the weight of the copper is about 50 to 90 kg, and the electrodeposited copper is peeled off from the stainless steel plate to obtain electrolytic copper. The stainless steel plate from which the electrodeposited copper is peeled is repeatedly used as the cathode plate. An example of such a permanent cathode method is disclosed in Patent Document 1 (Japanese Patent Laid-Open No. 2005-240146).

  Here, among processes that have been put into practical use as the permanent cathode method, there is a method called an ISA method. In the ISA method, both sides of the cathode plate are insulated and masked with vinyl chloride and the like, and the lower portion is masked so that the electrodeposition does not reach both sides and the lower portion. In this method, copper is peeled off by a peeling machine, whereby two pieces of electrolytic copper are obtained from one cathode plate.

Recently, for example, as disclosed in Patent Document 2 (Japanese Patent Publication No. 2003-502512), in the ISA method, the lower part of the cathode is not masked, and instead, the V groove is formed in the lower part of the cathode plate. A method has also been proposed in which when the copper electrodeposited on both sides of the cathode plate is peeled off, it can be easily separated.
In such conventional electrolytic refining of metal, a cathode plate 100 having a structure as shown in FIG. 25 is used.

  That is, a hanger bar 102 which is a horizontal support member, a plate-like electrode plate body 104 attached so as to hang downward from the hanger bar 102 in the vertical direction, and an insulating mask 106 are provided. In addition, a V-shaped groove (not shown) is formed on the lower end surface of the electrode plate body 104.

In this case, for example, in the case of copper refining, the electrode plate body 104 of the cathode plate 100 is made of stainless steel.
By the way, as the electrodeposition metal stripping device for stripping and separating the electrodeposited metal electrodeposited on the cathode plate 100 from the cathode plate 100, there are conventionally two types of so-called “separate type” and “envelope type”. An electrodeposition metal stripping apparatus has been proposed.

The above-described “separate type” electrodeposited metal stripping apparatus has a configuration as shown in FIGS.
As described above, the cathode plate 100 in which the electrodeposited metal 108 is electrodeposited on the electrode plate main body 104 is subjected to a gap forming step in the flexure apparatus.

  That is, as shown in FIG. 26, both surfaces of the cathode plate 100 fixed by the upper fixing members 110a and 110b and the lower fixing members 111a and 111b are alternately pressed in the vertical direction by the flexing members 112a and 112b. The cathode plate 100 is bent into a bow shape (flexing), and a gap is formed in the upper joint portion 103 between the cathode plate 100 and the electrodeposited metal 108.

  Such flexing is repeated several times as necessary until a sufficient gap is formed in the upper joint portion 103 in a stripping process described later until the wedge members 114a and 114b are inserted. It has become.

  That is, as shown in FIG. 26, one side of the cathode plate 100 fixed by the upper fixing members 110a and 110b and the lower fixing members 111a and 111b is pressed by the flexure member 112a in the direction of arrow A in the figure. The cathode plate 100 is bent into a bow shape, and a gap b is formed in the upper joint portion 103 between the cathode plate 100 and the electrodeposited metal 108b electrodeposited on the other surface side of the cathode plate 100.

  In addition, as shown in FIG. 27, the other surface side of the cathode plate 100 fixed by the upper fixing members 110a and 110b and the lower fixing members 111a and 111b is pressed by the arrow 112b in the direction of arrow B in the drawing, 100 is bent into a bow shape, and a gap a is formed in the upper joint portion 103 between the cathode plate 100 and the electrodeposited metal 108a electrodeposited on one side of the cathode plate 100.

  Thus, in the gap forming step, the cathode plate 100 in which the gaps a and b are formed in the upper joint portion 103 between the cathode plate 100 and the electrodeposited metal 108 electrodeposited on the surface of the cathode plate 100 is as follows. To the stripping device.

  In the stripping device, first, in the expanding step, as shown in FIG. 28, the lower portion of the cathode plate 100 is formed in the gap forming step while being fixed with the lower fixing members 111a and 111b sandwiched therebetween. The wedge members 114a and 114b are inserted into the gaps a and b from above, respectively.

  29, the wedge members 114a and 114b are moved downward along the cathode plate 100 as they are, so that the electrodeposited metal 108 electrodeposited on both surfaces of the cathode plate 100 is removed. The cathode plate 100 is expanded and peeled off from the cathode plate 100.

The expanded electrodeposited metals 108a and 108b remain in an integrated state at their lower ends and are substantially V-shaped in cross-sectional view.
Then, in the separation step, as shown in FIG. 30, two pairs of electrodeposited metals 108a and 108b, which are substantially V-shaped in cross-sectional view, are paired with a pair of clamp members 116, respectively. After gripping the metals 108a and 108b, as shown by the arrow D, the pair of clamp members 116 are moved in the diameter increasing direction to further expand the diameter of the two pairs of electrodeposited metals 108a and 108b to the horizontal position. It is supposed to let you.

  Thereafter, as indicated by an arrow E in FIG. 31, the clamp member 116 is moved away from each other to be separated from the cathode plate so as to obtain two separated electrodeposited metals 108a and 108b. It is configured.

  On the other hand, as the “envelope type” electrodeposited metal stripping device, there has been proposed a stripping device as disclosed in Patent Document 3 (Japanese Patent No. 4625028).

The electrodeposition metal stripping device of Patent Document 3 is configured such that a gap forming step and an expanding and separating step are performed in one stripping device.
That is, in the electrodeposition metal stripping apparatus disclosed in Patent Document 3, electrodeposition is performed on the surfaces of the cathode plate 100 and the cathode plate 100 in the same manner as the gap forming step in the above-described “separate type” electrodeposition metal stripping apparatus. Gaps a and b are formed in the upper joint 103 between the electrodeposited metals 108.

  Then, as shown in FIG. 32, gaps a and b formed in the upper joint portion 103 between the cathode plate 100 and the electrodeposited metal 108 electrodeposited on the surface of the cathode plate 100 are laterally formed. The saddle-shaped peeling member 118 is inserted, and the electrodeposited metal 108 electrodeposited on both sides of the cathode plate 100 is expanded and peeled off from the cathode plate 100.

The expanded electrodeposited metals 108a and 108b remain in an integrated state at their lower ends and are substantially V-shaped in cross-sectional view.
The electrodeposited metals 108a and 108b peeled off from the cathode plate 100 are pressed from both sides by using a pressing device (not shown), and are electrodeposited products. Shipped as a metal plate.

  By the way, in the conventional “separate type” electrodeposited metal stripping apparatus, the gap forming process, the expanding process, and the separating process are performed in separate apparatuses, so the cathode plate 100 is transported between the apparatuses. A transfer device is required, and the device becomes large, and it takes time for transfer (transfer) of the cathode plate 100, the work efficiency is poor, and the productivity is reduced. Cost will be high.

On the other hand, the “envelope type” electrodeposited metal stripping device of Patent Document 3 is configured such that a gap forming step and an expanding and separating step are performed in one stripping device.
However, a saddle-shaped peeling member 118 is formed in the gaps a and b formed in the upper joint 103 between the cathode plate 100 and the electrodeposited metal 108 electrodeposited on the surface of the cathode plate 100 from the side. Since a device to be inserted is separately required, the device configuration becomes complicated and the device becomes large.

Then, the wedge member 24b is further inserted into the gap b, and as shown in FIG. 8, the wedge member 24b is inserted until it reaches a vertical state.
In this state, as shown in FIG. 8, a slight gap S is opened between the wedge member 24b and the electrode plate body 4 of the cathode plate 1, and the wedge member 24b is removed in a stripping step described later. It is desirable to prevent the electrode plate body 4 from being damaged by the wedge member 24b when the angle is lowered.

  Similarly, as shown by an arrow E in FIG. 9, this time, the driving cylinder 20d of the flexing device 20 arranged on the left side is operated, and the flexing member 20b is moved in the direction of the electrode plate body 4 of the cathode plate 1. The cathode plate 1 is bent into a bow shape (flexing) by moving to the forward position, and a gap a is formed in the electrode plate body 4 of the cathode plate 1 and the upper joint portion 3 of the electrodeposited metal 8.

  In this state, as shown in FIG. 9, the drive cylinder 21a of the wedge insertion device 22 arranged on the right side is operated, and in the direction indicated by the arrow C in FIG. Rotate.

  11, the wedge members 24a and 24b of the wedge insertion device 22 are respectively connected to the guide member 25 shown in FIG. 1 and the drive provided above the frame base 12 (not shown). A pair of wedge members 24a and 24b are moved downward along the cathode plate 1 by a driving mechanism such as a motor or a hydraulic cylinder, as indicated by an arrow F in FIG.

Thereby, the electrodeposited metal 8 electrodeposited on both surfaces of the electrode plate body 4 of the cathode plate 1 is expanded.
Further, by further moving the pair of wedge members 24a and 24b downward, as shown in FIG. 15, the pair of electrodeposited metals 8 (8a and 8b) is expanded into a V shape without being separated. Peel from the cathode plate in the open state.

That is, the expanded electrodeposited metal 8 remains in an integrated state with the V-shaped tip 8c at the lower end thereof, and is substantially V-shaped in cross-sectional view.
The wedge members 24a and 24b move upward after the electrodeposited metal 8 is peeled off from the cathode plate 1 and return to their original positions.

  Then, as shown in FIG. 12, the wedge members 24a and 24b are inserted and moved downward, and are completely peeled off from the cathode plate 1 while being expanded in a V shape. The pair of dropped electrodeposited metals 8 (8a, 8b) is subjected to a positioning step in which the intermediate receiving device 26 receives the lower portion and aligns the center of the V-shaped tip 8c.

  That is, as shown in FIG. 3, the intermediate receiving device 26 is configured so that the comb-shaped intermediate receiving members 26 a and 26 b are in the alternate positions in the comb-tooth state.

The electrodeposition metal 8 (8a, 8b) is dropped by opening the intermediate receiving device 26 and passing between the crimping devices 30 composed of a pair of pinch rolls 28a, 28b. The metal plate 5 can be used.

  Therefore, no separate pressing device is required, and it is possible to make an electrodeposited metal plate that is a product that is easily overlaid, and transfer of the electrodeposited metal stripped away from the cathode plate. Time such as (transfer) is unnecessary, work efficiency and productivity are good, and cost can be reduced.
