Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a plate making apparatus for a cathode seed plate used for electrolytic refining, and in particular, plate making so that the distance between the cathode supporting rod and the upper side end of the cathode seed plate is kept constant and parallel to each other. The present invention relates to a plate making apparatus.
[0002]
[Prior art]
First, an outline of the electrolytic refining equipment will be described (see FIG. 7). The electrolytic cell 30 is a rectangular parallelepiped cell opened upward, and a common conductor 32 (bus bar) is installed on the upper surface of the long side wall 30c. As best shown in FIG. 6, a plurality of electrolytic cells 30 are installed adjacent to each other in the vertical and horizontal directions, and the total number of the electrolytic cells reaches several hundreds. In the electrolytic solution of each electrolytic cell 30, a plurality of (typically about 20 to 50 in the case of Cu) cathode seed plates (cathode plates) K and anode-eard types (anode plates) A are alternately parallel. So as to be immersed. Each cathode plate K is suspended from a cathode support bar (cross bar) 34. Both ends of the cathode support rod 34 and the ears of the anode plate A are supported by the common conductor 32 provided on the upper surface of the left or right electrolytic cell side wall 30c and the other electrolytic cell side wall 30c, respectively.
[0003]
In the Walker-type current supply method shown in FIG. 6, wiring is performed so that current flows from all anode plates A to all cathode plates K of each electrolytic cell 30 by making a total of four electrolytic cells 30 in a vertical and horizontal pair. ing. As a power source for electrolytic refining, a thyristor type or diode type semiconductor rectifier is used because it requires a low voltage and a large current and can adjust the voltage in a wide range according to the conditions of electrolytic operation while having a large capacity. .
[0004]
Then, the metal (Cu) eluted from the anode plate A into the electrolytic solution is deposited on the cathode plate K, and gradually increases in thickness and weight, and finally becomes a high-purity product.
[0005]
In connection with the cathode supporting rod 34 by the ribbon 35 of the cathode plate K used for such electrolytic refining, conventionally, the relative mounting position of the cathode supporting rod 34 and the cathode plate K has been particularly considered. There wasn't.
[0006]
[Problems to be solved by the invention]
However, when the cathode support rod 34 and the cathode plate K are fixed by the ribbon, the cathode plate K and the upper end of the cathode plate K are not fixed so that they are parallel to each other, when the cathode plate K is immersed in the electrolytic cell. The inconvenience that either the left or right upper end of the cathode plate K protrudes from the electrolyte surface and no metal (Cu) is deposited there. The same problem arises when the length between the cathode support rod 34 and the upper end of the cathode plate K is not constant and varies.
Further, there is a possibility that the anode plate A and the cathode plate K are misaligned, the current distribution varies, and the current efficiency is lowered.
Furthermore, if the cathode support rod 34 and the upper end of the cathode plate K are parallel and are not fixed in a balanced manner in the left and right direction, when the refining is completed and the weight of the cathode plate K increases, The weight balance applied to the ribbon 35 may be lost, and a high load may be applied to one of the ribbons 35. In the worst case, the ribbon may be severed.
[0007]
Therefore, the present invention keeps the distance between the cathode supporting plate and the upper side end of the cathode seed plate (cathode plate) constant, positions them so as to be parallel to each other, and balances the left and right while supporting the cathode. It is an object of the present invention to provide a cathode seed plate production apparatus in electrolytic refining capable of fixing a working basket and a cathode seed plate (cathode plate) with a ribbon.
[0008]
Another object of the present invention is to provide a cathode seed plate production apparatus in electrolytic refining capable of automatically and quickly fixing a cathode supporting rod and a cathode seed plate (cathode plate) with a ribbon. And
