Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for vertically suspending a seed plate used in wet copper electrolysis.

[0002]

2. Description of the Related Art FIG. 2 is a diagram showing a typical cathode electrode for a typical wet copper electrolysis. In the figure, 1 is a copper seed plate of a cathode for wet copper electrolysis, 2 is a hanging ribbon of a copper seed plate, 3
Is a metal cross beam that supports the seed plate via the hanging ribbon 2. In the wet electrolysis of copper, the thickness is 0.6 to
1.0 mm, width x height 800 mm x 800 mm ~ 1
A copper seed plate 1 serving as a cathode having a size of 200 mm × 1200 mm and a copper hanging hand ribbon 2 serving as a hanging hand and a current-carrying path for the cathode seed plate 1 in an electrolytic cell are manufactured independently, and a method such as electric welding is used. To electrically and mechanically connect both. The cathode seed plate 1 is a cross beam 3 installed between the hanging ribbons 2 folded as shown in FIG.
It is suspended in the electrolytic cell by means of and is energized via the cross beam. At this time, the anode is also installed in the electrolytic cell at the same time, and the copper component of the anode is refined into the cathode by the DC electric field.

Here, the total length of the hanging ribbon 2 refers to the length before being bent, and the length becomes half or less of the total length by bending.

[0004]

In the process of joining a copper seed plate serving as a cathode and a copper lifting ribbon, for example, a metal cross beam for energizing a path and supporting the seed plate is attached to the copper lifting ribbon. As shown in FIG. 3, the hanging ribbon 2 is folded in two from the central portion. However,
When the hanging ribbon is not bent evenly with respect to the cross beam, the copper seed plate 1 hung as shown in FIG. Not only is it difficult to install dozens of plates in an electrolytic cell, but there is a case in which electrolysis is impossible due to an electrical short circuit caused by contact with the anode in the electrolytic cell. For this reason, it is necessary to preliminarily widen the anode-cathode distance in the tank in consideration of the inclination of the copper seed plate. In other words, the packing density of each electrode in the electrolytic cell and the product production capacity are
It is significantly limited by widening this interval.

An object of the present invention is to improve a conventional method for suspending a seed plate for wet copper electrolysis, to prevent a short circuit accident due to contact between an anode and a cathode and to fill each electrode in an electrolytic cell. It is an object of the present invention to provide a method of vertically suspending a wet copper electrolytic seed plate capable of improving the density, that is, improving the production capacity of products.

[Means for Solving the Problems] In order to solve the above problems, it is important to consider how to vertically hang a copper seed plate. Therefore, the present inventor has focused on the rigidity of the hanging ribbon and investigated the influence on the verticality of the seed plate by using the hanging ribbons of various weights and dimensions. It was found that the copper seed plate can be hung vertically when used, and the present invention has been completed.
That is, the present invention has a thickness of 0.6 to 1.0 mm and a width x height of 800 mm x 800 mm to 1200 mm x 12
In a method of vertically suspending a wet copper electrolytic seed plate having a dimension of 00 mm, a copper handle ribbon is used to have a weight of 0.75% or more of the seed plate weight so that the cathode seed plate can be vertically suspended by its own weight. Less than 3.8%, total length 320
600 mm or less for mm or more, 100 for width of 25 mm or more
The present invention is characterized by a method of vertically suspending a seed plate for wet copper electrolysis formed to have a size of mm or less.

2. The weight of the hanging hand ribbon is the weight of the copper seed plate.
Greater than 8% and the length of the hanging ribbon is 320 mm
If the width is less than 100 mm and the width exceeds 100 mm, the seed plate becomes difficult to be hung vertically as shown in FIG. 4, and it easily contacts with the anode in the electrolytic cell to cause an electrical short circuit. Is less than 0.75% of the weight of the seed plate, and the length of the hanging ribbon is longer than 600 mm and the width is less than 25 mm, the copper seed plate vibrates violently during suspension transportation of the seed plate to the electrolytic cell. Associated with work difficulties. In addition, the weight of the cathode during or after the electrolysis cannot withstand the weight of the cathode, and the hanging ribbon may be broken.

According to the present invention, even if the hanging ribbon is not bent evenly with respect to the cross beam, the hanging ribbon is bent by the weight of the copper seed plate and the verticality of the seed plate is maintained. Further, the strength without breaking the hanging ribbon can be obtained.

BEST MODE FOR CARRYING OUT THE INVENTION The seed plate for wet copper electrolysis, which is the subject of vertical hanging according to the present invention, has a thickness of 0.6 to 1.0 m.
m, width x height 800 mm x 800 mm to 1200 m
It has a size of m × 1200 mm. The copper seed plate hanging hand ribbon according to the present invention has a weight of 0.75% or more and 3.8% or less of the weight of the seed plate, and a hanging hand ribbon length of 320 mm or more and 600 mm. Less than,
Its width is 25 mm or more and 100 mm or less.

The hanging hand ribbon of the present invention will be described in more detail below. In the hanging hand ribbon of the present invention, the hanging hand ribbon is electrically applied to a seed plate for wet copper electrolysis by various methods.
Mechanically bonded. Then, it is suspended with the metal cross beam as a fulcrum. At this time, if the ribbon is not bent evenly with respect to the cross beam, the seed plate is not located directly below (vertically below) the cross beam, but the cross beam is inserted to transfer it to the electrolytic cell. Therefore, when lifted, the ribbon bends due to the weight of the seed plate, and the seed plate is supported vertically. Therefore, it is easy to install in the electrolytic cell, and the anode and the cathode can be arranged at a much narrower interval than in the conventional method, and as a result, the number of anodes / cathodes filled in the electrolytic cell can be increased.
