Abstract

PURPOSE:To efficiently reform the sectional shape of an anode, by intermittently sequentially sending anodes being supported under a horizontal condition onto a surface table by a walking conveyer, and performing the reformation of bends at predetermined parts with a leveling bar. CONSTITUTION:Anodes A supported under a horizontal condition are intermittently carried one by one with a walking conveyer WC (WC3, WC4). When the anode A is carried onto a surface table 6 at a predetermined position, the walking conveyer WC is lowered to mound the anode A on the surface table 6. When the anode A is detected by anode detectors 2a, 2b, leveling bars 7a-7g are lowered at the same time to correct warps and twists at both ears E and other parts of the anode A. Thereafter, the leveling bars 7a-7g are raised with the retreat of the walking conveyer WC. The walking conveyer WC rises again and moves forwards by one stroke while supporting the reformed anode A. Hence, said anode A is sent to the next step, while a following anode is sent into the machine 3 for reforming bends.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an anode curve C'lfN correcting method and apparatus for correcting the cross-sectional shape of a metal anode for electrolysis.

In electrolytic refining of metals, it is required to make the distance l', 41 between the anode and cathode in the electrolytic cell as small as possible in order to improve the electrolytic capacity per unit floor area and reduce costs.

The crude copper, crude nickel, crude lead, crude tin, etc. obtained through smelting are cast into a rectangular plate shape with ears E and E extending to the left and right from a straight double-ended sword, as shown in Figure 1. Electrolysis is carried out by hanging J-Engine E and E on the edge of the electrolytic cell as soluble anode A. The anode A is most commonly cast using an open water XV mold, which is the easiest to manage, and automatically weighed molten metal is poured into the mold.

However, the anode A taken out from the mold was not necessarily flat, but had warps and twists, so a thin plate of refined metal was suspended vertically as a cathode in the electrolytic tank, and the anode was lined up next to it to create νj as described above. When an uncorrected anode A is hung in an electrolytic cell by hooks IJ and E, the eight adjacent anodes or the anode A and the anode come into contact, causing a short circuit and uneven dissolution of the anode A, resulting in electrolysis. This may lead to poor electrodeposition of the product, decrease in electrolytic power, and increase in castback rate.

Therefore, it is absolutely necessary to correct the cross-sectional shape of a cast, uncorrected anode when shaping the anode to efficiently remove warpage and twisting.

Therefore, as a result of various studies to solve this problem, the authors carried out the anode in a horizontally supported state, and during the transportation, they applied bending correction processing at multiple points on the main body, including both ears of the anode. We came to the conclusion that the cross-sectional shape of the anode can be corrected most efficiently using this method, and by pursuing this, we arrived at the present invention described below. Here, the anode surface correction or anode cross-sectional shape correction is a general term for correcting bending, warping, and twisting of the anode, or further adjusting the cross section so that it has a desired desired shape.

That is, an object of the present invention is to correct at least the twist of the anode between the receiving process of carrying in the metal anode for electrolysis and the carrying out process of carrying out the anode after shaping. Alternatively, the anode can be bent or straightened in order to further adjust the cross-sectional shape to the target shape.
In the positive method, the step of correcting the cross-sectional shape of the anode includes:
An object of the present invention is to provide a method and device for correcting curve 9 of an anode, which is characterized by applying bend correction processing to a plurality of points including both ears of the anode while holding the anode in a horizontally supported state.

The present invention will be explained below with reference to illustrated embodiments.

FIG. 2 is an explanatory diagram of an anode shaping system equipped with an anode curvature straightening device according to the present invention, and FIG. 3 is a plan view of the system, showing unstraightened metal produced at a milling factory. Anode A (for example, a copper anode) is usually transported to the receiving process S1 directly from a smelting factory or from an unformed anode stockyard with both ears of anode A suspended vertically and supported. There is. The anode A carried into this receiving step Sl is sequentially converted to a horizontally supported state in a reversing step S2, and is then transferred to the starting end WC of the walking conveyor WC for the next cross-sectional shape correction step S.
The anode A is placed on the side of the anode, pushed by the putu/ya P, and conveyed in a horizontally supported state by the walking conveyor WC. .

Next, the faults of the anode bending correction device 1 will be explained in detail. As shown in FIGS. 2 to 5, this bend straightening device 1 removes the anodes A when the electrolytic metal anodes 8, which are transported one by one in a horizontally supported state, reach a predetermined position. For example, the anode detection device 2 consists of a light emitter 2a and its light receiver 2b, and a detection signal is output by the light. When the anode A is positioned and held in a horizontally supported state, the anode A is pressed at multiple locations including both ears E and E to correct the warping and twisting of the anode A, and the anode after the bend correction is completed. The above-mentioned walking conveyor wc and -c large mb are constructed as an anode transfer device for sending A to the next process.

As shown in FIG. 6, the walking conveyor WC has left and right walls and a lower part supported by guide rollers W on a base B, and is rotated in the feeding direction of the anodes A by a feeding 9-direction operating cylinder 4. forward by a constant stroke d (FW
) and backward (k3W), and can also be moved up and down in the earthwork direction by means of a vertically operating cylinder 5.

As shown in FIGS. 2 and 3, the starting end -WC, of the walking conveyor Wc is located intersecting the slide mount C, 02 branched from the reversing process.

Next, the curve straightening machine 3 will be explained. As shown in FIGS. 4 to 8, the curve straightening machine 3 is conveyed by the walking conveyor wc and has a surface plate 6 on which the anode A is placed. It has a plurality of (seven in this embodiment) straightening bars 7a to 7g that apply a breath to the anode AK on the surface plate 6 to straighten a plurality of places including both ears of the anode A. .

As shown in FIGS. 4, 6, and 8, the surface plate 6 is divided into three parts: a center plate part 6a and left and right groove parts 6b, 6c. Between the section 6c is the walking conveyor W C' (7) Right conveyor section W
C3 is passed through, and the center board part 6a and left board part 6b
A walking conveyor WC (7) (left conveyor = V WC) is passed through ``jh''.

Further, the upper 6 self-correcting bars 7a, 7t) are used to correct both ears E, E of the anode as shown in FIG.
~7g are arranged so that the main body of the anode A can be evenly corrected.

However, as shown in Fig. 9, the walking conveyor W
In the raised position where C is operated in the vertical direction/the cylinder 5 is extended (support level L, -L, position in FIG. 9), the anode A is placed in a horizontal state on the support arrow WP on the walking conveyor wc, Also, the above Norinda 5 or the contracted bottom 1)
? At the f position (Fig. 9 support level L2 L2 position),
The surface plate 6 of the target straightening machine 3 and the receivers 8 and 9 provided at the front and back positions of the surface plate 6 are relatively positioned at a stomach level ft from the walking conveyor Wc, and act as a substitute for the walking conveyor. 7/- It is configured to receive the anode A, and the walking conveyor WC moves upward, forward (FYN), downward and backward (BW) so that the anode A can be sequentially sent to the surface plate 6 and positioned. It has become.

The removed anode A is subjected to the next single weight measurement process S4 and the thickness 6.
11j In the determination process S5, it is determined whether the unit weight or thickness is acceptable or not, and the anodes which are unacceptable in terms of unit weight or thickness are rejected as defective anodes AN by the puttyer P2 to the discharge process S6 of good anodes.

A good quality anode A with a single weight and thickness chorus.
G is branched into two lines by a pusher P3 on the slide mounts CI and C2, and is sent to the selvedge beams S7 and S7, which process and shape the lower part of the selvedge E of the anode AU, where the selvedge is processed. After that, they are assembled again and transported as shaped anodes from the discharge step S8 to an electrolysis factory or shaped anode stockyard.

Next, the operation of the above configuration will be explained with reference to FIG. 49. From the anode receiving step S,'ll]lI, the anodes A are placed one by one in a horizontal state on the support protrusion WP of the starting end WC4 of the walking conveyor WC. First, as shown in Figures 159 (5) to (13), the walking conveyor WC1fi support level L, L I shape '7

is lowered from the support levels L, -L to the support level L2-L2 and placed on the surface plate 6. Then, the anode detection device 2 detects its presence, and based on the anode detection signal sent from the anode detection device 2, the tee correction pars 7a to 7g simultaneously descend to the both ears of the anode A1.
, E and the main body are subjected to iii straightening processing to remove warpage and twisting and to form a straight anode. and the ninth
As shown in FIG.
is raised as shown in FIG. 9 (■), and the corrected anode A1 is moved forward (FW) with support levels L and -L as shown in FIG. 9 [F], The anode A1 reaches the single weight measuring step S4 and the thickness measuring step S5, and the next anode A2 reaches above the surface plate 6.

In this way, anode A2. Correcting processing can be continuously applied to A3 and later sheets in the same way.

At this time, the cyanode A can be reliably sent sequentially onto the surface plate 6 by the walking conveyor WC, which moves back and forth with a constant stroke d, so that the cyanode A can be accurately corrected to the preset correction position. Needless to say, you can hit pars 7a to 7g and the correction accuracy will be good.

Next, the defective anode AN which has been subjected to the straightening force 1 and determined to be defective in the single weight measurement step S4 and the thickness measurement step S5 is rejected in the defective anode discharge step S6 in the putunya P2 and returned to the smelting factory. On the other hand, the above step S4. The non-defective anodes AG determined to be non-defective in S5 are divided into two systems and each undergoes an edge processing step S7. In Sy, the lower part of the ears E and E are shaped and assembled, and after the shaping is finished, they are discharged from the anode discharge step S8, and the horizontally supported anodes are branched into two or more systems and arranged in each. By performing the straightening process using the bent straightening device 3, the efficiency of the straightening process can be improved, and the production capacity of the entire shaping system can be increased.

The housing and anode transfer device are walking conveyor WC
Needless to say, the material is not limited to , and various other materials can be used.

As explained above, according to the anode bending straightening method and device of the present invention, both ears of the anode are held while the anode is held in a horizontally supported state between the receiving process and the anode discharging process after the completion of shaping. Since straightening is applied to multiple points on the anode, straightening can be stably performed on the anodes that are sequentially transported without paying attention to maintaining the balance of the anode, and the accuracy of the anode straightening process is This also has the effect of increasing processing capacity and efficiently producing a large amount of anodes with a correct shape.
