Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus used for electrolytically refining metals by inserting or suspending electrode plates into an electrolytic tank and moving the electrode plates. The present invention relates to a device that can change the distance.

For example, in the electrolytic refining of copper, the cathode is usually electrodeposited twice for one life of the anode.
The distance between the electrodes is set so that the initial distance between the cathode and the anode is the minimum in order to maximize productivity within the same electrolytic cell space and to prevent short circuits. Therefore, when a new cathode is electrodeposited for the second time in the second half of the anode's life, the anode has been eluted and the thickness has become thinner.
If electrolysis is continued without changing the distance between the electrodes as in the past, the distance between the anode and the cathode increases, resulting in an increase in electrical resistance during electrolysis, resulting in an increase in power loss. The above problem can be solved by reducing the distance between the electrodes by the amount of the reduction in the thickness of the anode during the second electrodeposition collection of the cathode.
It is impossible to move a large number of heavy electrodes by hand, and moving them one by one using a crane is laborious and time consuming, which is impractical.
In addition, if you try to change the electrode spacing for one tank outside the electrolytic cell, it will require a large amount of equipment cost and a large space.
Problems arise, such as the need for two methods, one with reduced spacing and the other with reduced spacing.

The present invention aims to eliminate the above-mentioned drawbacks, and in order to achieve this purpose, a plurality of electrodes can be suspended by configuring this electrode plate hanging device as described in the claims. To provide a device that can change the distance between poles while suspended by a tool.

An embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a plan view of the device of the present invention, FIG.
The drawings are a side view of FIG. 1, FIG. 3 is a partial sectional view of the front of FIG. 1, and FIG. 4 is a perspective view of the support.

As shown in FIG. 4, the hook 1 for suspending the electrode plate is held at the center of the support 2 so that it can rotate about the center line but cannot move in the axial direction, and the hook 1 is held in the center of the support 2 so that the center line coincides with the top. It can be rotated by a fixed gear 3. The thickness b of the support 2 in the electrode plate arrangement direction is equal to the distance between the anodes or cathodes when the second cathode is placed relative to the anode. Two rollers 4 are disposed at the lower portions of both sides of the support 2, and the support 2 has two frames 5 having a U-shaped cross section with their inner sides facing each other, and a hook 1 protrudes from between the frames 5. A large number of rollers 4 are housed in a line, and the rollers 4 move on guide rails 6 disposed within the frame 5 and along the frame 5. Further, two pins 7 protrude from the head and both sides of the support 2, and the opposing pins 7 of two adjacent supports 2 are loosely connected by a ring-shaped connector 8. Connector 8 connects adjacent support 2
When the protruding pins 7 come to both ends of the connector 8, the sum of the distance s between both supports and the thickness b of the support 2 is the same polarity when the cathode is first placed relative to the anode. The distance between the poles is now the same.

A desired number of supports 2 having such a structure are stored, and two sets of frames 5 having a length that can be set to the distance between the anodes or cathodes when the first cathode is placed relative to the anode are placed parallel to each other. and the both ends thereof are connected to frames 13 and 13a.
The two rows of hooks are fixed in a rectangular frame shape so that the distance between them matches the hanging position of the electrode plate.

A common shaft 10 is arranged along the side surface of the gear 3 fixed to the top of each hook 1.
Both ends are supported by bearings 17 and 17a provided on frames 13 and 13a. Each gear 3 has
A rotation gear 9 is engaged at right angles to this. The rotation gear 9 has a key 11 fixed to it and protrudes inward.
It is held by the common shaft 10 and the support 2 so that it can move along the common shaft 10 in the axial direction while meshing with the gear 3 along with the support 2 by means of a keyway 12 provided in the common shaft 10. As shown in FIGS. 1 and 2, each common shaft 10 projects outward from the frame 13a, and a handle 19 serving as a device for rotating the common shaft 10 is fixed to each of the projecting parts. Install the motor,
The two rotating shafts 10 may be rotated simultaneously by a motor so that the hook of the hook 1 is oriented parallel to the frame 5 or rotated by 90 degrees.

The frame 13 has a small U-shaped frame 1 extending outward.
A threaded rod 15 is fixed at right angles to a rectangular frame-like frame surface and has both ends pivotally supported by a frame 13 and a small frame 16. A handle 18 is fixed to the projecting end. A threaded cylinder 21 is fitted into the threaded rod 15, and a member 14 extending to the frames 5 on both sides is integrally provided to the threaded cylinder 21.Both ends of the member 14 are connecting rods 14a and 14b, as shown in FIGS. It is connected to the support 2 at the right end in the figure. In this embodiment, the left end support 2 is fixed to the frame 13a, and by rotating the handle 18, the chain of supports 2 can be stretched or compressed. Figures 1 and 2 show a state in which the distance between the supports 2 is increased and the distance between the hooks 1 is increased to match the distance between the anodes or cathodes when the cathode is first placed relative to the anode. ing. When the handle 18 is turned and the supports 2 are brought into contact with each other, the distance between the hooks 1 is made equal to the distance between the anodes or cathodes when placing the cathode against the anode for the second time. .

The thickness b of the support 2 in the continuous direction is made smaller than the distance between the anodes or cathodes when the second cathode is placed with respect to the anode, and the contact distance between adjacent supports 2 is reduced using the connector. It may be regulated. Further, the device for approaching or separating the mutual spacing between the supports consisting of the handle 18, threaded rod 15, threaded cylinder 21, etc. may be composed of a motor, a transmission shaft, a cap gear, etc., and only from one end of the support device row. Alternatively, the support row may be extended or compressed from both ends. In the figure, reference numeral 20 denotes a hanger for hanging this device from a crane for moving electrodes installed in the building.

The device of the present invention is hung from a crane for moving electrodes using a hanger 20, and the handle 18 is turned to extend the row of supports 2 as shown in the figure, and the distance between the hooks 1 is adjusted so that the initial cathode is positioned relative to the anode. The distance between the cathodes when

Next, turn the handle 19 so that the hook of the hook 1 is parallel to the electrode plate. In this state, it is moved to the top of the electrolytic bath where the first electrodeposition has been completed. Then, the device is lowered, and the hook of each hook is inserted between the anode and the cathode so that it is positioned slightly below the handle of each cathode, and the device is temporarily stopped there. Then, turn the handle 19 so that the hook of the hook 1 is placed under the cathode handle so that it is perpendicular to the cathode handle. Then, raise the device, suspend multiple cathodes at the same time, transport it to another location, lower it, hang both ends of the cathode hanger on the support device, and rotate the hook of hook 1 parallel to the cathode hanger. , raise the device. Return the device to the same electrolytic cell again, and this time lift up the anode in the same way, turn the handle 18 while it is lifted, and adjust the distance b of the hook 1 so that it is the same as the pole between the anodes when placing the cathode against the anode for the second time. The apparatus is lowered and returned to the electrolytic cell, and the hook 1 is set parallel to the anode and removed from the anode. Next, move hook 1 to the cathode storage area without changing the spacing between hooks 1 and 1.
The cathodes arranged at intervals of 2 are lifted up and transferred to the same electrolytic cell, inserted so that the cathode is located between each anode, the hooks are removed from the cathodes, and the device is raised.

In addition, if a device similar to this device is installed inside the device so that the anode and cathode can be lifted at the same time, the number of crane movements can be reduced, making it possible to shorten the distance between poles even more quickly. .

It goes without saying that the device of the present invention can be applied not only to electrodes for electrolysis but also to other fields where it is necessary to change the pitch of suspended objects.
