Description

[Detailed description of the invention] The present invention simplifies charging into the electrolytic cell by arranging a plurality of anode plates and cathode plates alternately in advance in the electrode plate arrangement state in the electrolytic cell. The present invention relates to a device for automatically and alternately combining anode plates and cathode plates, which simplifies and eliminates electrode correction work such as position correction after loading.

Generally, in electrolytic refining of non-ferrous metals such as copper and lead, blister copper or crude lead obtained by dry method or other methods is used as the anode plate, and a sheet of pure copper or pure lead obtained by electrolysis method is used as the cathode. It is used as a board.

These anode plates and cathode plates are alternately combined and charged and arranged in an electrolytic cell, but conventionally, the anode plate and the cathode plate were separately charged and arranged.

If the arrangement or combination of electrode plates is carried out using one transport means, it takes time to load the electrode plates, which reduces the operating time of the electrolytic cell.

Therefore, attempts were made to improve efficiency by transporting the anode plate and cathode plate using separate transport means, but having separate transport equipment also led to a decrease in the operating efficiency of transport equipment such as overhead lanes, resulting in a reduction in transport efficiency. Furthermore, in an electrolytic factory having a large number of electrolytic cells, interference between cranes may occur, which ultimately reduces the operating rate of the electrolytic cells.

In order to perform electrolytic refining, it is necessary to adjust the position of the anode plate and cathode plate in the width direction in the electrolytic cell, but when the electrode plates are charged separately as in the past, the position of the electrode plate is Corrections had to be made on the electrolytic cell, which required a great deal of effort and time.

In order to solve the above-mentioned drawbacks in charging and arranging anode plates and cathode plates into an electrolytic cell in electrolytic refining, the present invention combines an anode plate and a cathode plate before charging into an electrolytic cell. It is an object of the present invention to provide a device for performing these position adjustments, and the structure of the present invention for achieving this purpose is to use a combination array conveyor that carries anode plates arranged at a constant pitch. An installation position is determined midway, and when a predetermined number of anode plates arrive at the installation position, the combination array conveyor is stopped, and the anodes are moved in a direction perpendicular to the direction of movement of the combination array conveyor to remove the stopped anodes. A guide member for guiding the cathode plates inserted between the plates is provided at the assembly position, and a cathode plate arrangement conveyor is provided at the assembly position for arranging a predetermined number of cathode plates suspended from a crossbar at the same pitch as the anode plates. The cathode plate is installed parallel to the conveyor, one of the cathode plate and the crossbar is regulated by a positioning member, and the other is pushed by an extrusion member, so that the position of the cathode plate in the width direction relative to the longitudinal direction of the crossbar is adjusted to match the shape of the anode plate. The cathode plate array conveyor is equipped with a transfer device for changing the position of the cathode plate array conveyor, and a transfer assembly device equipped with a lifting device that can lift and lower the cathode plates by holding a crossbar is installed on the cathode plate array conveyor from above the cathode plate array conveyor. After changing the position of the cathode plates arranged on the cathode plate arrangement conveyor and the crossbar, the crossbar is held by the hanging device of the transfer and installation device. The cathode plates are hung and transferred to the assembly position, and inserted between the anode plates supported by the combination array conveyor via the guide member, so that the anode plates and the cathode plates are combined. It is characterized by

In the electrolytic cell, the anode plates and the cathode plates are arranged alternately in a predetermined number at regular intervals with their faces facing each other, and the cathode plates are assembled so as to be slightly shifted toward the current introduction side with respect to the anode plate.

By shifting the cathode plate toward the current introduction side, the current distribution within the electrolytic cell becomes uniform, and the thickness of the product cathode (electrodeposited metal plate) can be made uniform regardless of whether it is on the current introduction side or the outflow side.

In the present invention, the arrangement and combination of anode plates and cathode plates is carried out by stopping the combination arrangement conveyor when a predetermined number of anode plates arranged at a constant pitch and carried by the combination arrangement conveyor reach a predetermined position (installation position). The cathode plates, which are arranged at the same pitch as the anode plates and supported by the cathode plate arrangement conveyor, are carried by a transfer and installation device, and are inserted between the anode plates stopped at the installation position, and the cathode plates are also combined and arranged. This is done by supporting it on a conveyor.

In addition, before the cathode plates are inserted between the anode plates, the positions of the cathode plates are adjusted (repositioned) on the cathode plate array conveyor according to the shape of the anode plates supported on the combination array conveyor. .

The hook 42 rotates due to the link movement caused by the cylinder.

The links are combined so that this rotation angle is approximately 90 degrees, and by rotating 90 degrees, the hooks 43 of the hooks 42 are in a state facing each other, that is, the cathodes supported on the cathode plate arrangement conveyor 4. The state changes from being parallel to the plate 3 to being parallel to the traveling direction of the conveyor 4.

The transfer/installation device 26 for lifting and carrying the cathode plates 3 and loading them between the anode plates 1 must be stopped at a predetermined position above the installation position of the cathode plate arrangement conveyor 4 and combination arrangement conveyor 2.
