Description

TECHNICAL FIELD The present invention relates to an electrolytic plating device, and more particularly to an anode exchange device for a continuous electrolytic plating device for steel strip.

[Conventional technology]

FIGS. 7, 8 and 9 show an example of a conventional apparatus for continuously plating a steel strip using a soluble anode. The soluble anode refers to one in which the anode is electrolyzed and dissolved in the plating bath solution by energizing an electric circuit for plating.

In FIG. 7, while the steel strip 1 is guided by the conductor rolls 4a, 4b and the deflector roll 5 and passes through the plating bath liquid 3 in the plating bath 2, the opposite soluble anodes 6a, 6b, 6c, 6
The metal melted in the plating bath solution 3 from d causes the plating to occur. Therefore, the soluble anodes 6a to 6d are consumed according to the amount of electricity that has been energized due to the plating, so when the consumption becomes remarkable, they are replaced with new ones.

FIG. 8 is an enlarged view of the soluble anode portion shown in FIG.
FIG. 9 is a view showing the arrow A, in which the soluble anode 6a is a metal plate having a certain height and arranged to have a width substantially the same as the width of the steel strip 1. upper end has a鉤様and lower ends Furatsuka not as anode guide 9a, and thin summer as clamping customers to 9a ₁ to be by connexion suspended the bar 7.

Further, the soluble electrode 6a --- may be divided into a plurality of strip-shaped blocks (not shown) instead of a single plate as shown in FIG.

[Problems to be solved by the invention]

Soluble anode 6a ----- is large and small, but generally 10 kg
It has a weight of (strip) to several hundred kg (single plate). In order to replace such a soluble anode, it is common to manually pull it down, suspend it with a chain block or a crane, and remove the metal tank cover which is an obstacle at that time prior to replacement, or The cover has an opening.

In particular, in the case of a plating device that is operated poorly under special plating conditions such as continuous electrolytic plating device that uses molten salt (high temperature, generation of harmful gas, shutoff from the atmosphere, etc.), the soluble anode is replaced by the above means. However, there were problems in terms of workability, safety, influence on the plating treatment conditions, and the like.

Further, there has been a demand for reduction of replacement work time and improvement of productivity.

The present invention proposes an anode exchange device for a continuous electrolytic plating device which solves the above problems.

[Means for solving problems]

The present invention solves the above-mentioned problems by providing a soluble anode exchanging carriage that is hermetically connected to an opening having an openable gate provided on the side wall of a plating tank of an electrolytic plating apparatus that uses a soluble anode and that can be cut off. , Is something to solve.

That is, the present invention relates to an exchange cart connected to an opening / closing gate section provided on a side wall of a plating tank of an electrolytic plating apparatus using a soluble anode, and the anode in the cart in a state where the cart is connected to the gate section. An anode of an electrolytic plating apparatus provided with an exchange box movable in a direction orthogonal to the rail, a rail provided on the top of the exchange box for suspending and moving the anode, and means for horizontally moving the anode. Regarding switching equipment.

[Action]

In the present invention, a soluble anode exchange carriage having a new anode mounted in advance and an empty exchange box is connected to an opening provided in the side wall of the metal plating tank, and a gate provided in this opening is opened from the outside. From here, first, the consumable anode in the plating tank is moved to an empty exchange box of the exchange cart, then the new anode in the exchange box is moved to the plating tank, and this new anode is suspended by the current-carrying bar. After that, close the gate again, disconnect the anode exchange cart,
Restart the operation.
