Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an electrolytic plating apparatus, particularly to an anode exchange apparatus for a continuous electrolytic plating apparatus for steel strip.

[Conventional technology]

Figures 7.8 and 9 show an example of a conventional continuous plating device for copper strips using a soluble anode. A substance that is released into the plating bath solution.

In Fig. 7, the steel strip 1 is connected to conductor rows 4a, 4b.
, while being guided by the deflector row A15 and passing through the plating bath solution 3 in the plating tank 2, the opposing soluble anode 6
A, 6b, 6c, and 6d are plated with the metal dissolved in the smearing bath solution 3. Therefore, the soluble anode 6a~
The 6d is consumed depending on the amount of electricity applied for plating, so when it becomes significantly worn, it is replaced with a new one.

Figure 8 is an enlarged view of the soluble anode portion shown in Figure 7;
FIG. 9 is a view showing the arrow A, and the soluble anode 6a
is a metal plate arranged with approximately the same width as the width of the copper strip 10 and has a certain height, and is fixed to the anode bridge 8.

Further, the soluble electrodes 6a-m- may be formed into a single plate as shown in FIG. 9, or may be divided into a plurality of strip-shaped blocks (not shown).

[Problem that the invention seeks to solve]

The soluble anode 6a is available in various sizes, large and small, but generally weighs from several 10 kg (strip shape) to several 100 kg (single plate). To replace such a soluble anode, it is common to lift it manually or suspend it using a chain block or crane.In this case, the plating tank cover that becomes an obstacle must be removed before replacement, or the An opening is provided in the cover.

In particular, in the case of plating equipment that is operated under special plating conditions (high temperature, generation of harmful gas, need to shut off atmospheric pressure, etc.) such as continuous electrolytic plating equipment that uses molten salt, the soluble anode should be replaced using the above method. This has caused problems in terms of workability, safety, influence on plating processing conditions, etc.

Additionally, there was a need to shorten replacement work time and improve productivity.

The present invention proposes an anode exchange device for a continuous electrolytic plating apparatus that solves these problems.

[Means for solving problems]

The present invention solves the above problem by providing a soluble anode exchange cart that can be connected and disconnected in a sealed manner to an opening having a gate that can be opened and closed provided on the side wall of a plating tank of an electrolytic plating apparatus using a soluble anode. Yes, it will be resolved.

That is, the present invention provides 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 an exchange truck connected to the gate section in the exchange truck, and an exchange truck connected to the gate section in an electrolytic plating apparatus using a soluble anode.

Relating to a switching device.

[Effect]

In the present invention, a soluble anode exchange cart on which a new anode has been previously installed and an empty exchange box is connected to an opening provided in the side wall of the plating tank, and a gate provided in this opening is opened from the outside. Open the plating tank, and from here first transfer the consumable anode in the plating tank to the empty replacement box of the replacement cart, then transfer the new anode in the replacement surface to the plating tank, and suspend this new anode on the energizing bar. After that, the gate is closed again, the anode exchange cart is disconnected, and operation is resumed.
