The present invention is to improve the corrosion resistance of the steel sheet or to clean the electrolyte by filtering various impurities such as sludge generated in the electrolyte stored in the plating cell during the electroplating of the steel sheet to plate the cold rolled steel sheet with a specific component according to the demand of the consumer The present invention relates to an electrolytic cleaning apparatus in a plating cell. More specifically, it is possible to improve the plating quality of a steel sheet by cleaning impurities by effectively removing impurities contained in the electrolyte in the plating cell without manual labor. Electrolytic solution cleaning device in a steel plate plating cell.

In general, when manufacturing a cold rolled steel sheet in a steel mill, plating is performed on the surface of the steel sheet. The plating operation of the steel sheet is performed by passing the steel sheet through a plating bath in which molten metal is stored, or performing surface plating of the steel sheet, or electrolytic solution in the plating cell. There is an electroplating method to perform the surface plating of the steel sheet while advancing the steel sheet by passing through the conductor roll with the + component anodes and-electrode bands to be filled and plated. In addition to improving the corrosion resistance of the steel sheet and plating the components desired by the consumer in accordance with the use environment of the steel sheet, the electroplating operation of such a steel sheet is shown in FIG.

That is, as shown in FIG. 1, the anodes 120 are installed through the bridge 122 in the plating cell 110 filled with the electrolyte solution 100 through the electrolyte supply pipe 112 and the anode 120. The conductor roll 130 is provided with a band 132 of the electrode to which the steel sheet S is wound and transported at a predetermined interval.

Accordingly, the steel sheet S, which is in close contact with the electrode band 132 of the conductor roll 130, has a negative electrode, and the positive ion of the anode 120, for example, zinc ions is an electrolyte solution 100. The plated work of the steel sheet is performed while moving through and attached to the surface of the steel sheet (S).

However, during the electroplating of such a general steel sheet, when using with various sludges 140 generated in the bridge 122 and the anode 120 of the metal component from the outside when the anode 120 is reduced in volume Impurities, such as foreign matter, are easily contained in the electrolyte 100, which impairs the plating of the steel sheet and, in particular, causes defects on the surface of the steel sheet in a later step.

In addition, the impurity 140 contained in the electrolyte 100 causes the current to be uneven, resulting in poor plating of the electroplated steel sheet, and eventually plating quality of the steel sheet due to poor plating along with surface defects of the steel sheet S. This lowers the product reliability of the demand.

However, in the related art, in order to remove the impurities 140 included in the electrolyte solution 100 in the plating cell 110, the operator may stop the operation of the plating line manually by using a separate jig. Although the impurities 140 have been removed, this is not only difficult to work, but there is a high possibility that a safety accident of an operator occurs, and in particular, because the work is delayed, there are problems that the steel plate plating operator is delayed.
