Cleaning device for plating bath

PURPOSE: To enable the production of an excellent plated product by efficiently removing the dross in a plating bath and cleaning the plating bath without interrupting a continuous plating operation. CONSTITUTION: The dross 21 which is lifted together with a plating liquid by a gas lift pump into a gas-liquid separator 4 and floats near a liquid surface 20 in the separator 4 is discharged together with the plating liquid to the outside from a discharge port 5 which is a dross separating discharge system. The dross tending to fall in the separator 4 is spouted from a piping 7 and is adsorbed by the gaseous bubbles 32 fined by a filter 6, by which the dross is floated. This dross is again discharged from the discharge port 5. The dross remaining still is captured by the filter 6. The remaining plating liquid is returned into the plating bath from the return pipe 41 of the separator 4. COPYRIGHT: (C)1993,JPO&Japio
