Waste gas collecting device for rack plating tank

Technical Field

The application relates to the technical field of electroplating processing, in particular to a waste gas collecting device for a rack plating tank.

Background

The rack plating is also called 'hanging plating', and is a mode of electroplating processing, namely, a rack is adopted to hang a workpiece and electroplating is carried out. The method is suitable for large parts, and the process has the advantages that the number of products capable of being plated in each batch is small, and the plating thickness is more than 10 mu m, such as bumpers of automobiles, handlebars of bicycles and the like. Common plating layers such as chromium plating do not act in most organic acids such as alkali, sulfide, nitric acid and the like due to good chemical stability, and are widely applied to the production of various parts.

In the traditional chromium plating process, an operator needs to perform pretreatment, such as acid washing, alkali washing and water washing, on a plated object, then the plated object is placed in a rack plating tank carrying corresponding chemical electrolyte, and an electroplated layer is formed on the surface of the plated object through electrification, wherein the chemical electrolyte is usually a metal solution such as chromium chloride.
