Zinc or zinc-nickel electroplating production line zinc dissolution device

Abstract

The invention belongs to the technical zinc dissolution and discloses a zinc or zinc-nickel electroplating production line zinc dissolution device which comprises a plating tank, a zinc dissolution tank and a regulation tank; an overflow groove is welded to the top end of the right side wall of the plating tank and is connected with a pipeline of the zinc dissolution tank through a first valve anda pipeline of the regulation tank through a three valve; the zinc dissolution tank is internally provided with a plurality of zinc dissolution frame baskets and communicates with the regulation tankthrough an overflow pipe which is welded with the upper end of the right side wall of the zinc dissolution tank and a pipeline which is provided with a second valve; the lower left side of the regulation tank is connected with a pipeline of a circulation pump through a fourth valve; and a filter is connected to an outlet pipeline of the circulation pump, passes through a fifth valve and communicates with the zinc plating tank through a pipeline. For the zinc electroplating or zinc-nickel production line zinc dissolution device provided by the invention, switching among the valves or starting or stopping of a circulation filter pump is needed only, the content of zinc in an zinc or zinc-nickel electroplating solution can be conveniently regulated, and safe perfect combination with trouble conservation.

Description

technical field [0001] The invention belongs to the technical field of zinc dissolving, and in particular relates to a zinc dissolving device for an electrogalvanizing or zinc-nickel production line. Background technique [0002] At present, the zinc dissolving device of the alkaline galvanizing or zinc-nickel electroplating production line is basically composed of a plating tank, a zinc dissolving tank, an iron anode blue with zinc ingots, an electric hoist, a circulating filter and its pipeline. During work, the plating tank solution flows into the zinc dissolving tank through the overflow bucket, and finally pumped into each main plating tank by the filter circulating pump to complete the closed cycle. If the zinc content is higher or lower than the process range, there is a risk of poor electroplating. During normal production, it is required to accurately control the zinc content in the solution within the process range. When the production is stopped in one shift or tw...
