Problems solved by technology

The traditional galvanizing production process generally uses the zinc plate as the anode for rack plating or barrel plating. Due to the limitations of the process and equipment itself, there are the following problems: the dissolution of the zinc plate in the plating tank brings impurities into the bath, When the quality of the zinc plate is not good, it will seriously affect the quality of the galvanized layer; when the zinc ion content of the galvanizing bath decreases, sodium hydroxide is needed to dissolve the zinc oxide to increase the zinc ion content, so that not only the impurities in the zinc plate It still exists in the plating tank, and it is difficult to monitor and the deployment cycle is long, which affects the quality of the coating and the consistency of the product
Due to the difficult control of the electroplating solution and the poor quality of the product, it is difficult to meet the mass production

Abstract

The invention discloses an electroplating device for galvanization of alkaline solution. The device comprises an electroplating tank (1), a filtering machine (3) and a dissolving tank (5), wherein the electroplating tank (1) is communicated with the filtering machine (3) by virtue of a pipeline A (2); the filtering machine (3) is communicated with the dissolving tank (5) by virtue of a pipeline B (4); the electroplating tank (1) comprises an electroplating tank body (9) and an anode (10); a filter plate (8) is arranged inside the filtering machine (3). The device is characterized in that a joint of the pipeline A (2) is positioned above the filter plate (8); a joint of the pipeline B (4) is positioned below the filter plate (8); the dissolving tank (5) consists of a dissolving tank body (7) and a frame body (6); the frame body (6) is arranged inside the dissolving tank body (7); an electronic monitoring system is connected with the electroplating tank (1), the filtering machine (3) and the dissolving tank (5). The device has a simple structure, and is stable in performance, and efficient and practical; the raw materials are reduced.

Description

technical field [0001] The invention belongs to the technical field of chemical electroplating, and in particular relates to an electroplating device for galvanizing with an alkaline solution. Background technique [0002] Common galvanizing production is divided into acid galvanizing and alkaline galvanizing according to different bath solutions, among which the effect of alkaline galvanizing is the best. The traditional galvanizing production process generally uses the zinc plate as the anode for rack plating or barrel plating. Due to the limitations of the process and equipment itself, there are the following problems: the dissolution of the zinc plate in the plating tank brings impurities into the bath, When the quality of the zinc plate is not good, it will seriously affect the quality of the galvanized layer; when the zinc ion content of the galvanizing bath decreases, sodium hydroxide is needed to dissolve the zinc oxide to increase the zinc ion content, so that not o...
