Reflux defoaming device for electroplating process tank

Abstract

The embodiment of the present invention is applicable to the technical field of electroplating and coating, and provides a reflux defoaming device for an electroplating process tank, including an electrophoresis tank, a first defoaming box, and a second defoaming box. The upper part of the electrophoresis tank has an overflow port, so The electrophoresis tank is connected to the first defoaming tank through an overflow port; the lower inner cavity of the first defoaming tank is separated by an annular partition to form an outer ring cavity and an inner circular cavity, and the inner cavity of the first defoaming tank A first defoaming assembly is also provided; the inner cavity of the second defoaming box is separated by a partition to form two chambers, the first chamber and the second chamber, and the bottom of the second chamber is higher than the first chamber. A bottom of the chamber; and the second chamber communicates with the first chamber through a connecting channel opened on the partition; a second defoaming assembly is arranged on the upper part of the second chamber. The embodiments of the present invention can solve the problem that the defoaming effect of the existing electrophoresis tank is not good and cannot meet the current processing requirements for defoaming.

Description

technical field [0001] The embodiment of the invention belongs to the technical field of electroplating and coating, and in particular relates to a reflow defoaming device for an electroplating process tank. Background technique [0002] Electroplating coating is a commonly used technical method for the post-processing of parts such as automobiles, aviation, and ships. Electrophoretic coating is a special coating film forming method. It is the most practical construction process for water-based coatings. It has the characteristics of water solubility, non-toxicity and easy automatic control. It is rapidly used in industries such as ships, automobiles, building materials, hardware and home appliances. be widely used. [0003] In the electrophoretic coating of ship parts, because the UF liquid in the UF tank for cleaning ship parts contains low-molecular resin, the air in the UF liquid will easily cause a lot of foam in the UF liquid during the cleaning process. In severe cas...
