Backflow defoaming device of electroplating process tank

Abstract

The embodiment of the invention is suitable for the technical field of electroplating coating, and provides a backflow defoaming device of an electroplating process tank. The backflow defoaming device comprises an electrophoresis tank, a first defoaming box and a second defoaming box. The electrophoresis tank is provided with an overflow opening in the upper part thereof, and the electrophoresis tank is connected with the first defoaming box through the overflow opening. An inner cavity in the lower part of the first defoaming box is divided into an outer ring cavity and an inner circular cavity through an annular partition plate, and a first defoaming assembly is further arranged in the first defoaming box. An inner cavity of the second defoaming box is divided into a first cavity and a second cavity through a partition plate, and the bottom of the second cavity is higher than the bottom of the first cavity. The second cavity is communicated with the first cavity through a connecting channel formed in the partition plate. A second defoaming assembly is arranged at the upper part in the second cavity. According to the embodiment of the invention, the problem that the defoaming effect of the existing electrophoresis tank is poor and the current defoaming treatment requirement cannot be met can be solved.

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...
