Problems solved by technology

[0005] (1). When the anode tube module is damaged and other liquids such as electrophoretic fluid seep into the pure anolyte, the anode system cannot give an alarm in time;
[0006] (2). When the anode tube module is damaged and other liquids such as electrophoretic fluid infiltrate into the pure anolyte, the anolyte of the entire anode system needs to be completely replaced, which wastes production costs;
[0007] (3). When the current parameters of some anode tubes in the electrophoresis anode system are abnormal, the anolyte circulation pump system needs to be manually shut down, which cannot guarantee the normal production;

Abstract

The invention discloses an automobile coating anolyte circulation protection system comprising an anolyte storage tank, a circulating pump, an anode tube, an anolyte surge tank, a first shunt three-way valve, a turbidimeter and a waste liquid tank; the anolyte storage tank, the circulating pump, the anode tube, the anolyte surge tank and the first shunt three-way valve communicate in order, and a first outlet of the first shunt three-way valve communicates with the anolyte storage tank. A second outlet of the first shunt three-way valve communicates with the waste liquid tank; the first shunt three-way valve has at least two working states: in the first working state, the first outlet is opened, and the second outlet is closed; in the second working state, the first outlet is closed, and the second outlet is opened; the turbidimeter is installed on a pipeline for communicating with the anode tube and the anolyte surge tank, and connected to the first shunt three-way valve; and the turbidimeter is used for detecting the purity of anolyte flowing out of the anode tube, and controlling the working state of the first shunt three-way valve according to the detection result. In the automobile coating anolyte circulation protection system, waste of the anolyte can be reduced.

Description

technical field [0001] The invention relates to the technical field of automobile painting, in particular to an anolyte circulation protection system for automobile painting. Background technique [0002] During the electrophoresis process of automobile body painting, in order to achieve timely electroplating of electrophoretic paint on the body-in-white, an anode system needs to be designed in the electrophoresis tank to provide an electric field for the electrophoresis of the body. However, once the anode module is damaged or some anode tubes have abnormal current failure, the It will pollute the pure anolyte or affect the normal production. In serious cases, it will cause the production line to stop production or even the quality of the car body to fail to meet the standard. [0003] At present, the electrophoresis anode system generally uses two anolyte circulation pumps, please refer to figure 1 , figure 1 It is a schematic structural diagram of an electrophoresis ano...
