Electrophoretic paint recovering and spray water washing system

Abstract

The invention provides an electrophoretic paint recovering and spray water washing system. The system comprises an electrophoretic paint tank (1), ultrafiltration tanks (2), pure water washing tanks (3), ultrafiltration liquid supply pumps (4), first filters (5), ultrafiltration modules (6), tank liquid discharge pipes (7), tank liquid discharge valves (8) and tank body communicating pipes (9). The tops of the ultrafiltration tanks (2) communicate with the tops of the pure water washing tanks (3) through the tank body communicating pipes (9), and the ultrafiltration tanks (2) and the pure water washing tanks (3) have liquid level differences from low to high, so that the electrophoretic paint recovering and spray water washing system can effectively recover electrophoretic paint in the pure water washing tanks, and the loss of partial electrophoretic paint and the pollution caused to the environment in the process that sewage treatment is performed on the electrophoretic paint can be avoided.

Description

technical field [0001] The invention relates to the technical field of tooling for vehicles, in particular to an electrophoretic paint recovery and spray water washing system. Background technique [0002] In the electrophoresis process of automobile body painting, the electrophoresis body needs to be cleaned by ultrafiltration and pure water washing process. On the one hand, it is to ensure the quality of the electrophoretic paint film on the body, such as eliminating the electrophoretic paint flow marks on the body and improving the gloss of the body. etc. On the other hand, because the body surface after electrophoresis has a large amount of electrophoretic paint, it is necessary to recycle these redundant electrophoretic paints, thereby saving production costs. [0003] At present, the ultrafiltration system device is generally used to recover the electrophoretic paint in the ultrafiltration (Ultra-filtration, UF) bath after the body electrophoresis cleaning, such as fi...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide an electrophoretic paint recovery and spray washing system to solve the problem that the prior art cannot recover the electrophoretic paint in the pure water washing tank, resulting in the loss of part of the electrophoretic paint liquid and polluting the environment
