Automatic on-line analysis electrophoresis tank

Abstract

The invention relates to an electrophoretic coating device, in particular to an automatic on-line analysis electrophoresis tank. The automatic on-line analysis electrophoresis tank comprises a main tank, wherein a liquid outlet and a liquid return port are formed in the main tank, a circulating pipeline connected to the liquid outlet and the liquid return port is arranged outside the main tank, and a circulating stirring pump is arranged on the circulating pipeline; the automatic on-line analysis electrophoresis tank is characterized by further comprising an assay analysis tank, wherein a liquid outlet pipeline is connected between the assay analysis tank and the main tank, and an electromagnetic valve is arranged on the liquid outlet pipeline; a concentration sensor is arranged in the assay analysis tank, and the concentration sensor is connected to an electric controller through a wire; and the electromagnetic valve is connected to the electric controller through the wire. Accordingto the automatic on-line analysis electrophoresis tank, the components of the electrophoretic paint in the main tank can be automatically analyzed, manual sampling is not needed, the production line is not need to stop, the production efficiency can be improved, and the labor cost can be reduced.

Description

technical field [0001] The invention relates to an electrophoresis coating device, in particular to an automatic on-line analysis electrophoresis tank. Background technique [0002] As we all know, electrophoretic coating is one of the most effective methods for coating metal workpieces. The principle is to immerse the conductive coated object (metal workpiece) in the main tank filled with electrophoretic paint with a relatively low concentration diluted with water as the anode (or cathode), and set a corresponding cathode in the main tank ( or anode), after a period of direct current between the two poles, a uniform, fine, water-insoluble coating film is finally deposited on the surface of the object to be coated. [0003] When the electrophoretic production line is in operation, the electrophoretic paint will have normal loss, and it is necessary to continuously add the electrophoretic paint base liquid to ensure the stability of the electrophoretic paint composition and ...

AI Technical Summary

Problems solved by technology

In order not to affect the normal operation of the production line as much as possible, manual sampling often needs to wait until after get off work (the production line stops running), so that the sampling and testing personnel must work overtime to complete the sampling and analysis work

It can be seen that such manual sampling and analysis operations make the electrophoresis production line unable to run continuously for a long time, which not only affects production efficiency, but also consumes a lot of labor costs
