The liquid separator is evenly provided with discharge holes, and a feed extraction port is provided at the bottom of the side of the body. The feed extraction port is connected to the circulating slurry outside the body through a conduit, and the circulating slurry is connected to the feed port 1 through the conduit. By setting up this kind of electrophoretic paint mixer, the electrophoretic paint enters the body through the discharge holes on the liquid separator, and then is broken up by the stirring rod, so that the electrophoretic paint can be stirred more evenly inside the body 1. Through the circulating stirring device on the body, the electrophoretic paint above and below the body forms a strong convection, and the electrophoretic paint is circulated and stirred, which improves the stirring effect.
