The invention belongs to the field of electrophoresis equipment, and particularly relates to an efficient electrophoretic paint pretreatment device. The efficient electrophoretic paint pretreatment device comprises a hollow barrel, multiple feed devices, multiple discharge devices and filter devices, wherein the feed devices and the discharge devices are alternately arranged in the hollow barrel, and the filter devices are arranged between the adjacent feed devices and the discharge devices. Each feed device comprises a vertical feed pipe and an overflow stopping cover for preventing filter liquor from overflowing upwards, wherein the overflow stopping cover and the vertical feed pipe are communicated to form a filter liquor feed channel, and the edge of the overflow stopping cover is connected with the inner wall of the hollow barrel in a sealed mode; each discharge device comprises a funnel-shaped discharge hopper body, wherein the bottom of the discharge hopper body is connected with the top of the vertical feed pipe of the next feed device; each filter device comprises a conical filter plate and a filter residue collecting plate, wherein the conical filter plate is located below the corresponding overflow stopping cover and arranged coaxial with the corresponding vertical feed pipe, and the filter residue collecting plate is arranged on the bottom edge of the conical filter plate in an enclosing mode. A heating device is arranged at the bottom of the hollow barrel. The electrophoretic paint pretreatment device has the advantages of being good in filtering effect and capable of carrying out heating, and filter residues are easy to clear.
