A high-efficiency electrophoretic paint pretreatment device

Abstract

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.

Description

technical field [0001] The invention belongs to the field of electrophoretic equipment, and in particular relates to a high-efficiency electrophoretic paint pretreatment device. Background technique [0002] Electrophoresis is a commonly used process in coating metal workpieces. Before the electrophoretic paint is put into the tank on the electrophoretic coating line, it must be pre-treated. The pre-treatment of electrophoretic paint generally includes stirring, filtering, heating and so on. The existing electrophoretic paint pretreatment process has the following disadvantages: 1. The filtering effect of the existing electrophoretic paint filter device is not ideal, and the dust particles, condensed dirt and even mechanical impurities in the electrophoretic liquid cannot be removed in time, and the gloss of the workpiece after drying cannot be guaranteed. The quality of electrophoresis is not very high, and it cannot meet the development needs of modern industry. 2. Some ...

Problems solved by technology

The existing electrophoretic paint pretreatment process has the following disadvantages: 1. The filtering effect of the existing electrophoretic paint filter device is not ideal, and the dust particles, condensed dirt and even mechanical impurities in the electrophoretic liquid cannot be removed in time, and the gloss of the workpiece after drying cannot be guaranteed. degree, paint film thickness, and the quality of electrophoresis is not very high, which cannot meet the development needs of modern industry

2. Some of the existing electrophoretic paint filter devices have only one layer of filter screen. After a long time, the filter residue will block the filter holes and affect the filtering effect. Moreover, the filter residue is not easy to clean, which will affect the subsequent filtration of the electrophoretic liquid.

3. The existing electrophoretic paint treatment process separates these processes, resulting in a large equipment footprint and low treatment efficiency
