Efficient electrophoretic paint filtering device

Abstract

The invention belongs to the field of electrophoresis equipment and particularly relates to an efficient electrophoretic paint filtering device. The efficient electrophoretic paint filtering device comprises a hollow barrel, a plurality of feeding devices and discharging devices and filter devices, the feeding devices and the discharging devices are alternately arranged in the hollow barrel, and each filter device is arranged between every two adjacent feeding device and discharging device. Each feeding device comprises a vertical feeding pipe and a conical anti-overflow cover for preventing filtrate from overflowing upwards, wherein the conical anti-overflow cover is communicated with the vertical feeding pipe to form a filtrate inlet passage, and the edge of the conical anti-overflow cover is hermetically connected with the inner wall of the hollow barrel. Each discharging device comprises a funnel-shaped discharging hopper, wherein the bottom of the discharging hopper is connected with the top of the vertical feeding pipe of the next feeding device. Each filter device comprises a conical filter plate and a filter residue collection plate, wherein the conical filter plate is positioned below the corresponding anti-overflow cover and coaxial with the corresponding vertical feeding pipe, and the filter residue collection plate is arranged surrounding the bottom edge of the corresponding conical filter plate. A heating device is arranged at the bottom of the hollow barrel. The efficient electrophoretic paint filtering device has advantages of excellent filter effects, easiness in clearing of filter residues and availability for heating.

Description

technical field [0001] The invention belongs to the field of electrophoretic equipment, and in particular relates to a high-efficiency electrophoretic paint filter 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 of the...

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
