An electrophoretic paint filter device with filter residue cleaning function

Abstract

The invention belongs to the field of electrophoresis equipment and relates to an electrophoretic paint filter with a filter residue removal function. The electrophoretic paint filter comprises a hollow cylinder, feeding devices and discharge devices arranged in the hollow cylinder at intervals and a filter between each adjacent feeding device and discharge device, each one of the feeding device comprises a vertical feeding pipe and an overflow prevention cover for preventing upward overflow of a filtrate, the overflow prevention cover is communicated with the vertical feeding pipe so that a filtrate feeding channel is formed, the edge of the overflow prevention cover is seal-connected to the inner wall of the hollow cylinder, each one of the discharge devices comprises a funnel-shaped outlet hopper, the bottom of the outlet hopper is connected to the top of the vertical feeding pipe of the next feeding device, the filter comprises a tapered filter plate, which is located below the overflow prevention cover and is coaxial with the vertical feeding pipes and a filter residue collection plate around the bottom edge of the tapered filter plate, and the bottom of the hollow cylinder is provided with a heating device. The electrophoretic paint filter has the advantages of good filtering effects, filter residue cleaning easiness and heating effects.

Description

technical field [0001] The invention belongs to the field of electrophoretic equipment, and in particular relates to an electrophoretic paint filter device with the function of cleaning filter residues. 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 m...

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
