A multifunctional electrophoretic paint pretreatment device

Abstract

The invention belongs to the field of electrophoretic equipment, and in particular, relates to a multifunctional electrophoretic paint pretreatment device. The multifunctional electrophoretic paint pretreatment device comprises a hollow cylinder, multiple feeding devices and discharge devices alternatively arranged in the hollow cylinder, and filter devices positioned between the feeding devices and the discharge devices close to each other; the feeding devices include vertical feeding pipes, and overflowing stop covers for preventing filtrate from upwards overflowing; the overflowing stop covers are communicated with the vertical feeding pipes to form filtrate feeding channels; the edges of the overflowing stop covers are tightly connected with the inner wall of the hollow cylinder; the discharge devices include funnel-shaped discharge hopper bodies; the bottoms of the discharge hopper bodies are connected with the tops of the vertical feeding pipes of the next feeding devices; and the filter devices include conical filter plates positioned below the overflowing stop covers and coaxially arranged with the vertical feeding pipes, and filter slag collecting plates surrounding the bottom edges of the conical filter plates. A water bath heating device is arranged at the bottom of the hollow cylinder. The electrophoretic paint pretreatment device has the advantages of good filter effect and capability of heating.

Description

technical field [0001] The invention belongs to the field of electrophoretic equipment, and in particular relates to a multifunctional 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
