An electrophoretic paint filter

Abstract

The invention belongs to the field of electrophoresis equipment, and particularly relates to an electrophoresis paint filtering device. The electrophoresis paint filtering device comprises a hollow barrel, a plurality of feeding devices and discharging devices which are arranged at intervals in the hollow barrel, and filtering device bodies positioned among the feeding devices and the discharging devices, wherein each feeding device comprises a vertical feeding pipe, and a taper overflowing stopping cover preventing filtrate from overflowing upward; each taper overflowing stopping cover is communicated with the corresponding vertical feeding pipe, so as to form a filtrate feeding channel; the edge of each taper overflowing stopping cover is connected with the inner wall of the hollow barrel in a sealing manner; each discharging device comprises a funnel-shaped discharging hopper body; the bottom of each discharging hopper body is connected with the top of the corresponding vertical feeding pipe of the next feeding device; each filtering device body comprises a truncated cone-shaped filtering plate positioned below the corresponding overflowing stopping cover and arranged coaxially to the corresponding vertical feeding pipe, and a filter residue collecting plate surrounding the bottom edge of the truncated cone-shaped filtering plate. The hollow barrel is further provided with a heating device. The electrophoresis paint filtering device has the advantages of being good in filtering effect and capable of heating.

Description

technical field [0001] The invention belongs to the field of electrophoretic equipment, and in particular relates to an 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 existing elect...

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
