Technical Field

[0001] This utility model relates to the field of filtration equipment technology, and in particular to a portable electrophoretic paint filtration system. Background Technology

[0002] Workpiece shrinkage has always been a problem in electrophoresis. Electrophoresis manufacturers and downstream customers need to invest a considerable amount of money to purchase heavy equipment to solve the problem of shrinkage in the bath solution.

[0003] Currently, the most commonly used equipment on the market is the "diatomaceous earth thin-shaft / plate filter." However, this type of equipment has the following limitations: 1. Although it has been continuously improved, it has not yet met the needs of the domestic industry in terms of funding and equipment contribution; 2. This equipment is expensive and suitable for large-scale electrophoretic coating industries. Therefore, there is an urgent need to develop a "small but sophisticated" filtration system suitable for the electrophoretic coating industry. Utility Model Content
