Abstract:
A membrane electrode device for electrodeposition coating comprising:an electrode;a tubular membrane assembly;a bottom end cap;a top end cap;a means for supplying wash fluid into said bottom end cap; anda means for supporting said top end cap,said tubular membrane assembly comprising a selectively permeable membrane,said electrode is surrounded along its axis by said tubular membrane assembly,said bottom end cap comprising a means for engaging said tubular membrane assembly, said electrode, and a means for creating turbulence in said wash fluid introduced into said bottom end cap,said top end cap comprising an outlet means for said wash fluid and a means for receiving said membrane assembly such that said electrode can pass through the center of said top end cap, through the center of said tubular membrane assembly, as received within said top end cap, and extend downwardly into the bottom end cap,said means for supplying said wash fluid oriented so as to introduce said wash fluid into the bottom end cap,said means for supporting said top end cap preventing said top end cap from deforming said tubular membrane assembly, andwhen assembled, wash fluid introduced into the bottom end cap circulates through the means for creating turbulence and flows upward along the electrode and between said electrode and said membrane, to exit through said outlet for wash fluid.
