Title:
WASTE LIQUID REGENERATOR OF PRINTING MACHINE AND METHOD FOR REGENERATING WASTE LIQUID
Document Type and Number:
WIPO Patent Application WO/2004/060816
Kind Code:
A1
Abstract:
A container (2) being supplied with waste liquid (11) containing ink pigment , water and cleaning liquid used in a printing machine is sectioned into a first chamber (a) and second chambers (b, c) by disposing metal electrode plates (30a, 30b) capable of circulating the waste liquid (11) in the container (2). A high voltage is applied from a high voltage source (7) to the metal electrode plates (30a, 30b) and the first chamber (a) is connected with an earth electrode (20) thus generating an electrostatic field between the metal electrode plates (30a, 30b) and the earth electrode (20). Water and ink pigment are aggregated electrostatically from the waste liquid (11) utilizing electrophoresis of the ink pigment caused by the electrostatic field thus separating the waste liquid in the first chamber (a) into cleaning liquid, water and ink pigment.
