WASTE LIQUID REGENERATION APPARATUS OF PRINTER

Japanese Patent JP2005305205

A

To provide a waste liquid regeneration apparatus with reduced manufacturing cost by proposing a simplified apparatus.

Positive and negative electrodes 4 and 3 are arranged on facing vertical walls of the waste liquid regeneration apparatus 1, and waste liquid containing ink pigment, water and washing liquid used in a printer is introduced into a waste liquid regeneration tank. Voltage is applied between the positive and negative electrodes 4 and 3, the waste liquid is treated by using an electrostatic field, the ink pigment is induced to the negative electrode, to settle coagulated water to the bottom of the regeneration apparatus 1. Washing liquid with a specific gravity lighter than water is separated as supernatant to regenerate the washing liquid from the waste liquid. Electric insulators 5 are provided above the electrodes 3 and 4 of the vertical walls, and the level of the waste liquid is adjusted to the position of the insulators.
