Abstract
Apparatus suitable for the removal of solids from printing ink, among other liquids. Adopted to this end are a magnet assembly and a filter assembly. Comprising a row of permanent magnets enclosed in an elongated housing, the magnet assembly is suspended concentrically in a first liquid chamber of cylindrical shape having an inlet port at its bottom end and an overflow port at its top end. The ink is freed of magnetic solid particles while flowing upwardly through the first liquid chamber, and then overflows into a second liquid chamber in which the filter assembly is suspended centrally. The filter assembly comprises a multiplicity of flat rings or apertured discs, alternating with spacers, stacked on a core rod. Nonmagnetic solid particles still remaining in the ink are removed as it flows into the filter assembly. The cleaned ink leaves the apparatus through an outlet port in communication with the interior of the filter assembly. The solids captured by the filter assembly can be scraped off by revolving the rings or discs with the core rod.
