Abstract

The invention discloses a water-based ink filtration system and a filtration method, which relate to the technical field of ink manufacturing and aim to solve the problem of low cost and high filtration efficiency of the current water-based ink. Feed pipe, feed pipe, ink tank one and ink tank two, the filter includes a filter capsule provided with a liquid inlet, a liquid outlet and a filter element in the filter capsule, and the liquid inlet is connected by a feed pipe Ink tank one, the liquid outlet is connected to ink tank two through a discharge pipe (57), and the test end of the pressure gauge extends into the liquid inlet of the filter capsule; during filtration, the peristaltic pump is arranged on the feed pipe , when cleaning the filter element, the peristaltic pump is arranged on the discharge pipe (57). The invention adopts a stepping peristaltic pump plus a single filter capsule and a single filter element to soak and reverse-circulate the used filter element, and can filter the ink stably and reliably, improving the quality stability of the filtered ink.

Description

technical field [0001] The invention relates to the technical field of ink manufacturing, and more particularly, to a water-based ink filtering system and a water-based ink filtering method. Background technique [0002] The production of water-based ink generally consists of three parts: dissolving, dispersing, filtering and canning of dyes. The current filtration system is generally composed of a pneumatic diaphragm pump plus 2-5 filter capsules and 2-5 grades of filter elements, with high filtration efficiency and low cost. During the filtration process, the consumption of the filter element is relatively large, and the filter element may be blocked after one end of the filtration, resulting in the subsequent filtration of the output ink unable to meet the set requirements, resulting in poor quality stability of the output ink, affecting the subsequent printing process. [0003] Therefore, it is necessary to propose a new solution to solve this problem. SUMMARY OF THE ...
