Abstract

The invention discloses a water-based ink filtering system and a filtering method, relates to the technical field of ink manufacturing, and aims to solve the problems of low filtering efficiency and high cost of current water-based ink. The water-based ink filtering system is characterized by comprising a filter, a peristaltic pump, a pressure gauge, a feeding pipe, a discharging pipe, an ink tank I and an ink tank II. The filter comprises a filter bag and a filter element, the filter bag is provided with a liquid inlet and a liquid outlet, the filter element is arranged in the filter bag, the liquid inlet is connected with the ink tank I through a liquid inlet pipe, the liquid outlet is connected with the ink tank II through a liquid outlet pipe, and the testing end of the pressure gauge extends into the liquid inlet of the filter bag. During filtering, the peristaltic pump is arranged on the liquid inlet pipe, and during cleaning of the filter element, the peristaltic pump is arranged on the liquid outlet pipe. The stepping peristaltic pump, the single filter bag and the single filter element are adopted, the used filter element is soaked and subjected to reverse circulation washing, ink can be stably and reliably filtered, and the quality stability of the filtered ink is improved.

Description

technical field [0001] The invention relates to the technical field of ink manufacture, more specifically, it relates to a water-based ink filtration system, and also relates to a water-based ink filtration method. Background technique [0002] The production of water-based ink generally consists of three parts: dissolving and dispersing dyes and chemicals, filtering and canning. The current filtration system is generally composed of a pneumatic diaphragm pump plus 2-5 filter capsules and 2-5 filter elements, with high filtration efficiency and low cost. The filter element is consumed during the filtration process, and the filter element may become clogged after one end of filtration, resulting in the failure of the subsequent filtered output ink to meet the set requirements, resulting in poor quality stability of the output ink, and affecting subsequent printing processing. [0003] Therefore, a new solution needs to be proposed to solve this problem. Contents of the inv...
