Description

Filter disc for ink production Technical Field The application relates to the technical field of ink production and filtration, in particular to a filter disc for ink production. Background In the ink production process, the filtration is one of the key steps of ensuring the ink quality, the traditional filtration mode mainly depends on filter paper, the filter paper ensures the purity of the ink by intercepting impurities, however, along with the expansion of the ink production scale and the improvement of the production efficiency, a filtration system needs to continuously run for a long time, the durability of the filter paper is required to be higher, the filter paper is easy to be broken under the action of unidirectional pressure in the long-time use process of the traditional filtration technology, the filtration effect is reduced, and even the impurities can be re-entered into the ink to influence the product quality. In order to solve the problem that the filter paper is broken in the filtering process, the prior art generally adopts the following methods, firstly, the thickness or strength of the filter paper is increased, the compression resistance of the filter paper is improved by selecting more durable filter paper materials, secondly, a plurality of layers of filter paper are arranged in a filtering device, the pressure is dispersed by layered filtration, thirdly, an auxiliary supporting structure such as a grid or a bracket is adopted to provide additional supporting force for the filter paper, however, the thickness or the plurality of layers of filter paper can improve the compression resistance, but the filtering efficiency is reduced, the ink passing performance is poor, and the design of the auxiliary supporting structure is difficult to find balance between the bearing force and the ink passing performance, so that the problems of blockage or insufficient supporting easily occur. Therefore, the main defect of the prior art is that the bearing capacity of the filter paper and the trafficability of the ink cannot be considered simultaneously, the filter efficiency is reduced by increasing the thickness of the filter paper or by increasing the number of layers of the filter paper, the design of the auxiliary supporting structure is often too complex and difficult to be widely applied in practical production, and in addition, the prior art lacks a simple and effective solution, can stably protect the filter paper from being broken in the long-time use process, and simultaneously maintains the efficient filtering performance.
