Cartridge filter suitable for filtering soft impurities and filtering system

Abstract

The invention discloses a cartridge filter suitable for filtering soft impurities. The cartridge filter comprises a support, wherein a cylinder body is fixed on the support; a cylinder top is detachably fixed at the top of the cylinder body; a pressure gauge port and an exhaust port are formed in the cylinder top; a center rod is fixed in the cylinder body; a filter element gland is arranged at the top of the center rod; and the center rod is sleeved with the filter element. The cartridge filter further comprises a liquid inlet pipe and a liquid outlet pipe, wherein the liquid inlet pipe penetrates through a cylinder bottom to communicate with the interior of the cylinder body and the exterior of filter elements, and the liquid outlet pipe penetrates through the cylinder bottom to communicate with the interior of the filter element; the cylinder bottom is of a plane structure, and sealing gaskets are arranged at two ends of the filter element; and the filter elements are elastic filterelements or rigid filter elements. According to the invention, by researching the influence of the filtering power, a filtering medium and filtering precision on the interception of soft substances,utilization of the proper filter elements as the filtering medium and optimization of the filtering power and a filtering mode, the purpose of improving the cleanliness of coating liquid is achieved.

Description

technical field [0001] The invention belongs to the technical field of coating fluid filtration, and in particular relates to a cartridge filter and a filtration system suitable for filtering soft impurities. Background technique [0002] With the development and application of coating technology, there are more and more functional coating liquids, and in the preparation process of functional coating liquids, there are not only useful granular substances or soft substances, but also useless Impurities, these impurities include both incompressible solid particles and soft substances with certain elasticity. The incompressible solid particles can be removed by conventional filters and filtration methods, but the removal of soft impurities is difficult. It is necessary to keep useful software and remove useless software. At the same time, the defoaming technology of the coating liquid in the coating process can only be better realized by virtue of a certain filter structure. ...
