Abstract

본 발명은 특별한 적층구조에 의해 여과 정밀도 및 여과 효율을 개선시킨 자성물질 여과용 다층 카트리지 필터에 관한 것이다.The present invention relates to a multilayer cartridge filter for magnetic material filtration which improves filtration accuracy and filtration efficiency by a special lamination structure.

본 발명에 따른 자성물질 여과용 다층 카트리지 필터는 다수의 통공을 갖는 코아위에 복수개의 여과층을 구비하여 이루어지는 다층 카트리지 필터에 있어서, 상기 코아위에 내층으로부터 장섬유 부직포층, 제1방적사권취층, 무기질 섬유 부직포층 및 제2방적사 귄취층을 순차적으로 적층 권취한 것을 특징으로 한다. 상기 제1방적사층은 화학섬유 부직포층으로 대체될 수도 있다.The multi-layer cartridge filter for magnetic material filtration according to the present invention is a multi-layer cartridge filter comprising a plurality of filter layers on a core having a plurality of through-holes, wherein the long fibers nonwoven fabric layer, the first spun yarn winding layer, The fibrous nonwoven fabric layer and the second yarn yarn winding layer are sequentially laminated and wound up. The first yarn layer may be replaced with a chemical fiber nonwoven fabric layer.

본 발명에 따르면 여과 정밀도가 높고 콜로이드 응집물 분쇄기능이 우수하여 자성물질을 함유한 용액의 여과에 적합한 자성물질 여과용 다층 카트리지 필터가 제공되는 효과가 있다.According to the present invention, it is possible to provide a multilayer cartridge filter for magnetic material filtration, which is suitable for filtration of a solution containing a magnetic substance with high filtration accuracy and excellent pulverizing ability of colloid aggregates.
