FILTRATION MEMBER FOR SOLID-LIQUID SEPARATION |
摘要 |
The present invention relates to a filtration member (1) which is mainly used in a layered filter for forming a filter cake. A layer-settling structure comprises an optional metallic material and includes a plurality of thin openings (3). In order to improve the layer-settling process, the settling structure comprises a thin plate (2) or a film in which openings (3) are formed during the formation of expanded metal, wherein said openings are further bent so as to obtain slots of a predetermined width (B). The expanded metal then recovers its initial shape under a mechanical action so as to form slots with a given width. The openings (3) have a slightly conical shape which is widening in the flow direction. |
