Abstract
The invention relates to a filter having a layer which is permeable to a medium to be filtered, comprising at least one nonwoven part, wherein the nonwoven part withstands higher mechanical loads. According to the invention the layer comprises, in addition to the nonwoven part, at least one sheet-like support part connected to at least one sub-region of at least one side of the nonwoven part.
Claims15
A filter system having at least one layer that is permeable for a medium to be filtered (3), comprising at least one nonwoven part and at least one support part (5) made of expanded metal or perforated sheet metal, which is welded or sintered to at least a partial region of at least one side of the nonwoven part, and at least one further layer (1, 2, 4), wherein the support part (5) is disposed on the side of the nonwoven part that is directed away from supporting layer (1) or toward the same.
The filter system according to any one of the previous claims, characterized in that the support part (5) and/or the nonwoven part is/are constituted of a material that is selected from the group consisting of iron- and/or nickel-containing alloys.
The filter system according to any one of the previous claims, characterized in that the nonwoven part is a nonwoven part including oriented and/or randomly laid-down fibers.
The filter system according to any one of the previous claims, characterized in that the same further includes at least one intermediate layer (2), preferably made of expanded metal, and/or at least one outer layer (4) constituting a clamping jacket.
The filter system according to any one of the previous claims, characterized in that the supporting layer (1) is configured as a perforated jacket.
A use of a filter system having at least one layer that is permeable for a medium that is to be filtered (3) comprising at least one nonwoven part and at least one support part (5) of expanded metal or perforated sheet metal, which is welded or sintered to at least a partial region of at least one side of the nonwoven part inside a device for the filtration of viscose, or a method for the filtration of viscose.
