Abstract
A flame trap filter including a grid structure, wherein the grid structure determines grid openings which are bordered by intersecting strip sections, and/or wherein the grid structure is formed by a laid scrim. A method for producing a grid structure of a flame trap filter includes the step of allowing a substance to solidify on a substrate, in order to form at least one strip section of the grid structure. Alternatively or in addition, the method includes the step of compressing a material for the flame trap filter or a semi-finished product of the flame trap filter at points, e.g. by mechanically deforming the material or the semi-finished product, in order to form at least one strip section of the grid structure.
Claims15
A flame trap filter, comprising:
- a plurality of grid structures, that define a body, wherein at least one grid structure of the plurality of grid structures is manufactured by laser cutting or stamping from a foil or a sheet material, each of the plurality of grid structures, comprising:
- a first layer of webs orientated in a first direction;
- and
- a second layer of webs orientated in a second direction transverse to the first direction such that a plurality of grid openings are formed, and
- wherein the plurality of grid structures allow fluid flow in an axial direction with respect to the body as well as two different transverse directions with respect to each other and the axial direction.
A flame trap filter, comprising:
- a plurality of grid structures, that define a body, each grid structure of the plurality of grid structures is formed of a laid scrim, comprising:
- a first layer of webs orientated in a first direction;
- and
- a second layer of webs orientated in a second direction transverse to the first direction such that a plurality of grid openings are formed, wherein the plurality of grid structures allow fluid flow in an axial direction with respect to the body as well as two different transverse directions with respect to each other and the axial direction, and
- wherein the first layer of webs and the second layer of webs are manufactured by solidification of a substance on a substrate.
A method for manufacturing a flame trap filter, the flame trap filter having a plurality of grid structures that define a body, wherein each grid structure of the plurality of grid structures is formed of a laid scrim, comprising:
- a first layer of webs orientated in a first direction;
- and a second layer of webs orientated in a second direction transverse to the first direction such that a plurality of grid openings are formed, wherein the plurality of grid structures allow fluid flow in an axial direction with respect to the body as well as two different transverse directions with respect to each other and the axial direction, and
- wherein the first layer of webs and the second layer of webs are formed from a substance that is solidified on a substrate,
- and/or wherein a material for the flame trap filter or a semi-finished product of the flame trap filter is compressed at locations to form one of the plurality of grid structures.
