Definitions
- the present invention relates to a filter member.
- a filter member in which a nonwoven fabric is formed in a cylindrical shape so as to capture impurities such as a nonwoven fabric is used in a part of the pipe line.
- a filter member 50 that folds the nonwoven fabric in the circumferential direction as shown in FIG. This is a method of increasing the surface area by folding a large circumferential nonwoven fabric in the circumferential direction.
- the density of the non-woven fabric is concentrated at the central portion 51, there is a problem that the flow of the fluid is hindered and the life is shortened.
- Patent Document 1 proposes a filter member 60 that increases a surface area by preparing a long cylindrical nonwoven fabric in the longitudinal direction and shrinking it in the longitudinal direction.
- the non-woven fabric does not have a high density density in the center of the entire circumference, and it is dispersed in the circumferential direction. It is more advantageous than the folding method.
- this method has the following problems.
- FIG. 7 is a view of the filter member 60 as viewed from the direction along the central axis CL of FIG.
- the vertex 30 coincides with the vertex 34, and similarly, for example, the vertex 31 and the vertex 35, the vertex 32 and the vertex 36, and the vertex 40 and the vertex 44 are The vertex 41 and the vertex 45 coincide with each other.
- the folding region A and the folding region B of adjacent filters completely overlap.
- the overlapping of the folding regions continues along the central axis CL.
- the region X has the largest overlap. In the overlapping portion, there are large portions where the density of the nonwoven fabric is high, and the fluid flow is still hindered.
- the outer diameter and inner diameter of the cylindrical filter member are basically fixed by the peripheral length.
- the inner diameter at this time is 1 ⁇ 2 of the outer diameter, which is a restriction that can be selected as the inner diameter. That is, in the case of this method, there is a problem that the inner diameter cannot be selected once the outer shape is determined.
- a valley fold is formed between adjacent mountain folds, In one polygon, the mountain fold and the valley fold are connected at one vertex, and the valley fold is connected to the vertex next to the vertex in the other polygon to which the mountain fold is connected.
- the valley fold is formed obliquely with respect to the central axis.
- the inner diameter can be selected without reducing the number of sides of the polygon.
- the external appearance of the filter member of this invention is shown.
- the cross section of the filter member of the present invention is shown.
- the relationship of the external appearance and cross section of the filter member of this invention is shown.
- the relationship of the adjacent cross section of the filter member of this invention is shown. It is the figure which showed the structure which increases the surface area of a filter member by folding a nonwoven fabric in the circumferential direction. It is the figure which showed the structure which folds a nonwoven fabric in a longitudinal direction and increases the surface area of a filter member. It is the figure which showed the structure which folds a nonwoven fabric in a longitudinal direction and increases the surface area of a filter member.
- FIG. 1 shows a filter member of the present invention.
- FIG. 2 is a cross-sectional view seen from the direction along the central axis CL of FIG.
- FIG. 3 shows the relationship between the appearance and the cross section of the filter member of the present invention.
- FIG. 4 shows the relationship between adjacent cross sections of the filter member of the present invention.
- the filter member 10 is formed by forming a nonwoven fabric in a cylindrical shape around the central axis.
- the filter member 10 is formed with m n-gonal cross-sections aligned in a direction along the central axis CL at intervals. That is, it is a filter member having a plurality of polygonal cross-sections of the same shape formed by forming a cylindrical nonwoven fabric having a central axis and arranging the nonwoven fabrics along the central axis at a predetermined interval.
- n 6 will be described, and a generalized case of an n-gon will be described taking a hexagon as an example.
- each side is formed by a mountain fold in a plane perpendicular to the central axis CL.
- each vertex of one polygon is connected with each vertex of the other polygon at a mountain fold part. That is, in FIGS. 1 and 2, for example, a hexagonal cross section formed by the vertex 11, vertex 12, vertex 13, vertex 14, vertex 15, and vertex 16 and a hexagonal cross section adjacent thereto (vertex 17, vertex 18, vertices 19, vertices 20%), One hexagonal vertex 11, vertex 12, vertex 13...
- Vertex 16 and the adjacent hexagonal vertex 17, vertex 18, vertex 19, vertex 20. are connected at the mountain fold 10a.
- the valley fold part 10b is formed between the adjacent mountain fold parts 10a among the adjacent mountain fold parts 10a.
- the mountain fold part 10a and the valley fold part 10b are connected at one vertex, for example, the vertex 11, and the valley fold part 10b is the vertex next to the vertex in the adjacent hexagon to which the mountain fold part 10a is connected. Connect to Thereby, the mountain fold part 10a and the valley fold part 10b are formed diagonally with respect to the central axis CL.
- the filter members 10 are adjacent to each other. It is possible to make the vertices of the overlapping area of the filters not coincide. That is, when the filter member 10 is folded in the axial direction of the filter member 10, the adjacent overlapping region formed by the vertex 11, the vertex 12, and the vertex 18 and the adjacent region formed by the vertex 11, the vertex 17, and the vertex 18.
- the overlapping area can prevent the vertex 12 and the vertex 17 from being completely coincident with each other.
- the mountain fold portion 10a and the valley fold portion 10b are positioned obliquely along the central axis CL, so that the adjacent regions Y are positioned rotationally symmetrical around the central axis CL. . Therefore, when the filter member 10 is folded in the axial direction of the central axis CL of the filter member 10, the overlapping area adjacent to the axial direction of the central axis CL is reduced to the amount of the area Z in the area Y.
- the overlapping of the folding regions shown in FIG. 7 of the prior art is greatly different from the aspect of being continuous along the central axis CL.
- the region X that overlaps adjacently in the folding region always has the same area along the central axis CL, and creates a region where the density of the nonwoven fabric is concentrated.
- the area adjacent to and overlapped in the axial direction of the central axis CL is reduced, for example, from the area Y to the area Z. As shown, the adjacent overlapping area is reduced.
- the filter member 10 is formed as a row (1, 2,..., P,... N) in which the apexes of the n-gon of each cross section are arranged in the direction along the center axis CL.
- a row (1, 2,..., P,...) In which the vertices are arranged in the direction along the central axis CL up to the n-th toward the row located next to the vertex located in the reference row as the first. ⁇ ⁇ N).
- i p 1 to m
- q 1 to n
- 3 and 4 for example, in the first section, i 1,1, i 1,2, i 1,3, ⁇ , i 1, q, ⁇ , i 1, n-1, i 1, n .
- hexagonal i 1,1, i 1,2, i 1,3, i 1,4, i 1,5, a i 1, 6.
- i p, 1 , i p, 2, i p, 3 , i p, 4 , i p, 5, i p, 6 are obtained.
- im , 1 , im , 2, im , 3 , im , 4 , im , 5, im , 6 are obtained.
- the filter member 10 has a twisted structure between the cross sections. That is, the mountain-folded portion 10a is formed such that each vertex is twisted about the central axis CL in one arbitrary cross section and another cross section adjacent thereto. A valley fold 10b is formed between the mountain folds 10a. Thereby, as above-mentioned, the mountain fold part 10a and the valley fold part 10b are formed diagonally with respect to the central axis CL.
- i m, 1 is i m-1, n and, i m, 2 and i m-1,1, i m, 3 and i m-1, 2, any vertex i m, 4 has im m-1,3 , im , 5 has im -1,4, and im , 6 has im m-1,5 .
- the amount of twisting of the twisting structure can be arbitrarily determined. The mountain fold may be reversed.
