Description

[Detailed description of the invention] As shown in Figs. 1 to 3, a conventional air filter has a material A formed by bending a large number of layered surface members a, a, etc. in a zigzag pattern into a frame. death,
A separator B having a large number of bent edges b, b... formed in a zigzag pattern is inserted into the space c between the adjacent surface members a of the material A, and and the adjacent separators B and B,
Bent edges b, b..., in contact with both side surfaces of the surface member a
b, b..., as clearly shown in the third figure, are arranged in a parallel relationship with their positions shifted in the vertical direction. When a large amount of air to be treated flows into the space c from the direction shown, each bent edge b of the separator B is pressed by the strong wind pressure. However, since there is no bent edge b on the opposite side of the surface member a of the material A that faces each bent edge b that is pressed, the surface member a has a dogleg shape on the opposite side due to the bent edges b. As a result, the material A as a whole is deformed into a wavy cross section at each surface member a, as shown in FIG. 4, and the pack strength of material B is weakened, resulting in a decrease in air filter characteristics and durability.

In order to improve this, the separators B and B adjacent to each other with the surface member a interposed therebetween are arranged in vertical positions at the bent edges b, b..., b, b... that contact both side surfaces of the surface member a. It is conceivable to arrange them in a parallel relationship that does not shift, that is, to align on the same line in the horizontal direction, but in this arrangement, the zigzag-shaped separator B is inserted into the space C of the material A. Not only is the operation extremely troublesome, but there is also the drawback that during use, the bent edge b easily deviates from its original position and is displaced into an undesirable vertically shifted position as described above. The present invention takes the above points into consideration, and provides an air filter that eliminates the above-mentioned conventional disadvantages and can stably maintain support from both sides of the material face member over a long period of time.
A large number of layered surface members 2 are arranged in a zigzag pattern within the frame 1.
A, 2a, .
In an air filter comprising a separator 4 bent so as to have a..., the material 2
The separators 4, 4 adjacent to each other via each surface member 2a are arranged in a relationship that intersects each other at bending lines 4a, 4a..., 4a, 4a... that contact both surfaces of the surface member 2a. .

An example of implementing the present invention will be described with reference to FIGS. 5 to 7. 1 is a solid metal rectangular frame 1, and 2 is a zigzag-shaped multi-layered surface member 2 inside the frame 1.
A, 2a, etc. are bent and housed in a material made of glass fiber, etc., and in each space 3 between each adjacent surface member 2a, 2a of the material 1, a large number of triangular cross sections are arranged in a zigzag pattern. A separator 4 made of aluminum, paper, etc., bent to have chevron-shaped bent edges 4a, 4a, etc., is inserted, respectively.
As shown in FIG. 7, the zigzag-shaped separator 4 is made by bending a rectangular separator element in a zigzag shape by appropriately tilting the separator element in advance with respect to the center axis in the width direction, thereby forming a large number of inclined bent edges 4a, 4a... When this is inserted into the space 3 according to the conventional method, as shown in FIGS.
The separators 4 disposed at a, 4a, . . . are automatically obtained. 5 shows a large number of parallel inclined air flow passages formed by the zigzag curved surface of the separator 4.

Thus, according to the present invention, a large number of such separators 4 are prepared and inserted into each space 3 between a large number of zigzag-shaped surface members 2a, 2a... of the material 1. Adjacent separators 4, 4 are arranged on both sides of the surface member 2a in such a manner that a large number of parallel inclined bent edges 4a, 4a, . When inserted into the spaces 3, 3, as shown in FIG. 6 in particular, a large number of bent edges 4a, 4a, which sandwich the surface member 2a and come into contact with it in a mutually obliquely intersecting relationship, are formed. , 4a, 4a... is obtained. Therefore, according to this, each surface member 2a has a large number of mutually intersecting bent edges 4a, 4a..., 4a, 4a...
A product is obtained in which both sides are sandwiched by a large number of intersecting portions 6, 6, . . . . Therefore, if a large amount of air enters the air filter during use,
The bent edges 4a, 4a..., 4 that intersect with each other at an angle
Each of the surface members 2a is held across its entire surface by the numerous intersections 6, 6, . Because of the intersecting relationship, plane member 2 is always
The clamping by the intersecting portions of a is not lost, and the conventional fear that the surface member 2a is displaced toward the other by the bent edge of one separator is completely eliminated, and the surface member 2a can be kept good and stable for a long period of time. can be maintained in the same state.

In this way, according to the present invention, a large number of surface members 2a bent in a zigzag shape housed within the frame 1...
In an air filter of the type in which a separator 4 is inserted into each space 3 of a material 2 having
Both separators 4, 4 inserted on both sides of the surface member 2a are bent edges 4a, 4a...,
4a, 4a... are disposed in such a manner that they intersect with each other, so that the surface member 2a is always held stably by being held from both sides at the many intersections 6, 6... It has the effect of maintaining a good and stable state over a long period of time.
