By forcibly fitting the filtration sponge body into a case with a specific shape, that is, a case whose diameter gradually decreases from the inlet to the filtered air outlet, A gas filtration material in which a sponge body is gradually compressed is known from Japanese Utility Model Publication No. 18535/1983, and a plurality of felt filter media made of laminated fibers are arranged so that the lamination direction surfaces are mutually disposed on the outer periphery of a porous cylinder. A cylindrical filter medium was developed in 1973, in which the filter medium was arranged in a radial direction in close contact with the cylindrical filter medium, and this was covered with a bag body, and each filter medium was gradually compressed from the outside to the inside in this position.
It is known from No. 146905 (Utility Model Publication No. 50-92466).

For example, in the case of the former, in order to obtain the degree of compression that corresponds to the location of the filter sponge body, it is necessary to prepare a case with a corresponding shape, and in the case of the latter. teeth,
In some cases, a porous cylinder or bag is required, or a large number of filter media are arranged with their lamination direction surfaces in close contact with each other, that is, with the direction perpendicular to the lamination direction facing in the radial direction, and this is used as a bag. The manufacturing process is complicated because the density is increased from the outside to the inside of the filter medium by wrapping the bag with a porous cylinder and bonding both ends of the bag to the end faces of the porous cylinder.

An example of the implementation of the present invention will be described with reference to the accompanying drawings. A is a nonwoven fabric that is a type of fiber aggregate, and a laminate B is obtained by laminating a large number of nonwoven fabrics. A vertical hole C is bored in the center of this laminate B. Reference numeral D denotes an inclined pressing plate having a funnel shape, and the portion corresponding to the vertical hole C of the laminate B is a circular hole, but the circular hole does not have to be provided at all times. It is convenient if the diameter of the inclined pressing plate D is equal to the diameter of the laminate B, but this is not necessarily the case. An inclined pressing plate D is placed on the upper surface of the laminate B, and by pressing the inclined pressing plate D, the laminate B changes in fiber accumulation density from coarse to dense from the circumferential surface E to the vertical hole C. It will be changed to. In this way, filter F is obtained. According to this filter F, the air containing dust is removed from the circumferential surface E of the filter F.
The dust that enters the air, exits through the vertical hole C of the filter F, and is further removed upward or downward, and at this time, the large particles of dust in the air are removed from the area near the air inlet side, which is the circumferential surface E of the filter. Particles with small diameters are captured in area Z near the air outlet side, which is vertical hole C of the filter, and particles with intermediate sizes are captured in area Y between them. be done. Although the case where a laminate of nonwoven fabric is used as the fiber aggregate and a pressing plate consisting of one linear inclined surface is used as a means for changing the fiber accumulation density has been described above, there are various other cases as well. A few examples will be described below, but it is obvious that the present invention is not limited to these explanations and is free as long as it does not depart from the spirit of the present invention.

与えられる。 The fiber aggregate used in the present invention is not limited to the above-mentioned nonwoven fabric laminate, but may also be a single lump such as a sponge, felt, fiber lump, etc., which can be pressed. This provides a variation in the fiber density of the single mass portion.

体を用意する必要がある。 The fiber aggregate, which is the filtration material of the present invention, may be used in such a way that the fiber aggregate density may be changed by pressing with a pressing plate as explained above, but apart from this, the fiber aggregate density as shown in FIG. As an example shown in A and B, a fiber aggregate with a relatively uniform fiber density is pressed so that each part has a preset fiber density, and this pressed state is fixed and molded. The resulting aggregate can also be used as a filtration material. In this case, since it can only be applied within the range of the dust particle size distribution assumed in advance, it is unlikely that it will be as effective as expected for different particle size distributions. Therefore, it is necessary to prepare several types of aggregates with different distributions of fiber accumulation densities.

体に適用できることも当然である。 In addition, when the fiber aggregate that is the filtration material is pressed, in order to make the fiber accumulation density change linearly from the gas inlet side to the outlet side of the fiber aggregate, it is necessary to It is sufficient to press with a plate whose vertical cross section from the side to the outlet side is a straight line. The pressing plate may be formed of two or more straight lines. Therefore, in the latter case, the longitudinal section of the pressing plate is expressed in a sawtooth shape or a shape similar to it. The press plate is not limited to a press plate whose vertical cross section is a straight line, but may be a curved line, or may have an arbitrary curved line. Although the above explanation has been made regarding a filter for automobile engines, it can be used not only for general household use but also for air filtration in hospitals, factories, etc., and can also be applied to gases other than air. .

へ連続的に変化している。 Next, an example of the manufacturing method for obtaining the filtration material of the present invention is shown in which 30% (weight ratio) of polyester fibers with a single yarn fineness of 6 denier and a fiber length of 51 mm are used. A mixture of 30% (weight ratio) of 51 mm polyester fiber and 40% (weight ratio) of rayon fiber with a single yarn fineness of 3 denier and a fiber length of 51 mm was applied to a random web to form a web with a weight of 80 g/m 2 . This was then bonded with an acrylic ester adhesive so that the solid content was 20 g/m 2 to produce a nonwoven fabric with a product weight of 100 g/m 2 and a thickness of 0.9 mm. The apparent density of this nonwoven fabric is 0.111.
This nonwoven fabric is punched into a donut shape with an outer diameter of 300 mm and an inner diameter of 150 mm, and 70 sheets of this are laminated concentrically to form a nonwoven laminated donut plate. The bottom surface of the donut is a flat donut plate, but the top surface has a deformed donut-shaped disk with an inclination of about 10 degrees toward the center of the circle. Place the non-woven laminated donut plate between the flat donut plate on the bottom surface and fix it under pressure so that the interval between the upper and lower plates on the outer diameter part is 58 mm and the interval on the inner diameter part is 45 mm, I made a filter element. In this filter element, the apparent density of the nonwoven laminate at the outer diameter part is 0.121, and at the inner diameter part it is 0.156. During the air flow path length of approximately 75 mm from the outer diameter part to the inner diameter part, the density varies from sparse to sparse. Continuously changing to denser.
