The present invention relates to a member used for a filter for filtering the fine dust or foreign matter contained in the fluid (gas or fluid), in particular, when the pressure of the fluid is large, the filter medium of the filter is deformed by the fluid pressure to improve the filtration performance The present invention relates to a fixture configured to stably support the filter medium to prevent falling.

1 is a perspective view showing a typical pleated filter filter medium, Figure 2 is a cross-sectional view showing a problem of the pleated filter filter medium shown in FIG.

As shown in FIG. 1, in the general pleated filter 1, a pleated filter medium 3 is positioned inside, and a frame 5 is fixed around the filter medium 3. As the fluid passes through the filter medium 3, fine dust or foreign matter contained in the fluid is filtered by the filter medium 3.

In such a pleated filter 1, the reason why the filter medium 3 is made corrugated is to enlarge the unit area. By pleating the filter medium 3, the filter medium 3 having a larger area than the area partitioned by the frame 5 can be provided, thereby reducing the amount of filtration per unit area of the filter medium 3 to thereby filter performance. To improve.

Such filter media 3 are generally porous media as materials such as filter cloth, paper, pulp, sponge, and the like. Most of these porous media are characterized by being flexible. Therefore, the frame 5 supporting the filter medium 3 is fixed to the periphery of the pleated filter medium 3 to stably support the periphery of the filter medium 3, but the center of the filter medium 3 is dependent on the filter material 3 itself rigidity. Because of this, it is easily deformed even at a small pressure.

That is, as shown in FIG. 2, when the fluid inflow is large and the fluid pressure per unit area of the filter medium 3 is increased, the pleated filter medium 3 is deformed. Specifically, some acids 7 and 7 of the pleated filter medium 3 are constricted, and the valleys 9 are relatively deformed in the form of opening. As the fluid continuously flows in the deformed state as described above, the filter medium 3 maintains the deformed form. If the pleated filter medium 3 is maintained in the deformed form rather than the original form, the fluid is confined. A lot of fluid flows into the valleys 9 which are relatively wider rather than entering.

Then, the amount of filtration per unit area of the filter medium 3 on the side where the fluid flows in large becomes large, and the effect of filtration is inferior.

In particular, in the deformed state, the wider the valley 9, the more filtered fine dust or foreign matter is collected and the filtration performance is further reduced, thereby shortening the filter replacement time.

The present invention is designed to solve the problems of the prior art as described above, by supporting the filter medium to maintain the original form even under the pressure of the fluid, pleats for supporting the filter medium to maximize the performance of the filter medium It is an object of the present invention to provide a fixture for a filter medium filter.

In the following, with reference to the accompanying drawings, preferred embodiments of the fixture for the pleated filter filter medium according to the present invention will be described in detail.

[First Embodiment]

3 is a perspective view showing a pleated filter filter medium fixture and a pleated filter corresponding thereto according to the first embodiment of the present invention, Figure 4 is a combined state of the fixing portion and the filter shown in FIG. It is sectional drawing shown.

As shown in FIGS. 3 and 4, the pleated filter 10 has a pleated filter medium 13 and a frame 15 is fixed around the filter medium 13. The fastener 100 according to the present invention faces the filter medium 13 and the support plate 110 is fixed at both ends to the frame 15, and the filter medium is separated at a predetermined interval in the longitudinal direction of the support plate 110. 13 includes a plurality of protrusions 120 respectively inserted into the valleys 19. On the other hand, a groove 130 is formed in the protrusion 120, the groove 130 compensates for the reduction of the filtration area generated as the filter medium 13 contacts the protrusion 120 by air pressure.

Hereinafter, the fixture for the pleated filter filter material configured as described above will be described in detail.

The support plate 110 of the fixture 100 has a band structure in which both ends thereof are fixed to the frame 15. When both ends of the support plate 110 are fixed to the frame 15 by bolts or the like, the support plate 110 is formed of a filter material 13. Is located opposite to).

On the other hand, a plurality of protrusions 120 are fixed to the support plate 110 in a row, the interval between the protrusions 120 and the protrusions 120 between the bone 19 and the bone 19 of the filter medium 13. Is equal to the pitch (P in FIG. 2). Therefore, when the support plate 110 is fixed to the frame 15, the protrusions 120 fixed to the support plate 110 are positioned in the state of being inserted into each valley 19 of the filter medium 13, respectively.

As such, the protrusion 120 is inserted into the bone 19 so that the fluid may collide with the filter medium 13 to generate pressure, so that the filter medium 13 is supported by the protrusion 120, thereby allowing the filter medium 13 to be subjected to the pressure. Will remain in its original form. That is, the deformation of the extent to which the acid 17 and the acid 17 of the filter medium 13 are constricted as in the prior art does not occur.

Here, the fixture 100 is preferably installed in the direction in which the fluid is discharged after passing through the filter medium (13).

On the other hand, as the protrusions 120 support the filter medium 13, the filter medium 13 receives air pressure, and thus the protrusions 120 and a part of the filter medium 13 come into contact with each other. As the protrusions 120 and the filter medium 13 come into contact with each other, the filtration area through which the fluid can pass through the filter medium 13 is reduced. In a portion corresponding to 130, fluid may pass through the filter medium 13. Thus, the formation of the projections 120 compensates for the reduced filtration area.

In addition, since the protrusions 120 are inserted into the valleys 19 of the filter medium 13, the fluid passing through the filter medium 13 collides with the protrusions 120 and moves out of the protrusions 120 along the grooves 130. Induced.

In this way, the fluid passing through the filter medium 13 is guided along the groove 130 to be smoothly discharged out of the protrusion 120, thereby lowering the pressure inside the valley 19 of the filter medium 13, thereby filtering the filter medium 13. The fluid passing through the filter medium 13 also passes smoothly without resistance. As the fluid smoothly passes through the filter medium 13 as described above, the function of the filter medium 13 is also improved.

On the other hand, the material of the fixture 100 is satisfied if the material is higher in strength than the material of the filter medium (13). Specifically, a metal material, that is, aluminum or an aluminum alloy, iron plate, etc. can be produced by press working, it can be produced by injection molding not a metal material but also a synthetic resin material. In addition to this, not only can be manufactured with rubber, wood, etc., but also as a material such as the filter medium 13, it can be manufactured by making a thicker than the thickness of the filter medium (13).
