接続され機械的な強度を向上させることができる。Here, as shown in FIG. 2, the first perforated plate 21 at the forefront of the ventilation path A is formed so that the long holes 21a communicate from the upper part to the lower part of the first perforated plate 21. Thus, unlike the second perforated plate 22 on the rear side, for example, the adhered dust below the long holes 22a located above the long holes 22a in the two stages does not flow and slightly remains. That is, in a filter in which a plurality of perforated plates are juxtaposed, most of the large dust is captured by the non-porous portion 21b of the first foremost perforated plate 21 and communicates from the upper portion to the lower portion of the first perforated plate 21. Since it is flown over the non-hole portion 21b along the long hole 21a, the amount of the adhered residue below the long hole 22a of the rear porous plate 22 can be made small, and, for example, like the rear porous plate 22, Mechanical strength can be easily secured as the two-stage long holes 22a, 22a. In this case, as shown in FIG. 4, the rearmost first perforated plate 21 is closed such that the lower portion of the long hole 21 a is closed and the lower edge of the first perforated plate 21 is opened at the edge of the long hole 21 a. By bending to the side, the dust flowing down the long hole 21a can flow down through the opening 21d at the lower edge of the perforated plate of the long hole 21a.
No dust remains on the lower part, and the connecting piece 21c connecting the lower part of the non-hole part 21b is integrally formed and bent rearward, so that the lower part is connected by the connecting piece 21c and Strength can be improved.

The width of the non-hole portion 22b between the long holes 22a on the downstream side of the perforated plate 22 is smaller than the width of the non-hole portion 21b between the long holes 21a on the upstream side of the first perforated plate 21 on the upstream side. It is narrowed to improve the cleaning property of the non-hole portion 22b on the downstream side. That is, the non-porous portion 2 of the perforated plate 22 on the downstream side
2b is washed with water sprayed through the long holes 21a on the upstream side, but by reducing the width of the non-holes 22b between the long holes 22a on the downstream perforated plate 22, the cleaning efficiency is increased and In addition, the contact area with dust such as oil and dust can be reduced, and cleaning can be performed as cleanly as the non-porous portion 21b of the first porous plate 21 on the upstream side. Further, the filter 2 according to the present invention has a number of perforated plates other than those described above, for example, 3
A plurality of filters, such as a filter, wherein the filter has a first perforated plate 21 at the forefront of the ventilation path A in which the long holes 21a communicate from the upper part to the lower part as described above; By forming the long hole 22a on the rear side of the second 21 by the two second perforated plates 22 formed in the upper and lower two stages, a multi-layered structure with a minimum number of perforated plates at low cost. The oil collecting performance can be maintained effectively.

Since the oil, dust, and the like adhering to 1 can flow along the long hole 21a communicating from the upper part to the lower part, the amount of the residual residue on the lower part of the long hole 22a of the rear porous plate 22 can be reduced. Thus, the mechanical strength of the perforated plate 22 can be easily secured. In addition, oil, dust and the like adhering to the first perforated plate 21 are passed through the opening 21d formed by closing the lower end of the long hole edge of the long hole 21a communicating from the upper part to the lower part and bending backward. Since it can flow down, it can flow down easily, and the mechanical strength of the first porous plate 21 can be easily secured. In addition, the filter 2 includes a first perforated plate 21 at the forefront of a ventilation path formed such that a long hole 21 a communicates from an upper portion to a lower portion thereof, and a first perforated plate 21.
Since the long hole 22a on the rear side is constituted by two second perforated plates 22 formed in two steps of an upper part and a lower part,
By using a multi-structure filter with a minimum number of perforated plates, oil collection performance can be effectively maintained at low cost.
The second perforated plate 22 on the rear side of the perforated plate 21 and the first perforated plate 21
The distance between the two sheets can be kept constant by preventing warping of the sheets, and the air purification performance can be stably maintained.
