Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fluid cleaner 11 with a filtration element for gases or fluids.

Conventionally, as a filtration element in this type of fluid purifier, a filtration element made of P material such as nonwoven fabric in P paper has been used. In this filtration element, the fibers exfoliated in the cuttings of the material or the manufacturing process of the filtration element, tfF, are fluid cleaning.

It is conceivable that foreign matter adhering to the P material during the assembly process of the vessel may enter the downstream side of the fluid purifier without being filtered.

In such a case, if the engine is provided with a Rieke valve or the like on the downstream side of the fluid purifier, the function of the engine may be impaired due to the attachment of foreign matter.

The present invention has been made in view of the above points, and is a secondary filter in which a synthetic resin or metal mesh is insert-molded in a synthetic resin groove on the downstream side of a filtration element installed to allow fluid to flow in the axial direction. By providing a filter, the purpose is to further improve filtration performance and provide a highly reliable fluid purifier.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention shown in the drawings will be described.

First, the transit element used in the fluid purifier of the present invention will be described. The P-column shape of the filtration element is a trapezoid with a short width at one end and a long width at the other end, as shown in FIG. When this trapezoidal lid P material 1 is folded along folding lines ``B-B', 0-C', . . . K- with a constant folding width, R material 1 A P material 2 having a corrugated section in which a plurality of continuous top rows and bottom rows are formed between both ends of the P material 2 is obtained.This P material 2 is folded as shown in FIG. Since the folded area is small, that is, the width dimension is short, it is curved in a ring shape (including an ellipse) with Moum', B-B' on the inner circumferential side, and both ends of it are shaped like a tree I11.
3 K is concentric circles! 1! A filter element 4 is obtained. In addition, the material of the P material 1 constituting the filtration element 4 is as follows:
It is made of stretchable non-woven fabric.

As the fluid purifier of the present invention, a secondary filter 5 in the form of a disc, for example, is installed downstream of the filtration element 4 configured as described above.
from the button with resin adhesive, etc., and attach the composite filtration element 6.
is obtained. The secondary element 5 is formed by insert molding a nylon mesh 8 into a lip 7 made of, for example, nylon, as shown in FIG.

Furthermore, although the concentric element 4 described above is constructed using the trapezoidal F material 1, the filtration element may be constructed using a fan-shaped R material. In this case, since there is no difference in the circumferential length of the e-element 40, there is no need to use a stretchable material as the material for the P material 1;
Any material such as felt can be used.

Next, a case will be described in which the support structure for the filter element 6 having the above configuration shown in FIG. 4 is applied to an air cleaner for an internal combustion engine. In the air purifier for an internal combustion engine shown in FIG. 6, a cylindrical portion 11a is fitted into the inner circumference of the one-pass element/toro shown in FIG. 4, and is integrally formed with the cylinder s11a. A resin support frame 11 is used which is equipped with a circular porous support part 111) that supports the bottom of the element 6, and the inner peripheral part of the filter element 6 is attached to the cylindrical part 11a of the frames 1 and 10 with adhesive. It is glued with glue. On the other hand, the outer periphery of the overpass element 6 is bonded to the supporting portion 11b of the frame 11 with adhesive B. This receiver frame 11 is supported by a support frame 10 made of resin and fixed to the case 9. Also,
The receiver has a gasket 12 glued to the outer part of the frame 11.
The sket 12 is sandwiched between the case 9 and the cap 13 to maintain airtightness. Furthermore, case 9
and the cap 13 are connected by an I-rut 14 and a nut 15, and are kept airtight by a gasket 16. Further, the secondary filter 5 may of course be integrally molded with the resin receiving frame 11 having the porous support portion 111), and this embodiment is shown in FIG.

The operation in the above configuration will be explained. As shown in FIGS. 6 and 9, contaminated air flowing in from the air inlet pipe 1T as indicated by the arrow is collected by the filter element 4 and then by the secondary filter 5. At that time, scraps of the f material coming out of the filter element 4, peeled fibers, etc.
Alternatively, foreign matter that has adhered to P# during the manufacturing process of the filtration element or the assembly process of the air purifier is designed to be collected by the secondary filter 5.
The beneficial performance is improved, resulting in a highly reliable fluid purifier.
