5 to 9, a cartridge filter bag 100 according to an embodiment of the present invention is disposed inside a dust collector housing (not shown) to collect dust or the like, which is introduced into a dust collector housing, And discharging the cleaned air.

Here, the cartridge filter bag 100 includes an inner cage 200, an outer cage 300, and a filter cloth 400.

Particularly, the cartridge filter bag 100 according to the present invention is manufactured so that the modular filter cloth 400 is assembled so as to be located on the outer side of the inner cage 200 and the outer cage 300 is assembled to the outer side of the filter cloth 400 So that the assemblability is improved.

At this time, the centers of the assembled inner cage 200, the filter cloth 400, and the outer cage 300 are constrained to coincide with each other. This is because the circumferential surface trajectory of the inner cage 200 and the circumferential surface of the filter cloth 400 are maintained at a constant distance and the circumferential surface of the filter cloth 400 and the circumferential surface trajectory of the outer cage 300 maintain the set distance So as to reduce the resistance due to the flow of the outside air.

More specifically, the inner cage 200 includes an inner upper cap 220, an inner elastic rod 210, and an inner lower cap 230.

The inner upper cap 220 may have various shapes such as a plate shape and may be formed of various materials. In addition, the inner upper cap 220 forms an inner opening 222 so that the filter cloth 400 can be inserted therein. At this time, the inner opening 222 is formed in a concave-convex shape so as to insert the filter cloth 400 having a corrugated surface. This is because the inner opening 222 maintains the shape of the filter cloth 400.

The inner elastic rods 210 extend downwardly from the inner upper cap 220 and are spaced a predetermined distance along a circular trajectory in a plane.

At this time, the inner elastic bar 210 extends from each of the valleys of the inner opening 222 having the ridges of the inner upper cap 220.

In addition, each of the inner elastic rods 210 may be connected to the inner upper cap 220 in various ways such as by bolting or welding.

The inner lower cap 230 connects and fixes the lower side of each of the inner elastic rods 210. At this time, the inner lower cap 230 is connected and fixed to the inner elastic rods 210 by various methods such as bolting and welding. Particularly, when the filter cloth 400 is inserted into the inner opening 222 of the inner upper cap 220, the inner lower cap 230 is sized to pass through or pass through the filter cloth 400. Of course, the inner bottom cap 230 can be deformed into various shapes and various materials.

Meanwhile, the outer cage 300 includes an outer upper cap 320, an outer elastic rod 310, and an outer lower cap 330.

The outer upper cap 320 is formed in a plate shape or the like positioned on the upper side of the inner upper cap 220. Of course, the outer upper cap 320 may be made of various materials. At this time, since the outer upper cap 320 has to connect or bind the filter cloth 400, the filter cloth 400 has the flange 430. This is to prevent the filter cloth 400 from generating noise due to shaking inside the outer cage 300.

In particular, the outer top cap 320 may be pierced through the outer opening 322 to permit the entry and exit of the cleaned outside air.

The outer elastic rods 310 extend downward from the outer upper cap 320 and are spaced a predetermined distance along a circular trajectory in a plane. At this time, the diameter of the circular trace formed by the outer elastic rods 310 becomes larger than the diameter of the circular locus formed by the inner elastic rods 210.

Each of the outer elastic rods 310 is assembled so as to be disposed on a mountain portion of the circumferential surface concave and convex portions of the filter fabric 400 and the inner elastic rods 210 are assembled do.

In addition, each of the outer elastic rods 310 may be connected to the outer upper cap 320 in various ways such as bolting or welding.

The outer lower cap 330 connects and fixes the lower side of each of the outer elastic rods 310. At this time, the outer lower cap 330 connects and fixes the outer elastic rods 310 by various methods such as bolting and welding. Particularly, when the filter cloth 400 inserts the outer elastic rod 310, the outer lower cap 330 is sized and passed through the filter cloth 400. Of course, the outer lower cap 330 can be deformed into various shapes and various materials.

Meanwhile, the filter cloth 400 directly filters and collects the dust contained in the outside air introduced into the dust collector housing.

In particular, the filter cloth 400 may be made of any one of PE, PP, GLASS WOOL, Nomex and Teflon, or a combination thereof.

In addition, the filter cloth 400 forms irregularities along the circumferential direction on the peripheral surface to increase the contact area with the outside air for collecting the dust. That is, the filter cloth 400 forms the crest 410 and the valley 420 along the circumferential trajectory.

At this time, the inner elastic rods 210 are assembled to the filter cloth 400 so as to be arranged in one-to-one relation with the valleys 420, and the outer elastic rods 310 are assembled to the filter cloth 400 so as to be arranged one-

The filter cloth 400 is inserted into the inner opening 222 of the inner upper cap 220 and is positioned inside the outer elastic cage 210 and inside the outer cage 300.

For the sake of convenience, the filter cloth 400 is inserted and assembled from the upper side to the lower side of the inner cage 200, and the outer cage 300 is assembled to cover the filter cloth 400 from the upper side to the lower side of the filter cloth 400 do. Accordingly, the inner lower cap 230 is positioned on the upper side of the outer lower cap 330.

On the other hand, the filter cloth 400 has a flange 430 on one side (upper side) so as to maintain the shape of the crest portion 410 and the valley portion 420. Particularly, the flange 430 is fixed to the upper end of the filter cloth 400 by adhesion, bolting, or the like, and forms an inlet 432 along the trajectory of the hill part 410 and the valley part 420.

Particularly, the inner opening 222 of the inner upper cap 220 and the inlet 432 of the flange 430 are formed with the same concavo-convex locus so that the crests 410 and the valleys 420 of the filter cloth 400 can be inserted .

Thus, the outer elastic rod 310 is inserted one-to-one into the mountain portion of the inlet 432. Accordingly, the filter cloth 400 is held in a primary shape by the flange 430, and the inner elastic bar 210 and the outer elastic bar 310 maintain the secondary shape.

In addition, the inner upper cap 220, the flange 430, and the outer upper cap 320 are stacked in order, and can be coupled to one another by bolting or the like.

Further, the filter cloth 400 may be formed so that the lower side thereof is clogged or opened.

Meanwhile, the outer upper cap 320 may be integrally or separably provided with a ventilation-inducing venturi 500 for guiding the flow of air. That is, the escape-inducing venturi 500 may be provided at the outer opening 322 of the outer upper cap 320.

In particular, the ventilation-inducing venturi 500 serves to guide the purified external air to the outside of the cartridge filter bag 100, and the expanded portion 510 can be formed on the lower side and the upper side.

The expansion portion 510 reduces the resistance of the air introduced into the exhaust-gas induction venturi 500 and spreads the forced air to reduce the discharge speed.

Conversely, when the outside air flows into the cartridge filter bag 100 through the escape-inducing venturi 500, the expanded portion 510 diffuses and induces the air to be blown so that air is blown over the entire inner surface of the filter cloth 400 It is important to understand that

In addition, the inner cage 200 may include an outermost mesh network 240 that surrounds the entire bag filter 100. The outermost mesh network 240 serves to further improve the air cleaning force in addition to the filter fabric 400. At this time, the outermost mesh net 240 is fixed to the inner upper cap 220 and the inner lower cap 230, thereby covering the entire circumferential surface of the inner cage 200 or the entire circumferential surface of the cartridge bag filter 100.

In particular, the inner lower cap 230 may extend at least one of the support ribs 232 to support the lower inner side of the outermost mesh net 240 and maintain the clearance with the filter cloth 400. Of course, the support rib 232 can be deformed into various shapes.

10 is a longitudinal sectional view of a cartridge filter bag according to another embodiment of the present invention.

Referring to FIG. 10, a cartridge filter bag 100 according to another embodiment of the present invention includes an inner cage 200, an outer cage 300, and a filter cloth 400.

At this time, the inner cage 200, the outer cage 300, and the filter cloth 400 are replaced with those described above.

The outer elastic rods 310 and the inner elastic rods 210 disposed on both sides with respect to the filter cloth 400 are provided with electromagnets 600 which alternate repulsive force and attractive force, ) Can be induced.

That is, the outer elastic bar 310 and the inner elastic bar 210 are provided with the electromagnets 600 to correspond to each other. As a result of the repetitive power supply of the electromagnet 600, vibrations are generated by the adjacent or opposing outer elastic rods 310 and the inner elastic rods 210, so that the filtering cloth 400 is shaken and the dust removing efficiency is improved.

Of course, the electromagnet 600 is coupled to the outer elastic bar 310 and the inner elastic bar 210 in various ways, and is not limited to the number.

The reference numerals not described are replaced with those described above.
