Description

[0001] The present invention relates to a filter cartridge for a dust collector,

The present invention relates to a filter cartridge installed inside a dust collector through a through hole formed in a shield plate of a dust collector, and relates to a filter cartridge for a dust collector in which a packing member closely attached to a through hole is coupled to a filter body.

Generally, the filter cartridge is installed in a dust collector to remove dust contained in air introduced into the dust collector, thereby discharging only clean air from which dust has been removed.

As shown in FIGS. 1 and 2, the conventional filter cartridge 1 has a circular filter cloth 11 folded in a predetermined width so as to form a corrugation in a longitudinal direction, And a top cap 13 coupled to an upper end of the filter cloth 11. The filter main body 10 is coupled to the upper cap 13 to block the dust collector A, And a holder 20 press-fitted into the through-hole C formed in the plate B.

A ring-shaped packing member 30 for increasing the coupling force between the holder 20 and the through hole C is coupled to the through hole C.

The packing member 30 is composed of a ring-shaped body 31 formed of a processed fiber material and a metal spring 32 inserted in a ring shape at the upper and lower parts of the body 31. The metal spring 32 is positioned on the upper side and the lower side of the through hole C and is brought into close contact with the through hole C by elastic force so that the body 31 of the packing member 30 is not separated from the through hole C Fix it.

The outer peripheral wall of the holder 20 is provided with an annular recessed portion 21a extending along the circumferential direction and a stopper portion 21 formed of an annular protruded portion 21b projecting outwardly so as not to be easily separated from the packing member 30 Is formed.

Therefore, after the ring-shaped packing member 30 is fitted to the through hole C formed in the shield plate B of the dust collector A, the stopper portion 21 of the holder 20 is fitted to the packing member 30 When the filter cartridge 1 is inserted into the packing member 30 to be engaged in the press-fitted state, the installation of the filter cartridge 1 is completed.

However, since the conventional filter cartridge 1 has a structure in which the packing member 30 is installed in advance in the passage hole C, workability is greatly reduced. If the filter cartridge 1 is inserted into the through hole C with the packing member 30 already mounted on the holder 20 of the cartridge, The spring 32 interferes with the through hole C, so that the filter cartridge 1 can not normally be installed in the through hole C.

The conventional filter cartridge 1 has a structure in which the holder 20 and the packing member 30 are formed separately and the metal spring 32 of the packing member 30 exerts an elastic force F toward the through- The adhesive force between the holder 20 and the packing member 30 is reduced and a gap is liable to be generated and the dust sometimes flows out to the outside.

In addition, since a gap is formed in the conventional filter cartridge 1 because the upper cap 13 and the holder 20 are attached through the spot weld S, the dust inside the dust collector A passes through this gap There is a problem that it flows into the inside of the filter body 10 without passing through the filter cloth 11.

The features and advantages of the present invention will become more apparent from the following detailed description of preferred embodiments with reference to the accompanying drawings. Prior to this, terms and words used in the present specification and claims are to be interpreted in accordance with the technical idea of the present invention based on the principle that the inventor can properly define the concept of the term in order to explain his invention in the best way. It must be interpreted in terms of meaning and concept.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings. The same reference numerals are used for the same components, and only the different portions are described for the sake of clarity.

3 and 4, the filter cartridge for a dust collector according to the present invention includes a filter body 100, a holder 200 attached to an upper end of the filter body 100, And basically includes a combined packing member 300.

The filter body 100 includes a filter bag 110 having a circular shape that is folded in a predetermined width so as to form a valley in the longitudinal direction and is crimped, a lower end cap 120 coupled to close the lower end of the filter bag 110, And a top cap 130 coupled to an upper end of the filter fabric 110.

The upper cap 130 of the present invention may be formed into a circular frame shape having a terminator cross section so as to cover the upper outer edge of the filter fabric 110. In this case, the lower part of the holder 200 has a horizontal surface 201 integrally attached to the upper cap 130 through a spot weld S, and a lower surface bent downward from the horizontal surface 201 to closely contact the inner circumferential surface of the filter body 100 And a vertical surface 202 joined thereto.

The upper portion of the filter cloth 110 is filled with an adhesive 140. The adhesive 140 prevents the gap between the horizontal surface 201 and the upper cap 130 generated due to the adhesion between the horizontal surface 201 of the holder 200 and the upper cap 130 through the spot welding S Dust from the dust collector is prevented from flowing into the interior of the filter body 100 through the gap without passing through the filter fabric 110.

As shown in FIGS. 5 and 6, the upper cap 130a may be formed into a circular frame shape having a diagonal section so as to cover the upper end of the filter fabric 110. FIG. In this case, a plurality of through holes 131 are formed on the upper surface of the upper cap 130a. The upper surface of the upper cap 130 and the lower portion of the holder 200 are integrally attached by spot welding S between the through hole 131 and the through hole 131. In addition, the through hole 131 is filled with an adhesive 140. The adhesive 140 prevents the dust inside the dust collector from penetrating through the gap between the horizontal surface 201 of the holder 200 and the upper cap 130, .

On the other hand, on the outer circumferential surface of the holder 200, a protrusion 210 is formed along the circumferential direction. A concave portion 220 is formed on the outer circumferential surface of the holder 200 along the circumferential direction. The concave portion 220 is formed at a predetermined distance below the protrusion 210.

The packing member 300 tightly coupled to the outer periphery of the holder 200 includes a body 310 surrounding the outer circumference of the holder 200, an upper contact portion 320 formed on the upper portion of the body 310, And a lower tight contact portion 330 formed at a lower portion of the holder 200. The lower fastening portion 330 is coupled to the holder 200 so as to surround the outer circumferential surface thereof.

The upper contact part 320 is formed at the upper end of the body part 310 so as to protrude in the radial direction of the through hole C formed in the shield plate B of the dust collector and interferes with the upper end of the through hole C, And is brought into close contact with the holder 200 by an elastic force.

The lower adhesion part 330 is formed at the lower end of the body part 310 so as to protrude toward the concave part 220 and is closely attached to the concave part 220 of the holder 200 by its own elastic force.

Accordingly, the upper tight contact portion 320 protrudes from the body portion 310, but the lower tight contact portion 330 does not protrude from the body portion 310.

The body portion 310 of the packing member 300 is provided with a central contact portion 350 that surrounds the protrusion 210. The central contact part 350 protrudes toward the radially outer side of the through hole C by the thickness of the packing member 300. When the filter cartridge of the present invention is installed in the through hole C formed in the shielding plate B of the dust collector, the central adhered portion 350 is contracted and passes through the through hole C, C to prevent the filter cartridge from being displaced upward of the through-hole C, as shown in Fig. The diameter of the protrusion 210 should not exceed the diameter of the through hole C so that the protrusion 210 may pass through the through hole C and the diameter of the center close contact 350 may be larger than the diameter of the through hole C C so as to be able to interfere with the lower end of the through hole (C).

As shown in FIG. 7, the packing member 300 may be manufactured by sewing a nonwoven fabric. The upper and lower contact parts 320 and 330 may include elastic bands D inserted into the upper end of the body part 310 and elastic bands D inserted into the lower ends of the body part 310, ). As the elastic band D, a rubber band or a metal spring is suitable.

As shown in FIG. 8, the packing member 300a may be manufactured through injection molding. In this case, the body 310 is preferably made of a rubber material having self-elasticity. As the rubber material, EPDM heat resistant rubber, silicone rubber, or the like is suitable in consideration of the high temperature environment inside the dust collector.

A step portion 312 surrounding the protrusion 210 of the holder 200 protrudes from the outer circumferential surface of the body portion 310 when the packing member 300a is manufactured through injection molding, The protrusion 340 that is in close contact with the inner circumferential surface of the through hole C of the shield plate B formed in the shield plate B of the first embodiment can be integrally formed. The protrusion 340 is formed in a circumferential direction along the outer circumferential surface of the body portion 310. The protrusions 340 may be formed at a plurality of intervals. The protrusion 340 provides strong adhesion between the through hole C and the body 310 of the packing 300 so that the protrusion 340 passes between the through hole C and the body 310 of the packing 300 Thereby more reliably preventing the dust inside the dust collector from flowing out.

The filter cartridge for a dust collector according to the present invention is constructed in such a manner that the filter body 100, the holder 200 and the packing member 300 are integrally coupled to each other and the through hole C formed in the shield plate B of the dust collector. Is installed as follows.

9, when a worker inserts the lower portion of the filter body 100 into the through hole C, the lower contact portion 330 of the packing member 300 contacts the recess 220 of the holder 200 The central contact portion 350 of the packing member 300 surrounding the protrusion 210 of the holder 200 does not protrude from the body portion 310 because the protrusion protrudes toward the body portion 310 because the protrusion protrudes toward the body portion 310. [ The filter main body 100 is inserted smoothly without any interference with the through hole C until it interferes with the through hole C. [

The operator strongly presses the holder 200 downward when the insertion of the body part 310 of the packing member 300 surrounding the protrusion 210 of the holder 200 interferes with the through hole C and stops the insertion.

The central contact portion 350 surrounding the protrusion 210 is pressed against the inner circumferential surface of the through hole C so that the protrusion 210 passes through the through hole C when the holder 200 is pressed. When the protruding portion 210 passes through the through hole C, the contracted central tight fitting portion 350 expands originally and interferes with the through hole C again. As a result, the filter body 100 is allowed to pass through the through hole C is prevented.

4, when the central contact part 350 passes through the through hole C, the body part 310 of the packing member 300 closely contacts the inner peripheral surface of the through hole C, The protruded upper tight contact portion 320 closely contacts the upper portion of the through hole C and stably maintains the close contact state due to the self weight of the filter body 100 so that the dust inside the dust collector passes through the packing member 300 And does not flow out to the outside of the dust collector through the space (C).

The present invention is advantageous in that the packing member 300 is coupled to the holder 200 so that the operator can carry out the pressing operation of the packing member 300 very easily in the through hole C Since the elastic force of the packing member 300 acts on the side of the holder 200 as well as the adhesion between the holder 200 and the packing member 300 is very excellent, .

The adhesive 140 is filled in the upper portion of the filter cloth 110 so that the dust inside the filter can penetrate the filter body 100 without passing through the filter cloth 110 through the gap between the holder 200 and the upper cap 130. [ Is prevented.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be takeners of ordinary skill in the art, And such variations are within the scope of the present invention.
