Description

Filter support structure for dust collector

The present invention relates to a filter support structure for a dust collector, and more particularly, the filter is opened by compressed air supplied when the compressed air is periodically supplied in a reverse direction so that a shock wave is generated to remove dust, fine particles, etc. caught on the filter. The present invention relates to a filter support structure for a dust collector that prevents crushing and the like and maintains the shape of the filter and allows the filter to return to its original shape.

The dust collector is an apparatus for purifying air by removing dust, fine particles, and the like contained in the air, and generally includes a filter.

In recent years, the cross section has a star shape in a zigzag form in order to improve the dust collection efficiency by widening the area where the filter is in contact with air.

In addition, as a material of the filter, synthetic resins such as polyester, polypropylene for low temperature, meta-aramide for high temperature, poly phenylene sulfide (pps), and the like are used.

The filter sucks air from the outside of the filter to the inside to remove dust and fine particles contained in the air, and the dust and fine particles accumulate on the outer circumferential surface of the filter, which reduces the dust collection efficiency. Polishing is performed to remove particulates and the like.

Polishing operation intermittently supplies compressed air to the inside of the filter to generate shock waves in the filter, thereby removing dust, fine particles, and the like.

At this time, the filter has a zigzag shape, so that the cross-sectional shape becomes a star shape, so when the compressed air is intermittently supplied into the filter, the filter is swollen, and the cross-sectional shape of the filter does not maintain the star shape. do. When the filter is opened in this way, it is difficult for the filter made of a synthetic resin material such as polyester, polypropylene, meta-aramide, and poly phenylene sulfide (pps) to be returned to its original shape. In particular, when the filter has a long length to increase the dust collecting capacity, the phenomenon that the filter is opened during the polishing operation becomes prominent.

In order to prevent this phenomenon, conventionally, the outer circumferential surface of the filter was manually tied to a string with a predetermined interval in the longitudinal direction of the filter.

However, such a string is a problem that does not become a fundamental measure because it is released or broken in accordance with a long time use.

In order to improve the above problems, Korean Patent Registration No. 10-1547671 (name of the invention: a filter for dust collector) has been disclosed and filed by the present applicant.

The filter for dust collector is provided with a filter shape holder for restraining the filter from spreading outward when compressed air is introduced through the through-hole when removing foreign matters accumulated on the outer circumferential surface of the filter, to maintain the shape of the filter. The part consists of a longitudinal member and a circular ring or a spiral ring.

The filter for dust collectors having the above-described structure may cause the filter to be opened or crushed by the compressed air supplied when the compressed air is periodically supplied in the reverse direction so that a shock wave is generated in order to remove dust, fine particles, etc. caught in the filter. It is effective to extend the life of the filter by preventing it to maintain the shape of the filter.

However, the filter shape holder is fixed to the outside of the filter to restrain the filter from spreading outward when compressed air is introduced through the through hole when foreign matters accumulated on the outer circumferential surface of the filter are removed. Since it is formed into a corrugated star alternately inward and outward, when the compressed air is introduced, the star protruding portion of the filter collides with the longitudinal member, the circular ring or the spiral ring, and wears out, and during frequent cleaning There is a problem that the filter is torn in case of damage or severe according to the wear of the site.

In the case of the soft filter, a mark is formed at the collision part between the vertical member, which is the shape of the filter, and the circular ring or the spiral ring, and the deformation of the filter is caused by repeated collisions, which makes it difficult to maintain the shape of the filter. There is a problem.

In addition, the filter has a zigzag cross-sectional shape to form a star shape, but when the compressed air is intermittently supplied, the filter swells. When the filter swells, the filter shape retaining portion is formed of a vertical member and a circular ring or a spiral ring. The swelling of the filter is suppressed by the elasticity of the filter itself, but after polishing, there is a problem in that the axial symmetry is not achieved because a narrow or wide area of the protruding portion of the filter is formed. As such, when the cross-sectional shape of the filter is not symmetrical, dust is not evenly filtered at the outer periphery of the filter during dust collection, and the space between the protruding portions of the filter is concentrated at a wide area, preventing efficient filtration. There is a problem.

In order to prevent this phenomenon, a star-shaped ring, which is the same as the cross-sectional shape of the filter, may be installed in contact with the outer circumference of the filter, but this is also a problem of the filter shape maintaining part including the vertical member and the circular ring or the spiral ring. Similarly, when polishing, marks remain on the filter by a star-shaped ring, or when the filter is recessed due to repetitive collision between the star-shaped ring and the filter, or in severe cases, the filter may be damaged. .

An object of the present invention is to prevent the filter from being opened or crushed by the compressed air supplied when the compressed air is periodically supplied in the reverse direction so that a shock wave is generated to remove dust, fine particles, etc. caught on the filter. To provide a filter support structure for the dust collector to maintain the shape and at the same time prevent the filter from being deformed or damaged.

The outer protrusion fixing plate 63 is formed in a plate shape and is provided in contact with both sides of the outer protrusion 41, and coupling holes 63a are formed on both sides to couple them to each other. The outer protrusion fixing plate 63 is formed long from the center bottom to the top and is formed with a spring fixing plate insertion groove 63b into which the spring fixing plate 62 is inserted.

The fastening portions 64 are respectively coupled to the coupling holes 63a of the outer protrusion fixing plates 63, respectively, and serve to fasten the pair of outer protrusion fixing plates 63 to each other.

At this time, the outer protrusion 41 corresponds to the coupling hole (63a) is formed with an insertion hole (41a) is inserted into the fastening portion (64).

By fastening to the coupling hole (63a) is fixed to the outer projection fixing plate 63 for fixing to each other. When the outer protrusion fixing plate 63 is coupled to each other by the fastening unit 64 as described above, the outer protrusion 41 is positioned between the pair of fixing plate 63 for fixing the outer protrusion, and a pair of the The fixing plate 63 for fixing the outer protrusions is firmly fixed to the outer protrusions 41. When the pair of outer protrusion fixing plate 63 is fixed to the outer protrusion 41, the spring fixing plate 62 is prevented from being separated upward by the upper portion of the outer protrusion fixing plate 63. The spring fixing plate 62 is also to be fixed.

The spring fixing plate 62 is prevented from being separated from the spring fixing plate 62 by the upper portion of the fixing plate 63 for fixing the outer protrusions, so that the spring fixing plate 62 is fixed, but the spring fixing plate ( Since the outer protrusion 41 is inserted into the outer protrusion insertion groove 62b of the 62 perpendicular to the outer protrusion 41, the spring fixing plate 62 may be left-right flowed in the longitudinal direction of the filter 40. . As such, when the spring fixing plate 62 causes the left and right flow in the filter 40 lengthwise direction, the spring 50 fixed to the spring fixing groove 62a of the spring fixing plate 62 also generates a flow. It is preferable to prevent the left and right flow of the spring fixing plate 62.

In order to prevent the left and right flow of the filter 40 in the longitudinal direction of the spring fixing plate 62, the fixing plate seating groove 62c is provided at the center upper end of the spring fixing plate 62.

The fixing plate seating groove 62c is formed at the top of the center of the spring fixing plate 62, and the pair of fixing plates 63 for fixing the outer protrusions to the spring fixing plate 62 inserted into the spring fixing plate insertion groove 63b. The upper part is seated so as to prevent the left and right flow of the filter 40 in the longitudinal direction of the spring fixing plate 62.

When the fixing plate seating groove 62c is formed at the upper end of the spring fixing plate 62, when the fixing plate 63 for fixing the outer protrusion to the spring fixing plate 62 is coupled, the fixing of the outer protrusion to the spring fixing plate 62 is performed. The upper portion of the fixing plate 63 is seated so that the left and right flow of the filter 40 in the spring fixing plate 62 is prevented by the upper portion of the fixing plate 63 for fixing the outer protrusion.

In addition, in the present invention, the inner and outer protrusions 41 protruding in the shape of stars after polishing the filter 40 to form a constant axisymmetric mutually, as shown in Figure 2, as shown in Figure 2, Preferably, one outer projection 41 is inserted between each coil 51 and the coil 51 adjacent thereto.

When one outer protrusion 41 is inserted between each coil 51 of the spring 50 and the coil 51 adjacent thereto, one outer protrusion 41 and the outer protrusion adjacent thereto are provided. The interval between the 41 is constant, and the same elastic force is applied, so that the filter 40 is axisymmetric as a whole.

When each of the one outer protrusion 41 is inserted between the coil 51 of the spring 50 and the coil 51 adjacent thereto, the spring 50 is the filter ( Compared to the outer circumferential edge of 40, the filter 40 can achieve axial symmetry.

As such, when the inner and outer protrusions 41 protruding in a star shape maintain a constant interval, the gap between the protrusions is prevented from being concentrated and filtered so that the filter is evenly filtered throughout the filter. Filtration is possible and the dust collection efficiency can be improved.

In addition, the fastening part 64 may be a bolt and a nut, but since the bolt and nut take a long time to fasten with each other, the fastening time may be shortened and the insertion hole 41a of the outer protrusion 41 may be removed. It is preferable to be a rivet in consideration of the sealing.

In the filter 40, the filter 40 includes a plurality of inner and outer protrusions 41 each protruding inward and outward so as to form a corrugated star alternately inward and outward in a circumferential direction. It is generally formed in a cylindrical shape, provided with an adhesive portion 41b which is formed to be formed to be folded, and bonds or stitches the outer protrusions 41 located at the side end portions to each other in the longitudinal direction (see FIGS. 7 and 8).

At this time, it is preferable that the fixing plate 63 for fixing the outer protrusion of the spring fixture 60 is fixed to the outer protrusion 41 of the filter 40 provided with the bonding part 41b.

As such, when the fixing plate 63 for fixing the outer protrusion of the spring fixture 60 is fixed to the outer protrusion 41 of the filter 40 provided with the bonding part 41b, the adhesive part 41b for sewing with adhesive or thread is fixed. It also serves to reinforce the adhesive force.

In addition, the spacing distance of the spring 50 is preferably smaller toward the lower support 10 direction.

The reason why the spacing distance of the spring 50 becomes smaller as it goes toward the lower support portion 10 is when compressed air is introduced through the through hole 21 when removing foreign matters accumulated on the outer circumferential surface of the filter 40. The closer to the lower support 10, the greater the pressure caused by the compressed air, so as to efficiently maintain the shape of the filter 40.

In addition, it is preferable that a metal mesh (not shown) contacting the inner circumferential surface and the outer circumferential surface of the filter 40 and formed in the shape of a corrugated star alternately inward and outward along the circumferential direction are the same as the filter 40. Do.

The metal mesh is in contact with the filter 40 on the inner circumferential surface and the outer circumferential surface of the filter 40, and when the filter 40 is filtered and the foreign matter accumulated on the outer circumferential surface of the filter 40 is removed through the through-hole 21. It serves to give strength to maintain the shape of the filter 40 when the compressed air is introduced. Like the filter 40, the metal mesh is also formed in a corrugated star shape alternately inward and outward along the circumferential direction.
