[0001] APPARATUS FOR DEDUSTING A DUST COLLECTOR FILTER CLOTH [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a dust bag filtering apparatus, and more particularly, to a dust bag filtering apparatus capable of removing dust remaining inside and outside of the dust bag filtering cloth.

As the severity of air pollution in recent years has increased, the emission allowance standards for air pollutants have been strengthened, requiring replacement and supplementation of air pollution prevention facilities installed in each industry.

The filtration and dust collecting apparatus, which is one of the most installed high efficiency dust collecting apparatuses, is in demand due to its high dust collecting efficiency. However, since the dust collecting efficiency for the fine particles below 1 μm is low and the high pressure loss caused by the filter cloth Due to the limitation of the filtration speed, there is a disadvantage that installation scale is large, and it takes a lot of economic costs such as installation and maintenance, management cost, and the like.

Also, in the past, a method of tearing the dust filter bag one by one by hand or washing with water was used.

However, these methods are time consuming, wastewater treatment and dust are scattered.

Also, there is a problem that the filtration performance is poor even when reused.

A prior art related to the present invention is Korean Patent Laid-Open No. 10-2011-0106967 (September 30, 2011).

SUMMARY OF THE INVENTION An object of the present invention is to provide a dust filter bleeding apparatus that can remove dust remaining inside and outside of a dust collector filter cloth.

Another object of the present invention is to provide a dust filter bleeding apparatus capable of removing dust remaining in a filter cloth without removing the filter cloth from the dust collector, thereby improving the efficiency of use.

FIG. 2 is an exploded cross-sectional view showing the dust filter bleeding apparatus of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a dust bag filtering apparatus according to the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a view showing a dust bag filtering apparatus according to the present invention, and FIG. 2 is an exploded sectional view showing a dust bag filtering apparatus according to the present invention.

A description will be given of the structure of the dust filter bleeding apparatus of the present invention and the process of dust exhaustion of the dust remaining in the filter cloth will be described with reference to the structure thereof.

1 and 2, a dust bag filtering apparatus according to the present invention is mainly composed of a dust removal rotary unit 100 and a cover unit 200.

[0030]

The dust-removal rotary part 100 according to the present invention is rotatably rotated by compressed air supplied from the outside, and ejects the compressed air to the outside during rotation.

In more detail, the dust-removing and rotating part 100 includes a rotating body 110 and a rotating shaft 120.

The rotating body 110 is formed in a cylindrical shape, and a receiving space a in which compressed air provided from the outside is temporarily accommodated is formed in the rotating body 110.

Here, the rotating body 110 includes a body 111 and a cap 112.

The body portion 111 is formed in a cylindrical shape having an upper opening and a receiving space a formed therein.

The cap 112 is disposed at the upper end of the body part 111 to seal the upper end of the body part 111. [

At the lower end of the body part 111, a plurality of injection holes 113 for injecting compressed air temporarily supplied to and received in the accommodation space a are formed.

In addition, a rotation hole 112a through which the rotation shaft 120 passes is formed at the center of the cap 112.

The rotation hole 112 a guides the rotation of the rotation shaft 120.

The rotating shaft 120 is formed in a hollow shape and a compressed air supply hole 121 for supplying compressed air to the receiving space a is formed.

The end of the rotating shaft 120 is located in the receiving space a.

Here, the accommodating space (a) is formed so as to be gradually narrowed from the upper end to the lower end of the rotating body 110.

That is, the accommodation space a is formed by the upper space a1 and the lower space a2, and a step is formed between them.

One end of the rotation shaft 120 is positioned in the lower space a2 and the other end is exposed to the outside through the cap 112. [

In the upper space a1, two bearings 300 are disposed.

The two bearings 300 include first and second bearings 310 and 320 for guiding the rotation shaft 120 and the inner wall of the accommodation space a in a rotatable manner in the upper space a1.

A bearing support member 330 is installed between the two bearings 300.

The two bearings 300 guide the rotation of the rotary shaft 120 and the rotary body 110 while keeping the two bearings 300 separated from each other by the bearing support member 330.

In the present invention, the sizes of the two bearings 300 may be different from each other.

In the rotating body 110, a plurality of injection holes 113 are formed around the lower end of the body 111.

The plurality of injection holes 113 may be inclined at an angle to the outside of the body 111 in the receiving space a.

In the cover part 200,

The cover unit 200 includes an upper cover 210 and a lower cover 220.

The upper cover 210 is formed with a fitting hole 211 into which the rotation shaft 120 passing through one side of the rotating body 110 is inserted.

The lower cover 220 is extended from a lower end of the upper cover 210 to surround one side of the rotating body 110 and a part of the outer circumference of the rotating body 110.

The inner surface of the lower cover 220 and the outer surface of the rotating body 110 form a gap.

Next, the operation of the dust filter bleeding apparatus of the present invention constructed as described above will be described.

A dust collector (not shown) provided with a filter cloth is prepared.

The dust filter bleeding apparatus of the present invention is placed inside the filter cloth.

Preferably, the discharge rotation section 100 is inserted into the filter cloth.

Next, the upper cover 210 of the cover unit 200 is detachably connected to an external compressed air supply unit (not shown).

The compressed air supply supplies compressed air having a predetermined pressure to the compressed air supply hole 121 of the rotary shaft 120. The supplied compressed air is supplied to the accommodating space (a) through the compressed air supply hole (121).

The compressed air is temporarily accommodated in the accommodation space (a).

At this time, the compressed air supplied to the accommodation space (a) is injected to the outside through the injection holes (113) formed around the lower end of the body part (111).

At this time, since the ejection holes 113 form an inclination, a rotational force is generated while injecting the compressed air.

Accordingly, the rotating body 110 can be rotated at a predetermined angle with the rotating shaft 120 as the center of rotation.

Next, when the dust collector filter apparatus of the present invention is reciprocated up and down, the dust trapped in the filtration width, including the force of the compressed air and the dust remaining on the surface of the filter cloth due to vibration, can be whipped up.

The dust soaked in the hopper can be removed to the outside.

Through the above-described structure and operation, the embodiment according to the present invention can remove the dust remaining inside and outside the dust collector filter cloth.

In addition, in the embodiment according to the present invention, the dust remaining in the filter cloth can be exhausted without detaching the filter cloth from the dust collector, thereby improving the efficiency in use.

In addition, the embodiment according to the present invention works in a state in which the filter cloth is installed, so that the time and manpower for detaching the filter cloth from the dust collector and connecting them again can be reduced.

In addition, since the filter fabric works in a state where it is installed in the dust collector, there is an advantage that secondary pollution such as dust scattering and wastewater treatment does not occur.

In addition, it is possible to regenerate the filter cloth close to the performance of the new filter cloth, and thus it is possible to control the differential pressure which is the most problematic in the filter cloth filter. Therefore, it is possible to reduce the operating power and the maintenance cost through the maintenance of the low differential pressure as well as the life of the filter fabric.

Although the present invention has been described with respect to specific embodiments thereof, it will be apparent that various modifications may be made without departing from the scope of the present invention.

Therefore, the scope of the present invention should not be limited to the above-described embodiments, but should be determined by the scope of the appended claims and equivalents thereof.

It is to be understood that the foregoing embodiments are illustrative and not restrictive in all respects and that the scope of the present invention is indicated by the appended claims rather than the foregoing description, It is intended that all changes and modifications derived from the equivalent concept be included within the scope of the present invention.
