The present invention relates to a centrifugal dust collector, and more particularly, to separate the collected dust from the air by using centrifugal force and gravity to collect dust in the reservoir and to purify and discharge the air to keep the industrial site clean. By not using the bag filter of the existing dust collector, there is no phenomenon that the bag filter is clogged by the dust during dust collection, so there is no need to clean or replace the bag filter frequently. The present invention relates to a centrifugal dust collector capable of reducing power consumption due to low power consumption.

In general, particulate matter (floating dust) is one of the important air pollutants and occurs naturally or artificially.

Most naturally occurring particles are more than 2.5 microns, and are mainly produced by wind-based soil dust and mechanical grinding processes such as sea salt particles.

On the other hand, artificially generated suspended dust is a particle of less than 2.5 microns, which is generated in a large amount during chemical combustion, automobile emissions and chemical manufacturing.

The formation of particulate matter is also produced by the gaseous material, the gaseous material increases from the molecular size to the size of the microparticles through the condensation and aggregation process.

This phenomenon not only increases the particle size but also contains harmful sulfurous acid gas and volatile organic compounds, which is more lethal to the human body.

Particle sizes emitted from contaminants vary widely, and the hazards of the human body vary greatly depending on the size distribution of the particles and what chemicals they bind to.

The above-mentioned suspended dust is generated in many factories in steel mills, automobile manufacturing plants, ship manufacturing plants, industrial machinery manufacturing plants, thermal power plants, incinerators, and the like. It is installed and used.

Therefore, definitions of these terms should be made based on the contents throughout this specification.

1 is an internal view of a centrifugal dust collector according to an embodiment of the present invention, Figure 2 is a cross-sectional view of the centrifugal separator of the centrifugal dust collector according to an embodiment of the present invention.

Figure 3 is a schematic diagram showing a filter replacement state of the centrifugal dust collector according to an embodiment of the present invention, Figure 4 is a perspective view showing a filter replacement frame of the centrifugal dust collector according to an embodiment of the present invention. .

Referring to FIG. 1, the centrifugal dust collector according to an embodiment of the present invention includes a main body 10, a centrifugal separation member 20, a discharge induction pipe 30, and a filter member 40.

The main body 10 includes a centrifugal separation member 20, a discharge induction pipe 30, and a filter member 40, and forms an external shape of the dust collector. Of course, the body 10 is applicable to a variety of shapes and materials.

In particular, the body 10 has a hood 12 and an outlet 14. The hood 12 serves to guide the contaminated air containing foreign matter, and the outlet 14 serves to guide the purified air to the outside of the main body 10 by removing the foreign matter.

At this time, the air containing the foreign matter is forcibly introduced through the hood 12, or the purified air is forcibly discharged through the discharge port (14). That is, any one of the hood 12 and the outlet 14 is provided with a fan (not shown). Accordingly, the flow of air naturally occurs.

On the other hand, after the air is introduced into the body 10, in particular the centrifugal separating member 20 through the hood 12, the hood 12 is the main body so as to be discharged through the discharge port 14 in the state to drop the foreign matter as much as possible It is provided on the circumferential surface of 10, the discharge port 14 is preferably provided on the upper side of the main body (10).

In addition, the hood 12 in which the contaminated air is introduced and the purified air is discharged is provided at one side of the main body 10, and the discharge port 14 is provided at the other side of the main body 10. Here, the hood 12 is formed in a variety of shapes, it is preferable that the main body 10 and the centrifugal separation member 20 is provided to be detachable.

In addition, the centrifugal separation member 20 is provided inside the main body 10 and is connected to the hood 12 to naturally induce vortices in the introduced air to serve to induce foreign matter to primarily fall.

That is, the centrifugal separating member 20 is provided to be connected to the hood 12 to receive the air including the foreign matter introduced therein. At this time, the air is forced into the centrifuge member 20 to form a vortex.

Accordingly, as air forms a vortex inside the centrifugal separation member 20, the foreign material primarily induces a drop of foreign matter.

And, the discharge induction pipe 30 is provided on one side of the centrifugal separation member 20 serves to discharge the primarily purified air.

More specifically, the discharge induction pipe 30 serves to guide the first purified air to the discharge port 14 by opening the sealed centrifuge member 20 toward the discharge port 14.

That is, the discharge induction pipe 30 is connected to the upper side of the centrifuge member 20, it is installed to extend into the centrifuge member 20. Accordingly, the air introduced into the centrifuge member 20 through the hood 12 forms a vortex and flows in the downward direction and then moves toward the outlet 14 through the discharge induction pipe 30.

On the other hand, the filter member 40 is provided to correspond to the outlet 14 to pass the air discharged from the discharge induction pipe 30 and serves to purify secondary.

Here, 'corresponding to the outlet 14' means that the filter member 40 is provided on the upper side or the lower side of the main body 10 to be fitted to the inner side of the outlet 14 or to cover the outlet 14. do.

The filter member 40 may apply various filters having a dust collecting function.

Particularly, if the primary purified air passes through the filter member 40 directly through the discharge induction pipe 30 while the flow is forcibly generated, the air passes through the filter member 40 and noise is generated by a large flow resistance. A large amount of oil may be generated, and the filter member 40 may be hardly hit and the filter member 40 may be damaged, and the replacement period of the filter member 40 may be shortened by the remaining foreign matter.

Thus, a collection guide member 60 is further provided between the discharge induction pipe 30 and the filter member 40.

The collection guide member 60 is formed to be bent a plurality of times to convert the flow of air passing through the discharge induction pipe 30. Thus, by passing through the filter member 40 after the air loses a lot of kinetic energy, the filter member 40 is not damaged and reduces noise caused by the air passing through.

In addition, the collection guide member 60 has a space for temporarily storing the air passing through the discharge induction pipe 30 serves to guide the supply to the filter member 40 in a stable and stable manner. As a result, the filter member 40 can maintain a constant dust removal rate of the air supplied by metering.

At this time, the collection guide member 60 is supported and fixed in the body 10 or the discharge induction pipe 30, it is applicable to a variety of shapes and materials.

In addition, the centrifugal separating member 20 includes an upper separating member 22 and a lower separating member 24.

The upper separation member 22 is connected and fixed inside the main body 10, is directly connected to the hood 12, and connects the discharge induction pipe 30 to the upper side, made of a tubular shape of the same diameter.

At this time, the upper separating member 22 is fixedly installed in the main body 10 in various ways, and inserts the hood 12 on the upper circumferential surface. At this time, the upper separation member 22 seals the upper side except for the portion opened by the discharge induction pipe (30). Thus, the air introduced into the upper separation member 22 through the hood 12 forms a vortex and generates a downward flow toward the lower separation member 24.

As a result, foreign matter contained in the air primarily falls naturally.

In particular, the upper separation member 22 is preferably formed to have the same diameter in the height direction in order to impart the maximum centrifugal force to the air to be forced into the vortex generated.

In addition, the lower separating member 24 extends to the lower side of the upper separating member 22, and has a shape in which the diameter gradually decreases toward the lower side.

The reason the diameter of the lower separating member 24 decreases toward the lower direction is to induce the drop of foreign matter as much as possible by continuously forming a vortex in a space where the air whose rotation speed decreases gradually decreases compared to the inside of the upper separating member 22. To do this.

At this time, the upper separation member 22 and the lower separation member 24 may be formed integrally, or may be provided detachably.

In particular, the air in the lower portion of the lower separating member 24 rises along the center of the centrifugal separating member 20 and flows toward the discharge induction pipe 30.

Here, the discharge induction pipe 30 is preferably made of a length extending to a position corresponding to the inner side of the lower separating member 24 is connected to the upper side of the upper separating member (22).

This is to allow the air causing the vortex inside the upper separation member 22 to drop the foreign matter as much as possible by centrifugal force and then move to the filter member 40 through the discharge induction pipe 30.

At this time, the discharge induction pipe 30 is connected to the upper side of the upper separation member 22 in various ways.

In addition, the centrifugal separation member 20 is provided with a spiral centrifugal projection 26 on the upper inner surface, the hood 12 is preferably installed to be inclined with respect to the tangential member 20.

That is, as shown in Figure 2, the upper separation member 22 protrudes to form a centrifugal separation projection 26 in a spiral coil shape on the inner side. Thus, air is forced to flow along the centrifugal projections 26 to form a vortex.

In addition, the hood 12 is connected to the upper separating member 22 to be inclined with respect to the direction perpendicular to the tangent of the upper separating member 22. As a result, the air flowing through the hood 12 is forcibly moved toward the centrifugal projection 26. Therefore, the air naturally forms a vortex inside the upper separation member 22.

At this time, the centrifugal projection (26) may be formed integrally with the upper separation member 22, it may be provided detachably.

And, the centrifugal separation member 20 is preferably provided with a foreign matter storage container 70 on the lower side.

That is, the lower separating member 24 is preferably provided with a foreign matter storage container 70 containing the foreign matter falling naturally. At this time, the foreign matter storage container 70 is preferably detachably coupled to the lower separation member 24 to discard the foreign matter. Here, the foreign matter storage container 70 may be detachably coupled to the lower separation member 24 by various methods.

On the other hand, as shown in Figures 1, 3 and 4, the main body 10 is preferably provided with a frame 50 that can slide the filter member 40 on the other side corresponding to the outlet (14).

In other words, the filter member 40 is slide-inserted into the frame 50 having a planar rectangular frame or polygonal frame shape. Thus, the frame 50 is provided to open and close one side. One way of opening and closing one side of the frame 50 can be applied in various ways. Of course, the frame 50 is applicable to a variety of shapes and materials.

The frame 50 on which the filter member 40 is mounted is coupled to the upper side of the main body 10 by various methods such as bolting.

Here, the frame 50 is coupled to the upper side of the main body 10 along the edge of the discharge port (14).

As a result, the outside air is introduced into the centrifuge member 20 through the hood 12 to filter out foreign matter primarily while causing vortices, and secondly while passing through the discharge induction pipe 30 to the filter member 40. The foreign material is filtered out.

At this time, the foreign matter that hits the filter member 40 is stored dropped into the collection guide member 60 or introduced into the foreign matter storage container (70).

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. I will understand. Therefore, the true technical protection scope of the present invention will be defined by the claims below.
