Therefore, the embodiments described in the specification and the drawings shown in the drawings are only embodiments of the present invention and do not represent all of the technical idea of the present invention, various equivalents that may be substituted for them at the time of the present application It should be understood that there may be variations and variations.

Figure 2 is a cross-sectional view showing a dust removal device according to a preferred embodiment of the present invention.

Referring to the drawings, the dust removing apparatus 100 includes a suction unit for sucking dust, a frame 20 having an inner space S, a discharge pipe 30 installed in the inner space S, and an inner space ( It is provided with an inhaler 40 which sucks dust of S) into the discharge pipe 30 and discharges it to the outside, a reservoir 50 installed under the frame 20, and a moving means for movement.

The suction unit includes a main suction member 10 for sucking floating dust in the air and an auxiliary suction member 16 for sucking dust dropped to the floor. The main suction member 10 preferably has a funnel shape for effective dust suction.

The main suction member 10 is connected to the frame 20 by the first connecting pipe 12. Meanwhile, the main suction member 10 may be supported on the plate 60 by the support member 11.

The main suction member 10 has a funnel shape, and a flange portion 13 may be formed at an edge portion thereof. The flange portion 13 may be installed to be in contact with the inner surface of the tube 1, which prevents the floating dust from moving toward the outlet of the tube 1 without being sucked into the main suction member 10. can do.

The guide member 70 may be installed in the main suction member 10. The guide member 70 is supported by the main suction member 10 by the connecting portion 71. The guide member 70 is installed at the inlet 14 of the main suction member 10 to guide the suction of the floating dust.

Since the guide member 70 has a rhombic cross section, the flow path of the inflow path 15 is wider than the inlet 14 of the main suction member 10. Accordingly, the flow path of the inlet 14 is reduced by the guide member 70, but the suction force at the inlet 14 is increased, so that the floating dust can be sucked with a strong suction force. Once, the suspended dust suctioned through the inlet 14 moves to the first connecting pipe 12 through the inlet passage 15. Since the flow path of the inlet passage 15 is wider than the inlet 14, the pressure loss is reduced. It can be moved to the first connector 12 while being minimized.

The auxiliary suction member 16 is preferably installed in the vicinity of the floor, for example, the bottom surface of the plate 60 in order to effectively suck the dust of the floor. The auxiliary suction member 16 may be connected to the first connector 12 by the second connector 18. In this case, the dust sucked by the auxiliary suction member 16 passes through the second connecting pipe 18 and the first connecting pipe 12 sequentially, and then flows into the inner space S.

On the other hand, the second connecting pipe 18 may be directly connected to the frame 20, in which case the dust sucked by the auxiliary suction member 16 in the internal space (S) through the second connecting pipe (18). It comes in directly.

The suction force of the main suction member 10 and the auxiliary suction member 16 is generated by the inhaler 40, but a separate inhaler (not shown in the drawing) that supplements or replaces the suction force of the inhaler 40. It may be installed in the pipe (12) 18 or the like. The inhalers are devices that generate a suction force by generating a vacuum or suck dust by rotating a fan, and since its configuration is already well known, a description thereof will be omitted.

The frame 20 includes an enclosed inner space S, an inlet 21 connected to the first connecting pipe 12, and an outlet 22 through which dust is dropped down.

The internal space S is a space formed long in the longitudinal direction (y direction). Dust introduced through the inlet 21 falls down while rotating the circumference of the discharge pipe 30 in the internal space (S). Arrows in FIG. 2 exemplarily show a trajectory falling as the dust is rotated.

The inlet 21 is a portion where the first connector 12 and the frame 20 are connected. Therefore, the dust sucked by the main suction member 10 and the auxiliary suction member 16 flows into the internal space S through the inlet 21. The inlet 21 is located above the lower end 31 of the discharge pipe 30, which will be described below.

Discharge port 22 is a portion of the dust is discharged down into the reservoir (50). At the outlet 22, a corrugated pipe 25 may be installed. In addition, in order to effectively discharge the dust through the outlet 22, it is preferable that the lower portion of the frame 20 is formed such that its cross-sectional area is narrowed toward the outlet 22.

On the other hand, the frame 20 may be supported on the plate 60 by an auxiliary frame (not shown), the auxiliary frame supports the frame 20 to facilitate movement and to prevent the frame 20 from shaking. do. Supporting the frame 20 by using the auxiliary frame will be omitted herein because it will be easily understood by those skilled in the art.

The discharge pipe 30 is installed in the longitudinal direction (y direction) in the internal space (S). The discharge pipe 30 is a pipe for sucking some of the dust and air falling down while rotating to discharge to the outside.

The upper end of the discharge pipe 30 is connected to the inhaler 40. In addition, the lower end 31 of the discharge pipe 30 is a portion in which dust and air are introduced, and is located below the inlet 21. Therefore, the suction force of the inhaler 40 sucks dust in the internal space S. Dust and air are introduced into the discharge pipe 30 through the lower end 31 of the discharge pipe 30, and the discharge pipe 30 is It is discharged to the outer tube 35 through the top.

The suction force of the inhaler 40 causes dust and air to flow in the internal space S. Since the lower end 31 of the discharge pipe 30 is located below the inlet 21, the inlet 21 is introduced. As the dust is rotated, it falls down, and some of the dust falling down (small dust) flows into the discharge pipe 30 through the lower portion 31, and the remaining portion (high-mass dust) continues to fall down to the reservoir. Stored at 50.

That is, in the inner space (S), the dust falls down while rotating around the discharge pipe 30, as shown by the arrow of Figure 2, the present invention causes the flow of such dust, heavy dust is stored in the reservoir (50) Fall and light dust is introduced into the discharge pipe (30).

Using this cyclone principle is advantageous because it can process a large amount of dust of 10㎛ or more, and is advantageous to make the dust stored in the storage container 50 into a cake.

The inhaler 40 is installed in connection with the discharge pipe 30. The inhaler 40 generates a suction force so that dust is sucked into the discharge pipe 30 and then discharged to the outside through the external pipe 35.

A filter 37 may be installed in the outer tube 35. The filter 37 removes dust contained in the air and discharges only clean air to the outside. Such a filter 37 can process fine dust and reduce odor. The filter 37 is preferably a replaceable cartridge type.

The filter 37 may be integrally installed on the outer tube 35, but may be modularized to be detachable. That is, the filter 37 may be attached to or removed from the outer tube 35 as necessary, and such a configuration may be easily understood by those skilled in the art with reference to the present specification.

The reservoir 50 is installed below the frame 20. Storage bin 50 stores the dust discharged through the outlet 22 in the storage space (52). A corrugated pipe 25 may be installed between the storage container 50 and the frame 20. The bellows tube 25 may be a commercially available bellows tube, etc. The corrugated pipe 25 may adjust the length between the frame 20 and the storage container 50.

The dust removing apparatus 100 according to the present invention may further include an electromagnet member 54. Electromagnet member 54 may be installed in at least one of the interior space (S) and the reservoir 50, preferably may be installed on the bottom of the reservoir (50).

As is known, an electromagnet has magnetic properties when it is supplied with electricity and loses its magnetism when electricity is cut off. The electromagnet member 54 attaches dust having an iron (Fe) component in the dust using the principle of the electromagnet. Using the electromagnet member 54 can increase the dust adsorption rate and adjust the adsorption performance through the electromagnet.

On the other hand, when the construction to improve the inner surface of large pipes, such as a large-area water pipe, since a lot of dust with an iron component will be generated dust removal device 100 can be effectively used.

The moving means is a means for moving the dust removing apparatus 100. The moving means includes a plate 60 and a wheel 62 installed below the plate 60.

The plate 60 mounts the suction unit, the frame 20, the discharge pipe 30, the inhaler 40, the reservoir 50, and the like. The wheel 62 may be moved by a force pushed by an operator, or may be moved by a separate driving force, for example, a motor.

Meanwhile, the dust removing apparatus 100 according to the present invention may further include a fan 38 connected to the filter 37. The fan 38 may be integrally installed in the exhaust pipe 39, but may be modularized and detachably installed in the exhaust pipe 39.

The fan 38 generates a suction force to assist in the filtering action of the filter 37. The air passing through the fan 38 is discharged to the outside, and is then collected by the exhaust device (EX in FIG. 4). The exhaust device EX may have a dust collecting capacity smaller than that of the existing exhaust device (E in FIG. 1).

As such, since the dust removing device 100 according to the present invention does not use the dust removing filter (6 of FIG. 1), it is possible to solve the problem of replacing the dust removing filter 6 every day, and because it is removable, It is convenient and can effectively remove dust containing a lot of iron without generating air resistance and without causing a problem of backflow of air supply.

In addition, since the filter 37, the fan 38, and the like are modularized and detachable, they can be easily installed or removed as necessary.

Next, a method of removing dust generated during the retrofitting of the wide area water pipe using the dust removing apparatus 100 will be described with reference to FIG. 4. Hereinafter, the present invention will be described using the water pipe 1 as an example, but the scope of the present invention is not limited to the water pipe 1, and is not limited to the place in order to remove dust generated in an enclosed space. Can be used without.

An air supply device SP is installed at the inlet of the water pipe 1 to supply dehumidified air to the inside of the pipe, and an exhaust device EX is installed at the outlet of the water pipe 1 to collect dust. Therefore, the air flow in the direction of the arrow is generated inside the pipe.

On the other hand, when the inner surface of the water pipe 1 is improved by using the rapid construction surface treatment machine 3, a lot of dust, especially dust containing iron (Fe), is generated. On the other hand, since the work is performed by the worker inside the pipe, it is important for the safety of the worker to remove the dust inside the pipe.

The dust floating in the air among the dust generated during the operation is sucked into the main suction member 10 and the dust dropped to the bottom is sucked into the auxiliary suction member 16. The suction of the main suction member 10 and the auxiliary suction member 16 may be performed by suction force generated by the inhaler 40.

Since the main suction member 10 has a funnel shape, it is advantageous to suck dust in the air. The guide member 70 increases the suction force instead of narrowing the flow path of the inlet 14. Since the auxiliary suction member 16 is installed at a position close to the floor, for example, the bottom surface of the plate 60, the suction member 16 can effectively suck dust of the floor.

The main suction member 10 may be installed to face the air flow direction inside the pipe 1 (-x direction) so that the main suction member 10 can effectively suck floating dust in the air. . Since the flange portion 13 is close to the inner surface of the tube 1, the air in the tube can be sucked in most of the main suction member 10.

The dust sucked by the main suction member 10 is introduced into the internal space S through the first connecting pipe 12, and the dust sucked by the auxiliary suction member 16 is connected to the second connecting pipe 18. It passes through the first connecting pipe 12 sequentially and then flows into the inner space (S).

The dust introduced into the inner space (S) falls down while being rotated, and while the dust is falling down, some of the dust (light dust) is introduced into the discharge pipe 30 through the lower end 31 of the discharge pipe 30. The remaining dust (heavy dust and / or iron with iron) is kept falling down and stored in the reservoir 50. At this time, the electromagnet member 54 uses magnetic to effectively introduce the dust having an iron component into the reservoir (50).

The dust introduced into the discharge pipe 30 is discharged to the outside through the inhaler 40 and the external pipe 35. Since the filter 37 installed in the outer tube 35 can remove fine dust, only clean air is discharged to the outside.

The exhaust device EX has a small capacity dust collecting capacity, and collects dust in the air discharged from the outlet of the pipe.

On the other hand, the dust removal device 100 can remove the dust while being moved by the moving means, at this time, the dust removal device 100 moves the dust along the air flow direction (+ x direction) inside the pipe It is desirable to remove.

The dust stored in the storage container 50 is periodically taken out and then pressurized by a press device such as a press to be caked. Cakes are made of lumps of pressed dust. Caked dust is advantageous for transportation and disposal because of its reduced size.
