The present invention can be applied to various kinds of dusts which are harmful to the human body contained in the air in the workshop 800 by using the double cyclone generating dust collectors 100-1 to 100-n of compressed air sucking type dispersed in the dust collecting induction parts 300, Clean air that has been purified through separation and removal processes of pollutants 810 such as moisture, oil, dust, flour, rubber powder, organic compounds, etc. is discharged to the outside.

The above-mentioned cyclone refers to separating and collecting various kinds of abnormal phase particles contained in a fluid through a swirling flow, by centrifugal force.

As shown in FIGS. 1 and 2, the present invention is divided into an indoor side and an outdoor side based on the wall surface of a building, and includes, for example, Dust collecting guides 300 and 300a for guiding the contaminants 810 to the dust collectors 100-1 to 100-n through the suction unit 200 are constructed.

The suction unit 200 may be formed in a trumpet shape so as to allow the contaminant 810 to be sucked in the front end of the dust guide unit 300 or 300a. It may be desirable to facilitate the inhalation action on various contaminants 810.

In addition, as a means for further enhancing the suction force of the pollutant 810 according to the environment of the workshop 800, an auxiliary dust collecting fan (Fan) is installed at a portion where the dust collecting inducing parts 300 and 300a are connected to the suction part 200, A preliminary dust collecting unit 210 or a filter may be installed at the front end of the auxiliary dust collecting fan 220 to filter the contaminants 810 having a relatively large volume in advance It may be preferable to prevent the inflow pipe 114 from being clogged.

The dust collectors 100-1 to 100-n are connected to the inlet 111 through an inlet pipe 114, which is disposed in the dust collecting guides 300 and 300a. It is preferable that the dust collectors 100-1 to 100-n are connected to the dust collecting guides 300 and 300a one by one through the inflow pipe 114. At this time, the environment of the work site 800, The number of the inlet pipes 114 may be adjusted depending on the type and amount of the contaminants 810, the concentration of the contaminants 810, and the like.

Control valves 600-1 through 700-n that are opened and closed by the control unit 600 to control the inflow and outflow of the compressed air are provided in the inflow pipe 114 distributed to the dust guide units 300 and 300a. The control valves 700-1 to 700-n are arranged such that the contaminants 810 already flowing into the dust collectors 100-1 to 100-n flow back to the dust collecting guides 300 and 300a And a check valve for controlling the one-way flow.

In addition, the control valves 700-1 to 700-n are individually opened / closed by the control unit 600 according to the environment of the workshop 800, that is, the size of the area, the type and amount of the pollutants 810, So that the pollutants 810 are introduced into or blocked from the dust collectors 100-1 to 100-n.

The pollutants 810 connected to the outlets 112 of the dust collectors 100-1 to 100-n through the outflow pipe 115 and flowing from the dust collecting guides 300 and 300a to the dust collector 100 -1 to 100-n, an air suction unit 500 for generating suction compressed air is constructed.

The air suction unit 500 is controlled by the control unit 600 to adjust the intensity of the suction compressed air generated depending on the environment of the work site 800, that is, the size of the area, the type and amount of the pollutant 810, .

The contaminants 810 introduced into the dust collectors 100-1 to 100-n together with compressed air are generated in the first chamber 122 and the second chamber 123 provided in the cyclone generating unit 120 And the discharge port 113 is separated and discharged from the compressed air by the centrifugal force.

400-1 to 400-n where the pollutants 810 discharged through the discharge pipe 116 connected to the discharge port 113 are collected, Depending on the environment of the workshop 800, as shown in FIG. 1, a plurality of discharge pipes 116 may be integrally installed in one location to collectively treat the pollutants 810, The bottoms 400-1 to 400-n may have another structure in which one discharge pipe 116 is installed separately to treat the pollutants 810 individually.

The compressed air from which the pollutants 810 are separated passes through the outlet pipe 115 connected to the outlet 112 of the dust collectors 100-1 to 100-n through the air suction unit 500, And an exhaust unit 510 for exhausting the exhaust gas.

Next, the construction of the dust collectors 100-1 to 100-n included in the present invention will be described in detail with reference to FIGS. 3 to 7 attached hereto.

The dust collectors 100-1 to 100-n include a cyclone generating unit 120 for generating a cyclone in succession in the first chamber 122 and the second chamber 123, A drain portion 140 for discharging contaminants 810 in the workplace 800 through an outlet 113 and a coupling portion 130 for coupling the cyclone generating portion 120 and the drain portion 140 to each other, .

The dust collectors 100-1 to 100-n are arranged such that the compressed air having the suction force generated in the air suction unit 500 flows through the suction unit 200, the dust guide unit 300, 300a, and the inflow pipe 114 The compressed air passing through the inlet port 111 and the cyclone generating section 120 flows out to the outlet pipe 115 through the outlet port 112.

The cyclone generating unit 120 included in the dust collectors 100-1 to 100-n includes a first chamber 122 communicating with the inlet 111 and a cylindrical outer cylinder 120 surrounded by the first chamber 122. [ And a second chamber 123 communicating with the outlet 112 through an exhaust pipe 124 through which the compressed air is discharged and purified air surrounded by the inner cylinder 126 and the exhaust pipe 125, ).

In other words, a coupling part 121 communicating with the outflow port 112 is formed at the inner upper end of the body 120a provided in the cyclone generating part 120, and the coupling part 121 is connected to the center of the outer cylinder 124 So that the purified air compressed in the exhaust pipe 125 is discharged to the outlet 112.

In addition, the inner cylinder 126 provided between the outer cylinder 124 and the exhaust pipe 125 is formed into a conical shape so as to have a reduced diameter toward the drain portion 140.

The drain 140 communicates with the first chamber 122 and the outer cylinder 124 through a space 141a formed in the upper side of the body 140a and compresses And an upper collection chamber 142 for collecting the pollutants 810 separated from the air.

5, the upper end of the outer tube 124 is provided with a first guide portion 127a having a wing shape so that compressed air can be discharged in a tangential direction along the periphery thereof, 128a are arranged at regular intervals.

For example, the width of the first flow path 128a may be made narrower in the counterclockwise direction, thereby rotating the compressed air flowing from the upper end of the outer tube 124 through the first flow path 128a And the air flows into the first chamber 122 provided between the outer cylinder 124 and the body 120a while flowing downward.

6, a second flow path 128b (see FIG. 6) is provided between the second guide portion 127b having a wing shape through which compressed air can be discharged in a tangential direction along the periphery thereof, ) At regular intervals.

For example, the width of the second flow path 128b may be made narrower in the clockwise direction, so that the compressed air flowing from the upper end of the inner tube 126 may be again drawn through the second flow path 128b And is caused to flow into the second chamber 122 provided between the inner cylinder 126 and the exhaust pipe 125 while being swirled downward.

In the cyclone generating unit 120 of the present invention, the compressed air flows downward while circulating in the first chamber 122. In this process, the contaminant 810 is separated from the compressed air primarily by the centrifugal force And is pushed against the inner wall of the body 120a.

The contaminants 810 separated from the compressed air descend along the inner wall of the body 120a of the cyclone generating unit 120 and the inner wall of the body 140a of the drain 140 Which is collected in a lower collection chamber 150 communicating with the first chamber 122 through a space between the flanges 143 formed to be smaller than the inner diameter of the body 140a.

Since the diameter of the outer cylinder 124 is relatively larger than the diameter of the inner cylinder 126, the pivoting motion generated in the first chamber 122 is less than the pivoting motion generated in the second chamber 123 It becomes low speed. Accordingly, a large amount of moisture, oil, and large foreign substances are separated from the contaminant 810 that is primarily separated from the first chamber 122.

The compressed air in which the contaminant 810 is primarily separated flows upward again along the space 141b between the outer cylinder 124 and the inner cylinder 126, And flows into the second chamber 123 by the swirling movement while passing through the flow path 128b.

In the meantime, since the inner cylinder 126 of the present invention has a conical shape that gradually decreases as the diameter of the inner cylinder 126 decreases, the swing motion in the second chamber 123 accelerates gradually as it goes down .

In other words, since the second chamber 123 has a structure in which the interval between the inner cylinder 126 and the exhaust pipe 125 is narrowed, the cross-sectional area through which the compressed air passes becomes smaller as it is lowered, The centrifugal force is accelerated by accelerating the revolution speed of the compressed air between the inner cylinder 126 and the exhaust pipe 125 to increase the centrifugal force.

Accordingly, the compressed air in the second chamber 123 can not be separated from the first chamber 122 due to a slight amount of moisture, which can not be separated from the first chamber 122, while moving downward at a high speed as indicated by an arrow about the exhaust pipe 125 The pollutant 810 containing oil and small foreign matter is further separated from the compressed air to increase the air purification efficiency.

As described above, according to the present invention, by accelerating the compressed air flowing into the inlet 111 from the first flow path 128a and the second flow path 128b twice, The separation to the contaminant 810 is made more efficient.

On the other hand, the contaminants 810 are separated from the compressed air by centrifugal force and collide with the inner wall of the inner cylinder 126 to descend and collect in the lower collection chamber 150.

The clean compressed air in which the contaminant 810 is separated from the second chamber 123 is cleaned by the outlet pipe 115 connected to the outlet 112 and the air And is exhausted to the outside through the exhaust part 510 through the suction part 500.

An elastic member 144 having an elastic force is disposed on the upper portion of the pressure blocking portion 145 in the drain trapping chamber 142 formed integrally with the drain pipe 140 at a lower portion of the inner pipe 126, The open upper part of the collection chamber 142 communicates with the second chamber 123, and the pollutant 810 separated from the second chamber 123 falls and is collected.

The lower part of the upper collecting chamber 142 is formed with a discharge part 147 having a hole 146 communicating with the first chamber 122 and the space 141a.

In addition, the inside of the discharge portion 147 is communicated with the space 141a and the lower collection chamber 150 through the hole 146. When the hole 146 is opened, the lower collection chamber 150 Compressed air flows into the discharge portion 147 through the hole 146. [

The pressure blocking portion 145 inserted into the upper collecting chamber 142 opens and closes the hole 146 by the pressure difference between the space 141a and the upper collecting chamber 142, And discharges the contaminants 810 to the discharge port 113 by opening and closing the discharge pin 148 sliding up and down by the elastic force of the elastic body 151. [

On the other hand, in the drain part 140, the inside of the upper collecting chamber 142 is lifted and lowered by a pressure difference between the first chamber 122 where the high pressure is generated and the second chamber 123 where the low pressure is generated, The discharge port 145 of the discharge port 147 opens and closes the hole 146 to open and close the discharge pin 148 provided in the discharge port 147 to discharge the pollutant 810 to the discharge port 113 .

Reference numeral 152 denotes a disk which is in close contact with the inner circumferential surface of the discharge portion 147 to block vertical communication. Reference numeral 153 denotes an inlet (not shown) through the hole 146 when the discharge pin 148 descends Is discharged to the discharge port (113).

Further, a discharge groove 149 is formed at the lower end of the discharge portion 147 at regular intervals along the periphery thereof, and is communicated with the lower collection chamber 150 through the discharge groove 149. Accordingly, the pollutants 810 collected in the lower collecting chamber 150 are introduced into the discharging part 147, which is discharged to the lower part 400, 400-1 through 400-1 through the discharge pipe 116 connected to the discharging port 113, 400-n, respectively.

As described above, according to the present invention, the first chamber 122 and the second chamber 123 provided in the cyclone dust collectors 100-1 through 100-n provided in the dust collecting induction units 300 and 300a, And thus separates the pollutants 810 from the compressed air twice. Therefore, the air purifying capability of the workplace 800 is further improved.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention.

Accordingly, the technical scope of the present invention should be defined by the claims of the present invention, not limited to the inner bar described in various exemplary embodiments as mentioned above.
