After producing the high pressure air in the air compressor (43) and supplies the compressed air to the pressure tank through the air inlet pipe (11). The supplied compressed air is temporarily stored in the pressure tank 25, and when the pressure inside the pressure tank 25 rises to a predetermined pressure or more, the air descends rapidly through the discharge pipe 27. By using the pressure tank 25, even if the pressure of the air discharged from the air compressor 43 is not constant, the pressure tank 25 serves as a buffer, so the pressure of the air discharged through the discharge pipe 27 is always constant. maintain.

Compressed air discharged through the discharge pipe 27 reaches the inlet of the venturi unit 29 at a high speed and spreads to a wide space of the first expansion pipe 35, and then temporarily decreases in speed and passes through the central portion 37. The speed increases rapidly. As the speed increases, a negative pressure is generated in the central portion 37, and the negative pressure is transmitted through the second mesh filter 33 through the first expansion pipe 35 to the inner and inner cylinders 17 and the outer cylinder 15 of the upper connection case 19. It is transmitted to the dust inflow pipe 61 through the first mesh filter 31 installed in the space therebetween.

Then, the air containing dust due to the negative pressure transmitted is introduced through the dust inlet pipe 61, and the dust introduced between the inner cylinder 17 and the outer cylinder 15 is heavier than the air and continues straight as shown by arrow A in FIG. While rotating in a spiral, it falls to the dust storage tank 23, and the air passes through the first and second mesh filters 31 and 33 as shown by arrow B in the direction of the venturi unit 29 in which negative pressure is generated. 29) and is discharged with compressed air.

The air passing through the central portion 37 of the venturi unit 29 passes through the second expansion pipe 39, and the silencer 18 is passed through the first pipe 63 and the third pipe 67 with the speed slightly reduced. After entering, it is discharged to the outside.

The second valve 53 installed in the bypass pipe 45 is intermittently opened so that the compressed air is introduced through the bypass pipe 45 and discharged to the nozzle unit 47 so that the first and second mesh filters 31, The dust adhering to 33 is separated by compressed air. The separated dust falls into the dust storage tank 23.

When the air compressor 43 is broken, only the vacuum pump 41 can be driven and used. The air compressor 43 supplies the compressed air by using the air compressor 43 and the vacuum pump 41 at the same time. In 41, the air pressure can be doubled to double the negative pressure.

When only the vacuum pump 41 is used, the fourth valve 57 is closed and the third valve 55 is in an open state. When the vacuum pump 41 is driven, the negative pressure generated by the vacuum pump 41 is transmitted to the venturi unit 29 through the second pipe 65 and the first pipe 63. Therefore, as described above, the negative pressure transmitted to the venturi unit 29 is transmitted to the dust inflow pipe 61 to remove dust in the air.

As described above, the dust separation device 10 of the present invention is a cyclone for generating centrifugal force because dust is separated through the generation of negative pressure through the venturi unit 29, rather than turning the air to separate the dust. Since the installation of the device is unnecessary, it can be miniaturized at the same processing capacity and the manufacturing cost can be reduced compared to the conventional cyclone type dust separation device.

In addition, since the first and second mesh filters 31 and 33 are automatically cleaned by bypassing compressed air, maintenance of the filter is convenient and there is an advantage that the filter can be used semi-permanently.

In addition, the dust separation apparatus 10 of the present invention can use the air compressor 43 and the vacuum pump 41 selectively or simultaneously, so that a large sound pressure can be generated by a small device, so that the dust separation ability is large, one Even if a device fails, the operation of the equipment is less likely to stop suddenly.
