Description

Cyclone dust collector

The present invention relates to a cyclone dust collector, which introduces polluted air containing dust generated in various working processes into the device, separates and collects the dust through a cyclone process, and further filters fine dust through a HEPA filter It relates to a cyclone dust collector, which prevents the scattering of dust generated when the dust container is replaced and makes it easy to detach the fine dust attached to the HEPA filter.

In general, dust collection from router machines or laser cutting/marking machines performed in clean sites such as electronics factories and automobile factories is mostly accomplished through general cartridge type dust collectors, reverse pulse type dust collectors, or cyclone dust collectors. is losing

In particular, the cyclone dust collector is a device that collects and removes particles of solid or liquid suspended in gas. It is a dust collecting device using the principle that the separation speed from and is increased compared to sedimentation due to weight.

On the other hand, in addition to the router machine or laser cutting/marking machine work process, the dust collector is also used in paint painting work, construction sites, subway vents, etc. Scattering occurs inevitably, and when the dust container is replaced in the work process and work environment that needs to be kept clean, the dust scattering has a bad effect on quality control. In addition, since workers are also exposed to dust, they are reluctant to work, which ultimately leads to a decrease in productivity.

Also, since epoxy powder or copper foil powder of PCB (printed circuit board) generated during routing is finer than flour, etc., there is a serious problem that 30 to 40% of the dust is discharged outside unless a HEPA filter is used. do. In order to solve this problem, a HEPA filter must be used, but from the point of view of an administrator, the filter must be replaced frequently, which causes a real problem in terms of time and cost again.

It is configured to further include a rising flow path 114 to flow, and a second falling flow path 115 to allow the swirling flow passing through the second spiral hole 112 to flow while descending.

The first spiral hole 111 and the second spiral hole 112 serve to allow the air passing through the formed spiral hole to form a swirling flow.

In addition, although not shown, the inner wall forming the first descending passage 113 , the ascending passage 114 , and the second descending passage 115 has a spiral protrusion or groove in accordance with the flow direction of the air passing through the passage. By making this continuous formation, the swirling flow is amplified by moving the air along the spiral projections or grooves so that the cyclonic action is strengthened.

The cyclone dust collection process of the present invention proceeds over two steps, which is shown together in FIG. 1 .

In the first cyclone dust collection step, polluted air containing dust introduced into the inlet 10 (①) descends and turns along the first descending flow path 113 and flows (②), and then flows through the first spiral hole 111 on the upper side (②). ) is a step A in which relatively large and coarse dust is collected by a cyclone in the dust collecting unit 130 on the lower side in the process of inflow (③).

Accordingly, the fine dust contained in the air passing through the cyclone unit 110 is additionally filtered through the HEPA filter 123 , and the purified air passing through the HEPA filter 123 moves upward through the hollow 127 . After that, it is discharged through the outlet 20 .

In addition, on the lower surface of the filter unit 120 along the edge, the air that has passed through the second descending flow path 115 descends and turns and then passes through the secondary cyclone step is introduced and discharged through the hollow 127 to the outside. The hole 128 is formed. The discharge hole 128 may also be formed on the upper surface of the filter unit 120 .

In addition, the filter unit 120 is located in the hollow 127 inside the filter unit 120, while rotating about the rotation shaft 124 on the same line as the motor rotation shaft of the blower 40, the inside of the pleats of the HEPA filter 123 A rotating blade 126 to apply vibration while in contact with 122 is provided.

Allow the dust to dislodge.

Accordingly, it is possible to reduce the cost due to cleaning and replacement of the HEPA filter 123 , and to improve work efficiency because it is not necessary to stop the operation for cleaning and replacement.

Next, the dust collecting unit 130 will be described. The dust collecting unit 130 is configured to collect the dust separated from the contaminated air by the cyclone unit 110 and falling downward.

That is, in the primary cyclone process, polluted air containing dust, which can be said to have a relatively large particle size, descends and turns along the first descending flow path 113 and flows, collides with the inner surface of the case 131, and the dust In the secondary cyclone process, the dust of fine particles descends along the dust collecting pipe 30 extending downward of the inclined surface 116 and is collected in the dust collecting unit 130 .

In addition, fine dust attached to the outer side 121 of the pleats of the HEPA filter 123 and detached by the rotating blade 126 joins the flow descending along the second descending flow path 115, and similarly, the dust collecting pipe ( 30) and is collected in the dust collecting unit 130 .

In addition, an air spraying unit (not shown) is provided on the outside of the dust collecting pipe 30 provided with the damper 50, and spraying air before and after the damper 50 is opened to the dust collecting tube 30 and/or the damper ( 50) Remove fine dust that is not easily separated by being attached to the top.

The dust collecting unit 130 is a case 131 configured to facilitate storage, transport, and internal cleaning of the device 100, and is fitted to the inner surface of the case 131, and a recovery vinyl that enables recovery in a state containing dust. (132).

In addition, it is mounted on the inner lower surface of the case 131, and includes a fixing plate 133 having a fastening hole 134 formed in the center of the circular plate, and the inner lower surface of the case 131 so that the fastening hole 134 is fastened. It is configured to further include a fastening protrusion 135 formed on the.

As the fixing plate 133, a material such as corrugated cardboard may be used, and during operation of the device 100 or during replacement of the recovery vinyl 132, the recovery vinyl 132 mounted inside the case 131 is sucked up and lifted upward. It can be prevented in advance that the separated and collected dust may scatter, be mixed with the air flowing into the first spiral hole 111 again, or be mixed with the purified air that has passed through the hollow 127 due to a pressure difference in a small amount. make it possible

In addition, a differential pressure gauge (not shown) for measuring the differential pressure between the inlet side and the outlet side of the HEPA filter 123 is provided on one side of the filter unit 120 .

In addition, a damper 50 is provided in the dust collecting pipe 30 extending along the inclined surface 116 of the cyclone unit 110 .

The damper 50 closes the dust collecting pipe 30 during the operation of the device 100 and temporarily collects fine dust falling along the inclined surface 116 on the upper surface of the damper 50, but measured by the differential pressure gauge. When the differential pressure is greater than or equal to a predetermined value, the damper 50 is opened, so that the fine dust collected on the upper surface of the damper 50 is discharged to the dust collecting unit 130 on the lower side.

When the damper 50 is opened, the operation of the apparatus 100 is stopped, and it is preferable that the operation of the apparatus 100 is stopped by turning off the power of the blower 40 .

Accordingly, it is possible to automatically know the replacement time of the recovery vinyl 132 in which dust is collected according to the signal of the differential pressure gauge, and it is possible to replace the recovery vinyl 132 in a one-touch method without scattering of the dust.

Meanwhile, the device 100 may be operated with the damper 50 closed for a predetermined time regardless of the differential pressure gauge.
