Dust collecting cabinet 313 is used for the chip for collecting the filtering of screen pack 316.It is the dust that is carried in gas, broken after gas is by dust total pipeline
Bits enter the first dust arrester, and screen pack 316 is by Chip entrapment of the particle diameter more than 20 μm, and these massive waste materials are with regard to direct
The first collection cabinet of lower section is dropped to, the dust less than 20 μm that gas carries then continues to move into the second dust arrester.
Further, the first dust arrester also includes the first disposal box 311, and screen pack 316 is arranged on the first disposal box 311
In.First disposal box 311 is provided with the first air inlet 314, the first gas outlet 315 and the first dust mouth 312, the first air inlet
314 and first gas outlet 315 respectively be located at screen pack 316 both sides, the first dust mouth 312 and the first air inlet 314 were located at
The homonymy of filter screen 316 simultaneously states the lower section that the first dust mouth 312 is located at the screen pack 316, the first dust collecting cabinet 313 removably with
First dust mouth 312 connects.
Alternatively, screen pack can be the filter bag of rigid filter screen or flexibility.
Alternatively, the second dust arrester includes filter core 326, the dust collecting cabinet 323 of air accumulator 327 and second, the second dust collecting cabinet 323
It is arranged on the dust that the lower section of filter core 326 is used to collect the filtering of filter core 326；Air accumulator 327 is used to be vented to the pulse of filter core 326.It is small
Dust, chip in 20 μm enter the second dust arrester, are adsorbed on filter core 326.Wherein, filter core 326 can be as needed,
Select suitable filtering accuracy.Filter core 326 can retain 5 μm of dust can substantially.
Air accumulator 327 discharges first compression air to the direction of filter core 326 at regular intervals, blown built with compressed air
Fall dust of the absorption on filter core 326.0.50 μm to 20 μm of dust is fallen into the second collection cabinet, is realized to different-grain diameter
Dust, the separated centralized collection of chip.Further, chip, the dust for separating centralized collection are separately handled, due to separated receipts
Chip, the dust of collection are formed by different handling process respectively, and its composition is different, are advantageous to after separate collection for difference
The separated recycling of the chip, dust of composition.
Alternatively, air accumulator is outwards blown by pipeline with being connected inside filter core from filter core inside, so that absorption is being filtered
Dust on core departs from, and avoids blocking filter core.

The dust mouth 322 of dust mouth 312 and second, funnel-form are shape wide at the top and narrow at the bottom.Funnelform structure can make chip or dust
Smoothly enter in the first dust collecting cabinet 313 and the second dust collecting cabinet 323, while avoid the first dust collecting cabinet 313, the second dust collecting cabinet 323
In chip or dust backflow into the first disposal box 311, the second disposal box 321.
Further, also include wind pipe suitable for the central dust-collection system of wiring board difference workshop dedusting demand, go out
Wind pipeline is connected on the second dust arrester, for discharging the air after filtering.Purification air, Ke Yizhi are discharged via wind pipe
Run in into air, workshop can also be discharged into, fresh air is provided for workshop.
In an optional embodiment, air blower or ventilation blower are arranged on wind pipe 400.
Further, some dust suction branch pipe(tube)s are respectively equipped with branch pipe valve.Branch pipe valve can be switched and can also adjusted out
Degree.
Further, wind pipe 400 is multiple that multiple wind pipes 400 are provided with air transporting arrangement 500 entirely.With going out
The second connected dust arrester of wind pipeline 400, it is multiple to be provided with gas because the driving force needed for the smaller grade of the dust size of filtering is larger
The wind pipe 400 of conveying device 500 can make up this deficiency.
Further, multiple wind pipes 400 are all connected with an air-out total pipeline.The use of air-out total pipeline can be with
Pipeline spending is saved, is saved and is taken up an area, is easy to lay, also the convenient air by after filtering is discharged.One air-out total pipeline compared to
Multiple wind pipes 400 are more efficiently.
A kind of application method of the above-mentioned central dust-collection system suitable for wiring board difference workshop dedusting demand is as follows：
Step 1：Some dust suction branch pipe(tube)s in installation or borrow board, are pooled to the dust suction total pipeline 200 that internal diameter is 80mm.
Step 2：The dust of workbench or chip are sucked by dust suction branch pipe(tube) using air blower.
Step 3：By dust suction total pipeline 200, dust, chip enter the first dust arrester, will be super by screen pack 316
20 μm of big Chip entrapments are crossed, massive waste material directly drops to collection cabinet, and less than 20 μm dust pass through the first dust arrester.
Step 4：Dust, chip less than 20 μm enter the second dust arrester, are attracted on filter core 326.
Step 5：The each air-breathing of air blower stops suction 1 minute after 12 minutes, now discharges and compresses from air accumulator 327
Air, the dust adsorbed on filter core 326 is blown off.5 μm to 20 μm of dust is fallen in the second dust collecting cabinet 323.
Step 6：First dust collecting cabinet 313, the second dust collecting cabinet 323 are separately handled according to the collecting amount of chip, dust.
For suction system or dust exhaust apparatus on the central dust collector of the embodiment of the present invention, with traditional board, possess
Advantages below：
The dedusting simultaneously of different workshops can be met；Effective categorised collection dust, chip the like waste, can separate and be handled, be located
Air after reason can be discharged directly.
Can continuous non-stop run in 24 hours, suction is powerful, storage dirt volume is big, service life is long, can high temperature resistant, Ke Yiyou
Effect prevents the harm of some dust occupational diseases, physically and mentally healthy beneficial to employee.
Filter core 326 is adjusted, and can be improved filtering accuracy up to 0.5 μm, additionally can subsequently be improved；Board safety operation,
Product quality is more secure.
In the present description, term " first ", " second " are only used for describing purpose, and it is not intended that instruction or hint
Relative importance.
Embodiment described above only expresses the several embodiments of the present invention, and its description is more specific and detailed, but simultaneously
