Description
Technical field
The present invention relates to dust arrester technical field, more particularly to a kind of automatic back blow dedusting dust processor.
Background technology
To the dust removal by filtration containing fine dust and gas body in present factory, outside filtering type filter cartridge dust remover typically is used, passes through filter cylinder
The filtering of filter material, dust granules are made to be trapped within filter cartridge appearance, pure air then passes through filter cartridge, so as to reach purification
Effect, in actual use, the easy laying dust dust in filter cylinder surface, so usually using blower fan blowback, the ash that will be bonded on filter cylinder
Blow off, but existing filter cartridge dust remover, the blowback of generally use filter cylinder are rinsed, i.e., pass through multiple companies simultaneously using a pulse valve
Logical nozzle sprays into gas in filter cylinder, but such design have ignored the loss during objectively existing gas is in filter cylinder
Factor, at filter cylinder front end, the stream pressure being blown into filter cylinder is big, and the dust that easily can be adhered to filter cylinder front end is blown out, and is blown
The air-flow for entering filter cylinder rear end can be because the loss of air-flow causes the stream pressure for reaching filter cylinder rear end small and tolerance deficiency, it is impossible to complete
The dust that filter cylinder rear end adheres to is blown off entirely, each filtering cylinder ash cleaning difference on effect can be produced, influence the effective filtration area after deashing,
Filtering cylinder ash cleaning is not thorough, can be because having different position aerations not on filter cylinder when can cause back-blowing device to filter cylinder blowback
Together, filter cylinder deformation can be caused or even be broken, greatly influence the service life of filter cylinder, therefore some existing filter cylinder service lifes
It is short, be exactly for this reason that.
So a kind of automatic back blow dedusting dust processor is needed to solve this problem.
The content of the invention
For the above situation, to overcome the defect of prior art, the purpose of the present invention is just to provide a kind of automatic back blow and removed

9, it is ejected into by the nozzle 10 on thin cylinder 9 in filter cylinder 5, due to the rotation of rotating shaft 7, makes the helicla flute in insertion rotating shaft 7
The direction of inserted link 15 in 12 along helicla flute is slided, and because the upper end of inserted link 15 is connected with fixing axle 14, and is pacified in fixing axle 14
Rolled in track 17 of the roller bearing 16 of dress on the guide rail 12 being fixedly mounted in thick cylinder 8 so that fixing axle 14 can only be in guide rail
It is horizontal on 12 to slide to the left, and fixing axle 14 is connected with thin cylinder 9 so that thin cylinder 9 slides to the left together with inserted link 15,
The nozzle 10 being fixedly mounted on thin cylinder 9 is enabled to reach the position of the most inner side of filter cylinder 5, it is most interior to reach filter cylinder 5 in filter tip 10
In the position way of side, the lasting ejection gas of nozzle 10, the dust for being attached to the outer surface of filter cylinder 5 is blown off because nozzle 10 be
Continue jet into the way of the medial movement of filter cylinder 5 so that 5 each position of filter cylinder can be sprayed the enough gas of pressure by nozzle 10
Stream, can be blown off the dust being attached on 5 each position of filter cylinder with maximally effective.
When nozzle 10 reaches the most inner side of filter cylinder 5, the roller bearing 16 in fixing axle 14 slides into the leftmost of guide rail 14, this
When, fixing axle 14 gives the effect of roller bearing 16 straight up in fixing axle 14 under the elastic force effect of the first spring 18
Power so that be rolled to the high order end of guide rail 12, and moved up along the straightened portion of the vertical direction of guide rail 12, be i.e. fixing axle 14
Move straight up therewith, and drive the inserted link 15 installed in the lower surface of fixing axle 14 to move straight up so that inserted link 15 is de-
From the helicla flute 13 in rotating shaft 7, that is, cause the rotation of rotating shaft 7 that thin cylinder 9 can not be driven to be moved to the left, thin cylinder 9 is rested on the position
Put.
In the presence of the first spring 18 so that roller bearing 16 is lasting on guide rail 12 to move up, when roller bearing 6 reaches rail
During the corner of the top of road 17, roller bearing 16 touches the wedge 29 in guide rail 17, and wedge 29 is headed into groove 28,
When roller bearing 16 leaves wedge 29, wedge 29 returns to original position in the presence of second spring 30, and wedge 29 returns to original position
Afterwards, the resilience in the presence of the first spring 18 of roller bearing 26 can be placed, after roller bearing 16 reaches 17 the top of track, thin cylinder 9 exists
Moved to the right in the presence of extension spring 11, thin cylinder 9 drives the fixing axle 14 being stuck in thin cylinder 9 together to move to the right so that Gu
Tilted direction rolls roller bearing 16 on dead axle 14 to the right in track 17, when thin cylinder 9 returns to original position in the presence of extension spring 11, inserts
Bar 15 is inserted in the helicla flute 13 in rotating shaft 7 and roller bearing 16 reaches the low order end corner of track 17, and roller bearing 16 touches guide rail
Wedge 29 in 17, and wedge 29 is headed into groove 28, when roller bearing 16 leaves wedge 29, wedge 29 is second
Original position is returned in the presence of spring 29, when wedge 29 returns to original position, withstands roller bearing 16 so that roller bearing 16 can not scroll up,
I.e. so that roller bearing 16 can not move to the left from tilted direction, a reverse gas cleaning cleaning is completed.
After filter cylinder 5 comes out the filtering dust in air, dust is fallen into ash bucket 3, when the dust mistake saved bit by bit in ash bucket 3
More, it is necessary to which the dust in ash bucket 3 is cleared, ash bucket switch 31 is opened, you can flow out the dust in ash bucket 3, can carry out
Follow-up processing.
The dust that the present invention can be cleared up effectively in air, when the dust accumulated on filter cylinder is excessive, using flexible anti-
Blowing apparatus, the deep enough filter cylinder of energy, thoroughly blows off the dust being attached on filter cylinder, substantially increases the work effect of dust processor
Rate, the present invention is simple in construction, and ash-removal effect is good, and purification efficiency is high, and processing air quantity is big, safe and reliable to operation, greatly extends
The working life of filter cylinder.
