Description
Technical field
The present invention relates to negative pressure dust removing device with quantitative automatic ash-discharging device, belongs to dust arrester technical field.
Background technology
Dust collection device installs unloading valve to control ash discharge in ash discharging hole, and preferable unloading valve should ensure effective ash discharge, again
Prevent outside air from influenceing internal wind flow field through unloading valve suction dust pelletizing system.It is uncharged for explosive dust, use
Ash-discharging device advantageously reduces accident risk, such as manual star, board plug type, drawer type, automatic turnover type unloading valve.Wherein
Star-shaped ash unloading valve is because the advantages that ash hole is small, sealing is high, is most widely used, but star-shaped ash unloading valve once falls into rigid board
Material easily blocks, while generally requires with the larger back taper ash bucket in unification inclination angle, and this considerably increases the body of ash-discharging device
Product.Board plug type take up space it is small, but need it is frequently manually operated, produce larger labor intensity, especially unloading ash not
Sufficiently under the conditions of, plate can not normal return, easily influence unloading valve sealing.Drawer type unloading valve is the most reliable and steady
It is fixed, higher sealing property can be realized, but mechanization and automaticity are too low, and labor intensity is maximum.Automatic turnover type unloads ash
Valve, can under the conditions of dust weight is set automatic removing dust, but to ensure that sealing can be reduced while turnover panel flexibility, and
And turnover plate type unloading valve mechanical component is more, complicated, fault rate is high under dust atmosphere.

Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
As shown in Figures 1 to 4：The present invention includes dust collector box body 1 and the He of filter core 2 inside dust collector box body 1
Deashing device 3, in addition to flexible sealing plate 4, dust block board 5, rigid seal plate 6, crossbeam 7 and quadrangle expansion bracket 8；Deduster case
Body 1 is provided with air inlet and gas outlet, and deashing device 3 is arranged on the top of dust collector box body 1, and dust block board is located at dust collector box body 1
Bottom, filter core 2 are arranged between deashing device 3 and dust block board 5；
Flexible sealing plate 4 and rigid seal plate 6 are separately fixed at the both sides of dust block board 5, and the top of dust block board 5 is fixed on crossbeam 7
On, the hinge axis of the bottom of quadrangle expansion bracket 8 is connected with crossbeam 7, the hinge axis difference of the both side ends of quadrangle expansion bracket 8
It is fixed on dust collector box body 1 and piston 11；The both ends of crossbeam 7 are arranged in the slideway 9 opened up on dust collector box body 1；
The bottom side of dust collector box body 1 is provided with empty van 12, and piston 12 is provided between empty van 12 and dust collector box body 1, living
Regulating valve 13 is connected with plug 12.
In order that dust collector box body 1 is internally formed good vacuum effect, dust block board 5 and rigid seal after deduster is opened
Space between plate 6 and dust collector box body 1 is sealed by sealing gasket 10.
The quadrangle length of side of the unit of quadrangle expansion bracket 8 is equal, and each side is connected through the hinge, so, four sides
Shape expansion bracket 8 is stretched with contraction process, and every group of flexible sealing plate 4 and rigid seal plate 6 are equidistant, namely each group flexibility is close
The distance between shrouding 4 and rigid seal plate 6 add on an equal basis.
In order that flexible sealing plate 4 plays more preferable effect when working, the rigid seal plate 6 is to flexible sealing plate 4
Direction tilts, and rigid seal plate 6 is 3 ° -10 ° with vertical direction inclination angle scope, it is preferable that 5 °；The length of flexible sealing plate 4
For 10-30cm, and folding material flexible using lightweight.
In use, dust collector box body 1 is internally formed negative pressure to the present invention after deduster is opened, and dust enters from air inlet
Enter, under negative-pressure sucking effect, flexible sealing plate 4 is attracted on rigid seal plate 6, and dust collector box body 1 realizes sealing；Dedusting
Dust is trapped by filter core 2 in the device course of work, and the dust being captured is cleared up by deashing device 3 and falls into dust collector box body 1 successively
On bottom compliant sealing plate 4, when the dust weight of deposition is more than the suction function that flexible sealing plate 4 is subject to, flexible sealing
Plate 4 is separated with rigid seal plate 6, and dust is automatically fallen into the bottom of dust collector box body 1 by Action of Gravity Field, is then transported away.
Now, the flexible sealing plate 4 overstock without dust is adsorbed in rigid seal plate 6 again, and dust collector box body 1 recovers close again
Envelope state.
The flexible sealing plate 4 for being connected to same dust block board 5 and rigid seal plate 4 are considered as one group, the present invention can pass through four
Unfolding and shrinking for side shape expansion bracket 8 adjusts the distance between every group of flexible sealing plate 4 and rigid seal plate 6, to adjust flexibility
The threshold value that sealing plate 4 is closed and opened.When adjustment, which occurs, for deduster operating mode causes internal negative pressure to change, for example negative pressure increases
Add, piston 11 can be pulled outward by regulating valve 13, quadrangle expansion bracket 8 is stretched, and is arranged on by crossbeam 7 and dust block board 5
The distance between every group of flexible sealing plate 4 and rigid seal plate 6 on quadrangle expansion bracket 8 increase.Due to quadrangle expansion bracket 8
The equal length on the quadrangle side of each unit, and each side is connected through the hinge, therefore, quadrangle expansion bracket 8 is stretched
During, every group of flexible sealing plate 4 and the also equidistant increase of rigid seal plate 6, namely each group flexible sealing plate 4 and rigid seal
The distance between plate 6 adds on an equal basis.Now flexible sealing plate 4 can just be attracted to rigid seal under bigger negative-pressure sucking
On plate 6, to adapt to increased deduster suction function.
Opened when needing in less deposition dust weight and unload ash, can pushed away piston 11 inside by regulating valve 13,
Quadrangle expansion bracket 8 is compressed, and the distance between each group flexible sealing plate 4 and rigid seal plate 6 reduce, therefore flexible sealing plate
The 4 negative pressure areas being subject to are less, and suction function is smaller, and the weight for the maximum dust that flexible sealing plate 4 can be born also becomes
Change, flexible sealing plate 4 will be opened in the dust weight less deposited and unload ash.In this way, that is, setting powder is realized
The automatic ash-discharging of dirt ash weight.
