Body 9 is interference fitted, and is provided with inner hole on the partition 10, mechanical ash removing pipe is provided on the partition of the inner hole lower end, described
Mechanical ash removing bottom of the tube and 8 upper end of filter core are tightly connected；9 upper end of dust-removing box is provided with injection tube 2, the injection tube 2
It is connect with pulsation gas source, 2 lower end of injection tube place corresponding with 8 vertical position of filter core is provided with nozzle 1, passes through spray
Mouth 1 is to 8 pulse jet of filter core, so that mechanical ash removing pipe does mechanical motion, the dust of tube core outer wall is shaken off.
The mechanical ash removing pipe includes spring 11, bolt 12, rubber sleeve 13,10 two sides of the partition setting of the inner hole outer ring
There are two bolt hole, it is provided with bolt 12 in the bolt hole, the stud base is fixedly connected with 11 upper end of spring, the bullet
11 lower end of spring is fixedly connected with 8 upper end of filter core, is provided with rubber between the filter core 8 and partition 10 of 11 two sides of spring
Set 13,13 upper and lower ends of rubber sleeve are tightly connected with partition, filter core 8 respectively, 11 bullet of spring of the 8 top two sides of filter core
Property coefficient is different.
Multiple inner holes are provided on the partition 10, each inner hole is correspondingly arranged on a filter core 8, each filter
Core 8 is correspondingly arranged on a nozzle 1.
The pulsation gas source includes main pulse valve 3, auxiliary pulse valve 4, auxiliary gas bag 5, pulse control instrument 6, main gas bag 7, described

Instrument 6 processed controls.
Deashing to filter core 8 includes main pulse and auxiliary pulse, and a cycle of pulse is four subpulse deashings, is respectively:
Filtration velocity is 0.5~4.0m/min, then, altogether include four subpulse deashings when carrying out a wheel deashing:
1st auxiliary pulse jet, blowing time are 0.05s, dead time 0.10s, interrupt the air-flow of filtering wind and make
It is reversed, reduces the ventilation resistance of main jet blowing gas stream later, provides preferably blowing environment for main pulse.
2nd main pulse blowing, the blowing time is 0.15s, dead time 0.10s, in the base of the 1st auxiliary pulse jet
On plinth, surrounding flow is reversed when main jet blows starting, and two secondary volume of increase that can be blown is inhaled, and realizes bigger volume pipette, increases
The effect of strong deashing.
3rd auxiliary pulse jet, the blowing time is 0.05s, dead time 0.10s, in the work of auxiliary pulse jet pressure
Under, the distinguished and admirable resorption after main pulse is blown is postponed, the relatively fine dust on the surface for being suspended in filter core can be effectively prevented
The absorption again of particle improves the efficiency of deashing to strive for more sedimentation times from the dust that cartridge surface is removed.
The auxiliary pulse jet of the 4th, blowing time are 0.05s, dead time 60s, further remove and are possible to resorption
Fine dust particles.
After start to repeat above deashing, this is a cycle of pulse jet.
The jetting pressure of the auxiliary pulse is the 1/5~1/2 of main pulse.
During pulse dust cleaning, the coefficient of elasticity for being placed in the spring 11 of the left and right ends on filter core 8 is different, works as spray
When blow pressure power acts on filter core 8, the vibration of the generation of filter core 8 both vertically and horizontally can be made, and rubber 13 can prevent from leaking out
It is not influenced by dust with guarantee spring 11 and screw 12.
All in all in deashing process, the auxiliary pulse jet of first time has interrupted the air-flow of filtering wind, reduces main jet later
The ventilation resistance of blowing gas stream provides preferably blowing environment for main pulse.Second of blowing is main pulse jet, auxiliary for the first time
Air-flow on the basis of pulse jet around blowing is reversed, and two bigger secondary volume pipettes may be implemented, enhance the effect of deashing
Fruit.The jetting pressure that auxiliary pulse jet generates for the third time, it can postpone and filter distinguished and admirable recovery, can be effectively prevented and be suspended in
The absorption again of relatively fine dust particles around filter core.It is distinguished and admirable extensive that 4th auxiliary pulse jet further postpones filtering
It is multiple, inhibit the absorption again of dust around filter core, to strive for more sedimentation times from the dust that cartridge surface is removed.
In each pulse jet, jetting pressure can all act on filter core, to keep having for filter core left and right ends different
Deformation occurs for the spring of coefficient of elasticity, thus makes filter core that the vibration on both vertically and horizontally occur, and is effectively combined
The mode of mechanical ash removing exacerbates the removing of dust on filter element surface, enhances the effect of deashing.It is wrapped on spring and screw
Rubber can prevent from leaking out and guaranteeing that spring and screw are not influenced by dust.
