Specific implementation process：
Cyclone bag-type combined dust collector operation principle：After dusty gas tangentially enters lower box 12, it is radial simultaneously by
To the effect of two kinds of power, first, centrifugal force caused by tangential velocity by dusty gas, makes dust be made by outside passage
With；The other is the centripetal force produced by radial velocity by dusty gas, makes dust by inside traction.If cut
The centrifugal force generated to speed is more than the centripetal force that radial velocity generates, then dust particles are outside under the promotion of centrifugal inertial force
Wall moves, and heavy dust particles hit 12 inner wall of lower box and are decelerated, and fall into ash bucket 123 under the effect of gravity, to realization pair
The first filtering of heavy dust particles in dusty gas；If tangential velocity generate centrifugal force be less than radial velocity generate to
Mental and physical efforts, then lightweight dust particles under the promotion of centripetal force enter inward eddy, through the cloth bag 2 in cyclone cylinder 121 to lightweight
Dust particles carry out secondary filter.
To the filter process of dusty gas：After dusty gas enters tangentially-arranged air inlet 122, outside cyclone cylinder 121
It rotates in circular passage between 12 inner wall of wall and lower box, the heavy dust particles in dusty gas are in centrifugal force
Effect is lower to hit 12 inner wall of lower box, falls into ash bucket 123 under the effect of gravity, realizes the first filtering of dusty gas；Ash-laden gas
Lightweight dust granulated in body carries out secondary filter, finally, clean gas through cloth bag 2 at inward eddy to dusty gas
It is discharged from gas outlet 111.
To the deashing process of cloth bag 2：Electromagnetic impulse valve 32 is opened by controller, and the compressed air in gas bag 31 enters injection
Pipe 33, by being blown 331 directive cloth bag 2 of mouth, compressed air passes through Venturi tube 212, and induction generates secondary gas flow, increases compression
Air is to the active force of cloth bag 2, and the dust of 2 outer wall of cloth bag is to shaking off.During pulse dust cleaning, compressed air enters cloth bag 2,
One downward pressure is generated to driving piece 2131, driving piece 2131 is bent downward, elastic metal sheet 213 is driven to be turned under
Folding, due to the return action of elastic metal sheet 213, makes elastic metal sheet 213 along far from cloth bag frame 21 after deashing process
The direction of axis moves, at this point, elastic metal sheet 213 generates beating effect to cloth bag 2, final dusting is carried out to cloth bag 2.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can as needed make the present embodiment the modification of not creative contribution after reading this specification, but
As long as all being protected by Patent Law in the right of the utility model.
