Description
Technical field
The utility model relates to the auxiliary equipment technical field of the production of tobacco, particularly relates to cleaner, is specially a kind of deashing device for deduster.
Background technology
For guaranteeing the cleannes of cigarette factory building, all dispose the deduster for environmental dust removal in the factory building, because the deduster live load is heavier, and the length of service that has is longer, the surface of filter cylinder produces a large amount of dust stratifications in the deduster, when serious in addition occur putting up a bridge, situation that ash is stifled, blower fan is made wind by this filter cylinder the time, be subjected to very big resistance, cause blast sharply to descend, the service point air quantity is die-offed, cause deduster can not satisfy deduster normally, effectively the operation, cause deduster can not satisfy the needs of production technology.
General deduster mainly by casing, advance/exhaust duct, ash bucket, dust remover, five parts of filter cylinder form, its operation principle is: filter cartridge dust remover is the negative pressure of utilizing blower fan to produce, the flue dust suction of service point is come, send effect with environmental dust removal or the wind of realizing service point.When dust-contained airflow arrives deduster, be introduced into expansion chamber, because air velocity changes, soot dust granule bigger in the air-flow falls into ash bucket under the effect of deadweight.Air-flow passes filter cylinder subsequently, and most of dust is blocked on the filter cylinder outer surface, and clean gas flow enters filter core, is disposed to atmosphere by connecting pipe.Deduster is judged the gas permeability of filter cylinder, when gas-flow resistance reaches setting value according to monitoring filter cylinder external and internal pressure difference, the action of pulse control instrument control magnetic valve, send paroxysmal compressed air to cartridge interior, air-flow is by purging outside filter cylinder in the filter cylinder, in order to shake off the laying dust of filter cylinder outer surface.
But because a lot of deduster filter cylinder is arranged closely, spacing is less, after dust drops, pile up between filter cylinder easily, the used filter cylinder of the deduster that has is papery gauffer formula, and filter area is bigger, cost is relatively low, stops up filter element but molecule takes place easily, and the problem of easy to clean not.
Contained flue dust contains tar, sugar and moisture in the air-flow of deduster processing simultaneously, and particle is tiny, easier obstruction filter cylinder, in addition, because flue dust contains tar, sugar and moisture, cause the filter cylinder superficial dust too real, can't thoroughly remove the filter cylinder superficial dust, cause dust stratification more and more thicker.
Because ash is stifled, air quantity descends, and according to the maintaining requirement of deduster, can be considered normal operating conditions at equipment magnetic differential pressure indicator reading at 1～6 o'clock, reaches more than 6, should safeguard; Reach 8 when above, just must change filter cylinder, guaranteeing the deduster operational effect, thereby increased Material Cost, human cost; Owing to the filter cylinder superficial dust, when opening deduster taking-up filter cylinder, have volume of smoke and fly up in addition, and when the appearance bridging, when ash blocks up phenomenon, also need impact or strike the grey piece that looses, the situation of flying dust is even more serious, causes the pollution of dedusting room environment and to the threat of staff's health.
