Abstract
A bag-type duster with pulse positioning, rotary back-blowing function is composed of cyclone dusting system, filter dusting system, rotary arm in ash cleaner, step-type drive mechanism, and the ratio of K = t between start and stop timeMovable part/tStop<When the rotary arm stays at the position of the mouth of the filter bag, a pulse valve arranged between the back-blowing fan and the rotary arm is opened at least twice, so that positioning pulse back-blowing airflow is formed for cleaning ash, compared with the existing non-positioning and pulse-free ash cleaning mode, the novel bag type dust collector has the obvious advantages of good ash cleaning effect, high dust cleaning efficiency and prolonged service life of the filter bag, and is suitable for effectively treating and recycling industrial dust.
Description
The utility model relates to a kind of sack cleaner, particularly cyclone dust removal is combined with dust removal by filtration, and has the novel sack cleaner of location pulsating deashing mechanism.
Sack cleaner is widely used in the processing of industrial dust and recovery, to reduce environmental pollution.The rotary counter-blowing sack cleaner that generally adopts has cyclone system and dust removal by filtration system at present, by cyclone body big dust particle is separated falling into ash bucket earlier, through filter bag the granule dust is filtered detention again.Along with the carrying out of filtering operating mode, the attached suction in the dust of filter bag outer surface constantly thickens, and needs regularly deashing.Existing deashing device is by back blowing machine, by turning arm clean gas flow is sent in the filter bag one by one, and dust layer is carried out blowback, and turning arm is driven by reduction gearing mechanism.Its shortcoming is that reduction gearing mechanism is gear drive and worm and gear transmission, and turning arm can only be done continuous uniform rotation, and is shorter relatively in the time that each sack stops, thereby the effective time of deashing is few, and deashing is not thorough; The wind of blowback is simultaneously supplied with continuously, the dead-beat process, and ash-removal effect is bad, and then reduces efficiency of dust collection, shortens life of bag filter.
The purpose of this utility model is to overcome weak point of the prior art, provides a kind of ash-removal effect good, can improve the location pulsation rotary counter-blowing sack cleaner of efficiency of dust collection, prolongation life of bag filter.
The technical solution of the utility model is: location pulsation rotary counter-blowing sack cleaner mainly comprises the cyclone system that is made of spiral case, by dust removal by filtration system and main air blower that filter bag and deashing device constitute, and wherein deashing device is made of turning arm, reductor, transmission mechanism and back blowing machine.Improvements are that described transmission mechanism is a stepping transmission mechanism, owe-tooth gear in this mechanism links to each other with speed reducer output shaft, owe-tooth gear only has tooth in 1/4～1/3 circumference, in all the other circumference is circular arc, link to each other with worm shaft with the full-depth tooth gear that owe-tooth gear matches, worm-wheel shaft links to each other with turning arm.Turning arm is, stops two states alternately, moves, stops time ratio K=t
Moving/ t
Stop＜1, position and filter bag opening position when turning arm stops match.Be provided with pulse valve between back blowing machine outlet and the import of turning arm air channel, the spool of this pulse valve links to each other with transmission mechanism in the deashing device.Pulse valve is opened twice when turning arm stops at least.Turning arm is longer in the time that sack stops like this, and the time of moving between sack is shorter; When turning arm stopped at sack, the blowback air-flow formed pulsed.
Above-mentioned pulse valve is rotary or the slidingtype mechanical valve, and its spool links to each other with transmission mechanism by chain sprocket, makes the action of pulse valve spool and turning arm stop state adapt dependable performance.
The air inlet of back blowing machine links to each other with the outlet of main air blower or clean room, and the clean gas after the introducing dedusting is avoided causing the damage of filter bag because of the temperature difference produces the dewfall phenomenon as the blowback air-flow.
Adopt technique scheme, the utility model carries out deashing when turning arm stops, and the time of staying is longer relatively, and the blowback air-flow becomes pulsed, forms oscillatory process, does not produce the dewfall phenomenon again, thereby ash-removal effect is good, and the efficiency of dust collection height can prolong life of bag filter.
Further specify the utility model embodiment below in conjunction with accompanying drawing.
Fig. 1 is the utility model overall structure schematic diagram;
Fig. 2 is a location pulsing mechanism schematic diagram in the deashing device.
Present embodiment partly is made up of cyclone system, dust removal by filtration system and main air blower, ash bucket etc.Under the main air blower swabbing action, dusty gas enters spiral case cyclone body 6 by the arrow place, and big dust particle separates earlier and falls into ash bucket, and the molecule dust enters the filter chamber with air-flow, through hanging the detention of the filter bag 5 on card 4, purifying gas flow is discharged from arrow.When filter bag outer surface dust layer reaches certain thickness, self-con-tained unit sends signal, and deashing device 1 is started working.Owe-tooth gear 9 links to each other with reductor 7, and full-depth tooth gear 10 is done stepping by worm and worm gear driven rotary arm 3 and rotated, and owe-tooth gear only has tooth in 1/3 circumference.The design of worm and worm gear and the distribution of filter bag adapt, and just in time match with the position of filter pocket mouths when turning arm is stopped at every turn.Hollow shaft 12 rotates with worm gear, and its below links to each other with turning arm 3.The blowing mouth 11 and the pulse valve between the hollow shaft 12 8 that are arranged on back blowing machine 2 are double leaf rotary machine valve, and this valve turning cylinder links to each other with reducing gear by chain sprocket, opens twice when turning arm stops, and form pulsation blowback air-flow.The air inlet of back blowing machine links to each other with the air outlet of main air blower.
Claims (3)
1, a kind of location pulsation rotary counter-blowing sack cleaner, comprise the cyclone system that constitutes by spiral case, the dust removal by filtration system and the main air blower that constitute by filter bag and deashing device, wherein deashing device is by turning arm, reductor, transmission mechanism and back blowing machine constitute, it is characterized in that described transmission mechanism is a stepping transmission mechanism, owe-tooth gear in this mechanism links to each other with speed reducer output shaft, owe-tooth gear only has tooth in 1/4～1/3 circumference, in all the other circumference is circular arc, link to each other with worm shaft with the full-depth tooth gear that owe-tooth gear matches, worm-wheel shaft links to each other with turning arm, and position and filter bag opening position when turning arm stops match; Be provided with pulse valve between back blowing machine outlet and the import of turning arm air channel, the spool of this pulse valve links to each other with transmission mechanism in the deashing device, and pulse valve is opened twice when turning arm stops at least.
