1.4SafetyRegulations
1.4.1TheAttentionsforUsing the Blower
1)Theblowercoverwill be heatedupduringoperation.Keephandsawayhigh
temperatureblowercovertoavoidhandsburning.
2)Motorunderload current will be varied withair pressureofthe blower.
Overload relayshouldbe used andkeepmotorworkingcurrent within
full-load current toavoidmotorburningout.
3)Air filterisused tokeep offdirts,particles, fibres, and waterdrops. Clean the
filteraboutonceaweek.
4)Clearupinsideandoutsideof theblowerregularly. If therearetoomuchdirts
accumulated on the blower, the function oftheblowerwillbe affected, such
astemperaturerising, reducedair volumeandhighernoiseleveldueto
vibration.All the abovefactorsareliabletocausemechanicalproblems.
5)Thebearing, sealringand silencerareall consumableparts.Theyshouldbe
replacedafteraperiod oftime.And alsothe fans, covers, and metalgrids
needtobechanged when necessary.
6)Ifthe blowercan notworkproperlyormakesloud noises,pleaseturnoff the
powersupplytohaveacheck.

2.1WorkingPrinciple
Drying: based on the principleofwaterhightemperaturegasification,moisture
ofmaterialwouldbe blownawaybyhighpressureair fromblowerafterbeing
hightemperaturegasified.Apartofair withmoisturedischargesthroughfilterof
moistureoutlet; mostpartofair arerecyclableafterbeingfilteredthroughreturn
air pipe.
Conveying: suction forceofhighpressureblowermakesavacuuminside
hopperalsoproducesdifferentialpressurebetween hopperandouterspace.
Withthe common forceofdifferentialpressureandcontinuoussuction,
materialsandair mixturewillbe suckedintohopper. Due tothe filterblock of
hopper,materialswill beaccumulatedinhopperandtheair isexpelled fromair
outlet. Double-stageconveyingismainlyaccomplished byshiftingthree way
