Cov khoom siv raw ua tiav los ntawm hydraulic pulper tseem muaj cov ntawv me me uas tsis tau xoob tag, yog li nws yuav tsum tau ua tiav ntxiv.Kev ua tiav ntawm fiber ntau yog qhov tseem ceeb heev los txhim kho qhov zoo ntawm cov ntaub ntawv pov tseg.Feem ntau hais lus, pulp disintegration tuaj yeem ua tiav hauv cov txheej txheem tawg thiab ua kom zoo dua.Txawm li cas los xij, cov ntaub ntawv pov tseg twb tau tawg lawm, yog tias nws tau xoob dua nyob rau hauv cov khoom siv tawg, nws yuav siv hluav taws xob siab, kev siv cov khoom siv yuav tsawg heev thiab lub zog ntawm cov pulp yog txo los ntawm fiber ntau. txiav dua.Yog li ntawd, kev sib cais ntawm cov ntawv pov tseg yuav tsum tau ua kom zoo dua yam tsis muaj kev txiav cov fibers, fiber ntau cais yog los ntawm tam sim no cov cuab yeej siv dav tshaj plaws rau cov ntawv pov tseg ntxiv.Raws li cov qauv thiab kev ua haujlwm ntawm fiber ntau separator, fiber ntau separator tuaj yeem muab faib ua ib qho txiaj ntsig fiber ntau cais thiab ntau cov fiber ntau cais, feem ntau siv yog tib cov nyhuv fiber ntau cais.
Cov qauv ntawm ib qho nyhuv fiber ntau cais yog yooj yim heev.Txoj kev xav ua haujlwm yog raws li hauv qab no: cov slurry ntws los ntawm sab saum toj me me txoj kab uas hla ntawm lub khob hliav qab lub plhaub thiab tso rau ntawm tangential kev taw qhia, lub impeller rotation kuj muab cov twj siv zog uas tso cai rau cov slurry tsim axial ncig thiab tsim muaj zog sib sib zog nqus tam sim no, cov fiber ntau. yog relieved thiab loosened nyob rau hauv qhov sib txawv ntawm lub impeller ntug thiab hauv qab ntug.Lub sab nraud ntawm lub impeller yog nruab nrog ib tug ruaj sib cais hniav, uas tsis tsuas yog txhawb fiber kev sib cais tab sis kuj generates turbulent flow thiab scours screen phaj.Cov slurry zoo yuav raug xa los ntawm lub vijtsam tuav rau sab nraub qaum ntawm lub impeller, lub teeb impurities xws li yas yuav yog qhov chaw nruab nrab ntawm lub hau npog thiab tso tawm tsis tu ncua, qhov hnyav impurities cuam tshuam los ntawm lub zog centrifugal, ua raws li cov kab ntawm kauv nyob rau sab hauv. phab ntsa rau hauv qhov chaw nres nkoj sediment hauv qab ntawm txoj kab uas hla loj kawg kom tso tawm.Kev tshem tawm ntawm lub teeb impurities nyob rau hauv lub fiber separator yog nqa tawm intermittently.Lub sijhawm qhib ntawm qhov tso tawm valve yuav tsum ua raws li tus nqi ntawm lub teeb impurities hauv cov ntaub ntawv pov tseg.Ib qho txiaj ntsig fiber ntau cais yuav tsum xyuas kom cov fiber ntau yog xoob tag nrho thiab lub teeb tsis huv yuav tsis tawg thiab sib xyaw nrog cov tawv nqaij zoo.Tsis tas li, cov txheej txheem yuav tsum tsis tu ncua cais cov yeeb yaj kiab yas thiab lwm yam teeb pom kev tsis zoo kom tso tawm hauv lub sijhawm luv los xyuas kom meej thiab kho qhov sib npaug ntawm cov fiber ntau cais, feem ntau, lub teeb impurities tawm valve tau tswj kom tso tawm ib zaug txhua 10 ~ 40s, 2 ~ 5s txhua lub sijhawm. Nws yog qhov tsim nyog, qhov hnyav impurities raug tso tawm txhua 2 teev thiab thaum kawg ua tiav lub hom phiaj ntawm kev sib cais thiab tu cov ntaub so ntswg.
