Hydraulic Pulper - Txheej txheem cej luam

Hydraulic pulper yog ib qho tseem ceeb ntawm cov khoom siv rau kev ua cov ntawv sau, tawg, thiab ntau hom ntawv pov tseg. Nws yog feem ntau muaj nyob rau hauv ob configurations: ntsug thiab kab rov tav. Lub hauv paus tsim revolves nyob ib ncig ntawm lub rotor thiab lub tub.

Nyob rau hauv cov qauv ntsug, lub rotor yog mounted centrally nyob rau hauv qab ntawm lub tub. Lub rotor disc yog nruab nrog ntau lub vanes (los yog cov hniav). Ib qho chaw ruaj khov disc nrog ntau cov hniav yog ntsia nyob ib ncig ntawm lub periphery ntawm lub rotor. Lub cev muaj zog tsav, feem ntau nyob hauv qab ncej, lub zog lub rotor. Ib qho perforated screen phaj yog ntsia rau ntawm tub hauv qab ze ntawm lub rotor.

Qhov kev tshuaj ntsuam no txuas mus rau lub qhov hluav taws xob, tso cai rau cov khoom sib cais.

Kab rov tav qauv muaj qhov sib txawv layout. Cov khoom tseem ceeb -rotor, daim hlau nyob ruaj ruaj, thiab lub vijtsam- yog tag nrho rau sab ntawm lub nkoj. Qhov no ua kom haum cov nroj tsuag sib txawv uas yuav tsum tau ua.

Thaum cov cuab yeej ua haujlwm, lub cev muaj zog tsav lub rotor ntawm kev kub ceev. Qhov no tsim lub zog centrifugal tseem ceeb. Cov nplooj ntawv pub mis thiab cov ntawv pov tseg raug pov tawm tsam cov hniav los ntawm lub zog no. Lawv muaj kev cuam tshuam. Tom qab ntawd cov khoom yog muab pov rau ntawm phab ntsa tub, ua ib tug kab rov tav vortex ntws raws periphery.

Cov khoom lag luam nce mus rau ntawm phab ntsa tub mus rau qhov siab. Tom qab ntawd nws poob rov qab mus rau thaj tsam rotor. Ib qho chaw siab tsis zoo ua rau hauv nruab nrab ntawm lub tub. Lub voj voog no rov ua tsis tu ncua. Nws tsim kom muaj zog ntsug vortex. Qhov kev txav mus los no ua rau cov khoom siv fiber ntau rov ua dua txhua yam cuam tshuam thiab kev sib txhuam.

Nyob rau tib lub sijhawm, cov khoom pov tseg tawm sab nraud ntawm lub rotor ntws mus rau qhov chaw. Nws linear tshaj tawm maj mam txo. Qhov no tsim ib qho kev tshaj tawm gradient. Qhov tshwm sim txheeb ze ua rau cov fibers rub tawm rau ib leeg. Qhov no ntxiv txhawb cov dispersion thiab sib cais ntawm fiber ntau bundles. Cov txheej txheem aims cais fibers tsis txiav lawv, khaws cia ntev fibers.

Qhov zoo ntawm cov cuab yeej no yog qhov tseem ceeb. Fiber sib cais yog maj mam. Nws tsuas yog nyob ntawm hydraulic shear thiab kev sib txhuam kom disperse fibers. Qhov no tsis txhob txiav cov fibers, uas muaj txiaj ntsig zoo rau lub zog ntawm cov pulp kawg. Ntau lawm efficiency yog kuj siab. Pulping lub sij hawm luv luv. Kev siv hluav taws xob tshwj xeeb yog qhov sib piv qis.

Cov qauv siv tshuab yog qhov yooj yim. Kev kho yog ncaj nraim. Cov cuab yeej siv thiab qhov xav tau hauv pem teb yog qhov me me. Kev ua haujlwm hloov pauv tau zoo. Nws tuaj yeem tswj tau ntau hom ntawv pov tseg thiab hom pulp. Nws yog qhov zoo - haum rau kev ua haujlwm tas mus li, tsis siv neeg ntau lawm.

Txawm li cas los xij, muaj qhov tsis txaus ntseeg meej. Cov khoom sib cais feem ntau muaj cov khoom me me, tsis muaj cov ntawv flakes. Qhov no cuam tshuam cov khoom sib xws thiab kev huv. Nws tuaj yeem cuam tshuam qhov zoo ntawm cov ntawv tom ntej.

Cov yam ntxwv ntawm raw khoom

Hom fiber ntau, dej absorbency, o muaj peev xwm, fiber ntau sib txuas lub zog, thiab seb cov khoom loj npaum li cas, luam tawm, thiab lwm yam, txhua yam cuam tshuam ncaj qha rau nws qhov ceev ceev thiab disintegration nyuaj hauv dej. Raws li cov txheej txheem zoo ib yam, cov khoom siv raw sib txawv yuav tsum muaj sijhawm sib txawv kom ua tiav tib theem ntawm fiber ntau sib cais.

Kev ua haujlwm sib xws

Kev khiav hauj lwm ntawm qhov sib xws ntau dua yog feem ntau tau txais txiaj ntsig, muab cov khoom lag luam zoo hauv lub tub yog khaws cia. Kev tshawb fawb qhia tau hais tias thaum tag nrho cov kev siv hluav taws xob nce nrog ntau dua qhov sib xws, lub zog siv ib chav tsev ntawm cov zis feem ntau txo qis. Qhov cuam tshuam ntawm qhov sib xws ntawm qhov kev sib cais zaum kawg thiab lub sijhawm pulping tsis tau hais ntau. Qhov tseem ceeb yog tswj cov dej dynamics zoo.

Lub Sijhawm Kho Mob

Pulping lub sij hawm yuav tsum tau tswj nyob rau hauv ib tug tsim nyog ntau yam. Raws li cov txheej txheem tshwj xeeb, muaj lub sijhawm sib cais fiber ntau zoo. Dhau lub qhov rais no, ncua lub sij hawm yields diminishing rov qab nyob rau hauv cov nqe lus ntawm kev sib cais degree. Los ntawm kev pom kev lag luam, qhov no tsis zoo. Yog li ntawd, lub sijhawm zoo yuav tsum tau txiav txim siab raws li cov khoom siv raw thiab lub hom phiaj zoo ntawm cov ntaub so ntswg, tsis txhob ua ntau tshaj -.

Kev Tswj Kub Kub

Kub yog qhov tseem ceeb ntawm cov txheej txheem. Ua kom kub softens pov tseg cov ntawv fibers. Nws accelerates dej nkag thiab fiber ntau o. Cov txiaj ntsig no tau tshaj tawm rau cov ntawv loj lossis cov ntawv luam tawm nrog tus cwj mem. Tsis tas li ntawd, qhov kub siab dua txo cov khoom viscosity. Qhov no txhim kho fluidity, yog li txhim kho fiber ntau ncig thiab sib cais efficiency.

Cov cuab yeej siv no yog siv dav hauv cov ntawv pov tseg pulping thiab cov ntawv pulp disintegration. Kev xaiv yuav tsum xav txog cov yam ntxwv ntawm cov khoom siv raw, kev tsim khoom, thiab cov kev xav tau rau kev ua haujlwm tas mus li lossis batch. Cov xwm txheej no txiav txim siab seb qhov ntsug lossis kab rov tav, siab - qhov sib xws lossis nruab nrab / qis- qauv sib xws yog tsim nyog.

Thaum lub sijhawm ua haujlwm tiag tiag, yuav tsum tau them nyiaj rau qhov sib piv ntawm lub vijtsam phaj lub qhov loj thiab qhov chaw qhib kom tsis txhob txhaws. Vane hnav yuav tsum tau tshuaj xyuas tsis tu ncua kom tswj tau cov pulping efficiency. Rau cov ntawv pov tseg uas muaj cov ntsiab lus tsis huv, nws feem ntau xav tau kev sib koom ua ke nrog siab - cov tshuaj ntxuav kom huv lossis cov theem tom ntej txhawm rau txhim kho cov khoom lag luam zoo.

Hauv cov ntsiab lus, hydraulic pulper yog qhov tseem ceeb ua ntej -chaw ua haujlwm hauv kab pulping. Nws qhov kev ua tau zoo yog cuam tshuam los ntawm ntau yam: tsim, kev ua haujlwm tsis zoo, thiab cov khoom siv raw. Kev xaiv kom raug thiab kev ua haujlwm zoo yog qhov tseem ceeb rau kev ua kom nws cov kev lag luam thiab kev ua haujlwm siab -.
