Nyob rau hauv cov ntaub ntawv pov tseg ntawm kev lag luam papermaking, fiber ntau cais yog cov cuab yeej tseem ceeb kom paub txog kev defibering ntawm cov ntawv pov tseg thiab xyuas kom cov ntaub ntawv zoo. Lub pulp kho los ntawm hydraulic pulper tseem muaj undispersed cov ntawv me me. Yog hais tias cov cuab yeej siv sib tsoo yog siv los kho cov ntaub ntawv pov tseg, tsis yog tsuas yog lub zog siv hluav taws xob siab thiab cov cuab yeej siv tau qis, tab sis kuj yog lub zog ntawm cov pulp yuav txo qis vim qhov rov txiav cov fibers. Cov fiber ntau cais tawm tuaj yeem tawg cov fibers tag nrho yam tsis tau txiav lawv, thiab tau dhau los ua cov ntaub ntawv pov tseg siv dav siv tam sim no.

Kev faib tawm ntawm Fiber Separator

Raws li qhov sib txawv ntawm cov qauv thiab kev ua haujlwm, fiber ntau separators feem ntau muab faib ua ob hom:Ib qho cuam tshuam fiber ntau separatorsthiabfiber ntau separators.

Tib-effect Fiber Separator: Ingenious Structure, Clear Function

Ib qho kev cuam tshuam fiber ntau cais muaj qhov tsim qauv tsim nyog (raws li qhia hauv daim duab ua haujlwm ntawm daim duab 5-17). Nws txoj haujlwm ua haujlwm yog raws li nram no: lub pulp yog pumped mus rau hauv me me-inch kawg ntawm lub conical plhaub los ntawm saum toj no raws li tangential kev taw qhia. Thaum lub impeller tig, cov hniav kuj muaj cov twj tso kua mis, ua rau lub pulp tsim axial ncig thiab muaj zog turbulent ncig. Nyob rau hauv qhov sib txawv ntawm lub impeller ntug thiab hauv qab riam, thiab nruab nrab ntawm lub impeller thiab lub vijtsam phaj, lub pulp yog defibered thiab sib cais ua fibers.

• Zoo Pulp Sib cais: Cov kev sib cais hauv qab riam ruaj ruaj ntawm qhov chaw ntawm lub impeller tsis tsuas yog txhawb nqa kev sib cais fiber ntau, tab sis kuj tseem ua rau muaj kev kub ntxhov rau scour qhov screen qhov, thiab cov pulp zoo yog thaum kawg xa tawm ntawm qhov screen qhov nyob rau sab nraum qab ntawm lub impeller.
• Kev tshem tawm impurity: Lub teeb impurities xws li yas zaj duab xis yog concentrated nyob rau hauv lub axis vim lub eddy tam sim no cov nyhuv, thiab yog tawm tsis tu ncua los ntawm lub hauv paus qhov hluav taws xob ntawm lub pem hauv ntej cover ua ke nrog ib tug me me ntawm cov ntaub ntawv sib xyaw; hnyav impurities yog raug rau centrifugal quab yuam thiab nkag mus rau hauv lub slag tawm chaw nres nkoj hauv qab qhov loj-inch kawg raws phab ntsa sab hauv kauv kab yuav tsum tau tawm.

Nyob rau hauv cov nqe lus ntawm kev lag luam tswj, lub sij hawm qhib ntawm lub teeb impurity tawm valve yuav tsum tau kho raws li cov ntsiab lus ntawm lub teeb impurities nyob rau hauv cov ntaub ntawv pov tseg fiber ntau raw khoom. Feem ntau, kev tswj tsis siv neeg tso tawm ib zaug txhua 10-40s, txhua zaus rau 2-5s; hnyav impurities raug tso tawm ib zaug txhua 2 teev. Los ntawm kev tswj xyuas kom meej, nws tuaj yeem cais cov fibers tag nrho thaum tsis txhob rhuav tshem lub teeb pom kev zoo xws li cov yas, thiab rov qab sib cais sai, thaum kawg paub txog kev sib cais thiab kev huv ntawm fibers.

Nrog nws cov qauv tsim tshwj xeeb thiab kev ua haujlwm mechanism, fiber ntau cais qhia qhov zoo ntawm cov ntawv pov tseg defibering txheej txheem. Nws tsis tsuas yog daws qhov tsis zoo ntawm cov khoom siv sib tsoo, tab sis kuj ua tiav cov dej num ntawm fiber ntau dispersion thiab impurity sib cais, tso lub hauv paus ruaj khov rau kev txhim kho qhov zoo ntawm cov ntaub ntawv pov tseg thiab ua kom cov ntaub ntawv ntau lawm. Nws yog ib qho tseem ceeb ntawm cov khoom siv tseem ceeb hauv cov ntaub ntawv pov tseg ntawm kev lag luam niaj hnub papermaking.
