Hauv cov txheej txheem pulping ntawm kev lag luam ua ntawv, cov khoom siv raw (xws li cov ntoo chips thiab cov ntawv pov tseg) feem ntau muaj cov khoom tsis huv xws li xuab zeb, xuab zeb, hlau, thiab yas. Yog tias tsis tshem tawm raws sijhawm, cov khoom tsis huv no yuav ua rau cov khoom siv tom ntej hnav sai dua, cuam tshuam rau qhov zoo ntawm daim ntawv, thiab txawm tias ua rau muaj kev cuam tshuam ntau lawm. Raws li cov khoom siv ua ntej tseem ceeb, lub tshuab cais tawm slag muaj lub luag haujlwm tseem ceeb ntawmua tau zoo cais cov khoom hnyav thiab cov khoom tsis huv ntawm lub pulpNws muab cov pulp huv rau cov txheej txheem pulping tom ntej thiab ua haujlwm ua qhov txuas tseem ceeb kom ntseeg tau tias kev ua haujlwm ruaj khov ntawm cov kab ntau lawm ntawv.

I. Lub Hauv Paus Ua Haujlwm Tseem Ceeb: Tsav los ntawm ob qho tib si "Qhov Sib Txawv ntawm Qhov Ceev thiab Kev Sib Cais Mechanical"

Lub logic sib cais ntawm lub slag discharge separator yog raws li "qhov sib txawv ntawm qhov ceev ntawm cov khoom tsis huv thiab pulp" thiab ua tiav qhov kev tshem tawm cov khoom tsis huv los ntawm nws cov qauv kho tshuab. Cov txheej txheem kev siv tshuab tseem ceeb muaj ob kauj ruam:

1. Kev Sib Cais Hnyav ImpurityTom qab cov pulp nkag mus rau hauv lub tshuab pub khoom noj, nws xub ntws mus rau hauv "cheeb tsam sib cais cov khoom tsis huv hnyav". Hauv thaj chaw no, qhov ntws ntawm cov pulp qeeb qeeb. Cov khoom tsis huv hnyav xws li xuab zeb, xuab zeb, thiab cov hlau thaiv, uas muaj qhov ceev ntau dua li cov pulp, sai sai nkag mus rau hauv qab ntawm cov khoom siv vim yog lub ntiajteb txawj nqus. Tom qab ntawd lawv raug tso tawm tas li los ntawm lub qhov tso pa tawm slag tsis siv neeg lossis phau ntawv.
2. Kev Sib Cais Impurity Lub TeebCov pulp, uas cov khoom tsis huv hnyav tau raug tshem tawm, txuas ntxiv mus rau hauv "cheeb tsam sib cais cov khoom tsis huv me me". Thaj chaw no feem ntau muaj lub nruas lim uas tig tau lossis lub scraper. Cov khoom tsis huv me me xws li cov yas, cov fiber bundles, thiab cov hmoov av, uas muaj qhov ceev qis dua li cov pulp, raug cuam tshuam los ntawm lub nruas lim lossis khawb tawm los ntawm lub scraper. Thaum kawg, lawv raug sau los ntawm qhov hluav taws xob tsis huv me me, thaum cov pulp huv si mus rau cov txheej txheem tom ntej.

II. Cov Txheej Txheem Tseem Ceeb: Cov Cim Qhia Tseem Ceeb Uas Cuam Tshuam Rau Kev Ua Haujlwm Zoo Ntawm Kev Sib Cais

Thaum xaiv thiab siv lub tshuab cais cov slag, cov kev ntsuas hauv qab no yuav tsum tau tsom mus rau kom phim cov kev xav tau ntawm cov kab ntau lawm:

• Peev Xwm Ua Haujlwm: Qhov ntim ntawm cov pulp uas tuaj yeem ua tiav ib lub sijhawm (feem ntau ntsuas hauv m³ / h). Nws yuav tsum phim lub peev xwm tsim khoom ntawm cov khoom siv pulping pem hauv ntej kom tsis txhob muaj kev thauj khoom ntau dhau lossis pov tseg lub peev xwm tsim khoom.
• Kev Ua Haujlwm Sib Cais: Ib qho cim qhia tseem ceeb rau kev ntsuas qhov txiaj ntsig ntawm kev tshem tawm cov khoom tsis huv. Qhov ua tau zoo ntawm kev sib cais rau cov khoom tsis huv hnyav (xws li hlau thiab xuab zeb) feem ntau xav tau ≥98%, thiab rau cov khoom tsis huv me me (xws li yas thiab cov xov loj) ≥90%. Kev ua haujlwm tsis txaus yuav cuam tshuam ncaj qha rau qhov dawb thiab lub zog ntawm daim ntawv.
• Qhov qhib ntawm lub nruas npo: Txheeb xyuas qhov tseeb ntawm kev sib cais ntawm cov khoom tsis huv thiab raug kho raws li hom khoom siv raw (piv txwv li, qhov qhib ntawm 0.5-1.5 hli feem ntau siv rau kev ua cov ntawv pov tseg, thiab nws tuaj yeem ua kom loj dua rau kev ua cov ntoo pulp pulp). Qhov qhib me dhau yuav ua rau muaj kev thaiv, thaum qhov loj dhau yuav ua rau cov khoom tsis huv tawm.
• Kev Ua Haujlwm SiabLub zog ntws ntawm cov pulp hauv cov khoom siv (feem ntau yog 0.1-0.3MPa). Kev siab dhau heev tuaj yeem ua rau cov khoom siv puas tsuaj, thaum kev siab qis dhau cuam tshuam rau qhov ceev ntawm kev sib cais. Kev tswj hwm kom meej los ntawm lub qhov pub mis yog qhov tsim nyog.

III. Cov Hom Phiaj: Faib Los Ntawm Cov Qauv Thiab Daim Ntawv Thov

Raws li qhov sib txawv ntawm cov ntaub ntawv raw papermaking (ntoo pulp, ntawv pov tseg pulp) thiab hom impurity, slag discharge separators feem ntau yog muab faib ua ob pawg:

• Cov Khoom Sib Cais Hnyav Impurity (Desanders)Ua tib zoo saib xyuas kev tshem tawm cov khoom tsis huv. Lub tshuab "vertical desander" feem ntau muaj cov qauv me me thiab qhov chaw me me hauv pem teb, ua rau nws haum rau cov kab ntau lawm me me thiab nruab nrab; lub "horizontal desander" muaj peev xwm ua tiav loj dua thiab muaj peev xwm tiv thaiv kev txhaws, thiab feem ntau yog siv rau hauv cov kab ntau lawm pulping pov tseg loj.
• Cov Khoom Sib Cais Sib Txawv Sib Txawv (Slag Separators): Ua kom pom tseeb txog kev tshem tawm cov khoom tsis huv uas tsis muaj zog. Tus neeg sawv cev ib txwm muaj yog "lub tshuab cais cov slag uas siv lub tshuab lim siab", uas ua tiav kev sib cais los ntawm lub nruas lim uas tig thiab qhov sib txawv ntawm lub siab, thiab muaj ob qho tib si kev tshuaj ntsuam thiab kev tshem tawm slag. Nws yog siv dav hauv cov txheej txheem pulping ntawm cov khoom siv raw huv xws li ntoo pulp thiab xyoob pulp; kuj tseem muaj "centrifugal slag separator", uas siv lub zog centrifugal los cais cov khoom tsis huv uas tsis muaj zog thiab tsim nyog rau kev kho cov pulp uas muaj zog siab (kev sib xyaw ≥3%).

IV. Kev Txij Nkawm Txhua Hnub: Qhov Tseem Ceeb rau Kev Siv Khoom Siv Ntev thiab Ua Kom Zoo

Kev ua haujlwm ruaj khov ntawm lub tshuab cais cov slag tso tawm yog nyob ntawm kev saib xyuas tsis tu ncua. Cov ntsiab lus tseem ceeb ntawm kev saib xyuas suav nrog:

1. Kev Ntxuav Lub Nruas Screen Tsis Tu NcuaTom qab kaw txhua hnub, xyuas seb lub nruas ntawm lub vijtsam puas raug thaiv. Yog tias cov qhov apertures raug thaiv los ntawm cov fibers lossis cov khoom tsis huv, siv rab phom dej siab los yaug lossis siv cov cuab yeej tshwj xeeb los ntxuav lawv kom tsis txhob cuam tshuam rau kev sib cais ntawm kev ua haujlwm tom ntej.
2. Tshawb xyuas qhov sealing ntawm Slag Discharge ValvesKev xau ntawm cov qhov tso pa tawm hnyav thiab me me yuav ua rau cov pulp pov tseg thiab txo qhov cuam tshuam ntawm kev sib cais. Nws yog ib qho tsim nyog los xyuas seb lub rooj zaum valve puas hnav txhua lub lim tiam thiab hloov cov gaskets lossis cov qhov tso pa tawm puas lawm raws sijhawm.
3. Kev Siv Lubrication ntawm Cov Cheebtsam Tseem Ceeb: Ntxiv cov roj nplua nyeem tshwj xeeb rau cov khoom txav ntawm cov khoom siv, xws li lub qag tig thiab cov bearings, txhua hli kom tiv thaiv kev puas tsuaj ntawm cov khoom los ntawm kev sib txhuam qhuav thiab ua kom lub neej ua haujlwm ntev dua.
4. Kev Saib Xyuas Cov Kev Ua HaujlwmCov kev ntsuas saib xyuas lub sijhawm tiag tiag xws li lub peev xwm ua haujlwm, siab, thiab tam sim no los ntawm lub kaw lus tswj hwm. Yog tias cov kev ntsuas tsis zoo tshwm sim (xws li lub siab nce sai lossis tam sim no ntau dhau), nres lub tshuab tam sim ntawd rau kev tshuaj xyuas kom tsis txhob muaj kev puas tsuaj rau cov khoom siv vim muaj kev thauj khoom ntau dhau.

V. Cov Qauv Kev Txhim Kho Kev Lag Luam: Kev Txhim Kho Mus Rau "Kev Ua Haujlwm Zoo thiab Kev Txawj Ntse"

Nrog rau qhov xav tau ntxiv rau kev tiv thaiv ib puag ncig thiab kev ua haujlwm zoo hauv kev lag luam ntawv, cov tshuab cais tawm slag tab tom tsim kho hauv ob qho kev taw qhia tseem ceeb:

• Kev Ua Haujlwm ZooLos ntawm kev ua kom zoo dua qhov kev tsim cov kav dej ntws (piv txwv li, txais yuav "ob lub qauv hloov pauv ob cheeb tsam") thiab txhim kho cov khoom siv nruas lim (piv txwv li, cov hlau tsis xeb uas tsis yooj yim hnav thiab cov khoom sib xyaw ua ke siab), qhov kev ua haujlwm sib cais tau zoo dua ntxiv, thiab kev poob ntawm cov pulp tau txo qis (txo qhov kev poob ntawm 3% mus rau qis dua 1%).
• Kev txawj ntse: Siv cov sensors thiab PLC tswj system los ua ke kom ua tiav qhov kev sib koom ua ke ntawm "kev saib xyuas tsis siv neeg, kev hloov kho ntse, thiab kev ceeb toom ua ntej qhov txhaum". Piv txwv li, saib xyuas cov ntsiab lus tsis huv hauv lub pulp tiag tiag los ntawm lub sensor concentration impurity, thiab kho qhov siab pub thiab zaus tso tawm slag; yog tias cov khoom siv raug thaiv lossis cov khoom tsis ua haujlwm, lub system tuaj yeem ceeb toom tam sim ntawd thiab xa cov lus qhia txij nkawm, txo kev cuam tshuam tes thiab txhim kho qib automation ntawm cov kab ntau lawm.

Xaus lus, txawm hais tias lub tshuab cais cov slag tsis yog cov khoom siv "core" tshaj plaws hauv kab ntau lawm ntawv, nws yog "lub hauv paus" rau kev ua kom ruaj khov ntawm cov txheej txheem tom ntej thiab txhim kho cov ntawv zoo. Kev xaiv cov hom tsim nyog, kev tswj cov kev cai, thiab kev saib xyuas kom zoo tuaj yeem txo cov nqi tsim khoom, txo cov khoom siv tsis ua haujlwm, thiab muab kev txhawb nqa tseem ceeb rau kev tsim khoom zoo ntawm cov lag luam ua ntawv.
