Lub planifter yog lub hauv paus, lub plawv ntawm kev sib tsoo seem nyob rau hauv ib tug niaj hnub hmoov zeb. Yog hais tias lub mills yog "tus kws tshaj lij," ces cov kev npaj yog "tus tswv ntawm kev sib cais qhov tseeb." Nws daim ntawv thov theem ncaj qha txiav txim siab cov hmoov nplej rho tawm, tawm los, khoom zoo, thiab kev ruaj ntseg ntawm tag nrho cov zeb.
I. Cov hauj lwm tseem ceeb: Sifting thiab muab qhab nia
Lub luag haujlwm tseem ceeb ntawm cov phiaj xwm yog kom tsis tu ncua, ua tau zoo, thiab raug sift thiab qib cov khoom sib xyaw los ntawm cov menyuam mills, uas muaj cov khoom sib txawv xws li hmoov nplej, bran, thiab endosperm.
Extracting tiav hmoov nplej:Sib cais cov khoom zoo tshaj plaws uas ua tau raws li cov ntsiab lus ntawm cov hmoov nplej los ntawm kev sib xyaw kom raug xa mus rau cov khoom tiav mus rau theem tom ntej.
Qib Intermediate Stocks:Kev faib cov khoom loj dua uas tseem tsis tau zoo txaus rau hauv qib sib txawv raws li qhov loj thiab qhov zoo (xws li cov ntsiab lus bran). Cov qib no suav nrog cov hmoov nplej ntxhib (dunst), semolina, middlings, thiab bran.
Tsim kom muaj txheej txheem Flow:Precisely conveying txhua graded Tshuag rau nws lub tshuab tom ntej no nyob rau hauv tus txheej txheem (xws li txawv cov menyuam mills los yog purifiers), yog li tsim lub circulatory network ntawm tag nrho cov milling system.
II. Txoj hauj lwm thiab lub luag hauj lwm nyob rau hauv cov hmoov zeb Flow Sheet
Plansifter tsis ua haujlwm nyob rau hauv kev sib cais. Nws yog khub nrog cov menyuam mills los ua "sib tsoo-sifting" units. Tag nrho cov txheej txheem milling yog tsim los ntawm kev sib txuas ntau yam xws li hauv cov koob.
Txheej txheem Cycle:
Roller Mill (Tsib Sib Tsoo) → Plansifter (Sifting & Grading) → Graded Stocks → Respectively xa mus rau tom ntej no cov Roller Mill los yog Purifier → Reground → Nkag mus rau tom ntej Plansifter ...
Lub voj voog no rov ua dua, nce qib ntawm cov endosperm los ntawm bran thiab txo nws mus rau hmoov.
Qhov System Layout:Hauv 100-tuj / hnub hmoov nplej, ntau cov phiaj xwm feem ntau yog siv, txhua lub luag haujlwm rau sifting cov dej num nyob rau hauv txawv "systems," piv txwv li:
Break System Plansifter:Kov cov khoom los ntawm kev tawg yob. Nws lub luag haujlwm tseem ceeb yog rho tawm ntau qhov siab ntawm - cov hmoov nplej zoo thiab cov qhab nia zoo, cov khoom nruab nrab ntxhib, thiab cov khoom zoo.
Reduction System Plansifter:Kov cov khoom los ntawm kev txo cov yob. Nws txoj hauj lwm yog kev sib tsoo zoo thiab sifting ntawm cov ntshiab endosperm hais los tsim high-qib, qis- hmoov tshauv.
Scratch System Plansifter:Kov cov khoom los ntawm khawb rolls. Nws ua cov khoom endosperm nrog me me bran txuas rau kev ua kom huv ntxiv.
Tailings System Plansifter:Kov cov khoom los ntawm tailings rolls. Nws ua cov khoom lag luam nrog cov ntsiab lus ntau dua bran, aiming kom rho tawm cov hmoov nplej kom ntau li ntau tau thaum tswj cov hmoov nplej zoo.
III. Txoj Cai Ua Haujlwm thiab Cov Txheej Txheem Ua Haujlwm
Core Structure:
Sieve Casing:Lub tsev steel siab, sab hauv muab faib ua ob peb qhov chaw ywj pheej lossis "seem."
Sieve Frames:Cov khoom tseem ceeb ua haujlwm. Txhua pawg ntawm cov thav ntawv muaj cov sieves nrog cov lus qhia sib txawv (woven los ntawm silk los yog nylon mesh). Lub mesh aperture feem ntau ua finer los ntawm sab saum toj mus rau hauv qab, los yog configured raws li cov txheej txheem yuav tsum tau. Cov khoom txav nyob rau hauv kab rov tav rotary motion nyob rau hauv lub thav duab. Cov khoom me dua li qhov aperture hla dhau ("dhau"), thaum cov khoom loj dua nyob rau ntawm lub sieve nto ("overtails").
Tsav Mechanism:Feem ntau yog tsav los ntawm lub tshuab ntsug ntsug mounted rau saum. Nws generates kab rov tav, dav hlau teb motion los ntawm counterweights. Cov lus tsa suab no sib npaug sib npaug ntawm cov khoom siv thoob plaws lub sieve nto, ua rau nws txav mus rau sab nraud kom muaj kev sib cuag nrog lub apertures.
Txheej txheem ua haujlwm:
Pub:Cov khoom siv hauv av nkag los ntawm sab saum toj ntawm cov phiaj xwm thiab muab faib rau hauv cov khoom sib txawv thiab cov kev khiav dej num ua ntej.
Progressive Sifting:Cov khoom siv, uas tau tsav los ntawm cov lus tsa suab, dhau los ntawm ntau lub sieve txheej nrog ntau qhov sib txawv mesh.
Qib & Collection:Txhua txheej sieve cais cov khoom mus rau hauv overtails (tso tseg) thiab dhau (dhau). Cov ntaub ntawv los ntawm cov txheej txheem sib txawv thiab cov txheej txheem ntws tau sib cais los ntawm cov channel sab hauv.
Tshem tawm:Thaum kawg, ntau qhov chaw nyob hauv qab ntawm cov phiaj xwm ib txhij tso tawm ntau yam khoom lag luam. Cov no yog tom qab ntawd raug xa mus (feem ntau pneumatically) rau lawv qhov chaw nyob.
IV. Ntsiab Technical Parameters thiab Impact
Qhov kev ua tau zoo ntawm cov phiaj xwm hais txog kev ua haujlwm ntawm tag nrho cov txheej txheem milling:
Sifting Surface Area:Qhov loj sifting cheeb tsam txhais tau tias muaj peev xwm ntau dua thiab ntau dua sifting. Plansifter lub ntsiab kom zoo dua yog ua kom tiav ib tug loj sifting cheeb tsam nyob rau hauv ib tug me me hneev taw los ntawm stacking ntau txheej. Ib 100-tuj / hnub zeb xav tau txaus sifting cheeb tsam configured raws li nws cov txheej txheem tsim.
Sieve Configuration:Kev xaiv ntawm sieve specifications (mesh suav, khoom siv, weave ntom) yog ib qho tseem ceeb ntawm cov txheej txheem tsim. Nws ncaj qha txiav txim siab grading precision, qhov sib piv ntawm cov khoom sib txawv, thiab cov hmoov nplej zaum kawg (xws li particle loj, cov ntsiab lus tshauv).
Sifting Efficiency:Qhov feem pua ntawm cov hmoov sib cais uas tau muab rho tawm los ntawm cov Tshuag. Kev ua haujlwm siab ua kom "qhov siab tshaj plaws rho tawm," txo qis cov khoom siv rov ua dua tshiab, nce cov hmoov nplej thiab muaj peev xwm, thiab txo qis zog noj.
Motion Parameters:Kev sib hloov ceev thiab eccentricity txiav txim siab ceev thiab trajectory ntawm cov khoom ntawm lub sieve nto. Cov no xav tau kev ua kom zoo raws li cov yam ntxwv ntawm cov khoom lag luam thiab cov khoom siv sieve.
Sieve Ntxuav:Txhawm rau tiv thaiv qhov muag tsis pom (clogging), sieve thav duab feem ntau muaj cov khoom siv tu (piv txwv li, canvas strips, rubber balls) uas thaws tawm tsam hauv qab ntawm lub mesh thaum lub sijhawm ua haujlwm, ua kom lub apertures meej.
V. Summary: Lub "Separation Hub" ntawm txoj kev Milling
Lub luag haujlwm ntawm cov phiaj xwm tuaj yeem nkag siab los ntawm kev sib piv:
Traffic Control Center:Nws yuav siv sij hawm sib xyaw "tsheb" (cov khoom siv hauv av los ntawm cov menyuam mills) thiab qhia meej txhua lub tsheb (particle) mus rau nws qhov tseeb tom ntej qhov chaw raws li nws "hom thiab qhov chaw" (qhov loj thiab qhov zoo).
Quality Gatekeeper:Los ntawm kev muab qhab nia zoo, nws ua kom ntseeg tau tias tsuas yog cov endosperm ntshiab nkag mus rau hauv qhov txo qis, ua rau muaj kev tsim cov khoom zoo ntawm - cov hmoov nplej tshwj xeeb. Nws kuj tseem tiv thaiv cov bran ntau dhau los ntawm kev kis cov hmoov nplej, ua kom cov hmoov nplej purity.
Guarantor ntawm Yield thiab Profitability:Lub peev xwm sifting ntawm lub planifter feem ntau yog qhov tseem ceeb hauv lub tshuab zeb ntau lawm. Nws ua haujlwm tau zoo thiab ruaj khov yog qhov tseem ceeb rau kev ua tiav cov nroj tsuag tsim lub peev xwm thiab rho tawm tus nqi.
Yog tsis muaj cov phiaj xwm, qhov ua tau zoo, meej, thiab txuas ntxiv ntawm cov hmoov nplej niaj hnub yuav ua tsis tau. Nws nyob ntsiag to nyob rau hauv lub zeb, ua tiav complex thiab meej "sorting commands" los ntawm nws phav phav ntawm internal mesh apertures, sawv cev rau ib tug ntawm cov feem ntau technologically tseem ceeb core Cheebtsam nyob rau hauv txoj kev los ntawm "sib tsoo" mus rau "tiav hmoov."
