Author: Smartweigh-Multihead Weighter

Multihead weighter (Loss-in-weightfeeder) yog ib qho kev soj ntsuam ntau ntawm cov khoom hnyav uas muab cov khoom siv, feem ntau yog siv, multihead weighter yog siv rau dynamic nruam net hnyav nyob rau hauv tag nrho cov txheej txheem, muaj peev xwm nqa tawm net hnyav thiab quantitative tsom xam ntawm raw cov ntaub ntawv uas yuav tsum tau. tsis tu ncua muab, thiab tso saib cov ntaub ntawv hais txog cov khoom siv raw. Instantaneous tag nrho ntws thiab tag nrho cov dej ntws. Lub hauv paus ntsiab lus tseem ceeb yog cov ntaub ntawv zoo li qub net hnyav tshuab thiab cov cuab yeej siv, cov cuab yeej nqa hnyav ntawm cov ntaub ntawv static warehouse scale raug xaiv, thiab lub load cell net hnyav warehouse yog siv. Txawm li cas los xij, nyob rau hauv kev tswj vaj huam sib luag ntawm multihead weighter, thiaj li yuav zoo dua kom tau txais qhov hnyav poob hauv ib chav tsev lub sij hawm ntawm cov khoom siv raw khoom, nws yog ib qho tsim nyog los ntsuas qhov tam sim no tag nrho cov khoom siv raw.

Sab laug ntawm daim duab 1 yog daim duab duab ntawm qhov ntsuas qhov hnyav uas ploj lawm. Thaum cov khoom siv raw hauv lub net hnyav warehouse tsis muaj cov khoom tsim nyog, cov khoom siv raw tuaj yeem qhib. Thaum lub siab tshaj plaws raw khoom txoj hauj lwm yog mus txog, raw khoom valve kaw, thiab lub net hnyav warehouse tau txais kev txhawb los ntawm lub net hnyav uas ploj lawm scale. Point. Txhawm rau ua kom qhov hnyav dua qhov tseeb, sab sauv thiab sab qis ntawm lub khw muag khoom hnyav yog txuas nrog raws li cov lus muag muag thiab kev nkag thiab tawm, thiab pem hauv ntej thiab nram qab, sab laug thiab sab xis cov cuab yeej thiab cov khoom siv thiab cov khoom hnyav ntawm cov khoom siv raw hauv. nws tsis ntxiv rau lub tsev rau khoom hnyav. Sab xis ntawm daim duab 1 yog qhov kev npaj saib ntawm tag nrho cov txheej txheem ntawm kev muab khoom tas mus li. Muaj ib lub voj voog kaw lus rau tag nrho cov txheej txheem ntawm kev xa khoom tas mus li (cov ntaub ntawv ntawm daim duab qhia txog 3 lub voj voog).

Txhua lub voj voog muaj 2 lub sij hawm: thaum lub net hnyav warehouse yuav txo tau lub warehouse, net hnyav ntawm raw cov ntaub ntawv nyob rau hauv lub net hnyav warehouse yog nce, thiab thaum lub siab tshaj plaws raw khoom txoj hauj lwm yog mus txog ntawm t1, raw khoom. valve raug kaw, thiab cov ntsia hlau conveyor tsuas yog pib tawm cov ntaub ntawv raw, thiab cov khoom hnyav poob rau lub sijhawm no. Tom qab lub teev pib ua hauj lwm rau ib lub sij hawm, lub net nyhav ntawm cov ntaub ntawv raw nyob rau hauv lub net hnyav warehouse yuav txo. Thaum qhov tsawg kawg nkaus raw khoom txoj hauj lwm mus txog ntawm t2, raw khoom valve yuav qhib dua. Lub sij hawm ntawm t1 mus rau t2 muab lub sij hawm voj voog rau hom quab yuam. Tom qab ib lub sij hawm, qhov hnyav ntawm cov khoom siv raw hauv lub net hnyav warehouse yuav nce. Thaum lub sij hawm t3 mus txog qhov siab tshaj plaws raw khoom txoj hauj lwm dua, cov khoom raw li qub kaw, thiab lub sij hawm los ntawm t2 mus rau t3 yog rov qab nyob rau hauv lub zog mov lub sij hawm, thiab qhov ceev ratio ntawm cov ntsia hlau conveyor yog soj ntsuam raws li lub instantaneous ntws. , thiaj li ua tiav lub voj voog khoom ruaj khov. Thaum lub sij hawm, qhov sib piv ceev ntawm cov ntsia hlau conveyor tswj qhov ceev piv ua ntej lub sij hawm pib ntawm lub voj voog thiab tsis hloov, thiab yog muab los ntawm qhov ntsuas qhov ntim tas li. Vim hais tias lub taub hau hnyav hnyav sib txuas ua ke cov khoom hnyav thiab cov ntaub ntawv zoo li qub, thiab sib txuas ua ke kev cuam tshuam kev noj zaub mov thiab kev noj mov tas mus li, cov qauv tsim nyog rau kev sib khi, thiab tsim nyog rau cov pob zeb, cov hmoov nplej sai, pulverized thee, zaub mov, tshuaj thiab lwm yam khoom siv me me. Weighing thiab pub kev ua haujlwm tuaj yeem ua tiav qhov hnyav precision thiab linearity. Lub 2multihead weigher ua haujlwm ntawm qhov tsim nyog ntawm lub ntsiab parameter tsim qauv.

Thaum tsim cov nplai nrog qhov hnyav uas ploj lawm, nco ntsoov coj mus rau hauv tus account lub luag haujlwm tseem ceeb xws li kev pub noj ntau zaus, rov pub ntim, rov pub lub tsev khaws khoom noj, thiab rov pub noj dua. Txwv tsis pub, qhov ntsuas qhov hnyav uas ploj lawm yuav tsis ua haujlwm zoo. Piv txwv li, ib tus neeg muas zaub tau yuav ntau lub taub hau hnyav los ntawm lub chaw tsim khoom rau kev saib xyuas cov cuab yeej ntawm qhov chaw. Thaum lub sijhawm yuav khoom, tsuas yog 3 100kg hnyav sensors tau yuav.

Cov chaw tsim khoom tau xa ib tus neeg mus rau qhov chaw kom paub tias tus neeg siv khoom cov khoom siv raw yog boric acid tov, qhov txheeb ze ntom ntom yog 1510kg / m3, qhov siab tshaj plaws tag nrho yog 36kg / h, thiab qhov sib xyaw tag nrho yog 21 ~ 24kg / h. Tag nrho cov ndlwg yog me me, lub hopper siv peb 100kg hnyav sensor txhawb cov ntsiab lus, thiab cov tsom xam hopper muaj peev xwm loj. Nws yog ib qho teeb meem unscientific hauv kev xaiv qauv. Lwm qhov teeb meem yog tias lub hopper txuas nrog lub tshuab nrog kev co thaum lub sijhawm teeb tsa. Peb tuaj yeem xaiv 15 ~ 20 zaug / teev raws li cov qauv hauv qab no tau pom zoo ua haujlwm dhau los thaum qhov kev thov loj dua, thiab qhov hnyav ntawm txhua qhov khoom ntxiv yog 36/15 ~ 36/20, uas yog, 1.9kg ~ 2.4kg, Qhov hnyav ntawm cov khoom siv los ntawm txhua qhov hnyav sensor yog tsawg dua 1 kg, thiab qhov ntsuas qhov tsim nyog yog li 0.5 ~ 1%.

Feem ntau, qhov ntsuas qhov tsim nyog ntawm qhov ntsuas qhov hnyav yuav tsum yog tsawg kawg 10 ~ 30% kom ntseeg tau tias qhov hnyav dua. Raws li qhov hnyav ntawm cov khoom siv raw 2.4kg thiab qhov hnyav ntawm cov khoom siv raw khoom thiab cov khoom siv raw khoom thiab cov khoom siv (ntsia hlau conveyor, thiab lwm yam), tag nrho qhov hnyav yog li 10kg. Thaum peb siv lub ntsuas qhov hnyav, qhov ntsuas qhov ntsuas ntawm txhua qhov ntsuas qhov hnyav tuaj yeem raug xaiv los ntawm 5kg txog 10kg. Hauv lwm lo lus, qhov ntau ntawm qhov yuav 100kg sensor yog nce los ntawm 10 ~ 20 npaug, kev ntseeg siab ntawm lub taub hau hnyav hnyav yog qhov tsis zoo, thiab qhov hnyav hnyav yog tsawg.

Cov ntaub ntawv no qhia tau hais tias lub tswv yim tsim ntawm multihead weighter yuav tsum ua raws li tus qauv tsim qauv, thiab qhov tseem ceeb ntawm cov cuab yeej siv tshuab thiab kev ua haujlwm ntawm multihead weighter tsis tuaj yeem txiav txim siab yam tsis muaj kev ntsuas. 3multihead weighter kev ua haujlwm tseem ceeb ntawm cov qauv tsim kev suav. 3.1 Kev suav ntawm kev pub noj ntau zaus.

Rau ntau lub taub hau hnyav, qhov loj dua qhov sib piv ntawm lub voj voog lub zog (lub sij hawm piv = lub voj voog khoom siv hluav taws xob / rov muab lub voj voog) hauv txhua lub voj voog, qhov zoo dua, feem ntau nws yuav tsum tshaj 10: 1. Qhov no yog vim qhov tseeb hais tias hom quab yuam muab lub sij hawm voj voog nrog ntau dua precision dua lub sij hawm rov muab khoom dua, thiab ntev dua lub zog hom muab lub sij hawm voj voog, qhov siab dua tag nrho cov precision ntawm multihead weighter. Lub circulatory system zaus ib lub sij hawm ntawm lub multihead weighter yog feem ntau qhia raws li lub circulatory system zaus ib teev twg thaum qhov kev thov loj dua, uas yog, lub sij hawm / h.

Noj qhov kev thov loj dua ib teev raws li tus qauv, qhov kev thov lub sij hawm tas li ntawm ib chav tsev (piv txwv li, ib ob) yog qhov ua ntej. Qhov tsawg dua qhov zaus ntawm lub voj voog, qhov ntau npaum li cas ntawm txhua qhov kev pub mis, qhov ntau dua qhov muaj peev xwm thiab cov khoom hnyav ntawm lub tsev khaws khoom hnyav, qhov qis dua qhov ntsuas qhov hnyav ntawm lub xeev tsis muaj zog los ntawm kev siv ntau theem ntawm cov cell load, qhov ntau dua. zaus ntawm cov hlab ntsha, qhov ntau dua qhov pub mis txhua lub sijhawm. Qhov qis dua, qhov me me ntawm lub peev xwm thiab qhov hnyav ntawm lub net hnyav warehouse, thiab qhov siab dua qhov kev siv me me ntawm cov khoom thauj khoom los ntsuas lub xeev qhov hnyav. Txawm li cas los xij, qhov zaus ntawm lub voj voog yog siab dhau lawm, cov cuab yeej siv tshuab pub mis feem ntau raug txiav, thiab cov tswj vaj huam sib luag ntawm ntau lub taub hau hnyav feem ntau hloov ntawm lub zog pub mis lub sij hawm thiab lub sij hawm pub mis, thiab nws tsis zoo heev.

Raws li kev ua haujlwm tsis tu ncua, feem ntau ntawm lub xeev tsis hnyav muab cov txheej txheem software, tshwj xeeb tshaj yog rau cov hmoov av thiab cov kua dej tsis zoo, qhov zaus ntawm cov khoom siv tau raug xaiv li 15 ~ 20 zaug / teev thaum qhov kev thov loj. Thaum qhov kev thov qis dua qhov kev thov loj dua, qhov zaus ntawm cov khoom siv rov qab tau txo qis, thiab cov khoom siv quab yuam-hom khoom lag luam suav nrog qhov loj dua, uas yog qhov tsim nyog rau kev txhim kho qhov tseeb. Tsuas yog kev ua haujlwm tsis tu ncua, qee cov ntawv thov uas muab qhov tshwj xeeb qis tag nrho, txawm hais tias lub tsev khaws khoom muaj peev xwm me me, lawv tseem tuaj yeem khaws cov ntaub ntawv raw khoom tau muab rau ntau tshaj 1 teev, thiab lub sijhawm muab ntau tshaj 1 teev.

Cov xwm txheej hauv qab no: Loj dua muab tag nrho ntws ntawm 2kg / h. Cov khoom siv raw deposition piv yog 803kg / m3. Tag nrho cov khiav ntawm qhov ntim loj pub mis yog 2/803 = 0.0025m3 / h.

Yog tias lub tsev khaws khoom muaj peev xwm yog 0.01m3 (kwv yees sib npaug rau 250Mm×250 Mm×Qhov luaj li cas ntawm lub cubic meter warehouse zoo li 250Mm) yog txaus rau 2h ~ 3h ntawm raw khoom siv, thiab txhua raw khoom siv tsis pub tshaj 10kg, yog li tsis siv neeg raw cov ntaub ntawv, thiab manpower raw cov ntaub ntawv yuav tsum tau txiav txim. Cov kev cai tsim khoom, tab sis tag nrho cov khiav linearity yog me ntsis qis. 3.2 Xam lub ntim ntim dua. Tom qab xaiv qhov refill zaus, nws tuaj yeem ntsuas qhov ntim ntim thiab cov khoom ntim tag nrho.

Ua ib qho piv txwv ntawm ntau lub taub hau hnyav: qhov loj dua muab tag nrho ntws ntawm 270KG / teev. Qhov ntom ntom ntawm cov khoom siv raw yog 485kg / m3. Tag nrho cov ntws ntawm qhov ntim loj pub mis yog 270/480 = 0.561m3 / h.

Ntawm tus nqi xa khoom loj dua, qhov zaus ntawm kev xa rov qab raug xaiv yog 15 zaug / teev. Kev suav txheej txheem ntawm reloading ntim: reloading ntim = loj ntxiv tus nqi (kg / h)÷Qhov ceev (kg / m3)÷Rov nkag zaus (rov nkag zaus / h) Hauv qhov no, qhov ntim rov qab rov qab = 270÷480÷Luas = 0.0375 m3. 3.3 Net nyhav warehouse muaj peev xwm xam.

Lub peev xwm net hnyav warehouse muaj peev xwm ntawm cov qauv tsim yuav tsum tshaj qhov xam qhov hnyav warehouse peev. Qhov no yog vim lub net hnyav warehouse yuav inevitably muaj cov ntaub ntawv raw thiab dawb qhov chaw nyob rau sab saum toj ntawm lub warehouse thaum lub net hnyav warehouse pib lub net hnyav warehouse. Yog tias txhua tus account rau 20%, thiab qhov hnyav ntawm lub tsev khaws khoom muaj peev xwm muab faib los ntawm 0.6, qhov tsim nyog lub tsev khaws khoom muaj peev xwm tuaj yeem tau txais.

Qhov kawg xaiv net hnyav warehouse ntim yuav tsum glossy raws li qhov ruaj khov ntim ntim. Kev suav txheej txheem ntawm reloading ntim: net hnyav warehouse peev = net hnyav ntim÷k. Nyob rau hauv cov mis: k yog qhov kwv yees qhov nyiaj tshuav ntawm cov khoom siv raw khoom, uas tuaj yeem yog 0.4 ~ 0.7, thiab 0.6 yog npaj.

Hauv qhov piv txwv no, net hnyav warehouse peev = 0.0375÷0.6 = 0.0625 m3. Thaum lub ntim ntawm lub warehouse zoo li 0.6m3, 0.8m3, 1.0M3 thiab lwm yam specifications thiab qauv, lub gloss yuav tsum yog 0.08m3 upward, thiab lub peev xwm ntawm lub warehouse hnyav yuav tsum yog 0.08m3. 3.4 Ntsuas qhov rov nruab tus nqi.

Lub multihead weigher yog muab los ntawm ib tug tsawg-precision tsau muaj peev xwm txoj kev nyob rau hauv lub reloading voj voog lub sij hawm, yog li lub reloading tus nqi ntawm lub reloading tshuab yog teev kom ceev (feem ntau, nws yuav tsum tau tswj nyob rau hauv 5s ~ 20s). Kev suav cov txheej txheem ntawm reloading tus nqi: recapitalization tus nqi = [recapitalization ntim (m3)÷Reinvestment lub sij hawm (s)×60 (s / min)] + [loj ntim peev peev tag nrho ntws (m3 / h)÷60 (min / h)] Hauv Kev Ua Haujlwm 2, tus nqi rov ntxiv muaj 2 yam khoom tshiab, thawj yam khoom tshiab yog tus nqi ntxiv raws li qhov rov ntxiv ntim, thiab cov khoom tshiab thib ob feem ntau tsis quav ntsej los ntawm ntau tus neeg, qhia tias tib yam Tus nqi sib ntxiv ntawm lub sij hawm, cov khoom siv raw uas yuav tsum tau sau qhov no thaum ntxiv dua. Raws li tus nqi, tus nqi rov qab yog kwv yees li 30 npaug ntawm tus nqi ntxiv loj dua. Nyob rau hauv lwm yam lus, raws li tus nqi no, thaum kwv yees tus nqi rov qab noj ntawm lwm yam net hnyav uas ploj lawm teev, nws muaj peev xwm kwv yees li ntawm 25-40 lub sij hawm qhov loj ntxiv tus nqi. .
