Kev sib xyaw ua ke yog hais txog kev ntsuas kev ntsuas thiab kev sib xyaw ua ke ntawm ntau yam khoom siv-xws li cov cement, nplua aggregate (xuab zeb), coarse aggregate (crushed pob zeb los yog gravel), dej, admixtures, thiab ntxiv cementitious cov ntaub ntawv (xws li yoov tshauv, av granulated blast silace) {{1}, urnace urnace, thiab lwm yam.)-thaum lub sijhawm tsim cov pob zeb ua vaj tse, raws li kev tsim ua vaj tse ua ntej (CMD).
Batching yog cov txheej txheem tseem ceeb hauv kev tsim cov pob zeb ua haujlwm. Nws qhov tseeb ncaj qha cuam tshuam rau kev ua haujlwm thiab homogeneity ntawm cov pob zeb tshiab, nrog rau lub zog, durability, thiab ntim ruaj khov ntawm cov pob zeb tawv tawv. Los ntawm qhov kev xav ntawm kev tswj kom zoo, cov txheej txheem batching xav tias qhov tseem ceeb ntawm "kev hloov pauv tus nqi tsim nyog rau hauv cov khoom siv tiag tiag," ua tus choj ntawm kev sib xyaw tsim thiab cov txheej txheem sib xyaw.
Peb txoj kev ntawm kev ua vaj tse pob zeb
Raws li cov qauv ntsuas sib txawv, cov txheej txheem kev sib tsoo pob zeb tuaj yeem muab faib ua peb hom hauv qab no.
1. Random Volumetric Batching
Txoj kev no tsis siv cov cuab yeej ntsuas ntsuas. Nws tsuas yog nyob ntawm tus neeg teb xov tooj qhov kev paub dhau los, siv shovels lossis thoob (xws li "Ghamelas" lossis cov ntim khoom yooj yim) los kwv yees cov khoom faib. Txoj kev no tsis muaj lub hauv paus kev tshawb fawb. Qhov kev faib ua feem yuam kev yog loj thiab tswj tsis tau. Nws tsis tuaj yeem xyuas kom meej tias cov pob zeb ua tiav lub zog tsim thiab ua haujlwm ntev. Nyob rau hauv tam sim no kev specifications, random volumetric batching yog kom meej meej txwv rau zus tau tej cov structural pob zeb.
2. Volumetric Batching
Volumetric batching siv cov thawv ntsuas ntsuas (feem ntau hu ua "farmas" lossis "gauge boxes") rau kev ntsuas. Nyob rau hauv cov xwm txheej zoo tagnrho, qhov ntim ntawm lub thawv ntsuas yog sib npaug rau qhov ntim ntawm ib lub hnab ntawm cov cement (50 kg, kwv yees li 35 litres), los yog ntau qhov sib npaug. Fine aggregate thiab coarse aggregate yog batched los ntawm ntim siv gauge thawv. Dej yog ntsuas los ntawm lub ntsuas dej los yog ruaj khov - ntim dej ntim.
Technical limitations:Kev hloov pauv ntawm cov dej noo ntawm cov khoom sib xyaw ua rau muaj kev hloov pauv loj hauv lawv cov ntim ntau, yog li qhia txog kev ntsuas qhov tsis raug. Tsis tas li ntawd, kev ua haujlwm yuav tsum tau ua ntawm "sau tsis dhau" yog qhov nyuaj rau kev ua raws li kev tsim kho tiag tiag. Yog li ntawd, volumetric batching tsuas yog siv tau raws li kev txwv rau me me, tsis yog - cov haujlwm tseem ceeb uas qhov hnyav batching tsis muaj.
3. Nyhav Batching
Qhov hnyav batching txhais tau hais tias tag nrho cov khoom siv (cement, aggregates, cov khoom siv ntxiv) thiab cov khoom ua kua (dej, cov khoom sib xyaw) yog ntsuas los ntawm qhov hnyav (kg lossis tons). Txoj kev no yog cov thev naus laus zis tseem ceeb hauv kev lag luam thiab kev tsim vaj tsev tam sim no. Nws kuj yog tus qauv kev coj ua pom zoo los ntawm ntau yam kev qhia tshwj xeeb.Raws li qib ntawm automation, hnyav batching tuaj yeem muab faib ua:
Manual hnyav batching:Txhua feem yog hnyav manually. Haum rau cov haujlwm me me heev - nplai.
Semi- tsis siv neeg hnyav batching:Tus neeg teb xov tooj manually qhib lub qhov rooj tawm. Lub rooj vag kaw cia li thaum lub teeb hnyav ncav cuag.
Tag nrho tsis siv neeg hnyav batching:Lub microprocessor tswj qhov system cia li ua tiav txhua qhov ntsuas, pub mis, thiab sau cov ntaub ntawv raws li kev sib xyaw tsim. Qhov no yog siv dav hauv kev npaj -cov pob zeb sib xyaw ua ke thiab loj ntawm - cov nroj tsuag batching.
Qhob Batching txheej txheem ntws
Nyob rau hauv tag nrho tsis siv neeg los yog ib nrab - tsis siv neeg batching cog tej yam kev mob, lub pob zeb batching txheej txheem feem ntau muaj xws li cov kauj ruam hauv qab no:
Cov Khoom Siv Npaj thiab Calibration
Txheeb xyuas cov khoom sib tov, cov thawv ntim khoom, qhov hnyav, thiab cov khoom siv thauj khoom. Zero los yog calibrate qhov hnyav sensors.
Kev noj qab haus huv
Pub cov ntaub ntawv nyob rau hauv ib tug preset order (coarse aggregate → fine aggregate → cement → ntxiv cov ntaub ntawv → dej → admixtures). Qhov no tiv thaiv cov cement los ntawm kev lo rau ntawm phab ntsa tov khoom thiab ua kom zoo sib xws.
Feeding Rate Control
Kho qhov qhib lossis zaus ntawm txhua lub qhov rooj tawm. Tsis txhob dhau - kam rau siab vim dhau - noj ceev lossis txo qis vim yog dhau - pub mis qeeb.
Txheej Txheem Saib Xyuas thiab Cov Lus Qhia
Sau cov ntaub ntawv tiag -lub sij hawm ntawm qhov hnyav, tus nqi ntws, thiab cov dej noo. Yuav kho cov txheej txheem (xws li, txo cov dej ntxiv raws li cov xuab zeb noo noo).
Discharge rau Mixer
Muab cov khoom ntsuas ntsuas rau hauv lub tov khoom. Nkag mus rau qhov sib xyaw ua ke.
Vim li cas Batching tseem ceeb dua li kev sib tov?
Lub counterintuitive tab sis proven technical fact yog hais tias txawm nrog ib tug zoo meej tov khoom, unqualified pob zeb tseem yuav ua tau. Qhov laj thawj tseem ceeb yog tias batching tshwm sim ua ntej sib tov. Thaum qhov kev faib ua feem ntawm cov khoom sib txawv ntawm tus nqi tsim, tsis muaj kev sib xyaw ua haujlwm tom qab tuaj yeem kho qhov yuam kev.
Tsis txaus batching raug ncaj qha ua rau cov teeb meem zoo hauv qab no:
Honeycombing thiab bugholes
Cov voids tshwm sim los ntawm qhov tsis txaus nplua aggregate los yog tsis zoo aggregate grading.
01
Kev sib cais thiab los ntshav
Cov dej txav mus rau sab saud, thiab ntxhib cov dab dej sib sau ua ke, ua rau cov khoom sib cais.
02
Permeable pob zeb
Kev tsim cov dej ntws tawm, uas ua rau cov hlau txhim kho corrosion thiab txo cov txheej txheem durability thiab kev pab lub neej.
03
Kev ua haujlwm tsis zoo
Qhuav qhuav rau kev tso kawm kom zoo, los yog ntub heev uas txo cov zog hardened.
04
Ib qho uas feem ntau saib tsis taus qhov tshwm sim yog qhov nce ntxiv ntawm cov nqi kho. Qhob nrog tsis raug batching feem ntau tsis poob tam sim ntawd. Nws deteriorates maj mam los ntawm cov kab nrib pleb, spalling, thiab zais corrosion ntawm qhov cuab lub zog. Thaum muaj teeb meem pom, tus nqi kho feem ntau yog ob peb zaug ntawm cov peev txheej qub.
Yuav Ua Li Cas Xaiv Qhov Tsim Nyog Batching Method?
Kev xaiv cov txheej txheem batching yuav tsum ua raws li plaub yam tseem ceeb hauv qab no.
Qhov project scale:Rau me me, tsis yog{0}} tej yaam num tseem ceeb, volumetric batching tej zaum yuav raug siv raws li tsawg. Rau cov khoom siv xws li lub hauv paus ntawm rau - zaj dab neeg lub tsev, hnyav batching yog yuav tsum tau.
Tus nqi tsim khoom xav tau:Thaum lub sijhawm ua haujlwm nruj, lub tshuab ua haujlwm tsis siv neeg tuaj yeem ua tiav cov zis ntawm ob peb cubic meters ib feeb.
Cov xwm txheej ua haujlwm:Thaum cov neeg ua haujlwm txawj ntse tsis tshua muaj nqi lossis kim, lub tshuab ua haujlwm tsis siv neeg txo qis tib neeg -txog qhov sib txawv.
Kev txwv nyiaj txiag:Kev tuav batching tau qis dua thawj zaug peev tab sis muaj kev pheej hmoo siab dua ntawm kev rov ua haujlwm thiab teeb meem zoo. Ib qho kev cog qoob loo tsis siv neeg muaj tus nqi siab dua tab sis muab sijhawm ntev - thiab kev ruaj ntseg zoo ib yam.
Xaus
Qhob batching tsis yog ib qho yooj yim "hnyav" ua haujlwm. Nws yog cov txheej txheem engineering nrog cov kev qhia meej meej, txheej txheem txheej txheem, thiab kev tswj xyuas kom zoo.
Nyob rau hauv niaj hnub pob zeb technology, batching raug ncaj qha txiav txim seb lub theoretical mix tsim yuav hloov mus rau hauv tiag tiag engineering kev ua tau zoo.
Txawm hais tias nyob rau hauv ib qho kev npaj -cov cog pob zeb sib xyaw lossis ib qho ntawm - thaj chaw batching cog, tsim kom muaj lub suab batching zoo tswj system yog qhov tseem ceeb. Batching yuav tsum tau ua nruj me ntsis los ntawm txoj kev hnyav batching. Kev ntsuas kam rau ua yuav tsum tau tswj nyob rau hauv cov kev txwv uas tau teev tseg los ntawm cov qauv.
Cov kev coj ua no yog qhov tsim nyog yuav tsum tau ua ua ntej kom ntseeg tau lub sijhawm ntev - lub neej kev nyab xeeb ntawm cov qauv tsim. Nruab nrab ntawm kev sib xyaw tsim thiab siv tshuab, batching yog qhov chaw tswj xyuas qhov zoo uas tso cai rau tsis muaj qhov tsis meej.
