Av nplaum xuab zeb ua tshuab

Av nplaum xuab zeb ua tshuab
Cov av nplaum xuab zeb ua tshuab yog ib kauj ruam tseem ceeb hauv cov txheej txheem casting, ncaj qha cuam tshuam qhov zoo ntawm castings, cov nqi tsim khoom, thiab kev tiv thaiv ib puag ncig. Cov hauv qab no muab cov txheej txheem thiab cov ncauj lus kom ntxaws txog cov tshuab no. Lub hom phiaj tseem ceeb
Cov xuab zeb siv thiab qub (muaj cov av nplaum ua tsis tiav, cov hmoov av, cov khoom tsis huv, thiab lwm yam) yuav raug ua tiav los kho nws cov khoom, thiab tom qab ntawd tov nrog cov xuab zeb tshiab, binder (cov av nplaum loj), thiab cov khoom siv ntxiv (coal hmoov, thiab lwm yam) los npaj cov xuab zeb tshiab uas ua tau raws li cov txheej txheem molding. Qhov no yog cov txheej txheem rov ua dua tshiab.
Cov txheej txheem khiav daim duab (kaw- voj voog voj voog)
Sanding → Crushing → Sib cais sib nqus → Kev tshuaj ntsuam → (Cua txias thiab ua ntej - kho cov xuab zeb qub) → Sand regeneration (theem tseem ceeb) → Ntxiv cov xuab zeb tshiab / cov khoom siv → Mixed sand → Molding sand performance test → Molding use
Cov lus piav qhia ntxaws ntawm txhua tus txheej txheem
1. Ua ntej-kev kho mob theem
Ua ntej cov xuab zeb qub nkag mus rau hauv cov txheej txheem tsim dua tshiab, nws yuav tsum tau npaj.
Sanding thiab crushing: cais cov castings txias los ntawm pouring los ntawm cov xuab zeb pwm, thiab cov xuab zeb loj yog crushed.
Sib nqus sib cais: Siv cov khoom sib nqus sib nqus (nruas sib nqus, siv) kom tshem tau cov taum hlau, hlau ntsia hlau, ya npoo thiab burrs, thiab lwm yam uas yog ferromagnetic nyob rau hauv cov xwm, tiv thaiv cov khoom tom qab.
Kev tshuaj ntsuam: Tshem cov pob txha tseem ceeb, cov ntoo thaiv, cov xuab zeb thaiv, thiab lwm yam uas tsis yog- sib nqus los ntawm kev siv lub vibrating npo lossis ntau- lub kaum sab xis.
2. Txias thiab ua ntej -kev kho cov xuab zeb qub (theem tseem ceeb)
Qhov kub ntawm cov xuab zeb qub feem ntau yog 80-120℃. Cov xuab zeb kub kub tuaj yeem ua rau muaj ntau yam teeb meem (adhesion rau cov khoom siv, dej evaporation, cuam tshuam rau qhov zoo ntawm cov xuab zeb sib xyaw). Txoj kev ua kom txias:
Vibrating Boiling Txias txaj: Qhov feem ntau siv thiab ua tau zoo. Cua yog cua tshuab, thiab cov xuab zeb nyob rau hauv ib lub xeev kub npau npau ntawm lub vibrating phaj, thaum txias thiab tshem tawm ib co hmoov av.
Ob chav -disc cooler: Txias los ntawm kev nplawm thiab cua yog siv, thiab nws kuj muaj qhov ua ntej - sib xyaw ua haujlwm.
Rolling txias tshuab: Txias los ntawm cua txias thiab dej evaporation nyob rau hauv ib tug rotating roller.
3. Xuab zeb regeneration (core theem)
Lub hom phiaj yog tshem tawm cov av nplaum ua tsis tiav (cov av nplaum tuag) ntawm qhov chaw ntawm cov xuab zeb, uas yog tus yuam sij rau kev kho cov xuab zeb cov khoom. Raws li kev siv zog rov tsim dua tshiab, nws tau muab faib ua:
Ua ntej -theem regeneration (pab tsim dua tshiab): Tsuas yog ib nrab tshem tawm cov av nplaum ua tsis tiav los ntawm kev sib txhuam. Cov cuab yeej siv: Centrifugal rotor regeneration tshuab. Cov xuab zeb yog vibrantly rubbed thiab collided ntawm lub rotor rotor thiab liner phaj, ua rau cov av nplaum zaj duab xis tev tawm. Tsim nyog rau me me - nplai, tsawg xav tau casting factories.
Thib ob-theem rov tsim dua tshiab (muaj zog rov tsim dua tshiab): Raws li thawj- theem kev sib txhuam, ntxiv cuam tshuam lossis sib tsoo.
Kev cuam tshuam huab cua rov tsim dua tshiab: Siv siab- cua nrawm nrawm kom nrawm cov xuab zeb thiab cuam tshuam rau lub hom phiaj phaj, ua rau muaj txiaj ntsig zoo dua.
Mechanical haib regeneration: xws li ntsug los yog kab rov tav tshuab regeneration tshuab, combining kev sib txhuam, cuam tshuam thiab sib tsoo.
Thib ob -theem regenerated xuab zeb muaj qhov zoo thiab tuaj yeem siv rau kev tsim cov xuab zeb nyuaj lossis ua cov xuab zeb nto.
4. Cua sib cais thiab tshem tawm plua plav
Cua sib cais: Cov xuab zeb regenerated nkag mus rau hauv cov khoom sib cais cua, siv cov cua ntws los cais cov hmoov zoo (tsuas yog cov av nplaum tuag thiab cov hmoov tshauv) los ntawm cov xuab zeb uas tsim nyog.
Kev tshem tawm plua plav: Tag nrho cov txheej txheem yog nruab nrog lub hauv paus muaj zog tshem tawm plua plav tawm, khaws cov plua plav tawm ntawm ntau qhov chaw los xyuas kom muaj kev tiv thaiv ib puag ncig thiab kev ua haujlwm huv.
5. Cov xuab zeb sib xyaw thiab cov khoom xyaw
Sib tov cov xuab zeb regenerated, ntxiv xuab zeb tshiab (kwv yees li 5-15%), bentonite (av nplaum), thee hmoov (los yog lwm yam carbonaceous additives), thiab dej nyob rau hauv meej proportions.
Cov cuab yeej tseem ceeb: Kev sib tov sib xyaw (ntau npaum, sib xws).
Tswj cov tub ntxhais kawm: Cov xuab zeb hauv online ntsuas kev ua tau zoo (xws li tus nqi compactness, cov ntsiab lus noo noo, lub zog tswj), kho cov dej ntxiv thiab cov khoom siv ntxiv cov nyiaj hauv lub sijhawm raws li cov txiaj ntsig kev xeem kom ua tiav kaw - voj tsis siv neeg tswj.
6. Xuab zeb homogenization thiab kev thauj mus los
Cov xuab zeb sib xyaw ua ke yuav tsum tau muab tso rau hauv homogenize (cia cov dej noo nkag mus rau qhov sib npaug) thiab tom qab ntawd thauj los ntawm txoj siv los yog pneumatic conveying tshuab mus rau lub rooj cob qhia molding.
Txheej txheem hom thiab xaiv
Raws li kev sib txawv ntau lawm thiab cov xuab zeb xav tau, muaj ob txoj hauv kev tsim:
Centralized processing system: Haum rau loj - nplai, ib zaug - cov khoom lag luam kab (xws li tsheb castings). Tag nrho cov xuab zeb qub yog centralized ua tiav, nrog cov txheej txheem compact thiab siab automation, thiab yooj yim tswj.
Chav ua txheej txheem: Haum rau ntau- ntau yam, me me-batch rhiav (xws li cov cuab yeej siv tshuab, tshuab hnyav castings). Txhua txoj kab molding yog nruab nrog ib qho kev ua haujlwm ntawm cov xuab zeb ywj pheej, nrog kev ua kom muaj zog thiab tsis muaj kev cuam tshuam.
Cov ntsiab lus tseem ceeb thiab kev tswj xyuas kom zoo Cov ntsiab lus bentonite zoo thiab cov ntsiab lus ntawm cov hmoov hmoov zoo: yuav tsum muaj kev ntsuam xyuas tsis tu ncua (xws li methylene xiav titration method), los coj cov nqi ntxiv ntawm cov bentonite tshiab thiab cov hmoov thee.
Cov ntsiab lus av nkos (cov ntsiab lus zoo hmoov): Yuav tsum tswj qis dua 12% -16%, vim tias cov ntsiab lus ntau dhau yuav cuam tshuam rau kev ua haujlwm ntawm cov xuab zeb molding.
Poob ntawm ignition: Reflects tag nrho cov nqi ntawm combustibles nyob rau hauv molding xuab zeb, thiab yuav tsum tau tswj hauv qab no 3% -5%.
Particle loj tis: Ua kom ruaj khov kom ntseeg tau tias 透气性和 nto tiav ntawm cov xuab zeb molding.
Cov ntsiab lus dej: Feem ntau tswj tau ntawm 2.0% -3.5%, uas yog "tus ntsuj plig" ntawm cov xuab zeb molding thiab yuav tsum tau tswj kom raug.
Compaction tus nqi: Qhov feem ntau intuitive hauv internet tswj parameter, xav txog qhov qhuav- ntub thiab viscosity lub xeev ntawm cov xuab zeb, feem ntau tswj ntawm 35%-45%.
Txoj kev loj hlob
Kev txawj ntse thiab cov ntaub ntawv loj: Siv cov sensors thiab Internet of Things thev naus laus zis, tiag tiag- lub sijhawm saib xyuas txhua yam txheej txheem, los ntawm kev txheeb xyuas cov ntaub ntawv loj los kwv yees lub xeev ntawm cov xuab zeb molding, ua tiav kev tiv thaiv kev saib xyuas thiab kev tswj kom zoo.
Kev ua haujlwm siab thiab txuag hluav taws xob: Cov cuab yeej siv tau tsim los rau qhov loj - nplai, siv hluav taws xob tsawg, thiab hnav tsis tshua muaj. Kev siv cov khib nyiab kub los ntawm cov xuab zeb kub.
Txhim khu kev tiv thaiv ib puag ncig: Kev sau thiab kho cov qauv rau cov plua plav thiab cov pa pa (xws li VOCs) tau nruj zuj zus.
Flexibility: Unitized thiab modular tsim, yoog raws li kev lag luam xav tau ntau yam thiab cov khoom me me. Cov ntsiab lus
Cov av nplaum xuab zeb ua thev naus laus zis yog cov txheej txheem kev ua haujlwm nyuaj uas sib koom ua ke cov tshuab, kua dej, tswj kev tswj hwm thiab cov ntaub ntawv tshawb fawb. Nws lub tswv yim tseem ceeb yog "kev lag luam ncig", txhawm rau txo qis kev siv cov xuab zeb tshiab thiab cov khoom pov tseg los ntawm kev rov tsim dua tshiab.
