A hmoov feederyog ib qho tseem ceeb ntawm cov khoom siv nyob rau hauv ib qho kev lag luam kev lag luam uas yuav tsum tau muaj kev tswj hwm thiab kev noj zaub mov zoo ntawm cov hmoov qhuav rau hauv cov txheej txheem. Powder feeders yog siv dav hauv kev lag luam xws li tshuaj, khoom noj thiab dej haus, tshuaj, yas thiab roj hmab, hlau thiab mining, thiab lwm yam. Nyob rau hauv no blog ncej, peb yuav muaj ib tug saib nyob rau hauv-tob saib dab tsi hmoov feeders yog, vim li cas lawv tseem ceeb nyob rau hauv cov ntaub ntawv tuav, dab tsi hom thiab cov khoom tseem ceeb yog dab tsi thiab yuav ua li cas lawv ua hauj lwm kom ntseeg tau xa hmoov ntawm tus nqi.
Txhais thiab qhov tseem ceeb ntawm Powder Feeders
Powder feeders, tseem hu ua cov khoom siv qhuav qhuav, yog tsim tshwj xeeb rau kev tuav cov hmoov av uas muaj dej ntau. Lawv lub hom phiaj yog pub cov hmoov nplej ntawm tus nqi tswj thiab ruaj khov los ntawm lub hopper rau hauv cov txheej txheem rau kev thauj mus los ntxiv, sib tov, ntim, tshuaj tiv thaiv lossis lwm yam kev siv cov hmoov tuav (Cséfalvay, 2018). Qhov tseeb, sib xws thiab kev ntseeg siab ntawm kev pub mis yog qhov tseem ceeb rau ntau cov txheej txheem, vim tias qhov kev hloov pauv ntawm cov kev txwv no tuaj yeem cuam tshuam tsis zoo rau cov khoom lag luam, kev ua haujlwm zoo thiab ntau dua. Tej yam zoo li bulk ceev, particle loj faib, cov ntsiab lus noo, ntws cov khoom thiab lwm tus cuam tshuam nrog cov yam ntxwv nyuaj rau kev pub mis. Powder feeders kov yeej cov no siv cov qauv tsim tshwj xeeb thiab hopper-reservoir kev npaj kom ua kom du, tswj cov hmoov tawm los ntawm kev hloov pauv tus nqi pub, ua kom cov haujlwm ua haujlwm tau zoo.
Hom Powder Feeders
Muaj ntau ntau hom hmoov feeders tsim rau ntau lub hom phiaj, hmoov khoom, muaj peev xwm, pub mis thiab lwm yam. Plaub yam tseem ceeb yog:
Volumetric Feeders: Cov no pub cov ntim ntim cov hmoov hauv ib lub sijhawm ntawm tus nqi tsis tu ncua, siv cov paddles rotating, screws, rollers lossis vibrating tais. Lawv yooj yim rau kev khiav lag luam thiab haum rau cov hmoov dawb ntws (Coperion, 2020).
Gravimetric Feeders: Cov hmoov pub no raws li qhov hnyav ntawm cov khoom ntws mus tas li, tso cai rau tus nqi pub dawb hauv grams ib teev. Lawv siv cov cell load thiab tswj cov hmoov ntws tau txais. Lawv zoo heev rau cov txheej txheem batch xav tau qhov tseeb (Schenck Process, 2020).
Venturi Feeders: Cov aerodynamically nrawm cov hmoov siv compressed cua / roj los ntawm kev txwv hu ua venturi lossis eductor. Lawv tuav cov nplaum nplaum, dej nyab zoo (Volkmann USA, 2022).
Pneumatic Conveying Feeders: Cov no siv cov cua compressed tuaj tos thiab xa cov hmoov hauv kev ncua los ntawm cov kav dej ntawm kev kub ceev rau hauv cov hlab ntsha kaw. Lawv zoo tagnrho rau cov tshuaj lom thiab phom sij (Marietti, 2022).
Cheebtsam ntawm Powder Feeder System
Lub hmoov feeder suav nrog ntau yam khoom tsim kho kom ntseeg tau cov hmoov tuav. Cov no suav nrog (Bulk Handling Global, 2015):
• Hopper/Reservoir – Tuav cov hmoov ntau saum lub feeder. Cov qauv hopper tshwj xeeb txo qis kev sib txuas thiab nas-qhov teeb meem.
• Feeder Lub Cev - Npog thiab txhawb kev pub mis (paddles, screws, rollers thiab lwm yam) uas tswj cov hmoov paug tawm.
• Lub tshuab pub mis - Ncaj qha tswj thiab teeb tsa tus nqi noj hmoov, tsim kom haum cov yam ntxwv ntawm hmoov.
• Tsav Unit – Lub cev muaj zog, gearbox thiab tswj uas lub hwj chim ntawm kev pub mis.
• Tswj & Sensors – Tswj thiab saib xyuas feeder ceev, optimize pub nqi thiab interface nrog cov txheej txheem automation.
• Cov khoom siv hauv qab - thauj cov hmoov los ntawm lub feeder rau cov txheej txheem tom ntej los ntawm cov chutes, kav dej lossis pneumatic conveying.
Cov ntsiab cai ntawm kev ua haujlwm
Whilst hom feeder muaj ntau lub tswv yim rau kev txav cov hmoov, lawv txhua tus ua haujlwm los muab cov khoom tso tawm los ntawm lub hopper ntawm tus nqi kho tau rau hauv cov txheej txheem ntws. Gravimetric feeders muaj ib qho kev tswj xyuas ntxiv uas siv cov xov tooj ntawm tes kom sib txawv feeder ceev thiab ua tiav cov khoom noj ceev ceev hauv qhov hnyav / teev (Schenck Process Group, 2017). Cov kauj ruam tseem ceeb hauv cov hmoov feeder txoj haujlwm ua haujlwm yog:
1. hmoov yog loaded rau hauv ib tug tshwj xeeb tsim hopper uas tso cai rau kev tswj ntws los ntawm lub ntiajteb txawj nqus mus rau hauv lub feeder mechanism.
2. Lub feeder mechanism (paddles, screws, rollers thiab lwm yam) yog preset khiav ntawm ib tug ceev uas txhais lub volumetric/gravimetric pub tus nqi.
3. Raws li cov hmoov nkag mus rau hauv lub feeder, lub tshuab tsis tsuas yog txav nws ntawm qhov ceev no tab sis kuj tseem ua haujlwm txiav thiab deaerates cov hmoov kom nws cov dej tsis sib xws.
4. Rau gravimetric feeders, load cell signals tsis tu ncua ntsuas hmoov qhov hnyav tawm thiab hloov kho mechanism ceev kom tswj tau tus nqi instantaneous pub.
5. Powder tawm lub feeder rau hauv cov khoom siv downstream ntawm qhov xav tau nyob ruaj khov rau kev hloov mus tas li mus rau qhov kawg-daim ntawv thov.
Hauv cov ntsiab lus, hmoov feeders siv ntau yam kev tsim kho tshuab, kho kom haum rau txhua cov hmoov los muab kev ntseeg siab, tswj kev pub noj thiab zoo sib xws ntawm cov hmoov nplej uas siv cov hmoov nplej sib txawv. Advanced digital tswj thiab kev sib txuas lus pab txhawb kev sib koom ua ke feeder zoo, automation thiab tau txais cov ntaub ntawv. Cov khoom siv tsim tau zoo yog li sawv cev rau qhov tseem ceeb ntawm kev xa cov raug thiab ua haujlwm zoo rau kev tsim cov hmoov nplej.
