Dab tsi yog qhov Wet Trommel Screen?
A ntub dej trommel screen, feem ntau tsuas yog hu ua atrommellos yog arotary scrubber, yog lub tshuab tshuaj ntsuam xyuas tshuab siv los cais cov ntaub ntawv los ntawm qhov loj me nyob rau hauv lub xub ntiag ntawm dej. Nws muaj lub nruas cylindrical uas tig thiab inclined, nrog cov dej nozzles ntsia hauv. Kev sib xyaw ua ke ntawm tumbling nkaus thiab dej ua rau nws muaj txiaj ntsig zoo rau kev tuav nyuaj, nplaum, av nplaum- nplua nuj, lossis cov khoom tsis huv uas yuav yooj yim dig muag (clog) ib txwm vibrating npo.
Nws Ua Haujlwm Li Cas?
Lub hauv paus ntsiab lus ntawm kev khiav hauj lwm yog ncaj nraim tab sis muaj txiaj ntsig zoo:
Pub:Cov khoom siv raw (piv txwv li, av, gravel, mined ore, cov khoom pov tseg hauv nroog) yog pub rau hauv qhov siab kawg ntawm kev sib hloov, me ntsis inclined nruas.
Rotation thiab Tumbling:Raws li lub nruas rotates, cov khoom yog nqa los ntawm sab hauv lifters (flights) thiab ces cascades down. Qhov kev ua haujlwm tumbling no rub tawm thiab rhuav tshem cov khoom siv agglomerated (xws li cov pob av nplaum).
Ntxuav:Dej tsis tu ncua los ntawm cov nozzles raws qhov ntev ntawm lub nruas. Cov dej no saturates cov khoom, dissolving av nplaum, thiab ntxuav tawm cov kab mob thiab cov khoom zoo.
Kev tshuaj ntsuam:Lub nruas nws tus kheej ua raws li lub vijtsam. Lub plhaub cylindrical yog perforated nrog qhov ntawm qhov loj me. Raws li cov khoom nkag mus rau hauv lub nruas, cov khoom me me thiab slurry (ib qho sib xyaw ntawm dej thiab nplua) dhau los ntawm cov qhov.
Kev sib cais:
Oversize Material (Screen Overs):Qhov loj, ntxuav pob zeb, khib nyiab, los yog cov khoom huv si uas tsis tuaj yeem hla lub qhov mus rau lub nruas ntev thiab tawm mus rau qhov kawg.
Undersize Khoom & Slurry (Screen Throughs):Cov khoom zoo (xuab zeb, silt, av nplaum) thiab dej dhau los ntawm qhov screen qhov thiab tau sau rau hauv lub pas dej lossis hauv qab lub nruas.
Cov ntsiab lus tseem ceeb
Nruas / Lub tog raj kheej:Lub cev tseem ceeb, feem ntau yog ua los ntawm cov hlau muaj zog nrog ib ntu perforated screen. Qhov loj thiab tus qauv ntawm lub qhov txiav txiav txiav txiav -point.
Tsav System:Muaj lub cev muaj zog, iav reducer, thiab trunnion log los yog cov menyuam uas txhawb nqa thiab tig lub nruas.
Ncej:Cov qauv ruaj khov uas txhawb nqa tag nrho lub rooj sib txoos.
Internal Lifters (Flights):Longitudinal tuav los yog angled daim hlau nyob rau sab hauv ntawm lub nruas uas nqa thiab tso cov khoom los txhim kho qhov kev txhuam thiab tumbling.
Dej System:Xws li lub twj tso kua dej, cov kav dej, thiab cov kab tsuag tsuag nrog cov nozzles khiav qhov ntev ntawm lub nruas sab hauv.
Pub Hopper:Qhov twg cov khoom yog nkag mus rau hauv lub trommel.
Discharge Chutes:Sib cais cov chutes rau cov khoom siv ntxhua khaub ncaws thiab cov slurry undersize.
Cov ntawv thov tseem ceeb
Cov ntxaij vab tshaus ntub dej yog qhov tseem ceeb hauv ntau qhov kev lag luam:
Aggregate thiab Mining:
Ntxuav thiab txhuam cov pob zeb, pob zeb, thiab xuab zeb kom tshem tawm cov av nplaum thiab cov av zoo.
Ua ntej-kev khiav haujlwm- ntawm-mine ore kom tshem tawm cov pob zeb pov tseg thiab tso cov pob zeb muaj txiaj ntsig.
Kev txhuam thiab desliming tom qab nickel ores, hlau ore, thiab lwm yam deposits.
Pov tseg Recycling thiab MRFs (Material Recovery Facilities):
Kev Tsim Kho & Demolition (C&D) pov tseg kom rov ua kom huv si.
Ua ntej-Kev kho mob ntawm Cov Khoom Siv Hauv Nroog (MSW) kom tshem tawm cov khoom seem thiab cov kab mob sib kis ua ntej kev txheeb xyuas ntxiv.
Kev kho av:Ntxuav cov av tsis huv kom cais cov pob zeb huv si thiab cov xuab zeb los ntawm cov khoom tsis zoo uas cov kab mob feem ntau ua rau.
Sand thiab Gravel Pits:Ua kom huv si, specification xuab zeb thiab aggregate rau kev tsim kho kev lag luam.
Qhov zoo ntawm Wet Trommel Screens
Kov tawv, nplaum khoom:Nws lub ntsiab kom zoo dua. Kev ua haujlwm tumbling thiab cov tshuaj tsuag dej zoo ua kom tawg thiab ntxuav av nplaum- cov ntaub ntawv khi uas yuav ua rau lwm cov ntxaij vab tshaus sai sai.
Robust thiab Durable:Kev tsim qauv yooj yim nrog tsawg qhov txav mus los ntawm cov ntxaij vab tshaus vibrating nyuaj, ua rau muaj kev ntseeg siab thiab kev saib xyuas qis dua.
Kev Ua Tau Zoo:Qhov kev ua haujlwm tumbling yog qhov tsis zoo dua li qhov kev sib tsoo ntawm lub vibratory screen, uas tuaj yeem yog qhov tseem ceeb rau kev khaws cov khoom tawg yooj yim.
Kev ua tau zoo sib xws:Muab cov khoom lag luam txhim khu kev qha thiab zoo ib yam, txawm tias muaj cov khoom noj sib txawv.
Txhua yam -hauv-Ib qho Scrubbing thiab Sizing:Ua ke cov txheej txheem ntawm cov khoom siv txhuam / atrition thiab loj-raws li kev tshuaj ntsuam hauv ib lub tshuab.
Disadvantages ntawm Wet Trommel Screens
Kev siv dej siab:Lawv xav tau ib qho tseem ceeb thiab tsis tu ncua ntawm cov dej, uas tuaj yeem raug nqi thiab ib puag ncig nyuaj. Cov dej feem ntau yuav tsum tau rov ua dua nrog lub pas dej los yog cov thickener.
High Fine/Liquid Waste:Ua ib lub ntim loj ntawm slurry (cov dej khib nyiab nrog cov khib nyiab zoo) uas yuav tsum tau siv cov khoom siv dewatering thiab pov tseg.
Kev soj ntsuam qis dua:Piv nrog rau siab -cov ntxaij vab tshaus vibrating ceev, trommels muaj qhov qis dua ntawm ib chav tsev ntawm qhov screen thiab tuaj yeem ua tau tsawg dua qhov sib cais me me.
Loj Hneev Taw:Lawv yog lub cev ntev tshuab thiab xav tau qhov chaw ntau dua li cov ntxaij vab tshaus vibrating.
Tus nqi siab dua:Feem ntau, lub vijtsam trommel yog kim dua los yuav thiab nruab dua li lub vijtsam vibrating ntawm lub peev xwm zoo sib xws.
