Lub Tshuab Sib Cais Tam Sim No Eddy feem ntau muaj lub nruas sib nqus tas mus li thiab lub tshuab thauj khoom (xws li siv txoj siv sia, lub nruas tsav, thiab lub cev muaj zog txo qis). Nws feem ntau yog siv rau kev cais thiab rov qab tau ntau yam hlau tsis yog hlau xws li tooj liab thiab txhuas los ntawm cov khib nyiab khov kho hauv kev lag luam xws li cov khib nyiab hluav taws xob, cov qhov rai yas qub thiab cov qhov rooj, thiab cov tsheb seem. Lub tshuab sib cais no ua rau muaj kev ua haujlwm ntau ntxiv, txo kev siv zog ua haujlwm, thiab ua tiav kev cais tawm ntau dua 98%.
Lub tshuab cais tam sim no eddy muaj lub tshuab tseem ceeb, lub vibratory feeder, thiab lub zog tswj hwm.
Kev sib cais tam sim no eddy yog ib txoj kev siv tshuab cais raws li cov khoom sib txawv conductivities. Nws siv ob qho tseem ceeb ntawm lub cev: lub zog sib nqus hloov pauv ua rau muaj lub zog hluav taws xob hloov pauv (electromagnetic induction), thiab cov conductors nqa tam sim no tsim lub zog sib nqus (Biot-Savart txoj cai).
Thaum lub sijhawm ua haujlwm, lub tshuab cais tawm tsim cov teb sib nqus hloov pauv siab ntawm qhov chaw ntawm lub tshuab cais tawm. Thaum cov hlau uas tsis yog hlau hla dhau qhov teb no, lawv ua rau muaj cov hluav taws xob eddy. Cov hluav taws xob no tsim cov teb sib nqus tawm tsam qhov teb qub, ua rau cov hlau (xws li tooj liab thiab txhuas) dhia mus tom ntej vim yog kev sib nqus repulsion, ua rau lawv sib cais ntawm cov khoom tsis yog hlau.
Cov ntawv thov muaj xws li:
- Cov chaw zom hlau pov tseg: Cais cov hlau uas tsis yog hlau los ntawm cov hlau pov tseg.
- Kev rhuav tshem thiab tsoo cov nroj tsuag tsis siv neeg: Kev cais cov hlau uas tsis yog ferrous los ntawm cov khoom tawg.
- Cov chaw siv cov khib nyiab hluav taws xob rov ua dua tshiab: Rov qab tau cov hlau los ntawm cov khoom seem ntawm lub voj voog hluav taws xob.
- Kev lag luam rov ua dua iav: Tshem tawm cov hau txhuas thiab cov txhuas lossis cov hlau tooj liab ntawm cov khoom siv iav uas raug tsoo.
- Kev cais cov khib nyiab hauv tsev ua ntej: Cais cov kaus poom txhuas, cov hau, thiab cov tooj liab thiab cov hlau txhuas ntawm cov khib nyiab hauv tsev.
- Kev siv cov khib nyiab hauv tsev rov qab los ntawm kev hlawv cov khib nyiab: Cais cov hlau uas tsis yog hlau tawm ntawm cov khib nyiab hlawv.
- Kev lag luam rov ua dua daim ntawv: Kev cais cov hlau uas tsis yog hlau los ntawm cov ntawv seem.
- Cov chaw zom cov qhov rooj thiab qhov rai thiab cov chaw zom cov qauv txhuas: Cais cov txhuas thiab lwm yam hlau ntawm cov ntaub ntawv.
- Lwm lub sijhawm: Cais lwm cov hlau uas tsis yog hlau ntawm cov khoom tsis yog hlau.
Lub tshuab cais hluav taws xob eddy uas huate tsim tau siv ib qho kev teeb tsa tshwj xeeb ntawm tib lub ncej ob kab thiab kev teeb tsa staggered, ua kom lub zog magnetic field siab tshaj plaws thiab lub zog eddy tam sim no siab tshaj plaws. Qhov kev tsim no ua rau kev sib cais hlau zoo dua thiab cov nqi rov ua dua tshiab.
Cov yam ntxwv tseem ceeb:
- Kev ua haujlwm yooj yim rau kev sib cais hlau / tsis yog hlau.
- Kev teeb tsa yooj yim, sib xws nrog cov kab ntau lawm tshiab lossis uas twb muaj lawm.
- Lub zog sib nqus siab txog li 3000-3500 Gauss, ob npaug ntawm cov nqi rov qab piv rau cov qauv sib cais.
- Kev hloov kho yooj yim rau kev ua tau zoo heev.
- Kev siv hluav taws xob tsawg thiab tus phooj ywg ib puag ncig.
- Muaj peev xwm cais cov ntaub ntawv ntawm ntau qhov ntau thiab tsawg raws li kev tig ntawm lub log.
Tam sim no, huate's eddy tam sim no separators yog dav siv hauv tsev thiab xa tawm mus rau ntau tshaj kaum ob lub tebchaws thiab thaj chaw, khwv tau txais kev qhuas los ntawm ntau tus neeg siv khoom thoob ntiaj teb.
