Kodi mukuvutitsidwa ndi madzi ochulukirapo mumadzi ocheperako komanso zolimba pakusefukira? Kodi mukufuna kukhathamiritsa ntchito ya thickener pochotsa muyeso wobwerezabwereza komanso zolakwika za anthu? Ogwiritsa ntchito ambiri amakumana ndi mavuto omwewo m'makampani opangira mchere kuti apulumutse madzi ndikusonkhanitsa zinthu zamtengo wapatali zokonzedwa. Real-time density mita imagwira ntchito bwino pokwaniritsa zolingazi.
Nkhani yotsatirayi ikugogomezera kufotokoza zolinga ndi ubwino wa kachulukidwe kachulukidwe pamagulu osiyanasiyana a matanki okhuthala. Tiyeni tiyambe ndi kufotokoza mwachidule kwa ndondomeko ya makulidwe, ndikutsatiridwa ndi zifukwa zisanu zoyezera kachulukidwe mu ndondomeko yolekanitsa.
Kodi Thickening ndi Ntchito Yanji?
Kukhuthala kumaphatikizapo kulekanitsa chisakanizo chamadzimadzi cholimba kuti chikhale chochepa kwambiri komanso kusefukira momveka bwino. Zakale zimakhala ndi tinthu tating'ono tolimba ndipo zotsirizirazo sizimaphatikizapo zonyansa momwe zingathere. Njira yolekanitsa ndi zotsatira za mphamvu yokoka. Tinthu tating'onoting'ono tosiyanasiyana tosiyanasiyana timapanga zigawo zosiyanasiyana kudzera mu thanki.
Njira zokometsera zimachitika mu thanki ya sedimentation mu mineral processing kuti apatutse ma concentrates ndi matailing.
Zoyezera Zofunika Pakukhuthala
Online liquid density mitaamafunikira kuti muwongolere magwiridwe antchito a thickeners. Mwachitsanzo, malo oyikapo amaphatikizapo chakudya, kusefukira, kusefukira ndi mkati mwa thanki ya thickener. M'mikhalidwe yapamwamba, masensa awa amatha kutengedwa ngatislurry kachulukidwe mitakapenasludge kachulukidwe mita. Zimathandizanso pakuwongolera kuyendetsa bwino kwa ma drive, mapampu komanso kuwongolera bwino kwa ma flocculants.
Zifukwa Zoyezera Kachulukidwe
Zifukwa zoyezera kachulukidwe zitha kukhala zosiyana. Mikhalidwe isanu yotsatirayi ikuwonetsa kufunikira kowunika kachulukidwe kachulukidwe kuti mafakitale akwaniritse bwino.
No. 1 Kubwezeretsa Madzi
Madzi amatengedwa kuti ndi chimodzi mwazinthu zofunika kwambiri pamakampani amigodi ndi mchere. Chifukwa chake, kubweza madzi kapena kugwiritsanso ntchito madzi kumapulumutsa mtengo wokhuthala kwambiri. Kukula pang'ono kwa 1-2% mu kachulukidwe kakang'ono ka kusefukira kumatanthauza madzi ochulukirapo ofunikira pakukhazikitsa. Kuwonjezeka kwa kachulukidwe kumagwira ntchito potsimikizira kulimba kwa madamu akutsanza, omwe amatha kugwa ngati pali madzi ochulukirapo omwe amapopa madamu.
No. 2 Mineral Recovery
Mu concentrate thickeners, chakudya nthawi zambiri chimachokera ku flotation circuit. Kuyandama kumaphatikizapo kulekanitsa tinthu ting'onoting'ono pogwiritsa ntchito mphamvu yokoka. Mwa kuyankhula kwina, omwe ali ndi mpweya wophatikizidwa amakwera pamwamba ndikuchotsedwa, pamene ena amakhalabe mumadzimadzi. Izi zikachitika muzowonjezera zinthu, thovu limatha kunyamula zolimba ndikusefukira.
Zolimba izi ndi zamtengo wapatali ndipo, ngati sizinabwezeretsedwe, zimatha kuchepetsa kuchira kwathunthu kwachitsulo chokhazikika. Kuphatikiza apo, zolimba pakusefukira zimatha kubweretsa mtengo wokwera wa reagent, kuwonongeka kwa mapampu ndi mavavu, ndikuwonjezera ndalama zolipirira, monga kuyeretsa matanki amadzi pamene zolimba zimawunjikana pamenepo.
Pafupifupi 90% ya zolimba zomwe zidatayika pakusefukira zimatha kubwezeredwa pakapita nthawi (mwachitsanzo, m'matanki ndi madamu). Komabe, 10% yotsala, yomwe imayimira phindu lalikulu lazachuma, imatayika kosatha. Kuchepetsa kutayika kwa zolimba pakusefukira kuyenera kukhala kofunikira. Kuyika ndalama m'matekinoloje owongolera njira kumatha kukulitsa mitengo yobwezeretsa ndikubweza mwachangu pazachuma.
Kugwiritsa ntchito Lonnmeterkachulukidwe mitandimita yothamangamu underflow kumathandiza kuwunika bwino ntchito thickener. Kuzindikira nthawi yeniyeni ya zolimba mu kusefukira kumathekanso ndi kachulukidwe kapena zolimba mita. Zizindikiro za 4-20mA za zida zitha kuphatikizidwa mumayendedwe owongolera kuti azitha kukhathamiritsa mwachindunji.
3 Kugwiritsa Ntchito Flocculant Moyenera
Ma Flocculants amagwira ntchito popititsa patsogolo kusungunuka kwa dothi, komwe ndi mankhwala omwe amathandizira kuti tinthu tating'onoting'ono tazamadzi timene tiwungana. The dosing wa flocculants kuganizira mtengo kulamulira reagent ndi ntchito bwino. Kachulukidwe mita imalola kuwongolera kachulukidwe kolondola komanso kodalirika kwa chakudya cha thickener. Cholinga ndi kukwaniritsa apamwamba zotheka zolimba kuchuluka ndi kulemera mu chakudya slurry pamene kulola ufulu tinthu yokhazikika. Ngati kachulukidwe ka slurry wa chakudya ukuposa chandamale, payenera kuwonjezeredwa zakumwa zoledzeretsa, ndipo mphamvu zambiri zosakaniza zitha kufunikira kuti chakudya chisakanizidwe bwino.
Kuyeza kachulukidwe ka nthawi yeniyeni kwa slurry ya chakudya pogwiritsa ntchito mita ya inline density mita ndikofunikira pakuwongolera njira. Izi zimatsimikizira kugwiritsa ntchito bwino kwa flocculant ndikuwongolera njira yosakanikirana, kupangitsa kuti thickener igwire ntchito mkati mwake.
4 Kuzindikira Mwamsanga Mavuto a Flocculation
Othandizira amayesetsa kuti zinthu zizikhala zokhazikika muzokhuthala, kukwaniritsa kusefukira komveka bwino kokhala ndi zolimba zochepa komanso kusefukira kwamadzi pang'ono. Komabe, zinthu zomwe zimapangidwira zimatha kusintha pakapita nthawi, zomwe zimapangitsa kuti pakhale kusakhazikika bwino, kuchepa kwa madzi osefukira, komanso zolimba pakusefukira. Mavutowa amatha chifukwa cha kuyandama, mpweya kapena thovu mu thanki, kapena kuchuluka kwa zolimba kwambiri muzakudya.
Kugwiritsa ntchito zida ndi makina odzipangira okha kungathandize ogwiritsa ntchito kuwongolera pozindikira zinthu ngati izi munthawi yeniyeni. Kupitilira muyeso wapaintaneti, zida zotengera thanki ngati ma ultrasonic bed level probes zitha kupereka chidziwitso chofunikira. Zofufuza za "zosambira" izi zimayenda m'mwamba ndi pansi mkati mwa thanki, kuwonetsa matope, malo okhazikika, komanso kumveka bwino. Miyezo ya bedi ndiyothandiza kwambiri pakuwongolera njira zowongolera, kuwonetsetsa kuti magwiridwe antchito azigwira.
Slurry Density Meter (SDM)
The Slurry Density Meter (SDM) ndi njira yothandiza zachilengedwe kutengera ma metres achikhalidwe cha nyukiliya. Yadziwika kwambiri, ndikuyika mazana ambiri padziko lonse lapansi. SDM imapereka miyeso yolondola komanso yodalirika ya kachulukidwe, ndikupangitsa kuti ikhale yankho labwino kwa mafakitale amakono opanga mchere.
Kuyeza kachulukidwe kumagwira ntchito yofunika kwambiri pakuwongolera magwiridwe antchito a thickener ndipo kumakhala ngati chizindikiro chofunikira pakuwongolera njira. Potengera matekinoloje apamwamba oyezera ndi njira zowongolera, ogwiritsira ntchito amatha kukulitsa magwiridwe antchito, kukulitsa mitengo yobwezeretsa, ndikuchepetsa mtengo wogwirira ntchito.
