Amaminerali angewona azibuthe aphonswa ebhokisini lemisila ngaphansi kwesenzo samandla angenawo amandla okunyakaza namandla adonsela phansi, ukuze kufezwe injongo yokuhlunga. Umgomo wokusebenza we-CXFG uchungechunge lokumisa isihlukanisi kazibuthe uboniswa kuMfanekiso 13.
Umfanekiso 13 Umgomo wokusebenza we-CXFG uchungechunge lokumisa isihlukanisi kazibuthe
Amaphuzu obuchwepheshe besakhiwo
Amaphoyinti wobuchwepheshe we-CXFG yochungechunge lokumiswa kwesihlukanisi kazibuthe:①Ukusebenzisa indwangu yohlobo lwe-counter-roller akukwazi kuphela ukuqinisekisa ukufana komthamo wokucubungula kanye nesendlalelo sezinto ezibonakalayo, kodwa futhi kunganqanda kuphinde kusize ukuchotshozwa kwensimbi enkulu yokusanhlamvu. Kukhona igebe elithile phakathi kwamapheya amabili ama-roller. Ipheya lamagiya ahlanganayo ashayelwa ukuze azungezise ngokuhambisanayo nangokuhlehla ngenjini yokunciphisa imvamisa. Umsebenzisi angakwazi ukulungisa isivinini samarola ngokuya ngokuphumayo ukuze alungise inani lensimbi.②Ibhande elihlukanisayo eliyinhloko lamukela uhlelo oluvulekile lukazibuthe olunepulani, elinezigxobo kazibuthe eziningi ezihlelwa ngokushintshana. I-planar magnetic system inendawo yokuhlukanisa isikhathi eside kanye nesikhathi eside sokudonsa, okudala amathuba amaningi okukhangisa kwe-ore kazibuthe. Futhi ngenxa yokuthi isimiso sikazibuthe siyingxenye engenhla yensimbi, insimbi kazibuthe Endaweni yokuhlunga, isesimweni esimisiwe futhi esixegayo, i-monomer i-adsorbed, ayikho into efakiwe, kanye nokusebenza kahle kokuthuthukisa izinga ephakeme kakhulu kunaleyo yesistimu kazibuthe egobile.Amaminerali kazibuthe ahamba eduze kwezigxobo kazibuthe futhi adlule ohlelweni lukazibuthe lwendiza. Amaminerali kazibuthe aphendulwa ngokuzenzakalelayo izikhathi eziningi. Imvamisa yokuphenduka inkulu futhi isikhathi side, okuzuzisa ukuthuthukisa izinga lamaminerali kazibuthe.Kuhlelo lukazibuthe olucwathile, umklamo unomehluko kazibuthe ohlakaniphile nonengqondo, futhi amaminerali ahlala engaphansi kwesenzo se-multi- izigxobo ze-polar magnetic, ezihlukanisa ngempumelelo i-ganggue kanye namaminerali angewona kazibuthe, ngaleyo ndlela athole ukululama okuphelele, athuthukise izinga lokugxilisa ingqondo futhi anciphise umgijimi we-Tail. hlukanisa izinhlayiya ezincane. I-roller ithatha isakhiwo se-groove ukuvimbela ukuchezuka kwebhande.
Uchungechunge olubalulwe ngenhla lwemikhiqizo ekhiqizwe yi-Shandong Huate Magnetoelectric Technology Co., Ltd. lufanele ukuhlukaniswa kwamaminerali osayizi bezinhlayiyana ezahlukene. Zinokugxila kwazo ekwakhiweni kwesakhiwo somkhiqizo ukuze kuhlangatshezwane nezidingo zezinkomba zokuhlunga ezihlukene, futhi zisetshenziswe ngempumelelo. Emabhizinisini amaningi ezimayini, ibambe iqhaza elihle ekongeni amandla kanye nokunciphisa ukusetshenziswa kanye nokwenza ngcono ukusebenza kahle.
Amabhizinisi ezimayini kufanele akhethe umshini wokuhlukanisa uzibuthe ofanele izimo zebhizinisi lawo ngokwesimo sensimbi kanye nezimo zobuchwepheshe ukuze kuthuthukiswe ukusebenza kahle kokukhiqiza.
Abakhiqizi bezinto zokusebenza kufanele baqhubeke bethuthukisa futhi baphelelise ukusebenza kwemikhiqizo yabo ngokwezidingo zokukhiqizwa kwamabhizinisi ezimayini, baxazulule izinkinga ezithile lapho besetshenziswa, bakhiqize imikhiqizo efaneleke kakhulu ezimbonini, futhi bakhuthaze ukuthuthukiswa kobuchwepheshe bemishini yokuhlukanisa kazibuthe.
