Ekupheleni kwekhulu le-19, kwaba nothisha wesikole samabanga aphansi waseMelika ogama lakhe linguKelly Abbarsser. Umyeni wakhe wayengumshini wokulungiswa kwemishini emayini. Ngolunye usuku, umyeni wakhe wabuyisa i-chalcorforyrite ethile. Wayefuna ukuba ahlanze isikhwama esinamafutha asebenzise enye injongo. Uthole ukuthi ngesikhathi senqubo yokuhlanza, izinhlayiya ezincane ze-chalcopyrite zinganamathela kuma-bubbles wensipho futhi zintanta emanzini, ngenkathi inhlabathi ingena ebhakedeni. Ekugcineni, lokhu kutholwa ngengozi kwakungumsuka wobuchwepheshe obusha bokufakwa kwama-flotation kanye nokusebenza kwamaminerali.
Sekudlule iminyaka engaphezu kwekhulu, futhi ubuchwepheshe be-flotation buthuthukile ngokuqhubekayo futhi izinhlelo zalo sezindele kakhulu. Ngokusho kwezibalo, ama-90% ama-ores wensimbi angewona ama-ferrous emhlabeni okwamanje acutshungulwa yi-flotation. Ngaphezu kwalokho, i-flotation isetshenziswa kabanzi. Isetshenziselwa ukuhlunga izinsimbi ezingavamile, izinsimbi eziyigugu, izinsimbi ezinobungozi, okungezona izinsimbi, amalahle nezinye izinto zokwakha amaminerali.
Enqubweni yesimanje ye-flotation, uhlelo lokusebenza kanye nokwengezwa okunembile kwama-reagents we-flotation sekubaluleke kakhulu, ngoba ngemuva kokwelashwa ngama-reagents we-flotation, ukuguquguquka kwamaminerali kungashintshwa, ukuze amaminerali athengwe ama-bubble, ngaleyo ndlela afinyelele inhloso yokusebenza kwamaminerali.
Umlando wokuthuthuka kohlelo lokungezwa kwamaminerali agent
Ngaphambi kokusungulwa kwemibuthano ye-logic, izitshalo zokuqala ze-flotation ezisetshenziselwa ukwengezwa kwamakhemikhali. Ukuthembela ekuhlangenwe nakho komuntu siqu kwabasebenzi bezokufakelwa, ukuvulwa kwe-valve yamakhemikhali kwalungiswa ngesandla ukuze kulungiswe izinga lokugeleza kwamakhemikhali we-flotation.
Ngawo-1960s, njengoba ubuchwepheshe bezimoto buvuthiwe, unjiniyela wamanzi aseMelika u-Andros wasebenzisa u-AndrUOs wasebenzisa umgomo we-waterwheel ukusungula umshini we-scoop-hlobo dosing umshini. Ngokushintsha ivolumu nenombolo yama-scoops epuletini ye-scoop, inani lezokwelapha elingeziwe lingashintshwa. ukugeleza.
Kepha nje ukulawula ukuhamba kwamakhemikhali we-flotation ngokujikeleza akukude nokwanele. Ngemuva kweminyaka yama-1970s, i-transistor-eshunyekwe kabusha ye-transistor ehlanganisiwe (umjikelezo ohlanganisiwe) adluliswa emkhakheni wamasosha aye embonini yezempi. Ukukhiqizwa okuphezulu okuphezulu kunciphise izindleko ziye ku-1/11 zesikhathi esedlule, iCanadian Jack Johns, i-Care Mechanic kanye ne-Electronics Engathi, basebenzise isikhathi sakhe sokuphumula, basebenzise isikhathi sakhe sokuphumula sokwakha amayunithi wokugeleza ashintshile amasiginali. Emhlanganweni wokushintshaniswa kwezobuchwepheshe, i-American Fisher Technisher Taland yenkampani ye-Valve efundile mayelana nobuchwepheshe obushintshayo we-jack johns
Kulezi zinsuku, ngokuthandwa kwe-PLC ehlelekile yokulawula i-Logic (emele ama-Brand Nokia) Uhlelo olunjalo manje lungakwazi futhi ukugxila kwezimayini eziningi. Imvamisa sikubiza: umshini we-solenoid valve dosing umshini (noma umshini wokudonsa amandla adonsela phansi).
Maphakathi nawo-1980s, ubuchwepheshe bokuguqula imvamisa busetshenziselwe izimboni eziningi. Usebenzisa umgomo wokuguqula imvamisa olawulwa amaphampu we-mechanical diaphragm ungathola ukulawulwa okuphezulu kokuhamba kwemithi kunezindlela ezedlule ze-dosing (i-solenoid valve dosing imishini nemishini ye-spoon deosing). Lokhu kungasiza abaphathi bami ukuba banciphise imfucumfucu yokungcola namakhemikhali ngezinga elikhulu.
Ngemuva kweminyaka yama-1980s, amaphampu we-metering aqala ukushintshela emakethe yezimboni, ikakhulukazi emikhakheni yamakhemikhali anembile nokwelashwa kwamanzi. Kusukela ukwakhiwa koqobo kwamaphampu oku-metering kwakuwukuxazulula inkinga yokulethwa okuphindaphindwayo nokunembile koketshezi olujwayelekile, amaphampu we-metering asetshenziswe kabanzi embonini yokusebenza kwamaminerali. , ukushiyeka kwalo sekudalulwe. Izinkinga ezinkulu yilezi: 1 Lapho inani elincane lisethwe, iphutha lingaphezulu liphakeme ngo-50% noma ngaphezulu; 2. I-diaphragm ngemuva kokuqhamuka, umuthi uzovuza; 3 Enqubweni yokushintsha ngokuqhubekayo ukugeleza kwezinga lokugeleza, iphutha lokuphuma lizokwanda. I-4. I-blockage yepayipi izodala ikhanda lempompo liqhume ngaphansi kwengcindezi, futhi amakhemikhali avuthiwe azongcolisa imvelo. 5 I-6. Kunemibuthano eminingi yokulawula yangaphandle yamapayipi namapayipi, okwenza ukugcinwa nokufakwa kuyinkimbinkimbi ngokwengeziwe.
Isazi sase-Italian Giovanni Battista Venturi sathola umphumela we-Venturi usebenzisa umthetho weBernoulli Fluid bese wasungula i-Venturi Tube. Ngo-2013, uWilber wasebenzisa umgomo we-Venturi ekulethweni kwama-reagents we-flotation futhi wasungula i-VLB uhlelo lwe-CNC I-CNC Dosing System (Patent No. ZL201406492611406492611.66492611.64992611.64492611.64492611.66492611.66492611.66492611.6) isebenzisa i-diaphragm ukushayela i-diaphragm ukuze ushayele amakhemikhali. Uhlelo lwe-Dosing lulawulwa yi-Film Sway Logic Control Circuit. Yabizwa nangokuthi umshini we-hydrodynamic dosing umshini.
