intshayelelo
Kwiinjineli zoshishino, abaphathi bezityalo kunye nabathengi bokuthenga abafuna izixhobo zokwahlulahlula ulwelo oluqinileyo ezingabizi kakhulu nezisebenza kakuhle,
sieve bend isikrini Imile njengesisombululo sokuvavanya esingaguqukiyo esingenakutshintshwa. Ikwabizwa ngokuba yiDSM screen emva kweDutch State Mines eyasungula ubuchwepheshe, i-sieve bend yiphaneli yentsimbi egobileyo eyenzelwe ukuhlelwa kwe-slurry eqhutywa ngumxhuzulane, ukukhupha amanzi kunye nokubuyiselwa kwezinto eziqinileyo ezincinci ngaphandle kweemoto, ukungcangcazela okanye ukusetyenziswa kwamandla. Ngokungafaniyo nezikrini ezingcangcazelayo ezixhomekeke kumandla oomatshini, iiyunithi ze-sieve bend zisebenzisa amandla ombane endalo kunye ne-Coanda effect ukubonelela ngemveliso ezinzileyo, ukugcinwa okuncinci kunye nobomi benkonzo ende kuzo zonke izimbiwa, amanzi amdaka, ukucubungula ukutya kunye namashishini e-pulp. Esi sikhokelo sigubungela umgaqo waso wokusebenza, iingenelo eziphambili, usetyenziso oluphambili lwemizi-mveliso, iinkcukacha ezenziwe ngokwezifiso kunye neengcebiso eziphambili zokukhetha ukunceda abathengi bemizi-mveliso bakhethe i-sieve bend efanelekileyo kwimigca yabo yemveliso.
Indlela i-Sieve Bend Screen esebenza ngayo
Isakhiwo esiphambili se-sieve bend eqhelekileyo siquka isikrini se-wedge wedge esigobileyo esigobileyo, isakhelo sokuxhasa esomeleleyo kunye nesitya sokusasaza ukutya. Iintambo ze-V ezimile okwe-wedge zidityaniswa ngendlela ethe nkqo ukuya ekuhambeni kodaka, zenza iindawo ezincinci eziphezulu kunye nezikhewu ezibanzi ezithintela ukuvaleka kwamasuntswana. Xa udaka luhamba ngokulinganayo kumphezulu ogobileyo kwi-engile elawulwayo ye-45°–90°, amandla amabini okwahlula asebenza ngaxeshanye.
Okokuqala, amandla adonsela amanzi kunye namasuntswana amancinci kakhulu ngokusebenzisa izithuba zentambo ye-wedge. Okwesibini, umphezulu ogobileyo uvelisa isiphumo seCoanda, esinqumla umaleko omncinci wolwelo oluvela kumjelo we-slurry ngoko nangoko. Amasuntswana amakhulu aqinileyo atyibilika ecaleni kwe-arc yesikrini aze aphume kwi-outlet esezantsi, ngelixa amanzi ahluziweyo ehamba ngezithuba ukuya kwi-tank yokuqokelela engezantsi. Uphawu lobuchwephesha olukhethekileyo yindawo yawo yokusika: ubungakanani bokwahlulwa kwamasuntswana obuphantse bube sisiqingatha sobubanzi besithuba somzimba, okuvumela ukuvavanywa okucokisekileyo okuncinci kungenzeki kwizikrini ezisicaba. Ekubeni kungekho zindawo zishukumayo, yonke inkqubo isebenza ngokuthula nangokuqhubekayo ngaphandle kokufakwa kwamandla.
Iingenelo eziphambili zeWedge Wire Sieve Bend Screens
- Akukho kusetyenziswa kwamandla kunye neendleko zokusebenza eziphantsi
Njengesixhobo esingashukumiyo ngokupheleleyo, ii-seeving zokugoba azidingi mbane, iibhanti okanye ii-vibrators. Iifektri zisusa iindleko zamandla zemihla ngemihla kunye neendleko zokutshintshwa kwezixhobo ezingasetyenziswanga zeemoto, nto leyo enciphisa kakhulu uhlahlo-lwabiwo mali lokusebenza lwexesha elide xa kuthelekiswa noomatshini bokuhlola abatshintshayo.
- Uyilo Lokuzicoca Oluchasene Nokuxinana
Izithuba ezikhula ngokukhawuleza phantsi kocingo lwe-wedge zithintela ukufiphala kwamasuntswana, nokuba kusetyenzwa i-sticky pulp, amanzi amdaka efayibha okanye udaka lweminerali. Ukuhamba kodaka rhoqo kukhupha izinto eziqinileyo ezishiyekileyo ngokuzenzekelayo, kunciphisa ixesha lokungasebenzi kokucoca ngesandla ngaphezulu kwama-60%.
- Ubungakanani obuphezulu kunye neNyathelo eNcinci
Igoba lesihluzo elinye liphatha ukuya kuthi ga kwiilitha ezili-122 ze-slurry ngomzuzwana ngemitha yesikwere, kunye nomthamo wokucubungula ophindwe kalishumi kunezikrini zentambo ezisicaba ezinobukhulu obufanayo. Uyilo lwayo olugobileyo oluphantsi luhambelana neendawo zokuhlamba iimpahla ezincinci, izitishi zokumpompa kunye neetanki zokucoca kwangaphambili ezinegumbi elincinci.
- Ukumelana nokugqwala kunye nokukrala
Iingqiniba zesihluzo ezenziwe ngokwezifiso zisebenzisa i-SS304, SS316L okanye i-Duplex 2205 yentsimbi engagqwaliyo yamanzi amdaka kunye ne-mineral slurry. Iiphaneli ezigqunywe nge-polyurethane ziyafumaneka kwi-ore yemigodi erhabaxa kakhulu, nto leyo eyandisa ubomi benkonzo ukuya kwiminyaka eli-10 nangaphezulu phantsi kweemeko zokusebenza ezinzima.
- ULungiselelo oluchanekileyo
Abavelisi balungiselela ii-arc engile, iindawo zokuvula (ii-microns ezingama-50 ukuya kwi-12mm), ububanzi besikrini kunye nobukhulu besakhelo ukuze zihambelane neendawo ezithile zokusika, amazinga okutya kunye noxinzelelo oluqinileyo, okuxhasa ukufakwa kweplagi kunye nokudlala kwimigca yemveliso ekhoyo.
Izicelo Ezibanzi Zemizi-mveliso zeSieve Bend
1. Ukulungiswa kwemigodi kunye namalahle
Le yeyona ndlela ivuthiweyo yokusebenzisa izikrini zokugoba kwesihluzo. Iimigodi ziyisebenzisela ukususa uthuli, ukususa amanzi ngaphambi kokuba kukhutshwe amanzi kunye nokususa inkunkuma erhabaxa ngaphambi kokuba kubekho iinkanyamba kunye neeseli zokudada. Izityalo zokuhlamba amalahle zixhomekeke kwiisihluzo ezigobileyo ukuze zahlule amasuntswana amalahle kumanzi amdaka, zinciphisa ukuguguleka kwepompo esezantsi ngama-30-40% kwaye ziphucula amazinga okubuyisa izimbiwa. Imigca yokucubungula igolide, ubhedu kunye ne-iron ore isebenzisa kakhulu iisihluzo ezimileyo ukuze kuzinziswe uxinano lwe-slurry.
2. Unyango lwamanzi amdaka kaMasipala kunye nooShishino
Njengendlela yokuqala yokukhusela ngaphambi konyango, ii-sieve bends zihluza izinto eziqinileyo ezixhonyiweyo, imicu, iintsalela zokutya kunye nenkunkuma yeplastiki evela kwilindle, ukungcola kwempahla kunye namanzi amdaka eekhemikhali. Ukususa amasuntswana amakhulu kwangaphambili kunciphisa umthwalo kwi-MBR, DAF kunye neetanki zebhayoloji, kunciphisa ukusetyenziswa kweekhemikhali kunye neendleko zonyango lwelindle kwizityalo zamanzi.
3. Ukutya, Iziselo kunye nokuLungiswa kwesitatshi
Iifektri zesitatshi, iswekile, ibhiya kunye nemveliso yeziqhamo zisebenzisa ii-stainless steel seevings ukuze zisuse amanzi asetyenzisiweyo kwiinkozo, zahlukanise iintsalela zepulp kwaye zibuyisele amanzi asetyenziswa kwakhona. Umphezulu wentambo egudileyo uthintela ukonakalisa amasuntswana okutya athambileyo, uxhasa imigangatho yococeko yokutya ngaphandle kweengozi zongcoliseko.
4. Ushishino lwePulp kunye nePhepha
Iifektri zephepha zisebenzisa iindlela zokusila ukuze zibambe ifayibha emanzini amhlophe, ziphinde zisebenzise izinto ezixabisekileyo zepulp kwaye zinciphise inkunkuma yezinto eziluhlaza. Zikwahluza amanzi amdaka enziwe ngephepha ukuze zinciphise ifayibha ekhutshwa kwiinkqubo zokungcola, zihlangabezana nemigaqo yokukhupha inkunkuma kwindawo engqongileyo.
5. Iinkqubo zezoLimo kunye nokuNcedisa
Imijelo yokunkcenkceshela yasefama ifaka ii-seeve bends ezifana nebhokisi ukuvala inkunkuma, i-algae kunye nenkunkuma yezityalo, ikhusela imibhobho yokunkcenkceshela ngamaconsi kunye neempompo zamanzi ekuvalekeni.
Iingcebiso Zokuthenga Izikrini Zesihluzo Esilungiselelweyo
Abathengi bemizi-mveliso kufuneka baqinisekise iiparameter ezintathu eziphambili ngaphambi koku-odola: indawo yokwahlulahlula efunekayo ukuchaza ubungakanani besloti, umthamo ophezulu wokutya okuludaka ukuze kubalwe ububanzi besikrini, kunye nokubola okuphakathi ukuze kukhethwe amanqanaba entsimbi engatyiwayo. Ii-engile ze-arc (45°, 60°, 90°) zikhethwa ngokusekelwe kumxholo oqinileyo we-slurry—uxinzelelo oluphezulu oluqinileyo lufuna ii-engile ezinkulu ze-arc ukuze kukhutshwe amanzi ngokupheleleyo. Ababoneleli abaninzi banikezela ngeeyunithi ze-hydro sieve ezipheleleyo ezidibanisa iiphaneli ze-sieve bend kunye neefreyimu zentsimbi, iibhokisi zokutya kunye nee-taw zokuqokelela ukuze kufakwe ngqo ngaphandle komsebenzi owongezelelweyo wokuhlanganisa.
isiphelo
Kwixesha apho iifektri zibeka phambili ukonga amandla, ukugcinwa okuphantsi kunye nemveliso ezinzileyo, izikrini zokugoba kwesihluzo zihlala zisisombululo sokwahlula esingaguqukiyo esingabizi kakhulu esingenakuthelekiswa nezikrini ezingcangcazelayo kunye nezihluzi ezijikelezayo. Ukusebenza kwazo okungenamandla, ulwakhiwo lwazo oluchasene nokuvaleka kunye nokwenza ngokwezifiso okuguquguqukayo kuhambelana phantse nazo zonke iimeko zokwahlulahlula ulwelo oluqinileyo ukusuka ekumbiweni okunzima ukuya ekulungisweni kwamanzi amdaka okutya. Nokuba ufuna iiphaneli zokugoba zesihluzo se-wedge wire okanye iiyunithi zokuhlola isihluzo se-hydro ezipheleleyo, ukukhetha umenzi onokunyamezelana okuchanekileyo kwesloti kunye nokuwelda okuhlala ixesha elide kuqinisekisa ukusebenza kokwahlukana okuhlala ixesha elide kwaye kwandisa imbuyekezo yakho yemveliso kutyalo-mali.
