I-decanter yezigaba ezibini ithelekiswa njani ne-decanter yezigaba ezintathu ngokubhekiselele ekusebenzeni kakuhle kokwahlulwahlulwa?
Intshayelelo:
Xa kufikwa kwiinkqubo zokwahlulwa kwemizi-mveliso, ii-decanters zizixhobo ezibalulekileyo zokwahlula izigaba ezahlukeneyo zomxube. Ezibini zezona zisetyenziswa kakhulu yi-decanter enezigaba ezimbini kunye ne-decanter enezigaba ezintathu. Zombini ezi matshini zenzelwe ukwahlula amasuntswana aqinileyo kulwelo, kodwa zisebenza ngeendlela ezahlukeneyo kancinci. Kweli nqaku, siza kuthelekisa i-decanter enezigaba ezimbini kunye ne-decanter enezigaba ezintathu ngokubhekiselele ekusebenzeni kakuhle kokwahlulwa, size sixoxe ngeengenelo kunye nokungalungi kwento nganye.
Imigaqo esisiseko ye-decanter enezigaba ezimbini
I-decanter enamanqanaba amabini, njengoko igama lisitsho, yenzelwe ukwahlula umxube ube ziinqanaba ezimbini ezahlukeneyo - isigaba solwelo kunye nesigaba esiqinileyo. Umgaqo osisiseko osemva kokusebenza kwe-decanter enamanqanaba amabini ngumahluko kubuninzi phakathi kwamasuntswana aqinileyo kunye nolwelo. Xa umxube ufakwa kwi-decanter, amasuntswana aqinileyo ahlala ezantsi komatshini ngelixa ulwelo luhlala phezulu. La manqanaba mabini emva koko akhutshwa ngokwahlukeneyo, apho izinto eziqinileyo zisuswa ngenye indlela yokukhupha kunye nolwelo ngenye.
Enye yezinto eziphambili ezichaphazela ukusebenza kakuhle kokwahlulwa kwesixhobo sokucola esinezigaba ezibini sisantya apho umxube ufakwa khona kumatshini. Ukuba izinga lokutya liphezulu kakhulu, izinto eziqinileyo zisenokungabi naxesha laneleyo lokuzinza ngokufanelekileyo, nto leyo ebangela ukuba inkqubo yokwahlulwa ingasebenzi kakuhle. Kwelinye icala, ukuba izinga lokutya liphantsi kakhulu, isixhobo sokucola sisenokungasebenzi ngokupheleleyo, nto leyo enokuchaphazela nokusebenza kakuhle kokwahlulwa.
Uyilo lwe-decanter enamanqanaba amabini lukwadlala indima ebalulekileyo ekusebenzeni kakuhle kwayo kokwahlukanisa. I-engile ye-conveyor, ubude besitya esisilinda, kunye nesantya sokujikeleza zonke ezi zinto zinokuchaphazela ukusebenza kwe-decanter. Ngokubanzi, i-decanter eyilwe kakuhle enamanqanaba amabini inokufikelela ekusebenzeni kakuhle kokwahlukanisa uluhlu olubanzi lwemixube eqinileyo nolwelo.
Imigaqo esisiseko ye-decanter enamaqanaba amathathu
Ngokungafaniyo nesixhobo sokucofa esinamanqanaba amabini, isixhobo sokucofa esinamanqanaba amathathu senzelwe ukwahlula umxube ube zizigaba ezintathu ezahlukeneyo - isigaba solwelo, isigaba esiqinileyo, kunye nesigaba solwelo esinomxube owahlukileyo. Ukusebenza kwesixhobo sokucofa esinamanqanaba amathathu kufana nokwesixhobo sokucofa esinamanqanaba amabini, kongezwa isigaba sokwahlulwa kwesigaba esongezelelweyo.
Kwi-decanter enezigaba ezintathu, amasuntswana aqinileyo ahlala ezantsi komatshini njengakwi-decanter enezigaba ezimbini. Nangona kunjalo, kwi-decanter enezigaba ezintathu, kukho isigaba esongezelelweyo solwelo phezulu, esiqulethe ulwakhiwo olwahlukileyo kwisigaba esiphambili solwelo. Esi sigaba solwelo esongezelelweyo sahlulwe kwisigaba esiphambili solwelo kusetyenziswa uthotho lwee-weirs zangaphakathi kunye nee-baffles ngaphakathi kwi-decanter.
Umahluko ophambili phakathi kwe-decanter enezigaba ezibini kunye ne-decanter enezigaba ezintathu bubunzima benkqubo yokwahlulahlula. Nangona i-decanter enezigaba ezibini yenzelwe ukwahlula umxube ube ziizigaba ezibini ezilula, i-decanter enezigaba ezintathu iyakwazi ukwahlula imixube enezigaba ezininzi zolwelo. Oku kwenza ii-decanters ezinezigaba ezintathu zibe nobuchule ngakumbi kwaye zifaneleke kuluhlu olubanzi lwezicelo zoshishino.
Uthelekiso lokusebenza kakuhle kokwahlulwahlulwa
Xa kuthelekiswa ukusebenza kakuhle kokwahlulwa kwezixhobo zokukhupha amanzi ezinezigaba ezibini kunye nezigaba ezintathu, kukho izinto ezininzi ekufuneka ziqwalaselwe. Omnye womahluko ophambili phakathi kweentlobo ezimbini zezi zixhobo zokukhupha amanzi bubunzima benkqubo yokwahlulwa. Nangona isixhobo sokukhupha amanzi esinezigaba ezibini senzelwe ukuphatha imixube elula, isixhobo sokukhupha amanzi esinezigaba ezintathu siyakwazi ukwahlula imixube enzima ngakumbi enezigaba ezininzi zolwelo.
