Iyini i-Slurry Thickener Tank? Indlela Yokuhlukanisa Okunguketshezi Nokuqinile
Ithangi lokujiya i-slurry iyunithi yezimboni eklanyelwe ukukhulisa ukugxila kwezinto eziqinile ku-suspension ewuketshezi oluqinile ngokusebenzisa inqubo yokuhlala ngenxa yamandla adonsela phansi. Inhloso yayo eyinhloko ukuhlukanisa i-slurry encane, ehlanjululwe ibe "underflow" eminyene (izinto eziqinile ezigxilile) kanye ne-"overflow" ecacile (uketshezi).
Emikhakheni ehlukahlukene kusukela ezimayini nasezinsimbi kuya ekuhlanzeni amanzi angcolile emadolobheni, ithangi lokujiya lisebenza njengesigaba esibalulekile sokukhipha amanzi. Ngokususa amanzi amaningi ku-slurry, kunciphisa kakhulu umthamo wezinto ezidinga ukuthuthwa, ukugcinwa, noma ukucutshungulwa, kuyilapho kutholakala amanzi enqubo abalulekile ukuze asetshenziswe futhi.
Ukusebenza Kwayo: Indlela Yokuhlala
Ukusebenza kwejiya kuncike ekuziphatheni kwemvelo kwezinhlayiya lapho zihlala. Lapho i-slurry ingena ethangini, ijubane loketshezi liyancipha, okuvumela amandla adonsela phansi ukuba anqobe amandla okuntanta namandla okudonsa, okubangela ukuthi izinhlayiya zicwilise phansi.
1. I-Feedwell
Inqubo iqala endaweni yokondla (etholakala maphakathi nendawo phezulu). Yilapho ukungena kwe-slurry okungenayo. Indawo yokondla yakhelwe ukususa amandla e-kinetic okuphakelayo, iqinisekisa ukuthi i-slurry ingena ethangini elikhulu ngobumnene ukuvimbela ukuphazamiseka, okungaphazamisa inqubo yokuhlala.
2. Indawo Yokuhlala
Emzimbeni omkhulu wethangi, izinto eziqinileyo ziqala ukwakha "umugqa wodaka." Uketshezi olucacile lukhuphuka luye phezulu bese luphuma phezu kwe-overflow weir.
3. Umshini Wokukhuhla
Ukuze kube lula ukususwa kwezinto eziqinile eziwugqinsi ezansi, kusetshenziswa umshini wokukhuhla ozungezayo onamandla. Lawa makhuhla azungeza kancane, ephusha kancane izinto eziqinile ezihleliwe ziye endaweni yokukhipha emaphakathi. Lesi senzo sisebenzela izinjongo ezimbili:
● Ukuhlanganiswa: Ukunyakaza okuncane kukhuthaza ukukhululwa kwamanzi abhajwe phakathi kukadaka.
● Ukuthutha: Kuqinisekisa ukuthi udaka olujiyile (underflow) luhanjiswa kahle endaweni yokumpompa.
I-Thickener vs. I-Clarifier: Ukuqonda Umehluko
Nakuba ukwakheka komzimba kwama-thickener nama-clarifier kufana, asebenzela izinjongo ezihlukene zokusebenza.
Isici | I-Thickener | I-Clarifier |
Umgomo Oyinhloko | Ukugxilisa. Khulisa kakhulu ubuningi bezinto eziqinile ze-underflow. | Ukucaciswa. Khulisa ubumsulwa boketshezi lwe-overflow. |
Ukulayisha Okuqinile | Phezulu | Phansi |
Ukujula Kombhede | Okujulile (ukuvumela ukucindezelwa) | Okungashoni |
Ukugeleza Okungaphansi | Udaka oluminyene, olufana nokunamathisela | Udaka oluncane, olungaxubene kahle |
Ukusetshenziswa Okujwayelekile | Izinsalela zamaminerali, ukucutshungulwa kwensimbi | Amanzi aphuzekayo, amanzi angcolile alula |
Kungani Izimboni Zisebenzisa IziThickener Zokudilika
Izinzuzo zezomnotho nezemvelo zokujiya okuphumelelayo zinkulu:
● Ukuthola Amanzi Kabusha: Ezimayini, amanzi awumthombo oyigugu. Ama-thickener avumela izimboni ukuthi zibuyisele amanzi acubunguliwe afinyelela ku-80-90% emuva emjikelezweni.
● Izindleko Zokuthutha Eziphansi: Ukususa amanzi kunciphisa kakhulu isisindo kanye nomthamo wemfucuza, kwehlisa izindleko zokumpompa ngamapayipi noma ukuthutha ngamaloli ukuya emadanyini okulahla izinsalela.
● Ukuthobela Imithetho Yezemvelo: Ngokukhiqiza i-underflow ezinzile, ama-thickener asiza ukuvimbela ukuvuza kwamanzi angcolile enqubo emhlabathini nasezimpompontweni ezingaphansi.
Imibuzo Evame Ukubuzwa (FAQ)
Umbuzo: Uyini umehluko phakathi kwe-“underflow” ne-“overflow”?
A: Ku-thickener, i-overflow inguketshezi olucacile phezulu (oluvame ukusetshenziswa kabusha enqubweni). I-underflow ingudaka olujiyile, olunama-solids amaningi phansi (oluvame ukuthunyelwa endaweni yokugcina imfucuza noma ukuhluzwa okwengeziwe).
Q: Kungani amanye ama-thickener esebenzisa amakhemikhali (ama-flocculants)?
A: Ezinye izinhlayiya zinhle kakhulu noma zinezindleko ezingaphezulu ezivimbela ukuhlala ngokwemvelo. Ama-flocculants amakhemikhali e-polymer angezwa ku-feedwell ahlanganisa lezi zinhlayiya ezinhle ndawonye zibe "ama-flocs" amakhulu, okwandisa kakhulu isivinini sazo sokuhlala futhi kuthuthukise ukusebenza kahle kwethangi.
Q: Ukhetha kanjani usayizi ofanele we-thickener?
A: Ubukhulu bunqunywa "ijubane lokuzinza" kwezinhlayiya kanye nesikhathi esidingekayo sokuhlala. Onjiniyela benza "ukuhlolwa kokuzinza" elabhorethri kuslurry ethile ukuze balinganise ukuthi indawo yokuhlangana yehla ngokushesha okungakanani. Indawo yethangi ibalwa ukuze kuqinisekiswe ukuthi izinhlayiya zinesikhathi esanele sokuzinza ngaphambi kokuthi uketshezi lufinyelele emfuleni wokuchichima.
Q: Kwenzekani uma umshini we-rake umisa ukuzungeza?
A: Uma ama-rake ema, izinhlayiya zizoqhubeka nokwakheka futhi zicindezeleke phansi, okungenzeka kudale "ukugcwala ngokweqile kwe-torque." Lokhu kungaholela ekutheni ama-rake abhajwe odakeni. Iningi lama-thickener esimanje anezinhlelo "zokuphakamisa i-rake" ezinyusa izingalo ze-rake ngokuzenzakalelayo uma i-torque iphakeme kakhulu, kuvimbele ukwehluleka komshini.
