Kwadalwa ngo 10.26
Ukukhishwa Kwesilo, Ukuphakelwa Kanye Nemishini Yokuhambisa: Ama-auger, Ama-elevator Kanye Nezomoya
Ukukhishwa kwesilo kanye nemishini yokudla kufanele kuhambisane nokuziphatha kokugeleza kwento, hhayi nje amathani, ngoba umgodi wokuphuma ongahambisani kahle uyimbangela evame kakhulu yokwakheka kwebhuloho, imigodi emise okwesitsha kanye nemigqa emile. Ukukhetha kuqala ngokuziphatha kokugeleza okukhulu ngokumelene nokugeleza kwesihluzo, bese kukhetha phakathi kwe-screw, ibhande, i-bucket-elevator, i-chain kanye nokudlulisa komoya, okusekelwa izidlulisimishini ezinyakazayo, izibhamu zomoya, ama-aeration pads noma ukubuyiselwa kwaphansi okunyakazayo. Ukwenza i-interface ibe ngokufanele kuguqula isilo sokugcina esimile sibe ukudla okuthembekile, okulinganiselwe kwephrosesi elingezansi.
Isilo esigcwalayo ngokuhlanzekile kodwa esikhipha ngokungahambi kahle siyawuchitha umgomo wokugcina impahla ngobuningi. Ukuxhumana kokukhipha nokuhambisa—konke kusukela emlonyeni we-hopper kuya ku-conveyor yokuqala—kunquma ukuthi impahla ihamba ngezinga elilawulwayo noma ivale uhlelo. Ukucacisa le mishini ngokususelwa ezintweni zokugeleza kwempahla yikho okuhlukanisa umugqa wokusebenza wokusingatha impahla ngobuningi emthwalweni wokulungisa ongapheli.
Ukuziphatha Kokukhipha Kuqala Ngokukhetha Ukugeleza Kwesisindo Ngokuqhathanisa Nokugeleza Kwe-Funnel
I-geometry ye-hopper inquma ukuthi yonke ibhedi iyanyakaza noma ingxenye emaphakathi kuphela, futhi lokho kukhetha okukodwa kuqhubela phambili yonke idivayisi elandelayo. Ama-silo e-mass-flow anezindonga eziqondile nezingenalutho ukuze zonke izinto zingaphakathi ziqhubekele ngasemgodini wokuphuma, okunikeza ukuziphatha kwe-first-in-first-out, isikhathi sokuhlala esifanayo futhi akukho zindawo ezimile. Ama-silo e-funnel-flow asebenzisa ama-hopper angajulile lapho kuphela umsele omaphakathi ogelezayo, okushiya into engasasebenzi ezindongeni engase ibe neqhubu, ihlukanise noma yonakale.
Into enokugeleza okungekuhle—i-fly ash enamathelayo encane, i-mineral concentrate emanzi, i-biomass enezintambo—idinga i-mass flow ukuze igweme ukubhuloga. Ama-granule agelezayo ngokukhululekile, angonakali angabekezelela i-funnel flow ngezindleko eziphansi. I-engeli yokungqubuzana kodonga kanye ne-engeli esebenzayo yokuphumula kwento, elinganiswa elabhorethri, yizinto zokufaka ezinquma lesi sinqumo.

Ukugeleza kwe-Funnel | Kujulile kancane | Yebo (emaphethelweni) | Kugeleza ngokukhululekile, akonakali |
Izidlulisi ze-Screw, Belt, Bucket Ne-Chain Zihlanganisa Ukuthutha Komshini
Ama-conveyor emishini ahambisa impahla ekhishiwe ngedivayisi echaziwe futhi akhethwa ngebanga, ukuphakama kanye nokuguguleka. Ukuphuma kwesilo ngokuvamile kudla kwelinye lamabhidi amane asebenzayo:
1. Isithuthi se-screw (i-auger): sivala kahle, silinganisa ngokunemba, silungele amabanga amafushane avundlile noma atshekile afinyelela cishe ku-20–30 m; sihlupheka ngokuguga ngezimpushana zamaminerali ezihlambayo.
2. Isithuthi sebhande: umthamo ophezulu emabangeni amade, amandla aphansi ngetoni, sidinga indawo yokuvikela isimo sezulu nothuli; asilungile ukuphakamisa okuvundlile.
3. Isiphakamisi samabhakede: siphakamisa impahla ngokuvundlile siyise ezitezi eziningi noma ekhanda lokuhlunga/lokususa uthuli; sihambisana nomugqa wokugcwalisa i-silo.
4. I-chain conveyor (en-masse): ihambisa izinto ezihlukumezayo noma ezishisayo emseleni ovaliwe ngokonakala okuphansi.
Uhlelo lokondla i-silo luvame ukuhlanganisa lezi: ukubuyisela kwe-live-bottom ku-screw, i-screw ku-bucket elevator, i-elevator iye ku-belt esabalalisa enqubweni.
I-Conveyor | Ukuphakamisa | Ibanga | Ukubekezelela ukuhlikumeza |
I-screw auger | Kuphansi–kuphakathi | Kufushane | Kuphansi–kuphakathi |
Ibhande | Lutho | Kude | Phakathi |
I-elevetha yebhakede | Phezulu (mpoqo) | Kufushane | Phakathi |
Iketango (en-masse) | Phansi | Phakathi | Phezulu |
Ukuhambisa Ngomoya Kuthutha Izinto Ezincane Ezihambayo Ngamapayipi
Ukuhambisa ngomoya kuthutha izimpushana nezinhlamvu ezigelezayo ngaphakathi kwepayipi elivaliwe ngomoya, kuqede ukuchitheka futhi kuvumele ukuhamba ngamakhona ezithiyo zemboni. Kufaneleka kusimende, umlotha wendiza, ufulawa kanye nezinhlayiya zamaminerali lapho ukulawulwa kothuli kubaluleke kakhulu kunomnotho wamandla.
Amasistimu esigaba esincishisiwe ahambisa impahla elengayo emoyeni onesivinini esiphezulu ibanga elide; amasistimu esigaba esiminyene aphusha ama-slug ngesivinini esiphansi, okunciphisa ukuguga nokonakala kwemikhiqizo ehlabayo noma ebuthakathaka. Isistimu yokuhambisa ngomoya exhunywe ku-silo isebenzisa i-valve ejikelezayo noma isihambisi sokuphefumula esijikelezayo endaweni yokuphuma, i-compressor noma i-blower, kanye nesihlungi sokwamukela ku-silo yendawo. Ukushintshana kwamanani yizindleko zamandla eziphezulu kunokuhambisa ngomshini, okubuyiselwa ngumzila ovaliwe, ongadingi ukunakekelwa okuningi.
Izihambisi, Ama-Air Cannons Nezindawo Zokungenisa Umoya Zibuyisela Ukugeleza
Lapho impahla inqaba ukuhamba ngamandla adonsela phansi, ama-activator aguqula umbhede obambekile ube umfudlana olawulwayo. Izinsiza ezivamile zokusiza emloyeni we-silo:
· Isiphakeli esidlikizayo: ithreyi elungisiwe elikala izinto eziyinqwaba ezisakazwayo ziyise ku-conveyor ngezinga elimisiwe; lihambisana ne-variable-frequency drive yokulawula ukugcwala.
· I-air cannon (impulse blaster): ikhipha umfutho womoya ocindezelwe ukuze kuqhekeke ukwakheka kwama-arch ezintweni ezinkulu, ezingaqhubeki njalo.
· Ama-aeration pads / amathayela okwenza uketshezi: angenisa umoya onengcindezi ephansi odongeni lwe-hopper ukuze enze ama-powder amancane (usimende, i-fly ash) abe uketshezi ukuze kube nokugeleza okuzinzile.
· Ukubuyiswa kwephansi elinyakazayo (live-bottom): igridi yamapulangwe ashukunyiswa ngamanzi adonsayo edonsa impahla iphume ku-silo enephansi elisicaba, ibuyise indawo yokugcina engasasebenzi.
Ukukhetha kuncike kubukhulu bezinhlayiyana, umswakama nokuthi impahla iyancipha yini ngaphansi kwe-shear; ukwenza umoya omningi ku-powder encane kudala uthuli nje, kuyilapho ukungasebenzisi kahle ama-activator kushiya amabhuloho.
Izisetshenziswa Zokukhipha Kufanele Zilinganiswe Ngokohlelo, Hhayi Ngesilo
Indawo yokuphuma kanye nekholiweya yokuqala zibeka izinga eliphezulu elithembekile lokudonsa, futhi umugqa wonke ukhawulwa isixhumanisi esibuthakathaka kunazo zonke. Isilo esingu-2,000 t esondla uhlelo lwe-20 t/h sidinga kuphela isikulufu esincane, kodwa isilo esifanayo esondla i-kiln engu-200 t/h sidinga indawo yokubuyisela enomphefumulo kanye nokuthathwa kwamabhande amaningi.
Ukulinganisa kusebenzisa ukucindezeka kwempahla kanye nobukhulu bendawo yokuphuma kusukela ekuhlolweni kokugeleza kwe-Jenike: ububanzi obubalulekile bendawo yokuphuma obuvimbela ukwakheka kwe-arch kungumsebenzi wamandla empahla kanye ne-engeli yengxenye ye-hopper. Hlanganisa lokho ne-feeder elinganiselwe ukudonsa okuphezulu, bese ulinganisa umugqa wokudlulisa ngalokho kuphakama okufanayo kanye nokukhuphuka. Ukucacisa igobolondo lesilo ngaphandle kwalolu chungechunge kushiya umthamo etafuleni.
