Emshinini wokugaywa ufulawa, ukuhlanza kuqala ngesihlanzi-sangaphambili. Lapho nje okusanhlamvu kungena, kungena kulo mshini ukuze kukhishwe ukungcola{2}}kumisa izinto ukuze yonke inqubo isebenze ngaphandle kokuphazamiseka.
I. Umsebenzi Oyinhloko: Ukususa Ukungcola Okumahhadla Nokukhanya
Umsebenzi oyinhloko wokuhlanza-kwangaphambilini ukwenza ukuhlanza kokuqala,{1}}okukhulu{1}}kwesilinganiso sokusanhlamvu okuluhlaza okungenayo, ukususa ukungcola okungaba kukhulu kakhulu ngosayizi noma okuncane kakhulu ngesisindo, okusingathwa kalula ngezinto ezisetshenziswayo ezilandelayo.
Izinto eziyinhloko zokususwa zihlanganisa:
Ukungcola Okumaholo:
Amatshe amakhulu, izitini, amagaqa omhlaba, intambo, amashidi epulasitiki, izingcezu zezikhwama ezilukiweyo, izikhwebu zombila, utshani, amapulangwe
Ukungcola Okukhanyayo (kwamanye amamodeli):
amakhoba, imbewu yokhula
Ukungcola Okuhle (kwamanye amamodeli):
Amatshe amancane, izinhlayiya zesihlabathi
II. Isikhundla Ekugelezeni Kwenqubo Yokugaya Ufulawa
Isihlanzi{0}}sangaphambili sivame ukubekwa ekuqaleni kwesigaba sokuhlanza, okungukuthi, njengesisetshenziswa sokuqala ngemva kokwamukela okusanhlamvu okungaphekiwe.
Isikhundla Esijwayelekile Sokugeleza Kwenqubo:
Ukwamukela Okusanhlamvu Okuluhlaza → Ngaphambi-Okuhlanzekile → Isihlukanisi Sibuthe (kuyakhetheka) → Izisele Zikakolweni Ezishisayo/Ezingcolile (Isitoreji Sesikhashana) → Izisetshenziswa Zokuhlanza Ezilandelayo (Isihlukanisi Esidlidliza, I-Destoner, Scourer, njll.) → I-Damping & Conditioning → Ukugaywa
Isizathu sokuyibeka phambili kakhulu yilesi:
Ukungcola okuqinile njengamatshe amakhulu nezinsimbi kungalimaza kakhulu izikrini zezihlukanisi ezidlikizayo, amadekhi ezinto ezisusa amatshe, izinto ezishayayo zama-scourers, futhi kusongela ngokuqondile ukuphepha kwezigayo uma kungena emishinini engaphansi komfula.
Ukungcola okuguquguqukayo okufana ne-twine ne-plastic sheeting kusonga kalula kumabhere kanye nama-pulleys emishini yokudlulisa, kubangela ukuvinjwa kanye nokulimala kwemishini.
Ukukhipha inani elikhulu lothuli nokungcola okulula kunciphisa kakhulu ukugxilwa kothuli ezingxenyeni ezingezansi, ukuthuthukisa indawo yokusebenza.
III. Isimiso Esisebenzayo Nezinhlobo Eziyinhloko
{0}}Abahlanzi bangaphambili basebenzisa umgomo wokusefa, ovame ukuhlanganiswa ne-air aspiration noma ukuhlukaniswa kazibuthe ukuze bathole ukususwa kokungcola.
Kunezinhlobo ezintathu eziyinhloko:
1. Ukudlidliza-Ngangaphambili
I-eccentric motor noma i-vibratory motor ishayela indawo yesikrini ukuze yenze ukunyakaza okuhambisanayo noma okuyindilinga. Okubalulekile kuya phambili ngokugxuma okungaphezulu kwesikrini. Isendlalelo sesikrini esingaphezulu (enezimbobo ezinkulu) sigcina ukungcola okumaholo, kuyilapho isendlalelo sesikrini esiphansi (enezimbobo ezincane) sigcina okusanhlamvu okuhlanzekile; ukungcola okuhle nothuli kuwela esikrinini.
Izici: Isakhiwo esilula, umthamo omkhulu wokucubungula, ukusebenza kahle kokuhlola okuphezulu. Lena inketho yamanje evamile, efanele izigayo zikafulawa ezihlukahlukene, ikakhulukazi ezinkulu nezimaphakathi-ezinosayizi.
2. I-Rotary Drum Pre{1}}I-Cleaner
Ifaka isigubhu esizungezayo esiyi-polygonal noma esiyindilinga esinezimbobo. Isigubhu sizungeza kancane. Izinto zingena esigubhu; njengoba ujikeleza, ukolweni uwela ezimbotsheni, kuyilapho ukungcola okumahhadla kukhishwa ekupheleni kwesigubhu.
Izici: Ukwakhiwa okuqinile, okuphumelelayo ekususeni ukungcola okuqinile, ukusebenza okuzinzile. Nokho, inonyawo olukhudlwana futhi ifanele izimo ezidinga ukusebenza kahle kokususa ukungcola okumahhadla kanye namandla amakhulu okucubungula.
3. Isihlanzi Esihlanganisiwe Sangaphambili-
Ngokusekelwe kusikrini esidlidlizayo noma isikrini sesigubhu, sihlanganisa isistimu yokulangazelela kanye nesihlukanisi kazibuthe. Isistimu yokulangazelela isusa ukungcola okulula (uthuli, izinsika, ukolweni oshwabene), futhi isihlukanisi sikazibuthe sisusa ukungcola kwensimbi kazibuthe.
Izici: Ukusebenza okudidiyelwe, ukuhlanzwa okusebenzayo, umkhondo wezinyawo ohlangene. Ifanele izigayo zikafulawa zesimanje ezinezinga eliphezulu lokuzenzakalela.
IV. Inqubo Yokusebenza
Ukusebenzisa okokuhlanza ngaphambili{0}}okudlidlizayo njengesibonelo, inqubo yokusebenza imi kanje:
Okuphakelayo: Okusanhlamvu okuluhlaza kungena endaweni yokuphakelayo-yokuhlanza kwangaphambili ngokuthutha okokusebenza futhi kusatshalaliswe ngokulinganayo endaweni yesikrini.
Ukuhlola:
Isikrini Esiphezulu: Ukuvuleka kukhulu-ngokujwayelekile φ8–12 mm noma izikhala eziwunxande. Izinto ezimahhadlahhadla njengamatshe, intambo, notshani azikwazi ukudlula; bavele bashibilike esikrinini baphume ukungcola okumaholoholo.
Isikrini Esingezansi: Ukuvuleka kuncane, ngokuvamile ngu-φ2.5–4.0 mm. Ukolweni ohlanzekile uhlala phezulu futhi uhamba uya endaweni ehlanzekile yokusanhlamvu. Izinto ezinhle{4}}uthuli, amatshe amancane, izikhwebu eziphukile{5}}ziyawa futhi ziyalahlwa njengosayizi ongaphansi.
I-Aspiration (uma ihlomile): Isistimu ye-aspiration ikhipha ukungcola okuncane-izinsika, ukolweni oshwabene, uthuli{1}}ngesikhathi sokuphakelwa noma ukuhlolwa, futhi ikuqoqe endaweni eyodwa.
Ukuhlukaniswa kukaMazibuthe (uma kuhlomile): Izibuthe (ingunaphakade noma i-electromagnetic) zihlala endaweni yokungena noma ephumayo ukuze zibambe futhi zikhiphe izingcezu zensimbi kazibuthe.
Ukukhipha: Hlanza izinhloko zokusanhlamvu ezinqolobaneni ukuze ugcinwe okwesikhashana. Ukungcola okumaholo, ukungcola okuhle, ukungcola okuncane, nokungcola kwensimbi ngayinye iya ezindaweni zayo zokuqoqa.
V. Amapharamitha Abalulekile Wezobuchwepheshe kanye Nomthelela Wawo
Ukusebenza{0}}kokuhlanza ngaphambilini kuthinta ngqo ukusebenza kahle nokuzinza kwaso sonke isigaba sokuhlanza:
Amandla Okucubungula: Kufanele afane nesikalo sokukhiqiza somshini wokugaya ufulawa. Ngomshini wokugaya ongu-100-wamathani/ngosuku, umthamo wokuhlanza ngaphambilini ngokuvamile udinga ukuba amathani angu-120-150/ngosuku (kucatshangelwa ukugeleza okuphezulu).
Ukucushwa Kwembobo Yesikrini: Ukukhetha usayizi wokuvula nokuma kubalulekile. Uma zizincane kakhulu, izikrini zingase zivaleke, futhi okunye okuhlanzekile kungase kuhlolwe ngokungalungile nokungcola. Uma kukhulu kakhulu, okunye ukungcola okungamahhadla kungase kudlulele emishinini esezansi nomfula.
I-Screening Efficiency: Ingxenye yokungcola isuswe ngempumelelo ohlamvu oluhlanzekile. Isicoci sangaphambi kwesikhathi{1}}esisebenza kahle kakhulu kufanele sisuse ngaphezu kuka-95% wokungcola okumaholo kanye nengxenye ebalulekile yokungcola okuncane.
Ukulahlekelwa Okusanhlamvu Ekunqatshweni: Ingxenye yokusanhlamvu okuhlanzekile okuxutshwe nokungcola okukhishiwe. Lesi inkomba yezomnotho eyinhloko{1}}yokusebenza okuhlanzekile kwangaphambili. Ukulahlekelwa okusanhlamvu okuphezulu kubonisa ukumoshakala kwempahla futhi kudinga ukulungiswa kokusebenza.
-Ikhono Lokuzihlanza: Ukuthi indawo yesikrini ijwayele ukuvaleka nokuthi ingabe izinto zokuhlanza (isb., amabhola abhampayo, amabhulashi okuhlanza) zihlonyiselwe ngokuqondile kuthinta ukuzinza komsebenzi oqhubekayo.
VI. Isifinyezo
Nakuba kulula ekwakhiweni,{0}}isicoci sangaphambili sibambe indawo yesu engenakushintshwa endaweni yokugaya ufulawa:
Isivikeli Sezisetshenziswa: Sisebenza njengesithiyo sokuqala nesibaluleke kakhulu sokuvikela okokusebenza, sinqanda ngempumelelo umonakalo emishinini ebizayo elandelayo (ikakhulukazi izigayo zamarola) okubangelwa ukungcola okumaholo.
Isiqinisekisi Sokuqhubeka Kokukhiqiza: Ngokususa ukungcola okuthandelana kalula njenge-twine ne-plastic sheeting, kuqinisekisa ukusebenza okuzinzile kwesistimu yokudlulisa futhi kunciphisa isikhathi sokuphumula esingahlelelwe.
Isisekelo Sokusebenza Kahle Kwenqubo: Sakha izimo zokusebenza ezivumayo zempahla yokuhlanza ecolekileyo ephansi komfula, ebavumela ukuba bagxile ekukhipheni ukungcola okufana nosayizi nokolweni ("{0}}ukungcola okunosayizi ofanayo"), ngaleyo ndlela kuthuthukise ukusebenza kahle okuphelele kwesigaba sokuhlanza.
Ngomqondo ongokomfanekiso, -ohlanzayo "unguzinti" wokugaya ufulawa. Imi phambili kuyo yonke inqubo yokukhiqiza, isebenzisa indlela eqinile nephumelelayo ukuvimba "abahlaseli" abasobala kakhulu futhi abayingozi, ibeka isisekelo esiqinile sokusebenza okuphephile nokusebenza kahle kwayo yonke imishini yokunemba elandelayo.
