I-planifter ingundoqo, intliziyo yecandelo lokusila kwindawo yomgubo yanamhlanje. Ukuba i-roller mill "yingcali yokutyumza," ngoko i-planifter "yinkosi yokwahlula ngokuchanekileyo." Umgangatho wokusetyenziswa kwawo umisela ngokuthe ngqo izinga lokutsalwa komgubo, isivuno, umgangatho wemveliso, kunye nokuzinza kwemveliso yelitye lokusila.
I. Imisebenzi enguNdoqo: Ukuhluzwa nokuHlenga
Umsebenzi ophambili weplanifter kukuhluza ngokuqhubekayo, ngokufanelekileyo, nangokuchanekileyo kwaye uhlele umxube ophuma kwii-roller Mills, oquka amasuntswana obungakanani obahlukeneyo kubandakanya umgubo, ibran, kunye ne-endosperm.
Ukutsalwa komgubo ogqityiweyo:Ukwahlula amasuntswana agqwesileyo adibana nemilinganiselo yomgubo ukusuka kumxube oza kuthunyelwa njengemveliso egqityiweyo ukuya kwinqanaba elilandelayo.
UHlelo lweZitokhwe eziPhakathi:Ukwahlulahlula amasuntswana amakhudlwana angekabi kakuhle ngokwaneleyo ukuya kumabakala ahlukeneyo ngokusekelwe kubukhulu kunye nomgangatho (umz., isiqulatho sebran). La mabanga abandakanya umgubo orhabaxa (i-dunst), i-semolina, i-middlings, kunye ne-bran.
Ukuseka ukuHamba kweNkqubo:Ukuhambisa ngokuchanekileyo isitokhwe ngasinye esihleliweyo kumatshini walo olandelayo omiselweyo kwinkqubo (ezifana neerola ezahlukeneyo okanye izicoci), ngaloo ndlela kwakhiwa uthungelwano lokujikeleza kwayo yonke inkqubo yokusila.
II. Isikhundla kunye nendima kwiPhepha lokuHamba lokuSila umgubo
Iplanifter ayisebenzi yodwa. Idityaniswe nezixhobo zokusila ukwenza iiyunithi "zokusila{1}}zokucoca". Yonke inkqubo yokusila idalwe ngokudibanisa iiyunithi ezininzi ezinjalo kuthotho.
Umjikelo weNkqubo eqhelekileyo:
I-Roller Mill (UkuSila) → I-Plansifter (Ukuhluzwa kunye noHlelo) → iZitokhwe eziHleliweyo → Ngokulandelelanayo ithunyelwe kuMgidi weRola omiselweyo olandelayo okanye uMcoci → uMhlaba osezantsi → Faka iPlansifter elandelayo...
Lo mjikelo uyaphinda, ngokuqhubekayo ukhuhla i-endosperm kwi-bran kwaye uyinciphise ibe ngumgubo.
Uyilo Lwenkqubo:Kwi-100-toni / ngosuku lokusila umgubo, iiplanifters ezininzi ziqhele ukusetyenziswa, nganye inoxanduva lokuhluza imisebenzi ngaphakathi "kweenkqubo" ezahlukeneyo, umzekelo:
Yaphula iSicwangciso seNkqubo:Uphatha izinto ezivela kwi-break rolls. Eyona misebenzi iphambili kukukhupha umthamo omkhulu-womgangatho ophezulu womgubo kunye nebran yokuhlela, i-middlings erhabaxa, kunye ne-middlings ecolekileyo.
INkqubo yokuNciphisa iCwangciso:Uphatha izinto ezivela kwimiqulu yokunciphisa. Umsebenzi wayo kukusila kakuhle kunye nokuhluza amasuntswana e-endosperm asulungekileyo ukuvelisa{1}umgangatho ophezulu, ophantsi{2}}umgubo wothuthu.
Scratch System Plansifter:Ubamba izinto ezivela kwi-scratch rolls. Isebenza ngamasuntswana e-endosperm kunye nezincamatheliso zebran ezincinci zokucoca ngakumbi.
Inkqubo yeTailings Plansifter:Ubamba izinto ezivela kwi-tailings rolls. Iqhuba izitokhwe ezinomxholo ophezulu we-bran, ijolise ukukhupha umgubo obuninzi kangangoko kunokwenzeka ngelixa igcina umgangatho womgubo.
III. Umgaqo wokuSebenza kunye neMiba yoLwakhiwo
Ulwakhiwo olungundoqo:
Ingxowa yeSieve:Izindlu zentsimbi ezide, zahlulwe ngaphakathi zibe ngamacandelo amaninzi azimeleyo okanye "amacandelo."
Izakhelo zeSieve:Amacandelo asebenzayo angundoqo. Isipaki ngasinye sezakhelo sineesefu ezinemilinganiselo eyahlukeneyo (elukwe ngesilika okanye kwinayiloni yenayiloni). Indawo yokuvula umnatha ikholisa ukuba ngcono ukusuka phezulu ukuya ezantsi, okanye iqwalaselwe ngokweemfuno zenkqubo. Izinto eziphathekayo zihamba ngentshukumo ejikelezayo ethe tye ngaphakathi kwezakhelo. Amasuntswana amancinci kunombhobho odlulayo ("i-throughs"), ngelixa amaqhekeza amakhulu ahlala kwindawo yesihluzo ("i-overtails").
Qhuba inkqubo:Ngokuqhelekileyo iqhutywa yinjini ethe nkqo ebekwe phezulu. Ivelisa intshukumo ethe tye, ejikelezayo yenqwelomoya ngokusebenzisa izinto ezichaseneyo. Esi sishukumo sisasaza ngokulinganayo imathiriyeli kumphezulu wesefa, ibangela ukuba ishukume ngaphandle ngokujikelezayo ukuze idibane ngokufanelekileyo nemingxuma.
Inkqubo yokusebenza:
Ukutya:Izinto eziphantsi komhlaba zingena ukusuka phezulu kwiplanifter kwaye zisasazwe kumacandelo ahlukeneyo kunye neendlela ezihamba phambili ezichazwe kwangaphambili.
Ukuhluzwa ngokuqhubekayo:Izinto eziphathekayo, eziqhutywe yi-rotary motion, zidlula ngokulandelelana kwiimigangatho ezahlukahlukeneyo ze-sieve ezinobungakanani obuhlukeneyo be-mesh.
UHlelo kunye nokuQokelelwa:Uluhlu lwe-sieve nganye luhlula izinto eziphathekayo kwizinto ezingaphezulu (zigcinwe) kunye ne- throughs (ezigqithisiweyo). Izinto ezivela kumacandelo ahlukeneyo kunye neendlela zokuhamba ziqokelelwa ngokwahlukileyo ngokusebenzisa iziteshi zangaphakathi.
Ukukhutshwa:Okokugqibela, iivenkile ezininzi ezisezantsi kweplanifter ngaxeshanye zikhupha izitokhwe ezahlukeneyo zomgangatho. Ezi ke ziye zihanjiswe ngokuchanekileyo (kaninzi nge-pneumatically) kwiindawo eziya kuzo.
IV. IiParameters eziphambili zobuGcisa kunye neMpembelelo
Ukusebenza kweplanifter kuyalela ukusebenza kakuhle kwayo yonke inkqubo yokusila:
Indawo yoMphezulu wokuhluzwa:Indawo enkulu yokuhluza ithetha umthamo ophezulu kunye nokuhluzwa okucokisekileyo. Inzuzo engundoqo yeplanifter kukuzuza indawo enkulu yokuhluza ngaphakathi kwendawo encinci yokupakisha ngokupakisha iileya ezininzi. Ilitye lokusila leetoni ezili-100/ngosuku lifuna indawo yokuhluza eyaneleyo elungiselelwe ngokwenkqubo yayo.
Ubumbeko lweSieve:Ukukhethwa kweenkcukacha zesefu (ubalo lwe-mesh, imathiriyeli, ubuninzi be-weave) ngumba ongundoqo woyilo lwenkqubo. Imisela ngokuthe ngqo ukuchaneka kokuhlelwa, umlinganiselo wokuhamba kwezitokhwe ezahlukeneyo, kunye neeparamitha zomgangatho wokugqibela womgubo (njengobungakanani bamasuntswana, umxholo wothuthu).
Ukuhluza ngokuSebenzayo:Ipesenti yomgubo ohlukanayo okhutshwe ngokwenene kwi-stock. Ukusebenza okuphezulu kuqinisekisa "ukutsalwa okuphezulu," ukunciphisa ukuphinda kujikelezwe ngokungeyomfuneko, ukwandisa isivuno somgubo kunye nomthamo, kunye nokunciphisa ukusetyenziswa kwamandla.
IiParameters ezishukumayo:Isantya esijikelezayo kunye ne-eccentricity inquma isantya kunye ne-trajectory yezinto eziphathekayo kwindawo ye-sieve. Ezi zifuna ukuphuculwa okusekwe kwiimpawu zesitokhwe kunye neenkcukacha zesefo.
Ukucocwa kweSieve:Ukuthintela ukumfamekisa (ukuvala), iifreyimu zesefo zihlala zinezixhobo zokucoca (umz., imicu yeseyile, iibhola zerabha) ezitsibela ngaphantsi komnatha ngexesha lokusebenza, zigcina imingxuma icacile.
V. Isishwankathelo: "I-Hub yoKwahlula" yeNkqubo yokuSila
Indima yeplanifter inokuqondwa ngokusebenzisa izifaniso:
Umbindi Wolawulo Lwendlela:Kuthatha "i-traffic" edibeneyo (izinto eziphantsi komhlaba ezivela kwii-roller Mills) kwaye iqondise ngokuchanekileyo isithuthi ngasinye (isuntswana) kwindawo yayo elandelayo echanekileyo ngokusekelwe "kuhlobo kunye nendawo" (ubukhulu kunye nomgangatho).
Umgcini-sango osemgangathweni:Ngohlelo oluchanekileyo, iqinisekisa ukuba kuphela i-endosperm esulungekileyo engena kwinkqubo yokunciphisa, eyenza ukuveliswa komgangatho ophezulu{0} womgubo okhethekileyo. Kwakhona kuthintela ukuphuka kwebran ngokugqithiseleyo ekungcoliseni umgubo, ukuqinisekisa ukucoceka komgubo.
Umqinisekisi weSivuno kunye neNzuzo:Umthamo wokuhluza weplanifter ukholisa ukuba ngumqobo kwimveliso yesingqusho. Ukusebenza kwayo ngokufanelekileyo nozinzo kungundoqo ekufezekiseni isakhono esiyilelweyo somzi-mveliso kunye nesantya sokutsala.
Ngaphandle kweplanifter, ukusebenza kakuhle, ukuchaneka nokuqhubekayo komatshini wokungqusha womgubo bekungenakwenzeka. Ime ngokuzolileyo kwindawo yokusila, iphumeza "imiyalelo yokuhlela" entsonkothileyo kwaye ichaneke ngamawaka emingxuma yangaphakathi yomnatha, emele enye yezona zinto zibalulekileyo kwezobuchwepheshe kuhambo olusuka "ekusila" ukuya "kumgubo ogqityiweyo."
