Sisebenza kanjani isikrini sokudlidliza?

Izikrini zokudlidliza zisetshenziswe kabanzi kwezimayini, insimbi, amalahle, ukongiwa kwamanzi, ezokuthutha kanye nezimboni zamakhemikhali ukuqedela izinqubo ezahlukahlukene, njengokuhlola, ukugreda, ukuwasha, ukukhipha amandla nokuphelelwa amandla kwempahla. Njengesixhumanisi esiphakathi phakathi kwezimayini nokuncibilikisa, ukusebenza kahle kokumbiwa phansi akuthinti ngqo ukukhiqizwa kokusebenza kwezimbiwa kuphela, kodwa futhi kunomthelela omkhulu ekusetshenzisweni okunengqondo kwezinsizakusebenza zikazwelonke.

Isikrini esidlidlizayo sisebenza ngokusebenzisa ukudlidliza okuzungezisa kabili okwenziwe isidlidlizi. Isisindo esingaphezulu esijikelezayo sesidlidlizi senza ukudlidlizela kwesikrini endizeni, kanti isisindo esiphansi esijikelezayo senza indawo yesikrini idlidlize ingaphezulu lesigaxa. Umphumela wawo ohlanganisiwe Umphumela ukuthi indawo yesikrini ikhiqiza ukudlidliza okuzungezisa kabili. Umzila wayo wokudlidliza uyindawo yendawo eyinkimbinkimbi. Ijika likhonjiswa njengesiyingi endizeni evundlile, futhi likhonjiswe njengesiyingi endizeni ebheke phezulu. I-amplitude ingaguqulwa ngokulungisa amandla entshisekelo wezisindo eziphezulu nezansi ezijikelezayo. Ukulungisa i-engeli yesigaba sendawo yezisindo ezingenhla nezingezansi kungashintsha ukwakheka kwejika lendlela yokuhamba kwesikrini futhi kuguqule umzila wokuhamba wento ebusweni besikrini.

Imishini yesikrini esidlidlizayo ingahlukaniswa: isikrini sokudlidliza kwezimayini, isikrini esikhanyayo esihle sokudlikiza, nesikrini sokudlikiza sokuhlola ngokusho kwesisindo saso.

Izikrini zokudlidliza ezimayini zingahlukaniswa zibe: izikrini ezisindayo, izikrini zokudlidlizisela wena uqobo, izikrini zokudlidliza, izikrini zokunisela, izikrini eziyindilinga zokudlidliza, izikrini zebhanana, izikrini eziqondile zokudlidliza, njll .;

Isikrini sokukhanya sokudlikiza esihle singahlukaniswa sibe: isikrini sokudlidliza esijikelezayo, isikrini esilinganayo, isikrini somugqa oqondile, isikrini sokudlikiza se-ultrasonic, isikrini sokuhlunga, njll.

Isikrini sokudlidliza esivivinyayo: isikrini esibonisa phezulu, isikrini sokudlikiza sesiteleka esiphezulu, isikrini sokuhlola esijwayelekile, isikrini sokudlidliza kagesi, njll.

Ngokuya ngethrekhi egijima yesikrini esidlidlizayo, ingahlukaniswa nge:

Ngokwe-trajectory yokuhamba okuhamba phambili: isikrini sokudlidliza komugqa (okokusebenza kuqhubekela phambili ebusweni besikrini kulayini oqondile);

Ngokwe-trajectory yokunyakaza eyindilinga: isikrini esiyindilinga esiyindilinga (izinto zihamba ziyisiyingi ebusweni besikrini);

Ngokwe-trajectory yokunyakaza ephindayo: umshini omuhle wokuhlola (izinto zibuyisela phambili ebusweni bokomisa).

Eminyakeni yamuva nje, yize imishini yokuhlola isixwayisi izuze intuthuko engakaze ibonwe, uhlaka lwethiyori lwezikrini zokudlidliza luzinzile futhi lwavuthwa. Izinhlobo ezahlukahlukene zesikrini esidlidlizayo sethulwe ngokulandelana, kepha izikrini zokudlidliza ezinokusebenza okuphezulu kokuhlola kanye nokukhipha okukhulu bekuhlala kudlidliza. Inkomba entsha yocwaningo ngesihlungo nentuthuko.

Amalahle noma i-ore emayini ensimini yezimayini, noma into echotshoziwe, ngaphambi kokuthi kusetshenziswe noma kuqhutshekwe nakho, kufanele ihlukaniswe ngamabanga amaningana osayizi wezinhlayiyana ezifanayo noma yokwehliswa, isuswe phakathi, isuswe, futhi kwesinye isikhathi inhlanganisela yezinto eziningana. Yebo. Lapho kwenziwa lo msebenzi ongenhla, kuhlale kunenkinga yokufaka izinto ngokusebenzisa izimbobo zobuso besikrini, nokufakwa kwezinto ezintweni ezimbotsheni zobuso besikrini kubizwa ngokuthi yi-sieving. Ngocwaningo ngenqubo yokuhlola izinto zokwakha, kutholakala ukuthi ukuhlolwa kwezinto zingahlukaniswa ngezigaba ezimbili:

1. Izinto ezicijile ezinhle ezingaphansi kosayizi we-mesh zifinyelela ebusweni besikrini ngongqimba wezinto ezibonakalayo owenziwe ngezinto ezi-coarse-grained;

2. Into enhle yezinhlayiya idlula emigodini yesisefo ebusweni besihlungo ukuqedela isihlungo.

Lapho isikrini esidlidlizelayo sisebenza, ama-motors amabili ngokushintshana nangokushintshana azungeze ukwenza i-exciter ikhiqize amandla e-reverse excitation, ephoqa umzimba wesikrini ukuthi ushayele isikrini ukuze sihambe isikhathi eside, ukuze lokho okukuso kuphonswe phambili ngezikhathi ezithile kububanzi obufanele embuthweni wokuzijabulisa. Ukuze uqedele umsebenzi wokuhlola impahla. Ifanele ukuhlola isihlabathi nezinto zokwakhiwa kukamatye, futhi ingasetshenziselwa ukuhlukaniswa komkhiqizo ekulungiseleleni amalahle, ukucubungula amaminerali, izinto zokwakha, amandla kagesi nezimboni zamakhemikhali.

Ingxenye yokusebenza kwesikrini esidlidlizelayo ihleliwe, futhi okokusebenza kuhlolwe ngokuslayida eduze kwendawo yokusebenza. Fixed grid ngesihlungo ingenye esetshenziswa kakhulu concentrators, ngokuvamile esetshenziselwa pre-screening ngaphambi wayichoboza indawo noma wayichoboza naphakathi. Inesakhiwo esilula futhi esivumelana nokukhiqizwa. Ayisebenzisi amandla futhi ingakhipha ngqo i-ore ebusweni besikrini. Okubi okuyinhloko ukukhiqiza okuphansi nokusebenza kahle kokuhlola okuphansi, imvamisa kungama-50-60% kuphela. Ubuso obusebenzayo besikrini esidlidlizelayo sakhiwa yimiphini yokugingqa ehlelwe nendawo. Kukhona amapuleti emigodini, futhi izinto ezinamatshe amnandi zidlula ezikhaleni eziphakathi kwama-roller noma amapuleti.

Ukuze uqedele kahle inqubo yokuhlola okokusebenza, isimo sokuhamba okuhlobene phakathi kwento nendawo yesikrini kufanele seneliswe. Ngakho-ke, ibhokisi lesikrini lesikrini esidlidlizayo kufanele libe nezici ezifanele zokuhamba, ngakolunye uhlangothi, lingenza okubonakalayo esikrinini kukhululeke.

Ngakolunye uhlangothi, kungenza izinhlayiya eziminyene zivinjwe emigodini yesisefo ukubaleka, futhi igcine izinto ezinamatshe amnandi ngokushelela ngesihlungo. Enqubeni yokukhiqiza yangempela, inqubo yangempela yokuhlola ithi: “Ngemuva kwenani elikhulu lezinto eziphukile ezinosayizi wezinhlayiyana ezihlukile nezinhlayiya ezixubile nezinhle zingena ebusweni besikrini, kuphela ingxenye yezinto ezithinta indawo yesikrini. Kule ngxenye okokusebenza okuxhumana nobuso besikrini, Akuyona ngokuphelele into enhle yezinhlayiya encane kunosayizi we-mesh,
Iningi lezinhlayiya ezisele ezincane ezincane kunosayizi wemeshini zisatshalaliswa kulo lonke ungqimba lwezinto ezibonakalayo.

Ngokuhamba kwebhokisi lesikrini, ungqimba lwezinto ezibonakalayo esikrinini luyakhululwa, ukuze igebe elikhona phakathi kwezinhlayiya ezinkulu likhuliswe ngokwengeziwe, futhi izinhlayiya ezincane zithathe ithuba lokudlula esikhaleni bese zidlulisela kusendlalelo esiphansi ; ngasikhathi sinye, ngenxa yezinhlayiya ezincane eziphakathi kwezinto Igebe lincane, futhi izinhlayiya ezinkulu azikwazi ukudlula. Ngakho-ke, isikhundla sezinhlayiya ezinkulu sanda ngokuqhubekayo ngesikhathi sokuhamba. Ngenxa yalokhu, iqembu eliyizinhlayiyana eliyindidane elihlukanisayo, okungukuthi, ligqinsiwe ngosayizi wezinhlayiyana, lenza umthetho wokuhlelwa ngezinhlayiya ezincane ezansi nezinhlayiya ezigqamile ngaphezulu.

Into enhle yezinhlayiyana efinyelela esikrinini, ngoba usayizi wayo mncane kunosayizi wembobo yesisefo, ungangena kahle esikrinini, futhi ekugcineni uqaphele ukwehlukaniswa kwezinhlayiya ezilukhuni nezinhle futhi uqedele inqubo yokuhlola. “Kodwa, ukwahlukana okwanele ngokwabelana nesikhathi, ngokuvamile kunengxenye yezinhlayiya ezinhle ezisele ezinhlayiyeni ezigqwabile esisefweni futhi azikwazi ukungena ngesihlungo. Ucwaningo lukhombisa ukuthi yize ubukhulu bezinhlayiya ezinhle buncane kunomgodi wesisefo, ubunzima be Ukungena kwabo akufani.Ukuqhathaniswa nezimbobo ze-sieve, kuncane usayizi wezinhlayiyana, kuba lula ukungena ngesihlungo, futhi okuphambene nalokho, kuba nzima kakhulu.
