Yimiphi imingcele yenqubo yesikrini esidlidlizayo? Ungabala kanjani?

/in /by

Isikrini esidlidlizayo ngokuvamile sinendawo yokusebenza enokhahlo, njengokushisa okuphezulu nothuli oluphakeme. Ukuze kugcinwe ukusebenza okujwayelekile kwesikrini esidlidlizayo ngaphansi kwalesi simo, kubeka phambili izidingo eziphakeme kunqubo yenqubo yesikrini esidlidlizayo. Amapharamitha wenqubo yesikrini esidlidlizelayo ayini? Ungayikhetha kanjani futhi uyibale le mingcele? Konke okudingeka sikuqonde. Amapharamitha wenqubo enengqondo angaphinde aqinisekise ukusebenza okujwayelekile kwesikrini esidlidlizayo, futhi kwezinye izindlela futhi kunweba impilo yesevisi yesikrini.

Inqubo nemingcele kwesikrini isixwayisi

1. I-angle yokuthambekela kwesikrini esidlidlizayo

I-engeli yokuthambekela kobuso besikrini isho i-engeli ephakathi kobuso besikrini sesikrini esidlidlizayo nolayini ovundlile. Usayizi we-angle yokuthambekela uzothinta ijubane elihambayo lezinto ezomisiwe. Lapho i-angle yokuthambekela kwendawo yesikrini inkulu kakhulu, isivinini sokuhamba sento naso sizokwenyuka. Yize ingakhuphula ivolumu yokukhiqiza, izokwehlisa ukusebenza kahle kokuhlolwa. Ngokuphambene nalokho, uma i-angle yokuthambekela incane kakhulu, ukusebenza kahle kokuhlola kuzokwandiswa, kepha amandla okukhiqiza azoncishiswa. Izikrini zomugqa ngokuvamile zifakwa ngokuvundlile nge-engela yokuthambekela okungu-zero. Izikrini eziqondile ezivundlile ngokuvamile zikulungele kuphela ukuhlolwa kwezinto ezinosayizi wezinhlayiyana ezingama-40mm noma ngaphansi, noma zokwehla kwamanzi emzimbeni, ukomisa nokususa amalahle. Uma isetshenziselwa ukuhlola izinto ngosayizi wezinhlayiyana ezingama-50mm noma ngaphezulu, isikrini esiqondile kufanele sibe ne-engeli, futhi i-angle yokuthambekela icishe ibe ngu-5º ~ 10º.

2. Isixwa amplitude yesikrini nobuningi

Ukudlidliza i-amplitude yesikrini kubhekisa ebangeni nasekuqineni kokudlidliza kwebhokisi, futhi imvamisa ibhekisa kwinani lokudlidliza ngeminithi yebhokisi lesikrini. Lapho ubukhulu bukhulu, imvamisa yokuhlola iphakeme, futhi ijubane lokuhamba nokusheshisa kwebhokisi lesikrini nakho kukhulu. Lapho kusikwa izinhlayiya ezigqwabayo, kunconywa ukwamukela ukuphakama okukhulu kanye nobuningi obuphansi; ngakolunye uhlangothi, lapho kusikwa izinhlayiya ezinhle, i-amplitude encane kanye nemvamisa ephezulu kufanele igcinwe.

3. Ubude nobubanzi besikrini esidlidlizayo

Lapho ezinye izimo zokuhlola zifana, umkhiqizo ikakhulukazi uncike kububanzi bendawo yesikrini, futhi ukusebenza kahle kokuhlola kunqunywa ikakhulukazi ubude besikrini. Kepha akusho ukuthi ububanzi bendawo yesikrini bukhulu ngangokunokwenzeka, ngoba lapho ubuso besikrini bukhulu kakhulu, ukuphakelwa kuzobe kungalingani futhi ukuqina kuzoba kubi. Ubuso besikrini bude kakhulu futhi abungeke bukhuphule ukusebenza kokuhlolwa, ngakho-ke kufanele kukhethwe indawo yesikrini yobude nobubanzi obufanele. Ngakho-ke, isilinganiso sesici ngokuvamile siyi-2: 3. Okokuhlolisiswa kwezinto ezimahhadlahhadla, ubude bendawo yesikrini bungu-3.5 ~ 4m. Okokuhlolwa kwezinto ezisemkhatsini nezinemibala emihle, ubude bendawo yesikrini bungu-5 ~ 6m; ubuso besikrini obuhlolwe ngaphambilini bungaba bufushane kunobuso bokugcina besikrini Kufanele bube bude.

4. Ukuphonsa i-angle yesikrini esidlidlizayo

I-engeli yokuphonsa yesikrini esidlidlizelayo isho i-engeli eyakhiwe phakathi kokuqondiswa komzimba webhokisi nendawo yesikrini lapho ibhokisi lihamba, okungukuthi, i-engeli yokuqondisa leyo nto ebusweni besikrini iphonswa ngamandla. Uma inkulu i-engeli yokujikijela, isivinini sokuhamba kokuhamba kancane kwezinto, esizoboniswa ngokwanele, esifanele izinto zokwakha okunzima ukuskena. Okuncane kwe-engeli yokuqagela, ijubane lokunyakaza kwezinto, liyashesha, elilungele izinto ezilula ukuskena.

Ukukhethwa nokubalwa kwamapharamitha wesikrini esidlidlizayo

1. Inkomba yokuphonsa

Ngokwesipiliyoni, kuya ngohlobo lwezinto ezizocutshungulwa, inkolelo-mbono kanye nomkhuba wokukhiqizwa kwe-sieving kufakazele ukuthi usayizi wezinhlayiyana ungaphansi kuka-3/4 wosayizi wemesh, obizwa nge- “sieve elula”; usayizi wezinhlayiyana mkhulu kunosayizi wemesh 3/4, obizwa ngokuthi “kunzima ukusika ama-granules”; ukusondela kobubanzi be-granules kusayizi we-sieve, kulukhuni kakhulu ukungena kusihlungo. Iningi lisebenzisa inkomba yokujikijela ngejubane eliphakathi 1.75-3.3.

2. Ukuthambekela kokufaka

I-angle yokuthambekela kokufaka ihlobene namandla wokucubungula nokusebenza kahle kokuhlola kwesikrini esidlidlizayo.

(1) Ukuhlukaniswa kwezinto nokuhlukaniswa, njll.: Ukufaka i-engeli = 0 °;

(2) Isikrini sokudlikiza komugqa: ukuchelela: ukufakwa kwe-engeli = 0 °, kubi uma kunesidingo; lapho okokusebenza kungaphezu kwama-50 mm, i-angle yokufaka = 5 ~ 10 °; lapho okokusebenza kungaphansi kwama-40 mm: i-angle yokufaka = 0 °; Okodaka, ukususwa kwangaphakathi, nokoma emzimbeni: I-angle yokufaka = -5 ° ~ 0 °.

3. Ukufakwa kwe-angle direction angle

Inani lesikrini sokudlidliza komugqa liyi-30 ~ 60 °, yesikrini sokudlidliza komugqa, ngokuvamile β = 45 °. Isizathu ukuthi sinokuguquguquka okuhle, isivinini sokuhamba okuphezulu nokukhiqiza okuphezulu.

4. Ubude nobubanzi bendawo yesikrini

Bala indawo edingekayo ngokusho kokukhiqizwa kwangempela kwesisefo, umkhiqizo, nosayizi wezinhlayiyana zento ezohlolwa. Uma kuyisikrini esinezendlalelo eziningi, kufanele kubalwe ungqimba ngongqimba, futhi inani eliphakeme elibaliwe kufanele lithathwe, futhi kufanele lihanjiswe ngokuya ngezinga.

(1) Ubude bendawo yesikrini: ngaphansi kuka-3.6mm, isikhawu sesigaba ngasinye singu-0.6m; ngenhla kuka-3.6mm, isikhawu sesigaba ngasinye singu-0.9m;

(2) Ububanzi besikrini: ngaphansi kuka-3.0mm, isikhawu sesinyathelo ngasinye singu-0.3m; ngenhla kuka-3.0mm, isikhawu sesinyathelo ngasinye singu-0.6m.

5. Vibration sitsheke engela

I-engeli yokuthambekela kokudlidliza imvamisa ingu-45 °, kanti i-engeli enyakazayo ingafinyelela kuma-60 ° kwezinye izinto ezilukhuni ezifana namatshe agayiwe, i-coke, ne-sinter.

6. Ijubane elihambayo lobuso besikrini nobukhulu besendlalelo sezinto

Ijubane elihambayo lezinto eduze kwesikrini imvamisa liyi-0.12 ~ 0.4m / s, hhayi ngaphezulu kwe-1.2m / s. Okwesikrini esiyindilinga esiyindilinga, ijubane elihambayo lezinto eduze kwesikrini lihlobene ne-angle yokuthambekela kobuso besikrini. Ubudlelwano phakathi kobukhulu δ besendlalelo sezinto nosayizi wesihlungo u-a siboniswa ngakwesokudla: δ≤ (3 ~ 4) a; ubudlelwane obuphakathi kobukhulu nobukhulu bezinhlayiyana d0 zento esesikrinini buyakhonjiswa ngakwesokudla: δ≈ (2 ~ 2.5) d0.

7. Isixwa amplitude yesikrini nejubane lokuphotha

Ukuphakama ngokuvamile kuphakathi kuka-2 ~ 8mm. Lapho isihlungo sincane noma sisetshenziselwa ukoma, thatha inani elincane. Lapho imbobo yesisefo inkulu, khetha inani elikhudlwana. Ngejubane lokuphotha, kungabalwa ngokulandelayo:

Vibrating screen amplitude and spindle speed

A yi-amplitude (mm); n isivinini sokuphotha (n / min)

Okuqukethwe okungenhla kufingqa ukuthi yiziphi izinqubo zenqubo yesikrini esidlidlizelayo, njengokuthambekela kobuso besikrini, ukuphakama nobuningi, ubude nobubanzi bendawo yesikrini, njll. Isikrini esidlidlizayo sithola umphumela omuhle wokusebenzisa.
