Diad gilingan na arina, say panaglinis et onggapo ed pre-cleaner. No onloob lay ilik, ondalan itan ed sayan makina pian naekal iray dutak-ya iparaan iray bengatla pian say arum nin proseso et ondalan ya anggapoy problema.
I. Manunan Gawaen: Pangekal na Magaspang tan Anlemew iran Dutak
Say manunan kimey na pre-cleaner et say panggawa na inmunan, baleg-panlinis ed onsasabin hilaw ya ilik, ya ekalen iray dutak ya angkakabaleg odino anlemew so belat da, ya mainomay ya asikasoen na ontumbok iran kagawaan.
Saray manunan bengatla ya ekalen et kaiba so:
Magaspang iran Dutak:
Angkakabaleg iran bato, laryo, saray bunton na dalin, lubir, plastik a papel, saray piraso na inabel a bag, saray sanga na mais, dayami, saray tipak na kiew
Light Impurities (diad pigaran modelo):
ukis, bukel na dika
Saray Maong ya Impurities (diad pigaran modelo):
Melag iran bato, buer
II. Posisyon ed Flour Mill Process Flow
Say pre-cleaner et kaslakan ya akapuesto ed gapo na seksion na panaglinis, salanti, bilang unonan kagawaan kayari na pangawat na raw grain.
Kaslakan ya Posisyon na Agos na Proseso:
Raw Grain Reception → Pre-Cleaner → Magnetic Separator (optional) → Tempering/Unclean Wheat Silos (Temporary Storage) → Subsequent Cleaning Equipment (Vibrating Separator, Destoner, Scourer, etc.) → Damping & Dilling → Dilling → Dilling →
Say rason no akin ya inyan itan ed sankaunaan et:
Saray malet ya dutak a singa saray angkakabaleg a bato tan metal et makaderal a maong ed saray screen na saray vibrating separator, saray deck na destoners, saray beater elements na scourers, tan direktan mameligro ed kaligenan na saray roller mills no onloob ira ed saray kagawaan ed leksab na ilog.
Saray nababalang ya dutak a singa say twine tan plastic sheeting et mainomay ya manbalot ed saray bearing tan pulley na saray kagawaan ya pangibiahe, ya pansengegan na saray bara tan pakaderal ni ingen na kagawaan.
Say pangekal na dakel a dabok tan anlemew iran dutak et makabawas na dakel a dabok ed saray seksion ed leksab na ilog, ya mamaaligwas ed kaliberliber na operasyon.
III. Prinsipyo na Panagkimey tan Saray Manunan Klase
Saray pre-cleaners et manunan manguusar na prinsipyo na panag-sieving, ya mabetbet ya ikompara ed air aspiration odino magnetic separation pian naekal so dutak.
Walay taloran manunan klase:
1. Vibrating Pre-Cleaner
Say eccentric o vibratory motor so mamapaandar ed tapew na screen pian makagawa na reciprocating odino circular motion. Say materyal et onaabante ya onlukso ed tapew na screen. Say tagey a screen layer (ya walaan na angkakabaleg iran aperture) et walaan na saray magaspang ya dutak, bangta say abeban screen layer (ya walaan na angkakabaleg iran aperture) et walaan na malinis a bukel; saray pinon dutak tan dabok so onlelereg ed screen.
Katangian: Simpli so istruktura, baleg so kapasidad na panagproseso, atagey so inka-epektibo na panag-screen. Saya so kaplesan ya manunan pilien, ya matukoy ed nanduruman gilingan na arina, lalo la ed angkakabaleg tan kalatnaan iran gilingan.
2. Rotary Drum Pre-Cleaner
Walay polygonal odino pabilog ya manpapawil-pawil ya tambol ya walay buer to. Say tambol et matantan ya onliliber. Onloob so materyal ed tambol; legan ya onkukurang, say trigo et onlelereg ed saray abot, bangta saray magaspang ya dutak so ompaway ed sampot na tambol.
Katangian: Mabiskeg so inkagawa to, epektibo ed pangekal na saray magaspang ya dutak, malet so operasyon to. Balet, mas baleg so naala to tan matukoy itan ed saray senaryo ya mankaukolan na atagey ya epektibo ed pangekal na magaspang ya dutak tan baleg ya kapasidad ed panagproseso.
3. Pinitipon ya Pre-Cleaner
Base ed vibrating screen odino drum screen, walay aspiration system to tan magnetic separator. Say aspiration system et mangekal na saray magano ya dutak (dabok, awns, shriveled wheat), tan say magnetic separator et mangekal na magnetic metal contaminants.
Katangian: Nankasakey so pakayari, epektibon panaglinis, medyo melag ya pasen. Matukoy parad modernon gilingan na arina ya walaan na atagey a grado na automation.
IV. Proseso na Pankimey
Diad pangusar na vibrating pre-cleaner bilang alimbawa, say proseso na pantratrabaho et onia:
Infeed: Say raw grain et onloob ed feed inlet na pre-cleaner panamegley na conveying equipment tan parepareho so pangibunog ed tapew na screen.
Pan-screen:
Tagey ya Screen: Saray lukas et angkakabaleg-kaslakan et φ8–12 mm odino rektanggulo iran slot. Saray magaspang a bengatla a singa saray bato, lubir, tan dayami et ag makaloob; onlelereg labat ira ed screen tan ompaway so magaspang ya dutak ya ompaway.
Iskrin ed leksab: Mas melag iray lukas, kaslakan et φ2.5–4.0 mm. Say malinis a trigo et mansiansia ed tapew tan onla ed panlapuan na malinis a ilik. Saray maong a bengatla-dabok, angkekelag a bato, apilat iran bukel-onlelereg tan onlelereg bilang kulang.
Aspiration (no walay kagawaan): Say aspiration system et mangipapaway na saray anlemew ya dutak-awns, shriveled wheat, dabok-legan na panagpakan o panag-screen, tan kolektaen to iratan ed sakey a pasen.
Magnetic Separation (no walay kagawaan): Saray magnet (permanente o electromagnetic) et walad inlet o outlet pian naala tan naekal iray magnetic metal bits.
Ipaway: Linisan iray ulo na ilik ed saray silo parad temporaryon pangisimpenan. Saray magaspang ya dutak, pinon dutak, anlemew ya dutak, tan saray metal ya kontaminado et balang sakey et onla ed sarili dan panagkolektaan.
V. Saray Manunan Teknikal a Parametro tan say Epekto Ra
Say performance na pre-cleaner et direktan mangaapekta ed inkaepektibo tan inkapekder na interon seksion na panaglinis:
Kapasidad na Panproseso: Nepeg ya mipara ed sukat na produksyon na gilingan na arina. Parad 100-ton/day ya gilingan, say kapasidad na pre-cleaner et kaukolan ya 120-150 tons/day (no ikonsidera so peak flow).
Screen Aperture Configuration: Say pampili na kabaleg tan kurti na aperture et importante. No melmelag, nayarin manbara iray screen, tan nayarin agsuston na-screen so pigaran malinis a bukel na saray dutak. No baleg, wala ray magaspang ya dutak ya nayarin ondalan ed saray kagawaan ed leksab na ilog.
Inkaepektibo na Pan-screen: Say proporsyon na saray dutak ya epektibon naekal ed malinis ya bukel. Say epektibon tuloy ya pre-cleaner et nepeg ya mangekal na masulok ya 95% na saray magaspang ya dutak tan baleg a kabiangan na saray anlemew ya dutak.
Naandi so Ilik ed Ipulisay: Say proporsyon na malinis ya ilik ya inlaok ed saray inpaway ya dutak. Saya so manunan pakapatnagan na ekonomya na antis na -mas malinis ya performance. Say atagey ya pakaandi na ilik et mangipapanengneng na pakasasayang na hilaw a materyales tan kaukolan so pananguman ed operasyon.
Self-Cleaning Ability: No kasin saray tapew na screen et mainomay ya nabara tan no kasin wala ray kagawaan ed panaglinis (alimbawa, saray bouncing balls, cleaning brushs) et direktan mangapekta ed inkapekder na tuloytuloy ya operasyon.
VI. Sumaryo
Anggaman medyo simpli so panggawa, say pre-cleaner et walaan na agnasaliwan ya estratehikon posisyon ed sakey a gilingan na arina:
Equipment Protector: Saya so sankaunaan tan sankaimportantian ya proteksion na kagawaan, ya epektibon mangamper ed pakaderal na saray ontumbok ya mabmablin kagawaan (lalo la ed saray roller mill) lapud saray magaspang ya dutak.
Production Continuity Ensurer: Diad pangekal ed saray mainomay ya nasalet ya dutak a singa say twine tan plastic sheeting, naseguro so malet ya operasyon na conveying system tan nabawasan so ag-implanon panaon ya ag-onkikiwas.
Pundasyon parad Inkaepektibo na Proseso: Manggawa na paborabli iran kondisyon na pantratrabaho parad saray kagawaan ed panaglinis, ya mangiter na pankanawnawa ed sikaran makapanpokus ed pangekal na saray dutak ya mipara ed kabaleg na trigo ("same-size impurities"), diad ontan et napaaligwas so inkalapagan ya inkaepektibo na seksion na panaglinis.
Diad piguratibon panangibaga, say pre-cleaner et say "goalkeeper" na gilingan na arina. Diad unaan na interon proseso na produksyon, manguusar itan na mabiskeg tan epektibon paraan pian nasebel iray sankapatnagan tan sankapeligroan ya "managlusob," ya mangiletneg na malet a pundasyon parad maligen tan epektibon operasyon na amin ya ontumbok iran kagawaan ya eksakto.
