Monga kasitomala wa Hongyang Feed Machinery, tasonkhanitsa mfundo zofunika kwambiri zogwiritsira ntchito tsiku ndi tsiku komanso kukonza nkhungu ya mphete.
1. Kugwiritsa ntchito ma ring dies atsopano
Diye watsopano wa mphete ayenera kukhala ndi chipolopolo chatsopano cha roller: kugwiritsa ntchito bwino pressure roller ndi chimodzi mwa zinthu zofunika kwambiri zomwe zimakhudza kugwiritsa ntchito diye wa mphete. Pakupanga ndi ntchito yathu kwa nthawi yayitali, tapeza kuti ma ring dies ambiri ali ndi malo ogwirira ntchito osafanana, kutulutsa mabowo ochepa, kuchepa kwa mphamvu zopangira, ndipo ma ring dies atsopano sangathe kupanga zinthu. Zifukwa zambiri ndi chifukwa cha kugwiritsa ntchito kosayenera kwa kukanikiza.
Khalidwe la mphete yatsopano ndilakuti malo ogwirira ntchito ndi athyathyathya, koma kusalala kwa mabowo a maso ndi doko lotsogolera sizikukwaniritsa zofunikira za granulation. Mabowo a maso a mphete yatsopano ali ndi mphamvu yolimba komanso mphamvu yokangana pa chinthucho (makamaka ma ring ring dies ang'onoang'ono), pomwe chipolopolo chakale chimawonongeka kwambiri mbali zonse ziwiri, ndipo chinthucho chimatha kulowa mu groove yochepetsera kupanikizika kuchokera ku zigawo zosweka za chipolopolo cha roller, zomwe zimapangitsa kuti ma bowo a maso asatuluke bwino kapena asatuluke konse kuchokera m'mabowo a maso mbali zonse ziwiri za mphete yatsopano. Chifukwa chake, ndikofunikira kuti mphete yatsopano ikhale ndi chipolopolo chatsopano cha roller kuti mugwiritse ntchito. Onetsetsani kuti ntchito yothandizira imatenga maola opitilira 100, ndikuwonetsetsa kuti malo ogwirira ntchito a mphete yatsopano apanikizika mofanana, ndipo kuti kuphulika kwa mabowo a maso ndi kuchuluka kwa kupukuta zikwaniritse zofunikira. Pokhapokha ndi pomwe ntchito yabwino kwambiri ya mphete ingapezeke. Mfundo yogwiritsira ntchito ma pressure roller a mphete ndi yakuti mphete iliyonse iyenera kukhala ndi ma pressure roller osiyana kumayambiriro kwa kugwiritsa ntchito, ndipo ma roll shells omwewo sangagwiritsidwe ntchito ndi ma ring shells ena motsatizana.
2. Mphete yatsopano yofewa yopera
Bowo la mphete lisanachoke ku fakitale, limakhala litapukutidwa ndi chodulira, koma mulingo wake wochepa sunafike pamlingo wosalala wa pamwamba pa galasi. Kuphatikiza apo, pali zinthu zapadera zomwe zimatsala panthawi yotenthetsera, monga zigawo za oxide. Chifukwa chake, mukamagwiritsa ntchito, dzenje la mphete liyenera kuphwanyidwa ndi mafuta a ufa ndi mchenga wabwino.
Tengani ufa (mpunga wamafuta ndiye wabwino kwambiri) kuti muwonetse chinyezi. Onjezani madzi pafupifupi 4%, kenako onjezerani mafuta okwanira kuti musakanize mofanana. Gwirani zinthuzo mu mpira ndi dzanja, ndipo zimakhala zosavuta kuzimwaza mosavuta (zonyowa pang'ono kuposa zinthu zomwe zimazimitsidwa ndi nthunzi nthawi zonse). Choyamba, tsukani mphete ndi zinthu zosakaniza kwa mphindi zitatu. Ngati porosity yawoneka kuti ili pamwamba pa 98%, mchenga wabwino ukhoza kuwonjezeredwa kuti utsukidwe ndi kupukutidwa. Kuchuluka kwa mchenga wabwino kwambiri komwe kumawonjezeredwa ndi gawo limodzi mwa magawo asanu kapena gawo limodzi mwa magawo anayi a zinthu zamafuta, ndipo kuyenera kuwonjezeredwa nthawi 4-5 kapena kuposerapo. Nthawi iliyonse mchenga wabwino ukawonjezedwa, ndikofunikira kuwona kusintha kwa mphamvu yamagetsi ya host. Mphamvu yamagetsi siyenera kupitirira 70% ya mphamvu yamagetsi yanthawi zonse. Pokhapokha ngati mphamvu yamagetsi yanthawi zonse yakhazikika, mchenga wabwino kwambiri ungawonjezedwe. Yang'anani momwe zinthuzo zimatulutsidwira. Ngati zinthuzo sizili zouma kwambiri ndipo pali utsi, ziyenera kuyambitsidwa ndi kutentha kwakukulu kwa zinthuzo. Lolani zinthuzo zizizire musanatsukidwe. Ngati zinthuzo zauma kwambiri ndipo kugwedezeka kwa makina a pellet kumawonjezeka kwambiri panthawi yotsuka, mafuta ena ayenera kuwonjezeredwa moyenera kuti dzenje la die lisatseke kapena pini yotetezera ya makina a pellet isasweke. Onjezani mchenga wosalala ndikupera kwa mphindi 20-30, kenako gwiritsani ntchito mafuta kutulutsa zinthu zomwe zili ndi mchenga wosalala kuchokera mu dzenje la die, kulola mafuta kudzaza dzenje la die. Onetsetsani kuti liwiro la dzenjelo lili pamwamba pa 98% ndikutsuka makinawo. Chifukwa cha kukula kosavuta kwa mpata pakati pa ma pressure rollers panthawi yotsuka mphete ya die, kuti muwonetsetse kuti kupanga bwino mutatha kuyamba ndi kudyetsa, ndikofunikiranso kuyang'ana ndikusintha mpata pakati pa ma pressure rollers kamodzi.
3. Chithandizo cha mphete yotchinga:
① Dyenje la die limakhala lotsekedwa. Ngati ndi lotseguka lalikulu (D2.5mm kapena kupitirira apo), likhoza kubooledwa ndi chitsulo choboolera kapena kubooledwa ndi chitsulo cha simenti. Dziwani kuti chitsulo choboolera kapena chitsulo chogwiritsidwa ntchito chiyenera kukhala chochepera 0.2mm cha dzenje logwira ntchito;
② Ngati kukula kwa mbole ya mphete yotsekedwa kuli kochepera D2.5mm, zimakhala zovuta kuswa ndi chobowola mfuti kapena msomali wachitsulo, ndipo chobowola kapena msomali wachitsulo watsekedwa mu dzenje la die ndipo sungathe kuchotsedwa: mphete ya mphete ikhoza kuphikidwa mu mafuta, mafuta kapena mafuta a nyama kapena masamba angagwiritsidwe ntchito, ndipo mafuta akhoza kutenthedwa kutentha kwambiri kuti apange carbonization ya chakudya mu dzenje la die, zomwe zimathandiza kutulutsa. Njira yogwiritsira ntchito: Ikani mphete ya mphete mu chidebe chachitsulo, onjezerani mafuta a injini kapena mafuta a nyama ndi masamba, ndipo pamwamba pa mafuta payenera kumiza mphete ya mphete. Chidebe cha mafuta chiyenera kukhala chokwera mamita 0.5 kuposa pamwamba pa mafuta (makamaka ndi chivundikiro) kuti mafuta asasefukire atatenthedwa, zomwe zimayambitsa ngozi. Zonse zikakonzeka, zitenthetseni pa moto wochepa ndikulamulira kutentha kwa maola 6-10 mutawiritsa. Zakudya zamapuloteni ambiri zimatenga maola 8-10;
③ Musatulutse nthawi yomweyo mukatha kuphika, chifukwa kutentha kwa mphete kumakhala kwakukulu panthawiyi, komwe kudzaumitsa ndi kulimbitsa chakudya chomwe chili mu dzenje la mphete, zomwe sizingathandize kutulutsa. Iyenera kuziziritsidwa pamodzi ndi mafuta kwa maola pafupifupi awiri, kenako nkuchotsedwa ndikuyiyika, kenako tinthu tating'onoting'ono tosakaniza ndi mafuta tiyenera kugwiritsidwa ntchito kutsuka mphete ya mphete. Poyamba kutsuka, zinthu zochepa ziyenera kuperekedwa, ndipo momwe makina otulutsira, mphamvu ya makina otulutsira, ndi kugwedezeka kwa makina ziyenera kuwonedwa. Kudyetsa sikuyenera kukhala kofulumira kwambiri kuti mphete ya mphete isasweke chifukwa cha kupanikizika kwambiri kapena pini yotetezera ya makina otulutsira mphete isasweke. Kutsuka mphete ya mphete mpaka porosity ifike pa 98%.
