Chida chopangira mphete ndicho mtima wa mzere uliwonse wopanga mapellet. Maonekedwe ake, zitsulo, ndi mbiri yake ya kutentha zimatsimikiza mwachindunji kuchuluka kwa ntchito, kulimba kwa mapellet, kugwiritsa ntchito mphamvu, ndi nthawi yogwira ntchito. Komabe kusankha mapellet nthawi zambiri kumachepetsedwa kukhala nambala yofanana ndi kabukhu—njira yomwe imasiya phindu lalikulu patebulo. Nkhaniyi imapereka chitsogozo chokhazikika, choyendetsedwa ndiukadaulo cha magawo ofunikira omwe amalamulira magwiridwe antchito a mphete. Imagwiritsa ntchito mabuku ofalitsidwa opanga makina, miyezo ya sayansi ya zinthu, ndi zambiri zamunda kuchokera ku chakudya chambiri ndi ntchito za biomass kuti ipatse mainjiniya, oyang'anira kupanga, ndi akatswiri ogula zinthu njira yosankhira mwadongosolo. Mkati mwake, ikuwonetsa momwe kupanga molondola—komwe kwawonetsedwa ndi akatswiri odzipereka monga Hongyang Feed Machinery—kumasinthira kufotokozera kwa zinthu kukhala zotsatira zoyezeka zopangira. 1. Chifukwa Chake Ring Die Iyenera Kuyang'aniridwa ndi Uinjiniya Mu mzere wamakono wa chakudya kapena biomass pelleting, mphete ya mphete imadya pafupifupi 60-70% ya mphamvu yonse yamakina ya mphete ya pellet. Ndi gawo limodzi lomwe limasintha mash okonzedwa kukhala pellet yogulitsidwa, yonyamulika. Kusintha kwa 10% pa kapangidwe ka die—komwe kumachitika kudzera mu mawonekedwe abwino a dzenje, kutsirizika kwa pamwamba kolimba, kapena chiŵerengero chokwezeka cha kupsinjika—kungapereke mphamvu yochulukirapo ya 8-15% komanso kuchepetsa kwa ma kilowatt-hours pa tani (kWh/t). Mosiyana ndi zimenezi, die yosafotokozedwa bwino kapena yopangidwa molakwika imawonekera ngati kutulutsa kochepa, ndalama zambiri, kutsetsereka kwa roller, kusweka kwa die, ndi nthawi yopuma yosakonzedwa kawirikawiri. Nkhani yachuma ndi yowongoka: die ikuyimira gawo laling'ono la ndalama zonse za mzere, koma kufotokozera kwake kumatsimikizira kupanga bwino kwa dongosolo lonse la pansi. 2. Ma Parameter Asanu Ofunikira 2.1 Chiŵerengero cha Kupsinjika (CR) Chiŵerengero cha kupsinjika ndiye gawo limodzi lofunika kwambiri pa kufotokozera kwa die. Chimawerengedwa motere: CR = Kukhuthala kwa Die Kogwira Mtima (L) / M'mimba mwa Hole (D) Kukhuthala kogwira mtima ndi makulidwe onse a die kupatula kuya kwa cholowera chamfer (cholowera chozungulira kapena chopindika). Chimayimira kutalika kwenikweni komwe zinthuzo zimakumana nako kupsinjika musanatuluke mu die. Malangizo a mafakitale (CPM, 2022; Muyang Technical Handbook, 2023) amaika mitundu ya CR motere: Mtundu wa Chakudya, Mtundu Woyenera wa CR —, — Chakudya cha nkhuku/aqua chokhala ndi starch yambiri (chimanga-soya), 1:8 – 1:10 Chakudya cha ng'ombe/zoweta zokhala ndi ulusi wambiri, 1:10 – 1:15 Ma pellets a utuchi / biomass a nkhuni, 1:6 – 1:12 (matabwa ofewa kupita kumapeto apamwamba) Manyowa achilengedwe, 1:4 – 1:8 Chidziwitso chogwira ntchito: Zomera zambiri zimalephera kufika kumapeto kwapamwamba kwa mtundu wa CR, zikukhulupirira kuti kupsinjika kwakukulu kumatsimikizira kulimba bwino. Mwachizolowezi, izi nthawi zambiri zimawonjezera mphamvu yokoka popanda kusintha kwa PDI (Pellet Durability Index) kofunikira. Njira yosamala ndikuyamba kumapeto kwa mtundu wovomerezeka, kuyeza PDI ndi kWh/t, ndikuwonjezera CR pokhapokha ngati kulimba kuli pansi pa zomwe zafotokozedwa. 2.2 Chiŵerengero cha L/D ndi Geometry ya Mabowo Ngakhale CR imayang'anira kupsinjika konse, chiŵerengero cha L/D chimafotokoza momveka bwino makhalidwe a kukangana kwa kutuluka kwa dzenje la die. "Dziko" — gawo lomaliza lolunjika la dzenje lisanatuluke — ndi komwe kuphulika kwa pellet-die kumafika pachimake. Dziko lalitali kwambiri limapanga kutentha komwe kumatha kusungunula magawo amafuta, kuchepetsa mavitamini omwe amakhudzidwa ndi kutentha, ndikupanga ma pellet ofewa kapena osweka. Ma countersunk otuluka ndi njira yotsimikizika yotsukira. Mwa kukulitsa gawo lotulukira, kutalika kwa nthaka kogwira ntchito kumachepetsedwa popanda kusokoneza kutalika kwa compression mkati mwa die. Izi zimasunga kuchuluka kwa pellet pomwe zimachepetsa kukangana ndi kugwiritsa ntchito mphamvu. Opanga ma die otsogola tsopano amagwiritsa ntchito finite element analysis (FEA) kuti apereke chitsanzo cha kugawa kwa kupsinjika kudutsa patebulo la dzenje, kuonetsetsa kuti m'lifupi mwa nthiti pakati pa mabowo oyandikana ndi okwanira kupewa kusweka pansi pa katundu wambiri wa radial. 2.3 Gulu la Zinthu ndi Metallurgy Alloy yachitsulo imatsimikizira kukana kutopa, kukana dzimbiri, komanso kukhazikika kwa kutentha.

Kuti izi zitheke zimafuna kukonzedwa magawo ambiri pambuyo pobowola mfuti—njira yomwe imalekanitsa opanga olondola ndi ogulitsa zinthu. Kuzama kwa kuuma—mtunda kuchokera pamwamba pa dzenje mpaka pomwe kuuma kumatsika pansi pa zomwe zimagwiritsidwa ntchito—ndikofunikanso. Osachepera 3–5 mm ndi muyezo wa madiye omwe cholinga chake ndi kupukuta ndi kukonzanso. Kuzimitsa kwa vacuum, komwe kumagwiritsidwa ntchito kwambiri ndi opanga apamwamba, kumapangitsa kuuma kofanana kudzera mu gawo logwirira ntchito popanda kusweka komwe kumagwirizanitsidwa ndi njira zakale zolimbitsira induction. 2.5 Pattern ya Mabowo ndi Chiŵerengero cha Malo Otseguka Kapangidwe ka mabowo—kawirikawiri kosasunthika m'malo molunjika—kumakhudza chiŵerengero cha malo otseguka a die, chomwe chimatanthauzidwa ngati malo onse odutsa mabowo ogawidwa ndi malo onse ogwirira ntchito. Ma die amakono okhala ndi mphamvu zambiri amalimbana ndi chiŵerengero cha malo otseguka chopitilira 20%. Chiŵerengero chapamwamba chimalola zinthu zambiri kudutsa pa kuzungulira kulikonse, zomwe zimapangitsa kuti ntchito ya RPM ikhale yokwera popanda kutsekeka. Kusinthana ndi umphumphu wa kapangidwe kake. Mzere uliwonse wowonjezera wa mabowo umachepetsa m'lifupi mwa nthiti pakati pa mabowo oyandikana nawo. Mapangidwe obowola okonzedwa bwino a FEA amatsimikizira kuti kuchuluka kwa kupsinjika kuzungulira mabowo omangirira ndi kuzungulira kwa mkati mwa die kumakhalabe mkati mwa malire otetezeka. Izi si ukadaulo woyeserera ndi zolakwika; zimafuna kuyerekezera kwa makompyuta komwe kumaphatikizidwa mu ntchito yobowola ya CNC. 3. Chikhazikitso Chosankhidwa Choyendetsedwa ndi Ntchito Chikhazikitso chotsatirachi chimayika zofunikira pakugwiritsa ntchito ma specifications a die. Chimatengera mphero yokhazikika ya mphete (SZLH kapena MZLH series, kapena mitundu yofanana ya CPM/Andritz). 3.1 Chakudya cha Nkhuku ndi Nkhumba (ma pellets a 3–5 mm) – CR: 1:8 – 1:10 – Zipangizo: 4Cr13 Chitsulo chosapanga dzimbiri – M'mimba mwa dzenje: 3.0–4.5 mm – Zofunika kuziganizira: Kumaliza pamwamba ndikofunikira kwambiri—kuuma kulikonse kumateteza ku kuuma kwa chakudya komwe kumawonjezera kukhuthala ndikulimbikitsa kukula kwa mabakiteriya. Malo olowera a Chamfered amachepetsa kutsetsereka kwa roller ndikuwonjezera mphamvu yotuluka pa liwiro lokhazikika la mkombero. 3.2 Chakudya cha Ng'ombe ndi Zoweta (ma pellets a 6–8 mm) – CR: 1:10 – 1:15 – Zipangizo: 4Cr13 kapena X46Cr13 (kutengera kuchuluka kwa silika mu roughage) – M'mimba mwa dzenje: 6.0–8.0 mm – Zofunika kuziganizira: CR yapamwamba ndiyofunikira kuti zinthu zokhuthala zikhale zolimba. Ma outro aulere akulimbikitsidwa kuti achepetse kutentha komwe kumabwera chifukwa cha kukangana. 3.3 Kudyetsa Madzi (ma pellets a 1.5–4 mm, akumira ndi oyandama) – CR: 1:12 – 1:20 (chakudya choyandama chimafuna kupsinjika kwakukulu) – Zipangizo: X46Cr13 kapena alloy yapamwamba, chifukwa cha chinyezi chambiri komanso zowonjezera zowononga – M'mimba mwa dzenje: 1.5–4.0 mm – Zofunika kuziganizira: Kukhuthala kwa die kumawonjezeka kuti nthawi yokakamiza iwonjezere kukhuthala kwa starch. Kufanana kwa kuuma ndikofunikira kwambiri—mizere ya aquafeed nthawi zambiri imayenda maola 20–24 patsiku, zomwe zimapangitsa kuti moyo wa die ukhale wodziwika bwino wa OEE (Kugwira Ntchito Kwambiri kwa Zipangizo Zonse). 3.4 Ma Biomass / Ma Wood Pellets (6–8 mm) – CR: 1:6 – 1:12 – Zipangizo: X46Cr13 osachepera; alloy yapamwamba kwambiri yolimbikitsidwa ya mitundu ya silica yapamwamba – M'mimba mwa dzenje: 6.0–8.0 mm – Zofunika kuziganizira: Silika yamatabwa ndi yolimba kwambiri. Kukhuthala kwa die kumayikidwa patsogolo kuposa kuchuluka kwa mabowo kuti kukhale kwakukulu komanso kutentha. Ma inlet okhala ndi ma chamfer angles amphamvu amathandiza kuti zinthu ziziyenda m'dera lopanikizika. 4. Kuchokera ku Mafotokozedwe Ofunika Kupita ku Kupanga: Kukula kwa Kupanga Kusankha magawo olondola ndikofunikira, koma sikokwanira. Kusiyana pakati pa mafotokozedwe ndi magwiridwe antchito kumalumikizidwa ndi kulondola kwa kupanga. Masitepe atatu a ndondomeko ndi otsimikizika: Kulondola kwa kuboola mfuti. Mabowole a mfuti a CNC amakono amakwaniritsa kulolerana kwa malo a mabowo mkati mwa ± 0.02 mm ndikusunga mainchesi ofanana a mabowo kuzungulira die yonse. Kupatuka kumapangitsa kuyenda kosagwirizana kwa zinthu, kutentha kwambiri komwe kumachitika pamalopo, komanso kuwonongeka msanga. Kuchiza kutentha kwa vacuum.
