Zomera zobwezeretsanso PET zimakhala ndi zida zambiri zofunika kwambiri zolumikizidwa ndi ma pneumatic and mechanical conveying systems.Kutsika chifukwa cha kusamalidwa bwino kwa dongosolo lopatsirana, kugwiritsa ntchito molakwika kwa zigawo, kapena kusowa kosamalira sikuyenera kukhala zenizeni.Pemphani zambiri.#Best Practices
Aliyense amavomereza kuti kupanga zinthu zopangidwa kuchokera ku PET (rPET) zobwezerezedwanso ndi chinthu chabwino, koma kupanga zida zapamwamba kuchokera kuzinthu zopangira mwachisawawa, monga mabotolo a PET ogula, sikophweka. , extrusion, etc.) zomwe zimagwiritsidwa ntchito muzomera za rPET kuti zikwaniritse izi zalandira chidwi kwambiri - ndipo moyenerera. ntchito ya zomera.
Mu ntchito yobwezeretsanso PET, ndi njira yotumizira yomwe imagwirizanitsa masitepe onse pamodzi - kotero iyenera kupangidwira makamaka pazinthu izi.
Kusunga mbewu yanu ikuyenda kumayamba ndi kapangidwe kabwino ka mbewu, ndipo si zida zonse zosinthira zomwe zimapangidwa mofananawononga conveyorszomwe zagwira ntchito bwino kwambiri pamizere ya chip m'zaka khumi zapitazi zikhoza kukhala zochepa kwambiri ndipo zimalephera mwamsanga pa mizere ya flake. Chotengera cha pneumatic chomwe chimatha kusuntha tchipisi ta 10,000 lb/hr chikhoza kusuntha tchipisi 4000 lb/hr. satsatira malangizo a kamangidwe kake kakugwira ntchito zobwezerezedwanso.
Chonyamula mpweya chomwe chimatha kusuntha tchipisi 10,000 lb/hr chikhoza kusuntha tchipisi ta 4000 lb/hr.
Lingaliro lofunika kwambiri loti muganizirepo ndiloti kuchepa kwakukulu kwa ma flakes a botolo la PET kumachepetsa mphamvu yeniyeni ya kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake. mapepala nthawi zambiri amakhala aakulu kwambiri. Chodulira chopondera cha tchipisi cha PET chikhoza kukhala theka la m'mimba mwake ndikugwiritsa ntchito magawo awiri pa atatu a mphamvu ya injini ya wononga wononga yopangira ma flakes. .Chitoliro chiyenera kukhala 31/2 mainchesi.segment.Zolimba ku gasi ziwerengero za 15: 1 zingagwiritsidwe ntchito tchipisi, koma ndi bwino kugwiritsa ntchito machitidwe a flake ndi chiŵerengero chachikulu cha 5: 1.
Kodi mungagwiritse ntchito liwiro lomweli la 60 ° lonyamula ma flakes kuti mugwire tinthu tating'ono tofanana? Ayi, ndikotsika kwambiri kuti musamayende bwino. M'bokosi losungiramo, koni ya 60 ° yomwe imalola kuti tinthu tiziyenda mosavuta iyenera kukhala yayitali 70° Kutengera ndi kukula kwa chidebe chosungirako, pangafunike kuyambitsa silo kuti ma flakes ayende.Zambiri mwa "malamulo" awa amapangidwa kudzera mukuyesera ndi zolakwika, kotero dalirani mainjiniya omwe ali ndi chidziwitso chopanga njira makamaka. kwa rPET flakes.
Ma glidants ena akale a zolimba zambiri sakwanira pamapiritsi a mabotolo. Chotulutsira silo chomwe chikuwonetsedwa apa chimathandizidwa ndi wononga milatho ndi kutulutsa ma flakes mu chotsekera cha airlock kuti adyetse odalirika ndi okhazikika mu makina otumizira mpweya.
Kapangidwe kabwino ka kachitidwe kotumizira sikumatsimikizira kudalirika kwa dongosolo.Kuti mukwaniritse magwiridwe antchito odalirika, zigawo zamayendedwe amayendedwe ziyenera kupangidwira makamaka ma rPET flakes.
Ma valve ozungulira omwe amadyetsa flakes mu dongosolo loperekera mphamvu kapena gawo lina lililonse la ndondomekoyi ayenera kukhala wolemetsa kwambiri kuti athe kulimbana ndi nkhanza kwa zaka zambiri kuchokera ku flakes osakhazikika ndi zonyansa zina zonse zomwe zimadutsamo. kuposa zojambula zachitsulo zocheperako, koma mtengo wowonjezera umachepetsedwa ndi kuchepetsedwa kwa nthawi yocheperako komanso kutsika mtengo kwa hardware.
Ma flakes a PET obwezerezedwanso amasiyana ndi ma flakes a PET mu mawonekedwe a tinthu kapena kuchuluka kwake.
Ma rotor okhala ndi ma valve ozungulira opangira lamella ayenera kukhala ndi chozungulira chofanana ndi V ndi "khasu" polowera kuti achepetse kung'ambika ndi kutsekeka.Nsonga zosinthika nthawi zina zimagwiritsidwa ntchito kuthana ndi zovuta zopukutira, koma izi zimafunikira kusamalidwa kosalekeza komanso kuyambitsa tizidutswa tating'ono tachitsulo mkati. njira yomwe ingayambitse mavuto kumtunda.
Chifukwa cha abrasive chikhalidwe cha flakes, elbows mu kachitidwe pneumatic conveying ndi vuto wamba.The pepala zoyendera dongosolo ali ndi liwiro lalitali, ndi pepala kutsetsereka pamwamba pa kunja kwa chigongono adzadutsa kalasi 10 zosapanga dzimbiri chubu. ogulitsa amapereka ma elbows apadera omwe amachepetsa vutoli, ndipo amatha kupangidwa ndi opanga makina.
Kuvala kumachitika pamapindika opindika atalitali ngati zolimba zomangira zimatsetsereka panja pa liwiro lalikulu. Lingalirani kugwiritsa ntchito mapindikira ochepa momwe mungathere, ndipo mwina mapindika apadera opangidwira kuchepetsa kuvala uku.
Kupanga ndi kuchita ndondomeko yokonza makina oyendetsa galimoto ndi gawo lomaliza, chifukwa pali zigawo zambiri zosuntha zomwe zimakumana ndi ma flakes osakhazikika komanso kuipitsidwa.
Ma airlocks ena ozungulira amakhala ndi zisindikizo za shaft zomwe zimafunika kumangirizidwa nthawi zonse kuti zisawonongeke.Fufuzani ma valve okhala ndi labyrinth shaft seals ndi mabere akunja omwe safuna kukonzanso nthawi zonse.Ma valvewa akagwiritsidwa ntchito pa pepala, nthawi zambiri amafunika kuyeretsa shaft. kusindikiza ndi mpweya wa chida choyera. Onetsetsani kuti shaft seal purge pressure imayikidwa bwino (kawirikawiri pafupifupi 5 psig pamwamba pa kuthamanga kwakukulu kopereka) komanso kuti mpweya ukuyenda.
Kutayikiraku kumachepetsa kuchuluka kwa mpweya womwe umatumizidwa munjira, motero kumachepetsa mphamvu yonse ya system.Itha kuyambitsanso zovuta zolumikizira ndi hopper pamwamba pa airlock yozungulira, kotero fufuzani kusiyana pakati pa nsonga ya rotor ndi nyumba nthawi zonse.
Chifukwa cha katundu wambiri wa fumbi, zosefera za mpweya zimatha kutseka mwamsanga zomera za rPET musanatulutse mpweya wobwerera kumlengalenga. Onetsetsani kuti kusiyana kwa mphamvu yamagetsi ikugwira ntchito bwino ndipo onetsetsani kuti woyendetsa akuyang'ana nthawi zonse.Fumbi la PET lopepuka kwambiri komanso lopanda phokoso limatha kutseka kapena mlatho kutulukira kwa otolera, koma mkulu mlingo wopatsira mu zotuluka chulucho angathandize kuzindikira blockages pamaso pa mavuto aakulu. Onetsetsani kuti nthawi zonse kuchotsa fumbi buildup mkati baghouse.
Nkhaniyi siingathe kulongosola malamulo onse a ndondomeko yodalirika ya mapangidwe odalirika ndi kukonza machitidwe otumizira mu zomera za rPET, koma mwachiyembekezo mukumvetsa kuti pali mfundo zambiri zomwe muyenera kuziganizira komanso kuti palibe cholowa m'malo mwa zochitika.Ganizirani motsatira malingaliro a ogulitsa zipangizo adagwirapo ma flakes a rPET m'mbuyomu.Ogulitsa awa adutsa mayesero onse ndi zolakwika, kotero simukuyenera kudutsa nawonso.
Zokhudza Wolemba: Joseph Lutz ndi Mtsogoleri wa Zogulitsa ndi Kutsatsa kwa Pelletron Corp.Ali ndi zaka 15 zaukadaulo popanga njira zothetsera mavuto apulasitiki. kuyesa lab.Lutz wapereka makina ambiri otumizira mpweya padziko lonse lapansi ndipo wapatsidwa ma patent atatu atsopano.
Ukadaulo watsopano, womwe udzayambike ku NPE mwezi wamawa, umachenjeza pakafunika kukonza zodzitchinjiriza zida zisanachitike kusokoneza kupanga.
Poyerekeza ndi mtengo wogula utomoni wamtundu wakale kapena kuyika chosakaniza chapakati chapamwamba kuti chisakanize utomoni ndi masterbatch, utoto pamakina ukhoza kupereka phindu lalikulu lamtengo wapatali, kuphatikiza kutsika mtengo kwazinthu komanso kusinthasintha kwazinthu.
Kwa makina opangira vacuum pokonza mapulasitiki, njira zogwiritsira ntchito ufa wokhazikika sizimafunika nthawi zonse.Mayankho a turnkey okonzedweratu akhoza kukhala chisankho chabwino cha ufa ndi zolimba zambiri m'mafakitale osiyanasiyana.
