Izitshalo zokugaywa kabusha kwe-PET zinemishini eminingi ebalulekile yenqubo exhunywe amasistimu okuhambisa umoya nemishini.Isikhathi sokuphumula ngenxa yokuklanywa kabi kwesistimu yokudlulisela, ukusetshenziswa okungalungile kwezingxenye, noma ukuntuleka kokunakekelwa akufanele kube ngokoqobo.Cela okwengeziwe.#Imikhuba Engcono Kakhulu
Wonke umuntu uyavuma ukuthi ukukhiqiza imikhiqizo evela ku-PET (rPET) egaywe kabusha kuyinto enhle, kodwa ukukhiqiza izingxenye zekhwalithi ephezulu ezivela ezintweni eziluhlaza ezingahleliwe, njengamabhodlela e-PET athunyelwa ngabathengi, akulula.Imishini yenqubo eyinkimbinkimbi (isb. , extrusion, njll.) ezisetshenziswa ezitshalweni ze-rPET ukufeza lokhu zithole ukunakwa okukhulu - futhi kufanele.Ngeshwa, izinhlelo zokuthutha ezihambisa impahla phakathi kwalezi zisetshenziswa ngezinye izikhathi zengezwa njengokucatshangelwa kwangemuva, okungase kubangele ngaphansi kokuphelele okuphelele. ukusebenza kwezitshalo.
Emsebenzini wokubuyisela kabusha i-PET, isistimu yokudlulisa ehlanganisa zonke izinyathelo zenqubo ndawonye - ngakho kufanele yakhelwe le nto.
Ukugcina isitshalo sakho sisebenza kuqala ngesakhiwo sesitshalo sekhwalithi, futhi akuzona zonke izinto zokudlulisa ezenziwe zilinganaisikulufu conveyorsezisebenze kahle kakhulu emigqeni yama-chip kule minyaka eyishumi edlule kungenzeka zibe ngaphansi futhi zehluleke ngokushesha emigqeni ye-flake.Isihambisi somoya esikwazi ukuhambisa ama-chips angu-10,000 lb/hr singakwazi kuphela ukuhambisa ama-chips angu-4000 lb/hr.Umgodi ovamile ayilandeli imihlahlandlela yokudizayina ngqo yokuphatha izinto ezigaywe kabusha.
Isihambisi somoya esikwazi ukuhambisa ama-chips angu-10,000 lb/hr singakwazi kuphela ukuhambisa ama-chips angu-4000 lb/hr.
Umqondo oyisisekelo okufanele ucatshangelwe ukuthi ukuminyana okuphansi kwenqwaba yama-flakes ebhodlela le-PET kunciphisa umthamo wangempela wesistimu yokudlulisa uma kuqhathaniswa nobuningi obuphezulu bezinto ezibonakalayo. amashidi avamise ukuba makhulu kakhulu.I-screw conveyor yamachips e-PET ingaba uhhafu wobubanzi futhi isebenzise izingxenye ezimbili kwezintathu zamandla enjini yesixhumi esiyisikulufa esidizayinelwe ama-flakes.Isistimu yokudlulisa umoya womoya enganyakazisa chip engu-6000 lb/hr ngamayintshi angu-3. .Ipayipi idinga ukuba ngu-31/2 amayintshi.ingxenye.Izilinganiso eziqinile negesi ezifika ku-15:1 zingasetshenziselwa ama-chips, kodwa kungcono kakhulu ukusebenzisa amasistimu e-flake anesilinganiso esiphezulu esingu-5:1.
Ungakwazi yini ukusebenzisa isivinini esifanayo sokudlulisa umoya ukuze ubambe izinhlayiya ezimise ngendlela efanayo?Cha, liphansi kakhulu ukuze uthole ukunyakaza kwe-flake okungajwayelekile.Ebhokisini lokugcina, ikhoni engu-60° evumela izinhlayiya ukuthi zigeleze kalula kufanele ibe yinde engu-70° I-cone for flakes.Kuya ngosayizi wesiqukathi sokugcina, kungase kudingeke ukuthi isisele sisebenze ukuze ama-flakes ageleze.Iningi lale "mithetho" ithuthukiswa ngokuzama nangephutha, ngakho-ke thembela konjiniyela abanolwazi lokuklama izinqubo ngokukhethekile. ngamaflakes e-rPET.
Amanye ama-glidant endabuko enqwaba eqinile ayanele kumathebulethi amabhodlela.Indawo yokukhipha isisele eboniswe lapha isizwa isikulufu esithambekile esiphula amabhuloho futhi sikhiphe ama-flakes ku-airlock ezungezayo ukuze kutholakale ukudla okuthembekile nokuzinzile kusistimu yokudlulisa umoya.
Ukuklama okuhle kwesistimu yokudlulisa akuqinisekisi ukwethembeka kwesistimu.Ukufeza ukusebenza okuthembekile, izingxenye ohlelweni lwezokuthutha kufanele zakhelwe ngokuqondile ama-rPET flakes.
Ama-valve ajikelezayo afaka ama-flakes ohlelweni lokulethwa kwengcindezi noma iyiphi enye ingxenye yenqubo kufanele kube umsebenzi onzima ukuze amelane nokuhlukunyezwa iminyaka eminingi ngenxa yama-flakes angajwayelekile kanye nakho konke okunye ukungcola okudlula kuwo.Izindlu zensimbi engagqwali ezisindayo kanye nama-rotor abiza ngempela ngaphezu kwemiklamo yensimbi yeshidi elincanyana, kodwa izindleko ezengeziwe zikhokhiswa isikhathi sokuphumula esincishisiwe kanye nezindleko zokushintshwa kwehadiwe ezincishisiwe.
Amaflaki e-PET agaywe kabusha ahlukile kuma-PET flakes ngomumo wezinhlayiyana noma ukuminyana ngobuningi.
Ama-rotor kumavalvu ajikelezayo aklanyelwe i-lamella kufanele abe ne-rotor emise okuka-V kanye “negeja” endaweni yokungena ukuze kuncishiswe ukuqhekeka nokuvala. Amathiphu aguquguqukayo ngezinye izikhathi asetshenziselwa ukunqoba izinkinga zokuqhekeka, kodwa lawa adinga ukunakekelwa njalo futhi angenise izingcezu ezincane zensimbi phakathi. inqubo engadala izinkinga ezansi nomfula.
Ngenxa yokuluma kwama-flakes, izindololwane ezinhlelweni zokudlulisa umoya womoya ziyinkinga evamile.Isistimu yokuthutha amashidi inejubane eliphezulu uma kuqhathaniswa, futhi ishidi elislayida ngaphandle kwendololwane lizodlula epayipini lensimbi engagqwali yebanga le-10. abahlinzeki bahlinzeka ngezindololwane ezikhethekile ezinciphisa le nkinga, futhi zingakhiwa ngisho nosonkontileka abayimishini.
Ukugqokwa kwenzeka ezindaweni ezivame ukugoba engaba ngama-radius amade njengoba izinto eziqinile ezilumayo zishelela endaweni engaphandle ngesivinini esikhulu.Cabanga ukusebenzisa amagophe ambalwa ngangokunokwenzeka, kanye nokugoba okukhethekile okuklanyelwe ukunciphisa lokhu kuguga.
Ukwakha nokusebenzisa uhlelo lokulungisa uhlelo lokuthutha lwesitshalo kuyisinyathelo sokugcina, njengoba kunezingxenye eziningi ezihambayo ezithintana ngqo nama-flakes angavamile kanye nokungcola.Ngeshwa, ukugcinwa okuhleliwe ngokuvamile akunakwa.
Amanye ama-airlock ajikelezayo anezimpawu ze-shaft ezidinga ukuqiniswa njalo ukuze ugweme ukuvuza.Bheka ama-valve ane-labyrinth shaft seal kanye nama-outboard bearings angadingi ukulungiswa njalo. vala ngomoya wensimbi ohlanzekile.Qinisekisa ukuthi ukucindezela kwe-shaft seal purge kusethwe ngendlela efanele (imvamisa cishe ama-psig angu-5 ngaphezu kokucindezela okukhulu kokulethwa) nokuthi umoya uyageleza ngempela.
Ama-rotor ama-valve agugile angabangela ukuvuza ngokweqile ezinhlelweni zokulethwa kwengcindezi eqondile. Lokhu kuvuza kunciphisa inani lomoya odluliswayo epayipini, ngaleyo ndlela kunciphise umthamo wonkana wesistimu. hlola igebe phakathi kwephuzu le-rotor kanye nezindlu njalo.
Ngenxa yomthwalo ophakeme wothuli, izihlungi zomoya zingakwazi ukuvala ngokushesha izitshalo ze-rPET ngaphambi kokukhulula umoya odlulisayo ubuyele emkhathini.Qinisekisa ukuthi i-gauge yokuhlukanisa ingcindezi isebenza kahle futhi uqiniseke ukuthi opharetha uyayihlola njalo.Uthuli lwe-PET olulula kakhulu futhi oluthambile lungavala noma vala indawo yokuphuma komqoqi, kodwa isidlulisi esisezingeni eliphezulu ku-cone yokukhipha singasiza ekuboneni lokhu kuvinjelwa ngaphambi kokuba kubangele izinkinga ezinkulu.Qinisekisa ukuthi ususa njalo uthuli olungaphakathi endlini yesikhwama.
Lesi sihloko asikwazi ukuhlanganisa yonke imithetho yesithupha yokuklama nokugcinwa okuthembekile kwezinhlelo zokudlulisa ezitshalweni ze-rPET, kodwa ngethemba ukuthi uyaqonda ukuthi kunamaphuzu amaningi okufanele acatshangelwe nokuthi ayikho into engathatha indawo yesipiliyoni.Cabanga ngokulandela izincomo zabahlinzeki bemishini aba bake baphatha ama-rPET flakes esikhathini esidlule.Laba bathengisi badlule kukho konke ukuhlola namaphutha, ngakho-ke akumele nawe udlule kukho.
Mayelana Nombhali: UJoseph Lutz unguMqondisi Wezokuthengisa Nokumaketha we-Pelletron Corp. Uneminyaka engu-15 yokuhlangenwe nakho kobuchwepheshe ekuthuthukiseni izixazululo zokubamba izinto zepulasitiki ngobuningi. Umsebenzi wakhe e-Pelletron waqala e-R&D, lapho afunda khona ukuvela nokuphuma kwe-pneumatics endaweni yokusebenzela. Ilebhu yokuhlola.U-Lutz unikeze amasistimu amaningi okudlulisa umoya womoya emhlabeni jikelele futhi unikezwe amalungelo obunikazi amathathu emikhiqizo emisha.
Ubuchwepheshe obusha, obuzoqala ukusebenza e-NPE ngenyanga ezayo, buxwayisa uma ukugcinwa kokuvikela kudingeka ngaphambi kokuthi ukungasebenzi kwemishini kuphazamise ukukhiqizwa.
Uma kuqhathaniswa nezindleko zokuthenga i-resin enombala wangaphambili noma ukufaka i-mixer ephakathi nendawo yomthamo omkhulu ku-pre-mix resin kanye ne-masterbatch, ukufaka imibala emshinini kunganikeza izinzuzo zezindleko ezibalulekile, okuhlanganisa izindleko ezincishisiwe ze-inventory kanye nokwanda kokuguquguquka kwenqubo.
Kuzinhlelo zokuhambisa i-vacuum zokucubungula amapulasitiki, izixazululo zokuphatha i-powder ezenziwe ngokwezifiso azihlali zidingeka.Izixazululo ze-turnkey ezenziwe ngaphambili zingaba ukukhetha okuphelele kwama-powder kanye nokuqinile kwenqwaba ezinhlobonhlobo zezimboni.
