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 ezingahleliwe ezingahleliwe, njengamabhodlela e-PET athunyelwa ngabathengi, akulula.Imishini yenqubo eyinkimbinkimbi (isb. ukuhlunga optical, filtration, extrusion, njll.) esetshenziswa ezitshalweni ze-rPET ukuze kuzuzwe lokhu kuthola ukunakwa okuningi, futhi le mishini yokuthutha ihambisa ngokufanele. ngesinye isikhathi kwengezwa njengokucatshangelwa kwangemuva, okungaholela ekusebenzeni kwezitshalo okungaphansi kokwanele okuphelele kukonke.
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 ye-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 awulandeli imihlahlandlela yokuklama ngokukhethekile ukuphatha 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 nokuminyana okuphezulu kwenqwaba yezinto ze-granular. Ama-flakes nawo anesimo esingajwayelekile. Lokhu kusho ukuthi izinto zokusebenza zokucubungula amashidi ngokuvamile zinkulu impela. inganyakazisa i-chip engu-6000 lb/hr ngamayintshi angu-3. Ipayipi idinga ukuba yi-31/2 amayintshi.ingxenye.Izilinganiso eziqinile kuya kwegesi 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 ukuthola ukunyakaza kwe-flake okungajwayelekile.Ebhokisini lokugcina, ikhoni engu-60° evumela izinhlayiya ukuthi zigeleze kalula kufanele ibe yi-cone ende engu-70° yama-flakes. Kuye ngosayizi wesiqukathi sokugcina, kungase kudingeke ukuthi ama-siloles ageleze ukuze asebenze. athuthukiswa ngokuzama nangephutha, ngakho-ke thembela konjiniyela abanolwazi lokuklama izinqubo eziqondene ngqo nama-rPET flakes.
Amanye ama-glidants endabuko okuqina kwenqwaba awanele kumathebulethi amabhodlela.Indawo yesisele 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 aphakela ama-flakes ohlelweni lokulethwa kwengcindezi noma iyiphi enye ingxenye yenqubo kufanele kube umsebenzi osindayo ukuze amelane nokuhlukumeza iminyaka eminingi kusuka kuma-flakes angajwayelekile kanye nakho konke okunye ukungcola okudlula kuwo.Izindlu zensimbi engagqwali ezisindayo kanye nama-rotor zibiza ngaphezu kwemiklamo yeshidi elincane lensimbi, kodwa izindleko ezengeziwe zikhokhiswa izindleko ezincishisiwe zokushintshwa kwe-hardware.
Amaflaki e-PET agaywe kabusha ahlukile kuma-PET flakes ngomumo wezinhlayiyana noma ukuminyana ngobuningi.
Ama-rotor kuma-valve ajikelezayo aklanyelwe i-lamella kufanele abe ne-rotor emise okwe-V kanye "negeja" endaweni yokungena ukuze kuncishiswe ukuhlakazeka nokuvala.Amathiphu aguquguqukayo ngezinye izikhathi asetshenziselwa ukunqoba izinkinga zokugaya, kodwa lezi zidinga ukunakekelwa njalo futhi futhi zethule izingcezu zensimbi ezincane enkambweni engadala izinkinga ezansi nomfula.
Ngenxa yokuqina kwama-flakes, izindololwane ezinhlelweni zokudlulisa umoya womoya ziyinkinga evamile.Isistimu yokuthutha amashidi inesivinini esikhulu uma kuqhathaniswa, futhi ishidi elishelelayo endaweni engaphandle yendololwane lizodlula epayipini lensimbi engagqwali yebanga le-10. Abahlinzeki abahlukahlukene banikeza izindololwane ezikhethekile ezinciphisa le nkinga yezinkontileka ezenziwe ngomshini.
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 ukunakekelwa okuvamile.Lapho lawa ma-valve esetshenziswa ekufakweni kweshidi, ngokuvamile kuyadingeka ukuthi kuhlanzwe uphawu lwe-shaft ngomoya wensimbi ohlanzekile.Qinisekisa ukuthi i-shaft seal yokuhlanza i-shaft seal isethwe ngendlela efanele (ikakhulukazi ingcindezi yomoya imayelana nokulethwa kwe-5) empeleni imayelana nokulethwa kwe-psig egelezayo.
Ama-rotor e-rotary valve agugile angabangela ukuvuza ngokweqile ezinhlelweni zokulethwa kwengcindezi enhle.Lokhu kuvuza kunciphisa inani lomoya odluliswayo epayipini, ngaleyo ndlela kunciphise umthamo wesistimu.
Ngenxa yomthwalo ophakeme wothuli, izihlungi zomoya zingakwazi ukuvala ngokushesha izitshalo ze-rPET ngaphambi kokukhulula umoya odlulisayo emuva emkhathini.Qinisekisa ukuthi igeji yokucindezela ehlukile isebenza kahle futhi uqiniseke ukuthi opharetha uyayihlola njalo.Uthuli lwe-PET olulula kakhulu futhi oluthambile lungakwazi ukuvala noma ukuvala i-outlet yomqoqi, kodwa i-transmitter yezinga eliphezulu ekukhipheni ngaphambi kokuba ikhiphe lezi zinkinga eziqinisekisa ukuthi i-blockage ingasiza ukusula lezi zinkinga eziqinisekisayo. ukunqwabelana kothuli ngaphakathi kwe-baghouse.
Lesi sihloko asikwazi ukuhlanganisa yonke imithetho yesithupha yokuklama nokugcinwa okuthembekile kwezinhlelo zokudlulisa ezitshalweni ze-rPET, kodwa ngethemba ukuthi uyaqonda ukuthi kunamaphuzu amaningi okufanele icatshangelwe nokuthi ayikho into engathatha indawo yesipiliyoni.Cabanga ngokulandela izincomo zabahlinzeki bemishini abaye baphatha ama-rPET flakes esikhathini esidlule.Laba bathengisi baye badlula kukho konke ukuhlola nephutha, ngakho-ke akudingekile ukuba udlule kukho.
Mayelana Nombhali: UJoseph Lutz unguMqondisi Wezokuthengisa Nokumaketha we-Pelletron Corp.Uneminyaka engu-15 yokuhlangenwe nakho kobuchwepheshe ekuthuthukiseni izixazululo zokuphatha izinto ezibonakalayo zepulasitiki.Umsebenzi wakhe e-Pelletron waqala e-R&D, lapho afunda khona ukungena nokuphuma kwe-pneumatics endaweni yokuhlola.U-Lutz ugunyaze amasistimu amaningi wokudlulisa umoya womoya futhi anikezwe amasistimu amasha anikezwe amatende emhlabeni jikelele.
Ubuchwepheshe obusha, obuzoqala ukusebenza e-NPE ngenyanga ezayo, buxwayisa uma ukugcinwa kokuvikela kuyadingeka 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.
