Izityalo ze-PET zokuphinda zisetyenziswe zinezinto ezininzi ezibalulekileyo zenkqubo ezidityaniswe yi-pneumatic kunye ne-mechanical transveying systems.Ixesha lokuphumla ngenxa yoyilo olubi lwenkqubo yokuhanjiswa, usetyenziso olungalunganga lwamacandelo, okanye ukungabikho kogcino akufuneki lube yinyani.Cela ngaphezulu.#Iindlela eziNgcono
Wonke umntu uyavuma ukuba ukuvelisa iimveliso ezivela kwi-PET esetyenzisiweyo (rPET) yinto enhle, kodwa ukuvelisa iindawo eziphezulu ezivela kwizinto ezibonakalayo ezingabonakaliyo, ezifana neebhotile ze-PET zasemva kwabathengi, akukho lula.Izixhobo zenkqubo eyinkimbinkimbi (umz. , i-extrusion, njl.) esetyenziswe kwizityalo ze-rPET ukufezekisa oku ifumene ingqwalasela eninzi - kwaye ngokufanelekileyo.Ngelishwa, iinkqubo zothutho ezihambisa izinto eziphathekayo phakathi kwesi sixhobo ngamanye amaxesha zongezwa njengengcamango, enokubangela ukuba ibe ngaphantsi kweyona nto ilungileyo. ukusebenza kwesityalo.
Kwi-PET yokuphinda isetyenziswe, yinkqubo yokuhambisa edibanisa onke amanyathelo enkqubo kunye - ngoko kufuneka iyilwe ngokukodwa le nto.
Ukugcina isityalo sakho sisebenza kuqala ngoyilo lwesityalo esisemgangathweni, kwaye ayizizo zonke izixhobo zokutshintshela ezenziwe ngokulinganayoScrew conveyorsezisebenze kakuhle kakhulu kwimigca yetshiphu kule minyaka ilishumi idlulileyo kungenzeka ukuba zibe ngaphantsi kwaye zisilele ngokukhawuleza kwimigca yeflake.Isixhobo sokuhambisa umoya esinokuhambisa i-10,000 lb/hr chips singakwazi ukuhambisa i-4000 lb/hr chips.Umgibe oqhelekileyo. ayilandeli izikhokelo zoyilo ngokukodwa ukuphatha imathiriyeli esetyenzisiweyo.
Isihambisi somoya esikwaziyo ukuhambisa iitshiphusi ze-10,000 lb/hr singakwazi ukuhambisa iitshiphusi ezingama-4000 lb/hr.
Eyona ngcamango isisiseko ekufuneka iqwalaselwe kukuba ubuninzi obuphantsi beebhotile ze-PET flakes kunciphisa umthamo wangempela wenkqubo yokudlulisa xa kuthelekiswa nobuninzi bezinto eziphathekayo zegranular. Amaphepha adla ngokuba makhulu kakhulu.Isikrufu sokuhambisa iitships zePET sinokuba sisiqingatha sobubanzi kwaye sisebenzise isibini esithathwini samandla enjini ye-screw conveyor eyenzelwe iiflakes. .Umbhobho kufuneka ube yi-31/2 intshi.segment.Ii-Solids ukuya kwi-gas ratios ukuya kwi-15: 1 ingasetyenziselwa ii-chips, kodwa kungcono ukusebenzisa iinkqubo ze-flake ezinomlinganiselo ophezulu we-5: 1.
Ngaba ungasebenzisa kwa isantya sokuthutha somoya esihambisayo ukwenzela iiflakes ukuphatha amasuntswana amile ngendlela efanayo? Hayi, isezantsi kakhulu ukufumana intshukumo yeflake engaqhelekanga. I-cone ye-flakes. Ngokuxhomekeke kubukhulu besitya sokugcina, kunokuba yimfuneko ukwenza i-silo isebenze ukuvumela iiflakes ukuba zihambe.Ininzi yale "mithetho" iphuhliswa ngokuzama kunye nephutha, ngoko kuxhomekeka kwiinjineli ezinamava okuyila iinkqubo ngokukodwa. iiflakes ze-rPET.
Ezinye iiglidants zemveli zesmbumbu eziqinileyo azonelanga iipilisi zebhotile.Isilo sesisele esiboniswe apha sincediswa sisikrufu esithambekileyo esaphula iibhulorho kwaye sikhuphe iiflakes kwisitshixo somoya esijikelezayo ukwenzela ukutya okuthembekileyo nozinzileyo kwinkqubo yokuhambisa umoya.
Uyilo olulungileyo lwenkqubo yokuhambisa aluqinisekisi ukuthembeka kwenkqubo.Ukufezekisa ukusebenza okuthembekileyo, amacandelo kwinkqubo yothutho kufuneka ayilwe ngokukodwa kwiiflakes ze-rPET.
Iivalve ezijikelezayo ezondla iiflakes kwinkqubo yokuhanjiswa koxinzelelo okanye nayiphi na enye inxalenye yenkqubo kufuneka ibe nzima-umthwalo wokumelana neminyaka yokuxhatshazwa ukusuka kwiiflakes ezingaqhelekanga kunye nazo zonke ezinye izinto ezingcolileyo ezidlula kuzo.Umsebenzi onzima wokuphoswa kwezindlu zensimbi ezingenasici kunye neerotors ngokuqinisekileyo zibiza. ngaphezu koyilo olucekethekileyo lwamaphepha esinyithi, kodwa iindleko ezongezelelweyo zihlawulelwa kukucuthwa kwexesha elincitshisiweyo kunye nokunciphisa iindleko zokubuyisela izixhobo.
Iiflake ze-PET ezisetyenzisiweyo ziyahluka kwii-PET flakes kwimilo yesuntswana okanye ubuninzi bobuninzi.Ikwayi-abrasive.
Iirotha kwiivalvu ezijikelezayo ezenzelwe i-lamella kufuneka zibe ne-V-shaped rotor kunye "nekhuba" kwindawo yokungena ukunciphisa ukukrazula kunye nokuvala. Iingcebiso eziguquguqukayo ngamanye amaxesha zisetyenziselwa ukoyisa imiba yokuqhaqha, kodwa ezi zifuna ukugcinwa rhoqo kwaye zingenise amaqhekeza amancinci amancinci inkqubo enokudala iingxaki ezantsi.
Ngenxa yobume be-abrasive of flakes, i-elbows kwiinkqubo zokuhambisa i-pneumatic yingxaki eqhelekileyo.Inkqubo yokuthutha i-sheet inesantya esiphezulu, kwaye i-sheet sliding ecaleni kwendawo yangaphandle ye-elbow iya kudlula kwi-tube yensimbi engenasici. ababoneleli banikezela ngeengqiniba ezikhethekileyo ezinciphisa le ngxaki, kwaye zisenokwenziwa ziikontraka ezingoomatshini.
Ukunxiba kwenzeka ngokugoba rhoqo kwiradiyasi emide njengoko izinto eziqinileyo ezirhawuzelayo zityibilika ecaleni komphezulu ongaphandle ngesantya esiphezulu.Qwalasela ukusebenzisa iigophe ezimbalwa kangangoko kunokwenzeka, kwaye mhlawumbi ukugoba okukhethekileyo okuyilelwe ukunciphisa oku kunxitywa.
Ukuqulunqa nokwenza isicwangciso sokulondoloza isixokelelwano sothutho somatshini linyathelo lokugqibela, njengoko kukho iindawo ezininzi ezihambayo ezidibana ngokuthe ngqo neeflakes ezingaqhelekanga kunye nongcoliseko.Ngelishwa, ulondolozo olucwangcisiweyo luhlala lungahoywa.
Ezinye ii-airlock ezijikelezayo zinezitywina ze-shaft ekufuneka ziqiniswe rhoqo ukuze zithintele ukuvuza.Khangela iivalve ezine-labyrinth shaft seals kunye neebheringi zangaphandle ezingadingi ukulungiswa rhoqo.Xa ezi zivalo zisetyenziselwa ukufakwa kwephepha, kudla ngokuyimfuneko ukucoca i-shaft. tywina ngesixhobo somoya esicocekileyo.Qinisekisa ukuba i-shaft seal yokucoca uxinzelelo ibekwe ngokuchanekileyo (ngokuqhelekileyo malunga ne-5 psig ngaphezu koxinzelelo oluphezulu lokuhambisa) kwaye umoya uhamba ngokwenene.
Iirotha zevalvu ezigugileyo zinokubangela ukuvuza okugqithisileyo kwiinkqubo zokuhanjiswa koxinzelelo olulungileyo. Oku kuvuza kunciphisa ubungakanani bomoya ogqithiselwayo kumbhobho, ngaloo ndlela kuncitshiswe umthamo opheleleyo wenkqubo. khangela isithuba phakathi kwencam ye-rotor kunye nezindlu rhoqo.
Ngenxa yomthwalo ophezulu wothuli, izihlungi zomoya zinokuvala ngokukhawuleza izityalo ze-rPET ngaphambi kokukhulula umoya ohambisayo ubuyele emoyeni.Qinisekisa ukuba i-gauge yoxinzelelo oluhlukeneyo lusebenza ngokufanelekileyo kwaye uqinisekise ukuba umqhubi uyayihlola rhoqo.Ukukhanya kakhulu kunye nothuli lwe-PET oluthambileyo luyakwazi ukuvala okanye ibhuloho yokuphuma komqokeleli, kodwa i-transmitter yezinga eliphezulu kwi-cone yokukhupha inokunceda ukufumanisa ezi zithintelo ngaphambi kokuba zibangele iingxaki ezinkulu.Qinisekisa ukuba ususa rhoqo uthuli olungaphakathi kwi-baghouse.
Eli nqaku alikwazi ukugubungela yonke imigaqo yesithupha yoyilo oluthembekileyo kunye nokugcinwa kweenkqubo zokudluliselwa kwizityalo ze-rPET, kodwa ngethemba ukuba uyaqonda ukuba kukho amanqaku amaninzi okuqwalasela kwaye akukho nto ithatha indawo yamava.Qwalasela ngokulandela iingcebiso zababoneleli bezixhobo abasebenza baye baphatha iiflakes ze-rPET kwixesha elidlulileyo.Aba bathengisi baye bahamba kulo lonke ulingo kunye nephutha, ngoko akufuneki ukuba uhambe nabo.
Malunga noMbhali: UJoseph Lutz unguMlawuli weNtengiso kunye neNtengiso yePelletron Corp.Uneminyaka eyi-15 yamava obugcisa ekuphuhliseni izisombululo zokuphatha izinto zeplastiki. I-lab yovavanyo.U-Lutz ugunyazise iinkqubo ezininzi zokuhambisa umoya kwihlabathi jikelele kwaye unikwe amalungelo awodwa abenzi beemveliso ezintathu ezintsha.
Itekhnoloji entsha, eya kuqala kwi-NPE kwinyanga ezayo, ilumkisa xa kufuneka ukugcinwa kokuthintela ngaphambi kokuba ukusilela kwezixhobo kuphazamise imveliso.
Xa kuthelekiswa neendleko zokuthenga i-resin enemibala yangaphambili okanye ukufaka i-high-capacity central mixer kwi-pre-mix resin kunye ne-masterbatch, umbala kumatshini unokubonelela ngeenzuzo zeendleko ezibalulekileyo, kubandakanywa iindleko zokunciphisa izinto eziphathekayo kunye nokunyuka kwenkqubo yokuguquguquka.
Kwiinkqubo zokuhambisa i-vacuum yokucubungula iiplastiki, izisombululo zokuphatha umgubo azisoloko zifunwa.Izisombululo ze-turnkey ezikhethiweyo zingaba yinto ekhethekileyo yokukhetha i-powders kunye ne-solids eninzi kuluhlu olubanzi lwamashishini.
