Izityalo ze-PET zokurisayikilisha zinezinto ezininzi ezibalulekileyo zenkqubo ezidityaniswe yi-pneumatic kunye ne-mechanical transveying systems.Ixesha lokuphumla ngenxa yoyilo olubi lwenkqubo yothumelo, usetyenziso olungachanekanga lwamacandelo, okanye ukungabikho kogcino akufuneki lube yinyani.Buza ngakumbi.#Iindlela eziNgcono
Wonke umntu uyavuma ukuba ukuvelisa iimveliso ezivela kwi-PET esetyenzisiweyo (i-rPET) yinto enhle, kodwa ukuvelisa iindawo eziphezulu ezivela kwizinto ezibonakalayo ezingabonakaliyo, ezifana neebhotile ze-PET ze-post-consumer, akukho lula.Izixhobo zenkqubo eyinkimbinkimbi (umzekelo, ukuhlelwa kwe-optical, i-filtration, extrusion, njl. ngamanye amaxesha kongezwa njengengcinga esemva, enokuthi ibe nesiphumo esingaphantsi komgangatho wokusebenza kwesityalo ngokubanzi.
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 ye-chip kule minyaka ilishumi idlulileyo zinokuthi zibe ngaphantsi kwaye zingaphumeleli ngokukhawuleza kwimigca ye-flake.Umthumeli we-pneumatic onokuhambisa i-chips ze-10,000 lb / hr unokukwazi ukuhambisa i-chips 4000 lb / hr.I-pitfall eqhelekileyo ayilandeli izikhokelo zoyilo ngokukodwa ukuphatha izinto ezisetyenzisiweyo.
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 beeflakes zebhotile ze-PET bunciphisa amandla okwenene enkqubo yokudluliselwa xa kuthelekiswa nobuninzi bobuninzi bezinto eziphathekayo zegranular. Iiflake nazo aziqhelekanga ngokwemilo. Oku kuthetha ukuba izixhobo zokulungisa amaphepha zidla ngokuba zikhulu. inokuhambisa i-chip ye-6000 lb / hr ngokusebenzisa i-intshi ezi-3. Umbhobho kufuneka ube yi-31/2 intshi.
Ngaba ungasebenzisa isantya somoya esihambisayo esifana nesokuba iiflakes ukuphatha amasuntswana amile ngendlela efanayo? Hayi, iphantsi kakhulu ukufumana intshukumo yeflake engaqhelekanga.Kwibhokisi yokugcina, i-cone ye-60 ° evumela amasuntswana ukuba ahambe ngokulula kufuneka ibe yi-cone emde ye-70 ° ye-flakes.Kuxhomekeke kubungakanani besikhongozeli sogcino, kunokuba yimfuneko ukuqukuqela kwe-siloles "i-flakes" ivumela ukuba i-siloles isebenze. ziphuhliswa ngolingo kunye nempazamo, ke thembela kwiinjineli ezinamava okuyila iinkqubo ezikhethekileyo ze-rPET flakes.
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 nokuzinzileyo kwi-pneumatic transveying system.
Uyilo olulungileyo lwenkqubo yokuhambisa aluqinisekisi ukuthembeka kwenkqubo.Ukufezekisa ukusebenza okuthembekileyo, amacandelo kwinkqubo yothutho kufuneka ayilwe ngokukodwa kwiiflakes ze-rPET.
Iivalve ezijikelezayo ezondla ama-flakes kwinkqubo yokunikezelwa koxinzelelo okanye nayiphi na enye inxalenye yenkqubo kufuneka ibe nzima-umsebenzi wokumelana neminyaka yokuxhatshazwa ukusuka kwiiflakes ezingaqhelekanga kunye nazo zonke ezinye izinto ezingcolileyo ezidlula kuzo.Izindlu ezinqabileyo ezinqabileyo ezifakwe kwi-stainless steel stainless kunye ne-rotors ngokuqinisekileyo zibiza ngaphezu kwe-thinner sheet sheet designs, kodwa iindleko ezongezelelweyo zichithwa ngokunciphisa ixesha lokunciphisa kunye nokunciphisa iindleko zokutshintshwa kwe-hardware.
Iiflake ze-PET ezisetyenzisiweyo ziyohluka kwii-PET flakes kwimilo yamasuntswana okanye ubuninzi bobuninzi.
I-Rotors kwi-valve ejikelezayo eyenzelwe i-lamella kufuneka ibe ne-V-shaped rotor kunye "nekhuba" kwindawo yokungena ukunciphisa i-shredding kunye ne-clogging.Iingcebiso eziguquguqukayo ngamanye amaxesha zisetyenziselwa ukunqoba imiba yokuqhawula, kodwa ezi zifuna ukugcinwa rhoqo kwaye zingenise iziqwenga zetsimbi ezincinci kwinkqubo enokudala iingxaki ezantsi.
Ngenxa yobume be-abrasive of flakes, i-elbows kwii-pneumatic transveying systems ziyingxaki eqhelekileyo.I-sheet transport system inesantya esiphezulu, kwaye i-sheet sliding ecaleni kwendawo yangaphandle ye-elbow iya kudlula kwi-tube ye-stainless steel stainless grade 10. Ababoneleli abahlukeneyo banikezela ngeengqiniba ezikhethekileyo ezinciphisa le ngxaki yekhontrakthi, kwaye inokunciphisa le ngxaki.
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-airlocks ezijikelezayo zinezitywina ze-shaft ezifuna ukuqiniswa rhoqo ukuphepha ukuvuza.Khangela iivalve ezine-labyrinth shaft seals kunye neebheringi zangaphandle ezingadingi ukugcinwa rhoqo.Xa ezi zivalo zisetyenziselwa ukusetyenziswa kwephepha, kudla ngokuyimfuneko ukucoca isitywina se-shaft ngesixhobo somoya esicocekileyo.Qinisekisa ukuba i-shaft seal yokucoca i-shaft seal ibekwe ngokuchanekileyo i-5 ephezulu yokuhambisa umoya kwaye ngokwenene uxinzelelo lusekwe ngokuchanekileyo ukuhanjiswa kwe-5 equkuqelayo.
Iirotha zevalve ezigugileyo zinokubangela ukuvuza okugqithisileyo kwiinkqubo zokuhanjiswa koxinzelelo olulungileyo.Oku kuvuza kunciphisa ubungakanani bomoya ogqithisiweyo kumbhobho, ngaloo ndlela kuncitshiswe umthamo opheleleyo wenkqubo.Inokubangela imiba yokuvalwa kwe-hopper ngaphezulu kwe-airlock ejikelezayo, ngoko jonga umsantsa phakathi kwencam yerotor kunye nendlu rhoqo.
Ngenxa yomthwalo ophezulu wothuli, izihlungi zomoya zinokuvala ngokukhawuleza izityalo ze-rPET ngaphambi kokukhulula umoya ohambisayo ubuyele kwi-atmosphere.Qinisekisa ukuba i-gauge yoxinzelelo oluhlukeneyo lusebenza ngokufanelekileyo kwaye uqinisekise ukuba umqhubi uyayihlola rhoqo.Ukukhanya kakhulu kunye nothuli lwe-PET olunobunkunkqele luyakwazi ukuvala okanye ukuvala i-outlet yomqokeleli, kodwa i-transmitter yezinga eliphezulu kwi-discharge ye-transmitter kwi-discharge ye-dischargement kwi-atmosphere. ukwakhiwa kothuli ngaphakathi kwe-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 abaye baphatha i-rPET flakes kwixesha elidlulileyo.Aba bathengisi baye bahamba kulo lonke uvavanyo kunye nephutha, ngoko ke akufanele uhambe nabo.
Malunga noMbhali: UJoseph Lutz unguMlawuli weNtengiso kunye neNtengiso yePelletron Corp.Uneminyaka eyi-15 yamava obugcisa ekuphuhliseni iplastiki eninzi yokuphatha izinto eziphathekayo.Umsebenzi wakhe ePelletron waqala kwi-R & D, apho wafunda khona i-ins kunye nokuphuma kwe-pneumatics kwi-lab yokuvavanya.U-Lutz uye wagunyazisa ezininzi iinkqubo zokuhambisa umoya we-pneumatic ziye zanikezelwa emhlabeni jikelele kunye neenkqubo ezintsha zokuhambisa imveliso emhlabeni jikelele.
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.
