PET recycling zvirimwa zvine zvakawanda zvakakosha zvekugadzirisa midziyo yakabatana nepneumatic uye mechanical conveying systems.Kunonoka nekuda kwemaitiro asina kunaka ekufambisa hurongwa, kushandiswa kusina kururama kwezvikamu, kana kushayikwa kwekugadzirisa hakufaniri kuva chokwadi.Bvunza zvimwe.#Best Practices
Munhu wose anobvumirana kuti kugadzira zvigadzirwa kubva kuPET (rPET) chinhu chakanaka, asi kugadzira zvikamu zvepamusoro-soro kubva kune zvakasvibiswa zvakasvibiswa, zvakadai semabhodhoro e-post-consumer PET, hazvisi nyore.Iyo yakaoma nzira yekugadzira michina (eg optical sorting, filtration, extrusion, etc.) inoshandiswa muRPET zvirimwa kuti zvibudirire izvi zvakagamuchira zvakanyanya kutarisisa, uye zvigadziriso zvekutakura zviri nyore. dzimwe nguva inowedzerwa sekufunga kwekupedzisira, izvo zvinogona kuguma zvishoma pane zvakakwana zvakakwana kuita kwechirimwa.
Mukuita kwePET kudzokorodza kushanda, ndiyo nzira yekufambisa inosunga matanho ese pamwechete - saka inofanirwa kugadzirwa zvakanangana nechinhu ichi.
Kuchengeta chirimwa chako chichimhanya chinotanga nemhando yekugadzira dhizaini, uye haisi yese yekutamisa michina inogadzirwa yakaenzana.Thescrew conveyorsiyo yakashanda zvakanaka pamitsetse ye chip mumakore gumi apfuura inogona kunge yakaderera uye inokundikana nokukurumidza pamitsara yeflake.A pneumatic conveyor inogona kufambisa 10,000 lb / hr chips inogona kungokwanisa kufambisa 4000 lb / hr chips.Chikafu chinowanzoitika hachisi kutevera mazano ekugadzira zvakananga pakubata zvinhu zvakashandiswa zvakare.
Pneumatic conveyor inokwanisa kufambisa 10,000 lb/hr machipisi inogona chete kufambisa 4000 lb/hr machipisi.
Iro zano rekutanga rekufunga nderekuti iyo yakaderera yakawanda density yePET bhodhoro flakes inoderedza chaiyo kugona kweiyo dhizaini yekufambisa kana ichienzaniswa neakakwira yakawanda density yegranular materials.Maflakes zvakare anowedzera kusarongeka muchimiro.Izvi zvinoreva kuti midziyo yekugadzira mapepa inowanzove yakakura.A screw conveyor yePET chips inogona kunge iri hafu yedhayamita uye inoshandisa maviri-thitatu eiyo dhizaini dhizaini yekufambisa magetsi. inogona kufambisa 6000 lb / hr chip kuburikidza nemasendimita 3. Pipe inoda kuva 31/2 inches.segment.Solids kune gasi reshisheni inosvika 15: 1 inogona kushandiswa machipisi, asi zviri nani kushandisa maflake masisitimu ane huwandu hwakawanda hwe5: 1.
Unogona here kushandisa sipidhi yepickup yemhepo yakafanana kuti ubate zvimedu zvakaumbwa zvakafanana?Kwete, yakadzikira zvakanyanya kuti ukwanise kufamba zvisina kujairika. Mubhokisi rekuchengetera, 60° koni inobvumira kuti zvidimbu zviyerere zviri nyore inofanira kunge yakareba 70° koni yemaflakes. Zvichienderana nehukuru hwemudziyo wekuchengetera, zvingave zvakafanira kuti siloles iite kuti siloles ishande. inogadzirwa kuburikidza nekuyedza uye kukanganisa, saka vimba nevainjiniya vane ruzivo rwekugadzira maitirwo akanangana nerPET flakes.
Zvimwe zvinopenya zvechinyakare zvezvakaoma zvakawanda hazvikwani mahwendefa emabhodhoro.Silo yekubuda nayo inoratidzwa pano inobatsirwa nesiruu yakarerekera inopwanya mabhiriji uye inoburitsa maflakes muchivharo chemhepo chinotenderera kuitira kudya kwakavimbika uye kwakagadzikana kupinda mumhepo inofambisa mweya.
Yakanaka yekufambisa sisitimu dhizaini haivimbisi kuvimbika kwehurongwa.Kuwana kuita kwakavimbika, zvikamu zviri muhurongwa hwekutakura zvinofanirwa kunyatsogadzirirwa rPET flakes.
Mavharuvhu anotenderera anodyisa maflakes muhurongwa hwekumanikidza dhizaini kana chero imwe chikamu cheiyo nzira inofanirwa kuve inorema-basa kutsungirira makore ekushungurudzwa kubva kune zvisina kujairika flakes uye zvimwe zvese zvinosvibisa zvinopfuura mazviri.Heavy-duty cast stainless steel housing uye rotors zvechokwadi inodhura kupfuura yakaonda mapepa esimbi magadzirirwo, asi mari yakawedzerwa inogadziriswa nekuderedza nguva yekudzikisa uye kuderedzwa kwekugadzirisa hardware mari.
Akadzokororwazve PET maflakes anosiyana kubva kuPET flakes mune particle shape kana bulk density.Iyo zvakare abrasive.
Rotor mumavharuvhu anotenderera akagadzirirwa lamella anofanira kuva neV-shaped rotor uye "gejo" mune inlet kuderedza shredding uye kuvhara.Mazano anochinja dzimwe nguva anoshandiswa kukunda nyaya dzekucheka, asi izvi zvinoda kugara zvichigadziriswa uye zvinounzawo zvimedu zviduku zvesimbi mukugadzirisa zvinogona kukonzera matambudziko pasi pemvura.
Nekuda kwekukaruka kwemaflakes, magokora ari mupneumatic conveying system idambudziko rinowanzoitika. Iyo sheet transport system ine kukurumidza kukurumidza, uye jira rinotsvedza richitevedza kunze kwegokora richapfuura nepakati pegiredhi regumi resimbi isina tsvina chubhu.
Kupfeka kunoitika pamakona akareba eradius sezvimedu zvinokwenya zvinotsvedza zvichitevedza pamusoro pekunze zvine spidhi.Funga kushandisa mabhende mashoma sezvinobvira, uye pamwe mabhendi akakosha akagadzirirwa kuderedza kusakara uku.
Kugadzira nekuita hurongwa hwekugadzirisa kweplant's conveyor system ndiyo danho rekupedzisira, sezvo kune zvakawanda zvinofamba zvikamu zvinosangana zvakananga nemaflakes asina kujairika uye kusvibiswa.Sezvineiwo, kugadzirisa kwakarongwa kunowanzo furatirwa.
Mamwe mavharuvhu anotenderera ane shaft zvisimbiso zvinoda kugara zvakasimbiswa kuti zvirege kudonha.Tsvaga mavharuvhu ane labyrinth shaft seals uye outboard bearings izvo zvisingadi kugadziridzwa nguva dzose.Apo mavharuvhu aya anoshandiswa mumashizha ekushandiswa, zvinowanzodiwa kuchenesa shaft chisimbiso nemhepo yakachena yemudziyo.Iva nechokwadi chokuti shaft seal purge pressure inogadzika pamusoro pepamusoro pe5 mhepo uye chaizvoizvo kumanikidzwa kwepsig pamusoro pemhepo yakanyatsogadziriswa. kuyerera.
Yakasakara rotary valve rotors inogona kukonzera yakawandisa kudonha mune yakanaka yekumanikidza kuburitsa masisitimu.Kudonha uku kunoderedza huwandu hwemhepo inofambiswa mugomba, nekudaro ichideredza huwandu hwese hwehurongwa.Inogonawo kukonzera nyaya dzemabridging nehopper pamusoro peiyo rotary airlock, saka tarisa gap pakati peiyo rotor tip uye imba nguva dzose.
Nekuda kwekuremerwa kweguruva, mafirita emhepo anogona kukurumidza kuvhara rPET zvirimwa asati aburitsa mhepo inodzosera kumashure mumhepo.Iva nechokwadi chekusiyanisa gauge yekumanikidza iri kushanda nemazvo uye iva nechokwadi chekuti opareta anoiongorora nguva dzose.Chakanyanya kujeka uye fluffy PET guruva rinogona kuvhara kana kubhuroka kubuda kwemuunganidzi, asi iyo yakakwirira level transmitter mu discharge dhizaini isati yaburitsa iyo inokonzeresa madhigirii echokwadi anogona kubatsira. guruva rinowedzera mukati mebaghouse.
Ichi chinyorwa hachigoni kuvhara mitemo yose yezvigunwe zvekugadzirwa kwakavimbika nekugadzirisa zvirongwa zvekufambisa mumiti ye rPET, asi tarisiro iwe unonzwisisa kuti kune dzakawanda pfungwa dzekufunga uye kuti hapana chinotsiva ruzivo.Funga uchitevera mazano evashambadziri vemichina vakabata rPET flakes munguva yakapfuura.Ava vatengesi vakapfuura nekuedza kwose uye kukanganisa, saka iwe haufaniriwo kuenda kuburikidza navo.
Pamusoro peMunyori: Joseph Lutz ndiye Mutungamiriri weKutengesa uye Kushambadzira kwePelletron Corp.Ane makore gumi nemashanu ehunyanzvi hwekugadzira mapurasitiki akawanda ekugadzirisa zvinhu.Basa rake paPelletron rakatanga muR&D, kwaakadzidza ins uye kubuda kwepneumatics mukuyedza lab.Lutz akatumira akawanda pneumatic conveying masisitimu akapihwa pasi rese uye matatu matsva akapihwa matende.
Tekinoroji nyowani, iyo ichatanga kuNPE mwedzi unouya, inoyambira kana kuchengetedza kwekudzivirira kuchidikanwa pamberi pekutadza kwemidziyo kukanganisa kugadzirwa.
Kuenzaniswa nemutengo wekutenga pre-ruvara resin kana kuisa yakakwirira-inogoneka yepakati musanganiswa kune pre-mix resin uye masterbatch, coloring pamushini inogona kupa zvakakosha mutengo wakanakira, kusanganisira kuderedzwa kwemitengo yezvinhu uye kuwedzera kuchinjika kwemaitiro.
Kune vacuum conveying masisitimu ekugadzira mapurasitiki, yakagadziriswa poda yekubata mhinduro haidiwi nguva dzose.Prefabricated turnkey mhinduro inogona kuva sarudzo yakakwana yehupfu uye yakawanda yakaomeswa mune dzakasiyana siyana maindasitiri.
