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 zvemhando yepamusoro kubva kune zvakasvibiswa zvakasvibiswa, zvakadai semabhodhoro ePET-post-consumer, hazvisi nyore.Iyo yakaoma maitiro ekugadzirisa (eg optical sorting, filtration). , extrusion, etc.) inoshandiswa mumiti ye rPET kuti iite izvi yakagamuchira kutariswa kwakawanda - uye zvakakodzera zvakadaro.Zvinosuruvarisa, mafambisirwo ekufambisa anofambisa zvinhu pakati pezvigadzirwa izvi dzimwe nguva anowedzerwa sechinhu chinotevera, izvo zvinogona kuguma zvishoma kudarika zvakakwana zvakakwana. chirimwa kuita.
Mukuita kwePET kudzokorodza kushanda, ndiyo nzira yekufambisa inosunga matanho ese pamwe chete - 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 yechip mumakore gumi adarika inogona kunge yakaderera uye inokundikana nekukurumidza pamitsetse yeflake.A pneumatic conveyor inokwanisa kufambisa 10,000 lb/hr machipisi ingangokwanisa kufambisa 4000 lb/hr chips.A common pitfall haisi kutevedzera dhizaini yakanangana nekubata zvinhu zvakadzokororwa.
Pneumatic conveyor inokwanisa kufambisa 10,000 lb/hr machipisi inogona chete kufambisa 4000 lb/hr machipisi.
Iyo inonyanya kukosha pfungwa yekufunga ndeyekuti iyo yakaderera yakawanda density yePET bhodhoro flakes inoderedza chaiyo chaiyo yekutamisa sisitimu kana ichienzaniswa neakakwira yakawanda density yegranular materials.Maflakes zvakare akawandisa muchimiro.Izvi zvinoreva kuti midziyo yekugadzirisa mapepa acho anowanzo hombe.A screw conveyor yePET chips inogona kunge iri hafu yedhayamita uye inoshandisa zvikamu zviviri muzvitatu simba remota yescrew conveyor yakagadzirirwa flakes.A pneumatic transfer system inogona kufambisa 6000 lb/hr chip kuburikidza nemainches matatu. .Pipe inoda kuva 31/2 inches.segment.Solids kune gasi reshiyo inosvika 15:1 inogona kushandiswa machipisi, asi zviri nani kushandisa maflake masisitimu ane huwandu hwakawanda hwe5:1.
Unokwanisa here kushandisa sipidhi yepickup yemhepo yakafanana kuitira maflakes kubata zvidimbu zvakaumbwa zvakafanana?Kwete, yakadzikira zvakanyanya kuti ukwanise kufamba zvisina kujairika. Mubhokisi rekuchengetera, 60° koni inobvumira zvidimbu kuyerera zviri nyore inofanira kunge yakareba 70° cone for flakes.Zvichienderana nehukuru hwemudziyo wekuchengetera, zvingave zvakakosha kumisa silo kuti maflakes atenderere.Mizhinji yeiyi "mitemo" inogadzirwa kuburikidza nekuedza uye kukanganisa, saka vimba nevanjiniya vane ruzivo rwekugadzira maitiro chaiwo. ye rPET 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 muchirongwa chekumanikidza kana chero chimwe chikamu chegadziriro chinofanira kunge chiri chakaremera-basa kutsungirira makore ekushungurudzwa kubva kune zvisina kujairika maflakes uye zvimwe zvese zvinosvibisa zvinopfuura nemazviri.Heavy-duty cast stainless steel housing uye rotor zvechokwadi inodhura. kupfuura yakatetepa sheet simbi dhizaini, asi iyo yekuwedzera mutengo inodzikiswa nekudzikiswa nguva uye kuderedzwa kwehardware kutsiva mutengo.
Akadzokororwazve PET maflakes anosiyana kubva kuPET flakes mune particle shape kana bulk density.Iyo zvakare abrasive.
Rotor in rotary valves yakagadzirirwa lamella inofanira kuva neV-shaped rotor uye "gejo" mune inopinza kuderedza kuputika uye kuvhara. Mazano anoshanduka dzimwe nguva anoshandiswa kukunda nyaya dzekucheka, asi izvi zvinoda kugara zvichigadziriswa uye kuunzawo zvimedu zviduku zvesimbi mukati. nzira inogona kukonzera matambudziko pasi pemvura.
Nekuda kwekukaruka kwemaflakes, magokora ari mupneumatic conveying system idambudziko rinowanzoitika.Iyo pepa rekutakura hurongwa rine spidhi yakakwira, uye jira rinotsvedza richitevedza kunze kwegokora richapfuura nepakati pegiredhi 10 stainless steel chubhu.Various vatengesi vanopa magokora ane hunyanzvi anoderedza dambudziko iri, uye anogona kugadzirwa nemakanika makondirakiti.
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 seals inoda kugara yakasungwa kuti isabuda.Tsvaga mavharuvhu ane labyrinth shaft seals uye outboard mabearings asingadi kugadziriswa nguva dzose.Kana mavharuvhu aya achishandiswa mukushandiswa kwemashizha, zvinowanzodiwa kuchenesa shaft. chisimbiso nemhepo yakachena yemudziyo.Iva nechokwadi chokuti shaft seal purge pressure inogadziriswa zvakanaka (kazhinji inenge 5 psig pamusoro pepamusoro pekumanikidzwa kwekutumira) uye kuti mhepo iri kunyatsoyerera.
Yakasakara inotenderera mavharuvhu rotors inogona kukonzera yakawandisa kuvuza mune yakanaka yekumanikidza kuburitsa masisitimu.Kudonha uku kunoderedza huwandu hwemhepo inofambiswa mugero, nekudaro ichidzikisa huwandu hwese hwehurongwa.Inogona zvakare kukonzera nyaya dzemabhiriji nehopper pamusoro peinotenderera airlock, saka tarisa kusiyana pakati pe rotor tip uye imba nguva dzose.
Nekuda kwekuremerwa kweguruva, mafirita emhepo anogona kukurumidza kuvhara rPET zvidyarwa asati aburitsa mhepo inodzosera kumashure mumhepo.Iva nechokwadi chekusiyanisa kudzvinyirira gauge iri kushanda nemazvo uye iva nechokwadi chekuti anoshanda anoiongorora nguva dzose.Chakanyanya kujeka uye fluffy PET guruva rinogona kuvhara kana bhiriji pekubuda kwemuunganidzi, asi dhigirii yepamusoro mukoni yekuburitsa inogona kubatsira kuona zvivharo izvi zvisati zvakonzera matambudziko makuru.Iva nechokwadi chekuti unogara uchibvisa guruva mukati mebaghouse.
Ichi chinyorwa hachigone kuvhara mitemo yese yezvigunwe zvekugadzirwa kwakavimbika uye kuchengetedza kwekutamisa masisitimu mu rPET zvirimwa, asi tarisiro iwe unonzwisisa kuti pane akawanda mapoinzi ekufunga uye kuti hapana chinotsiva ruzivo.Funga uchitevera kurudziro yevatengesi vemidziyo avo vakabata rPET flakes munguva yakapfuura.Ava vatengesi vakapfuura nemuyedzo yose uye kukanganisa, saka haufaniri kupfuura navo zvakare.
NezveMunyori: 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 mune yekuyedza lab.Lutz akatumira masisitimu akawanda ekufambisa mweya pasi rese uye akapihwa matatu matsva ezvigadzirwa.
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 musanganisi kune pre-mix resin uye masterbatch, coloring pamushini inogona kupa zvakakosha mutengo wakanakira, kusanganisira kuderedzwa kwemitengo yezvinhu uye kuwedzera kushanduka 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.
