Mafekitori ekudzokorodza maPET ane michina yakawanda inokosha yakabatana nemasisitimu ekufambisa emhepo uye emakanika. Nguva yekusashanda nekuda kwekugadzirwa kusina kunaka kwesystem yekutumira, kushandiswa zvisirizvo kwezvikamu, kana kusagadziriswa hazvifanirwe kunge kuri kwechokwadi. Bvunza zvimwe.#Maitiro Akanakisisa
Munhu wese anobvumirana kuti kugadzira zvigadzirwa kubva kuPET (rPET) yakadzokororwa chinhu chakanaka, asi kugadzira zvikamu zvemhando yepamusoro kubva pazvinhu zvisina kurongeka, zvakaita semabhodhoro ePET anotengeswa mushure mekushandiswa, hazvisi nyore. Midziyo yakaoma yekushandisa (semuenzaniso kurongedza kwemaziso, kusefa, kuburitsa, nezvimwewo) inoshandiswa mumafekitori eRPET kuita izvi yakagamuchirwa zvakanyanya - uye zvakakodzera kudaro. Zvinosuwisa kuti masisitimu ekufambisa anofambisa zvinhu pakati pemidziyo iyi dzimwe nguva anowedzerwa senzira yekuzotevera, izvo zvinogona kukonzera kusashanda zvakanaka kwefekitori.
Mubasa rekugadzirisa PET, ndiyo sisitimu yekufambisa inobatanidza matanho ese ekuita pamwe chete - saka inofanira kugadzirwa zvakanangana nechinhu ichi.
Kuchengetedza chirimwa chako chichishanda kunotanga nekugadzirwa kwechirimwa chemhando yepamusoro, uye hazvisi zvese zvekushandisa zvinotakurwa zvakagadzirwa zvakaenzana.ma conveyor e screwMakambani akashanda zvakanaka pamitsara yemachipisi mumakore gumi apfuura anogona kunge asina kukura uye achikurumidza kutadza kushanda pamitsara yemachipisi. Muchina wekufambisa mweya unogona kufambisa machipisi e10,000 lb/hr unogona kungokwanisa kufambisa machipisi e4000 lb/hr. Dambudziko rinowanzoitika nderekusatevedzera nhungamiro dzekugadzira kunyanya pakubata zvinhu zvakadzokororwa.
Chinofambisa mweya chinogona kutakura machipisi anorema 10,000 lb/hr chinogona kungotakura machipisi anorema 4000 lb/hr chete.
Pfungwa huru yekufunga nezvayo ndeyekuti huwandu hushoma hwema PET bottle flakes hunoderedza kugona chaiko kwe transfer system zvichienzaniswa nehuwandu hwakawanda hwe granular materials. Ma flakes acho haana kurongeka zvakanyanya. Izvi zvinoreva kuti michina yekugadzirisa ma sheets inowanzo kuve yakakura. Screw conveyor yema PET chips inogona kunge iri hafu yedhayamita uye inoshandisa zvikamu zviviri kubva muzvitatu simba remota ye screw conveyor yakagadzirirwa ma flakes. Sisitimu ye pneumatic transfer inogona kufambisa 6000 lb/hr chip kuburikidza ne 3 inches. Pombi inofanirwa kunge iri 3 1/2 inches. segment. Solids to gas ratios inosvika 15:1 inogona kushandiswa kuma flake systems, asi zvakanakisa kushandisa flake systems dzine chiyero chepamusoro che 5:1.
Unogona here kushandisa kumhanya kumwe chete kwekufambisa mhepo kuti maflakes abate zvidimbu zvakafanana? Kwete, zvakaderera zvakanyanya kuti zvisafambiswe zvisina kurongeka. Mubhokisi rekuchengetera, koni ye60° inobvumira zvidimbu kuti zviyerere zviri nyore inofanira kunge iri koni refu ye70° yezvidimbu. Zvichienderana nehukuru hwemudziyo wekuchengetera, zvingave zvakakosha kuti silo iite kuti maflakes aenderere. Mizhinji ye "mitemo" iyi inogadzirwa kuburikidza nekuyedza nekukanganisa, saka vimba nemainjiniya vane ruzivo rwekugadzira maitiro chaiwo e rPET flakes.
Mamwe ma glidants echinyakare ekugadzira zvinhu zvakasimba haakwani pamapiritsi emabhodhoro. Nzvimbo inoburitswa silo inoratidzwa pano inobatsirwa nesikuruu yakakombama inopwanya mabhiriji uye inoburitsa maflakes mu airlock inotenderera kuti ipinde musystem yekufambisa mweya ine simba uye yakasimba.
Kugadzirwa zvakanaka kwesystem yekufambisa hakuvimbisi kuvimbika kwesystem. Kuti uwane kushanda kwakavimbika, zvikamu zviri musystem yekufambisa zvinofanirwa kunge zvakagadzirirwa zvakananga rPET flakes.
Mavharuvhu anotenderera anoisa maflakes musystem yekuendesa pressure kana chero chimwe chikamu chemaitiro acho anofanira kunge akasimba kuti agone kutsungirira kushandiswa zvisina kunaka kwemakore kubva kumaflakes asina kurongeka nezvimwe zvese zvinosvibisa zvinopfuura nepaari. Dzimba dzesimbi dzisina ngura dzinorema uye marotor anodhura kupfuura magadzirirwo esimbi dzakatetepa, asi mutengo wekuwedzera unoderedzwa nekudzikira kwenguva yekushanda uye kudzikira kwemari yekutsiva hardware.
Mafurakisi ePET akagadziriswazve akasiyana neePET muchimiro chezvimedu kana kuti huwandu hwezvinhu. Anogumburawo.
Marotor ari mumavharuvhu anotenderera akagadzirirwa lamella anofanira kunge aine rotor yakaita seV uye "gejo" mukati mekupinda kuti aderedze kupwanya nekuvharika. Dzimwe nguva matipi anochinjika anoshandiswa kugadzirisa matambudziko ekupwanya, asi izvi zvinoda kugara zvichigadziriswa uye zvakare kuisa zvidimbu zvidiki zvesimbi mukuita izvi zvinogona kukonzera matambudziko pasi.
Nekuda kwehunhu hwekukwesha kwemaflakes, magokora ari mumasystem ekufambisa nemhepo idambudziko rakajairika. Sisitimu yekufambisa machira ine kumhanya kwakanyanya, uye jira rinotsvedza pamusoro pekunze kwegokora richapfuura nepachubhu yesimbi isina tsvina yegiredhi 10. Vatengesi vakasiyana-siyana vanopa magokora akasarudzika anoderedza dambudziko iri, uye anogona kutogadzirwa nemakambani emakanika.
Kupera kwesimba kunoitika pamipendero yakareba yenguva dzose sezvo zvinhu zvakasimba zvinotsvedza zvichitevedza chikamu chekunze nekumhanya kwakanyanya. Funga nezvekushandisa mipendero mishoma sezvinobvira, uye pamwe mipendero yakakosha yakagadzirirwa kuderedza kupera uku.
Kugadzira nekushandisa hurongwa hwekugadzirisa sisitimu yekufambisa zvinhu yefekitori ndiyo danho rekupedzisira, sezvo paine zvikamu zvakawanda zvinofamba zvinosangana zvakananga nemaburi asina kurongeka uye kusvibiswa. Zvinosuwisa kuti kugadzirisa kwakarongwa kunowanzo furatirwa.
Mamwe marobhoti emhepo anotenderera ane ma shaft seals anoda kugara achisimbiswa kudzivirira kubuda kwemvura. Tsvaga mavharuvhu ane labyrinth shaft seals nema outboard bearings asingade kugadziriswa nguva dzose. Kana mavharuvhu aya achishandiswa mumapepa, zvinowanzodiwa kuchenesa shaft seal nemhepo yakachena yemidziyo. Iva nechokwadi chekuti shaft seal purge pressure yakaiswa nemazvo (kazhinji inenge 5 psig pamusoro pe pressure yepamusoro yekuendesa) uye kuti mhepo iri kuyerera zvechokwadi.
Marotor evharuvhu akasakara anogona kukonzera kubuda kwemvura kwakanyanya muhurongwa hwekuendesa mweya. Kubuda kwemhepo uku kunoderedza huwandu hwemhepo inofambiswa muduct, nokudaro zvichideredza kugona kwehurongwa hwese. Zvinogonawo kukonzera matambudziko ekubatanidza hopper pamusoro pe rotary airlock, saka tarisa mukaha uri pakati pe rotor tip ne housing nguva dzose.
Nekuda kweguruva rakawanda, mafirita emhepo anogona kukurumidza kuvhara zvirimwa zve rPET usati waburitsa mweya unodzosera mumhepo. Iva nechokwadi chekuti differential pressure gauge iri kushanda nemazvo uye iva nechokwadi chekuti mushandi ariongorora nguva nenguva. Guruva rePET rakareruka uye rakapfava rinogona kuvhara kana kuvhara nzira yekubuda nayo yemuunganidzi, asi chinotumira chepamusoro mu discharge cone chinogona kubatsira kuona kuvharika uku kusati kwakonzera matambudziko makuru. Iva nechokwadi chekuti unobvisa guruva mukati mebhegi nguva nenguva.
Chinyorwa chino hachigone kufukidza mitemo yese yekugadzirwa kwakavimbika uye kugadziriswa kwemasisitimu ekutamisa muzvifekitori zverPET, asi ndinovimba unonzwisisa kuti pane zvakawanda zvekufunga nezvazvo uye kuti hapana chinotsiva ruzivo. Funga nezvekutevera mazano evatengesi vemidziyo vakambobata maflakes erPET kare. Vatengesi ava vakapfuura nemumiedzo yese nekukanganisa, saka haufanirwe kuapfuurawo.
Nezve Munyori: Joseph Lutz ndiye Mutungamiriri weKutengesa neKushambadzira wePelletron Corp. Ane ruzivo rwemakore gumi nemashanu mukugadzira mhinduro dzekubata zvinhu zvepurasitiki. Basa rake kuPelletron rakatanga muR&D, kwaakadzidza zvese nezvepneumatics murabhoritari yekuyedza. Lutz akaraira masisitimu akawanda ekufambisa mweya pasi rese uye akapihwa mapatenti matatu matsva ezvigadzirwa.
Tekinoroji itsva, iyo ichatanga kuburitswa paNPE mwedzi unouya, inonyevera kana paine chikonzero chekugadzirisa michina isati yakundikana.
Zvichienzaniswa nemutengo wekutenga resin yakapendwa kare kana kuisa muchina wekusanganisa wepakati une simba guru we pre-mix resin ne masterbatch, kupenda pamuchina kunogona kupa mabhenefiti makuru emutengo, kusanganisira kuderedzwa kwemitengo yezvinhu uye kuwedzera kuchinjika kwemaitiro.
Kune masisitimu ekutakura vacuum ekugadzirisa mapurasitiki, mhinduro dzekugadzirisa hupfu dzakagadzirwa nemaoko hadzidiwi nguva dzose. Mhinduro dzekugadzirisa dzakagadzirwa kare dzinogona kuva sarudzo yakakwana yehupfu nezvinhu zvakasimba zvakawanda mumaindasitiri akasiyana-siyana.
