I-screw extruder eyodwa: ifanele into eyodwa kanye nokudla okujwayelekile kwemfuyo kanye nezinkukhu.
I-Twin screw extruder: ngokuvamile isetshenziswa ekukhiqizweni kokuphakelayo kwezilwane zasemanzini okune-value okusezingeni eliphezulu, okufana ne-eel, turtle, kanye ne-juvenile fish feed, ngoba amanani ale mikhiqizo ethengiswa emakethe anele ukukhokha izindleko zokukhiqiza imikhiqizo kusetshenziswa. ubuchwepheshe be-screw amabili; Ukwengeza, okunye okuphakelayo okukhethekile kwasemanzini, okufana nezinhlayiya eziphakelayo zasemanzini (ezinobubanzi obungu-0.8~1.5mm), ukudla okunamafutha aphezulu, nokudla okunomthamo omncane wokukhiqiza kodwa ifomula eshintsha njalo, nakho kudingeka kukhiqizwe kusetshenziswa isikulufu esiphindwe kabili. .
Kufanele kucaciswe ukuthi umehluko ongenhla awuqinisekile. Isibonelo, siphakamisa ukuthi kusetshenziswe izikulufu ezingamawele ukuze kukhiqizwe okuphakelayo kwasemanzini, kodwa manje izinkampani eziningi zisebenzisa izikulufu ezizodwa ukuze zikhiqize ukudla kwasemanzini. Kunomehluko ekusetshenzisweni kokubili kokuphakela kwamanzi. Ngamafuphi, uma kuqhathaniswa nesikulufa esisodwa, isikulufu esiphindwe kabili sinezinzuzo ezilandelayo:
① Ukuvumelana nezimo kwezinto zokusetshenziswa kubanzi, ezingavumelana nokucutshungulwa kwe-viscosity ephezulu, i-viscosity ephansi, okuqukethwe kukawoyela okuphezulu, umswakama ophezulu noma i-viscosity, okunamafutha, okokusetshenziswa okuluhlaza okumanzi kakhulu, nezinye izinto ezingase zishelele kusikulufa esisodwa (SSE) .
② Kunemikhawulo embalwa kusayizi wezinhlayiyana zezinto zokusetshenziswa, ezingajwayela ukucutshungulwa kwezinto zokusetshenziswa ukusuka kumpushana encane ukuya ezinhlayiyeni zempushana emahhadla kanye nokucutshungulwa kwesikulufu esisodwa kwezinto ezinosayizi bezinhlayiyana ngaphandle kwebanga elithile.
③ Ukugeleza kwempahla ngaphakathi komgqomo kufana kakhulu, futhi isitimu, amanzi, njll. kungangezwa ukufeza umphumela oyifunayo womkhiqizo.
④ Ikhwalithi yangaphakathi nengaphandle yomkhiqizo ingcono, engafinyelela isimo esihle kakhulu sokufana futhi enze ukwakheka kwamangqamuzana okubalulekile kuhlelwe ngokulinganayo. Ingaphezulu libushelelezi ngesikhathi senqubo ye-extrusion. Izinhlayiya zomkhiqizo zinokufana okuphezulu nokufana okuhle.
⑤ Umphumela wokuvuthwa kanye ne-homogenization ungcono, ngokuvamile unedigri yokuvuthwa isitashi engaphezu kuka-95%, okwenza ukudla okusetshenzwe emanzini kugcine ukuqina emanzini, kuvimbele ukulahlekelwa imisoco yomkhiqizo, futhi kube lula ukugayeka nokumunca.
⑥ Isivuno esiphezulu ngaphansi kwamandla alinganayo. Ukusebenza okuhle kokuxuba kunika amandla i-homogenization ngesikhathi sokushisa okutholwe yizinto ezibonakalayo, kusheshisa izinga lokuvuthwa kwento, kunciphisa ukuguquguquka kwezinga lokushisa lezinto ezibonakalayo, futhi kuthuthukisa ukuphuma kwemikhiqizo ekhishwe.
⑦ Ukwehlukahlukana komkhiqizo nokuvumelana nezimo kubanzi, futhi ingakwazi ukucubungula ukudla kwasemanzini okuncane, ifomula kawoyela ephezulu, umswakama ophezulu, imikhiqizo enamathelayo ephezulu, nemibala eminingi, uhlobo lwesemishi, kanye nemikhiqizo emise okwesipesheli.
⑧ Ukusebenza kwenqubo kulula kakhulu, futhi isivinini sokuphotha singashintshwa ngokuya ngezidingo zomkhiqizo ocutshunguliwe. Ngenxa yesici sokuzihlanza, ukuhlanza kulula kakhulu, futhi asikho isidingo sokuhlukanisa imishini ngemva kokucubungula ngakunye.
⑨ Izingxenye ezisengozini zigqoka kancane. Umbono oyiphutha ovamile ukuthi isikulufa esisodwa sinokuguga okuncane. Eqinisweni, phakathi nenqubo ye-twin screw extrusion, ngenxa yezinto ezizinzile zokuthutha nezici zokugeleza kwempahla, ukuguga kwento ekusikulufi nomkhono wangaphakathi wombhobho kuncane kunokwesikulufu esisodwa. Nakuba inani lezikulufu liyisethi eyodwa ngaphezulu, izindleko zezesekeli zisaphansi kunalezo zesikulufa esisodwa.
⑩ Izindleko zokukhiqiza ziphansi. Ngenxa yokuzinza okuhle kokusebenza kwemodeli yesikulufu esingamawele, kunezindleko zokuqalisa ezimbalwa, ukumosheka kwamanzi negesi okuncane, izindleko zokusebenza eziphansi, ukusebenza kahle kokudlulisa ukushisa, isivuno esikhulu, kanye nezinkomba zokukhishwa kukagesi okuphezulu kunqubo yokucubungula okuphakelayo. Ngaphezu kwalokho, izindleko zezesekeli nazo ziphansi, futhi izindleko zokukhiqiza zokugcina zisaphansi kakhulu uma kuqhathaniswa nesikulufa esisodwa.
Kungenxa ngqo yezinzuzo eziningi zesikulufu esingamawele uma kuqhathaniswa nesikulufu esisodwa ekukhiqizeni okuphakelayo kwasemanzini lapho sikhuthaza ukuthi ukukhethwa kwe-twin screw extruder uma izimo zivuma kuzo zonke izici.
Okulandelayo yizinyathelo zokuphepha okufanele zithathwe uma usebenzisa i-twin screw extruder:
1. Ukuphepha komsebenzi:
-Ngaphambi kokusebenzisa i-twin screw extruder, kuyadingeka ukujwayelana nezinqubo zokusebenza zemishini, izinyathelo zokuphepha, kanye nokusetshenziswa kwemishini yokuvala shaqa izimo eziphuthumayo.
-Abasebenzi kufanele bagqoke izinto zokuzivikela ezihambisanayo ukuze bagweme izingozi kanye nokulimala okungenzeka ngesikhathi sokusebenza.
-Ukuqinisekisa ukuphepha kwendawo yokusebenza ezungeze okokusebenza futhi uvimbele izingozi njengokushelela nokushayisana.
2. Ukugcinwa kwezisetshenziswa:
-Gcina futhi unakekele i-twin screw extruder, okuhlanganisa ukuhlanza, ukuthambisa, ukuqinisa amabhawodi, njll. Qinisekisa ukuthi okokusebenza kusesimweni esihle sokusebenza.
-Hlala uhlola izingxenye ezigqokwa kalula njengezikulufu, amawasha, nama-assemblies, bese uzishintsha ngesikhathi esifanele ukuze uqinisekise ukusebenza okuvamile kwemishini.
-Yenza izinhlelo zokulungisa ezihambisanayo ezisekelwe ezikhathini eziningi zokusetshenziswa kwemishini nendawo yokusebenza ukuze kuqinisekiswe ukusebenza okuzinzile kwesikhathi eside kwemishini.
3. Ukuzivumelanisa nezimo zezinto ezingavuthiwe:
-Imishini yokukhukhumeza isikulufu esiwele inezidingo eziphezulu zezinto ezingavuthiwe, futhi izinto ezingavuthiwe ezihlukile zingadinga imingcele yenqubo yokukhukhumeza ehlukene nezindlela zokusebenza.
-Lapho ukhetha imishini, kuyadingeka ukuqinisekisa ukuthi imodeli kanye nokucaciswa kwemishini kufanelekile ubuchwepheshe bokucubungula obudingekayo ngokusekelwe ezicini zezinto zokusetshenziswa kanye nezidingo zokucubungula.
4. Izinga lokushisa nokulawula isivinini:
-Izinga lokushisa kanye nesivinini sokuzungeza amapharamitha abalulekile athinta umphumela wokucubungula we-twin screw extruder, futhi adinga ukulungiswa nokulawula okunengqondo.
-Ukulawula izinga lokushisa kufanele kulungiswe ngokuya ngezinto ezingavuthiwe ezahlukahlukene kanye nezidingo zokucubungula. Izinga lokushisa elidlulele lingaholela ekuvuthweni ngokweqile noma ekushisweni kwezinto ezingavuthiwe, kuthinte ikhwalithi yomkhiqizo.
-Ukulawulwa kwesivinini sokujikeleza nakho kudinga ukulungiswa ngokufanele ngokusekelwe ezintweni ezingavuthiwe kanye nezidingo zokucubungula. Isivinini sokujikeleza esiphezulu noma esiphansi singathinta umphumela wokucubungula kanye nekhwalithi yomkhiqizo.
5. Inani lempahla nokulawula inqubo:
-Ukulawulwa komthamo wezinto ezibonakalayo kudinga ukulungiswa ngokuya ngemininingwane yemishini kanye nezici zezinto ezingavuthiwe. Umthamo wezinto ezisetshenziswayo oweqile ungase ubangele ukuvinjelwa kwemishini, kuyilapho ivolumu yezinto ezibonakalayo ephansi kakhulu inganciphisa ukusebenza kahle kokucubungula.
-Ukulawulwa kwenqubo kudinga ukuhlelwa okunengqondo kokulandelana kokuphakelayo nokukhishwa kwezinto ezingavuthiwe, ukuqinisekisa ukusatshalaliswa okufanayo kwezinto ezingavuthiwe kanye nokukhishwa okuvamile kokuphumayo, nokugwema ukuvinjwa nokuxubana kwezimo.
6. Ukuhlanza kanye nenhlanzeko:
-Uma usebenzisa i-twin screw extruder, ukunakwa kufanele kukhokhwe ekuhlanzekeni nasekuphathweni kwenhlanzeko kwemishini, futhi ukuhlanzwa okuvamile kwezinsalela nothuli ngaphakathi kwemishini kufanele kwenziwe ukuvimbela ukungcoliswa okuphambene nokukhula kwebhaktheriya.
