I-380 double disc refiner iyithuluzi lokudonsa eliwumgogodla elakhelwe imigqa yokukhiqiza ephakathi nendawo nenkulu embonini yokwenza iphepha. Igama layo lisuselwa kububanzi obujwayelekile bamadiski okucwengisiswa (380mm). Ukusebenzisa inzuzo yesakhiwo "yokucwenga okuphindwe kabili kwe-counter-rotating", ifinyelela ukuhlanganiswa okuphumelelayo kokusika kwe-fiber kanye ne-fibrillation. Njengoba ikwazi ukuzivumelanisa nezimo ezihlukahlukene zezinto zokusetshenziswa ezifana ne-wood pulp, i-waste paper pulp, ne-straw pulp, ingahlangabezana nezidingo zokucwenga zamamaki ephepha ahlukene kuhlanganise nephepha lamasiko, iphepha lokupakisha, nephepha lethishu, okuyenza ibe into esetshenziswayo ethandwayo yokulinganisa ukusebenza kahle kokukhiqiza, ikhwalithi yephepha, kanye nezindleko zokusebenzisa amandla.

I. Ukucaciswa Okubalulekile kanye Nemingcele

1. Amapharamitha Esakhiwo Esiyisisekelo

• Ububanzi bokuzisholo bamadiski okucwengisiswa: 380mm (isihlonzi sokucaciswa okuyisisekelo, sinquma ukucwengwa kwendawo yokuxhumana namandla okukhiqiza)
• Inombolo yama-disc wokucwenga: izingcezu ze-2 (inhlanganisela ye-disc ehambayo + i-disc engaguquki, i-counter-rotation design ithuthukisa ukufana kokucubungula i-fiber)
• Iphrofayili yezinyo le-Disc: I-serrated eyenziwe ngokwezifiso, i-trapezoidal, i-spiral (evumelana nezinjongo ezihlukene zokucwenga, uhlobo lwe-shear ozikhethela / uhlobo lwe-fibrillation)
• Ibanga lokulungiswa kwegebe lediski: 0.1-1.0mm (ukulungiswa kokunemba kukagesi, ukusekela ukuzivumelanisa okuguquguqukayo nezici ze-pulp)
• Ubukhulu bezinto zonke (L×W×H): Cishe 1800×1200×1500mm (umklamo ohlangene, wonga indawo yokufaka)
• Isisindo sesisetshenziswa: Cishe 1200-1500kg (ukuzivumelanisa nezimfuneko eziyisisekelo zokuthwala umthwalo wemigqa yokukhiqiza)

2. Amapharamitha wokuSebenza kokuSebenza

• Ukugxila kokucwenga okuguquguqukayo: Ukungaguquguquki okuphansi (3% -8%), ukungaguquguquki okumaphakathi (8% -15%) (ukujwayela kokugxilisa okukabili, izinqubo zokukhiqiza ezivumelana nezimo)
• Amandla okukhiqiza: 15-30t/d (imishini eyodwa, iguquguquka ngokuguquguqukayo ngokuya ngohlobo lwe-pulp kanye nokuqina kokucwenga)
• Amandla emoto: 110-160kW (injini kazwelonke esebenza kahle kakhulu, amandla aguqulelwe kuzidingo zamandla okukhiqiza, isilinganiso esilungiselelwe ukusetshenziswa kwamandla)
• Isivinini esilinganiselwe: 1500-3000r/min (ukulawula isivinini sokuguqulwa kwemvamisa kuyatholakala, ukuzivumelanisa nezimfuneko zokuqina kokucwenga okuhlukile)
• Isivinini se-Disc linear: 23.8-47.7m/s (isivinini esiwumugqa sihlanganiswe nephrofayili yezinyo ukuze kuzuzwe ukulawula okunembile kwamandla okugunda)
• Ukucindezela kokuphakelayo: 0.2-0.4MPa (ukuphakela okuzinzile, ukuqinisekisa ukuqhubeka kokucwengwa)
• Izinga lokushisa elisebenzayo: ≤80 ℃ (ukuzivumelanisa nezinga lokushisa elivamile lokucubungula i-pulp, ukumelana nokushisa kwemishini kuhlangabezana nezindinganiso)

3. Amapharamitha we-Material and Configuration

• Okubalulekile kwediski: Ingxubevange ye-chromium ephezulu, insimbi engagqwali (uma uthanda) (ingagugi futhi imelana nokugqwala, inweba impilo yesevisi, ijwayelana nezinto ezingavuthiwe eziqukethe ukungcola okufana ne-waste paper pulp)
• I-main shaft material: 45# insimbi eyakhiwe (icishiwe futhi ithambile, amandla aphezulu nokusebenza okuzinzile)
• Indlela yokubeka uphawu: I-Mechanical seal ehlanganisiwe + uphawu lukawoyela wamathambo (ukuvalwa okuphindwe kabili, ukuvimbela ukuvuza kwe-pulp nokuguga)
• Uhlelo lokulawula: Ukulawula okuzenzakalelayo kwe-PLC (okusekela ukuqapha kwesikhathi sangempela nokulungiswa okuzenzakalelayo kwegebe le-disc, isivinini, namandla okukhiqiza, ahambisana nohlelo lokulawula oluphakathi lomugqa wokukhiqiza)
• Ukuvikela ukuphepha: Ukuvikelwa kokulayishwa ngokweqile, ukuvikelwa kwezinga lokushisa elingaphezulu, ukuvikela ukushoda kwezinto (ukuvikela okuningi ukuze kuqinisekiswe ukuphepha kwezisetshenziswa kanye nabaqhubi)

II. Izinzuzo Eziyinhloko Zezobuchwepheshe

1. Ukucwenga Okuphumelelayo Ngokuguquguquka Kwekhono Elinamandla: Umklamo ojikelezayo we-double-disc counter-rotating uqinisekisa ukuthintana okugcwele phakathi kwe-pulp nama-discs, ngomthamo wokucubungula we-15-30t / d ngesikhathi seyunithi ngayinye, ukuhlangabezana nezidingo zamandla wemishini eyodwa noma eminingi efanayo emigqeni yokukhiqiza ephakathi nendawo enkulu. Ukusebenza kahle kokucwenga kungaphezulu kwama-30% ngaphezu kwalokho kwabacwengi bediski elilodwa bencazelo efanayo.
2. Ukuguqulwa Okuqondile Kwe-Fiber: Ngokulungiswa kwegebe ngokunemba (ukunemba kwezinga le-0.1mm) kanye namaphrofayili wamazinyo enziwe ngokwezifiso, ngeke nje kufinyelele ukusika okulinganiselwe kwemicu emifushane kodwa futhi kuqinisekise ukufiphala kwemicu emide, okwenza ukusatshalaliswa kobude befayibha kunengqondo futhi kuthuthukise amandla ephepha nokufana kanyekanye.
3. Ukusetshenziswa Kwamandla Okulinganiselayo Nokuzinza: Ifakwe amamotho asebenza kahle angu-110-160kW kanye nobuchwepheshe bokulawula isivinini sokuguqulwa kwemvamisa, ukusetshenziswa kwamandla okucwengisiswayo kuphansi njenge-pulp engu-80-120kWh/t, yonga u-15% -20% wamandla uma kuqhathaniswa nemishini yendabuko; ukubekwa uphawu okuphindwe kabili kanye nokwakhiwa kweshafu yensimbi efojiwe kunciphisa izinga lokuhluleka kwemishini, isikhathi sokusebenza esiqhubekayo sifinyelela ngaphezu kuka-8000h/ngonyaka.
4. Ukuguquguquka Okubanzi Nokusebenza Okulula: Ihambisana nezinqubo zokucwenga ezingaguquguquki eziphansi naphakathi, ingakwazi ukucubungula izinto zokusetshenziswa ezihlukahlukene ezifana ne-pulp yezinkuni, i-waste paper pulp, ne-straw pulp, ivumelane namamaki ephepha ahlukene kuhlanganise nephepha lamasiko nephepha lokupakisha; uhlelo lokulawula okuzenzakalelayo lwe-PLC lwenza kube lula ukusebenza, lusekela ukuqapha okukude nokulungiswa kwepharamitha, futhi kunciphisa izindleko zabasebenzi.

III. Izimo zohlelo lokusebenza kanye neziphakamiso

• Imigqa yokukhiqiza esebenzayo: Imigqa yokukhiqiza iphepha eliphakathi nendawo elikhulu elinokukhishwa kwansuku zonke kwe-100-500t, engasetshenziswa njengemishini yokucwenga eyinhloko noma imishini yokuqedela yokucwenga.
• Amamaki ephepha akhethwayo: Iphepha lesiko (iphepha lokubhala, iphepha lokuphrinta), iphepha lokupakisha (i-linerboard, i-corrugating medium), i-tissue paper, njll., ifaneleka ngokukhethekile imikhiqizo enezidingo eziphezulu ze-fiber bonding force kanye nokufana kwephepha.
• Iziphakamiso zokufaka isicelo: Lapho ucubungula i-pulp yephepha elilahlwayo, kufanele kunikezwe kuqala ama-disc aqinile we-chromium alloy discs ukumelana nokunciphisa ukuguga kwemishini okubangelwa ukungcola; lapho ukhiqiza iphepha lokupakisha elinamandla amakhulu, inqubo yokucwenga ehambisanayo ephakathi (i-8% -12% yokuhlushwa) ingamukelwa ukuze kuthuthukiswe i-fiber fibrillation degree; xhuma nesistimu yokulawula emaphakathi yomugqa wokukhiqiza ukuze uthole ukuthuthukiswa okuxhumene kwamapharamitha wokucwenga kanye nezinqubo zokwenza iphepha.
