I-380 double disc refiner iyithuluzi eliyinhloko lokugaya elenzelwe imigqa yokukhiqiza ephakathi nendawo nekhulu embonini yokwenza amaphepha. Igama layo livela kububanzi obujwayelekile bamadiski okuhlanza (380mm). Isebenzisa inzuzo yesakhiwo "sokucwenga okujikelezayo okuphindwe kabili", ifinyelela ukuhlanganiswa okuphumelelayo kokusika i-fiber kanye ne-fibrillation. Ivumelana kakhulu nezinto zokusetshenziswa ezahlukahlukene njenge-pulp yokhuni, i-pulp yephepha elilahliwe, kanye ne-pulp yotshani, ingahlangabezana nezidingo zokucwenga zamabanga ahlukene ephepha kufaka phakathi iphepha lamasiko, iphepha lokupakisha, kanye nephepha lezicubu, okwenza kube yimishini ekhethwayo yokulinganisela ukusebenza kahle kokukhiqiza, ikhwalithi yephepha, kanye nezindleko zokusetshenziswa kwamandla.

I. Imininingwane Eyinhloko kanye namapharamitha

1. Amapharamitha Esakhiwo Esiyisisekelo

• Ububanzi obujwayelekile bamadiski okuhlanza: 380mm (isihlonzi sencazelo eyinhloko, esinquma indawo yokuxhumana yokuhlanza kanye nomthamo wokukhiqiza)
• Inani lamadiski okuhlunga: izingcezu ezi-2 (inhlanganisela yamadiski ahambayo + idiski egxilile, ukwakheka okujikelezayo okuphikisanayo kuthuthukisa ukufana kokucubungula ifayibha)
• Iphrofayili yezinyo le-Disc: I-serrated eyenziwe ngokwezifiso, i-trapezoidal, i-spiral (ivumelana nezinjongo ezahlukene zokucwenga, uhlobo lokugunda/uhlobo lwe-fibrillation olukhethwayo)
• Ububanzi bokulungiswa kwesikhala sediski: 0.1-1.0mm (ukulungiswa kokunemba kukagesi, okusekela ukuzivumelanisa okuguquguqukayo nezici ze-pulp)
• Ubukhulu bemishini iyonke (L×W×H): Cishe 1800×1200×1500mm (umklamo omncane, wonga isikhala sokufaka)
• Isisindo semishini: Cishe 1200-1500kg (ukuzivumelanisa nezidingo eziyisisekelo zokuthwala umthwalo wemigqa yokukhiqiza)

2. Amapharamitha Okusebenza Kokusebenza

• Ukuhlushwa okulungisekayo: Ukungaguquguquki okuphansi (3%-8%), ukungaguquguquki okuphakathi (8%-15%) (ukuguquguquka kokuhlushwa okubili, izinqubo zokukhiqiza ezihambisana nezimo)
• Umthamo wokukhiqiza: 15-30t/ngosuku (imishini eyodwa, elungiswa ngokuguquguqukayo ngokuya ngohlobo lwe-pulp kanye nokuqina kokucwenga)
• Amandla enjini: 110-160kW (injini ejwayelekile kazwelonke esebenza kahle kakhulu, amandla afanela izidingo zamandla okukhiqiza, isilinganiso sokusetshenziswa kwamandla esilungiselelwe)
• Isivinini esilinganiselwe: 1500-3000r/min (umthethonqubo wesivinini sokuguqulwa kwemvamisa uyatholakala, ovumelana nezidingo ezahlukene zokuqina kokucwenga)
• Isivinini esiqondile sediski: 23.8-47.7m/s (isivinini esiqondile sihlanganiswe nephrofayili yamazinyo ukuze kufezwe ukulawula okunembile kwamandla okusika)
• Ingcindezi yokudla: 0.2-0.4MPa (ukudla okuzinzile, okuqinisekisa ukuqhubeka kokucwengisisa)
• Izinga lokushisa lokusebenza: ≤80℃ (ukuzivumelanisa nokushisa okuvamile kokucubungula i-pulp, ukumelana nokushisa kwemishini kuhlangabezana nezindinganiso)

3. Amapharamitha Ezinto Nokucushwa

• Izinto zediski: I-alloy ene-chromium ephezulu, insimbi engagqwali (ongakukhetha) (engagugi futhi engagqwali, enweba isikhathi senkonzo, evumelana nezinto zokusetshenziswa eziqukethe ukungcola njenge-pulp yephepha elingcolile)
• Izinto zomgodi oyinhloko: insimbi eyakhiwe engu-45# (ecinyiwe futhi ethambile, enamandla aphezulu kanye nokusebenza okuzinzile)
• Indlela yokuvala: Ukuvalwa okuhlanganisiwe komshini + uphawu lwamafutha oluhlanganisiwe (ukuvalwa okuphindwe kabili, okuvimbela ukuvuza nokuguguleka kwe-pulp)
• Uhlelo lokulawula: Ukulawula okuzenzakalelayo kwe-PLC (kusekela ukuqapha kwesikhathi sangempela kanye nokulungiswa okuzenzakalelayo kwegebe lediski, isivinini, kanye nomthamo wokukhiqiza, okuhambisana nohlelo lokulawula oluphakathi lomugqa wokukhiqiza)
• Ukuvikelwa kokuphepha: Ukuvikelwa komthwalo oweqile, ukuvikelwa kokushisa okweqile, ukuvikelwa kokuntuleka kwezinto (ukuvikelwa okuningi ukuqinisekisa ukuphepha kwemishini kanye nabaqhubi)

II. Izinzuzo Eziyinhloko Zobuchwepheshe

1. Ukucwenga Okusebenzayo Okunokuguquguquka Okuqinile Komthamo: Umklamo ojikelezayo ophindwe kabili uqinisekisa ukuxhumana okugcwele phakathi kwe-pulp nama-disc, ngomthamo wokucubungula ongu-15-30t/d ngeyunithi ngayinye, okuhlangabezana nezidingo zomthamo wemishini eyodwa noma eminingi ehambisanayo emigqeni yokukhiqiza ephakathi nekhulu. Ukusebenza kahle kokucwenga kungaphezu kuka-30% kunokwabacwengi be-single-disc abanezici ezifanayo.
2. Ukuguqulwa Kwefayibha Okunembile: Ngokulungisa igebe elinembile (ukunemba kwezinga elingu-0.1mm) kanye namaphrofayili amazinyo angenziwa ngezifiso, ayikwazi nje ukufeza ukusika okulinganiselwe kwemicu emifushane kodwa futhi iqinisekise ukuqina kwemicu emide, okwenza ukusatshalaliswa kobude befayibha kube okunengqondo futhi kuthuthukise amandla ephepha kanye nokufana ngasikhathi sinye.
3. Ukusetshenziswa Kwamandla Okulinganiselwe Nokuzinza: Ifakwe ama-motor asebenza kahle kakhulu angu-110-160kW kanye nobuchwepheshe bokulawula isivinini sokuguqulwa kwemvamisa, ukusetshenziswa kwamandla okuhlanza iyunithi kuphansi njengo-80-120kWh/t pulp, konga amandla angu-15%-20% uma kuqhathaniswa nemishini yendabuko; ukwakheka komgodi oyinhloko wensimbi oqinisiwe kanye nowokubumba kunciphisa izinga lokuhluleka kwemishini, isikhathi sokusebenza esiqhubekayo sifinyelela ngaphezu kwamahora angu-8000/ngonyaka.
4. Ukuzivumelanisa Nezimo Okubanzi Nokusebenza Okulula: Iyahambisana nezinqubo zokucwenga eziphansi neziphakathi nendawo, ingacubungula izinto zokusetshenziswa ezahlukahlukene njenge-pulp yokhuni, i-pulp yephepha elilahliwe, kanye ne-pulp yotshani, ivumelane namazinga ahlukene ephepha kufaka phakathi iphepha lamasiko kanye nephepha lokupakisha; uhlelo lokulawula oluzenzakalelayo lwe-PLC lwenza kube lula ukusebenza, lusekela ukuqapha okukude kanye nokulungiswa kwamapharamitha, futhi lunciphisa izindleko zabasebenzi.

III. Izimo Neziphakamiso Zokusebenzisa

• Imigqa yokukhiqiza esebenzayo: Imigqa yokukhiqiza iphepha ephakathi nendawo nenkulu enomkhiqizo wansuku zonke ongu-100-500t, ongasetshenziswa njengemishini yokucwenga eyinhloko noma imishini yokucwenga yokuqeda.
• Amabanga ephepha akhethwayo: Iphepha lesiko (iphepha lokubhala, iphepha lokunyathelisa), iphepha lokupakisha (ibhodi eliphakathi, i-corrugating medium), iphepha lezicubu, njll., elifaneleka kakhulu emikhiqizweni enezidingo eziphezulu zamandla okubopha i-fiber kanye nokufana kwephepha.
• Iziphakamiso Zokusetshenziswa: Lapho kucutshungulwa i-pulp yephepha elingcolile, kufanele kunikezwe kuqala ama-disc e-alloy aphezulu amelana nokuguguleka ukuze kuncishiswe ukuguguleka kwemishini okubangelwa ukungcola; lapho kukhiqizwa iphepha lokupakisha elinamandla aphezulu, inqubo yokucwenga ukuhambisana okuphakathi (ukuhlushwa okungu-8%-12%) ingasetshenziswa ukuthuthukisa izinga le-fibre fibrillation; xhuma nohlelo lokulawula oluphakathi lomugqa wokukhiqiza ukuze kufezwe ukwenziwa ngcono okuxhumene kwamapharamitha okucwenga kanye nezinqubo zokwenza iphepha.
