Enkambisweni yomkhakha wokwenza amaphepha oguqukayo uye esivinini esikhulu kanye nokucwengisiswa, ingxenye yokomisa, njengesixhumanisi esibalulekile esinquma ikhwalithi yephepha kanye nokusebenza kahle kokukhiqiza, ayikaze iyeke ukuphindaphinda ubuchwepheshe bayo bemishini. Nakuba amasilinda okomisa ngomusi wendabuko angahlangabezana nezidingo eziyisisekelo zokomisa, avame ukuba nezinkinga ezifana nokuphaphatheka kwephepha, ukushwabana, kanye nokuphuka kwezimo zokukhiqiza ngesivinini esikhulu, okwenza kube nzima ukuzivumelanisa nezidingo zokukhiqiza zemikhiqizo yephepha ephansi nephezulu. Ngokuphikisana nalesi sizinda, kuye kwavela ama-VAC dryer rolls (aziwa nangokuthi ama-Vac rolls, okungukuthi, ama-vacuum dryer rolls) akhona. Ngemisebenzi yawo ehlukile yokumunca i-vacuum kanye nokomisa okusizayo, abe yimishini eyisisekelo yokusekela esigabeni sokomisa semishini yephepha eshesha kakhulu, enikeza ukwesekwa okubalulekile kokuthuthukisa ikhwalithi kanye nokusebenza kahle embonini yokwenza amaphepha.

Ama-dryer roll e-VAC awazona izingxenye zokushisa nokomisa zendabuko, kodwa imishini yokuzinzisa iwebhu yephepha esheshayo kanye neyokusiza yokomisa esebenza ngokubambisana nama-cylinder omisa ngomusi. Asetshenziswa kakhulu ekucushweni kokomisa ngocingo olulodwa kwemishini yephepha esheshayo, futhi avame ukutholakala emigqeni yokukhiqiza yephepha lamasiko, iphepha elimboziwe, ikhadibhodi elimhlophe, kanye nephepha eliyisisekelo elinoketshezi oluncane. Ngokungafani nendlela yokusebenza yama-cylinder omisa ngomusi wendabuko athembele ekuhlinzekweni kwangaphakathi komusi ukuze ahlinzeke ngokushisa okomisa, ama-dryer roll e-VAC afinyelela ukuzinzisa kwewebhu yephepha ngokumuncwa kwengcindezi okungekuhle, futhi ngesikhathi esifanayo asiza ekusheshiseni ukukhishwa komoya omanzi, ngokuthuthukisa ngokungaqondile ukusebenza kahle kokomisa okuphelele, kwakha uhlelo lokomisa oluhlanganisiwe "lokuzinzisa iwebhu yokushisa + iphepha".

Ngokuphathelene nomklamo wesakhiwo, ama-VAC dryer roll ahlukaniswe kakhulu ngezinhlobo ezimbili ukuze avumelane nesivinini semoto esihlukene kanye nezidingo zokukhiqiza. Phakathi kwazo, i-Vac roll enezimbobo ayidingi ibhokisi le-vacuum elakhelwe ngaphakathi. Ubuso be-roll bunikezwa imifantu engu-5mm ububanzi kanye no-4mm ukujula, kanti imifantu emincane isatshalaliswa phansi kwemifantu, enemifantu eminingi emaphethelweni ukuze kube lula ukufaka intambo. Ingakhiqiza izinga le-vacuum elingaba ngu-2kPa uma ifaniswa nebhokisi elivuthela umoya, futhi izinga lokuvula lilawulwa ku-0.1% ~ 0.4%, okwenza kube nokubopha kwewebhu yephepha ngokusebenzisa ingcindezi engemihle yokugeleza komoya. Isakhiwo sayo silula, sifanele ukukhiqizwa komshini wephepha ophakathi nendawo kanye nesivinini esikhulu. Olunye uhlobo i-Vac roll yohlobo lwebhokisi le-vacuum elakhelwe ngaphakathi, elihlonyiswe ngemifantu enezinyathelo eziqondile noma imifantu eqinile egobolondweni le-roll, kanye negumbi le-vacuum elilungisekayo ngokwebubanzi obungaphakathi, elixhunywe ngqo kuphampu ye-vacuum. Inezinga eliphezulu le-vacuum kanye nokulawula okunembe kakhudlwana, okwenzelwe ngokukhethekile imishini yephepha enesivinini esikhulu kakhulu enejubane elingaphezu kuka-1000m/min, engabhekana ngempumelelo nenkinga yokuzinza kwewebhu yephepha ngaphansi kwezimo zokusebenza ezimbi kakhulu. Kweminye imigqa yokukhiqiza ephezulu, ama-Vac rolls nama-dryer cylinders akha isilinganiso esinembile. Isibonelo, umshini wephepha wokunyathelisa wezinga eliphezulu onomkhiqizo waminyaka yonke wamathani angu-130,000 unesigaba sokomisa esakhiwe ngama-cylinders angu-29 okomisa ngomusi kanye nama-Vac rolls amaningi anobubanzi obungu-1500mm. Umugqa ongezansi wama-dryer cylinders wendabuko ushintshwa ngokuphelele ama-Vac rolls, okwenza kube nokukhiqizwa okuqhubekayo okuphumelelayo ngaphandle kokufaka izintambo futhi kuthuthukise kakhulu ukuzinza kokusebenza.

Inani eliyinhloko lama-VAC dryer rolls livela esimisweni sawo sokusebenza kwesayensi kanye nezinzuzo zokusebenza ngaphansi kwezimo zokusebenza zesivinini esikhulu. Ekukhiqizweni kwangempela, umugqa ongaphezulu wama-cylinder omshini wokomisa umusi unesibopho sokunikeza ukushisa ukuze kuphele umswakama kuwebhu yephepha, kuyilapho umugqa ongezansi wama-VAC dryer rolls umunca ngokuqinile iwebhu yephepha ebusweni bentambo eyomile ngokucindezela okungekuhle, kususe ngempumelelo amandla e-centrifugal akhiqizwa ukusebenza kwesivinini esikhulu, futhi kuxazulule ngokuyisisekelo izindawo ezibuhlungu embonini njengokuphaphaza komphetho wewebhu yephepha, ukushwabana, nokuphuka. Ngesikhathi esifanayo, ukuhamba komoya ephaketheni lomoya kudonswa emigodini yama-roll, kusheshiswe ukukhishwa komoya omanzi, kuphule ungqimba lokugcina umoya omanzi ebusweni bewebhu yephepha, futhi kuthuthukise ngokungaqondile izinga lokomisa. Esigabeni sokuhlanganisa izintambo, ukwakheka kwemigodi emide emaphethelweni kungathuthukisa umphumela wokumunca, kuthuthukise kakhulu izinga lempumelelo yokuhlanganisa izintambo, futhi kufinyeze isikhathi sokuhlanganisa izintambo. Icala lokuguqulwa komshini wephepha we-PM15 kaLee & Man Paper liqinisekisa ngokugcwele lokhu. Ngemva kokuguqula amasilinda omshini wokomisa aphindwe kabili abe amasilinda omshini wokomisa aphindwe kabili futhi wawathuthukisa abe ama-Vac roll, kuhlanganiswe namabhokisi okuqinisa alungiselelwe kanye nemishini yokungenisa umoya ephaketheni, izinga lokuphuka kwewebhu yephepha lehlisiwe ngo-60%, isikhathi sokungasebenzi esingahleliwe sehlisiwe ngo-30%, kanti lapho kukhiqizwa iphepha eliyisisekelo eliyi-corrugating paper elingu-70~90g/m² ngesivinini esingu-1000m/min, isilinganiso sokuphuka kwephepha ngenyanga sasiphindwe kayishumi kuphela, kanti ukusebenza kahle kokukhiqiza kwanda ngo-3%.

Uma kuqhathaniswa namasilinda omshini wokomisa wendabuko, indawo yokusebenza kwama-VAC dryer rolls ithambekele kakhulu ekuzinzisweni kwewebhu yephepha kanye nokomisa okusizayo, futhi lokhu kokubili kwakha ubudlelwano obuhambisanayo nobuhlelekile. Ngokuphathelene nokunikezwa komthombo wokushisa, ama-VAC dryer rolls awanayo isakhiwo sokushisa esakhelwe ngaphakathi futhi athembele ngokuphelele ekucindezelweni okungekuhle ukuze asebenze, kuyilapho amasilinda omshini wokomisa we-steam esebenzisa umusi njengomthombo wokushisa futhi enza imisebenzi yokudlulisa ukushisa eyinhloko kanye nokomisa; maqondana nesakhiwo sobuso, ama-VAC dryer rolls asebenzisa imiklamo enemiphetho noma ebholiwe, kuyilapho amasilinda omshini wokomisa we-steam ikakhulukazi enezindawo ezibushelelezi ze-chrome-plated noma zensimbi ephonswe; maqondana nokugxila kokusebenza, ama-VAC dryer rolls agxila ekuzinzisweni kobubanzi bewebhu yephepha, ukususwa komswakama okusizayo, kanye nokunciphisa amaphutha ephepha, kuyilapho amasilinda omshini wokomisa we-steam agxila ekudlulisweni kokushisa okuphumelelayo ukuze kuqedwe ukuhwamuka okuyinhloko komswakama kuwebhu yephepha. Ngokuphathelene nomthamo wokomisa, umthamo wokomisa we-VAC dryer roll eyodwa ulinganiselwe, futhi cishe ama-Vac rolls angu-2~3 alingana nesilinda esisodwa somshini wokomisa esijwayelekile. Ngakho-ke, ekusetshenzisweni okungokoqobo, kuyadingeka ukufanisa ngokwesayensi inani lama-Vac rolls nama-steam dryer cylinders ngokwejubane lemoto kanye nenani lephepha ukuze kufezwe ibhalansi phakathi kokusebenza kahle kanye nezindleko.

Ngaphansi kwesizinda sokuthuthuka kwesu "lekhabhoni ephindwe kabili" kanye nokuguqulwa okuhlakaniphile nokonga amandla embonini yokwenza amaphepha, ukusetshenziswa kwama-dryer roll e-VAC nakho kudinga ukucabangela ukulawula ukusetshenziswa kwamandla kanye nokwenza ngcono ukulungiswa. Ama-dryer roll e-VAC adinga ukusekela izinhlelo ze-vacuum kanye nokungenisa umoya, futhi uma kuqhathaniswa nokulungiswa kokwejwayelekile kokomisa, izindleko zawo zokusetshenziswa kwamandla kanye nokugcinwa ziphakeme kancane, kodwa ukonga amandla kanye nokunciphisa ukusetshenziswa kungatholakala ngokwenza ngcono ubuchwepheshe. Isibonelo, i-Lee & Man Paper ithuthukise ibhokisi le-vacuum le-SymRun ngesikhathi sokuguqulwa, yanciphisa umthwalo womoya womoya ngo-30% ngenkathi ithuthukisa izinga le-vacuum; i-Valmet Finland ilungise isikhala phakathi kwama-Vac rolls nama-dryer cylinders ngokuskena kwe-3D kanye nokwenza imodeli, yandisa i-engeli yokugoqa i-dryer yewebhu yephepha, yanciphisa inani lama-blower namapayipi omoya, futhi yehlisa izindleko zokusetshenziswa kwamandla kanye nokugcinwa. Ekulungisweni kwansuku zonke, kuyadingeka ukuhlanza njalo imigodi kanye nemisele ye-Vac roll ngomoya ocindezelwe ukuze kuvinjelwe ukuvaleka, hlola ukusebenza kwe-vacuum sealing kanye nokushisa kokuthwala ngesikhathi esifanayo, futhi ulawule izinga le-vacuum ngaphakathi kwezidingo zenqubo. Ukuhlanganisa nohlelo lokungenisa umoya olusebenza kahle ephaketheni kanye nezinhlelo zokupholisa kungathuthukisa kakhulu ukusebenza kahle kokomisa futhi kunciphise ukusetshenziswa komusi.

Ngokuthuthukiswa okuqhubekayo kobuchwepheshe bemishini yephepha esheshayo kanye nesidingo esikhulayo semikhiqizo yephepha ephezulu, ukuphindaphinda kobuchwepheshe be-VAC dryer rolls nakho kuzoqhubekela phambili ekuqondeni, ukulondolozwa kwamandla, kanye nobuhlakani. Esikhathini esizayo, ngosizo lobuchwepheshe obusezingeni eliphezulu njengokulingisa kwe-CFD kanye nokubala ngezinombolo, ukwakheka kwembobo kanye nesakhiwo segumbi le-vacuum se-Vac rolls kungathuthukiswa kakhulu ukuze kuthuthukiswe ukunemba kokulawula ingcindezi okungekuhle kanye nezinga lokubopha iphepha lewebhu; kuhlanganiswe nokuzwa okuhlakaniphile kanye nokuhlaziywa kwedatha enkulu, ukulawulwa okunamandla kwe-vacuum degree kungafezeka ukuze kuvumelane nezidingo zokukhiqiza zezinhlobo ezahlukene zephepha kanye nesivinini sezimoto ezahlukene; ngesikhathi esifanayo, ngokuthuthukiswa kwezinto kanye nokwenza ngcono isakhiwo, ukusetshenziswa kwamandla kwemishini kanye nokuguguleka kungancishiswa, futhi impilo yesevisi ingandiswa. Njengethuluzi "lokuzinzisa ikhwalithi" lezinhlelo zokomisa iphepha ezisheshayo, i-VAC dryer rolls ayixazululi nje kuphela izindawo eziningi ezibuhlungu zokucushwa kwendabuko kokomisa ngaphansi kwezimo zokusebenza ezisheshayo, kodwa futhi isiza amabhizinisi okwenza iphepha ukuthuthukisa ikhwalithi yomkhiqizo kanye nokwenza ngcono ukusebenza kahle kokukhiqiza, kufaka umfutho omusha ekuthuthukisweni kwekhwalithi ephezulu yomkhakha wokwenza iphepha.
