Isihlungi se-vacuum evundlile sakhiwe njenge-conveyor enkulu yebhande. Kuyinto esebenza kahle ye- filltration esebenza ngamandla asebenzisa amandla adonsela phansi kanye ne-vacuum suction force ye-slurry ukufezekisa ukuhlukaniswa okuqinile koketshezi. Kusetshenziswe kabanzi ngenxa yezinzuzo zayo ezivelele ngokuya ngomthamo wokukhiqiza, ukugeza kahle kanye nezindleko zokukhiqiza. Imikhiqizo eyenziwe eBrithani, e-United States, iSoviet Union, iJapan namanye amazwe banokucaciswa okuphezulu kuka-185 m2 . I-China ithuthukise izihlungi ze-vacuum ezivundlile ezingaphezu kwama-50, kanti ezingama-20 m 2 zisezinhlelweni zokwakhiwa. Ububi obukhulu balolu hlobo lokuhlunga luyisisekelo esikhulu sezinyawo kanye nokutshalwa kwemali okuphezulu. Ngaphezu kwalokho, ngokuhlunga kwe-vacuum, i-Filter Cake umswakama kunzima ukunciphisa.
Kunezinhlobo eziningi zezihlungi ze-vacuum ezivundlile, kanye Fig. 1 kungenye yazo. Isihlungi se-ruble band hlobo vacuum siyehluka kusuka ku-belt conveyor ngoba simbozwe ngesendlalelo sendwangu yokuhlunga ethepheni, futhi lokhu okubili kusengaphambili ngasikhathi sinye. Iteyipu inobuningi be-grooves eqondile futhi evundlile, njengepuleti lokuhlunga lomshini wokuhlunga, nomgodi okhipha uketshezi phakathi kwe-chute (i-groove). Ngesikhathi sokusebenza, i-eyelet ikhuluma ngethangi lokupompa le-vacuum ngaphansi kwalo. Ngenxa ye-vacuum, i-wave yendwangu yokuhlunga i-adderbed ethepheni, futhi i-filtrate imunca e-orifice esitholweni se-vacuum, futhi izinsalela zokuhlunga zishiywe ekhasini. Phinda uphinde uthole i-vacuum, cela ikhekhe lokuhlunga bese uqhubeka uthuthuke, ukuze umjikelezo uyaphindwa.
Umdwebo 2 uhlaka lwebhande ngedivaysi yebhande lengcindezi. Indwangu yokuhlunga zombili i-medium medium kanye nebhande lokuhambisa, nendwangu yokuhlunga yenziwe nge-polyester fiber ne-polypropylene. Ukuphangwa okuphakelayo kanye nokuhlunga kwekhekhe kuyaqhubeka, kepha i-vacuum iyisikhathi esithile. I-Vacuum Filter Disc Discurates. Njengoba i-fiber yokwenziwa isetshenziswa njengendlela yokuhlunga, i-medium ingahle ifakwe eduze kwi-disc yokuhlunga ngemuva kokondla, futhi umoya kulula kakhulu ukuba ne-airtight, futhi izinga eliphakeme le-vacuum lingatholakala. Indwangu yokuhlunga kulula ukuyifaka esikhundleni. Akukho ukungqubuzana okuhlobene phakathi kwendwangu yokuhlunga ne-disc yokuhlunga ngesikhathi inqubo yokuhlunga yokumunca. [Olandelayo]
Umdwebo 3 yisihlungi se-reel vacuum. Isihlungi sifakwe ngobuningi bamabhande okuhambisa ahlukaniswe kamuva, ngalinye elifakwe ngendwangu yokuhlunga 2, futhi i-filtrate itholwa i-vacuum-i-vacuum-angena ngaphansi kwetay yokuhlunga. I-Outlet Tube ikhishwa yi-hose ethosiwe. Ngokuhambisa ilungiselelo lekhanda, isihlungi sihlungwa endaweni ethile emjikelezweni ngamunye, futhi ikhekhe lokuhlunga likhishwa kwesinye isikhundla. Lolu hlobo lwemishini lufanele ikakhulukazi ukuphatha ama-slurry aqukethe izinhlayiya ezinkulu futhi kunzima ukuhlunga, futhi kungagezwa kaningi, kepha indwangu yokuhlunga ingagezwa kuphela ohlangothini olulodwa, kulula Ukuvimba, futhi ikhekhe lokuhlunga liyakhishwa. Ubunzima, kwesinye isikhathi kudingeka bandise idivaysi yokubuyela emuva. Njengoba i-disc yokuhlunga isebenzisa uphawu lokuxhumeka okubili, amathuba okuvuza kwe-vacuum kulo lonke uhlelo luyanda, ngakho-ke isakhiwo siyinkimbinkimbi.
Umdwebo 4 isihlungi sebhande le-finger. Ibhande lokuhlunga eliphansi lonyaka nendwangu yokuhlunga ifakwe kuma-roller, kanye nebhande lokuhlunga kanye nendwangu yokuhlunga iyahamba ngasikhathi sinye. Ingxenye engenhla iyisitebhisi enjengesitebhisi esenziwe ngezinto ezisetshenziswayo, icindezelwe ngokumelene nendawo engenhla yendwangu yokuhlunga, ifreyimu yokuhlunga kanye nodaka futhi uketshezi lokuhlanza lungafakwa kufreyimu ebekiwe yokuhlunga ngokulandelana. Ngesikhathi sokunyakaza phambili, i-filtration, ukugeza, ukomisa, nokunye okunjalo kwenziwa yi-vacuum suction. Ngemuva kokuqeda izinqubo ezahlukahlukene, ibhande lokuhlunga, indwangu yokuhlunga nohlaka lokuhlunga luhlukaniswe ngokwabo kanye nokubuyisela emuva esimweni sokuqala. Njengoba uketshezi lugcwalisa ifreyimu yokuhlunga, ukuncishiswa kwe-vacuum okubangelwa ukungalingani kokuphakelwa okufushane kanye nokuxutshwa koketshezi lokuwasha kanye ne-filtrate ngenxa yokubuyela emuva koketshezi lokuwasha kuvinjelwe. Idivayisi ilula ekwakheni futhi ibhande lokuhlunga aligqokwa kakhulu. [Olandelayo]
Umdwebo 5 uyisihlungi sebhande le-VULT-Vacuum Box. Kuhlelwa inqwaba yamabhokisi we-vacuum e-vacuum ngohlaka, futhi izinhlangothi zombili zebhokisi le-vacuum zinwetshwa phezulu ukuze zakhe ubambo, futhi ibhokisi ngalinye le-vacuum linebhande lokuhambisa (ibhande lokuhlunga) lokusekela ukunyakaza okude kwendwangu yokuhlunga, okumbozwe ngendwangu yokuhlunga kunendwangu yobubanzi obukhulu kunebhande lokuhlunga, ukuze izinhlangothi zombili zendwangu yokuhlunga zivalwe ngokuqinile nezinhlangothi zombili zebhokisi le-vacuum, futhi ngemuva kokondliwa ekugcineni komshini , ukuwohloka nokugeza kulandelana kwenziwa ngamabhokisi we-vacuum afanele. , Inqubo yokomisa, isikhala phakathi kwesihloko sebhande lokuhlunga ebhokisini lesibili le-vacuum, lingabekwa amathuluzi okulinganisa kanye nemishini yokuhlola yokulinganisa isilinganiso sokudonsa ikhekhe lokuhlunga, okuqukethwe kwensimbi kanye nokuqukethwe kwensimbi . Isakhiwo silula kakhulu.
