Bhandi rakakomberedzwa nemafirita acuum akaumbwa senge bhandi rakakura rebhandi. Iyo yakakwira-yekubudirira yekufemera mudziyo unoshandisa iyo gravity uye vacuum yekukanda simba reiyo slurry kuti iwane kupatsanurana kwakasimba. Iyo yakave ichishandiswa zvakanyanya nekuda kwezvakanaka zvakanakira maererano nekugadzirwa kwekugadzira, kushambidza kushanda uye kuridza mari. Zvigadzirwa zvakagadzirwa muBritain, United States, iyo Soviet Union, Japan uye dzimwe nyika dzine ruzivo rwakakwana rwe 185 m2 . China yakagadzira inopfuura makumi mashanu yakatwasuka belt vacuum mafirita, uye 20 m 2 iri mune maitiro ekugadzira. Zvinokuvadza zvikuru zverudzi urwu rwefaira ndirwo rutsoka rukuru uye rakanyanya kudyara. Mukuwedzera, neAcuum Filtration, iyo firita cake yekunyorova yakaoma kuderedza.
Kune akawanda marudzi emakona akaomeswa ebhandi vacuum mafirita, uye Fig. 1 Mumwe wavo. Iyo belt belt mhando vacuum firita inosiyana kubva kune bhandi conveyor mune iyo yakafukidzwa nejira refaira pane tepi, uye maviri anoomerera panguva imwe chete. Iyo tepi ine huwandu hwenzvimbo yakatwasuka uye yakatwasuka grooves, yakadai sepachena yemuchina wekucheka wefaira, uye gomba rinobuda mumvura pakati pe chute (Groove). Munguva yekushanda, eyelet inotaura neVaCuum Pumping Tangi pazasi iyo. Nekuda kweiyo vacuum, iyo jira rekucheka rakashambidzwa pamusoro pe tepi, uye iyo filtrate inoyamwa kubva kune iyo orifice iri mucuum inogamuchira, uye yakasara yakasara yakasara pane belt pamusoro. Kudzoreredza zvakare iyo vacuum, kuyamwa iyo cake cake uye ramba uchifambira mberi, kuti kutenderera ukudzokororwa.
Mufananidzo 2 ndeye bhandi yebhandi neine kudzvinyirira belt mudziyo. Iro jira rechiruva riri zvese svutugadzike uye bhandi rinoshandura, uye jira rekucheka rakagadzirwa nePolyster fiber uye polypropylene. Iyo yekudyisa uye yefaira cake discharge inoenderera mberi, asi vacuum inopinda. Iyo vacuum filter disc kudzorera. Sezvo ma fiber siber anoshandiswa sediki svikiro, svikiro rinogona kunge rakanyatsobatanidzwa nedhodhi rechisimba mushure mekudya, uye mhepo iri nyore kwazvo kuve nguva yekufamba, uye degree rakakwira rinogona kuwanikwa. Jira rekucheka riri nyore kutsiva. Iko hakuna kupokana kwerudzi pakati pejira rekufa uye iyo faira disc panguva yekudyidzana kwechiitiko. [Tevere]
Mufananidzo 3 is reel vacuum filter. Iyo firita yakaiswa pane huwandu hwehuwandu hwehuwandu hwakareba Iyo yekunyepedzera tube inodzingwa nehurongwa hunodzoreredzwa. Kuburikidza nehurongwa hwekuparadzira musoro, iyo firita yakadhindwa pane imwe nzvimbo mune imwe neimwe kutenderera, uye keke yefaira yakadzingwa pane imwe chinzvimbo. Rudzi urwu rwemidziyo yakakodzera kurapa iyo slurry ine hombe zvidimbu uye zvakaoma kufefetera nedhisheni yedhiramu, uye machira efaira anogona kungogezwa kune rimwe divi, nyore kuvhara, uye keke yefaira yakadzingwa. Zvinetso, dzimwe nguva zvinoda kuwedzera mudziyo wekudzosera kumashure. Sezvo iyo Dhawa Yakashandisa Chisimbiso Chekubatanidza maviri, mukana weVaCuum kubhururuka mune yese system inowedzera, saka chimiro chakaomarara.
Mufananidzo 4 inhetere yefaira yefaira. Iyo yakadzika yeAngular Filter Bhandi uye jira refaira rakamisikidzwa pane vaviri vebhandi, uye bhandi refaira uye jira refaira rinofamba panguva imwe chete. Chikamu chepamusoro imanidzo-senge chegumi chegumi chakagadzirwa neyekupaza kwejira rekupfekedza zvichiteerana. Munguva yekufambiswa mberi kwekufamba, filtoration, kugeza, kuoma, uye zvakadai zvakaitwa nekubatwa neVaPuum. Mushure mekupedza maitiro akasiyana-siyana, bhandi refaira, jira refaira uye jira rekufa rakaparadzaniswa nevari nekuvhuna kumashure kune chinzvimbo chekutanga. Sezvo iyo mvura ikazadza fara yefaira, kuderedzwa kweVaCuum kwakakonzerwa nekusvina kweiyo slurry chikafu uye kusanganisa kwekushambidza mvura uye iyo filtrate nekuda kwekudzokera kwekushambidza mvura inodzivirirwa. Chishandiso chiri nyore mukuvaka uye bhandi refaira harina kupfekwa zvakanyanya. [Tevere]
Mufananidzo 5 ndeye yakawanda-vacuum bhokisi bhandi bhandi. Kuwanda kweVa Vacuum Bhokisi rakarongedzwa mufurati, uye mativi maviri ePuum Bhokisi anowedzera kumusoro kuti aumbe bhandi, uye bhokisi refirita rine bhandi rekutsigira remucheka wejira refaira. iyo yakafukidzwa nemucheka wefaira une machira efaira akakura kupfuura mbichana mbichana, kuti mativi maviri emachira ejira akasimbiswa nemativi maviri ebhokisi rePuum, uye mushure mekudyara pamucheto wemuchina . . Chimiro chiri nyore kwazvo.
