Air slide chute conveying system inzira yakanyanyisa ye airtight pneumatic conveying nzira, iyo inoshandisa yakaderera-kudzvanywa mweya kuti upfuure nemumhepo inotsvedza machira kuzadzisa chinangwa chehupfu / zvidimbu zvinofambisa.
Mhepo yakamanikidzwa inopararira mushure mekupfuura nepakati pemhepo inotsvedza jira uye inopinda yakatenderedza zvimedu, izvo zvinokunda kushorwa kwezvimedu nemhepo inotsvedza machira, kuitira kuti zvimedu zvive kune fluidization mamiriro semvura, zvino inoyerera negiravhiti mutangi.
Kuenzaniswa nemamwe masisitimu ekufambisa emhepo, mhepo inotsvedza chute system ine zvimiro zvepasina zvinotenderera, pasina ruzha, kushanda kuri nyore uye manejimendi, uremu hwemidziyo yakareruka, kuderera kwesimba rekushandisa, chimiro chakareruka, hombe yekufambisa, uye nyore kushandura nzira yekufambisa. . Zvishandiso zvehupfumi zvakanyanya zvekufambisa zvinhu zvehupfu uye granular bulk solids.

1.Kuvaka uye kugadzira
1.1, kuvaka
Mhepo inotsvedza chute inowanzorerekera zvishoma kune yakachinjika ndege, uye chikamu chinowanzo gadzirwa chine sikweya.
Iyo mhepo inotsvedza chute yakasanganiswa neyekumusoro chute uye yepasi chute, machira emhepo anotsvedza akaiswa pakati kuti aite mhepo inotsvedza chute ine makamuri maviri, iyo yehupfu inoyerera mukamuri yepamusoro iyo yakadana zvinhu chamber uye mweya wakatsikirirwa muzasi. kamuri iyo yakadana kamuri yemhepo.
Iyo mhepo yakamanikidzwa inosefa uye kuderedzwa kune imwe kudzvanywa sekukumbirwa, wozopinda mukamuri yemhepo kuburikidza nepombi yemhepo, wozopinda mukamuri yemidziyo kuburikidza nemhepo inotsvedza machira.
Kuyerera kwemhepo kunopfuura nemumhepo inotsvedza machira uye inomisa hupfu kuti ive iyo yakanyungudika mamiriro, kushandura friction angle yehupfu uye kunyange kuita kuti zvinhu zvisabatane nemhepo inotsvedza machira. Zvisinei, kuyerera kwechigadzirwa chacho kunokurumidza, asi kupikisa kupikisa nemhepo slide machira iduku zvikuru.
Pakupedzisira, mhepo yakamanikidzwa yakasanganiswa nehupfu inoburitswa mumhepo kuburikidza nesefa, uye zvinhu zvehupfu zvinoyerera zvichibuda nepachiteshi chekuburitsa chemhepo inotsvedza chute.
Izvo zvigadziriso zvemhepo inotsvedza chute yesarudzo inogona kuve kabhoni simbi, aluminium alloy, simbi isina tsvina kana isiri-simbi zvinhu.
Mhepo inotsvedza machira anogona kugadzirwa nezvinhu zvakasiyana, sekotoni, polyester, aramid, kunyange fiber girazi, basalt uye zvichingodaro. Dzimwe nguva zvakare inogona kugadzirwa ine microplates, senge porous ceramic mahwendefa, sintered porous epurasitiki mahwendefa uye zvichingodaro.

1.2, dhizaini uye kuverenga.
Izvo zvakakosha zviri mukati medhizaini uye kuverenga kwemhepo inotsvedza chute yekufambisa sisitimu zvinosanganisira kuyambuka-chikamu saizi yechute, chinhambwe chekufambisa, kona yekurerekera, simba remhepo, kushandiswa kwemhepo, uye kugona kwekufambisa.
Kuti uite kuti zvinhu zvifambe zvakajairwa uye zvakadzikama mumhepo inotsvedza chute, mamiriro anodiwa ndeekuti mweya unofanirwa kunge uine kumwe kudzvanywa uye kuyerera kwakakwana.
1.2.1, dhizaini yemhepo
Kudzvinyirirwa kwemhepo kunoenderana nekupokana kwemhepo inotsvedza machira uye kureba kwezvinhu zviri kuendeswa mukamuri yehupfu.
Iwo machira emhepo anotsvedza anofanirwa kuve nekupokana kwakakwana kuti ave nechokwadi chekugovera kwemhepo mukamuri yemidziyo zvakaenzana.
The air pressure inogona kusarudzwa neinotevera formula:
P=P1+P2+P3

P1 ndiko kuramba kwemhepo inotsvedza machira, unit iKPa;
P2 inopikisa zvinhu zvehupfu, chikwata iKPa;
P3 ndiko kushorwa kwemitsara yepombi.
Zvinoenderana nezvakaitika, iyo air press P inogara ichisarudza pakati pe3.5 ~ 6.0KPa, kana yakagadzirwa, kunyanya zvichienderana ne5.0KPa.

Mhepo inotsvedza jira chikamu chakakosha chemhepo slide chute conveying system / pneumatic conveying chute, sarudzo yakakodzera yemucheka wemhepo inotsvedza ndiyo yekutanga yekushanda kwakakwana kwemhepo slide chute conveying system.
Machira emasiraidhi emhepo anofanirwa kuve nedivi repore, kugovera kwakafanana kwepateni yekuruka, kupenya kwemhepo, uye saizi yepore inofanirwa kunge iri diki pane dhayamita yezvikamu zvehupfu huri kufambiswa kudzivirira machira emhepo anotsvedza kuvharika. .
Pasi pemamiriro akatsiga ekufambisa, kupokana kwemhepo/kudonhedza kudonha kwemhepo kunotsvedza machira kunofanirwa kunge kwakakura kudarika kupikisa kwemhepo / kudonhedza kudonhera pamusoro pehupfu huri kufambiswa, uye kudonhera kudonha kwemhepo kunotsvedza machira kunofanirwa kuita yunifomu, kana mhepo. slide chute convey system inogona nyore kuvharika nekuda kwedambudziko remhepo inotsvedza machira, saka frequency yekuchinja ichave yakanyanya kukwirira.

Mhepo inotsvedza machira kubva kuZonel Filtech, tinovimbisa kuita kwakanaka mu12month mushure mekuiswa kana 18month mushure mekusununguka, asi kana yakanyatsoshanda, kana mamiriro ekushanda akanaka, kushanda kwakanaka kwemhepo inotsvedza machira kubva kuZonel Filtech kunyange inogona kumira kupfuura. 4 makore, ayo anogona kuchengetedza mari yakawanda yekuchengetedza uye nguva yevatengi vedu.

1.2.2, vhoriyamu yekushandiswa kwemhepo yakamanikidzwa.
Iyo yakamanikidzwa mhepo yekushandisa vhoriyamu yemhepo inotsvedza chute inofambisa system ine hukama neizvi zvinotevera zvinhu:
Hunhu hwemuviri hwezvinhu, saizi yemuchinjikwa-chikamu uye kureba kweiyo yekuwachisa, kureba kwehupfu hwehupfu, kurerekera kweiyo launder, nezvimwe.
Kuti udzivise machira emhepo anotsvedza kuvharika, mweya unopihwa unofanirwa kuderedzwa uye kubviswa mafuta.
Kushandiswa kwemhepo kwemhepo inotsvedza inofambisa system/pneumatic conveying chute inogona kuverengerwa neinotevera formula:
Q=qWL

"q" ndiyo mhepo inoputika yemucheka wemhepo inotsvedza, chikwata chiri m3 / m2.h, sezvinowanzoitwa "q" tinosarudza 100 ~ 200;
W ndiyo hupamhi hwehupfu hunoyerera chute;
L ndihwo hurefu hwehupfu hunoyerera chute.

1.2.3, kugona kwemhepo inotsvedza chute inofambisa hurongwa
Kugona kwemhepo inotsvedza chute inofambisa sisitimu yakaitwa nezvinhu zvakawanda, iyo fomula inogona kunge inotevera:
G=3600 X S.ρ.V = 3600 X Whρ.V

S inzvimbo yechikamu chehupfu mumhepo inotsvedza chute, kubatana ndeye m2;
P is air density yezvinhu zvakanyungudika, unit is kg/m3;
V ndiyo hupfu inoyerera kumhanya, unit is m/s;
W ndiwo upamhi hwemukati hwemhepo inotsvedza chute;
H ndiko kureba kwemukati kwemhepo inotsvedza chute.

Zvinoenderana nemusimboti wemagetsi mechanics, kuyerera kwehupfu mumhepo inotsvedza chute yakafanana nekudzikama kuyerera kwemvura mugero rakashama, saka kuyerera kwehupfu hwehupfu hunoenderana nekurerekera kwemhepo inotsvedza chute. pamwe nehupamhi hwemhepo inotsvedza chute uye kureba kwezvinhu zvesimba mumhepo slide chute, saka:
V=C√(Ri)

C inonzi Chezy coefficient, C=√(8g/λ)
R is hydraulic radius, unit m;
“i” ndiko kurerekera kwemhepo inotsvedza chute;
"λ" ndiyo friction coefficient.

Iko kurerekera kwemhepo inotsvedza chute semazuva ese sarudza pakati pe10% ~ 20%, kureva 6 ~ 11 dhigirii maererano nezvinodiwa;
Kana hupfu hwehupfu hurefu huri H, senguva dzose mhepo inotsvedza chute yakafara W=1.5H, chikamu chehupfu hurefu h i0.4H.

2. Mhedziso.
Iyo mhepo inotsvedza chute inotakura system / pneumatic conveying chute inoshandisa yakaderera-kudzvanywa mweya kuyerera zvinhu, uye inoshandisa iyo yakarerekera chikamu simba kufambisa zvinhu kumberi. Inogona kushandiswa zvakanyanya mukutakurwa kwemhando dzakasiyana-siyana dzemhepo-inopindika, yakaoma hupfu kana granular zvinhu zvine particle size pazasi 3 ~ 6mm.
Iyo ine mabhenefiti ehukuru hwekutakura huwandu, kunyanya kuderera kwesimba rekushandisa, uye huwandu hwayo hwekushandisa huri kuwedzera zvishoma nezvishoma.
Asi nekuda kwemhepo inotsvedza chute inoiswa zvisingaite, kureba kwekufambisa kunoganhurwa nekudonha, zvakare haina kukodzera kukwidza kumusoro, saka kushandiswa kwemhepo inotsvedza chute inotakura system/pneumatic conveying chute ine painogumira.
