Air slide chute conveying system ndi njira yopitilira muyeso yolumikizira mpweya, yomwe imagwiritsa ntchito mpweya wocheperako kuti udutse nsalu za slide kuti zikwaniritse cholinga cha ufa / tinthu tating'ono.
The wothinikizidwa mpweya amabalalitsa pambuyo podutsa mpweya Wopanda nsalu ndi kulowa mozungulira particles, amene amagonjetsa kukana particles ndi mpweya Wopanda nsalu, kuti particles kukhala fluidization zinthu ngati madzi, ndiye umayenda ndi mphamvu yokoka mu thanki.
Poyerekeza ndi makina onyamulira makina, makina opangira ma slide chute okhala ndi mawonekedwe osazungulira, opanda phokoso, magwiridwe antchito ndi kasamalidwe koyenera, kulemera kwa zida zopepuka, kugwiritsa ntchito mphamvu zochepa, mawonekedwe osavuta, mphamvu yayikulu yotumizira, komanso yosavuta kusintha njira yotumizira. . Zida zotsika mtengo kwambiri zotumizira zinthu zaufa ndi zolimba zochulukirapo.

1.Kumanga ndi kupanga
1.1, kumanga
Mpweya wa slide chute nthawi zambiri umakhala wolunjika pang'ono ku ndege yopingasa, ndipo gawolo nthawi zambiri limapangidwa ndi masikweya.
Mpweya wotsetsereka wa chute wophatikizidwa ndi chute chapamwamba ndi chute chapansi, nsalu zotchingira mpweya zimayikidwa pakati kuti mpweya wotsetsereka ndi zipinda ziwiri, zinthu za ufa zikuyenda m'chipinda chapamwamba chomwe chimatcha chipinda chakuthupi ndi mpweya woponderezedwa kumunsi. chipinda chomwe chinatcha chipinda cha mpweya.
The wothinikizidwa mpweya adzasefedwa ndi decompressed kwa kuthamanga ena monga anapempha, ndiye kulowa mpweya chipinda kudzera mpweya chitoliro, ndiyeno kulowa mu chipinda zinthu kudzera mpweya Wopanda nsalu.
The mpweya kudutsa mu mpweya Wopanda nsalu ndi suspends zinthu ufa kuti fluidized boma, kusintha mikangano ngodya wa zinthu ufa ndipo ngakhale kupanga zinthu kusakhudzana ndi nsalu Wopanda mpweya. Komabe, kuthamanga kwa zinthuzo kumathamanga, koma kukaniza kosagwirizana ndi nsalu za slide za mpweya ndizochepa kwambiri.
Pomaliza, mpweya wophatikizika wophatikizidwa ndi zinthu za ufa udzatulutsidwa mumlengalenga kudzera mu fyuluta, ndipo zinthu za ufa zimatuluka kudzera padoko lotayira la chute ya mpweya.
Zipangizo zamapangidwe a chute ya slide ya mpweya zomwe mungasankhe zitha kukhala chitsulo cha carbon, aluminiyamu aloyi, chitsulo chosapanga dzimbiri kapena zinthu zopanda zitsulo.
Nsalu zojambulidwa ndi mpweya zimatha kupangidwa ndi zinthu zosiyanasiyana, monga thonje, polyester, aramid, ngakhale galasi la fiber, basalt ndi zina zotero. Nthawi zina amathanso kupangidwa ndi ma microplates, monga ma porous ceramic mbale, sintered porous pulasitiki mbale ndi zina zotero.

1.2, kapangidwe ndi kuwerengera.
Zomwe zili zofunika kwambiri pakupanga ndi kuwerengera makina otumizira ma slide chute ndi monga kukula kwa magawo a chute, mtunda wotumizira, ngodya yolowera, kuthamanga kwa mpweya, kugwiritsa ntchito mpweya, komanso mphamvu yotumizira.
Kuti zinthuzo ziziyenda bwino komanso mokhazikika mu chute ya slide ya mpweya, chofunikira ndikuti mpweya uyenera kukhala ndi kuthamanga kwina komanso kuthamanga kokwanira.
1.2.1, mapangidwe amphamvu ya mpweya
Kuthamanga kwa mpweya kumagwirizana ndi kukana kwa nsalu za slide za mpweya ndi kutalika kwa zinthu zomwe zimaperekedwa mu chipinda cha ufa.
Nsalu za slide za mpweya ziyenera kukhala ndi kukana kokwanira kuti zitsimikizire kugawidwa kwa mpweya mu chipinda chakuthupi mofanana.
Kuthamanga kwa mpweya kungadziwike ndi njira iyi:
P=P1+P2+P3

P1 ndi kukana kwa nsalu za slide, unit ndi KPa;
P2 ndi kukana zinthu za ufa, gawo ndi KPa;
P3 ndi kukana kwa mizere ya mapaipi.
Malinga ndi zomwe zachitika, makina osindikizira a mpweya P nthawi zonse amasankha pakati pa 3.5 ~ 6.0KPa, pamene amapangidwa, makamaka malinga ndi 5.0KPa.

Nsalu ya slide ya mpweya ndi gawo lofunika kwambiri la makina oyendetsa mpweya / pneumatic conveying chute, njira yoyenera ya nsalu ya slide ya mpweya ndiyomwe imapangitsa kuti makina oyendetsa mpweya azikhala bwino.
Nsalu za slide za mpweya ziyenera kukhala ndi mbali ya pore, kugawa yunifolomu kwa chitsanzo choluka, mpweya wabwino, ndi kukula kwa pore kuyenera kukhala kocheperapo kusiyana ndi kukula kwa tinthu tating'onoting'ono tomwe timatulutsa kuti tipewe nsalu za slide kuti zitsekedwe. .
Pansi pamikhalidwe yokhazikika yotumizira, kukana kwa mpweya / kutsika kwa mpweya pansalu za slide kuyenera kukhala kwakukulu kuposa kukana kwa mpweya / kutsika kwamphamvu pazinthu zaufa zomwe zimaperekedwa, ndipo kutsika kwamphamvu kwa nsalu zowulutsa kuyenera kukhala kofanana, kapena mpweya. slide chute convey system ingakhale yosavuta kutsekedwa chifukwa cha vuto la nsalu za slide, kotero kusintha kwafupipafupi kudzakhala kokwezeka kwambiri.

Nsalu zojambulidwa ndi mpweya zochokera ku Zonel Filtech, timatsimikizira kuti zikuyenda bwino mu 12month pambuyo pa kukhazikitsidwa kapena 18month pambuyo pobereka, koma pamene ntchito yeniyeni, ngati ntchitoyo ili yabwino, ntchito yabwino ya nsalu za slide kuchokera ku Zonel Filtech ikhoza kuyima kuposa Zaka 4, zomwe zingapulumutse ndalama zambiri zokonzekera komanso nthawi kwa makasitomala athu.

1.2.2, wothinikizidwa mpweya wogwiritsa ntchito.
Kuchuluka kwa mpweya woponderezedwa kwa makina otumizira ma air slide chute kumagwirizana ndi izi:
Zomwe zimapangidwira zakuthupi, kukula kwa gawo ndi kutalika kwa chochapa, kutalika kwa wosanjikiza wa zinthu za ufa, kupendekera kwa chochapa, ndi zina zambiri.
Pofuna kupewa kuti nsalu za slide zisatsekeke, mpweya woperekedwa uyenera kuchotsedwa madzi ndikuchotsa mafuta.
Kagwiritsidwe ka mpweya ka slide conveying system/pneumatic conveying chute ikhoza kuwerengedwa motere:
Q=qWL

"q" ndi mpweya wokwanira wa nsalu yotchinga mpweya, unit ndi m3 / m2.h, monga mwachizolowezi "q" timasankha 100 ~ 200;
W ndi m'lifupi mwa ufa chuma otaya chute;
L ndi kutalika kwa chute ya zinthu za ufa.

1.2.3, mphamvu ya makina otumizira ma slide chute
Kuthekera kwa makina otumizira ma slide chute adachitika ndi zinthu zambiri, chilinganizocho chingakhale chotere:
G=3600 X S.ρ.V = 3600 X Whρ.V

S ndi gawo la gawo la zinthu za ufa mu chute ya mpweya, gwirizanitsani ndi m2;
P ndi kachulukidwe ka mpweya wa zinthu zosungunuka, unit ndi kg/m3;
V ndi ufa umayenda liwiro, unit ndi m/s;
W ndi m'lifupi m'kati mwa chute mpweya slide;
H ndiye kutalika kwamkati kwa chute ya mpweya.

Malingana ndi mfundo ya makina amadzimadzi, kutuluka kwa zipangizo za ufa mu chute ya slide ya mpweya kumakhala kofanana kwambiri ndi kutuluka kwabata kwamadzi mumsewu wotseguka, kotero kuthamanga kwa zinthu za ufa kumagwirizana ndi kutengera kwa chute ya mpweya. komanso m'lifupi mwake slide chute mpweya ndi mphamvu zakuthupi kutalika mu mpweya slide chute, kotero:
V=C√(Ri)

C ndi Chezy coefficient, C=√(8g/λ)
R ndi hydraulic radius, unit m;
"i" ndikupendekera kwa chute ya mpweya;
"λ" ndi friction coefficient.

Kutengera mpweya Wopanda chute mwachizolowezi kusankha pakati pa 10% ~ 20%, mwachitsanzo 6 ~ 11 digiri malinga ndi zofunika;
Ngati ufa chuma chute kutalika ndi H, mwachizolowezi mpweya Wopanda chute m'lifupi W = 1.5H, ufa gawo kutalika H ndi 0.4H.

2.Mapeto.
Mpweya wodutsa chute wotumizira chute / pneumatic conveying chute imagwiritsa ntchito mpweya wocheperako kuti usungunuke zinthuzo, ndipo imagwiritsa ntchito mphamvu yachinthu kusuntha zinthuzo patsogolo. Itha kugwiritsidwa ntchito ponyamula mitundu yosiyanasiyana ya mpweya, ufa wowuma kapena granular ndi kukula kwa tinthu pansipa 3 ~ 6mm.
Ili ndi ubwino waukulu wotumizira mphamvu, makamaka kugwiritsira ntchito mphamvu zochepa, ndipo mawonekedwe ake ogwiritsira ntchito akukula pang'onopang'ono.
Koma chifukwa cha chute ya slide ya mpweya imayikidwa mwachisawawa, mtunda wotumizira umachepa ndi kutsika, komanso siwoyenera kunyamula mmwamba, kotero kugwiritsa ntchito chute ya mpweya / pneumatic conveying chute kuli ndi malire ake.
