100 mesh – 400 ma mesh Chitsulo Ufa Madzi Atomizer Machine

Ufa wokonzedwa ndi vacuum air atomization uli ndi ubwino wa kuyera kwambiri, mpweya wochepa komanso tinthu tating'onoting'ono ta ufa wosalala. Pambuyo pa zaka zambiri zatsopano komanso kusintha, ukadaulo wa vacuum air atomization powder wakula kukhala njira yayikulu yopangira ufa wachitsulo ndi alloy wochita bwino kwambiri, ndipo wakhala chinthu chotsogola chothandizira ndikulimbikitsa kafukufuku wa zipangizo zatsopano ndi chitukuko cha ukadaulo watsopano. Mkonzi adayambitsa mfundo, njira ndi zida zopera ufa za vacuum air atomization, ndikusanthula mitundu ndi ntchito za ufa wokonzedwa ndi vacuum air atomization.

Njira yopangira atomization ndi njira yokonzekera ufa momwe madzi othamanga (atomizing medium) amakhudza kapena kuswa madzi achitsulo kapena alloy kukhala madontho ang'onoang'ono, omwe kenako amasungunuka kukhala ufa wolimba. Tinthu ta ufa tomwe timakhala ndi atomu tomwe timakhala ndi kapangidwe ka mankhwala kofanana ndi alloy yosungunuka yomwe yaperekedwa, komanso chifukwa cha kuuma mwachangu kumakonza kapangidwe ka kristalo ndikuchotsa kugawanika kwa macrosegregation kwa gawo lachiwiri. Njira yogwiritsira ntchito atomization ndi madzi kapena ultrasound, yomwe imatchedwa water atomization ndi gasi atomization moyenerera. Ufa wachitsulo wokonzedwa ndi water atomization uli ndi zokolola zambiri komanso zotsika mtengo, ndipo liwiro lozizira limakhala lachangu, koma ufawo uli ndi mpweya wambiri komanso mawonekedwe osakhazikika, nthawi zambiri amakhala ndi ma flakes. Ufa wokonzedwa ndi ukadaulo wa ultrasonic atomization uli ndi tinthu tating'onoting'ono, sphericity yayikulu komanso mpweya wochepa, ndipo wakhala njira yayikulu yopangira ufa wachitsulo ndi alloy wozungulira wogwira ntchito kwambiri.

Ukadaulo wopukutira mpweya wa vacuum smelting wopanikizika kwambiri Ukadaulo wopukutira mpweya wa vacuum smelting wopanikizika kwambiri umaphatikiza ukadaulo wopukutira mpweya wa vacuum wokwera kwambiri, ukadaulo wopukutira mpweya wa kutentha kwambiri, ukadaulo wopukutira mpweya wa kuthamanga kwambiri komanso wachangu kwambiri, ndipo umapangidwa kuti ukwaniritse zosowa za chitukuko cha zitsulo za ufa, makamaka popanga ma alloys apamwamba okhala ndi zinthu zogwira ntchito za ufa. Ukadaulo wopukutira mpweya wa Ultrasonic / Gas ndi ukadaulo watsopano wolimbitsa mwachangu. Chifukwa cha kuzizira kwambiri, ufawo uli ndi mawonekedwe a kukonzedwa kwa tirigu, kapangidwe kofanana komanso kusungunuka kwakukulu kolimba.

Kuwonjezera pa zabwino zomwe zili pamwambapa, ufa wachitsulo wopangidwa ndi vacuum smelting atomization ya mpweya wopanikizika kwambiri uli ndi makhalidwe atatu awa: ufa wokha, mpweya wochepa; ufa wosalala wochuluka; mawonekedwe ozungulira. Zipangizo zopangidwa ndi ufa uwu zili ndi ubwino wambiri kuposa zipangizo wamba malinga ndi mphamvu zakuthupi ndi zamankhwala. Ufa wopangidwawo ndi monga ufa wa superalloy, ufa wa aloyi wothira kutentha, ufa wa aloyi wamkuwa ndi ufa wa chitsulo chosapanga dzimbiri.

1 Njira yopangira ufa pogwiritsa ntchito atomization ya mpweya wa vacuum ndi zida zake

1.1 Njira yopangira ufa wa atomization ya mpweya wa vacuum

Njira yopukutira mpweya wa vacuum ndi njira yatsopano yomwe yapangidwa m'makampani opanga ufa wachitsulo m'zaka zaposachedwa. Ili ndi ubwino wovuta kwambiri pakusungunuka kwa zinthu, kuzimitsa ufa wachitsulo mwachangu, komanso kudzipangira wekha kwambiri. Njira yeniyeni ndi yakuti alloy (chitsulo) ikasungunuka ndikukonzedwa mu uvuni wopangira induction, madzi osungunuka achitsulo amathiridwa mu thermal insulation slump, ndikulowa mu chubu chotsogolera ndi nozzle, ndipo madzi osungunuka amasungunuka ndi mpweya wothamanga kwambiri. Ufa wachitsulo wa atomu umauma ndikukhazikika mu nsanja ya atomu, ndikugwera mu thanki yosonkhanitsira ufa.

Zipangizo zoyeretsera mpweya, atomizing ultrasonic ndi madzi achitsulo ndi zinthu zitatu zofunika kwambiri pa njira yoyeretsera mpweya. Mu zipangizo zoyeretsera mpweya, atomizing ultrasonic yomwe yalowetsedwa imafulumizitsa ndikugwirizana ndi madzi achitsulo omwe alowetsedwa kuti apange malo oyeretsera mpweya. Mu malo oyeretsera mpweya, madzi achitsulo osungunuka amasweka, kuzizira ndi kuuma, motero amapeza ufa wokhala ndi makhalidwe enaake. Magawo a zida zoyeretsera mpweya amaphatikizapo kapangidwe ka nozzle, kapangidwe ka catheter, malo a catheter, ndi zina zotero, mpweya woyeretsera mpweya ndi magawo ake a njira zimaphatikizapo makhalidwe a ultrasonic, kuthamanga kwa mpweya, liwiro la mpweya, ndi zina zotero, ndi madzi achitsulo ndipo magawo ake a njira amaphatikizapo makhalidwe a madzi achitsulo, kutentha kwambiri, kukula kwa madzi, ndi zina zotero. Ultrasonic atomization imakwaniritsa cholinga chosintha kukula kwa tinthu ta ufa, kugawa kwa tinthu tating'onoting'ono ndi kapangidwe ka microstructure mwa kusintha magawo osiyanasiyana ndi kugwirizana kwawo.

1.2 Zida zopukutira mpweya wa vacuum

Zipangizo zopukusira za vacuum zomwe zimagwiritsidwa ntchito panopa zimaphatikizapo zida zakunja ndi zida zapakhomo. Zipangizo zomwe zimapangidwa kunja zimakhala ndi kukhazikika kwakukulu komanso kulondola kwambiri, koma mtengo wa zidazo ndi wokwera, ndipo mtengo wokonza ndi kukonza ndi wokwera. Mtengo wa zida zapakhomo ndi wotsika, mtengo wokonza ndi wotsika, ndipo kukonza ndikosavuta. Komabe, opanga zida zapakhomo nthawi zambiri sadziwa bwino ukadaulo wofunikira wa zida monga ma nozzles a atomizing ndi njira zopukusira. Pakadali pano, mabungwe ofufuza akunja oyenerera ndi makampani opanga zinthu amasunga ukadaulowu mwachinsinsi, ndipo magawo enieni komanso otsogola a njira sizingapezeke kuchokera m'mabuku ndi ma patent oyenera. Izi zimapangitsa kuti ufa wabwino kwambiri ukhale wotsika kwambiri kuti ukhale wotsika mtengo, chomwe ndi chifukwa chachikulu chomwe dziko langa silinathe kupanga ufa wabwino kwambiri ngakhale kuti pali mayunitsi ambiri opanga ufa wa aerosol ndi kafukufuku wasayansi.

Kapangidwe ka chipangizo choyeretsera atomization cha ultrasonic kamakhala ndi magawo otsatirawa: ng'anjo yosungunuka yapakatikati, ng'anjo yogwirira, dongosolo la atomization, thanki ya atomization, dongosolo losonkhanitsira fumbi, dongosolo loperekera ma ultrasound, dongosolo loziziritsira madzi, dongosolo lowongolera, ndi zina zotero.

Pakadali pano, kafukufuku wosiyanasiyana wokhudza kupumira mpweya amayang'ana kwambiri mbali ziwiri. Kumbali imodzi, magawo a kapangidwe ka nozzle ndi makhalidwe a kayendedwe ka jet akuphunziridwa. Cholinga chake ndikupeza ubale pakati pa munda wa mpweya ndi kapangidwe ka nozzle, kuti ultrasound ifike pa liwiro pa nozzle outlet pomwe kuchuluka kwa kuyenda kwa ultrasound kuli kochepa, ndipo imapereka maziko ophunzirira kapangidwe ndi kukonza nozzle. Kumbali ina, ubale pakati pa magawo a njira ya atomization ndi mawonekedwe a ufa unaphunziridwa. Cholinga chake ndi kuphunzira momwe magawo a njira ya atomization amakhudzira makhalidwe a ufa ndi magwiridwe antchito a atomization pamaziko apadera a nozzle kuti akonze bwino ndikuwongolera kupanga ufa. Mwachidule, kukonza kupanga ufa wabwino ndikuchepetsa kugwiritsa ntchito mpweya kumatsogolera njira yopangira ukadaulo wa atomization wa ultrasonic.

1.2.1 Mitundu yosiyanasiyana ya nozzles ya atomization ya ultrasonic

Mpweya wopangira atomiki umawonjezera liwiro ndi mphamvu kudzera mu nozzle, motero umaswa bwino chitsulo chamadzimadzi ndikukonza ufa womwe ukukwaniritsa zofunikira. Nozzle imalamulira kayendedwe ndi kayendedwe ka mpweya wa atomiki, ndipo imagwira ntchito yofunika kwambiri pamlingo wa atomiki bwino komanso kukhazikika kwa njira yopangira atomiki, ndipo ndi ukadaulo wofunikira wa atomization wa ultrasonic. Mu njira yoyambirira yopangira atomiki ya mpweya, kapangidwe ka nozzle ka free-fall kamagwiritsidwa ntchito nthawi zambiri. Nozzle iyi ndi yosavuta kupanga, si yosavuta kutsekeka, ndipo njira yowongolera ndi yosavuta, koma mphamvu yake yopangira atomiki si yayikulu, ndipo ndi yoyenera kupanga ufa wokhala ndi tinthu tating'onoting'ono ta 50-300 μm. Pofuna kukonza mphamvu ya atomiki, nozzle zoletsa kapena nozzle zolumikizana bwino za atomiki zidapangidwa pambuyo pake. Nozzle yolimba kapena yoletsa imafupikitsa mtunda wouluka wa mpweya ndikuchepetsa kutayika kwa mphamvu ya kinetic mu njira yoyendetsera mpweya, motero imawonjezera liwiro ndi kuchuluka kwa mpweya womwe umagwirizana ndi chitsulo, ndikuwonjezera phindu la ufa wabwino.

1.2.1.1 Mphuno Yozungulira Yozungulira

Ma ultrasound amphamvu kwambiri amalowa mu nozzle mozungulira. Kenako amatulutsidwa mwachangu kwambiri kuti apange vortex
