Dongo mchenga processing luso

Dongo mchenga processing luso
Ukadaulo waukadaulo wa mchenga wadongo ndi gawo lofunikira kwambiri pakuponya, kukhudza mwachindunji mtundu wa castings, mtengo wopanga, komanso kuteteza chilengedwe. Zotsatirazi zimapereka chidziwitso chokhazikika komanso chatsatanetsatane chaukadaulo uwu. Cholinga chachikulu
Mchenga wogwiritsidwa ntchito ndi wakale (womwe uli ndi dongo lolephera, ufa wa malasha, zonyansa, etc.) udzasinthidwa kuti ubwezeretse katundu wake, ndiyeno wothira mchenga watsopano, binder (dongo lambiri), ndi zowonjezera (ufa wa malasha, etc.) kukonzekera mtundu watsopano wa mchenga womwe umakwaniritsa zofunikira zoumba. Iyi ndi njira yobwezeretsanso.
Ndondomeko yoyendera (yotsekedwa-loop cycle)
Kupanga mchenga → Kuphwanya → Kulekanitsa maginito → Kujambula → (Kuziziritsa ndi -kusamalira mchenga wakale) → Kupanganso mchenga (gawo lofunika kwambiri) → Kuwonjeza mchenga watsopano/zowonjezera → Mchenga wosakanizidwa → Kuyezetsa ntchito mchenga → Kugwiritsa ntchito kuumba
Kufotokozera mwatsatanetsatane ndondomeko iliyonse
1. -gawo lamankhwala lisanachitike
Mchenga wakale usanalowe mkatikati mwa kubadwanso, uyenera kukonzekera.
Kupalasa mchenga ndi kuphwanya: Olekanitsa zotayira zoziziritsidwa pothira mu nkhungu zamchenga, ndipo mchenga waukulu umaphwanyidwa.
Kupatukana kwa maginito: Gwiritsani ntchito zida zolekanitsa maginito (maginito ng'oma, lamba) kuchotsa nyemba zachitsulo, misomali yachitsulo, m'mphepete mwa nyanja ndi ma burrs, ndi zina zotero.
Kuyang'ana: Chotsani core bones, wood blocks, sand blocks, etc. zomwe sizili-magnetic pogwiritsa ntchito vibrating screen kapena multi-angle screen.
2. Kuziziritsa ndi -kukonza mchenga wakale (gawo lofunika kwambiri)
Kutentha kwa mchenga wakale nthawi zambiri kumakhala 80-120 degrees . Mchenga wotentha kwambiri ungayambitse mavuto ambiri (kumamatira ku zipangizo, kutuluka kwa madzi, kukhudza ubwino wa mchenga wosakanikirana). Njira zoziziritsira:
Bedi lozirala lonjenjemera: Lodziwika kwambiri komanso lothandiza. Mpweya umawomberedwa mkati, ndipo mchenga umakhala wowira pa mbale yogwedezeka, uku uziziziritsa ndi kuchotsa fumbi.
Kawiri-disk cooler: Kuziziritsa pogwiritsa ntchito chipwirikiti ndi mpweya umagwiritsidwa ntchito, komanso kumakhala ndi ntchito-kusakaniza kale.
Makina ozizira ozizira: Kuziziritsa kudzera mukuzizira kwa mpweya ndi kutuluka kwa nkhungu yamadzi mu chogudubuza chozungulira.
3. Kusinthika kwa mchenga (pachiyambi)
Cholinga chake ndikuchotsa filimu yadongo yolephera (dongo lakufa) pamwamba pa njere za mchenga, zomwe ndi chinsinsi chobwezeretsanso katundu wa mchenga wa mchenga. Malinga ndi mphamvu ya regeneration, imagawidwa kukhala:
Choyamba-kusinthikanso (kusinthikanso): Chotsani pang'ono dongo lomwe lalephera chifukwa chakukangana. Zida wamba: Centrifugal rotor regeneration makina. Mchengawo umagwedezeka mwamphamvu ndikuwombana pakati pa rotor yozungulira ndi mbale ya liner, zomwe zimapangitsa kuti filimu yadongo iwonongeke. Ndiwoyenera kumafakitole ang'onoang'ono-osakayika kwambiri.
Kusinthika kwachiwiri-kwachiwiri (kusinthikanso kwamphamvu): Pamaziko a-kusinthikanso kwamlingo woyamba, onjezani kukhudza kapena kugaya.
Kusinthanso kwamphamvu kwa mpweya: Gwiritsani ntchito-kuthamanga kwambiri kwa mpweya kuti muthamangitse mchenga ndi kukhudza mbali yomwe mukufuna, zomwe zimapangitsa kuti mavulidwe awoneke bwino.
Kusinthika kwamphamvu kwamakina: Monga makina oyimirira kapena opingasa osinthika, kuphatikiza kukangana, kukhudzidwa ndikupera.
Wachiwiri-mchenga wopangidwanso ndi wapamwamba kwambiri ndipo ukhoza kugwiritsidwa ntchito popanga machubu a mchenga kapena ngati mchenga wa pamwamba.
4. Kulekanitsa mphepo ndi kuchotsa fumbi
Kulekanitsa mphepo: Mchenga wopangidwanso umalowa mu chipangizo cholekanitsa mphepo, pogwiritsa ntchito mpweya wotuluka kuti ulekanitse ufa wabwino (makamaka dongo lakufa ndi phulusa la ufa wa malasha) kuchokera ku mchenga woyenerera.
Kuchotsa fumbi: Dongosolo lonseli lili ndi zida zamphamvu zochotsa fumbi, kusonkhanitsa fumbi lopangidwa m'malo osiyanasiyana kuti zitsimikizire chitetezo cha chilengedwe komanso ukhondo wamisonkhano.
5. Mchenga wosakanizidwa ndi chosakaniza
Sakanizani mchenga wopangidwanso, mchenga watsopano wowonjezera (pafupifupi 5-15%), bentonite (dongo), ufa wa malasha (kapena zina zowonjezera carbonaceous), ndi madzi muyeso yeniyeni.
Zida zazikulu: Chosakaniza chozungulira (chogwira ntchito, yunifolomu).
Control core: Chida choyezera mchenga pa intaneti (monga kuchuluka kwa compactness, kuchuluka kwa chinyezi, chowongolera mphamvu), kusintha kuchuluka kwa madzi owonjezera ndi zina zowonjezera mu nthawi yeniyeni kutengera zotsatira za mayeso kuti muzitha kuzimitsa-loop automatic control.
6. Mchenga homogenization ndi kayendedwe
Mchenga wosakanizidwa woumba uyenera kusiyidwa kuti ukhale wa homogenize (kulola kuti chinyontho chilowemo mofanana) ndiyeno kutumizidwa kudzera mu lamba kapena makina oyendetsa mpweya kupita kumalo opangira.
Mtundu wa ndondomeko ndi kusankha
Malinga ndi masikelo osiyanasiyana opangira ndi kufunikira kwa mchenga, pali njira ziwiri zoyambira:
Centralized processing system: Yoyenera mizere yayikulu,{1}}yopanga zinthu imodzi (monga makina opangira magalimoto). Mchenga wakale wonse umakonzedwa pakati, ndi njira yaying'ono komanso makina apamwamba, komanso kasamalidwe kosavuta.
Dongosolo la mayunitsi: Ndilokwanira-zochitikira zosiyanasiyana, ting'onoting'ono-zochitikira (monga zida zamakina, makina olemera kwambiri). Mzere uliwonse wowumba uli ndi gawo lodziyimira pawokha la mchenga, lokhazikika komanso lopanda kusokoneza.
Zizindikiro zazikulu zaumisiri ndi kulamulira kwaubwino Zomwe zili ndi bentonite zogwira mtima komanso zowonjezera ufa wa malasha: Kuyesa nthawi zonse kumafunika (monga methylene blue titration njira), kuti atsogolere kuwonjezeredwa kwa bentonite yatsopano ndi ufa wa malasha.
Matope (omwe ali ndi ufa wabwino): Ayenera kulamulidwa pansi pa 12% -16%, monga momwe zilili zochulukirapo zidzakhudza kugwira ntchito kwa mchenga woumba.
Kutaya pakuyatsa: Kumawonetsa kuchuluka kwa zinthu zonse zoyaka mumchenga wowumba, ndipo kuyenera kuyendetsedwa pansi pa 3% -5%.
Kugawa kwa tinthu ting'onoting'ono: Sungani bata kuti mutsimikizire kuti 透气性和 pamwamba pa mchenga wowumba.
Zomwe zili m'madzi: Nthawi zambiri zimayendetsedwa pa 2.0% -3.5%, zomwe ndi "moyo" wa mchenga wowumba ndipo umayenera kuyendetsedwa bwino.
Mlingo wa kuphatikizika: Njira yabwino kwambiri yowongolera pa intaneti, yowonetsa kuuma-kunyowa ndi kukhuthala kwa mchenga, nthawi zambiri imayendetsedwa pa 35% -45%.
Chitukuko mchitidwe
Luntha ndi data yayikulu: Kugwiritsa ntchito masensa ndi umisiri wa intaneti wa Zinthu, kuyang'anira nthawi yeniyeni-kuyang'anira zochitika zonse, kudzera mu kusanthula kwakukulu kwa data kuneneratu momwe mchenga umawumba, kukwaniritsa kukonza bwino ndi kuwongolera moyenera.
Kugwiritsa ntchito bwino kwambiri komanso kupulumutsa mphamvu: Zipangizo zikukula-zambiri, zogwiritsa ntchito mphamvu zochepa, komanso sizitha kutha. Kugwiritsa ntchito kutentha kwa zinyalala kuchokera ku mchenga wotentha.
Kutetezedwa kwachilengedwe: Miyezo yosonkhanitsira ndi kuchiritsa fumbi ndi mpweya wotulutsa mpweya (monga ma VOC) ikukulirakulira.
Kusinthasintha: Mapangidwe ogwirizana komanso osinthika, ogwirizana ndi kufunikira kwa msika wamitundu ingapo ndi magulu ang'onoang'ono. Chidule
Ukadaulo waumisiri wa mchenga wadongo ndiumisiri wovuta wa makina omwe amaphatikiza zimango, zamadzimadzi, zowongolera zokha komanso sayansi yazinthu. Lingaliro lake lalikulu ndi "chuma chozungulira", kutanthauza kuchepetsa kugwiritsa ntchito mchenga kwatsopano komanso kutulutsa zinyalala zolimba pokonzanso bwino.
