1, silinda yolumikizira
(1) Kapangidwe ka sipo yozungulira
Chophimba cha silinda chimapangidwa makamaka ndi makina otumizira, shaft yayikulu, chimango cha sieve, ukonde wa sikirini, chivundikiro chotsekedwa ndi chimango.
Kuti tinthu tating'onoting'ono tosiyanasiyana tipezeke nthawi imodzi, makulidwe osiyanasiyana a zotchingira amatha kuyikidwa muutali wonse wa sieve. Pakupanga graphitization, makulidwe awiri osiyana a zotchingira nthawi zambiri amayikidwa, kuti achepetse kukula kwa tinthu tating'onoting'ono ta zinthu zotchingira. Ndipo zipangizo zazikulu kuposa kukula kwakukulu kwa tinthu tating'onoting'ono ta zinthu zotchingira zitha kusefedwa, sieve ya dzenje laling'ono la sieve imayikidwa pafupi ndi malo olowera chakudya, ndipo chinsalu cha dzenje lalikulu la sieve chimayikidwa pafupi ndi potulukira madzi.
(2) Mfundo yogwirira ntchito ya silinda yozungulira
Mota imazungulira mzere wapakati wa sikirini kudzera mu chipangizo chochepetsera mphamvu, ndipo zinthuzo zimakwezedwa kufika pamlingo winawake mu silinda chifukwa cha mphamvu yokoka, kenako zimagubuduzika pansi ndi mphamvu yokoka, kotero kuti zinthuzo zimasefedwa pamene zikupendekeka pamwamba pa sikirini yopendekeka. Pang'onopang'ono kuchoka kumapeto kwa chakudya kupita kumapeto kwa kutulutsa, tinthu tating'onoting'ono timadutsa kudzera mu dzenje kulowa mu sikirini, ndipo tinthu tating'onoting'ono timasonkhanitsidwa kumapeto kwa sikirini yopendekeka.
Kuti zinthu zomwe zili mu silinda zisunthike mbali ina ya axial, ziyenera kuyikidwa mopingasa, ndipo ngodya pakati pa mzere ndi malo opingasa nthawi zambiri imakhala 4°–9°. Liwiro lozungulira la silinda nthawi zambiri limasankhidwa mkati mwa magawo otsatirawa.
(kusamutsa / mphindi)
Mzere wamkati wa mbiya R (mita).
Mphamvu yopangira sieve yozungulira ikhoza kuwerengedwa motere:
Mphamvu yopangira sefa ya Q-barrel (ton/ola); liwiro lozungulira sefa ya n-barrel (rev/min);
Kuchuluka kwa zinthu (ton / cubic meter) μ - kuchuluka kwa zinthu zotayirira, nthawi zambiri kumatenga 0.4-0.6;
R-bar inner radius (m) h – gawo la zinthu makulidwe apamwamba (m) α – ngodya yopendekera (madigiri) ya sieve yozungulira.
Chithunzi 3-5 Chithunzi chojambula cha silinda
2, chikepe cha ndowa
(1) kapangidwe ka chikepe cha ndowa
Chikepe chokwezera chidebe chimapangidwa ndi hopper, unyolo wotumizira (lamba), gawo lotumizira, gawo lapamwamba, chivundikiro chapakati, ndi gawo lapansi (mchira). Pakupanga, chikepe chokwezera chidebe chiyenera kudyetsedwa mofanana, ndipo chakudya sichiyenera kukhala chochuluka kuti gawo lapansi lisatsekedwe ndi zinthuzo. Chikepe chikagwira ntchito, zitseko zonse zowunikira ziyenera kutsekedwa. Ngati pali vuto panthawi yogwira ntchito, siyani kugwira ntchito nthawi yomweyo ndikuchotsa vuto. Ogwira ntchito ayenera kuyang'anira nthawi zonse mayendedwe a zigawo zonse za chikepe, yang'anani mabaluti olumikizira kulikonse ndikuzilimbitsa nthawi iliyonse. Chipangizo chotsekera cha spiral cha gawo lapansi chiyenera kusinthidwa kuti zitsimikizire kuti unyolo wa hopper (kapena lamba) uli ndi mphamvu yogwira ntchito bwino. Chikepecho chiyenera kuyatsidwa popanda katundu ndikuyimitsidwa zinthu zonse zitatulutsidwa.
(2) mphamvu yopangira chikepe cha ndowa
Kuchuluka kwa kupanga Q
Kumene voliyumu ya i0-hopper (makiyubiki mita); pitch ya a-hopper (m); liwiro la v-hopper (m/h);
Chinthu chodzaza φ nthawi zambiri chimatengedwa ngati 0.7; mphamvu yokoka ya γ-zinthu (ton/m3);
Κ - kuchuluka kwa zinthu zosafanana, tengani 1.2 ~ 1.6.
Chithunzi 3-6 Chithunzi chojambula cha elevator ya chidebe
Mphamvu yopangira sikirini ya Q-barrel (ton / ola); liwiro la sikirini ya n-barrel (rev / min);
Kuchuluka kwa zinthu (ton / cubic meter) μ - kuchuluka kwa zinthu zotayirira, nthawi zambiri kumatenga 0.4-0.6;
R-bar inner radius (m) h – gawo la zinthu makulidwe apamwamba (m) α – ngodya yopendekera (madigiri) ya sieve yozungulira.
Chithunzi 3-5 Chithunzi chojambula cha silinda
3, chonyamulira lamba
Mitundu ya ma conveyor a lamba imagawidwa m'ma conveyor okhazikika ndi osunthika. Conveyor ya lamba wokhazikika imatanthauza kuti conveyor ili pamalo okhazikika ndipo zinthu zomwe ziyenera kusamutsidwa zakhazikika. Gudumu la lamba lotsetsereka limayikidwa pansi pa conveyor ya lamba woyenda, ndipo conveyor ya lamba ikhoza kusunthidwa kudzera m'mabwalo pansi kuti ikwaniritse cholinga chotumizira zinthu m'malo osiyanasiyana. Conveyor iyenera kuwonjezeredwa ndi mafuta odzola munthawi yake, iyenera kuyambika popanda katundu, ndipo ikhoza kukwezedwa ndikuyendetsedwa mutatha kuthamanga popanda kupotoka kulikonse. Zapezeka kuti lamba litazimitsidwa, ndikofunikira kudziwa chifukwa cha kupotoka munthawi yake, kenako kusintha zinthuzo zitatsitsidwa pa lamba.
Chithunzi 3-7 Chithunzi chojambula cha chonyamulira lamba
Chingwe chamkati cha graphitization
Mbali ya pamwamba ya chingwe chamkati ndi yakuti ma electrode amalumikizidwa pamodzi mbali ya axial ndipo kupanikizika kwina kumayikidwa kuti zitsimikizire kuti zikugwirizana bwino. Chingwe chamkati sichifunikira chinthu cholimbana ndi magetsi, ndipo chinthucho chimapanga maziko a ng'anjo, kotero kuti chingwe chamkati chimakhala ndi kukana pang'ono kwa ng'anjo. Kuti chikhale ndi kukana kwakukulu kwa ng'anjo, komanso kuti chiwonjezere kutulutsa, ng'anjo yamkati iyenera kukhala yayitali mokwanira. Komabe, chifukwa cha zofooka za fakitale, ndipo tikufuna kutsimikizira kutalika kwa ng'anjo yamkati, ma ng'anjo ambiri ofanana ndi U adamangidwa. Magawo awiri a ng'anjo yamkati yokhala ndi mawonekedwe a U amatha kumangidwa kukhala thupi ndikulumikizidwa ndi bar yofewa yamkuwa yakunja. Itha kumangidwanso kukhala imodzi, yokhala ndi khoma la njerwa lopanda kanthu pakati. Ntchito ya khoma la njerwa lopanda kanthu pakati ndikuligawa m'magawo awiri a ng'anjo omwe amatetezedwa kuchokera kwa wina ndi mnzake. Ngati lamangidwa kukhala limodzi, ndiye kuti popanga, tiyenera kusamala ndi kukonza khoma la njerwa lopanda kanthu pakati ndi electrode yolumikizira yamkati. Khoma la njerwa lapakati lopanda chitoliro chabwino likapanda kutetezedwa bwino, kapena electrode yolumikizira yamkati ikasweka, izi zingayambitse ngozi yopanga, yomwe imachitika nthawi zambiri. Chochitika cha "ng'anjo yophulika". Mizere yooneka ngati U ya chingwe chamkati nthawi zambiri imapangidwa ndi njerwa zosagwira kutentha kapena konkire yosatentha. Mzere wogawanika wooneka ngati U umapangidwanso ndi mitembo yambiri yopangidwa ndi mbale zachitsulo kenako n’kulumikizidwa ndi chinthu chotetezera kutentha. Komabe, zatsimikiziridwa kuti mitembo yopangidwa ndi mbale yachitsulo imasokonekera mosavuta, kotero kuti zinthu zotetezera kutentha sizingalumikize bwino mitembo iwiriyo, ndipo ntchito yokonza ndi yayikulu.
Chithunzi 3-8 Chithunzi chojambula cha ng'anjo yamkati yokhala ndi khoma la njerwa lopanda kanthu pakati
Nkhaniyi ndi yongophunzira ndi kugawana, osati yogwiritsa ntchito bizinesi. Lumikizanani nafe ngati pali vuto.
