Ephendula amaphutha angenhla womshini we-ring mold pellet, umbhali wenze umkhiqizo omusha we-Pellet ekwakhiweni kwesikhunta ekwakhekayo, futhi waklama uhlobo olusethiwe owakha isikhunta ngempilo ende yenkonzo, izindleko zokulungiswa okuphansi, kanye nokulungiswa okulula. Ngaleso sikhathi, le ndatshana yaqhuba ukuhlaziywa kwemishini kwesibumba esakhekayo ngesikhathi senqubo yayo yokusebenza.
1. I-Emplovement Design yesakhiwo sokubumba esakhekayo sokukhala kwe-Ring Mold Granulator
1.1 Isingeniso senqubo yokwakha ye-Extrusion:Umshini we-ring die pellet ungahlukaniswa ngezinhlobo ezimbili: mpo futhi zivundlile, kuya ngesimo sendandatho kufa; Ngokwefomu lokunyakaza, lingahlukaniswa ngezindlela ezimbili ezihlukile zokunyakaza: I-roller ecindezelayo esebenzayo enesikhunta endandatho esinqunyelwe kanye ne-roller ecindezelwe esebenzayo ngesikhunta endandatho ehunyushwa ngesikhunta endandatho ehunyushwa. Lo mklamo othuthukisiwe uhloselwe ikakhulukazi umshini wokubumba wezinhlayiyana nge-roller tress Ikakhulu iqukethe izingxenye ezimbili: Ukudlulisa imishini kanye ne-ring yokubumba yezinhlayiyana. Isikhunta sendandatho kanye nengcindezi ye-roller yizakhi ezimbili ezibalulekile zomshini we-pellet we-ring mold, enezimbobo eziningi zokubumba ezisatshalaliswa ezizungeze isikhunta sezindandatho, futhi i-roller yengcindezi ifakiwe ngaphakathi kokubumba kwendandatho. Ingcindezi yengcindezi ixhunyiwe kwisikhala sokuhambisa, futhi isikhunta sendandatho sifakwe kubakaki abahleliwe. Lapho i-spindle ijikeleza, iqhuba i-roller roller ukuze ijikeleze. Umgomo Wokusebenza: Okokuqala, indlela yokudlulisa ihambisa izinto ezichobozekile ze-biomass kusayizi othile wezinhlayiyana (3-5mm) egumbini lokucindezela. Ngemuva kwalokho, imoto ishayela shaft enkulu ukushayela umgibeli wengcindezi ukuze ujikeleze, futhi i-roller yengcindezi ihamba ngesivinini esingaguquki ukuze ihlakaze izinto ezibonakalayo phakathi kokucindezela kanye nokuphazamiseka ngezinto ezibonakalayo. Ngesikhathi senqubo yokuncipha kwezingxabano, i-cellulose kanye ne-hemishellulose ekuqukethwe okuhlanganisiwe nomunye. Ngasikhathi sinye, ukushisa okukhiqizwe ukungezwani okunciphisayo kuthambisa i-lignin ku-binder yemvelo, okwenza i-cellulose, i-hemishellulose, nezinye izingxenye ziboshwe ngokuqinile. Ngokugcwaliswa okuqhubekayo kwezinto ezibonakalayo ze-biomass, inani lezinto ezibonakalayo ezifakwe ekucindezelweni nasekungqubuzaneni ezigodini zokwakha zokwakha ziyaqhubeka. Ngasikhathi sinye, amandla okuncipha phakathi kwe-biomass ayaqhubeka anda, futhi ngokuqhubekayo ahlangana futhi akhanye emgodini wokubumba. Lapho ingcindezi ye-Extresion inkulu kune-Force Force, i-biomass ikhishwa ngokuqhubekayo kusuka ezimbozweni zokubumba ezizungeze isikhunta sezindandatho, yakha uphethiloli wokubumba we-biomass ngokubumba okungu-1g / cm3.
1.2 Ukugqokwa kokwakha isikhunta:Umphumela owodwa womshini wePellet mkhulu, une-degree ephezulu ye-automation kanye nokuvumelana okuqinile kwezinto ezisetshenziswayo. Ingasetshenziswa kabanzi ukucubungula izinto ezahlukahlukene ezisetshenziswayo ze-biomass raw, elungele ukukhiqizwa okuphezulu kwama-biomass abunwe abunye, nokuhlangabezana nezidingo zentuthuko ze-biomass izimboni ezibucayi ekwakhiweni kwezimboni zamafutha ngokuzayo. Ngakho-ke, umshini we-Cell Pellet usebenzisa kabanzi. Ngenxa yokuba khona okungaba khona kwamanani amancane esihlabathi nokunye okungeyona i-biomass ukungcola kwezinto ezisetshenzisiwe ze-biomass, kungenzeka kakhulu ukubangela ukugqokwa okubalulekile nokudabula okubunjiwe komshini we-pellet. Impilo yenkonzo yesikhunta sendandatho ibalwa ngokususelwa kwikhono lokukhiqiza. Njengamanje, impilo yenkonzo yokubumba kwendandatho eChina yi-100-1000t kuphela.
Ukwehluleka kokubumba kwendandatho kwenzeka ikakhulukazi kulesi sikhathi esine: ② Umthambeka wokondlayo womgodi we-die osungulayo wokubumba kwendandatho ugqokwa, okuholele ekunciphiseni kwenani lezinto ze-biomass, kanye ne-blockage elula yomuthi wokufa, okuholela ekwehlulekeni kwesikhunta sendandatho (Umdwebo 2); Ngemuva kwezinto zodonga ezingaphakathi futhi zinciphisa kakhulu inani lokukhipha (Umdwebo 3);
② Ngemuva kokugqoka komgodi wangaphakathi wesikhunta sendandatho, ukushuba udonga phakathi kwezimbumba ezisondelene naso luba mncane, okuholela ekunciphiseni amandla okubumba kwendandatho. Ukuqhekeka kuthambekele engxenyeni eyingozi kakhulu, futhi njengoba imifantu iyaqhubeka nokunweba, into ye-Ring of Ring Fold yenzeka. Isizathu esiyinhloko sokugqoka okulula kanye nokuphila okufushane kwenkonzo yokubumba kwendandatho kuyindlela engenangqondo yokwakheka okungenangqondo kwesikhunta sendandatho esakhelwayo (isikhunta sendandatho sihlanganiswe nemikhosi yokubumba eyakha). Ukwakheka okuhlanganisiwe kwalokhu okubili kuthambekele emiphumeleni enjalo: Kwesinye isikhathi lapho izimbobo ezimbalwa zokubumba zendandatho zidilizwa futhi azikwazi ukusebenza, nakho konke okubumba kwendandatho kudinga ukushintshwa, kepha kubangela ukushintshwa kwezindleko ezinkulu zomnotho futhi kwandise izindleko ezinkulu zezomnotho futhi kwandisa izindleko zezomnotho ezinkulu.
1.3 Idizayini yokuthuthukisa yokwakheka yokwakha isikhuntaUkuze unwebe impilo yenkonzo yokubumba kwendandatho yomshini wePellet, ukunciphisa ukugqokwa, ukunciphisa ukugqoka, futhi kunciphise izindleko zokulungiswa, kuyadingeka ukwenza umklamo omusha wokuthuthukiswa kokwenza ngcono ukwakheka kwesikhunta sendandatho. Isikhunta sokubumba esishumekiwe sasisetshenziswa ekwakhiweni, kanye nesakhiwo esithuthukisiwe seComnuction Chamber Chamber
Lo mklamo othuthukisiwe uhloselwe ikakhulukazi umshini wokubumba wezinhlayiya wezinhlayiya ngendabuko enendlela eshukumisayo ye-roller yengcindezi esebenzayo kanye nesikhunta esilungisiwe sendandatho. Isikhunta sendandatho esiphansi sihleliwe emzimbeni, futhi ama-roller amabili axhumene nomgwaqo omkhulu ngepuleti lokuxhuma. Isikhunta esesabekayo sishumeke esikhungweni sendandatho esingezansi (sisebenzisa amandla okuphazamisa), futhi isikhunta esiphezulu sendandatho sihleliwe ekubumbeni kwendandatho ephansi ngokusebenzisa ama-bolts futhi kuhlanganiswe kulokhu okwakha isikhunta. Ngasikhathi sinye, ukuze uvikele isikhunta esakhekayo kusuka ekuvuselelekeni ngenxa yokuphoqelela ngemuva kokuthi i-roller yengcindezi iyadlula futhi ihambisane ngokulandelana kwezindandatho, izikulufo ze-countersunk zisetshenziselwa ukulungiselela isikhunta sendandatho esingenhla ngokulandelana. Ukuze sinciphise ukumelana kokuqukethwe okufakwayo emgodini futhi kwenze kube lula ukwengeza umgodi wokubumba. I-angle ye-conical yomgodi wokudla kwalesi sikhunta eklanyelwe ukwakheka kungu-60 ° kuya ku-120 °.
Umklamo owenziwe ngcono wesakhiwo wokubumba owakhekayo unezici zomjikelezo ohlukahlukene kanye nempilo yenkonzo ende. Lapho umshini wezinhlayiyana usebenzela isikhathi esithile, ukulahleka kwezingxabano kubangela ukubambezeleka kokubumba kwakheka kwakhiwe kube mkhulu futhi kuqhume. Lapho isikhunta esigqokwa sisuswa futhi sinwetshwa, singasetshenziselwa ukukhiqizwa kwezinye ukucaciswa kokwenza izinhlayiya. Lokhu kungafinyelela ukusetshenziswa kabusha kwezikhunta bese ugcine izindleko zokugcina kanye nezindleko zokubuyiselwa.
Ukuze unwebe impilo yenkonzo ye-granulator futhi unciphise izindleko zokukhiqiza, i-roller yengcindezi yamukela insimbi ephezulu ye-carbon manganese ngokumelana okuhle, njenge-65mn. Ukubumba okwakhekayo kufanele kwenziwe ngensimbi ye-alloy carbulid noma i-chromium ephansi ye-chromium, efana ne-Cr, MN, TI, njll. Ngenxa yokuthuthuka kweRing Cons Ngakho-ke, i-carbon yensimbi ejwayelekile, efana nensimbi engu-45, ingasetshenziswa njengokuqukethwe kwegumbi lokucindezela. Uma kuqhathaniswa nokubumba okuhlanganisiwe kwendandatho kwendandatho, kunganciphisa ukusetshenziswa kwensimbi ebizayo, ngaleyo ndlela kwehlise izindleko zokukhiqiza.
