產品結構
大型三筒烘干機是通過對單筒烘干機的單筒體改為套疊在一起的三筒,以縮短烘干機體的外形尺寸。該機工作時,物料和熱氣流依次進入內至外筒體,在機體Z形往復折流后,充分利用熱能烘干物料后再卸出。
烘干(gan)機筒體(ti)部(bu)分(fen)由(you)三個(ge)同軸水平放(fang)置的(de)內、中(zhong)、外筒套疊組(zu)成(cheng),這就使筒體(ti)的(de)截面得到充分(fen)的(de)利(li)用。其(qi)筒體(ti)外形總(zong)長度約為與之相(xiang)當的(de)單筒的(de)30-35%。從而(er)大幅度地(di)減少占(zhan)地(di)面積和廠(chang)房建筑(zhu)面積。
該(gai)機(ji)(ji)的支承(cheng)裝(zhuang)置,是在外筒上輪帶與(yu)托輪支承(cheng),由電機(ji)(ji)直接帶動托輪。通(tong)過托輪與(yu)輪帶摩(mo)擦,使筒體轉動。該(gai)機(ji)(ji)總(zong)體結構緊湊(cou)、合理、簡單,為便于磨損(sun)件的檢修更換,在中間設計成軸(zhou)向剖分式,用螺栓(shuan)固定連(lian)接。
工作原理
物(wu)料(liao)(liao)由供(gong)料(liao)(liao)裝(zhuang)置進(jin)(jin)(jin)入(ru)回轉(zhuan)滾筒(tong)的內(nei)(nei)層(ceng)(ceng)(ceng)(ceng),實現(xian)(xian)順流(liu)(liu)烘干(gan),物(wu)料(liao)(liao)在(zai)(zai)(zai)(zai)(zai)內(nei)(nei)層(ceng)(ceng)(ceng)(ceng)的抄(chao)板(ban)下不(bu)(bu)(bu)斷抄(chao)起、散落呈(cheng)螺旋(xuan)行(xing)(xing)(xing)進(jin)(jin)(jin)式實現(xian)(xian)熱(re)(re)(re)交換,物(wu)料(liao)(liao)移動至內(nei)(nei)層(ceng)(ceng)(ceng)(ceng)的另一端進(jin)(jin)(jin)入(ru)中層(ceng)(ceng)(ceng)(ceng),進(jin)(jin)(jin)行(xing)(xing)(xing)逆流(liu)(liu)烘干(gan),物(wu)料(liao)(liao)在(zai)(zai)(zai)(zai)(zai)中層(ceng)(ceng)(ceng)(ceng)不(bu)(bu)(bu)斷地被(bei)反復揚進(jin)(jin)(jin),呈(cheng)進(jin)(jin)(jin)兩步退一步的行(xing)(xing)(xing)進(jin)(jin)(jin)方式,物(wu)料(liao)(liao)在(zai)(zai)(zai)(zai)(zai)中層(ceng)(ceng)(ceng)(ceng)既(ji)充分吸收內(nei)(nei)層(ceng)(ceng)(ceng)(ceng)滾筒(tong)散發的熱(re)(re)(re)量,又(you)(you)吸收中層(ceng)(ceng)(ceng)(ceng)滾筒(tong)的熱(re)(re)(re)量,同時又(you)(you)延(yan)長了干(gan)燥時間,物(wu)料(liao)(liao)在(zai)(zai)(zai)(zai)(zai)此達到(dao)(dao)干(gan)燥狀態。物(wu)料(liao)(liao)行(xing)(xing)(xing)至中層(ceng)(ceng)(ceng)(ceng)另一端而落入(ru)外層(ceng)(ceng)(ceng)(ceng),物(wu)料(liao)(liao)在(zai)(zai)(zai)(zai)(zai)外層(ceng)(ceng)(ceng)(ceng)滾筒(tong)內(nei)(nei)呈(cheng)矩形多(duo)回路(lu)方式行(xing)(xing)(xing)進(jin)(jin)(jin),達到(dao)(dao)干(gan)燥效果的物(wu)料(liao)(liao)在(zai)(zai)(zai)(zai)(zai)熱(re)(re)(re)風作用下快(kuai)速行(xing)(xing)(xing)進(jin)(jin)(jin)排出滾筒(tong),沒有達到(dao)(dao)干(gan)燥效果的濕物(wu)料(liao)(liao)因自重而不(bu)(bu)(bu)能快(kuai)速行(xing)(xing)(xing)進(jin)(jin)(jin),物(wu)料(liao)(liao)在(zai)(zai)(zai)(zai)(zai)此矩形抄(chao)板(ban)內(nei)(nei)進(jin)(jin)(jin)行(xing)(xing)(xing)充分干(gan)燥,由此完(wan)成干(gan)燥目的。
