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。
烘干機筒體(ti)部分(fen)(fen)由(you)三(san)個同軸水平放置的(de)(de)(de)內(nei)、中、外(wai)筒套疊組成，這就(jiu)使筒體(ti)的(de)(de)(de)截面(mian)(mian)得到充分(fen)(fen)的(de)(de)(de)利用(yong)。其筒體(ti)外(wai)形總長度約為(wei)與(yu)之相當的(de)(de)(de)單筒的(de)(de)(de)30-35%。從(cong)而大幅度地減少占地面(mian)(mian)積(ji)和廠(chang)房建筑(zhu)面(mian)(mian)積(ji)。
該機的支承(cheng)裝置，是在(zai)外筒(tong)上輪帶與托(tuo)輪支承(cheng)，由電機直接(jie)帶動托(tuo)輪。通過托(tuo)輪與輪帶摩擦，使筒(tong)體轉(zhuan)動。該機總體結構緊湊(cou)、合理、簡單，為便于磨損件的檢修更換，在(zai)中(zhong)間(jian)設計(ji)成軸(zhou)向剖(pou)分式，用螺栓固(gu)定(ding)連接(jie)。
工作原理
物(wu)(wu)料由供料裝置進(jin)(jin)(jin)入(ru)回(hui)轉滾(gun)(gun)筒(tong)(tong)的(de)(de)內(nei)層(ceng)(ceng)(ceng)(ceng),實(shi)現(xian)(xian)順(shun)流(liu)(liu)烘干(gan),物(wu)(wu)料在(zai)內(nei)層(ceng)(ceng)(ceng)(ceng)的(de)(de)抄板下不(bu)斷(duan)抄起、散(san)落呈螺(luo)旋行(xing)進(jin)(jin)(jin)式(shi)實(shi)現(xian)(xian)熱交換，物(wu)(wu)料移動(dong)至內(nei)層(ceng)(ceng)(ceng)(ceng)的(de)(de)另一端(duan)進(jin)(jin)(jin)入(ru)中(zhong)層(ceng)(ceng)(ceng)(ceng)，進(jin)(jin)(jin)行(xing)逆流(liu)(liu)烘干(gan)，物(wu)(wu)料在(zai)中(zhong)層(ceng)(ceng)(ceng)(ceng)不(bu)斷(duan)地被反復(fu)揚進(jin)(jin)(jin)，呈進(jin)(jin)(jin)兩步(bu)(bu)退一步(bu)(bu)的(de)(de)行(xing)進(jin)(jin)(jin)方式(shi)，物(wu)(wu)料在(zai)中(zhong)層(ceng)(ceng)(ceng)(ceng)既充(chong)分吸(xi)收內(nei)層(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)(tong)散(san)發的(de)(de)熱量，又吸(xi)收中(zhong)層(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)(tong)的(de)(de)熱量，同時(shi)又延長(chang)了(le)干(gan)燥(zao)時(shi)間，物(wu)(wu)料在(zai)此達到(dao)干(gan)燥(zao)狀(zhuang)態。物(wu)(wu)料行(xing)至中(zhong)層(ceng)(ceng)(ceng)(ceng)另一端(duan)而落入(ru)外層(ceng)(ceng)(ceng)(ceng)，物(wu)(wu)料在(zai)外層(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)(tong)內(nei)呈矩(ju)形多回(hui)路(lu)方式(shi)行(xing)進(jin)(jin)(jin)，達到(dao)干(gan)燥(zao)效果的(de)(de)物(wu)(wu)料在(zai)熱風作用下快速行(xing)進(jin)(jin)(jin)排(pai)出滾(gun)(gun)筒(tong)(tong)，沒(mei)有達到(dao)干(gan)燥(zao)效果的(de)(de)濕物(wu)(wu)料因自重(zhong)而不(bu)能快速行(xing)進(jin)(jin)(jin)，物(wu)(wu)料在(zai)此矩(ju)形抄板內(nei)進(jin)(jin)(jin)行(xing)充(chong)分干(gan)燥(zao)，由此完成干(gan)燥(zao)目(mu)的(de)(de)。
