產品結構

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(tong)(tong)(tong)體(ti)部(bu)分由(you)三(san)個同軸水平(ping)放置的(de)(de)內、中、外筒(tong)(tong)(tong)套疊組成，這就使筒(tong)(tong)(tong)體(ti)的(de)(de)截面得(de)到(dao)充分的(de)(de)利用。其筒(tong)(tong)(tong)體(ti)外形總長度(du)約為與之相(xiang)當(dang)的(de)(de)單筒(tong)(tong)(tong)的(de)(de)30-35%。從而大幅度(du)地(di)減(jian)少占地(di)面積(ji)和(he)廠房(fang)建筑面積(ji)。

該(gai)機(ji)的支(zhi)承裝(zhuang)置(zhi)，是在外筒(tong)上輪帶與托輪支(zhi)承，由電(dian)機(ji)直接(jie)帶動托輪。通過(guo)托輪與輪帶摩擦，使筒(tong)體轉動。該(gai)機(ji)總體結構(gou)緊(jin)湊(cou)、合理、簡單，為便于磨損件的檢修更換，在中間(jian)設(she)計成軸向剖分(fen)式(shi)，用螺(luo)栓固定連接(jie)。
