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)體(ti)部分由(you)三個同軸水(shui)平放(fang)置的(de)內、中(zhong)、外筒(tong)套疊(die)組成,這就使筒(tong)體(ti)的(de)截面(mian)得到(dao)充(chong)分的(de)利用。其(qi)筒(tong)體(ti)外形總長度(du)約(yue)為與之相(xiang)當的(de)單筒(tong)的(de)30-35%。從(cong)而大幅度(du)地減少占地面(mian)積和廠(chang)房建筑(zhu)面(mian)積。
該機的(de)支(zhi)承(cheng)裝(zhuang)置,是在(zai)外筒上輪帶(dai)與(yu)托輪支(zhi)承(cheng),由電機直接(jie)(jie)帶(dai)動(dong)托輪。通過托輪與(yu)輪帶(dai)摩擦,使筒體轉動(dong)。該機總體結構緊(jin)湊(cou)、合理、簡(jian)單,為便于磨損件的(de)檢(jian)修(xiu)更換,在(zai)中(zhong)間設計成軸向剖分式,用螺栓(shuan)固定連(lian)接(jie)(jie)。
工作原理
