產(chan)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)(ti)部分由三個(ge)同軸(zhou)水(shui)平放置的內、中、外(wai)(wai)筒(tong)套疊組成，這就使筒(tong)體(ti)(ti)的截面得(de)到充分的利用。其筒(tong)體(ti)(ti)外(wai)(wai)形總長度(du)約為與之相當的單筒(tong)的30-35%。從而大幅度(du)地減少占地面積和(he)廠房建(jian)筑面積。
該(gai)機(ji)的支承裝置，是在(zai)外(wai)筒(tong)上輪(lun)帶與托(tuo)輪(lun)支承，由電機(ji)直(zhi)接帶動托(tuo)輪(lun)。通過托(tuo)輪(lun)與輪(lun)帶摩擦，使(shi)筒(tong)體(ti)轉(zhuan)動。該(gai)機(ji)總體(ti)結構緊湊、合理、簡單，為(wei)便于磨損件的檢修(xiu)更換，在(zai)中間設計成軸向剖分式，用螺栓固定連接。
