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。
烘干機筒體(ti)部分由三個同(tong)軸水(shui)平(ping)放置的(de)(de)(de)內、中、外(wai)筒套疊組成,這就使筒體(ti)的(de)(de)(de)截面得到(dao)充分的(de)(de)(de)利用。其筒體(ti)外(wai)形總長(chang)度(du)(du)約(yue)為與之相當的(de)(de)(de)單筒的(de)(de)(de)30-35%。從而大幅(fu)度(du)(du)地減少占地面積和廠(chang)房建筑面積。
該(gai)機(ji)的(de)支承裝(zhuang)置,是在外筒上輪(lun)帶與托輪(lun)支承,由電機(ji)直接(jie)帶動托輪(lun)。通過托輪(lun)與輪(lun)帶摩擦,使筒體轉動。該(gai)機(ji)總體結構緊湊、合理、簡(jian)單,為便于(yu)磨損件的(de)檢(jian)修更換(huan),在中(zhong)間設計成軸(zhou)向剖(pou)分式,用螺栓(shuan)固定連接(jie)。
