產品結構
三筒式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。
烘干機筒體部分(fen)由三(san)個同軸(zhou)水(shui)平(ping)放置的(de)內、中、外筒套疊組成(cheng),這就(jiu)使筒體的(de)截面(mian)得到(dao)充分(fen)的(de)利用。其(qi)筒體外形總長度約為與(yu)之(zhi)相當(dang)的(de)單筒的(de)30-35%。從而大幅度地減少占地面(mian)積(ji)和廠房建筑(zhu)面(mian)積(ji)。
該機(ji)的支(zhi)承(cheng)裝置,是在外筒(tong)上輪(lun)帶與(yu)托輪(lun)支(zhi)承(cheng),由電機(ji)直接(jie)帶動托輪(lun)。通過托輪(lun)與(yu)輪(lun)帶摩(mo)擦(ca),使筒(tong)體轉動。該機(ji)總體結構緊(jin)湊(cou)、合理、簡(jian)單,為(wei)便于(yu)磨(mo)損件(jian)的檢修更換,在中間設(she)計成軸向剖分式,用螺栓(shuan)固定連(lian)接(jie)。
