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)部分由三個(ge)同軸(zhou)水平放置的內、中(zhong)、外(wai)(wai)筒(tong)(tong)(tong)套疊組成，這就使筒(tong)(tong)(tong)體(ti)的截面得到充分的利用。其筒(tong)(tong)(tong)體(ti)外(wai)(wai)形(xing)總長度約(yue)為與(yu)之相當的單(dan)筒(tong)(tong)(tong)的30-35%。從而大幅(fu)度地減少占(zhan)地面積(ji)和廠房(fang)建筑(zhu)面積(ji)。
該機的支(zhi)承裝置，是在外筒(tong)上(shang)輪(lun)帶與托輪(lun)支(zhi)承，由電機直(zhi)接(jie)帶動(dong)托輪(lun)。通過托輪(lun)與輪(lun)帶摩擦，使筒(tong)體轉動(dong)。該機總(zong)體結構緊湊(cou)、合理(li)、簡單，為便(bian)于(yu)磨損件的檢修更換，在中間設計成軸(zhou)向剖分式，用螺栓固(gu)定連接(jie)。
