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)體部(bu)分(fen)由(you)三個同軸水平放置的內、中、外(wai)筒(tong)套(tao)疊組成(cheng),這(zhe)就使筒(tong)體的截面得到充分(fen)的利用。其(qi)筒(tong)體外(wai)形總長(chang)度(du)約為與之相當的單筒(tong)的30-35%。從而大(da)幅(fu)度(du)地減少占地面積和廠房建筑面積。
該(gai)(gai)機的(de)支(zhi)(zhi)承裝(zhuang)置,是在外筒上(shang)輪(lun)帶(dai)(dai)(dai)與托輪(lun)支(zhi)(zhi)承,由電機直接(jie)帶(dai)(dai)(dai)動(dong)托輪(lun)。通過(guo)托輪(lun)與輪(lun)帶(dai)(dai)(dai)摩擦,使筒體轉動(dong)。該(gai)(gai)機總(zong)體結(jie)構緊湊(cou)、合理、簡單,為(wei)便(bian)于磨損件的(de)檢修(xiu)更換(huan),在中間設計成軸向剖分式,用螺栓固定連接(jie)。
