產品結構
大型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)體部分由(you)三個同軸(zhou)水平放置的內、中、外筒(tong)套疊組成,這就使筒(tong)體的截面得到充分的利用。其筒(tong)體外形總長度(du)約為(wei)與之相當的單筒(tong)的30-35%。從而大幅度(du)地(di)減少占地(di)面積和廠房建(jian)筑(zhu)面積。
該機的支(zhi)承裝置,是在外筒上輪(lun)帶與托輪(lun)支(zhi)承,由(you)電機直(zhi)接帶動(dong)托輪(lun)。通過托輪(lun)與輪(lun)帶摩(mo)擦,使筒體轉動(dong)。該機總體結(jie)構緊(jin)湊、合理(li)、簡(jian)單,為便于磨損件(jian)的檢修更換,在中間設(she)計成軸(zhou)向剖分(fen)式,用螺(luo)栓固定連接。
