產品概況
回轉式三筒烘干機改進原單筒烘干機內部結構，增加入機前濕料的預烘干和延長濕料在機內烘干時間，再加上密封、保溫以及合理的配套措施，使烘干機生產能力與原單筒式烘干機相比，提高48-80%，單位容積蒸發強度可達120-180kg/m3，標準煤耗僅為6-8kg/t。其技術先進、運行參數合理，操作簡單可行，廣泛應用于各個行業的礦渣、粘土、煤。
產品結(jie)構
三(san)筒(tong)(tong)(tong)(tong)式烘干機(ji)是通過對單(dan)筒(tong)(tong)(tong)(tong)烘干機(ji)的單(dan)筒(tong)(tong)(tong)(tong)體改為(wei)套疊(die)在(zai)一起的三(san)筒(tong)(tong)(tong)(tong)，以縮短烘干機(ji)體的外形尺(chi)寸。該機(ji)工作時，物(wu)(wu)料和(he)熱(re)氣(qi)流依次進入內至外筒(tong)(tong)(tong)(tong)體，在(zai)機(ji)體Z形往復折流后，充分利用熱(re)能烘干物(wu)(wu)料后再卸出。
烘干(gan)機筒(tong)(tong)體部分由三個(ge)同(tong)軸水平放置的(de)(de)內、中、外筒(tong)(tong)套(tao)疊組(zu)成(cheng)，這就使筒(tong)(tong)體的(de)(de)截面得到充分的(de)(de)利(li)用(yong)。其筒(tong)(tong)體外形總長度(du)約為與之相當的(de)(de)單筒(tong)(tong)的(de)(de)30-35%。從而大幅度(du)地減少占地面積(ji)和(he)廠房(fang)建筑面積(ji)。
該機(ji)的支(zhi)承(cheng)裝置(zhi)，是在外(wai)筒(tong)上輪帶(dai)與(yu)托輪支(zhi)承(cheng)，由電機(ji)直(zhi)接(jie)帶(dai)動托輪。通(tong)過托輪與(yu)輪帶(dai)摩(mo)擦，使筒(tong)體轉動。該機(ji)總體結構緊湊、合(he)理、簡單，為便于磨損件的檢修更換，在中間(jian)設計成軸(zhou)向剖分式，用螺栓固定連接(jie)。
