產品概況
回轉式三(san)筒烘(hong)(hong)(hong)干機(ji)改進原單(dan)筒烘(hong)(hong)(hong)干機(ji)內部(bu)結(jie)構，增(zeng)加入(ru)機(ji)前濕(shi)料的(de)(de)預烘(hong)(hong)(hong)干和延長濕(shi)料在機(ji)內烘(hong)(hong)(hong)干時間，再加上密封、保(bao)溫以及合(he)理的(de)(de)配套(tao)措施，使烘(hong)(hong)(hong)干機(ji)生產能力與原單(dan)筒式烘(hong)(hong)(hong)干機(ji)相比，提高48-80%，單(dan)位容積蒸發(fa)強(qiang)度可達120-180kg/m3，標準煤耗僅為6-8kg/t。其技術(shu)先進、運行(xing)(xing)參數合(he)理，操作簡單(dan)可行(xing)(xing)，廣泛應用于(yu)各個行(xing)(xing)業的(de)(de)礦渣(zha)、粘土、煤。
產品(pin)結(jie)構
三筒(tong)烘(hong)干機(ji)(ji)是通過對單筒(tong)烘(hong)干機(ji)(ji)的(de)單筒(tong)體改為套疊在一起的(de)三筒(tong)，以(yi)縮短烘(hong)干機(ji)(ji)體的(de)外形尺寸。該機(ji)(ji)工作時，物料和熱氣流(liu)依次進入內至外筒(tong)體，在機(ji)(ji)體Z形往復折流(liu)后(hou)，充分(fen)利用熱能烘(hong)干物料后(hou)再卸出。
烘干機筒(tong)(tong)(tong)體(ti)(ti)部分(fen)由三個同軸水平放(fang)置的(de)內、中、外筒(tong)(tong)(tong)套疊組成，這(zhe)就使筒(tong)(tong)(tong)體(ti)(ti)的(de)截(jie)面得到充分(fen)的(de)利用(yong)。其筒(tong)(tong)(tong)體(ti)(ti)外形總(zong)長度約(yue)為與(yu)之相當(dang)的(de)單筒(tong)(tong)(tong)的(de)30-35%。從而(er)大幅(fu)度地減少占地面積和廠(chang)房建(jian)筑面積。
該機的支(zhi)承裝(zhuang)置，是在外筒(tong)上輪(lun)帶(dai)與(yu)托輪(lun)支(zhi)承，由電機直接帶(dai)動托輪(lun)。通過托輪(lun)與(yu)輪(lun)帶(dai)摩(mo)擦，使筒(tong)體(ti)轉動。該機總體(ti)結(jie)構(gou)緊湊(cou)、合理、簡單，為(wei)便于磨損件的檢修更(geng)換，在中間設計(ji)成軸向剖分式，用螺栓固定連接。
工作原理
