產(chan)品概況(kuang)
回轉式三筒烘干機改進原單(dan)筒烘干機內(nei)部結構，增(zeng)加入機前濕(shi)料(liao)的預(yu)烘干和延長濕(shi)料(liao)在機內(nei)烘干時間，再加上密封(feng)、保溫以(yi)及合(he)理(li)的配套措施(shi)，使(shi)烘干機生(sheng)產能力與原單(dan)筒式烘干機相比，提高(gao)48-80%，單(dan)位(wei)容積蒸發強(qiang)度可(ke)(ke)達120-180kg/m3，標準煤耗僅(jin)為6-8kg/t。其技術先(xian)進、運(yun)行參數合(he)理(li)，操作(zuo)簡(jian)單(dan)可(ke)(ke)行，廣(guang)泛(fan)應用(yong)于各個行業的礦渣、粘土、煤。
產品結構
三(san)筒(tong)烘(hong)干(gan)機是通過(guo)對(dui)單(dan)筒(tong)烘(hong)干(gan)機的(de)單(dan)筒(tong)體(ti)改為套疊在(zai)一起的(de)三(san)筒(tong)，以縮(suo)短烘(hong)干(gan)機體(ti)的(de)外(wai)形(xing)尺寸。該機工(gong)作時，物(wu)料和熱氣流(liu)依次進(jin)入(ru)內至外(wai)筒(tong)體(ti)，在(zai)機體(ti)Z形(xing)往復(fu)折流(liu)后，充(chong)分利用熱能烘(hong)干(gan)物(wu)料后再(zai)卸出。
烘(hong)干機筒(tong)體部分由(you)三個同軸(zhou)水平放(fang)置的(de)內、中、外筒(tong)套疊(die)組成，這就(jiu)使(shi)筒(tong)體的(de)截面(mian)得到(dao)充分的(de)利用(yong)。其筒(tong)體外形總長(chang)度約為與(yu)之相(xiang)當的(de)單筒(tong)的(de)30-35%。從而大幅度地減少占地面(mian)積(ji)和廠房建筑面(mian)積(ji)。
該機(ji)的支承裝(zhuang)置，是(shi)在(zai)外(wai)筒上輪(lun)帶(dai)與托輪(lun)支承，由(you)電機(ji)直(zhi)接(jie)帶(dai)動托輪(lun)。通(tong)過托輪(lun)與輪(lun)帶(dai)摩擦，使(shi)筒體(ti)(ti)轉動。該機(ji)總(zong)體(ti)(ti)結構緊湊、合理、簡單，為便于磨損件的檢(jian)修更換，在(zai)中間設計成軸(zhou)向(xiang)剖分式(shi)，用螺栓(shuan)固定連接(jie)。
