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。
產品結構
三筒(tong)式烘干(gan)機是通過對(dui)單筒(tong)烘干(gan)機的單筒(tong)體改(gai)為套(tao)疊在一起的三筒(tong)，以縮(suo)短烘干(gan)機體的外形尺寸。該機工作時，物料(liao)和熱氣(qi)流依次進入內至外筒(tong)體，在機體Z形往復折流后(hou)，充分利用熱能烘干(gan)物料(liao)后(hou)再卸出。
烘干機筒(tong)(tong)(tong)體(ti)部分(fen)由三個(ge)同軸(zhou)水平放置的內、中(zhong)、外筒(tong)(tong)(tong)套疊組成，這就使(shi)筒(tong)(tong)(tong)體(ti)的截面得到充(chong)分(fen)的利用。其筒(tong)(tong)(tong)體(ti)外形總長度(du)約為與之相當的單筒(tong)(tong)(tong)的30-35%。從(cong)而大幅度(du)地減少占地面積和廠房建筑面積。
該機(ji)的支(zhi)(zhi)承(cheng)裝置，是在(zai)外筒上(shang)輪帶與(yu)托輪支(zhi)(zhi)承(cheng)，由(you)電機(ji)直(zhi)接帶動托輪。通過托輪與(yu)輪帶摩擦，使筒體轉動。該機(ji)總(zong)體結構緊湊、合理、簡單(dan)，為(wei)便(bian)于磨損件的檢修更換，在(zai)中間(jian)設計成軸向剖分式，用(yong)螺栓固定連接。
