回轉式烘干機是一種工業設備，應用于肥料、冶金、化工、礦山、電力等行業。

工作原理

回轉烘干機是一種傾斜安裝的回轉式鋼筒體，斜度為3-6％，轉速為5-9r/min。

筒(tong)(tong)(tong)(tong)體(ti)(ti)(ti)上裝(zhuang)有輪帶(dai)和大齒(chi)圈。筒(tong)(tong)(tong)(tong)體(ti)(ti)(ti)依靠輪帶(dai)支撐在(zai)托(tuo)輪上。驅動(dong)裝(zhuang)置端(duan)的輪帶(dai)一側裝(zhuang)有擋(dang)輪，以限制筒(tong)(tong)(tong)(tong)體(ti)(ti)(ti)沿傾斜(xie)方向(xiang)的竄動(dong)。在(zai)烘(hong)(hong)干機(ji)(ji)設備底部溫度達(da)400℃-800℃狀態下，物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)由提升(sheng)機(ji)(ji)或(huo)者皮帶(dai)機(ji)(ji)從(cong)喂(wei)料(liao)(liao)(liao)(liao)口喂(wei)入(ru)烘(hong)(hong)干機(ji)(ji)筒(tong)(tong)(tong)(tong)體(ti)(ti)(ti)通過(guo)大齒(chi)圈在(zai)驅動(dong)裝(zhuang)置作(zuo)用下回轉，由于筒(tong)(tong)(tong)(tong)體(ti)(ti)(ti)具有一定的斜(xie)度且連續不(bu)斷地回轉，使得(de)物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)重力的作(zuo)用下從(cong)高(gao)端(duan)向(xiang)低端(duan)移(yi)(yi)動(dong)，在(zai)移(yi)(yi)動(dong)的過(guo)程中逐漸(jian)與熱(re)源產生的高(gao)溫氣(qi)體(ti)(ti)(ti)進行(xing)熱(re)交換。烘(hong)(hong)干后(hou)的物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)從(cong)低端(duan)卸(xie)出(chu)，物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)所(suo)含水份蒸發后(hou)被氣(qi)流帶(dai)走(zou)，物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)烘(hong)(hong)干機(ji)(ji)內停留時間約為13-20min，可(ke)根據(ju)根據(ju)物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)含水率進行(xing)不(bu)同設計。熱(re)氣(qi)體(ti)(ti)(ti)由熱(re)風爐生成，在(zai)烘(hong)(hong)干機(ji)(ji)內部物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)相接觸，通過(guo)熱(re)傳導，對流，輻射等多(duo)種方式(shi)將熱(re)量(liang)傳遞給物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)，從(cong)而使物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)溫度不(bu)斷升(sheng)高(gao)，水分(fen)不(bu)斷被蒸發，符合水分(fen)要(yao)(yao)求(qiu)的物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)從(cong)出(chu)料(liao)(liao)(liao)(liao)端(duan)出(chu)料(liao)(liao)(liao)(liao)罩下部出(chu)口卸(xie)料(liao)(liao)(liao)(liao),帶(dai)著水蒸汽(qi)的氣(qi)體(ti)(ti)(ti)經除塵器等環保設施(shi)處理后(hou)達(da)到(dao)環保要(yao)(yao)求(qiu)排放(fang)標(biao)的煙氣(qi)由引風機(ji)(ji)抽(chou)出(chu)經煙囪排空。

適用范圍

回(hui)轉式(shi)烘(hong)(hong)(hong)干機在(zai)傳統單筒回(hui)轉式(shi)烘(hong)(hong)(hong)干機結構的基礎(chu)上進行(xing)了大幅(fu)度(du)的突破和創新。從烘(hong)(hong)(hong)干機理上看，物(wu)料(liao)與熱氣流的交換更(geng)加充分(fen)、更(geng)為科(ke)學合(he)理。適應粘土(tu)、石(shi)(shi)膏、煤、礦(kuang)渣、煤矸(gan)石(shi)(shi)、混合(he)料(liao)、干混砂漿、黃砂、鐵粉等各種(zhong)原材料(liao)的烘(hong)(hong)(hong)干，也適用于磷肥(fei)、復合(he)肥(fei)生產中原料(liao)及冶金、化工(gong)等行(xing)業的各種(zhong)散狀物(wu)料(liao)的烘(hong)(hong)(hong)干。
