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
三筒(tong)(tong)式烘(hong)(hong)干(gan)機(ji)(ji)(ji)是通過對單筒(tong)(tong)烘(hong)(hong)干(gan)機(ji)(ji)(ji)的單筒(tong)(tong)體改(gai)為套(tao)疊在一起的三筒(tong)(tong)，以縮短烘(hong)(hong)干(gan)機(ji)(ji)(ji)體的外形(xing)尺(chi)寸。該(gai)機(ji)(ji)(ji)工作(zuo)時(shi)，物(wu)料和熱氣流依次進入內至外筒(tong)(tong)體，在機(ji)(ji)(ji)體Z形(xing)往復折流后，充分利用熱能(neng)烘(hong)(hong)干(gan)物(wu)料后再(zai)卸出(chu)。
烘干機(ji)筒(tong)體(ti)部分由三個同軸水平放置的內、中、外筒(tong)套疊(die)組成，這就使筒(tong)體(ti)的截面得到充(chong)分的利用。其筒(tong)體(ti)外形總長度(du)約為與之相當(dang)的單(dan)筒(tong)的30-35%。從而大幅度(du)地減少占地面積和(he)廠房(fang)建(jian)筑面積。
該機(ji)的(de)支承(cheng)裝(zhuang)置，是在(zai)外(wai)筒(tong)上輪帶(dai)與托輪支承(cheng)，由電機(ji)直接帶(dai)動(dong)托輪。通過托輪與輪帶(dai)摩擦，使筒(tong)體轉動(dong)。該機(ji)總體結(jie)構緊湊、合理(li)、簡單，為(wei)便于磨損(sun)件的(de)檢修更(geng)換，在(zai)中間設計(ji)成(cheng)軸(zhou)向剖分(fen)式(shi)，用螺(luo)栓(shuan)固定連(lian)接。
