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(chan)品結構
三筒式烘干(gan)機(ji)是通過對單筒烘干(gan)機(ji)的(de)單筒體改為套疊(die)在一起的(de)三筒,以縮短烘干(gan)機(ji)體的(de)外形(xing)尺寸。該機(ji)工作時,物料和熱氣流(liu)依次進(jin)入內至外筒體,在機(ji)體Z形(xing)往復折流(liu)后,充分(fen)利用熱能(neng)烘干(gan)物料后再卸出(chu)。
烘干機筒(tong)體部分由三個(ge)同軸水平(ping)放置的內、中、外(wai)筒(tong)套疊組(zu)成,這就使筒(tong)體的截面(mian)(mian)得到充分的利用。其筒(tong)體外(wai)形(xing)總(zong)長(chang)度約為與(yu)之相當的單筒(tong)的30-35%。從而大幅(fu)度地減少占地面(mian)(mian)積(ji)和廠房建筑面(mian)(mian)積(ji)。
該機(ji)的支承裝置,是在外(wai)筒上輪帶與托輪支承,由電機(ji)直(zhi)接帶動托輪。通過托輪與輪帶摩(mo)擦,使筒體轉動。該機(ji)總體結構緊湊、合理、簡單,為便(bian)于磨損件的檢修更換,在中間設計成軸向剖分(fen)式(shi),用螺栓固定連接。
工作原理
