產品(pin)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(gou)
三筒(tong)式烘(hong)(hong)干機是通(tong)過對單筒(tong)烘(hong)(hong)干機的單筒(tong)體(ti)(ti)(ti)改為套疊在(zai)一起的三筒(tong),以縮短烘(hong)(hong)干機體(ti)(ti)(ti)的外(wai)形尺寸。該(gai)機工作時,物料和熱氣(qi)流(liu)依次進入內(nei)至外(wai)筒(tong)體(ti)(ti)(ti),在(zai)機體(ti)(ti)(ti)Z形往復折流(liu)后,充分利用熱能烘(hong)(hong)干物料后再卸(xie)出。
烘干機筒體(ti)部分(fen)由三個同軸水平(ping)放置的(de)(de)(de)內、中、外(wai)筒套疊(die)組成,這就使筒體(ti)的(de)(de)(de)截面得到充分(fen)的(de)(de)(de)利用。其筒體(ti)外(wai)形總長度約為與(yu)之(zhi)相當的(de)(de)(de)單筒的(de)(de)(de)30-35%。從而大幅度地減少(shao)占地面積和廠房建筑面積。
該機(ji)(ji)的(de)支(zhi)承裝置,是在外筒(tong)上輪(lun)(lun)帶(dai)與托(tuo)輪(lun)(lun)支(zhi)承,由電機(ji)(ji)直接帶(dai)動托(tuo)輪(lun)(lun)。通(tong)過托(tuo)輪(lun)(lun)與輪(lun)(lun)帶(dai)摩擦,使(shi)筒(tong)體轉動。該機(ji)(ji)總(zong)體結(jie)構(gou)緊湊、合理、簡(jian)單,為便于磨損件的(de)檢修更(geng)換,在中(zhong)間(jian)設計成軸向(xiang)剖分式,用螺栓固定連接。
工作原理(li)
