產(chan)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(gou)
三筒式烘(hong)(hong)干機(ji)是通過對單筒烘(hong)(hong)干機(ji)的單筒體(ti)(ti)改為套疊(die)在一起的三筒，以縮短烘(hong)(hong)干機(ji)體(ti)(ti)的外形(xing)尺(chi)寸。該機(ji)工作時，物(wu)料和熱氣流依次進(jin)入內(nei)至(zhi)外筒體(ti)(ti)，在機(ji)體(ti)(ti)Z形(xing)往復(fu)折流后(hou)，充分利用熱能烘(hong)(hong)干物(wu)料后(hou)再卸出。
烘干機筒(tong)體部分由三(san)個同軸水(shui)平放置的內、中(zhong)、外筒(tong)套疊(die)組(zu)成，這就(jiu)使筒(tong)體的截面得到充分的利用(yong)。其筒(tong)體外形總長(chang)度約為與之相(xiang)當(dang)的單筒(tong)的30-35%。從而大(da)幅度地減少占(zhan)地面積和(he)廠(chang)房建筑(zhu)面積。
該機的支(zhi)承(cheng)裝置，是在外筒上(shang)輪(lun)(lun)(lun)(lun)帶(dai)與托(tuo)輪(lun)(lun)(lun)(lun)支(zhi)承(cheng)，由電機直接帶(dai)動托(tuo)輪(lun)(lun)(lun)(lun)。通過托(tuo)輪(lun)(lun)(lun)(lun)與輪(lun)(lun)(lun)(lun)帶(dai)摩(mo)擦，使筒體(ti)(ti)轉動。該機總體(ti)(ti)結構緊湊、合理、簡單，為便于磨損件的檢修更(geng)換，在中間設計成(cheng)軸向剖分式，用(yong)螺栓固定連接。
