產品概況
回轉(zhuan)式三筒(tong)烘(hong)(hong)干(gan)機改進原(yuan)單筒(tong)烘(hong)(hong)干(gan)機內部(bu)結構，增加入機前濕料的預(yu)烘(hong)(hong)干(gan)和延長濕料在(zai)機內烘(hong)(hong)干(gan)時(shi)間，再加上密封、保溫以及(ji)合理(li)的配套措施，使烘(hong)(hong)干(gan)機生產能力與(yu)原(yuan)單筒(tong)式烘(hong)(hong)干(gan)機相比，提(ti)高48-80%，單位(wei)容積蒸發(fa)強度可達120-180kg/m3，標準煤(mei)耗僅為6-8kg/t。其技術先進、運行(xing)參數合理(li)，操作簡單可行(xing)，廣泛應用(yong)于各個行(xing)業的礦(kuang)渣(zha)、粘土(tu)、煤(mei)。
產品結構
三筒(tong)(tong)(tong)烘干機(ji)是(shi)通過對(dui)單筒(tong)(tong)(tong)烘干機(ji)的單筒(tong)(tong)(tong)體(ti)改為(wei)套(tao)疊在一起(qi)的三筒(tong)(tong)(tong)，以縮短(duan)烘干機(ji)體(ti)的外形(xing)尺寸(cun)。該機(ji)工作時(shi)，物料(liao)(liao)和熱氣(qi)流依(yi)次進入內至外筒(tong)(tong)(tong)體(ti)，在機(ji)體(ti)Z形(xing)往復折流后(hou)，充分利用熱能(neng)烘干物料(liao)(liao)后(hou)再卸出。
烘(hong)干機筒(tong)體部分(fen)由三個(ge)同(tong)軸(zhou)水平放置的(de)(de)內、中、外(wai)筒(tong)套疊組成，這就使筒(tong)體的(de)(de)截面(mian)得到充分(fen)的(de)(de)利用。其筒(tong)體外(wai)形(xing)總(zong)長度(du)約為(wei)與之相(xiang)當的(de)(de)單筒(tong)的(de)(de)30-35%。從而大幅度(du)地減少(shao)占地面(mian)積和廠房建筑面(mian)積。
該機(ji)的支承(cheng)裝置，是在外筒上輪(lun)(lun)(lun)帶(dai)與托(tuo)輪(lun)(lun)(lun)支承(cheng)，由(you)電機(ji)直接(jie)帶(dai)動托(tuo)輪(lun)(lun)(lun)。通(tong)過托(tuo)輪(lun)(lun)(lun)與輪(lun)(lun)(lun)帶(dai)摩擦(ca)，使(shi)筒體轉動。該機(ji)總體結構緊湊、合理、簡單，為便于磨(mo)損件的檢修更換，在中(zhong)間設(she)計成軸向剖分式，用螺栓固(gu)定連接(jie)。
工作原理
