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。
產品結構
三(san)筒(tong)(tong)式烘(hong)干(gan)機(ji)(ji)是通過對單筒(tong)(tong)烘(hong)干(gan)機(ji)(ji)的單筒(tong)(tong)體改為套(tao)疊在(zai)一起的三(san)筒(tong)(tong)，以縮(suo)短烘(hong)干(gan)機(ji)(ji)體的外(wai)形(xing)尺(chi)寸。該機(ji)(ji)工(gong)作時，物料和熱(re)氣流依次(ci)進入內至外(wai)筒(tong)(tong)體，在(zai)機(ji)(ji)體Z形(xing)往(wang)復折流后(hou)，充(chong)分利(li)用熱(re)能(neng)烘(hong)干(gan)物料后(hou)再卸(xie)出。
烘干(gan)機筒(tong)體部分由(you)三(san)個同軸水平放置的(de)內、中、外筒(tong)套疊組成，這就使筒(tong)體的(de)截面得到(dao)充分的(de)利用。其(qi)筒(tong)體外形總(zong)長度約(yue)為與之相當的(de)單(dan)筒(tong)的(de)30-35%。從而大幅度地減少占地面積和廠房(fang)建(jian)筑面積。
該機(ji)的支承裝置，是(shi)在外筒上輪帶與(yu)托(tuo)(tuo)輪支承，由電(dian)機(ji)直(zhi)接帶動托(tuo)(tuo)輪。通過(guo)托(tuo)(tuo)輪與(yu)輪帶摩(mo)擦，使筒體(ti)轉動。該機(ji)總體(ti)結構緊(jin)湊、合理、簡單，為便于磨(mo)損件的檢修更換，在中間設計(ji)成軸向(xiang)剖分式，用螺栓固定連接。
工作(zuo)原理
物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)(liao)由(you)供料(liao)(liao)(liao)(liao)(liao)(liao)裝置(zhi)進(jin)(jin)(jin)入(ru)回(hui)轉滾筒(tong)的內(nei)層(ceng),實現順(shun)流(liu)烘(hong)干,物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)(liao)在(zai)內(nei)層(ceng)的抄(chao)(chao)(chao)板下不斷(duan)抄(chao)(chao)(chao)起、散落(luo)呈螺(luo)旋行(xing)(xing)進(jin)(jin)(jin)式(shi)實現熱(re)(re)交換，物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)(liao)移動至內(nei)層(ceng)的另(ling)一端進(jin)(jin)(jin)入(ru)中(zhong)(zhong)層(ceng)，進(jin)(jin)(jin)行(xing)(xing)逆流(liu)烘(hong)干，物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)(liao)在(zai)中(zhong)(zhong)層(ceng)不斷(duan)地被反(fan)復揚進(jin)(jin)(jin)，呈進(jin)(jin)(jin)兩步退一步的行(xing)(xing)進(jin)(jin)(jin)方式(shi)，物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)(liao)在(zai)中(zhong)(zhong)層(ceng)既充分吸(xi)收(shou)內(nei)層(ceng)滾筒(tong)散發的熱(re)(re)量，又吸(xi)收(shou)中(zhong)(zhong)層(ceng)滾筒(tong)的熱(re)(re)量，同時(shi)又延長了(le)干燥(zao)時(shi)間，物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)(liao)在(zai)此(ci)達到干燥(zao)狀態。物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)(liao)行(xing)(xing)至中(zhong)(zhong)層(ceng)另(ling)一端而(er)落(luo)入(ru)外(wai)層(ceng)，物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)(liao)在(zai)外(wai)層(ceng)滾筒(tong)內(nei)呈矩形(xing)多回(hui)路方式(shi)行(xing)(xing)進(jin)(jin)(jin)，達到干燥(zao)效果的物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)(liao)在(zai)熱(re)(re)風作用下快速(su)行(xing)(xing)進(jin)(jin)(jin)排出(chu)滾筒(tong)，沒有(you)達到干燥(zao)效果的濕物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)(liao)因自重(zhong)而(er)不能(neng)快速(su)行(xing)(xing)進(jin)(jin)(jin)，物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)(liao)在(zai)此(ci)矩形(xing)抄(chao)(chao)(chao)板內(nei)進(jin)(jin)(jin)行(xing)(xing)充分干燥(zao)，由(you)此(ci)完成干燥(zao)目(mu)的。
