產品概況
回(hui)轉(zhuan)式三筒(tong)(tong)烘(hong)(hong)干(gan)機(ji)改進原(yuan)單(dan)筒(tong)(tong)烘(hong)(hong)干(gan)機(ji)內(nei)部結構，增(zeng)加入機(ji)前濕(shi)料(liao)的預烘(hong)(hong)干(gan)和延長濕(shi)料(liao)在機(ji)內(nei)烘(hong)(hong)干(gan)時(shi)間，再加上密(mi)封(feng)、保溫以(yi)及合理(li)的配套(tao)措施(shi)，使烘(hong)(hong)干(gan)機(ji)生(sheng)產能力與原(yuan)單(dan)筒(tong)(tong)式烘(hong)(hong)干(gan)機(ji)相比，提高(gao)48-80%，單(dan)位(wei)容積(ji)蒸發強度可達120-180kg/m3，標準煤耗(hao)僅(jin)為6-8kg/t。其技術先進、運行參數合理(li)，操(cao)作簡(jian)單(dan)可行，廣泛應用于(yu)各個行業的礦渣、粘(zhan)土、煤。
產品結(jie)構
三(san)筒(tong)(tong)烘(hong)干(gan)(gan)機(ji)是通(tong)過對單筒(tong)(tong)烘(hong)干(gan)(gan)機(ji)的單筒(tong)(tong)體(ti)改為套疊在一起的三(san)筒(tong)(tong)，以(yi)縮短烘(hong)干(gan)(gan)機(ji)體(ti)的外形(xing)尺寸(cun)。該機(ji)工(gong)作時(shi)，物料(liao)和熱氣流依次(ci)進入內至外筒(tong)(tong)體(ti)，在機(ji)體(ti)Z形(xing)往(wang)復折流后，充分(fen)利用熱能烘(hong)干(gan)(gan)物料(liao)后再卸(xie)出(chu)。
烘干機筒(tong)(tong)(tong)體部分(fen)由(you)三個同軸(zhou)水平放置的(de)內、中(zhong)、外筒(tong)(tong)(tong)套疊組成，這就使筒(tong)(tong)(tong)體的(de)截面(mian)得到充分(fen)的(de)利用(yong)。其(qi)筒(tong)(tong)(tong)體外形總長度(du)約為與之相當(dang)的(de)單筒(tong)(tong)(tong)的(de)30-35%。從而大幅度(du)地減少占地面(mian)積(ji)和廠房建筑面(mian)積(ji)。
該(gai)機(ji)的(de)支承裝置，是在(zai)外筒上輪(lun)(lun)帶與托(tuo)輪(lun)(lun)支承，由電機(ji)直接(jie)帶動托(tuo)輪(lun)(lun)。通過托(tuo)輪(lun)(lun)與輪(lun)(lun)帶摩擦(ca)，使筒體轉動。該(gai)機(ji)總體結構緊湊(cou)、合理、簡單，為便于磨損件(jian)的(de)檢修更換，在(zai)中間設計(ji)成軸向(xiang)剖分式，用螺栓固(gu)定連接(jie)。
工作原理
物料(liao)由(you)供料(liao)裝置(zhi)進(jin)(jin)入(ru)(ru)(ru)回轉滾(gun)(gun)筒(tong)的(de)(de)內層(ceng)(ceng)(ceng)(ceng),實現(xian)順流(liu)(liu)烘干(gan),物料(liao)在內層(ceng)(ceng)(ceng)(ceng)的(de)(de)抄(chao)板下不(bu)斷(duan)抄(chao)起(qi)、散(san)(san)落呈螺旋行進(jin)(jin)式(shi)(shi)實現(xian)熱(re)交換(huan)，物料(liao)移動至(zhi)內層(ceng)(ceng)(ceng)(ceng)的(de)(de)另一(yi)端(duan)(duan)進(jin)(jin)入(ru)(ru)(ru)中(zhong)層(ceng)(ceng)(ceng)(ceng)，進(jin)(jin)行逆(ni)流(liu)(liu)烘干(gan)，物料(liao)在中(zhong)層(ceng)(ceng)(ceng)(ceng)不(bu)斷(duan)地被反復(fu)揚進(jin)(jin)，呈進(jin)(jin)兩步退一(yi)步的(de)(de)行進(jin)(jin)方式(shi)(shi)，物料(liao)在中(zhong)層(ceng)(ceng)(ceng)(ceng)既充(chong)分吸收內層(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)散(san)(san)發(fa)的(de)(de)熱(re)量(liang)，又吸收中(zhong)層(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)的(de)(de)熱(re)量(liang)，同時(shi)又延長(chang)了干(gan)燥(zao)時(shi)間(jian)，物料(liao)在此達到干(gan)燥(zao)狀態。物料(liao)行至(zhi)中(zhong)層(ceng)(ceng)(ceng)(ceng)另一(yi)端(duan)(duan)而(er)落入(ru)(ru)(ru)外層(ceng)(ceng)(ceng)(ceng)，物料(liao)在外層(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)內呈矩形多回路方式(shi)(shi)行進(jin)(jin)，達到干(gan)燥(zao)效果的(de)(de)物料(liao)在熱(re)風(feng)作用下快(kuai)速行進(jin)(jin)排(pai)出滾(gun)(gun)筒(tong)，沒有達到干(gan)燥(zao)效果的(de)(de)濕(shi)物料(liao)因自重而(er)不(bu)能快(kuai)速行進(jin)(jin)，物料(liao)在此矩形抄(chao)板內進(jin)(jin)行充(chong)分干(gan)燥(zao)，由(you)此完成干(gan)燥(zao)目的(de)(de)。
