產品(pin)概況(kuang)
回轉式三筒(tong)烘(hong)干(gan)(gan)機(ji)(ji)改進原(yuan)單(dan)筒(tong)烘(hong)干(gan)(gan)機(ji)(ji)內部結(jie)構，增加入機(ji)(ji)前濕(shi)料(liao)(liao)的(de)預烘(hong)干(gan)(gan)和延長濕(shi)料(liao)(liao)在機(ji)(ji)內烘(hong)干(gan)(gan)時間(jian)，再加上密封、保(bao)溫以及(ji)合理(li)的(de)配套措施，使烘(hong)干(gan)(gan)機(ji)(ji)生產(chan)能力與原(yuan)單(dan)筒(tong)式烘(hong)干(gan)(gan)機(ji)(ji)相(xiang)比，提高48-80%，單(dan)位容積蒸發強度可(ke)達120-180kg/m3，標準煤耗僅為6-8kg/t。其技(ji)術先進、運行參數合理(li)，操作(zuo)簡(jian)單(dan)可(ke)行，廣泛(fan)應用于各個行業(ye)的(de)礦(kuang)渣、粘(zhan)土、煤。
產品結構(gou)
三(san)筒(tong)(tong)烘(hong)干(gan)機是通過對單(dan)筒(tong)(tong)烘(hong)干(gan)機的(de)單(dan)筒(tong)(tong)體(ti)(ti)改為套(tao)疊在一起的(de)三(san)筒(tong)(tong)，以(yi)縮短(duan)烘(hong)干(gan)機體(ti)(ti)的(de)外(wai)形尺寸。該機工作(zuo)時，物料(liao)和熱氣流(liu)(liu)依(yi)次進入內至外(wai)筒(tong)(tong)體(ti)(ti)，在機體(ti)(ti)Z形往(wang)復折流(liu)(liu)后，充(chong)分利用(yong)熱能烘(hong)干(gan)物料(liao)后再卸出(chu)。
烘干機筒(tong)(tong)體部(bu)分(fen)由三個同軸水平放(fang)置的內、中、外筒(tong)(tong)套疊組成，這(zhe)就使筒(tong)(tong)體的截面(mian)得(de)到充分(fen)的利用。其筒(tong)(tong)體外形(xing)總長度(du)約為(wei)與(yu)之相當的單筒(tong)(tong)的30-35%。從而大幅度(du)地(di)減(jian)少占地(di)面(mian)積和廠房建筑面(mian)積。
該(gai)機的支承裝置，是在(zai)(zai)外筒上輪帶(dai)與托輪支承，由(you)電機直(zhi)接帶(dai)動(dong)托輪。通過托輪與輪帶(dai)摩擦，使筒體(ti)轉動(dong)。該(gai)機總體(ti)結(jie)構緊(jin)湊(cou)、合理、簡(jian)單，為(wei)便于磨損(sun)件(jian)的檢修(xiu)更換，在(zai)(zai)中(zhong)間設計成軸向剖分式，用螺(luo)栓固定連接。
工作原理
物(wu)料(liao)(liao)(liao)(liao)(liao)(liao)由(you)供料(liao)(liao)(liao)(liao)(liao)(liao)裝置進(jin)(jin)入(ru)回轉(zhuan)滾(gun)筒(tong)的內(nei)(nei)(nei)層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng),實現順流(liu)烘干(gan)(gan),物(wu)料(liao)(liao)(liao)(liao)(liao)(liao)在內(nei)(nei)(nei)層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)的抄(chao)板下不斷(duan)抄(chao)起、散落(luo)呈螺旋行(xing)進(jin)(jin)式實現熱交換，物(wu)料(liao)(liao)(liao)(liao)(liao)(liao)移動至內(nei)(nei)(nei)層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)的另一端進(jin)(jin)入(ru)中(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)，進(jin)(jin)行(xing)逆流(liu)烘干(gan)(gan)，物(wu)料(liao)(liao)(liao)(liao)(liao)(liao)在中(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)不斷(duan)地被反復揚進(jin)(jin)，呈進(jin)(jin)兩步退一步的行(xing)進(jin)(jin)方式，物(wu)料(liao)(liao)(liao)(liao)(liao)(liao)在中(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)既(ji)充(chong)分(fen)吸(xi)收內(nei)(nei)(nei)層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)散發的熱量(liang)，又吸(xi)收中(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)的熱量(liang)，同時又延(yan)長(chang)了干(gan)(gan)燥(zao)(zao)時間，物(wu)料(liao)(liao)(liao)(liao)(liao)(liao)在此達到(dao)(dao)干(gan)(gan)燥(zao)(zao)狀態。物(wu)料(liao)(liao)(liao)(liao)(liao)(liao)行(xing)至中(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)另一端而(er)落(luo)入(ru)外(wai)層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)，物(wu)料(liao)(liao)(liao)(liao)(liao)(liao)在外(wai)層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)內(nei)(nei)(nei)呈矩形(xing)多回路方式行(xing)進(jin)(jin)，達到(dao)(dao)干(gan)(gan)燥(zao)(zao)效(xiao)果的物(wu)料(liao)(liao)(liao)(liao)(liao)(liao)在熱風作(zuo)用(yong)下快速行(xing)進(jin)(jin)排出滾(gun)筒(tong)，沒有達到(dao)(dao)干(gan)(gan)燥(zao)(zao)效(xiao)果的濕物(wu)料(liao)(liao)(liao)(liao)(liao)(liao)因自重而(er)不能快速行(xing)進(jin)(jin)，物(wu)料(liao)(liao)(liao)(liao)(liao)(liao)在此矩形(xing)抄(chao)板內(nei)(nei)(nei)進(jin)(jin)行(xing)充(chong)分(fen)干(gan)(gan)燥(zao)(zao)，由(you)此完成干(gan)(gan)燥(zao)(zao)目的。
