產品概況
回轉式三筒(tong)烘(hong)干(gan)(gan)機(ji)改(gai)進原單(dan)(dan)筒(tong)烘(hong)干(gan)(gan)機(ji)內部結構，增加入機(ji)前濕料(liao)(liao)的預烘(hong)干(gan)(gan)和延長濕料(liao)(liao)在機(ji)內烘(hong)干(gan)(gan)時間，再加上密封、保溫以(yi)及合理的配套措施，使烘(hong)干(gan)(gan)機(ji)生(sheng)產能力(li)與(yu)原單(dan)(dan)筒(tong)式烘(hong)干(gan)(gan)機(ji)相比，提高48-80%，單(dan)(dan)位容積蒸發(fa)強度(du)可(ke)達120-180kg/m3，標準煤耗僅為6-8kg/t。其技術先進、運行(xing)參數合理，操作簡單(dan)(dan)可(ke)行(xing)，廣泛應用于各個行(xing)業的礦渣、粘土、煤。
產品結(jie)構
三(san)筒(tong)(tong)烘(hong)干(gan)機是通過(guo)對(dui)單(dan)筒(tong)(tong)烘(hong)干(gan)機的(de)(de)單(dan)筒(tong)(tong)體(ti)(ti)改為套疊(die)在(zai)一起(qi)的(de)(de)三(san)筒(tong)(tong)，以縮短(duan)烘(hong)干(gan)機體(ti)(ti)的(de)(de)外形尺寸。該機工作(zuo)時(shi)，物料和熱(re)氣流(liu)依次(ci)進(jin)入內至外筒(tong)(tong)體(ti)(ti)，在(zai)機體(ti)(ti)Z形往復折流(liu)后，充分(fen)利用熱(re)能烘(hong)干(gan)物料后再卸出。
烘干機筒(tong)(tong)體部(bu)分由三個同軸水平放置的內、中、外(wai)筒(tong)(tong)套疊組成，這就使筒(tong)(tong)體的截面(mian)(mian)得到充分的利用(yong)。其筒(tong)(tong)體外(wai)形總長度約為(wei)與之(zhi)相當的單筒(tong)(tong)的30-35%。從而大(da)幅度地減少占地面(mian)(mian)積和廠房建(jian)筑面(mian)(mian)積。
該機(ji)的支(zhi)承裝置，是在(zai)外筒上輪(lun)帶(dai)與托輪(lun)支(zhi)承，由電(dian)機(ji)直接(jie)(jie)帶(dai)動托輪(lun)。通過托輪(lun)與輪(lun)帶(dai)摩擦(ca)，使(shi)筒體(ti)轉動。該機(ji)總(zong)體(ti)結構(gou)緊湊、合理、簡(jian)單，為便于磨損件的檢修更換(huan)，在(zai)中間設計(ji)成軸向剖分式(shi)，用(yong)螺栓固定連(lian)接(jie)(jie)。
工作原理
物(wu)(wu)料(liao)由(you)供料(liao)裝置進(jin)入回轉(zhuan)滾(gun)筒(tong)(tong)的(de)(de)(de)內(nei)層(ceng)(ceng)(ceng)(ceng),實現順流烘干(gan),物(wu)(wu)料(liao)在(zai)(zai)(zai)內(nei)層(ceng)(ceng)(ceng)(ceng)的(de)(de)(de)抄板(ban)下(xia)不(bu)斷(duan)抄起(qi)、散落呈螺旋行(xing)(xing)(xing)進(jin)式(shi)實現熱(re)交換，物(wu)(wu)料(liao)移動至(zhi)內(nei)層(ceng)(ceng)(ceng)(ceng)的(de)(de)(de)另一端進(jin)入中層(ceng)(ceng)(ceng)(ceng)，進(jin)行(xing)(xing)(xing)逆流烘干(gan)，物(wu)(wu)料(liao)在(zai)(zai)(zai)中層(ceng)(ceng)(ceng)(ceng)不(bu)斷(duan)地被反復揚進(jin)，呈進(jin)兩步(bu)退(tui)一步(bu)的(de)(de)(de)行(xing)(xing)(xing)進(jin)方式(shi)，物(wu)(wu)料(liao)在(zai)(zai)(zai)中層(ceng)(ceng)(ceng)(ceng)既充(chong)分吸收內(nei)層(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)(tong)散發的(de)(de)(de)熱(re)量，又吸收中層(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)(tong)的(de)(de)(de)熱(re)量，同時又延長了(le)干(gan)燥(zao)時間，物(wu)(wu)料(liao)在(zai)(zai)(zai)此達(da)(da)到(dao)干(gan)燥(zao)狀(zhuang)態。物(wu)(wu)料(liao)行(xing)(xing)(xing)至(zhi)中層(ceng)(ceng)(ceng)(ceng)另一端而落入外(wai)層(ceng)(ceng)(ceng)(ceng)，物(wu)(wu)料(liao)在(zai)(zai)(zai)外(wai)層(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)(tong)內(nei)呈矩形多回路方式(shi)行(xing)(xing)(xing)進(jin)，達(da)(da)到(dao)干(gan)燥(zao)效(xiao)果的(de)(de)(de)物(wu)(wu)料(liao)在(zai)(zai)(zai)熱(re)風作用(yong)下(xia)快(kuai)速行(xing)(xing)(xing)進(jin)排出滾(gun)筒(tong)(tong)，沒有達(da)(da)到(dao)干(gan)燥(zao)效(xiao)果的(de)(de)(de)濕物(wu)(wu)料(liao)因自重而不(bu)能(neng)快(kuai)速行(xing)(xing)(xing)進(jin)，物(wu)(wu)料(liao)在(zai)(zai)(zai)此矩形抄板(ban)內(nei)進(jin)行(xing)(xing)(xing)充(chong)分干(gan)燥(zao)，由(you)此完成干(gan)燥(zao)目的(de)(de)(de)。
