產品概況
回(hui)轉式(shi)三(san)筒(tong)烘干(gan)(gan)(gan)機(ji)改進(jin)原(yuan)單筒(tong)烘干(gan)(gan)(gan)機(ji)內(nei)部結(jie)構,增加(jia)入機(ji)前濕料的(de)(de)預(yu)烘干(gan)(gan)(gan)和延長(chang)濕料在機(ji)內(nei)烘干(gan)(gan)(gan)時間(jian),再加(jia)上(shang)密封、保溫以及(ji)合(he)理(li)的(de)(de)配套措施(shi),使(shi)烘干(gan)(gan)(gan)機(ji)生產能力(li)與原(yuan)單筒(tong)式(shi)烘干(gan)(gan)(gan)機(ji)相比,提高48-80%,單位容積(ji)蒸發強度可達120-180kg/m3,標準煤(mei)耗僅(jin)為6-8kg/t。其技術先(xian)進(jin)、運行參數合(he)理(li),操作簡單可行,廣泛(fan)應用于(yu)各個行業的(de)(de)礦渣、粘土、煤(mei)。
產品結構
三筒(tong)(tong)(tong)烘干機是(shi)通過對單筒(tong)(tong)(tong)烘干機的(de)單筒(tong)(tong)(tong)體(ti)改為套(tao)疊(die)在(zai)(zai)一起的(de)三筒(tong)(tong)(tong),以縮短(duan)烘干機體(ti)的(de)外形(xing)尺寸。該機工作時,物料和熱(re)氣流依次(ci)進入內至外筒(tong)(tong)(tong)體(ti),在(zai)(zai)機體(ti)Z形(xing)往復折流后(hou),充分(fen)利用熱(re)能烘干物料后(hou)再卸出(chu)。
烘干機筒(tong)體部分由三個同軸(zhou)水平放置的(de)內、中、外(wai)筒(tong)套疊(die)組成,這就使筒(tong)體的(de)截面(mian)得到充分的(de)利用。其筒(tong)體外(wai)形總(zong)長度(du)約為與之(zhi)相當的(de)單筒(tong)的(de)30-35%。從(cong)而大幅(fu)度(du)地減少占地面(mian)積(ji)和廠房(fang)建筑面(mian)積(ji)。
該機(ji)的支承裝置(zhi),是在(zai)外筒上輪(lun)帶與托輪(lun)支承,由電機(ji)直(zhi)接(jie)帶動托輪(lun)。通過托輪(lun)與輪(lun)帶摩擦,使筒體轉動。該機(ji)總(zong)體結構(gou)緊湊、合理(li)、簡(jian)單,為便于(yu)磨損件的檢(jian)修(xiu)更(geng)換(huan),在(zai)中間(jian)設計成軸向剖分(fen)式,用螺(luo)栓固定連接(jie)。
工作(zuo)原理
物(wu)料(liao)(liao)(liao)(liao)(liao)由供料(liao)(liao)(liao)(liao)(liao)裝(zhuang)置進(jin)(jin)入(ru)回轉(zhuan)滾(gun)筒(tong)(tong)的(de)內(nei)層(ceng)(ceng)(ceng)(ceng)(ceng),實(shi)現順流烘干(gan)(gan),物(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)內(nei)層(ceng)(ceng)(ceng)(ceng)(ceng)的(de)抄(chao)(chao)板下不斷抄(chao)(chao)起、散落呈螺旋行(xing)進(jin)(jin)式(shi)實(shi)現熱(re)(re)交換,物(wu)料(liao)(liao)(liao)(liao)(liao)移動至內(nei)層(ceng)(ceng)(ceng)(ceng)(ceng)的(de)另一端(duan)進(jin)(jin)入(ru)中(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng),進(jin)(jin)行(xing)逆流烘干(gan)(gan),物(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)中(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng)不斷地(di)被反復揚進(jin)(jin),呈進(jin)(jin)兩步退一步的(de)行(xing)進(jin)(jin)方(fang)式(shi),物(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)中(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng)既充分(fen)吸收(shou)內(nei)層(ceng)(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)(tong)散發的(de)熱(re)(re)量(liang),又吸收(shou)中(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)(tong)的(de)熱(re)(re)量(liang),同時又延(yan)長了干(gan)(gan)燥時間(jian),物(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)此達(da)到(dao)干(gan)(gan)燥狀態(tai)。物(wu)料(liao)(liao)(liao)(liao)(liao)行(xing)至中(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng)另一端(duan)而(er)落入(ru)外(wai)層(ceng)(ceng)(ceng)(ceng)(ceng),物(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)外(wai)層(ceng)(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)(tong)內(nei)呈矩(ju)形多回路(lu)方(fang)式(shi)行(xing)進(jin)(jin),達(da)到(dao)干(gan)(gan)燥效果的(de)物(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)熱(re)(re)風作用下快速行(xing)進(jin)(jin)排出滾(gun)筒(tong)(tong),沒有達(da)到(dao)干(gan)(gan)燥效果的(de)濕物(wu)料(liao)(liao)(liao)(liao)(liao)因自重(zhong)而(er)不能快速行(xing)進(jin)(jin),物(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)此矩(ju)形抄(chao)(chao)板內(nei)進(jin)(jin)行(xing)充分(fen)干(gan)(gan)燥,由此完成(cheng)干(gan)(gan)燥目的(de)。
