產品概況(kuang)
回轉式(shi)三筒(tong)(tong)烘(hong)干(gan)(gan)機改進(jin)原單(dan)筒(tong)(tong)烘(hong)干(gan)(gan)機內(nei)部結構，增(zeng)加入機前(qian)濕料(liao)的預烘(hong)干(gan)(gan)和延(yan)長(chang)濕料(liao)在(zai)機內(nei)烘(hong)干(gan)(gan)時間，再加上密封、保溫以(yi)及(ji)合(he)理(li)的配套措施(shi)，使烘(hong)干(gan)(gan)機生(sheng)產能力(li)與(yu)原單(dan)筒(tong)(tong)式(shi)烘(hong)干(gan)(gan)機相(xiang)比(bi)，提高48-80%，單(dan)位容(rong)積(ji)蒸發強度可達120-180kg/m3，標準(zhun)煤(mei)耗(hao)僅為6-8kg/t。其(qi)技術先進(jin)、運行(xing)參數(shu)合(he)理(li)，操(cao)作簡單(dan)可行(xing)，廣泛應用(yong)于(yu)各個(ge)行(xing)業的礦(kuang)渣、粘土、煤(mei)。
產品結構
三(san)筒(tong)(tong)烘干機(ji)是通(tong)過對單筒(tong)(tong)烘干機(ji)的(de)單筒(tong)(tong)體改(gai)為套(tao)疊在一起(qi)的(de)三(san)筒(tong)(tong)，以縮短(duan)烘干機(ji)體的(de)外(wai)形尺寸。該機(ji)工作時，物(wu)料(liao)和熱氣(qi)流依次進入內至外(wai)筒(tong)(tong)體，在機(ji)體Z形往(wang)復折流后(hou)，充分利用熱能烘干物(wu)料(liao)后(hou)再卸(xie)出。
烘干機筒(tong)(tong)體(ti)(ti)部分由三個同軸(zhou)水平(ping)放(fang)置的(de)內、中、外筒(tong)(tong)套疊組成，這就使筒(tong)(tong)體(ti)(ti)的(de)截面得到充分的(de)利(li)用(yong)。其筒(tong)(tong)體(ti)(ti)外形總長度(du)約為與(yu)之相當(dang)的(de)單筒(tong)(tong)的(de)30-35%。從而大(da)幅度(du)地(di)減少占地(di)面積(ji)(ji)和廠房建筑面積(ji)(ji)。
該機(ji)的支(zhi)承裝置(zhi)，是在外筒上輪(lun)帶與(yu)(yu)托輪(lun)支(zhi)承，由電機(ji)直(zhi)接帶動托輪(lun)。通(tong)過托輪(lun)與(yu)(yu)輪(lun)帶摩擦，使筒體(ti)轉動。該機(ji)總體(ti)結構緊湊、合理、簡單(dan)，為便于磨(mo)損件的檢修(xiu)更換，在中(zhong)間設計(ji)成軸向剖分式，用螺栓固定(ding)連接。
工作原(yuan)理
物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)由供料(liao)(liao)(liao)(liao)裝置(zhi)進(jin)(jin)(jin)入(ru)回(hui)轉滾(gun)筒(tong)的(de)(de)內層(ceng)(ceng)(ceng),實(shi)現順流烘干(gan)(gan)(gan),物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)內層(ceng)(ceng)(ceng)的(de)(de)抄板下不(bu)斷(duan)抄起、散落呈螺旋行(xing)(xing)進(jin)(jin)(jin)式實(shi)現熱(re)交換，物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)移動至內層(ceng)(ceng)(ceng)的(de)(de)另一(yi)端(duan)進(jin)(jin)(jin)入(ru)中(zhong)層(ceng)(ceng)(ceng)，進(jin)(jin)(jin)行(xing)(xing)逆流烘干(gan)(gan)(gan)，物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)中(zhong)層(ceng)(ceng)(ceng)不(bu)斷(duan)地(di)被(bei)反復揚(yang)進(jin)(jin)(jin)，呈進(jin)(jin)(jin)兩步退一(yi)步的(de)(de)行(xing)(xing)進(jin)(jin)(jin)方式，物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)中(zhong)層(ceng)(ceng)(ceng)既充分(fen)吸(xi)收內層(ceng)(ceng)(ceng)滾(gun)筒(tong)散發(fa)的(de)(de)熱(re)量，又吸(xi)收中(zhong)層(ceng)(ceng)(ceng)滾(gun)筒(tong)的(de)(de)熱(re)量，同(tong)時又延長了干(gan)(gan)(gan)燥(zao)時間，物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)此(ci)達到(dao)干(gan)(gan)(gan)燥(zao)狀態。物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)行(xing)(xing)至中(zhong)層(ceng)(ceng)(ceng)另一(yi)端(duan)而落入(ru)外層(ceng)(ceng)(ceng)，物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)外層(ceng)(ceng)(ceng)滾(gun)筒(tong)內呈矩形多回(hui)路方式行(xing)(xing)進(jin)(jin)(jin)，達到(dao)干(gan)(gan)(gan)燥(zao)效(xiao)果(guo)的(de)(de)物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)熱(re)風(feng)作用下快速行(xing)(xing)進(jin)(jin)(jin)排出(chu)滾(gun)筒(tong)，沒有(you)達到(dao)干(gan)(gan)(gan)燥(zao)效(xiao)果(guo)的(de)(de)濕物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)因自(zi)重而不(bu)能快速行(xing)(xing)進(jin)(jin)(jin)，物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)此(ci)矩形抄板內進(jin)(jin)(jin)行(xing)(xing)充分(fen)干(gan)(gan)(gan)燥(zao)，由此(ci)完(wan)成(cheng)干(gan)(gan)(gan)燥(zao)目(mu)的(de)(de)。
