產品結構
三筒式烘干機是通過對單筒烘干機的單筒體改為套疊在一起的三筒,以縮短烘干機體的外形尺寸。該機工作時,物料和熱氣流依次進入內至外筒體,在機體Z形往復折流后,充分利用熱能烘干物料后再卸出。
烘干機筒(tong)(tong)體(ti)部分由三個同軸(zhou)水平放(fang)置的內、中、外筒(tong)(tong)套疊組成,這就使(shi)筒(tong)(tong)體(ti)的截面(mian)(mian)得到充(chong)分的利(li)用。其(qi)筒(tong)(tong)體(ti)外形總長度約為(wei)與之相當的單筒(tong)(tong)的30-35%。從而大幅度地(di)(di)減少占地(di)(di)面(mian)(mian)積和廠房建筑面(mian)(mian)積。
該機(ji)(ji)的(de)支承(cheng)裝(zhuang)置(zhi),是(shi)在(zai)外(wai)筒上輪帶與托(tuo)輪支承(cheng),由電(dian)機(ji)(ji)直(zhi)接(jie)帶動托(tuo)輪。通過托(tuo)輪與輪帶摩擦(ca),使(shi)筒體轉動。該機(ji)(ji)總體結構緊湊(cou)、合(he)理、簡單(dan),為便于(yu)磨(mo)損件的(de)檢修更(geng)換,在(zai)中(zhong)間設計(ji)成軸向剖分式(shi),用螺栓固定連接(jie)。
工作原理
物(wu)料(liao)(liao)(liao)(liao)由(you)供料(liao)(liao)(liao)(liao)裝置進入(ru)回(hui)轉滾(gun)筒(tong)的(de)(de)(de)(de)內(nei)層(ceng)(ceng)(ceng)(ceng),實現(xian)(xian)順流烘(hong)干(gan)(gan),物(wu)料(liao)(liao)(liao)(liao)在(zai)內(nei)層(ceng)(ceng)(ceng)(ceng)的(de)(de)(de)(de)抄板下不(bu)斷抄起(qi)、散落(luo)呈螺旋(xuan)行(xing)進式(shi)實現(xian)(xian)熱交換(huan),物(wu)料(liao)(liao)(liao)(liao)移動至內(nei)層(ceng)(ceng)(ceng)(ceng)的(de)(de)(de)(de)另一端進入(ru)中層(ceng)(ceng)(ceng)(ceng),進行(xing)逆流烘(hong)干(gan)(gan),物(wu)料(liao)(liao)(liao)(liao)在(zai)中層(ceng)(ceng)(ceng)(ceng)不(bu)斷地被反復揚進,呈進兩步(bu)退一步(bu)的(de)(de)(de)(de)行(xing)進方式(shi),物(wu)料(liao)(liao)(liao)(liao)在(zai)中層(ceng)(ceng)(ceng)(ceng)既充分(fen)吸收內(nei)層(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)散發的(de)(de)(de)(de)熱量,又吸收中層(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)的(de)(de)(de)(de)熱量,同時又延長了干(gan)(gan)燥(zao)時間,物(wu)料(liao)(liao)(liao)(liao)在(zai)此(ci)達到(dao)干(gan)(gan)燥(zao)狀態。物(wu)料(liao)(liao)(liao)(liao)行(xing)至中層(ceng)(ceng)(ceng)(ceng)另一端而落(luo)入(ru)外層(ceng)(ceng)(ceng)(ceng),物(wu)料(liao)(liao)(liao)(liao)在(zai)外層(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)內(nei)呈矩形多回(hui)路(lu)方式(shi)行(xing)進,達到(dao)干(gan)(gan)燥(zao)效果(guo)的(de)(de)(de)(de)物(wu)料(liao)(liao)(liao)(liao)在(zai)熱風作用(yong)下快速行(xing)進排出滾(gun)筒(tong),沒有達到(dao)干(gan)(gan)燥(zao)效果(guo)的(de)(de)(de)(de)濕物(wu)料(liao)(liao)(liao)(liao)因自(zi)重而不(bu)能快速行(xing)進,物(wu)料(liao)(liao)(liao)(liao)在(zai)此(ci)矩形抄板內(nei)進行(xing)充分(fen)干(gan)(gan)燥(zao),由(you)此(ci)完成干(gan)(gan)燥(zao)目的(de)(de)(de)(de)。
