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)(ti)部分(fen)由三個同軸(zhou)水平(ping)放置的內、中、外(wai)筒(tong)(tong)套疊組(zu)成,這就(jiu)使筒(tong)(tong)體(ti)(ti)的截面得到充分(fen)的利用。其筒(tong)(tong)體(ti)(ti)外(wai)形(xing)總長度約(yue)為與之相當(dang)的單筒(tong)(tong)的30-35%。從而(er)大幅(fu)度地減少(shao)占地面積和廠(chang)房建筑面積。
該(gai)機(ji)(ji)的支承裝置,是在(zai)外筒上輪帶與托(tuo)輪支承,由電(dian)機(ji)(ji)直接帶動(dong)托(tuo)輪。通過托(tuo)輪與輪帶摩擦,使(shi)筒體轉動(dong)。該(gai)機(ji)(ji)總體結(jie)構緊(jin)湊、合理、簡單(dan),為便于磨損件(jian)的檢修更換,在(zai)中間設(she)計成軸(zhou)向剖(pou)分(fen)式,用螺栓固定連(lian)接。
工作原理
物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)(liao)由供料(liao)(liao)(liao)(liao)(liao)(liao)裝(zhuang)置進(jin)(jin)入回轉滾(gun)(gun)筒的(de)內(nei)層(ceng)(ceng)(ceng),實(shi)現順流烘干,物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)(liao)在(zai)(zai)(zai)(zai)內(nei)層(ceng)(ceng)(ceng)的(de)抄板下不(bu)斷(duan)抄起、散落呈螺(luo)旋行(xing)(xing)進(jin)(jin)式實(shi)現熱交換,物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)(liao)移動至內(nei)層(ceng)(ceng)(ceng)的(de)另一(yi)端進(jin)(jin)入中(zhong)層(ceng)(ceng)(ceng),進(jin)(jin)行(xing)(xing)逆流烘干,物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)(liao)在(zai)(zai)(zai)(zai)中(zhong)層(ceng)(ceng)(ceng)不(bu)斷(duan)地被反復揚進(jin)(jin),呈進(jin)(jin)兩步退一(yi)步的(de)行(xing)(xing)進(jin)(jin)方式,物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)(liao)在(zai)(zai)(zai)(zai)中(zhong)層(ceng)(ceng)(ceng)既充分(fen)吸收(shou)內(nei)層(ceng)(ceng)(ceng)滾(gun)(gun)筒散發的(de)熱量,又(you)吸收(shou)中(zhong)層(ceng)(ceng)(ceng)滾(gun)(gun)筒的(de)熱量,同時又(you)延(yan)長了干燥(zao)時間,物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)(liao)在(zai)(zai)(zai)(zai)此(ci)達到(dao)干燥(zao)狀(zhuang)態(tai)。物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)(liao)行(xing)(xing)至中(zhong)層(ceng)(ceng)(ceng)另一(yi)端而落入外層(ceng)(ceng)(ceng),物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)(liao)在(zai)(zai)(zai)(zai)外層(ceng)(ceng)(ceng)滾(gun)(gun)筒內(nei)呈矩形多回路(lu)方式行(xing)(xing)進(jin)(jin),達到(dao)干燥(zao)效果的(de)物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)(liao)在(zai)(zai)(zai)(zai)熱風作用下快速行(xing)(xing)進(jin)(jin)排出滾(gun)(gun)筒,沒有達到(dao)干燥(zao)效果的(de)濕物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)(liao)因自(zi)重而不(bu)能快速行(xing)(xing)進(jin)(jin),物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)(liao)在(zai)(zai)(zai)(zai)此(ci)矩形抄板內(nei)進(jin)(jin)行(xing)(xing)充分(fen)干燥(zao),由此(ci)完成干燥(zao)目的(de)。
