產品結構
三筒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)體部分(fen)(fen)由三個同軸(zhou)水平放置的(de)內、中、外筒(tong)套疊組成,這(zhe)就使筒(tong)體的(de)截面得(de)到充分(fen)(fen)的(de)利用(yong)。其筒(tong)體外形總長度約為與之相當的(de)單筒(tong)的(de)30-35%。從而大幅(fu)度地(di)減少占地(di)面積和(he)廠房建筑面積。
該機(ji)的(de)支承(cheng)裝(zhuang)置,是(shi)在外筒(tong)上輪(lun)帶(dai)(dai)(dai)與托(tuo)輪(lun)支承(cheng),由(you)電機(ji)直接帶(dai)(dai)(dai)動(dong)托(tuo)輪(lun)。通過托(tuo)輪(lun)與輪(lun)帶(dai)(dai)(dai)摩擦,使筒(tong)體轉動(dong)。該機(ji)總體結(jie)構緊湊、合理、簡單,為(wei)便于磨損件的(de)檢(jian)修更(geng)換,在中(zhong)間設計成軸向剖分式,用螺栓(shuan)固定連(lian)接。
工作(zuo)原理
物(wu)(wu)料(liao)(liao)由(you)供(gong)料(liao)(liao)裝置進(jin)入回轉(zhuan)滾(gun)筒的內(nei)層(ceng)(ceng)(ceng),實(shi)現順流烘干(gan)(gan)(gan),物(wu)(wu)料(liao)(liao)在(zai)內(nei)層(ceng)(ceng)(ceng)的抄板(ban)下不斷(duan)抄起、散落(luo)呈螺(luo)旋(xuan)行(xing)(xing)進(jin)式實(shi)現熱(re)交(jiao)換,物(wu)(wu)料(liao)(liao)移動至(zhi)內(nei)層(ceng)(ceng)(ceng)的另一(yi)端(duan)進(jin)入中(zhong)(zhong)層(ceng)(ceng)(ceng),進(jin)行(xing)(xing)逆流烘干(gan)(gan)(gan),物(wu)(wu)料(liao)(liao)在(zai)中(zhong)(zhong)層(ceng)(ceng)(ceng)不斷(duan)地被反(fan)復揚(yang)進(jin),呈進(jin)兩(liang)步退一(yi)步的行(xing)(xing)進(jin)方(fang)式,物(wu)(wu)料(liao)(liao)在(zai)中(zhong)(zhong)層(ceng)(ceng)(ceng)既充(chong)分(fen)吸收(shou)內(nei)層(ceng)(ceng)(ceng)滾(gun)筒散發的熱(re)量,又吸收(shou)中(zhong)(zhong)層(ceng)(ceng)(ceng)滾(gun)筒的熱(re)量,同時又延(yan)長了干(gan)(gan)(gan)燥(zao)(zao)時間,物(wu)(wu)料(liao)(liao)在(zai)此(ci)達(da)到(dao)干(gan)(gan)(gan)燥(zao)(zao)狀態。物(wu)(wu)料(liao)(liao)行(xing)(xing)至(zhi)中(zhong)(zhong)層(ceng)(ceng)(ceng)另一(yi)端(duan)而(er)(er)落(luo)入外層(ceng)(ceng)(ceng),物(wu)(wu)料(liao)(liao)在(zai)外層(ceng)(ceng)(ceng)滾(gun)筒內(nei)呈矩形多回路方(fang)式行(xing)(xing)進(jin),達(da)到(dao)干(gan)(gan)(gan)燥(zao)(zao)效(xiao)果(guo)的物(wu)(wu)料(liao)(liao)在(zai)熱(re)風作(zuo)用下快速行(xing)(xing)進(jin)排(pai)出滾(gun)筒,沒(mei)有達(da)到(dao)干(gan)(gan)(gan)燥(zao)(zao)效(xiao)果(guo)的濕物(wu)(wu)料(liao)(liao)因自重而(er)(er)不能快速行(xing)(xing)進(jin),物(wu)(wu)料(liao)(liao)在(zai)此(ci)矩形抄板(ban)內(nei)進(jin)行(xing)(xing)充(chong)分(fen)干(gan)(gan)(gan)燥(zao)(zao),由(you)此(ci)完成干(gan)(gan)(gan)燥(zao)(zao)目(mu)的。
