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)體部分由(you)三(san)個同軸水平放置的內、中、外筒(tong)套疊組成,這就使筒(tong)體的截面得到充(chong)分的利用。其筒(tong)體外形總長度約(yue)為與之相當的單筒(tong)的30-35%。從而大幅度地(di)減少占(zhan)地(di)面積和(he)廠房建筑面積。
該(gai)(gai)機的(de)支承裝置(zhi),是在外筒上輪(lun)帶與(yu)托(tuo)(tuo)輪(lun)支承,由(you)電機直接(jie)(jie)帶動托(tuo)(tuo)輪(lun)。通過托(tuo)(tuo)輪(lun)與(yu)輪(lun)帶摩擦,使筒體轉動。該(gai)(gai)機總(zong)體結構緊湊、合理、簡單,為便于磨損(sun)件的(de)檢修更換,在中間設計成軸向剖分(fen)式(shi),用螺(luo)栓固定連(lian)接(jie)(jie)。
工作原理(li)
物(wu)(wu)(wu)(wu)(wu)(wu)(wu)料(liao)(liao)由(you)供料(liao)(liao)裝(zhuang)置進(jin)入(ru)回轉滾(gun)筒(tong)的(de)(de)(de)內層(ceng)(ceng)(ceng)(ceng),實現順流(liu)烘(hong)(hong)干(gan),物(wu)(wu)(wu)(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)內層(ceng)(ceng)(ceng)(ceng)的(de)(de)(de)抄板(ban)下(xia)(xia)不斷抄起、散(san)落呈螺旋行(xing)(xing)(xing)進(jin)式(shi)實現熱(re)交(jiao)換,物(wu)(wu)(wu)(wu)(wu)(wu)(wu)料(liao)(liao)移動至內層(ceng)(ceng)(ceng)(ceng)的(de)(de)(de)另一端進(jin)入(ru)中層(ceng)(ceng)(ceng)(ceng),進(jin)行(xing)(xing)(xing)逆流(liu)烘(hong)(hong)干(gan),物(wu)(wu)(wu)(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)中層(ceng)(ceng)(ceng)(ceng)不斷地被反復揚進(jin),呈進(jin)兩步退一步的(de)(de)(de)行(xing)(xing)(xing)進(jin)方(fang)式(shi),物(wu)(wu)(wu)(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)中層(ceng)(ceng)(ceng)(ceng)既充(chong)分(fen)吸(xi)收內層(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)散(san)發的(de)(de)(de)熱(re)量,又(you)吸(xi)收中層(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)的(de)(de)(de)熱(re)量,同時又(you)延(yan)長了干(gan)燥(zao)時間,物(wu)(wu)(wu)(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)此(ci)(ci)達到干(gan)燥(zao)狀態。物(wu)(wu)(wu)(wu)(wu)(wu)(wu)料(liao)(liao)行(xing)(xing)(xing)至中層(ceng)(ceng)(ceng)(ceng)另一端而落入(ru)外層(ceng)(ceng)(ceng)(ceng),物(wu)(wu)(wu)(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)外層(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)內呈矩形(xing)多回路方(fang)式(shi)行(xing)(xing)(xing)進(jin),達到干(gan)燥(zao)效果(guo)的(de)(de)(de)物(wu)(wu)(wu)(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)熱(re)風作用下(xia)(xia)快速(su)行(xing)(xing)(xing)進(jin)排出滾(gun)筒(tong),沒有達到干(gan)燥(zao)效果(guo)的(de)(de)(de)濕物(wu)(wu)(wu)(wu)(wu)(wu)(wu)料(liao)(liao)因(yin)自重(zhong)而不能快速(su)行(xing)(xing)(xing)進(jin),物(wu)(wu)(wu)(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)此(ci)(ci)矩形(xing)抄板(ban)內進(jin)行(xing)(xing)(xing)充(chong)分(fen)干(gan)燥(zao),由(you)此(ci)(ci)完成(cheng)干(gan)燥(zao)目的(de)(de)(de)。
