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(bu)分由三(san)個(ge)同(tong)軸水平放置(zhi)的(de)內、中、外(wai)筒(tong)套疊組成(cheng),這就使筒(tong)體的(de)截面(mian)得到充分的(de)利用。其筒(tong)體外(wai)形總長度約(yue)為(wei)與之相(xiang)當(dang)的(de)單筒(tong)的(de)30-35%。從(cong)而大幅度地(di)減少(shao)占地(di)面(mian)積和廠房(fang)建筑面(mian)積。
該機(ji)(ji)的(de)支承裝置,是在外筒上(shang)輪帶與(yu)(yu)托輪支承,由電(dian)機(ji)(ji)直接帶動托輪。通(tong)過托輪與(yu)(yu)輪帶摩擦(ca),使筒體轉動。該機(ji)(ji)總體結(jie)構緊湊、合理(li)、簡單(dan),為便(bian)于磨損件的(de)檢修更換,在中間設(she)計成軸(zhou)向剖分式(shi),用(yong)螺栓(shuan)固定連接。
工作原理
物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)由(you)(you)供料(liao)(liao)(liao)裝置進入回轉滾(gun)(gun)筒的(de)內(nei)層(ceng)(ceng)(ceng),實(shi)現(xian)順(shun)流(liu)烘干(gan),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)(zai)內(nei)層(ceng)(ceng)(ceng)的(de)抄板下(xia)不(bu)斷抄起、散落呈螺旋行(xing)(xing)(xing)進式(shi)實(shi)現(xian)熱(re)交換,物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)移動至內(nei)層(ceng)(ceng)(ceng)的(de)另一端進入中(zhong)層(ceng)(ceng)(ceng),進行(xing)(xing)(xing)逆流(liu)烘干(gan),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)(zai)中(zhong)層(ceng)(ceng)(ceng)不(bu)斷地(di)被反(fan)復揚進,呈進兩(liang)步退一步的(de)行(xing)(xing)(xing)進方式(shi),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)(zai)中(zhong)層(ceng)(ceng)(ceng)既充(chong)分(fen)吸(xi)收內(nei)層(ceng)(ceng)(ceng)滾(gun)(gun)筒散發的(de)熱(re)量,又吸(xi)收中(zhong)層(ceng)(ceng)(ceng)滾(gun)(gun)筒的(de)熱(re)量,同時(shi)又延(yan)長了干(gan)燥(zao)時(shi)間(jian),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)(zai)此達(da)到干(gan)燥(zao)狀態。物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)行(xing)(xing)(xing)至中(zhong)層(ceng)(ceng)(ceng)另一端而落入外層(ceng)(ceng)(ceng),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)(zai)外層(ceng)(ceng)(ceng)滾(gun)(gun)筒內(nei)呈矩(ju)形(xing)多回路方式(shi)行(xing)(xing)(xing)進,達(da)到干(gan)燥(zao)效(xiao)果的(de)物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)(zai)熱(re)風作用下(xia)快速行(xing)(xing)(xing)進排(pai)出滾(gun)(gun)筒,沒(mei)有達(da)到干(gan)燥(zao)效(xiao)果的(de)濕物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)因自重而不(bu)能快速行(xing)(xing)(xing)進,物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)(zai)此矩(ju)形(xing)抄板內(nei)進行(xing)(xing)(xing)充(chong)分(fen)干(gan)燥(zao),由(you)(you)此完成(cheng)干(gan)燥(zao)目的(de)。
