產品結構
大型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(gan)機筒(tong)(tong)體部分由三個同(tong)軸水平放(fang)置的(de)(de)內(nei)、中、外筒(tong)(tong)套(tao)疊組成,這就使(shi)筒(tong)(tong)體的(de)(de)截面得(de)到充分的(de)(de)利用(yong)。其筒(tong)(tong)體外形總(zong)長(chang)度(du)約為與之相(xiang)當的(de)(de)單筒(tong)(tong)的(de)(de)30-35%。從而大幅度(du)地(di)減少占地(di)面積(ji)(ji)和廠房建筑面積(ji)(ji)。
該機的支(zhi)承(cheng)裝置,是在外(wai)筒(tong)(tong)上輪帶與(yu)托(tuo)輪支(zhi)承(cheng),由電機直接(jie)帶動托(tuo)輪。通過托(tuo)輪與(yu)輪帶摩擦,使(shi)筒(tong)(tong)體轉動。該機總體結構緊湊、合理、簡單,為(wei)便于磨損件的檢(jian)修更(geng)換(huan),在中間(jian)設(she)計(ji)成軸(zhou)向剖分式(shi),用螺栓固(gu)定連接(jie)。
工作(zuo)原理
物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)由(you)(you)供料(liao)(liao)(liao)(liao)裝置進(jin)入回(hui)轉(zhuan)滾筒(tong)的(de)內層(ceng)(ceng)(ceng)(ceng),實現(xian)順流(liu)(liu)烘干(gan),物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)內層(ceng)(ceng)(ceng)(ceng)的(de)抄(chao)板下(xia)不斷抄(chao)起、散落(luo)(luo)呈(cheng)螺旋(xuan)行(xing)進(jin)式(shi)(shi)實現(xian)熱(re)(re)交換,物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)移動至(zhi)內層(ceng)(ceng)(ceng)(ceng)的(de)另(ling)一(yi)端(duan)進(jin)入中(zhong)層(ceng)(ceng)(ceng)(ceng),進(jin)行(xing)逆流(liu)(liu)烘干(gan),物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)中(zhong)層(ceng)(ceng)(ceng)(ceng)不斷地被(bei)反復(fu)揚進(jin),呈(cheng)進(jin)兩步退一(yi)步的(de)行(xing)進(jin)方(fang)式(shi)(shi),物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)中(zhong)層(ceng)(ceng)(ceng)(ceng)既充分(fen)吸收內層(ceng)(ceng)(ceng)(ceng)滾筒(tong)散發的(de)熱(re)(re)量(liang),又(you)吸收中(zhong)層(ceng)(ceng)(ceng)(ceng)滾筒(tong)的(de)熱(re)(re)量(liang),同時(shi)又(you)延長了(le)干(gan)燥時(shi)間(jian),物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)此(ci)達(da)(da)(da)到干(gan)燥狀態。物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)行(xing)至(zhi)中(zhong)層(ceng)(ceng)(ceng)(ceng)另(ling)一(yi)端(duan)而落(luo)(luo)入外層(ceng)(ceng)(ceng)(ceng),物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)外層(ceng)(ceng)(ceng)(ceng)滾筒(tong)內呈(cheng)矩(ju)形(xing)多回(hui)路方(fang)式(shi)(shi)行(xing)進(jin),達(da)(da)(da)到干(gan)燥效果的(de)物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)熱(re)(re)風作用下(xia)快速行(xing)進(jin)排(pai)出滾筒(tong),沒有達(da)(da)(da)到干(gan)燥效果的(de)濕(shi)物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)因(yin)自重(zhong)而不能快速行(xing)進(jin),物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)此(ci)矩(ju)形(xing)抄(chao)板內進(jin)行(xing)充分(fen)干(gan)燥,由(you)(you)此(ci)完成(cheng)干(gan)燥目的(de)。
