產品結(jie)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(hong)干機筒體(ti)部分(fen)由三個同軸水平放(fang)置的內、中、外(wai)筒套(tao)疊組(zu)成,這就使筒體(ti)的截面(mian)得到充(chong)分(fen)的利用。其筒體(ti)外(wai)形總長度約為與(yu)之相當的單筒的30-35%。從而大幅度地(di)減少占地(di)面(mian)積(ji)和廠房建筑面(mian)積(ji)。
該機(ji)(ji)(ji)的(de)支承(cheng)(cheng)裝(zhuang)置,是在(zai)外筒上輪帶(dai)(dai)與托(tuo)輪支承(cheng)(cheng),由電(dian)機(ji)(ji)(ji)直接(jie)帶(dai)(dai)動托(tuo)輪。通(tong)過托(tuo)輪與輪帶(dai)(dai)摩擦(ca),使筒體轉動。該機(ji)(ji)(ji)總(zong)體結構(gou)緊湊、合理、簡(jian)單(dan),為(wei)便于磨損件的(de)檢修更(geng)換(huan),在(zai)中間設計成軸(zhou)向剖(pou)分式,用螺栓固定連接(jie)。
工作原理
物(wu)(wu)料(liao)由(you)供料(liao)裝置進(jin)(jin)(jin)(jin)入(ru)回轉滾(gun)筒的(de)內(nei)層(ceng)(ceng)(ceng)(ceng)(ceng),實現(xian)順流烘(hong)干,物(wu)(wu)料(liao)在(zai)(zai)內(nei)層(ceng)(ceng)(ceng)(ceng)(ceng)的(de)抄板下不斷抄起(qi)、散落(luo)呈(cheng)螺旋(xuan)行(xing)進(jin)(jin)(jin)(jin)式實現(xian)熱(re)交換,物(wu)(wu)料(liao)移動至內(nei)層(ceng)(ceng)(ceng)(ceng)(ceng)的(de)另(ling)一(yi)端進(jin)(jin)(jin)(jin)入(ru)中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng),進(jin)(jin)(jin)(jin)行(xing)逆流烘(hong)干,物(wu)(wu)料(liao)在(zai)(zai)中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng)不斷地被反復揚(yang)進(jin)(jin)(jin)(jin),呈(cheng)進(jin)(jin)(jin)(jin)兩步退一(yi)步的(de)行(xing)進(jin)(jin)(jin)(jin)方式,物(wu)(wu)料(liao)在(zai)(zai)中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng)既充分吸收內(nei)層(ceng)(ceng)(ceng)(ceng)(ceng)滾(gun)筒散發的(de)熱(re)量(liang),又吸收中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng)滾(gun)筒的(de)熱(re)量(liang),同時(shi)又延長(chang)了干燥時(shi)間,物(wu)(wu)料(liao)在(zai)(zai)此達(da)到干燥狀態。物(wu)(wu)料(liao)行(xing)至中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng)另(ling)一(yi)端而落(luo)入(ru)外層(ceng)(ceng)(ceng)(ceng)(ceng),物(wu)(wu)料(liao)在(zai)(zai)外層(ceng)(ceng)(ceng)(ceng)(ceng)滾(gun)筒內(nei)呈(cheng)矩(ju)形(xing)多回路方式行(xing)進(jin)(jin)(jin)(jin),達(da)到干燥效(xiao)果的(de)物(wu)(wu)料(liao)在(zai)(zai)熱(re)風作(zuo)用下快速行(xing)進(jin)(jin)(jin)(jin)排出滾(gun)筒,沒有(you)達(da)到干燥效(xiao)果的(de)濕物(wu)(wu)料(liao)因自重而不能快速行(xing)進(jin)(jin)(jin)(jin),物(wu)(wu)料(liao)在(zai)(zai)此矩(ju)形(xing)抄板內(nei)進(jin)(jin)(jin)(jin)行(xing)充分干燥,由(you)此完成(cheng)干燥目(mu)的(de)。
