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(ji)筒(tong)(tong)(tong)體(ti)部分由三個(ge)同軸水平放置的(de)(de)內、中、外筒(tong)(tong)(tong)套(tao)疊組成,這(zhe)就(jiu)使筒(tong)(tong)(tong)體(ti)的(de)(de)截(jie)面(mian)得到充分的(de)(de)利用。其(qi)筒(tong)(tong)(tong)體(ti)外形總(zong)長度約為(wei)與之(zhi)相當的(de)(de)單筒(tong)(tong)(tong)的(de)(de)30-35%。從(cong)而(er)大幅度地(di)減少(shao)占地(di)面(mian)積和廠房建(jian)筑(zhu)面(mian)積。
該(gai)機的(de)支承(cheng)裝(zhuang)置,是在外筒上輪(lun)帶與托(tuo)(tuo)輪(lun)支承(cheng),由電機直接帶動托(tuo)(tuo)輪(lun)。通過(guo)托(tuo)(tuo)輪(lun)與輪(lun)帶摩擦(ca),使筒體轉動。該(gai)機總體結構緊湊、合理、簡單,為便于磨損件的(de)檢修更(geng)換,在中間(jian)設計成(cheng)軸向(xiang)剖分(fen)式(shi),用(yong)螺栓固(gu)定連接。
工作原理
物(wu)(wu)(wu)料(liao)(liao)(liao)由供料(liao)(liao)(liao)裝置(zhi)進(jin)入回轉滾(gun)(gun)(gun)筒的(de)(de)內(nei)層(ceng)(ceng),實現(xian)順流烘干(gan)(gan),物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)內(nei)層(ceng)(ceng)的(de)(de)抄板下(xia)不(bu)斷抄起、散落(luo)(luo)呈(cheng)螺(luo)旋行(xing)(xing)進(jin)式實現(xian)熱交換,物(wu)(wu)(wu)料(liao)(liao)(liao)移動至(zhi)內(nei)層(ceng)(ceng)的(de)(de)另一端進(jin)入中(zhong)(zhong)層(ceng)(ceng),進(jin)行(xing)(xing)逆(ni)流烘干(gan)(gan),物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)中(zhong)(zhong)層(ceng)(ceng)不(bu)斷地(di)被反復揚進(jin),呈(cheng)進(jin)兩步(bu)退一步(bu)的(de)(de)行(xing)(xing)進(jin)方(fang)式,物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)中(zhong)(zhong)層(ceng)(ceng)既(ji)充分吸(xi)收內(nei)層(ceng)(ceng)滾(gun)(gun)(gun)筒散發(fa)的(de)(de)熱量(liang),又吸(xi)收中(zhong)(zhong)層(ceng)(ceng)滾(gun)(gun)(gun)筒的(de)(de)熱量(liang),同時(shi)又延(yan)長了干(gan)(gan)燥時(shi)間(jian),物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)此達(da)到(dao)干(gan)(gan)燥狀(zhuang)態。物(wu)(wu)(wu)料(liao)(liao)(liao)行(xing)(xing)至(zhi)中(zhong)(zhong)層(ceng)(ceng)另一端而(er)落(luo)(luo)入外層(ceng)(ceng),物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)外層(ceng)(ceng)滾(gun)(gun)(gun)筒內(nei)呈(cheng)矩(ju)形(xing)多(duo)回路方(fang)式行(xing)(xing)進(jin),達(da)到(dao)干(gan)(gan)燥效(xiao)果的(de)(de)物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)熱風(feng)作用下(xia)快速行(xing)(xing)進(jin)排出滾(gun)(gun)(gun)筒,沒有達(da)到(dao)干(gan)(gan)燥效(xiao)果的(de)(de)濕物(wu)(wu)(wu)料(liao)(liao)(liao)因(yin)自重而(er)不(bu)能快速行(xing)(xing)進(jin),物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)此矩(ju)形(xing)抄板內(nei)進(jin)行(xing)(xing)充分干(gan)(gan)燥,由此完成干(gan)(gan)燥目的(de)(de)。
