產品結構
三筒式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。
烘干機筒體部分由(you)三個同(tong)軸水平放(fang)置的(de)內(nei)、中、外筒套疊(die)組成(cheng),這就(jiu)使筒體的(de)截面(mian)得(de)到充分的(de)利用。其筒體外形總長度約為與之相當的(de)單筒的(de)30-35%。從(cong)而大幅(fu)度地(di)減少占地(di)面(mian)積和廠(chang)房建(jian)筑面(mian)積。
該機(ji)的支承裝置,是在外筒上輪(lun)(lun)帶與托(tuo)輪(lun)(lun)支承,由電機(ji)直接(jie)帶動托(tuo)輪(lun)(lun)。通(tong)過托(tuo)輪(lun)(lun)與輪(lun)(lun)帶摩擦(ca),使筒體(ti)轉動。該機(ji)總體(ti)結構緊湊、合理、簡單,為便于磨(mo)損件的檢(jian)修更換,在中間設計成軸向剖分式,用螺栓固定連接(jie)。
工作(zuo)原理
物(wu)(wu)(wu)料(liao)(liao)由供料(liao)(liao)裝置進(jin)入(ru)回轉滾筒的(de)(de)內(nei)(nei)層(ceng)(ceng)(ceng)(ceng)(ceng),實(shi)現(xian)順流烘(hong)(hong)干(gan)(gan),物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)(zai)內(nei)(nei)層(ceng)(ceng)(ceng)(ceng)(ceng)的(de)(de)抄板下(xia)不(bu)斷(duan)抄起、散落呈螺旋(xuan)行(xing)進(jin)式(shi)(shi)(shi)實(shi)現(xian)熱交換,物(wu)(wu)(wu)料(liao)(liao)移動至內(nei)(nei)層(ceng)(ceng)(ceng)(ceng)(ceng)的(de)(de)另一(yi)(yi)端進(jin)入(ru)中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng),進(jin)行(xing)逆流烘(hong)(hong)干(gan)(gan),物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)(zai)中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng)不(bu)斷(duan)地被(bei)反復(fu)揚進(jin),呈進(jin)兩步(bu)退一(yi)(yi)步(bu)的(de)(de)行(xing)進(jin)方式(shi)(shi)(shi),物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)(zai)中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng)既充分吸收內(nei)(nei)層(ceng)(ceng)(ceng)(ceng)(ceng)滾筒散發(fa)的(de)(de)熱量,又(you)吸收中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng)滾筒的(de)(de)熱量,同時又(you)延長了干(gan)(gan)燥時間(jian),物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)(zai)此(ci)達到干(gan)(gan)燥狀(zhuang)態(tai)。物(wu)(wu)(wu)料(liao)(liao)行(xing)至中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng)另一(yi)(yi)端而(er)落入(ru)外(wai)層(ceng)(ceng)(ceng)(ceng)(ceng),物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)(zai)外(wai)層(ceng)(ceng)(ceng)(ceng)(ceng)滾筒內(nei)(nei)呈矩形多回路方式(shi)(shi)(shi)行(xing)進(jin),達到干(gan)(gan)燥效果(guo)的(de)(de)物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)(zai)熱風(feng)作(zuo)用下(xia)快(kuai)(kuai)速行(xing)進(jin)排出滾筒,沒有(you)達到干(gan)(gan)燥效果(guo)的(de)(de)濕物(wu)(wu)(wu)料(liao)(liao)因自重而(er)不(bu)能(neng)快(kuai)(kuai)速行(xing)進(jin),物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)(zai)此(ci)矩形抄板內(nei)(nei)進(jin)行(xing)充分干(gan)(gan)燥,由此(ci)完(wan)成干(gan)(gan)燥目的(de)(de)。
