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(tong)(tong)(tong)體部分由(you)三個同軸水平放置的(de)內、中、外筒(tong)(tong)(tong)套疊組成,這就使筒(tong)(tong)(tong)體的(de)截面得到充分的(de)利用。其筒(tong)(tong)(tong)體外形總長度約為與之相(xiang)當的(de)單筒(tong)(tong)(tong)的(de)30-35%。從而大幅度地(di)減少占地(di)面積和廠房建筑(zhu)面積。
該機的支承裝置,是在(zai)外筒上(shang)輪帶(dai)與(yu)托輪支承,由(you)電機直接(jie)帶(dai)動(dong)(dong)托輪。通(tong)過(guo)托輪與(yu)輪帶(dai)摩擦,使筒體轉(zhuan)動(dong)(dong)。該機總體結構緊湊(cou)、合(he)理、簡(jian)單(dan),為便于磨(mo)損件的檢(jian)修(xiu)更換,在(zai)中間設計成軸向剖(pou)分式,用(yong)螺栓固(gu)定連接(jie)。
工作原理
物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)由供(gong)料(liao)(liao)(liao)(liao)(liao)裝置進(jin)(jin)入回轉滾(gun)筒(tong)(tong)的(de)(de)內層(ceng)(ceng),實現順流(liu)烘干(gan)(gan)(gan)(gan),物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)(zai)內層(ceng)(ceng)的(de)(de)抄板(ban)下不(bu)斷抄起、散落呈螺旋行(xing)(xing)進(jin)(jin)式(shi)(shi)實現熱交(jiao)換,物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)移動(dong)至內層(ceng)(ceng)的(de)(de)另一端(duan)進(jin)(jin)入中(zhong)(zhong)(zhong)層(ceng)(ceng),進(jin)(jin)行(xing)(xing)逆流(liu)烘干(gan)(gan)(gan)(gan),物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)(zai)中(zhong)(zhong)(zhong)層(ceng)(ceng)不(bu)斷地被反復揚進(jin)(jin),呈進(jin)(jin)兩步(bu)退一步(bu)的(de)(de)行(xing)(xing)進(jin)(jin)方式(shi)(shi),物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)(zai)中(zhong)(zhong)(zhong)層(ceng)(ceng)既充(chong)分吸收內層(ceng)(ceng)滾(gun)筒(tong)(tong)散發的(de)(de)熱量,又吸收中(zhong)(zhong)(zhong)層(ceng)(ceng)滾(gun)筒(tong)(tong)的(de)(de)熱量,同時又延長了干(gan)(gan)(gan)(gan)燥時間(jian),物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)(zai)此達(da)到(dao)(dao)干(gan)(gan)(gan)(gan)燥狀態。物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)行(xing)(xing)至中(zhong)(zhong)(zhong)層(ceng)(ceng)另一端(duan)而落入外層(ceng)(ceng),物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)(zai)外層(ceng)(ceng)滾(gun)筒(tong)(tong)內呈矩形(xing)多(duo)回路方式(shi)(shi)行(xing)(xing)進(jin)(jin),達(da)到(dao)(dao)干(gan)(gan)(gan)(gan)燥效果的(de)(de)物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)(zai)熱風作用下快速(su)行(xing)(xing)進(jin)(jin)排出(chu)滾(gun)筒(tong)(tong),沒有達(da)到(dao)(dao)干(gan)(gan)(gan)(gan)燥效果的(de)(de)濕(shi)物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)因自重而不(bu)能快速(su)行(xing)(xing)進(jin)(jin),物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)(zai)此矩形(xing)抄板(ban)內進(jin)(jin)行(xing)(xing)充(chong)分干(gan)(gan)(gan)(gan)燥,由此完(wan)成干(gan)(gan)(gan)(gan)燥目(mu)的(de)(de)。
