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)體部分由三個同軸水平放置的內、中、外筒(tong)套疊組成，這就使(shi)筒(tong)體的截(jie)面(mian)得到(dao)充分的利用。其筒(tong)體外形總長度(du)約為與之(zhi)相當的單(dan)筒(tong)的30-35%。從而大幅度(du)地減少占地面(mian)積和(he)廠房建(jian)筑面(mian)積。

該(gai)機(ji)的支(zhi)承(cheng)(cheng)裝置，是在外(wai)筒上輪帶(dai)與(yu)托輪支(zhi)承(cheng)(cheng)，由電(dian)機(ji)直接帶(dai)動托輪。通過托輪與(yu)輪帶(dai)摩擦(ca)，使(shi)筒體轉動。該(gai)機(ji)總(zong)體結構緊湊(cou)、合理、簡單，為便(bian)于(yu)磨損件的檢(jian)修更(geng)換，在中間設計成軸向剖分式(shi)，用螺栓固定連接。

工作原理

物(wu)(wu)料由供料裝置進(jin)入(ru)回(hui)轉(zhuan)滾(gun)筒(tong)(tong)(tong)的(de)(de)(de)內(nei)層(ceng)(ceng),實(shi)現(xian)順流烘干(gan)(gan),物(wu)(wu)料在內(nei)層(ceng)(ceng)的(de)(de)(de)抄板下不(bu)斷抄起、散落呈(cheng)(cheng)螺旋行(xing)(xing)進(jin)式(shi)實(shi)現(xian)熱交(jiao)換，物(wu)(wu)料移動(dong)至內(nei)層(ceng)(ceng)的(de)(de)(de)另一(yi)端進(jin)入(ru)中(zhong)(zhong)層(ceng)(ceng)，進(jin)行(xing)(xing)逆流烘干(gan)(gan)，物(wu)(wu)料在中(zhong)(zhong)層(ceng)(ceng)不(bu)斷地被反(fan)復揚進(jin)，呈(cheng)(cheng)進(jin)兩步退一(yi)步的(de)(de)(de)行(xing)(xing)進(jin)方式(shi)，物(wu)(wu)料在中(zhong)(zhong)層(ceng)(ceng)既充分吸收(shou)內(nei)層(ceng)(ceng)滾(gun)筒(tong)(tong)(tong)散發的(de)(de)(de)熱量，又(you)吸收(shou)中(zhong)(zhong)層(ceng)(ceng)滾(gun)筒(tong)(tong)(tong)的(de)(de)(de)熱量，同時(shi)又(you)延(yan)長了干(gan)(gan)燥(zao)時(shi)間，物(wu)(wu)料在此(ci)達(da)到(dao)干(gan)(gan)燥(zao)狀態。物(wu)(wu)料行(xing)(xing)至中(zhong)(zhong)層(ceng)(ceng)另一(yi)端而落入(ru)外層(ceng)(ceng)，物(wu)(wu)料在外層(ceng)(ceng)滾(gun)筒(tong)(tong)(tong)內(nei)呈(cheng)(cheng)矩形多(duo)回(hui)路方式(shi)行(xing)(xing)進(jin)，達(da)到(dao)干(gan)(gan)燥(zao)效果的(de)(de)(de)物(wu)(wu)料在熱風作(zuo)用下快速行(xing)(xing)進(jin)排出滾(gun)筒(tong)(tong)(tong)，沒有達(da)到(dao)干(gan)(gan)燥(zao)效果的(de)(de)(de)濕物(wu)(wu)料因自重而不(bu)能快速行(xing)(xing)進(jin)，物(wu)(wu)料在此(ci)矩形抄板內(nei)進(jin)行(xing)(xing)充分干(gan)(gan)燥(zao)，由此(ci)完成(cheng)干(gan)(gan)燥(zao)目(mu)的(de)(de)(de)。
