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(tong)體部分由三(san)個同軸水平(ping)放置的(de)內、中、外筒(tong)套(tao)疊組(zu)成,這就使筒(tong)體的(de)截面(mian)得到(dao)充分的(de)利用。其筒(tong)體外形總長度約為與之相當的(de)單筒(tong)的(de)30-35%。從而大幅度地減少占(zhan)地面(mian)積(ji)和(he)廠房建筑面(mian)積(ji)。
該(gai)機(ji)的(de)支承裝置,是在外(wai)筒(tong)上輪帶(dai)與(yu)托輪支承,由(you)電機(ji)直接帶(dai)動托輪。通過托輪與(yu)輪帶(dai)摩擦(ca),使筒(tong)體轉動。該(gai)機(ji)總體結構緊湊、合理(li)、簡單,為便于磨(mo)損件的(de)檢修更換,在中間設計成軸向剖分式,用(yong)螺栓固定(ding)連(lian)接。
工作原理
物(wu)(wu)(wu)料(liao)(liao)(liao)由供(gong)料(liao)(liao)(liao)裝置(zhi)進(jin)(jin)(jin)(jin)(jin)入(ru)回轉滾(gun)筒(tong)的內(nei)層(ceng)(ceng)(ceng)(ceng),實現順流(liu)烘(hong)干(gan)(gan)(gan)(gan),物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)內(nei)層(ceng)(ceng)(ceng)(ceng)的抄板下(xia)不(bu)斷抄起、散落(luo)(luo)呈(cheng)螺(luo)旋(xuan)行(xing)(xing)進(jin)(jin)(jin)(jin)(jin)式(shi)實現熱(re)交換,物(wu)(wu)(wu)料(liao)(liao)(liao)移動(dong)至內(nei)層(ceng)(ceng)(ceng)(ceng)的另(ling)(ling)一端(duan)進(jin)(jin)(jin)(jin)(jin)入(ru)中層(ceng)(ceng)(ceng)(ceng),進(jin)(jin)(jin)(jin)(jin)行(xing)(xing)逆流(liu)烘(hong)干(gan)(gan)(gan)(gan),物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)中層(ceng)(ceng)(ceng)(ceng)不(bu)斷地被(bei)反復揚進(jin)(jin)(jin)(jin)(jin),呈(cheng)進(jin)(jin)(jin)(jin)(jin)兩步退一步的行(xing)(xing)進(jin)(jin)(jin)(jin)(jin)方式(shi),物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)中層(ceng)(ceng)(ceng)(ceng)既充(chong)分吸(xi)(xi)收內(nei)層(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)散發的熱(re)量,又吸(xi)(xi)收中層(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)的熱(re)量,同時又延(yan)長了干(gan)(gan)(gan)(gan)燥(zao)(zao)時間(jian),物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)此達到(dao)干(gan)(gan)(gan)(gan)燥(zao)(zao)狀(zhuang)態。物(wu)(wu)(wu)料(liao)(liao)(liao)行(xing)(xing)至中層(ceng)(ceng)(ceng)(ceng)另(ling)(ling)一端(duan)而落(luo)(luo)入(ru)外層(ceng)(ceng)(ceng)(ceng),物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)外層(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)內(nei)呈(cheng)矩(ju)形多回路方式(shi)行(xing)(xing)進(jin)(jin)(jin)(jin)(jin),達到(dao)干(gan)(gan)(gan)(gan)燥(zao)(zao)效(xiao)果的物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)熱(re)風作(zuo)用下(xia)快速(su)行(xing)(xing)進(jin)(jin)(jin)(jin)(jin)排出滾(gun)筒(tong),沒有達到(dao)干(gan)(gan)(gan)(gan)燥(zao)(zao)效(xiao)果的濕物(wu)(wu)(wu)料(liao)(liao)(liao)因(yin)自(zi)重而不(bu)能快速(su)行(xing)(xing)進(jin)(jin)(jin)(jin)(jin),物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)此矩(ju)形抄板內(nei)進(jin)(jin)(jin)(jin)(jin)行(xing)(xing)充(chong)分干(gan)(gan)(gan)(gan)燥(zao)(zao),由此完成干(gan)(gan)(gan)(gan)燥(zao)(zao)目的。
