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。
烘干機筒(tong)體部分(fen)由三個(ge)同軸水平放置的內、中、外筒(tong)套疊(die)組成,這(zhe)就使筒(tong)體的截面(mian)(mian)得到(dao)充分(fen)的利用(yong)。其筒(tong)體外形總長度約為與之(zhi)相(xiang)當的單筒(tong)的30-35%。從而大幅度地(di)減(jian)少占地(di)面(mian)(mian)積和廠房建(jian)筑面(mian)(mian)積。
該機的支(zhi)承裝置,是在外筒上輪(lun)帶(dai)與(yu)托輪(lun)支(zhi)承,由電機直接(jie)帶(dai)動(dong)托輪(lun)。通過托輪(lun)與(yu)輪(lun)帶(dai)摩擦,使(shi)筒體轉(zhuan)動(dong)。該機總體結(jie)構緊湊、合理、簡(jian)單,為便于磨損件的檢(jian)修更(geng)換,在中間設計成(cheng)軸向剖分(fen)式,用螺栓固(gu)定連接(jie)。
工作原理
物(wu)(wu)(wu)料(liao)(liao)由(you)供料(liao)(liao)裝(zhuang)置進(jin)(jin)入(ru)(ru)回(hui)轉滾(gun)筒(tong)(tong)的(de)內(nei)(nei)層(ceng),實(shi)現(xian)順流烘干(gan)(gan)(gan)(gan)(gan),物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)內(nei)(nei)層(ceng)的(de)抄(chao)板下(xia)不斷抄(chao)起、散落呈螺(luo)旋行(xing)進(jin)(jin)式(shi)實(shi)現(xian)熱交換,物(wu)(wu)(wu)料(liao)(liao)移動(dong)至(zhi)內(nei)(nei)層(ceng)的(de)另一端進(jin)(jin)入(ru)(ru)中(zhong)(zhong)層(ceng),進(jin)(jin)行(xing)逆流烘干(gan)(gan)(gan)(gan)(gan),物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)中(zhong)(zhong)層(ceng)不斷地被反(fan)復揚(yang)進(jin)(jin),呈進(jin)(jin)兩步退一步的(de)行(xing)進(jin)(jin)方(fang)式(shi),物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)中(zhong)(zhong)層(ceng)既充(chong)(chong)分(fen)吸(xi)(xi)收(shou)內(nei)(nei)層(ceng)滾(gun)筒(tong)(tong)散發(fa)的(de)熱量,又(you)吸(xi)(xi)收(shou)中(zhong)(zhong)層(ceng)滾(gun)筒(tong)(tong)的(de)熱量,同時又(you)延(yan)長了干(gan)(gan)(gan)(gan)(gan)燥(zao)(zao)時間,物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)此(ci)達到(dao)干(gan)(gan)(gan)(gan)(gan)燥(zao)(zao)狀態。物(wu)(wu)(wu)料(liao)(liao)行(xing)至(zhi)中(zhong)(zhong)層(ceng)另一端而落入(ru)(ru)外層(ceng),物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)外層(ceng)滾(gun)筒(tong)(tong)內(nei)(nei)呈矩形多(duo)回(hui)路方(fang)式(shi)行(xing)進(jin)(jin),達到(dao)干(gan)(gan)(gan)(gan)(gan)燥(zao)(zao)效果的(de)物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)熱風(feng)作用下(xia)快(kuai)速行(xing)進(jin)(jin)排出滾(gun)筒(tong)(tong),沒有達到(dao)干(gan)(gan)(gan)(gan)(gan)燥(zao)(zao)效果的(de)濕物(wu)(wu)(wu)料(liao)(liao)因自重而不能快(kuai)速行(xing)進(jin)(jin),物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)此(ci)矩形抄(chao)板內(nei)(nei)進(jin)(jin)行(xing)充(chong)(chong)分(fen)干(gan)(gan)(gan)(gan)(gan)燥(zao)(zao),由(you)此(ci)完成干(gan)(gan)(gan)(gan)(gan)燥(zao)(zao)目(mu)的(de)。
