產(chan)品(pin)結構
三筒烘(hong)(hong)干機(ji)是通(tong)過對單(dan)筒烘(hong)(hong)干機(ji)的單(dan)筒體(ti)(ti)改(gai)為套(tao)疊(die)在一起(qi)的三筒,以(yi)縮短烘(hong)(hong)干機(ji)體(ti)(ti)的外(wai)形尺(chi)寸。該機(ji)工作時,物料和(he)熱(re)氣流依次進入(ru)內至外(wai)筒體(ti)(ti),在機(ji)體(ti)(ti)Z形往復折流后(hou),充分利用熱(re)能(neng)烘(hong)(hong)干物料后(hou)再卸出(chu)。
烘(hong)干機筒(tong)(tong)(tong)體(ti)部分由三個同軸(zhou)水平放置的(de)內、中、外(wai)筒(tong)(tong)(tong)套(tao)疊組成,這(zhe)就(jiu)使筒(tong)(tong)(tong)體(ti)的(de)截面得到充分的(de)利用。其筒(tong)(tong)(tong)體(ti)外(wai)形總(zong)長度約(yue)為與(yu)之相當的(de)單筒(tong)(tong)(tong)的(de)30-35%。從(cong)而大幅度地減(jian)少占地面積和廠房(fang)建筑面積。
該機(ji)(ji)的(de)支承裝(zhuang)置,是在(zai)外筒(tong)上輪(lun)帶(dai)與托輪(lun)支承,由電(dian)機(ji)(ji)直接(jie)(jie)帶(dai)動(dong)托輪(lun)。通過(guo)托輪(lun)與輪(lun)帶(dai)摩擦,使筒(tong)體轉動(dong)。該機(ji)(ji)總體結構緊湊、合理、簡單,為便于(yu)磨損件的(de)檢修更(geng)換,在(zai)中間設(she)計成(cheng)軸(zhou)向剖分式,用(yong)螺栓固定連接(jie)(jie)。
工作原理
物(wu)料由供(gong)料裝置進(jin)(jin)入回轉滾(gun)(gun)筒(tong)的(de)(de)(de)內層(ceng)(ceng)(ceng)(ceng),實現順流烘干(gan)(gan),物(wu)料在(zai)(zai)內層(ceng)(ceng)(ceng)(ceng)的(de)(de)(de)抄(chao)板(ban)下不斷抄(chao)起、散落呈螺旋(xuan)行(xing)(xing)進(jin)(jin)式(shi)實現熱(re)(re)交換,物(wu)料移動(dong)至(zhi)內層(ceng)(ceng)(ceng)(ceng)的(de)(de)(de)另一端(duan)進(jin)(jin)入中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng),進(jin)(jin)行(xing)(xing)逆流烘干(gan)(gan),物(wu)料在(zai)(zai)中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)不斷地(di)被反復揚進(jin)(jin),呈進(jin)(jin)兩步退一步的(de)(de)(de)行(xing)(xing)進(jin)(jin)方式(shi),物(wu)料在(zai)(zai)中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)既充分吸收內層(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)散發的(de)(de)(de)熱(re)(re)量,又吸收中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)的(de)(de)(de)熱(re)(re)量,同(tong)時(shi)又延(yan)長了(le)干(gan)(gan)燥(zao)時(shi)間,物(wu)料在(zai)(zai)此達(da)到干(gan)(gan)燥(zao)狀態(tai)。物(wu)料行(xing)(xing)至(zhi)中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)另一端(duan)而落入外層(ceng)(ceng)(ceng)(ceng),物(wu)料在(zai)(zai)外層(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)內呈矩(ju)形多回路方式(shi)行(xing)(xing)進(jin)(jin),達(da)到干(gan)(gan)燥(zao)效果(guo)的(de)(de)(de)物(wu)料在(zai)(zai)熱(re)(re)風作用下快(kuai)速行(xing)(xing)進(jin)(jin)排出滾(gun)(gun)筒(tong),沒有達(da)到干(gan)(gan)燥(zao)效果(guo)的(de)(de)(de)濕物(wu)料因自重(zhong)而不能(neng)快(kuai)速行(xing)(xing)進(jin)(jin),物(wu)料在(zai)(zai)此矩(ju)形抄(chao)板(ban)內進(jin)(jin)行(xing)(xing)充分干(gan)(gan)燥(zao),由此完成干(gan)(gan)燥(zao)目的(de)(de)(de)。
