產(chan)品(pin)結構(gou)
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(gan)機筒(tong)(tong)體(ti)(ti)部(bu)分由三個(ge)同軸(zhou)水(shui)平放置的(de)內、中、外筒(tong)(tong)套疊(die)組成,這就使筒(tong)(tong)體(ti)(ti)的(de)截(jie)面得到(dao)充分的(de)利(li)用。其筒(tong)(tong)體(ti)(ti)外形總長度約為與之(zhi)相(xiang)當的(de)單筒(tong)(tong)的(de)30-35%。從而(er)大幅度地(di)減少占地(di)面積和廠房建筑(zhu)面積。
該機的(de)支承(cheng)裝置,是在(zai)外筒上輪(lun)帶(dai)與托(tuo)(tuo)輪(lun)支承(cheng),由電機直接(jie)帶(dai)動托(tuo)(tuo)輪(lun)。通過托(tuo)(tuo)輪(lun)與輪(lun)帶(dai)摩擦,使筒體轉動。該機總體結構緊(jin)湊、合理、簡單,為便于磨損件的(de)檢修更換(huan),在(zai)中(zhong)間設計成(cheng)軸向剖分式,用(yong)螺(luo)栓固定(ding)連(lian)接(jie)。
工作原理
物(wu)(wu)(wu)料(liao)(liao)由供料(liao)(liao)裝置進(jin)(jin)(jin)入回(hui)轉滾(gun)筒(tong)的內(nei)(nei)(nei)層(ceng),實(shi)現順流(liu)烘干,物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)內(nei)(nei)(nei)層(ceng)的抄板(ban)下(xia)不斷抄起、散落(luo)呈螺(luo)旋行進(jin)(jin)(jin)式實(shi)現熱(re)(re)交換,物(wu)(wu)(wu)料(liao)(liao)移動至(zhi)(zhi)內(nei)(nei)(nei)層(ceng)的另一(yi)端(duan)進(jin)(jin)(jin)入中(zhong)層(ceng),進(jin)(jin)(jin)行逆流(liu)烘干,物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)中(zhong)層(ceng)不斷地被反復揚進(jin)(jin)(jin),呈進(jin)(jin)(jin)兩步退一(yi)步的行進(jin)(jin)(jin)方式,物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)中(zhong)層(ceng)既(ji)充(chong)(chong)分(fen)吸(xi)收(shou)內(nei)(nei)(nei)層(ceng)滾(gun)筒(tong)散發的熱(re)(re)量(liang),又吸(xi)收(shou)中(zhong)層(ceng)滾(gun)筒(tong)的熱(re)(re)量(liang),同時又延(yan)長了干燥(zao)(zao)時間,物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)此達(da)到干燥(zao)(zao)狀(zhuang)態(tai)。物(wu)(wu)(wu)料(liao)(liao)行至(zhi)(zhi)中(zhong)層(ceng)另一(yi)端(duan)而落(luo)入外(wai)層(ceng),物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)外(wai)層(ceng)滾(gun)筒(tong)內(nei)(nei)(nei)呈矩(ju)形(xing)多回(hui)路方式行進(jin)(jin)(jin),達(da)到干燥(zao)(zao)效(xiao)果的物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)熱(re)(re)風作用下(xia)快速行進(jin)(jin)(jin)排出滾(gun)筒(tong),沒有達(da)到干燥(zao)(zao)效(xiao)果的濕(shi)物(wu)(wu)(wu)料(liao)(liao)因自重而不能(neng)快速行進(jin)(jin)(jin),物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)此矩(ju)形(xing)抄板(ban)內(nei)(nei)(nei)進(jin)(jin)(jin)行充(chong)(chong)分(fen)干燥(zao)(zao),由此完(wan)成干燥(zao)(zao)目的。
