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(gan)機筒(tong)(tong)(tong)體部(bu)分由三個同軸水平放(fang)置的(de)內、中、外(wai)(wai)筒(tong)(tong)(tong)套疊組成,這就(jiu)使筒(tong)(tong)(tong)體的(de)截面(mian)(mian)得到充分的(de)利用。其筒(tong)(tong)(tong)體外(wai)(wai)形總長度約為與之相當的(de)單筒(tong)(tong)(tong)的(de)30-35%。從而大(da)幅度地減少(shao)占地面(mian)(mian)積和廠房建筑面(mian)(mian)積。
該機(ji)的(de)支承裝置,是在(zai)(zai)外筒上輪(lun)(lun)帶(dai)(dai)與托輪(lun)(lun)支承,由電機(ji)直接帶(dai)(dai)動托輪(lun)(lun)。通過托輪(lun)(lun)與輪(lun)(lun)帶(dai)(dai)摩擦,使筒體轉(zhuan)動。該機(ji)總體結構緊湊(cou)、合理、簡單,為便于磨損(sun)件的(de)檢修更換,在(zai)(zai)中間設計成軸向剖分式,用螺栓固定連接。
工作原理
物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)由(you)供(gong)料(liao)(liao)(liao)(liao)裝(zhuang)置進(jin)(jin)(jin)(jin)入(ru)回(hui)轉滾筒(tong)(tong)的(de)(de)內層(ceng)(ceng),實現順流(liu)烘干(gan),物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在內層(ceng)(ceng)的(de)(de)抄板下(xia)不斷抄起(qi)、散落(luo)呈(cheng)螺旋行(xing)進(jin)(jin)(jin)(jin)式(shi)實現熱(re)交(jiao)換,物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)移(yi)動至(zhi)內層(ceng)(ceng)的(de)(de)另一(yi)(yi)端(duan)進(jin)(jin)(jin)(jin)入(ru)中(zhong)(zhong)層(ceng)(ceng),進(jin)(jin)(jin)(jin)行(xing)逆流(liu)烘干(gan),物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在中(zhong)(zhong)層(ceng)(ceng)不斷地被反復揚進(jin)(jin)(jin)(jin),呈(cheng)進(jin)(jin)(jin)(jin)兩步退一(yi)(yi)步的(de)(de)行(xing)進(jin)(jin)(jin)(jin)方式(shi),物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在中(zhong)(zhong)層(ceng)(ceng)既充分吸(xi)收內層(ceng)(ceng)滾筒(tong)(tong)散發的(de)(de)熱(re)量,又(you)吸(xi)收中(zhong)(zhong)層(ceng)(ceng)滾筒(tong)(tong)的(de)(de)熱(re)量,同(tong)時又(you)延長(chang)了干(gan)燥(zao)時間(jian),物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在此達(da)到干(gan)燥(zao)狀態。物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)行(xing)至(zhi)中(zhong)(zhong)層(ceng)(ceng)另一(yi)(yi)端(duan)而落(luo)入(ru)外(wai)層(ceng)(ceng),物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在外(wai)層(ceng)(ceng)滾筒(tong)(tong)內呈(cheng)矩(ju)形多回(hui)路方式(shi)行(xing)進(jin)(jin)(jin)(jin),達(da)到干(gan)燥(zao)效果的(de)(de)物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在熱(re)風作用下(xia)快速(su)行(xing)進(jin)(jin)(jin)(jin)排出滾筒(tong)(tong),沒有達(da)到干(gan)燥(zao)效果的(de)(de)濕(shi)物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)因(yin)自重(zhong)而不能(neng)快速(su)行(xing)進(jin)(jin)(jin)(jin),物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在此矩(ju)形抄板內進(jin)(jin)(jin)(jin)行(xing)充分干(gan)燥(zao),由(you)此完(wan)成干(gan)燥(zao)目的(de)(de)。
