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)由三個同軸水平(ping)放置的(de)內、中、外筒(tong)套疊組成,這(zhe)就使筒(tong)體的(de)截面得到充分(fen)的(de)利(li)用。其筒(tong)體外形(xing)總(zong)長度約為與(yu)之相當的(de)單筒(tong)的(de)30-35%。從而大幅度地(di)減少占(zhan)地(di)面積(ji)和廠房建(jian)筑面積(ji)。
該機的支(zhi)承裝置,是在外筒(tong)上輪(lun)(lun)(lun)帶(dai)與(yu)托(tuo)輪(lun)(lun)(lun)支(zhi)承,由電機直接(jie)帶(dai)動(dong)托(tuo)輪(lun)(lun)(lun)。通過托(tuo)輪(lun)(lun)(lun)與(yu)輪(lun)(lun)(lun)帶(dai)摩擦,使筒(tong)體(ti)轉動(dong)。該機總(zong)體(ti)結構(gou)緊湊、合理、簡單,為便于磨(mo)損件的檢修更(geng)換,在中間設計成軸向剖分式,用螺(luo)栓固定連接(jie)。
工作原理
物(wu)料(liao)(liao)(liao)(liao)由供料(liao)(liao)(liao)(liao)裝置進(jin)入回轉滾(gun)(gun)(gun)筒(tong)(tong)的(de)內(nei)層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng),實(shi)現順流(liu)烘干(gan)(gan),物(wu)料(liao)(liao)(liao)(liao)在內(nei)層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)的(de)抄板(ban)下不(bu)斷抄起、散落(luo)呈(cheng)(cheng)螺旋(xuan)行(xing)進(jin)式(shi)(shi)實(shi)現熱(re)交(jiao)換,物(wu)料(liao)(liao)(liao)(liao)移(yi)動至(zhi)內(nei)層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)的(de)另一(yi)端(duan)進(jin)入中層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng),進(jin)行(xing)逆流(liu)烘干(gan)(gan),物(wu)料(liao)(liao)(liao)(liao)在中層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)不(bu)斷地被反(fan)復揚進(jin),呈(cheng)(cheng)進(jin)兩步退一(yi)步的(de)行(xing)進(jin)方式(shi)(shi),物(wu)料(liao)(liao)(liao)(liao)在中層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)既充(chong)分吸收內(nei)層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)(gun)筒(tong)(tong)散發(fa)的(de)熱(re)量,又吸收中層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)(gun)筒(tong)(tong)的(de)熱(re)量,同時又延(yan)長了干(gan)(gan)燥(zao)(zao)時間,物(wu)料(liao)(liao)(liao)(liao)在此(ci)(ci)達(da)到干(gan)(gan)燥(zao)(zao)狀態(tai)。物(wu)料(liao)(liao)(liao)(liao)行(xing)至(zhi)中層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)另一(yi)端(duan)而落(luo)入外層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng),物(wu)料(liao)(liao)(liao)(liao)在外層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)(gun)筒(tong)(tong)內(nei)呈(cheng)(cheng)矩(ju)形多回路方式(shi)(shi)行(xing)進(jin),達(da)到干(gan)(gan)燥(zao)(zao)效果(guo)(guo)的(de)物(wu)料(liao)(liao)(liao)(liao)在熱(re)風作用下快速(su)行(xing)進(jin)排出滾(gun)(gun)(gun)筒(tong)(tong),沒有達(da)到干(gan)(gan)燥(zao)(zao)效果(guo)(guo)的(de)濕(shi)物(wu)料(liao)(liao)(liao)(liao)因自重而不(bu)能快速(su)行(xing)進(jin),物(wu)料(liao)(liao)(liao)(liao)在此(ci)(ci)矩(ju)形抄板(ban)內(nei)進(jin)行(xing)充(chong)分干(gan)(gan)燥(zao)(zao),由此(ci)(ci)完成干(gan)(gan)燥(zao)(zao)目的(de)。
