產(chan)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(hong)干機(ji)筒(tong)(tong)體部分由三個同軸水(shui)平放置的(de)內、中、外筒(tong)(tong)套疊組(zu)成(cheng),這就使(shi)筒(tong)(tong)體的(de)截(jie)面(mian)得(de)到充(chong)分的(de)利(li)用。其(qi)筒(tong)(tong)體外形總長度(du)約為與之相當(dang)的(de)單(dan)筒(tong)(tong)的(de)30-35%。從(cong)而大(da)幅度(du)地減少占地面(mian)積和廠(chang)房建筑面(mian)積。
該機(ji)的支(zhi)承(cheng)裝(zhuang)置,是在外筒(tong)上輪(lun)帶(dai)與托輪(lun)支(zhi)承(cheng),由電機(ji)直(zhi)接帶(dai)動(dong)托輪(lun)。通過托輪(lun)與輪(lun)帶(dai)摩擦,使筒(tong)體(ti)轉動(dong)。該機(ji)總體(ti)結構緊湊、合(he)理、簡單,為便于磨損件的檢修更換,在中間設計成軸向剖分式(shi),用螺栓固定連接。
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(zhuan)滾(gun)(gun)筒(tong)的(de)(de)(de)(de)(de)內(nei)(nei)層(ceng)(ceng)(ceng),實現(xian)順(shun)流烘干(gan),物(wu)(wu)(wu)料(liao)(liao)在(zai)內(nei)(nei)層(ceng)(ceng)(ceng)的(de)(de)(de)(de)(de)抄(chao)板下(xia)不斷抄(chao)起、散落呈螺旋行(xing)進(jin)(jin)(jin)式(shi)(shi)實現(xian)熱(re)(re)交換(huan),物(wu)(wu)(wu)料(liao)(liao)移動(dong)至(zhi)內(nei)(nei)層(ceng)(ceng)(ceng)的(de)(de)(de)(de)(de)另一端(duan)進(jin)(jin)(jin)入中層(ceng)(ceng)(ceng),進(jin)(jin)(jin)行(xing)逆流烘干(gan),物(wu)(wu)(wu)料(liao)(liao)在(zai)中層(ceng)(ceng)(ceng)不斷地被反復揚(yang)進(jin)(jin)(jin),呈進(jin)(jin)(jin)兩(liang)步退一步的(de)(de)(de)(de)(de)行(xing)進(jin)(jin)(jin)方(fang)式(shi)(shi),物(wu)(wu)(wu)料(liao)(liao)在(zai)中層(ceng)(ceng)(ceng)既充(chong)分吸(xi)(xi)收內(nei)(nei)層(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)散發的(de)(de)(de)(de)(de)熱(re)(re)量,又(you)吸(xi)(xi)收中層(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)的(de)(de)(de)(de)(de)熱(re)(re)量,同時又(you)延長了干(gan)燥(zao)(zao)(zao)時間,物(wu)(wu)(wu)料(liao)(liao)在(zai)此(ci)達到干(gan)燥(zao)(zao)(zao)狀態(tai)。物(wu)(wu)(wu)料(liao)(liao)行(xing)至(zhi)中層(ceng)(ceng)(ceng)另一端(duan)而(er)落入外層(ceng)(ceng)(ceng),物(wu)(wu)(wu)料(liao)(liao)在(zai)外層(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)內(nei)(nei)呈矩形(xing)多回(hui)路(lu)方(fang)式(shi)(shi)行(xing)進(jin)(jin)(jin),達到干(gan)燥(zao)(zao)(zao)效果(guo)的(de)(de)(de)(de)(de)物(wu)(wu)(wu)料(liao)(liao)在(zai)熱(re)(re)風作用下(xia)快速行(xing)進(jin)(jin)(jin)排出(chu)滾(gun)(gun)筒(tong),沒有達到干(gan)燥(zao)(zao)(zao)效果(guo)的(de)(de)(de)(de)(de)濕物(wu)(wu)(wu)料(liao)(liao)因自重而(er)不能快速行(xing)進(jin)(jin)(jin),物(wu)(wu)(wu)料(liao)(liao)在(zai)此(ci)矩形(xing)抄(chao)板內(nei)(nei)進(jin)(jin)(jin)行(xing)充(chong)分干(gan)燥(zao)(zao)(zao),由此(ci)完成干(gan)燥(zao)(zao)(zao)目(mu)的(de)(de)(de)(de)(de)。
