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。
烘干機(ji)筒體(ti)部分由三個同軸(zhou)水(shui)平(ping)放置的內(nei)、中、外(wai)筒套疊(die)組成,這(zhe)就使(shi)筒體(ti)的截面(mian)(mian)得到充分的利用。其筒體(ti)外(wai)形總長(chang)度約為(wei)與之(zhi)相當的單筒的30-35%。從而大幅(fu)度地減少占(zhan)地面(mian)(mian)積和廠(chang)房建筑(zhu)面(mian)(mian)積。
該機(ji)的(de)支承裝置,是在(zai)外筒上輪(lun)帶(dai)與托(tuo)輪(lun)支承,由電機(ji)直接帶(dai)動(dong)托(tuo)輪(lun)。通過(guo)托(tuo)輪(lun)與輪(lun)帶(dai)摩擦(ca),使筒體轉動(dong)。該機(ji)總體結(jie)構緊湊、合(he)理、簡單,為便(bian)于(yu)磨損(sun)件(jian)的(de)檢修更換,在(zai)中間設計(ji)成(cheng)軸向剖分式,用螺(luo)栓固(gu)定連(lian)接。
工作原(yuan)理
物(wu)(wu)(wu)(wu)料(liao)(liao)由供料(liao)(liao)裝置進(jin)(jin)(jin)入回轉滾(gun)(gun)(gun)筒(tong)(tong)的(de)(de)內(nei)層(ceng)(ceng)(ceng),實(shi)現順流(liu)烘干,物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)內(nei)層(ceng)(ceng)(ceng)的(de)(de)抄(chao)板下(xia)不斷抄(chao)起、散(san)落呈(cheng)螺旋行(xing)進(jin)(jin)(jin)式實(shi)現熱(re)交換(huan),物(wu)(wu)(wu)(wu)料(liao)(liao)移動至(zhi)內(nei)層(ceng)(ceng)(ceng)的(de)(de)另(ling)一端進(jin)(jin)(jin)入中層(ceng)(ceng)(ceng),進(jin)(jin)(jin)行(xing)逆流(liu)烘干,物(wu)(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(cheng)進(jin)(jin)(jin)兩步(bu)退一步(bu)的(de)(de)行(xing)進(jin)(jin)(jin)方式,物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)中層(ceng)(ceng)(ceng)既充分吸收內(nei)層(ceng)(ceng)(ceng)滾(gun)(gun)(gun)筒(tong)(tong)散(san)發(fa)的(de)(de)熱(re)量,又(you)吸收中層(ceng)(ceng)(ceng)滾(gun)(gun)(gun)筒(tong)(tong)的(de)(de)熱(re)量,同(tong)時(shi)又(you)延長了(le)干燥(zao)(zao)時(shi)間,物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)此達到(dao)干燥(zao)(zao)狀(zhuang)態。物(wu)(wu)(wu)(wu)料(liao)(liao)行(xing)至(zhi)中層(ceng)(ceng)(ceng)另(ling)一端而落入外(wai)層(ceng)(ceng)(ceng),物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)外(wai)層(ceng)(ceng)(ceng)滾(gun)(gun)(gun)筒(tong)(tong)內(nei)呈(cheng)矩形多回路方式行(xing)進(jin)(jin)(jin),達到(dao)干燥(zao)(zao)效果的(de)(de)物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)熱(re)風作用下(xia)快(kuai)速行(xing)進(jin)(jin)(jin)排出滾(gun)(gun)(gun)筒(tong)(tong),沒有達到(dao)干燥(zao)(zao)效果的(de)(de)濕物(wu)(wu)(wu)(wu)料(liao)(liao)因自(zi)重而不能快(kuai)速行(xing)進(jin)(jin)(jin),物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)此矩形抄(chao)板內(nei)進(jin)(jin)(jin)行(xing)充分干燥(zao)(zao),由此完成干燥(zao)(zao)目的(de)(de)。
