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(hong)干機筒體(ti)部(bu)分由三個(ge)同軸水(shui)平(ping)放置的(de)內、中(zhong)、外筒套疊(die)組(zu)成,這就使筒體(ti)的(de)截面(mian)得到充(chong)分的(de)利(li)用。其(qi)筒體(ti)外形總長度約為與之相當的(de)單筒的(de)30-35%。從而大幅度地減少占地面(mian)積(ji)和廠(chang)房(fang)建(jian)筑面(mian)積(ji)。
該機(ji)(ji)的支(zhi)承裝置,是在(zai)外筒(tong)上輪(lun)(lun)帶(dai)與托輪(lun)(lun)支(zhi)承,由電(dian)機(ji)(ji)直接帶(dai)動托輪(lun)(lun)。通(tong)過托輪(lun)(lun)與輪(lun)(lun)帶(dai)摩擦(ca),使筒(tong)體轉動。該機(ji)(ji)總體結構(gou)緊(jin)湊、合(he)理、簡單,為便于磨損件的檢修更換,在(zai)中間設計成軸向剖分式,用螺栓固(gu)定(ding)連(lian)接。
工(gong)作(zuo)原理
物(wu)(wu)(wu)(wu)料(liao)(liao)由(you)供料(liao)(liao)裝置進(jin)(jin)(jin)入回(hui)轉滾(gun)筒(tong)的(de)內(nei)(nei)層(ceng)(ceng)(ceng)(ceng),實現順(shun)流烘干(gan),物(wu)(wu)(wu)(wu)料(liao)(liao)在內(nei)(nei)層(ceng)(ceng)(ceng)(ceng)的(de)抄(chao)板(ban)下不(bu)斷抄(chao)起(qi)、散落(luo)呈螺旋行(xing)進(jin)(jin)(jin)式實現熱(re)交(jiao)換,物(wu)(wu)(wu)(wu)料(liao)(liao)移動至(zhi)(zhi)內(nei)(nei)層(ceng)(ceng)(ceng)(ceng)的(de)另一(yi)端進(jin)(jin)(jin)入中(zhong)層(ceng)(ceng)(ceng)(ceng),進(jin)(jin)(jin)行(xing)逆流烘干(gan),物(wu)(wu)(wu)(wu)料(liao)(liao)在中(zhong)層(ceng)(ceng)(ceng)(ceng)不(bu)斷地被反復(fu)揚進(jin)(jin)(jin),呈進(jin)(jin)(jin)兩步(bu)退一(yi)步(bu)的(de)行(xing)進(jin)(jin)(jin)方式,物(wu)(wu)(wu)(wu)料(liao)(liao)在中(zhong)層(ceng)(ceng)(ceng)(ceng)既充分吸(xi)(xi)收內(nei)(nei)層(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)散發的(de)熱(re)量(liang),又吸(xi)(xi)收中(zhong)層(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)的(de)熱(re)量(liang),同時(shi)又延(yan)長(chang)了干(gan)燥時(shi)間,物(wu)(wu)(wu)(wu)料(liao)(liao)在此達到(dao)(dao)干(gan)燥狀(zhuang)態(tai)。物(wu)(wu)(wu)(wu)料(liao)(liao)行(xing)至(zhi)(zhi)中(zhong)層(ceng)(ceng)(ceng)(ceng)另一(yi)端而(er)(er)落(luo)入外層(ceng)(ceng)(ceng)(ceng),物(wu)(wu)(wu)(wu)料(liao)(liao)在外層(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)內(nei)(nei)呈矩(ju)形多回(hui)路(lu)方式行(xing)進(jin)(jin)(jin),達到(dao)(dao)干(gan)燥效果的(de)物(wu)(wu)(wu)(wu)料(liao)(liao)在熱(re)風(feng)作用下快速(su)行(xing)進(jin)(jin)(jin)排(pai)出滾(gun)筒(tong),沒有達到(dao)(dao)干(gan)燥效果的(de)濕物(wu)(wu)(wu)(wu)料(liao)(liao)因自重而(er)(er)不(bu)能(neng)快速(su)行(xing)進(jin)(jin)(jin),物(wu)(wu)(wu)(wu)料(liao)(liao)在此矩(ju)形抄(chao)板(ban)內(nei)(nei)進(jin)(jin)(jin)行(xing)充分干(gan)燥,由(you)此完成(cheng)干(gan)燥目的(de)。
