產品結構
大型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(bu)分(fen)由三(san)個同軸水平(ping)放(fang)置的內、中、外(wai)筒(tong)套疊(die)組(zu)成,這就使(shi)筒(tong)體的截面得到充分(fen)的利用。其筒(tong)體外(wai)形總(zong)長度約(yue)為與之相當的單(dan)筒(tong)的30-35%。從(cong)而(er)大幅度地減(jian)少占地面積和廠房(fang)建筑(zhu)面積。
該(gai)機的(de)支(zhi)承裝置,是在外筒(tong)上輪(lun)帶與托(tuo)輪(lun)支(zhi)承,由電機直接帶動托(tuo)輪(lun)。通過托(tuo)輪(lun)與輪(lun)帶摩擦(ca),使筒(tong)體轉動。該(gai)機總(zong)體結構緊(jin)湊(cou)、合理、簡單,為便于磨損件的(de)檢修更換,在中(zhong)間設(she)計成軸向剖分(fen)式,用螺栓固定連接。
工作原理
物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)由(you)供料(liao)(liao)(liao)(liao)裝(zhuang)置進(jin)(jin)入(ru)回(hui)轉滾(gun)(gun)筒(tong)(tong)(tong)的(de)(de)內(nei)(nei)(nei)層(ceng)(ceng),實現順流烘干(gan)(gan)(gan),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)(zai)內(nei)(nei)(nei)層(ceng)(ceng)的(de)(de)抄(chao)板(ban)下不(bu)斷抄(chao)起、散落呈(cheng)螺(luo)旋(xuan)行(xing)進(jin)(jin)式實現熱(re)交換,物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)移(yi)動(dong)至(zhi)內(nei)(nei)(nei)層(ceng)(ceng)的(de)(de)另一端進(jin)(jin)入(ru)中(zhong)層(ceng)(ceng),進(jin)(jin)行(xing)逆流烘干(gan)(gan)(gan),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)(zai)中(zhong)層(ceng)(ceng)不(bu)斷地(di)被反復(fu)揚進(jin)(jin),呈(cheng)進(jin)(jin)兩步退一步的(de)(de)行(xing)進(jin)(jin)方式,物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)(zai)中(zhong)層(ceng)(ceng)既充(chong)分吸收內(nei)(nei)(nei)層(ceng)(ceng)滾(gun)(gun)筒(tong)(tong)(tong)散發的(de)(de)熱(re)量,又吸收中(zhong)層(ceng)(ceng)滾(gun)(gun)筒(tong)(tong)(tong)的(de)(de)熱(re)量,同(tong)時(shi)(shi)又延長了干(gan)(gan)(gan)燥(zao)(zao)(zao)時(shi)(shi)間,物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)(zai)此達(da)到干(gan)(gan)(gan)燥(zao)(zao)(zao)狀態。物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)行(xing)至(zhi)中(zhong)層(ceng)(ceng)另一端而落入(ru)外層(ceng)(ceng),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)(zai)外層(ceng)(ceng)滾(gun)(gun)筒(tong)(tong)(tong)內(nei)(nei)(nei)呈(cheng)矩(ju)形多回(hui)路(lu)方式行(xing)進(jin)(jin),達(da)到干(gan)(gan)(gan)燥(zao)(zao)(zao)效果(guo)(guo)的(de)(de)物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)(zai)熱(re)風作用下快速(su)行(xing)進(jin)(jin)排(pai)出滾(gun)(gun)筒(tong)(tong)(tong),沒(mei)有達(da)到干(gan)(gan)(gan)燥(zao)(zao)(zao)效果(guo)(guo)的(de)(de)濕物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)因自重而不(bu)能(neng)快速(su)行(xing)進(jin)(jin),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)(zai)此矩(ju)形抄(chao)板(ban)內(nei)(nei)(nei)進(jin)(jin)行(xing)充(chong)分干(gan)(gan)(gan)燥(zao)(zao)(zao),由(you)此完成(cheng)干(gan)(gan)(gan)燥(zao)(zao)(zao)目的(de)(de)。
