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)(tong)體部分由三個同軸水平放置的(de)內、中、外筒(tong)(tong)套疊組(zu)成,這就使(shi)筒(tong)(tong)體的(de)截面(mian)得到充分的(de)利用(yong)。其筒(tong)(tong)體外形總長度約為與之相當的(de)單筒(tong)(tong)的(de)30-35%。從而大幅度地減(jian)少(shao)占(zhan)地面(mian)積和廠房建(jian)筑(zhu)面(mian)積。
該機的(de)支承裝(zhuang)置,是在(zai)外筒(tong)上輪(lun)(lun)帶(dai)與托輪(lun)(lun)支承,由電機直接帶(dai)動托輪(lun)(lun)。通(tong)過托輪(lun)(lun)與輪(lun)(lun)帶(dai)摩擦,使筒(tong)體轉動。該機總(zong)體結構緊湊(cou)、合理(li)、簡單(dan),為(wei)便于(yu)磨損件的(de)檢修更(geng)換,在(zai)中間設計成軸(zhou)向剖分(fen)式,用螺栓固定(ding)連接。
工作原理
物料(liao)由(you)供(gong)料(liao)裝(zhuang)置進(jin)入(ru)(ru)回(hui)(hui)轉(zhuan)滾(gun)筒的(de)(de)內(nei)層(ceng)(ceng)(ceng)(ceng),實現順流烘干(gan),物料(liao)在(zai)(zai)內(nei)層(ceng)(ceng)(ceng)(ceng)的(de)(de)抄(chao)板下不斷抄(chao)起、散(san)落呈(cheng)(cheng)螺旋行(xing)(xing)(xing)(xing)進(jin)式實現熱(re)交(jiao)換,物料(liao)移(yi)動至(zhi)(zhi)內(nei)層(ceng)(ceng)(ceng)(ceng)的(de)(de)另一端進(jin)入(ru)(ru)中層(ceng)(ceng)(ceng)(ceng),進(jin)行(xing)(xing)(xing)(xing)逆流烘干(gan),物料(liao)在(zai)(zai)中層(ceng)(ceng)(ceng)(ceng)不斷地被反復揚(yang)進(jin),呈(cheng)(cheng)進(jin)兩(liang)步(bu)退一步(bu)的(de)(de)行(xing)(xing)(xing)(xing)進(jin)方式,物料(liao)在(zai)(zai)中層(ceng)(ceng)(ceng)(ceng)既充分吸收內(nei)層(ceng)(ceng)(ceng)(ceng)滾(gun)筒散(san)發的(de)(de)熱(re)量,又(you)吸收中層(ceng)(ceng)(ceng)(ceng)滾(gun)筒的(de)(de)熱(re)量,同(tong)時(shi)又(you)延長了干(gan)燥(zao)(zao)(zao)時(shi)間,物料(liao)在(zai)(zai)此達到(dao)干(gan)燥(zao)(zao)(zao)狀態。物料(liao)行(xing)(xing)(xing)(xing)至(zhi)(zhi)中層(ceng)(ceng)(ceng)(ceng)另一端而(er)落入(ru)(ru)外層(ceng)(ceng)(ceng)(ceng),物料(liao)在(zai)(zai)外層(ceng)(ceng)(ceng)(ceng)滾(gun)筒內(nei)呈(cheng)(cheng)矩形多回(hui)(hui)路(lu)方式行(xing)(xing)(xing)(xing)進(jin),達到(dao)干(gan)燥(zao)(zao)(zao)效果(guo)(guo)的(de)(de)物料(liao)在(zai)(zai)熱(re)風作用下快速行(xing)(xing)(xing)(xing)進(jin)排出滾(gun)筒,沒有(you)達到(dao)干(gan)燥(zao)(zao)(zao)效果(guo)(guo)的(de)(de)濕物料(liao)因自(zi)重而(er)不能快速行(xing)(xing)(xing)(xing)進(jin),物料(liao)在(zai)(zai)此矩形抄(chao)板內(nei)進(jin)行(xing)(xing)(xing)(xing)充分干(gan)燥(zao)(zao)(zao),由(you)此完成干(gan)燥(zao)(zao)(zao)目的(de)(de)。
