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(hong)干機筒(tong)(tong)體(ti)部分(fen)由三個(ge)同軸水平(ping)放置的內、中、外(wai)筒(tong)(tong)套疊組成，這就使(shi)筒(tong)(tong)體(ti)的截面得到充分(fen)的利用。其筒(tong)(tong)體(ti)外(wai)形總長度(du)約(yue)為與之相當的單筒(tong)(tong)的30-35%。從(cong)而(er)大幅度(du)地減少占地面積(ji)(ji)和廠房建筑(zhu)面積(ji)(ji)。

該機的支承裝置，是在(zai)外筒上輪帶與托(tuo)(tuo)輪支承，由電機直接帶動托(tuo)(tuo)輪。通過(guo)托(tuo)(tuo)輪與輪帶摩擦(ca)，使(shi)筒體(ti)轉動。該機總體(ti)結(jie)構緊湊、合理、簡單，為便于磨損件的檢修更換，在(zai)中(zhong)間設計成軸向剖(pou)分(fen)式(shi)，用螺栓(shuan)固定(ding)連(lian)接。

工(gong)作原理

物(wu)(wu)(wu)料(liao)(liao)(liao)由供料(liao)(liao)(liao)裝置進(jin)入回轉滾筒(tong)(tong)的(de)(de)(de)內層(ceng)(ceng)(ceng),實(shi)現順流(liu)(liu)烘(hong)(hong)干(gan),物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)內層(ceng)(ceng)(ceng)的(de)(de)(de)抄板(ban)下不(bu)斷抄起、散落呈(cheng)螺旋行(xing)進(jin)式(shi)(shi)實(shi)現熱(re)交換，物(wu)(wu)(wu)料(liao)(liao)(liao)移(yi)動至(zhi)內層(ceng)(ceng)(ceng)的(de)(de)(de)另(ling)(ling)一端(duan)進(jin)入中層(ceng)(ceng)(ceng)，進(jin)行(xing)逆流(liu)(liu)烘(hong)(hong)干(gan)，物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)中層(ceng)(ceng)(ceng)不(bu)斷地被(bei)反(fan)復揚進(jin)，呈(cheng)進(jin)兩步退一步的(de)(de)(de)行(xing)進(jin)方式(shi)(shi)，物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)中層(ceng)(ceng)(ceng)既充分(fen)吸(xi)收內層(ceng)(ceng)(ceng)滾筒(tong)(tong)散發的(de)(de)(de)熱(re)量，又(you)吸(xi)收中層(ceng)(ceng)(ceng)滾筒(tong)(tong)的(de)(de)(de)熱(re)量，同時又(you)延長了干(gan)燥時間，物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)此(ci)達(da)到(dao)(dao)干(gan)燥狀態。物(wu)(wu)(wu)料(liao)(liao)(liao)行(xing)至(zhi)中層(ceng)(ceng)(ceng)另(ling)(ling)一端(duan)而(er)落入外層(ceng)(ceng)(ceng)，物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)外層(ceng)(ceng)(ceng)滾筒(tong)(tong)內呈(cheng)矩(ju)(ju)形(xing)多(duo)回路方式(shi)(shi)行(xing)進(jin)，達(da)到(dao)(dao)干(gan)燥效果的(de)(de)(de)物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)熱(re)風作用下快速(su)行(xing)進(jin)排(pai)出滾筒(tong)(tong)，沒有達(da)到(dao)(dao)干(gan)燥效果的(de)(de)(de)濕物(wu)(wu)(wu)料(liao)(liao)(liao)因自重(zhong)而(er)不(bu)能(neng)快速(su)行(xing)進(jin)，物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)此(ci)矩(ju)(ju)形(xing)抄板(ban)內進(jin)行(xing)充分(fen)干(gan)燥，由此(ci)完成干(gan)燥目的(de)(de)(de)。
