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(ti)(ti)部(bu)分(fen)由三個同軸水(shui)平放置的內、中、外(wai)(wai)筒(tong)套(tao)疊組成,這(zhe)就使(shi)筒(tong)體(ti)(ti)的截(jie)面得(de)到充分(fen)的利用。其筒(tong)體(ti)(ti)外(wai)(wai)形(xing)總(zong)長度約為與之相當的單筒(tong)的30-35%。從而大(da)幅度地(di)(di)減(jian)少(shao)占地(di)(di)面積和廠房建筑(zhu)面積。
該機(ji)的(de)支(zhi)承裝置,是在外筒(tong)上輪帶與托輪支(zhi)承,由電機(ji)直接(jie)帶動托輪。通過托輪與輪帶摩擦(ca),使筒(tong)體轉(zhuan)動。該機(ji)總體結構緊(jin)湊、合理、簡單,為便于磨損件的(de)檢修更換,在中(zhong)間設計成軸向(xiang)剖分(fen)式,用螺(luo)栓(shuan)固(gu)定連接(jie)。
工作原理(li)
物(wu)(wu)(wu)料(liao)(liao)(liao)由(you)供料(liao)(liao)(liao)裝置進(jin)(jin)(jin)入(ru)回(hui)轉滾筒的(de)(de)(de)內(nei)層(ceng)(ceng)(ceng)(ceng),實現順流烘干(gan)(gan),物(wu)(wu)(wu)料(liao)(liao)(liao)在內(nei)層(ceng)(ceng)(ceng)(ceng)的(de)(de)(de)抄板下(xia)不(bu)斷抄起(qi)、散落呈(cheng)(cheng)螺旋(xuan)行(xing)進(jin)(jin)(jin)式(shi)(shi)實現熱(re)交(jiao)換,物(wu)(wu)(wu)料(liao)(liao)(liao)移動(dong)至(zhi)內(nei)層(ceng)(ceng)(ceng)(ceng)的(de)(de)(de)另(ling)一端進(jin)(jin)(jin)入(ru)中(zhong)層(ceng)(ceng)(ceng)(ceng),進(jin)(jin)(jin)行(xing)逆流烘干(gan)(gan),物(wu)(wu)(wu)料(liao)(liao)(liao)在中(zhong)層(ceng)(ceng)(ceng)(ceng)不(bu)斷地被反復揚進(jin)(jin)(jin),呈(cheng)(cheng)進(jin)(jin)(jin)兩步(bu)退一步(bu)的(de)(de)(de)行(xing)進(jin)(jin)(jin)方式(shi)(shi),物(wu)(wu)(wu)料(liao)(liao)(liao)在中(zhong)層(ceng)(ceng)(ceng)(ceng)既充分吸(xi)(xi)收內(nei)層(ceng)(ceng)(ceng)(ceng)滾筒散發的(de)(de)(de)熱(re)量,又吸(xi)(xi)收中(zhong)層(ceng)(ceng)(ceng)(ceng)滾筒的(de)(de)(de)熱(re)量,同時(shi)又延長了干(gan)(gan)燥(zao)時(shi)間(jian),物(wu)(wu)(wu)料(liao)(liao)(liao)在此(ci)達到干(gan)(gan)燥(zao)狀態(tai)。物(wu)(wu)(wu)料(liao)(liao)(liao)行(xing)至(zhi)中(zhong)層(ceng)(ceng)(ceng)(ceng)另(ling)一端而落入(ru)外(wai)層(ceng)(ceng)(ceng)(ceng),物(wu)(wu)(wu)料(liao)(liao)(liao)在外(wai)層(ceng)(ceng)(ceng)(ceng)滾筒內(nei)呈(cheng)(cheng)矩形(xing)多回(hui)路方式(shi)(shi)行(xing)進(jin)(jin)(jin),達到干(gan)(gan)燥(zao)效(xiao)果(guo)的(de)(de)(de)物(wu)(wu)(wu)料(liao)(liao)(liao)在熱(re)風作用下(xia)快速行(xing)進(jin)(jin)(jin)排出滾筒,沒有達到干(gan)(gan)燥(zao)效(xiao)果(guo)的(de)(de)(de)濕(shi)物(wu)(wu)(wu)料(liao)(liao)(liao)因(yin)自重(zhong)而不(bu)能快速行(xing)進(jin)(jin)(jin),物(wu)(wu)(wu)料(liao)(liao)(liao)在此(ci)矩形(xing)抄板內(nei)進(jin)(jin)(jin)行(xing)充分干(gan)(gan)燥(zao),由(you)此(ci)完成干(gan)(gan)燥(zao)目的(de)(de)(de)。
