產品結構
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)部分(fen)由三個同軸水平放置的(de)內、中(zhong)、外(wai)筒(tong)套疊組成，這就使筒(tong)體(ti)(ti)的(de)截面得到充分(fen)的(de)利用。其筒(tong)體(ti)(ti)外(wai)形總長(chang)度(du)約為與之相當(dang)的(de)單筒(tong)的(de)30-35%。從而大幅度(du)地(di)減少占地(di)面積和廠(chang)房建(jian)筑面積。
該機的(de)支承裝置，是在(zai)外筒(tong)上(shang)輪帶(dai)與托(tuo)輪支承，由電(dian)機直接帶(dai)動(dong)托(tuo)輪。通過托(tuo)輪與輪帶(dai)摩擦，使筒(tong)體轉動(dong)。該機總體結構緊湊、合理、簡(jian)單(dan)，為便于磨損件(jian)的(de)檢修更換，在(zai)中間設計(ji)成軸向(xiang)剖分式，用螺栓(shuan)固定連接。
工(gong)作原理(li)
物(wu)料(liao)(liao)(liao)由供料(liao)(liao)(liao)裝置進入回轉滾筒(tong)(tong)(tong)(tong)的(de)(de)內層(ceng)(ceng)(ceng)(ceng),實(shi)現順流(liu)烘干(gan)(gan),物(wu)料(liao)(liao)(liao)在(zai)(zai)內層(ceng)(ceng)(ceng)(ceng)的(de)(de)抄板(ban)下(xia)不(bu)(bu)(bu)斷(duan)抄起、散(san)落(luo)呈螺旋行(xing)進式(shi)實(shi)現熱交換，物(wu)料(liao)(liao)(liao)移動至內層(ceng)(ceng)(ceng)(ceng)的(de)(de)另一(yi)端進入中(zhong)層(ceng)(ceng)(ceng)(ceng)，進行(xing)逆流(liu)烘干(gan)(gan)，物(wu)料(liao)(liao)(liao)在(zai)(zai)中(zhong)層(ceng)(ceng)(ceng)(ceng)不(bu)(bu)(bu)斷(duan)地被反復揚進，呈進兩(liang)步(bu)退一(yi)步(bu)的(de)(de)行(xing)進方式(shi)，物(wu)料(liao)(liao)(liao)在(zai)(zai)中(zhong)層(ceng)(ceng)(ceng)(ceng)既(ji)充分吸收內層(ceng)(ceng)(ceng)(ceng)滾筒(tong)(tong)(tong)(tong)散(san)發的(de)(de)熱量，又(you)吸收中(zhong)層(ceng)(ceng)(ceng)(ceng)滾筒(tong)(tong)(tong)(tong)的(de)(de)熱量，同時又(you)延(yan)長了干(gan)(gan)燥(zao)時間，物(wu)料(liao)(liao)(liao)在(zai)(zai)此(ci)(ci)達到干(gan)(gan)燥(zao)狀(zhuang)態。物(wu)料(liao)(liao)(liao)行(xing)至中(zhong)層(ceng)(ceng)(ceng)(ceng)另一(yi)端而(er)落(luo)入外層(ceng)(ceng)(ceng)(ceng)，物(wu)料(liao)(liao)(liao)在(zai)(zai)外層(ceng)(ceng)(ceng)(ceng)滾筒(tong)(tong)(tong)(tong)內呈矩(ju)形(xing)多回路方式(shi)行(xing)進，達到干(gan)(gan)燥(zao)效果(guo)的(de)(de)物(wu)料(liao)(liao)(liao)在(zai)(zai)熱風(feng)作用(yong)下(xia)快(kuai)速行(xing)進排出滾筒(tong)(tong)(tong)(tong)，沒有達到干(gan)(gan)燥(zao)效果(guo)的(de)(de)濕物(wu)料(liao)(liao)(liao)因自重(zhong)而(er)不(bu)(bu)(bu)能快(kuai)速行(xing)進，物(wu)料(liao)(liao)(liao)在(zai)(zai)此(ci)(ci)矩(ju)形(xing)抄板(ban)內進行(xing)充分干(gan)(gan)燥(zao)，由此(ci)(ci)完成干(gan)(gan)燥(zao)目的(de)(de)。
