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。
烘干機筒體部分由三個同(tong)軸水平放置(zhi)的內、中、外筒套疊組(zu)成,這就使筒體的截面得到充分的利用。其(qi)筒體外形(xing)總(zong)長度約為與(yu)之相當的單筒的30-35%。從而(er)大幅(fu)度地減(jian)少占地面積(ji)和廠房建筑面積(ji)。
該機的支(zhi)承裝置,是在外筒上輪帶與(yu)(yu)托(tuo)輪支(zhi)承,由(you)電(dian)機直接帶動(dong)托(tuo)輪。通過托(tuo)輪與(yu)(yu)輪帶摩擦(ca),使(shi)筒體(ti)轉動(dong)。該機總體(ti)結構緊湊、合理、簡(jian)單,為便于磨(mo)損件(jian)的檢修(xiu)更(geng)換(huan),在中間設計(ji)成軸向剖分式,用(yong)螺栓固定(ding)連接。
工(gong)作(zuo)原理
物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)由供(gong)料(liao)(liao)(liao)(liao)(liao)裝置(zhi)進(jin)入(ru)回轉滾筒的(de)(de)內(nei)層(ceng)(ceng)(ceng)(ceng),實現順流烘干(gan),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)(zai)內(nei)層(ceng)(ceng)(ceng)(ceng)的(de)(de)抄(chao)(chao)板下不(bu)斷(duan)抄(chao)(chao)起、散落呈(cheng)螺旋行(xing)進(jin)式(shi)實現熱交換,物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)移動至內(nei)層(ceng)(ceng)(ceng)(ceng)的(de)(de)另一端進(jin)入(ru)中(zhong)層(ceng)(ceng)(ceng)(ceng),進(jin)行(xing)逆(ni)流烘干(gan),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)(zai)中(zhong)層(ceng)(ceng)(ceng)(ceng)不(bu)斷(duan)地(di)被(bei)反復揚進(jin),呈(cheng)進(jin)兩步(bu)退一步(bu)的(de)(de)行(xing)進(jin)方式(shi),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)(zai)中(zhong)層(ceng)(ceng)(ceng)(ceng)既充分吸收內(nei)層(ceng)(ceng)(ceng)(ceng)滾筒散發的(de)(de)熱量,又吸收中(zhong)層(ceng)(ceng)(ceng)(ceng)滾筒的(de)(de)熱量,同時又延長了干(gan)燥(zao)時間,物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)(zai)此達到(dao)(dao)干(gan)燥(zao)狀(zhuang)態。物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)行(xing)至中(zhong)層(ceng)(ceng)(ceng)(ceng)另一端而落入(ru)外層(ceng)(ceng)(ceng)(ceng),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)(zai)外層(ceng)(ceng)(ceng)(ceng)滾筒內(nei)呈(cheng)矩形多回路方式(shi)行(xing)進(jin),達到(dao)(dao)干(gan)燥(zao)效(xiao)果(guo)的(de)(de)物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)(zai)熱風(feng)作用下快速(su)行(xing)進(jin)排(pai)出滾筒,沒有(you)達到(dao)(dao)干(gan)燥(zao)效(xiao)果(guo)的(de)(de)濕(shi)物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)因自重而不(bu)能快速(su)行(xing)進(jin),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)(zai)此矩形抄(chao)(chao)板內(nei)進(jin)行(xing)充分干(gan)燥(zao),由此完成干(gan)燥(zao)目的(de)(de)。
