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)體部(bu)分由(you)三個同軸(zhou)水平(ping)放(fang)置的(de)(de)內、中、外筒(tong)套疊組成,這就使筒(tong)體的(de)(de)截面(mian)得到充分的(de)(de)利(li)用。其筒(tong)體外形總長度(du)約(yue)為與之相當的(de)(de)單筒(tong)的(de)(de)30-35%。從而大(da)幅度(du)地減少占地面(mian)積(ji)和廠房(fang)建筑面(mian)積(ji)。
該機(ji)的支承(cheng)裝(zhuang)置,是在外筒(tong)上(shang)輪(lun)帶與托(tuo)(tuo)輪(lun)支承(cheng),由電(dian)機(ji)直(zhi)接帶動(dong)托(tuo)(tuo)輪(lun)。通過托(tuo)(tuo)輪(lun)與輪(lun)帶摩(mo)擦(ca),使筒(tong)體(ti)(ti)轉(zhuan)動(dong)。該機(ji)總(zong)體(ti)(ti)結(jie)構緊湊、合理、簡(jian)單(dan),為(wei)便于磨損件(jian)的檢(jian)修更換,在中(zhong)間設計成(cheng)軸向剖分式,用螺栓(shuan)固定連接。
工(gong)作原理
物(wu)料(liao)(liao)由供料(liao)(liao)裝置(zhi)進入(ru)(ru)回轉滾筒(tong)(tong)的(de)(de)(de)(de)內(nei)層(ceng)(ceng)(ceng)(ceng),實(shi)現(xian)順流烘干(gan),物(wu)料(liao)(liao)在(zai)內(nei)層(ceng)(ceng)(ceng)(ceng)的(de)(de)(de)(de)抄(chao)板(ban)下不斷(duan)抄(chao)起(qi)、散(san)(san)落呈螺旋(xuan)行(xing)(xing)(xing)進式(shi)實(shi)現(xian)熱交換,物(wu)料(liao)(liao)移動至內(nei)層(ceng)(ceng)(ceng)(ceng)的(de)(de)(de)(de)另一端進入(ru)(ru)中(zhong)層(ceng)(ceng)(ceng)(ceng),進行(xing)(xing)(xing)逆流烘干(gan),物(wu)料(liao)(liao)在(zai)中(zhong)層(ceng)(ceng)(ceng)(ceng)不斷(duan)地被反復(fu)揚進,呈進兩(liang)步退(tui)一步的(de)(de)(de)(de)行(xing)(xing)(xing)進方式(shi),物(wu)料(liao)(liao)在(zai)中(zhong)層(ceng)(ceng)(ceng)(ceng)既充分吸收內(nei)層(ceng)(ceng)(ceng)(ceng)滾筒(tong)(tong)散(san)(san)發的(de)(de)(de)(de)熱量(liang),又吸收中(zhong)層(ceng)(ceng)(ceng)(ceng)滾筒(tong)(tong)的(de)(de)(de)(de)熱量(liang),同時又延長了干(gan)燥(zao)時間(jian),物(wu)料(liao)(liao)在(zai)此(ci)達(da)(da)到干(gan)燥(zao)狀態(tai)。物(wu)料(liao)(liao)行(xing)(xing)(xing)至中(zhong)層(ceng)(ceng)(ceng)(ceng)另一端而(er)落入(ru)(ru)外(wai)層(ceng)(ceng)(ceng)(ceng),物(wu)料(liao)(liao)在(zai)外(wai)層(ceng)(ceng)(ceng)(ceng)滾筒(tong)(tong)內(nei)呈矩形(xing)多回路方式(shi)行(xing)(xing)(xing)進,達(da)(da)到干(gan)燥(zao)效果(guo)的(de)(de)(de)(de)物(wu)料(liao)(liao)在(zai)熱風作用(yong)下快(kuai)速(su)(su)行(xing)(xing)(xing)進排(pai)出滾筒(tong)(tong),沒有達(da)(da)到干(gan)燥(zao)效果(guo)的(de)(de)(de)(de)濕(shi)物(wu)料(liao)(liao)因自重而(er)不能快(kuai)速(su)(su)行(xing)(xing)(xing)進,物(wu)料(liao)(liao)在(zai)此(ci)矩形(xing)抄(chao)板(ban)內(nei)進行(xing)(xing)(xing)充分干(gan)燥(zao),由此(ci)完(wan)成(cheng)干(gan)燥(zao)目的(de)(de)(de)(de)。
