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)體部分(fen)由三個同軸水平(ping)放置的(de)(de)內、中、外(wai)筒(tong)套疊組成,這就使(shi)筒(tong)體的(de)(de)截面(mian)(mian)得到充分(fen)的(de)(de)利用(yong)。其筒(tong)體外(wai)形(xing)總長度約為與之相(xiang)當的(de)(de)單筒(tong)的(de)(de)30-35%。從而大幅度地(di)減少占(zhan)地(di)面(mian)(mian)積和廠(chang)房建筑面(mian)(mian)積。
該機(ji)的支(zhi)承(cheng)裝置,是在外(wai)筒(tong)上輪帶(dai)與托(tuo)輪支(zhi)承(cheng),由電機(ji)直接帶(dai)動托(tuo)輪。通過(guo)托(tuo)輪與輪帶(dai)摩(mo)擦,使筒(tong)體轉動。該機(ji)總體結構緊(jin)湊、合(he)理、簡(jian)單,為便于磨損件的檢修更換,在中間設計成軸向(xiang)剖分(fen)式(shi),用螺栓固定(ding)連接。
工作原理
物(wu)料(liao)(liao)(liao)(liao)由供(gong)料(liao)(liao)(liao)(liao)裝置進(jin)(jin)入回轉(zhuan)滾(gun)筒的(de)內(nei)(nei)層(ceng)(ceng)(ceng),實現順流烘干,物(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)內(nei)(nei)層(ceng)(ceng)(ceng)的(de)抄(chao)板下不斷(duan)(duan)抄(chao)起(qi)、散落(luo)呈(cheng)螺旋行(xing)(xing)(xing)進(jin)(jin)式(shi)實現熱交換,物(wu)料(liao)(liao)(liao)(liao)移動(dong)至內(nei)(nei)層(ceng)(ceng)(ceng)的(de)另(ling)一(yi)端(duan)進(jin)(jin)入中層(ceng)(ceng)(ceng),進(jin)(jin)行(xing)(xing)(xing)逆流烘干,物(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)中層(ceng)(ceng)(ceng)不斷(duan)(duan)地被反復揚進(jin)(jin),呈(cheng)進(jin)(jin)兩步退一(yi)步的(de)行(xing)(xing)(xing)進(jin)(jin)方式(shi),物(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)中層(ceng)(ceng)(ceng)既充分吸收(shou)內(nei)(nei)層(ceng)(ceng)(ceng)滾(gun)筒散發的(de)熱量,又吸收(shou)中層(ceng)(ceng)(ceng)滾(gun)筒的(de)熱量,同時又延長了干燥時間,物(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)此(ci)達(da)到(dao)(dao)干燥狀態。物(wu)料(liao)(liao)(liao)(liao)行(xing)(xing)(xing)至中層(ceng)(ceng)(ceng)另(ling)一(yi)端(duan)而落(luo)入外(wai)層(ceng)(ceng)(ceng),物(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)外(wai)層(ceng)(ceng)(ceng)滾(gun)筒內(nei)(nei)呈(cheng)矩形(xing)(xing)多回路方式(shi)行(xing)(xing)(xing)進(jin)(jin),達(da)到(dao)(dao)干燥效果的(de)物(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)熱風作用下快(kuai)速(su)(su)行(xing)(xing)(xing)進(jin)(jin)排出滾(gun)筒,沒有達(da)到(dao)(dao)干燥效果的(de)濕物(wu)料(liao)(liao)(liao)(liao)因(yin)自重(zhong)而不能快(kuai)速(su)(su)行(xing)(xing)(xing)進(jin)(jin),物(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)此(ci)矩形(xing)(xing)抄(chao)板內(nei)(nei)進(jin)(jin)行(xing)(xing)(xing)充分干燥,由此(ci)完成干燥目的(de)。
