產品結構
三筒式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(fen)由三(san)個同軸水平放置的內(nei)、中(zhong)、外筒套疊組成(cheng),這就(jiu)使筒體的截(jie)面得到充(chong)分(fen)的利(li)用。其筒體外形總長度(du)約為與之相當的單筒的30-35%。從而大幅度(du)地(di)減少占地(di)面積和廠房建筑面積。
該機的支承(cheng)裝置(zhi),是在(zai)外筒(tong)上輪(lun)(lun)帶(dai)與托(tuo)(tuo)輪(lun)(lun)支承(cheng),由電機直(zhi)接帶(dai)動(dong)托(tuo)(tuo)輪(lun)(lun)。通過(guo)托(tuo)(tuo)輪(lun)(lun)與輪(lun)(lun)帶(dai)摩擦,使筒(tong)體(ti)轉動(dong)。該機總體(ti)結構緊湊、合理、簡單,為便(bian)于磨損件的檢修更換,在(zai)中間設計成軸向剖分式(shi),用螺栓固定連(lian)接。
工作原理
物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)由(you)供料(liao)(liao)(liao)裝置進(jin)(jin)入回(hui)轉滾(gun)筒(tong)的(de)(de)(de)內(nei)層(ceng)(ceng),實(shi)現順流烘干(gan)(gan)(gan),物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)內(nei)層(ceng)(ceng)的(de)(de)(de)抄(chao)板(ban)下不斷抄(chao)起、散落呈螺旋(xuan)行(xing)(xing)(xing)進(jin)(jin)式(shi)實(shi)現熱交換,物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)移(yi)動至內(nei)層(ceng)(ceng)的(de)(de)(de)另一(yi)端進(jin)(jin)入中(zhong)層(ceng)(ceng),進(jin)(jin)行(xing)(xing)(xing)逆流烘干(gan)(gan)(gan),物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)中(zhong)層(ceng)(ceng)不斷地被反復揚進(jin)(jin),呈進(jin)(jin)兩(liang)步(bu)退(tui)一(yi)步(bu)的(de)(de)(de)行(xing)(xing)(xing)進(jin)(jin)方式(shi),物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)中(zhong)層(ceng)(ceng)既充(chong)分吸收內(nei)層(ceng)(ceng)滾(gun)筒(tong)散發(fa)的(de)(de)(de)熱量,又吸收中(zhong)層(ceng)(ceng)滾(gun)筒(tong)的(de)(de)(de)熱量,同時又延長了干(gan)(gan)(gan)燥(zao)(zao)(zao)時間,物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)此(ci)達到干(gan)(gan)(gan)燥(zao)(zao)(zao)狀態(tai)。物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)行(xing)(xing)(xing)至中(zhong)層(ceng)(ceng)另一(yi)端而落入外(wai)層(ceng)(ceng),物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)外(wai)層(ceng)(ceng)滾(gun)筒(tong)內(nei)呈矩形(xing)多回(hui)路方式(shi)行(xing)(xing)(xing)進(jin)(jin),達到干(gan)(gan)(gan)燥(zao)(zao)(zao)效果的(de)(de)(de)物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)熱風作用下快速行(xing)(xing)(xing)進(jin)(jin)排出滾(gun)筒(tong),沒(mei)有達到干(gan)(gan)(gan)燥(zao)(zao)(zao)效果的(de)(de)(de)濕(shi)物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)因自重而不能快速行(xing)(xing)(xing)進(jin)(jin),物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)此(ci)矩形(xing)抄(chao)板(ban)內(nei)進(jin)(jin)行(xing)(xing)(xing)充(chong)分干(gan)(gan)(gan)燥(zao)(zao)(zao),由(you)此(ci)完成干(gan)(gan)(gan)燥(zao)(zao)(zao)目的(de)(de)(de)。
