產品結構
三筒烘(hong)(hong)干(gan)機是(shi)通過對單筒烘(hong)(hong)干(gan)機的單筒體(ti)改為套疊在一起的三筒,以縮短烘(hong)(hong)干(gan)機體(ti)的外(wai)形(xing)尺寸。該機工(gong)作時,物料(liao)(liao)和熱氣流(liu)依(yi)次(ci)進入內至外(wai)筒體(ti),在機體(ti)Z形(xing)往(wang)復折流(liu)后,充分(fen)利用熱能烘(hong)(hong)干(gan)物料(liao)(liao)后再卸(xie)出。
烘干(gan)機筒體部分(fen)由(you)三(san)個同軸水平放置的(de)內、中(zhong)、外筒套疊組成,這就(jiu)使(shi)筒體的(de)截面(mian)得到(dao)充分(fen)的(de)利(li)用(yong)。其筒體外形總長度(du)約(yue)為與之相當的(de)單筒的(de)30-35%。從(cong)而大幅度(du)地減(jian)少占(zhan)地面(mian)積和廠(chang)房建筑面(mian)積。
該機(ji)的(de)支(zhi)承裝(zhuang)置,是在(zai)外筒上輪(lun)(lun)帶(dai)與托(tuo)輪(lun)(lun)支(zhi)承,由電機(ji)直接帶(dai)動(dong)托(tuo)輪(lun)(lun)。通過托(tuo)輪(lun)(lun)與輪(lun)(lun)帶(dai)摩擦,使筒體轉動(dong)。該機(ji)總體結構緊(jin)湊、合(he)理、簡單,為便(bian)于磨損件的(de)檢修(xiu)更換,在(zai)中間設(she)計成軸向剖分(fen)式,用螺栓固(gu)定(ding)連接。
工作原理
物(wu)(wu)(wu)(wu)(wu)(wu)(wu)料由供(gong)料裝(zhuang)置進(jin)(jin)入(ru)回轉(zhuan)滾(gun)(gun)筒(tong)的(de)(de)(de)內(nei)層(ceng)(ceng)(ceng),實(shi)現順流烘(hong)干(gan)(gan),物(wu)(wu)(wu)(wu)(wu)(wu)(wu)料在(zai)內(nei)層(ceng)(ceng)(ceng)的(de)(de)(de)抄板(ban)下不斷抄起、散落(luo)呈(cheng)螺旋行(xing)(xing)(xing)進(jin)(jin)式(shi)實(shi)現熱交(jiao)換,物(wu)(wu)(wu)(wu)(wu)(wu)(wu)料移動至(zhi)內(nei)層(ceng)(ceng)(ceng)的(de)(de)(de)另一端進(jin)(jin)入(ru)中(zhong)層(ceng)(ceng)(ceng),進(jin)(jin)行(xing)(xing)(xing)逆(ni)流烘(hong)干(gan)(gan),物(wu)(wu)(wu)(wu)(wu)(wu)(wu)料在(zai)中(zhong)層(ceng)(ceng)(ceng)不斷地被反復揚進(jin)(jin),呈(cheng)進(jin)(jin)兩步退一步的(de)(de)(de)行(xing)(xing)(xing)進(jin)(jin)方(fang)式(shi),物(wu)(wu)(wu)(wu)(wu)(wu)(wu)料在(zai)中(zhong)層(ceng)(ceng)(ceng)既充(chong)分吸收(shou)內(nei)層(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)散發(fa)的(de)(de)(de)熱量(liang)(liang),又吸收(shou)中(zhong)層(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)的(de)(de)(de)熱量(liang)(liang),同時(shi)又延(yan)長了干(gan)(gan)燥(zao)(zao)時(shi)間(jian),物(wu)(wu)(wu)(wu)(wu)(wu)(wu)料在(zai)此達到干(gan)(gan)燥(zao)(zao)狀態。物(wu)(wu)(wu)(wu)(wu)(wu)(wu)料行(xing)(xing)(xing)至(zhi)中(zhong)層(ceng)(ceng)(ceng)另一端而落(luo)入(ru)外(wai)層(ceng)(ceng)(ceng),物(wu)(wu)(wu)(wu)(wu)(wu)(wu)料在(zai)外(wai)層(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)內(nei)呈(cheng)矩形多回路方(fang)式(shi)行(xing)(xing)(xing)進(jin)(jin),達到干(gan)(gan)燥(zao)(zao)效(xiao)果的(de)(de)(de)物(wu)(wu)(wu)(wu)(wu)(wu)(wu)料在(zai)熱風作用下快速行(xing)(xing)(xing)進(jin)(jin)排出滾(gun)(gun)筒(tong),沒有(you)達到干(gan)(gan)燥(zao)(zao)效(xiao)果的(de)(de)(de)濕(shi)物(wu)(wu)(wu)(wu)(wu)(wu)(wu)料因自(zi)重而不能(neng)快速行(xing)(xing)(xing)進(jin)(jin),物(wu)(wu)(wu)(wu)(wu)(wu)(wu)料在(zai)此矩形抄板(ban)內(nei)進(jin)(jin)行(xing)(xing)(xing)充(chong)分干(gan)(gan)燥(zao)(zao),由此完成干(gan)(gan)燥(zao)(zao)目的(de)(de)(de)。
