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)(tong)體部分(fen)由三(san)個同軸水(shui)平放(fang)置的內、中、外筒(tong)(tong)套疊組(zu)成(cheng)，這就(jiu)使筒(tong)(tong)體的截面得到(dao)充分(fen)的利用。其筒(tong)(tong)體外形(xing)總長度(du)約為與之相當的單筒(tong)(tong)的30-35%。從而(er)大(da)幅度(du)地(di)減(jian)少占(zhan)地(di)面積和廠房建筑面積。
該(gai)機的(de)支(zhi)承裝置，是在(zai)外筒上(shang)輪帶與(yu)(yu)托(tuo)輪支(zhi)承，由電機直接帶動(dong)托(tuo)輪。通過(guo)托(tuo)輪與(yu)(yu)輪帶摩(mo)擦，使(shi)筒體轉動(dong)。該(gai)機總體結構緊(jin)湊、合理、簡單，為便(bian)于磨(mo)損件的(de)檢修(xiu)更換(huan)，在(zai)中間(jian)設計成軸向剖分式(shi)，用螺栓(shuan)固定連接。
工作原理
物(wu)(wu)(wu)料(liao)(liao)(liao)由供料(liao)(liao)(liao)裝置進(jin)入回轉滾(gun)筒(tong)的(de)內(nei)層(ceng),實現(xian)順流烘干(gan),物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)內(nei)層(ceng)的(de)抄板下不(bu)斷抄起、散落(luo)呈螺旋行(xing)(xing)(xing)(xing)進(jin)式(shi)實現(xian)熱交換，物(wu)(wu)(wu)料(liao)(liao)(liao)移動至(zhi)(zhi)內(nei)層(ceng)的(de)另(ling)一端進(jin)入中(zhong)(zhong)層(ceng)，進(jin)行(xing)(xing)(xing)(xing)逆流烘干(gan)，物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)中(zhong)(zhong)層(ceng)不(bu)斷地被反(fan)復揚進(jin)，呈進(jin)兩步退(tui)一步的(de)行(xing)(xing)(xing)(xing)進(jin)方式(shi)，物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)中(zhong)(zhong)層(ceng)既充分吸(xi)收內(nei)層(ceng)滾(gun)筒(tong)散發的(de)熱量，又吸(xi)收中(zhong)(zhong)層(ceng)滾(gun)筒(tong)的(de)熱量，同時(shi)又延(yan)長(chang)了干(gan)燥(zao)(zao)時(shi)間，物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)此(ci)達到干(gan)燥(zao)(zao)狀態。物(wu)(wu)(wu)料(liao)(liao)(liao)行(xing)(xing)(xing)(xing)至(zhi)(zhi)中(zhong)(zhong)層(ceng)另(ling)一端而落(luo)入外層(ceng)，物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)外層(ceng)滾(gun)筒(tong)內(nei)呈矩(ju)形(xing)多回路方式(shi)行(xing)(xing)(xing)(xing)進(jin)，達到干(gan)燥(zao)(zao)效果的(de)物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)熱風作用下快速(su)行(xing)(xing)(xing)(xing)進(jin)排出滾(gun)筒(tong)，沒(mei)有達到干(gan)燥(zao)(zao)效果的(de)濕物(wu)(wu)(wu)料(liao)(liao)(liao)因(yin)自重(zhong)而不(bu)能快速(su)行(xing)(xing)(xing)(xing)進(jin)，物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)此(ci)矩(ju)形(xing)抄板內(nei)進(jin)行(xing)(xing)(xing)(xing)充分干(gan)燥(zao)(zao)，由此(ci)完成干(gan)燥(zao)(zao)目的(de)。
