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(ti)部分由三個(ge)同軸(zhou)水平放置的內、中、外筒(tong)(tong)套疊組(zu)成，這(zhe)就使筒(tong)(tong)體(ti)的截面得(de)到充(chong)分的利用(yong)。其筒(tong)(tong)體(ti)外形總長度(du)約(yue)為與之相(xiang)當的單筒(tong)(tong)的30-35%。從而大(da)幅度(du)地(di)減少占地(di)面積和廠房建筑面積。

該(gai)機的支(zhi)承(cheng)裝(zhuang)置，是在(zai)外筒(tong)上輪帶(dai)與(yu)托輪支(zhi)承(cheng)，由電機直接(jie)帶(dai)動托輪。通過托輪與(yu)輪帶(dai)摩擦，使筒(tong)體轉動。該(gai)機總(zong)體結構緊湊、合理、簡單(dan)，為便(bian)于磨損件的檢修更換，在(zai)中間設(she)計成軸向剖分(fen)式，用螺栓固(gu)定連接(jie)。

工(gong)作(zuo)原理

物(wu)(wu)料(liao)(liao)(liao)由供料(liao)(liao)(liao)裝置進(jin)(jin)(jin)(jin)(jin)(jin)入回轉滾筒(tong)(tong)(tong)的(de)(de)內層(ceng),實(shi)現順流烘(hong)干,物(wu)(wu)料(liao)(liao)(liao)在(zai)內層(ceng)的(de)(de)抄(chao)板下不斷(duan)抄(chao)起、散落呈螺(luo)旋行(xing)(xing)進(jin)(jin)(jin)(jin)(jin)(jin)式實(shi)現熱(re)交換，物(wu)(wu)料(liao)(liao)(liao)移動(dong)至(zhi)內層(ceng)的(de)(de)另(ling)一端(duan)進(jin)(jin)(jin)(jin)(jin)(jin)入中層(ceng)，進(jin)(jin)(jin)(jin)(jin)(jin)行(xing)(xing)逆流烘(hong)干，物(wu)(wu)料(liao)(liao)(liao)在(zai)中層(ceng)不斷(duan)地被反復揚進(jin)(jin)(jin)(jin)(jin)(jin)，呈進(jin)(jin)(jin)(jin)(jin)(jin)兩步退一步的(de)(de)行(xing)(xing)進(jin)(jin)(jin)(jin)(jin)(jin)方式，物(wu)(wu)料(liao)(liao)(liao)在(zai)中層(ceng)既充分吸(xi)收內層(ceng)滾筒(tong)(tong)(tong)散發的(de)(de)熱(re)量，又吸(xi)收中層(ceng)滾筒(tong)(tong)(tong)的(de)(de)熱(re)量，同時(shi)又延(yan)長了干燥(zao)(zao)時(shi)間，物(wu)(wu)料(liao)(liao)(liao)在(zai)此達到干燥(zao)(zao)狀態(tai)。物(wu)(wu)料(liao)(liao)(liao)行(xing)(xing)至(zhi)中層(ceng)另(ling)一端(duan)而落入外(wai)層(ceng)，物(wu)(wu)料(liao)(liao)(liao)在(zai)外(wai)層(ceng)滾筒(tong)(tong)(tong)內呈矩(ju)形(xing)多回路(lu)方式行(xing)(xing)進(jin)(jin)(jin)(jin)(jin)(jin)，達到干燥(zao)(zao)效(xiao)果的(de)(de)物(wu)(wu)料(liao)(liao)(liao)在(zai)熱(re)風作用下快速行(xing)(xing)進(jin)(jin)(jin)(jin)(jin)(jin)排(pai)出滾筒(tong)(tong)(tong)，沒有(you)達到干燥(zao)(zao)效(xiao)果的(de)(de)濕物(wu)(wu)料(liao)(liao)(liao)因自重而不能快速行(xing)(xing)進(jin)(jin)(jin)(jin)(jin)(jin)，物(wu)(wu)料(liao)(liao)(liao)在(zai)此矩(ju)形(xing)抄(chao)板內進(jin)(jin)(jin)(jin)(jin)(jin)行(xing)(xing)充分干燥(zao)(zao)，由此完成干燥(zao)(zao)目的(de)(de)。
