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)(tong)體部分(fen)由三個同軸水平(ping)放(fang)置(zhi)的內、中、外筒(tong)(tong)(tong)套疊(die)組成，這就使筒(tong)(tong)(tong)體的截面得到充(chong)分(fen)的利(li)用。其筒(tong)(tong)(tong)體外形(xing)總長度約為與之相當的單(dan)筒(tong)(tong)(tong)的30-35%。從(cong)而大(da)幅度地減少占地面積和廠(chang)房(fang)建筑面積。

該機(ji)的(de)支(zhi)承(cheng)裝(zhuang)置(zhi)，是在外(wai)筒上輪(lun)(lun)帶與托(tuo)輪(lun)(lun)支(zhi)承(cheng)，由電機(ji)直(zhi)接(jie)帶動(dong)托(tuo)輪(lun)(lun)。通過托(tuo)輪(lun)(lun)與輪(lun)(lun)帶摩(mo)擦，使(shi)筒體(ti)轉(zhuan)動(dong)。該機(ji)總體(ti)結構緊湊(cou)、合理、簡單，為便于磨損件(jian)的(de)檢修更(geng)換，在中間設計(ji)成軸向剖(pou)分式，用螺(luo)栓固定連接(jie)。

工(gong)作(zuo)原理

物料(liao)(liao)(liao)由供料(liao)(liao)(liao)裝(zhuang)置(zhi)進入回(hui)轉滾筒(tong)(tong)(tong)的(de)(de)(de)內(nei)(nei)層(ceng)(ceng),實(shi)現(xian)順流烘干(gan)(gan),物料(liao)(liao)(liao)在(zai)(zai)內(nei)(nei)層(ceng)(ceng)的(de)(de)(de)抄(chao)板下不斷(duan)抄(chao)起、散落呈螺旋行(xing)(xing)(xing)進式實(shi)現(xian)熱(re)(re)交換(huan)，物料(liao)(liao)(liao)移動至內(nei)(nei)層(ceng)(ceng)的(de)(de)(de)另(ling)一(yi)(yi)端(duan)進入中(zhong)層(ceng)(ceng)，進行(xing)(xing)(xing)逆流烘干(gan)(gan)，物料(liao)(liao)(liao)在(zai)(zai)中(zhong)層(ceng)(ceng)不斷(duan)地被反復揚進，呈進兩步退一(yi)(yi)步的(de)(de)(de)行(xing)(xing)(xing)進方(fang)式，物料(liao)(liao)(liao)在(zai)(zai)中(zhong)層(ceng)(ceng)既充(chong)分(fen)吸收內(nei)(nei)層(ceng)(ceng)滾筒(tong)(tong)(tong)散發的(de)(de)(de)熱(re)(re)量(liang)，又吸收中(zhong)層(ceng)(ceng)滾筒(tong)(tong)(tong)的(de)(de)(de)熱(re)(re)量(liang)，同時又延長了干(gan)(gan)燥(zao)時間(jian)，物料(liao)(liao)(liao)在(zai)(zai)此(ci)達到(dao)干(gan)(gan)燥(zao)狀(zhuang)態。物料(liao)(liao)(liao)行(xing)(xing)(xing)至中(zhong)層(ceng)(ceng)另(ling)一(yi)(yi)端(duan)而落入外層(ceng)(ceng)，物料(liao)(liao)(liao)在(zai)(zai)外層(ceng)(ceng)滾筒(tong)(tong)(tong)內(nei)(nei)呈矩形多回(hui)路方(fang)式行(xing)(xing)(xing)進，達到(dao)干(gan)(gan)燥(zao)效果的(de)(de)(de)物料(liao)(liao)(liao)在(zai)(zai)熱(re)(re)風(feng)作用(yong)下快(kuai)速行(xing)(xing)(xing)進排出滾筒(tong)(tong)(tong)，沒(mei)有(you)達到(dao)干(gan)(gan)燥(zao)效果的(de)(de)(de)濕物料(liao)(liao)(liao)因自重而不能快(kuai)速行(xing)(xing)(xing)進，物料(liao)(liao)(liao)在(zai)(zai)此(ci)矩形抄(chao)板內(nei)(nei)進行(xing)(xing)(xing)充(chong)分(fen)干(gan)(gan)燥(zao)，由此(ci)完成(cheng)干(gan)(gan)燥(zao)目的(de)(de)(de)。
