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(tong)(tong)體(ti)部分(fen)由三個同軸(zhou)水平放(fang)置的內、中(zhong)、外筒(tong)(tong)套(tao)疊組成，這就使筒(tong)(tong)體(ti)的截面(mian)得到(dao)充分(fen)的利用。其筒(tong)(tong)體(ti)外形總長度約為與之相當的單筒(tong)(tong)的30-35%。從(cong)而大幅度地(di)減少占地(di)面(mian)積和廠房建筑面(mian)積。
該機的支(zhi)承裝置，是在外筒上(shang)輪(lun)(lun)帶(dai)與(yu)(yu)托(tuo)輪(lun)(lun)支(zhi)承，由電機直接帶(dai)動托(tuo)輪(lun)(lun)。通過(guo)托(tuo)輪(lun)(lun)與(yu)(yu)輪(lun)(lun)帶(dai)摩(mo)擦，使筒體(ti)轉動。該機總體(ti)結(jie)構緊湊、合理、簡單，為(wei)便于磨損件的檢修(xiu)更換，在中間(jian)設計(ji)成軸向(xiang)剖分式，用螺栓固定連接。
工作原(yuan)理
物(wu)(wu)(wu)料(liao)(liao)由(you)供料(liao)(liao)裝(zhuang)置進入(ru)回轉滾筒的內(nei)(nei)層(ceng)(ceng)(ceng),實現順流(liu)烘(hong)干(gan),物(wu)(wu)(wu)料(liao)(liao)在(zai)內(nei)(nei)層(ceng)(ceng)(ceng)的抄(chao)板下不斷(duan)抄(chao)起、散落呈螺旋行(xing)(xing)(xing)進式實現熱(re)(re)交換，物(wu)(wu)(wu)料(liao)(liao)移動至內(nei)(nei)層(ceng)(ceng)(ceng)的另(ling)一(yi)端進入(ru)中(zhong)(zhong)層(ceng)(ceng)(ceng)，進行(xing)(xing)(xing)逆流(liu)烘(hong)干(gan)，物(wu)(wu)(wu)料(liao)(liao)在(zai)中(zhong)(zhong)層(ceng)(ceng)(ceng)不斷(duan)地被反復揚進，呈進兩步退一(yi)步的行(xing)(xing)(xing)進方(fang)式，物(wu)(wu)(wu)料(liao)(liao)在(zai)中(zhong)(zhong)層(ceng)(ceng)(ceng)既充(chong)分(fen)吸收內(nei)(nei)層(ceng)(ceng)(ceng)滾筒散發的熱(re)(re)量，又吸收中(zhong)(zhong)層(ceng)(ceng)(ceng)滾筒的熱(re)(re)量，同時(shi)(shi)又延長了干(gan)燥(zao)(zao)(zao)(zao)時(shi)(shi)間，物(wu)(wu)(wu)料(liao)(liao)在(zai)此達(da)到干(gan)燥(zao)(zao)(zao)(zao)狀態。物(wu)(wu)(wu)料(liao)(liao)行(xing)(xing)(xing)至中(zhong)(zhong)層(ceng)(ceng)(ceng)另(ling)一(yi)端而落入(ru)外層(ceng)(ceng)(ceng)，物(wu)(wu)(wu)料(liao)(liao)在(zai)外層(ceng)(ceng)(ceng)滾筒內(nei)(nei)呈矩形(xing)多回路方(fang)式行(xing)(xing)(xing)進，達(da)到干(gan)燥(zao)(zao)(zao)(zao)效果的物(wu)(wu)(wu)料(liao)(liao)在(zai)熱(re)(re)風(feng)作用(yong)下快速行(xing)(xing)(xing)進排出滾筒，沒(mei)有達(da)到干(gan)燥(zao)(zao)(zao)(zao)效果的濕物(wu)(wu)(wu)料(liao)(liao)因(yin)自重而不能快速行(xing)(xing)(xing)進，物(wu)(wu)(wu)料(liao)(liao)在(zai)此矩形(xing)抄(chao)板內(nei)(nei)進行(xing)(xing)(xing)充(chong)分(fen)干(gan)燥(zao)(zao)(zao)(zao)，由(you)此完成(cheng)干(gan)燥(zao)(zao)(zao)(zao)目的。
