產品結構
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(hong)干機筒體部分(fen)由三(san)個同軸水平放置(zhi)的內、中、外筒套疊組成,這就使筒體的截面得到充(chong)分(fen)的利用。其筒體外形總長度(du)約為與之相當的單筒的30-35%。從而大幅(fu)度(du)地減少占地面積和廠(chang)房建筑面積。
該機的支(zhi)承裝置,是在外筒(tong)(tong)上輪(lun)帶(dai)與托輪(lun)支(zhi)承,由電(dian)機直接(jie)帶(dai)動托輪(lun)。通過托輪(lun)與輪(lun)帶(dai)摩擦,使(shi)筒(tong)(tong)體轉(zhuan)動。該機總體結構緊湊、合(he)理、簡(jian)單,為便于(yu)磨損(sun)件的檢修更換,在中間設計成軸(zhou)向剖(pou)分式,用螺(luo)栓固定連(lian)接(jie)。
工作(zuo)原理
物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)由供料(liao)(liao)(liao)(liao)裝置進(jin)入回(hui)轉滾(gun)筒(tong)(tong)的(de)內(nei)(nei)(nei)層(ceng)(ceng),實(shi)(shi)現(xian)順(shun)流(liu)烘干(gan)(gan)(gan),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)內(nei)(nei)(nei)層(ceng)(ceng)的(de)抄板(ban)下不斷(duan)抄起、散落呈螺旋行(xing)(xing)進(jin)式(shi)實(shi)(shi)現(xian)熱(re)交換,物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)移動至內(nei)(nei)(nei)層(ceng)(ceng)的(de)另一端(duan)進(jin)入中層(ceng)(ceng),進(jin)行(xing)(xing)逆流(liu)烘干(gan)(gan)(gan),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)中層(ceng)(ceng)不斷(duan)地(di)被反復(fu)揚進(jin),呈進(jin)兩步退一步的(de)行(xing)(xing)進(jin)方式(shi),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)中層(ceng)(ceng)既(ji)充分(fen)吸收內(nei)(nei)(nei)層(ceng)(ceng)滾(gun)筒(tong)(tong)散發的(de)熱(re)量(liang),又(you)吸收中層(ceng)(ceng)滾(gun)筒(tong)(tong)的(de)熱(re)量(liang),同時又(you)延長了(le)干(gan)(gan)(gan)燥(zao)(zao)時間,物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)此達到干(gan)(gan)(gan)燥(zao)(zao)狀態。物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)行(xing)(xing)至中層(ceng)(ceng)另一端(duan)而落入外層(ceng)(ceng),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)外層(ceng)(ceng)滾(gun)筒(tong)(tong)內(nei)(nei)(nei)呈矩形多回(hui)路方式(shi)行(xing)(xing)進(jin),達到干(gan)(gan)(gan)燥(zao)(zao)效果的(de)物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)熱(re)風(feng)作用下快速行(xing)(xing)進(jin)排出滾(gun)筒(tong)(tong),沒有達到干(gan)(gan)(gan)燥(zao)(zao)效果的(de)濕物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)因(yin)自重(zhong)而不能快速行(xing)(xing)進(jin),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)此矩形抄板(ban)內(nei)(nei)(nei)進(jin)行(xing)(xing)充分(fen)干(gan)(gan)(gan)燥(zao)(zao),由此完成干(gan)(gan)(gan)燥(zao)(zao)目(mu)的(de)。
