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。
烘干機筒體(ti)部分(fen)由(you)三個同軸水平放置的(de)內(nei)、中、外筒套(tao)疊組成,這就使筒體(ti)的(de)截面得到充分(fen)的(de)利用。其筒體(ti)外形總長度約為與之相當的(de)單筒的(de)30-35%。從而大幅度地減少占地面積和廠房建筑面積。
該機的(de)支承裝置,是在外筒上輪帶與(yu)托(tuo)輪支承,由電機直接(jie)帶動托(tuo)輪。通(tong)過托(tuo)輪與(yu)輪帶摩擦,使筒體轉動。該機總(zong)體結構(gou)緊湊、合理(li)、簡單,為(wei)便于磨損件的(de)檢修更換,在中間設(she)計成軸向剖(pou)分式,用螺栓(shuan)固定(ding)連接(jie)。
工作原理(li)
物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)由供料(liao)(liao)(liao)(liao)(liao)裝(zhuang)置進(jin)入(ru)回(hui)轉(zhuan)滾(gun)(gun)筒(tong)的(de)內(nei)層(ceng)(ceng)(ceng)(ceng),實(shi)現順流烘干(gan),物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在內(nei)層(ceng)(ceng)(ceng)(ceng)的(de)抄板下(xia)不斷抄起(qi)、散(san)落呈螺旋行(xing)進(jin)式(shi)實(shi)現熱(re)(re)交換,物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)移(yi)動至(zhi)內(nei)層(ceng)(ceng)(ceng)(ceng)的(de)另(ling)一端進(jin)入(ru)中(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng),進(jin)行(xing)逆流烘干(gan),物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在中(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)不斷地被反復揚進(jin),呈進(jin)兩(liang)步(bu)退一步(bu)的(de)行(xing)進(jin)方式(shi),物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在中(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)既充分吸收內(nei)層(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)散(san)發的(de)熱(re)(re)量,又吸收中(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)的(de)熱(re)(re)量,同時又延長了干(gan)燥(zao)時間,物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在此達到(dao)干(gan)燥(zao)狀態。物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)行(xing)至(zhi)中(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)另(ling)一端而落入(ru)外(wai)(wai)層(ceng)(ceng)(ceng)(ceng),物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在外(wai)(wai)層(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)內(nei)呈矩(ju)形(xing)多(duo)回(hui)路方式(shi)行(xing)進(jin),達到(dao)干(gan)燥(zao)效果(guo)的(de)物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在熱(re)(re)風作用下(xia)快(kuai)速行(xing)進(jin)排出(chu)滾(gun)(gun)筒(tong),沒有(you)達到(dao)干(gan)燥(zao)效果(guo)的(de)濕物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)因自重而不能快(kuai)速行(xing)進(jin),物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在此矩(ju)形(xing)抄板內(nei)進(jin)行(xing)充分干(gan)燥(zao),由此完成干(gan)燥(zao)目的(de)。
