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)部分由三個同軸水平放置的(de)內、中(zhong)、外筒套疊組成,這就使筒體(ti)的(de)截面得到充分的(de)利用。其筒體(ti)外形總長(chang)度(du)約(yue)為與之相當的(de)單筒的(de)30-35%。從而(er)大(da)幅(fu)度(du)地(di)(di)減少占(zhan)地(di)(di)面積(ji)和廠房建筑(zhu)面積(ji)。
該機的支承(cheng)裝置,是在外筒上輪(lun)(lun)帶(dai)(dai)與(yu)托(tuo)(tuo)輪(lun)(lun)支承(cheng),由(you)電(dian)機直接帶(dai)(dai)動托(tuo)(tuo)輪(lun)(lun)。通過托(tuo)(tuo)輪(lun)(lun)與(yu)輪(lun)(lun)帶(dai)(dai)摩(mo)擦,使筒體轉動。該機總體結構緊湊、合(he)理、簡(jian)單(dan),為(wei)便于磨(mo)損件(jian)的檢修更換,在中(zhong)間設計成軸向剖分式,用(yong)螺栓固定連接。
工作(zuo)原理
物料(liao)(liao)由供料(liao)(liao)裝(zhuang)置進(jin)(jin)(jin)入回轉滾(gun)(gun)筒(tong)的(de)內(nei)(nei)層(ceng)(ceng)(ceng)(ceng)(ceng),實現順流烘(hong)干(gan),物料(liao)(liao)在(zai)(zai)內(nei)(nei)層(ceng)(ceng)(ceng)(ceng)(ceng)的(de)抄(chao)板下(xia)不斷抄(chao)起、散落呈螺(luo)旋行(xing)(xing)進(jin)(jin)(jin)式實現熱交換,物料(liao)(liao)移(yi)動至(zhi)內(nei)(nei)層(ceng)(ceng)(ceng)(ceng)(ceng)的(de)另(ling)一端進(jin)(jin)(jin)入中層(ceng)(ceng)(ceng)(ceng)(ceng),進(jin)(jin)(jin)行(xing)(xing)逆流烘(hong)干(gan),物料(liao)(liao)在(zai)(zai)中層(ceng)(ceng)(ceng)(ceng)(ceng)不斷地被(bei)反復揚進(jin)(jin)(jin),呈進(jin)(jin)(jin)兩步退一步的(de)行(xing)(xing)進(jin)(jin)(jin)方式,物料(liao)(liao)在(zai)(zai)中層(ceng)(ceng)(ceng)(ceng)(ceng)既(ji)充(chong)(chong)分吸收(shou)內(nei)(nei)層(ceng)(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)散發的(de)熱量,又(you)吸收(shou)中層(ceng)(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)的(de)熱量,同時又(you)延長(chang)了干(gan)燥(zao)時間(jian),物料(liao)(liao)在(zai)(zai)此達到(dao)干(gan)燥(zao)狀態。物料(liao)(liao)行(xing)(xing)至(zhi)中層(ceng)(ceng)(ceng)(ceng)(ceng)另(ling)一端而(er)落入外(wai)層(ceng)(ceng)(ceng)(ceng)(ceng),物料(liao)(liao)在(zai)(zai)外(wai)層(ceng)(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)內(nei)(nei)呈矩形多回路方式行(xing)(xing)進(jin)(jin)(jin),達到(dao)干(gan)燥(zao)效果的(de)物料(liao)(liao)在(zai)(zai)熱風作(zuo)用下(xia)快速行(xing)(xing)進(jin)(jin)(jin)排出滾(gun)(gun)筒(tong),沒有達到(dao)干(gan)燥(zao)效果的(de)濕物料(liao)(liao)因(yin)自重而(er)不能快速行(xing)(xing)進(jin)(jin)(jin),物料(liao)(liao)在(zai)(zai)此矩形抄(chao)板內(nei)(nei)進(jin)(jin)(jin)行(xing)(xing)充(chong)(chong)分干(gan)燥(zao),由此完成干(gan)燥(zao)目的(de)。
