產品結(jie)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。
烘干機筒(tong)(tong)體(ti)部分由三個同(tong)軸水平(ping)放(fang)置的(de)內、中(zhong)、外筒(tong)(tong)套疊(die)組成,這就使筒(tong)(tong)體(ti)的(de)截面(mian)得到(dao)充(chong)分的(de)利(li)用。其筒(tong)(tong)體(ti)外形(xing)總長度約為與之相當的(de)單(dan)筒(tong)(tong)的(de)30-35%。從(cong)而大幅度地(di)減(jian)少占(zhan)地(di)面(mian)積和廠房建(jian)筑面(mian)積。
該機的支承裝置(zhi),是在(zai)(zai)外筒上輪(lun)帶與托(tuo)輪(lun)支承,由電機直(zhi)接帶動托(tuo)輪(lun)。通過托(tuo)輪(lun)與輪(lun)帶摩擦,使(shi)筒體轉動。該機總(zong)體結(jie)構緊湊、合理、簡單,為便于(yu)磨損件的檢修(xiu)更換(huan),在(zai)(zai)中間設計(ji)成軸向剖分式,用螺栓固定連(lian)接。
工作原理
物(wu)料(liao)(liao)(liao)(liao)(liao)(liao)(liao)由供料(liao)(liao)(liao)(liao)(liao)(liao)(liao)裝置進(jin)(jin)入(ru)(ru)回轉滾筒(tong)(tong)的(de)內(nei)(nei)層(ceng),實現順(shun)流烘干(gan)(gan),物(wu)料(liao)(liao)(liao)(liao)(liao)(liao)(liao)在內(nei)(nei)層(ceng)的(de)抄板(ban)下不斷抄起、散落呈螺旋行(xing)進(jin)(jin)式實現熱(re)交(jiao)換,物(wu)料(liao)(liao)(liao)(liao)(liao)(liao)(liao)移(yi)動至(zhi)內(nei)(nei)層(ceng)的(de)另(ling)一(yi)端進(jin)(jin)入(ru)(ru)中(zhong)層(ceng),進(jin)(jin)行(xing)逆(ni)流烘干(gan)(gan),物(wu)料(liao)(liao)(liao)(liao)(liao)(liao)(liao)在中(zhong)層(ceng)不斷地被(bei)反復揚進(jin)(jin),呈進(jin)(jin)兩步(bu)退一(yi)步(bu)的(de)行(xing)進(jin)(jin)方式,物(wu)料(liao)(liao)(liao)(liao)(liao)(liao)(liao)在中(zhong)層(ceng)既充(chong)分吸(xi)收內(nei)(nei)層(ceng)滾筒(tong)(tong)散發的(de)熱(re)量(liang),又(you)吸(xi)收中(zhong)層(ceng)滾筒(tong)(tong)的(de)熱(re)量(liang),同時又(you)延長了干(gan)(gan)燥(zao)(zao)時間,物(wu)料(liao)(liao)(liao)(liao)(liao)(liao)(liao)在此達(da)到(dao)干(gan)(gan)燥(zao)(zao)狀(zhuang)態。物(wu)料(liao)(liao)(liao)(liao)(liao)(liao)(liao)行(xing)至(zhi)中(zhong)層(ceng)另(ling)一(yi)端而落入(ru)(ru)外(wai)層(ceng),物(wu)料(liao)(liao)(liao)(liao)(liao)(liao)(liao)在外(wai)層(ceng)滾筒(tong)(tong)內(nei)(nei)呈矩(ju)形(xing)多回路方式行(xing)進(jin)(jin),達(da)到(dao)干(gan)(gan)燥(zao)(zao)效果的(de)物(wu)料(liao)(liao)(liao)(liao)(liao)(liao)(liao)在熱(re)風作用下快速(su)行(xing)進(jin)(jin)排出滾筒(tong)(tong),沒有達(da)到(dao)干(gan)(gan)燥(zao)(zao)效果的(de)濕物(wu)料(liao)(liao)(liao)(liao)(liao)(liao)(liao)因自重而不能快速(su)行(xing)進(jin)(jin),物(wu)料(liao)(liao)(liao)(liao)(liao)(liao)(liao)在此矩(ju)形(xing)抄板(ban)內(nei)(nei)進(jin)(jin)行(xing)充(chong)分干(gan)(gan)燥(zao)(zao),由此完成干(gan)(gan)燥(zao)(zao)目(mu)的(de)。
