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。
烘干機筒(tong)體(ti)(ti)部分由(you)三(san)個同(tong)軸水(shui)平放置的內、中、外筒(tong)套疊組成(cheng),這就使筒(tong)體(ti)(ti)的截面(mian)得到充分的利用。其筒(tong)體(ti)(ti)外形總長度約為與之相(xiang)當的單筒(tong)的30-35%。從而大幅度地減(jian)少占地面(mian)積(ji)和廠房建筑(zhu)面(mian)積(ji)。
該機(ji)(ji)(ji)的支承裝置,是在(zai)外筒(tong)上輪帶與(yu)托(tuo)輪支承,由電機(ji)(ji)(ji)直(zhi)接帶動(dong)托(tuo)輪。通過托(tuo)輪與(yu)輪帶摩(mo)擦(ca),使筒(tong)體轉動(dong)。該機(ji)(ji)(ji)總體結構緊(jin)湊、合理(li)、簡(jian)單,為(wei)便于(yu)磨(mo)損件的檢修更換,在(zai)中間設計成軸向剖分式,用螺栓固定連接。
工作原理
物(wu)(wu)(wu)(wu)(wu)(wu)料(liao)由供料(liao)裝置進(jin)(jin)(jin)入(ru)回轉滾(gun)筒的(de)(de)(de)內層(ceng)(ceng)(ceng)(ceng),實(shi)現順(shun)流烘干(gan)(gan)(gan),物(wu)(wu)(wu)(wu)(wu)(wu)料(liao)在(zai)(zai)內層(ceng)(ceng)(ceng)(ceng)的(de)(de)(de)抄(chao)板(ban)下不(bu)斷抄(chao)起、散落呈螺旋行(xing)進(jin)(jin)(jin)式(shi)實(shi)現熱交換(huan),物(wu)(wu)(wu)(wu)(wu)(wu)料(liao)移動至內層(ceng)(ceng)(ceng)(ceng)的(de)(de)(de)另一(yi)端(duan)進(jin)(jin)(jin)入(ru)中層(ceng)(ceng)(ceng)(ceng),進(jin)(jin)(jin)行(xing)逆流烘干(gan)(gan)(gan),物(wu)(wu)(wu)(wu)(wu)(wu)料(liao)在(zai)(zai)中層(ceng)(ceng)(ceng)(ceng)不(bu)斷地被反(fan)復揚進(jin)(jin)(jin),呈進(jin)(jin)(jin)兩步(bu)(bu)退一(yi)步(bu)(bu)的(de)(de)(de)行(xing)進(jin)(jin)(jin)方式(shi),物(wu)(wu)(wu)(wu)(wu)(wu)料(liao)在(zai)(zai)中層(ceng)(ceng)(ceng)(ceng)既充分吸(xi)收(shou)內層(ceng)(ceng)(ceng)(ceng)滾(gun)筒散發的(de)(de)(de)熱量(liang),又(you)吸(xi)收(shou)中層(ceng)(ceng)(ceng)(ceng)滾(gun)筒的(de)(de)(de)熱量(liang),同時又(you)延長(chang)了(le)干(gan)(gan)(gan)燥(zao)時間,物(wu)(wu)(wu)(wu)(wu)(wu)料(liao)在(zai)(zai)此(ci)(ci)達(da)到干(gan)(gan)(gan)燥(zao)狀態。物(wu)(wu)(wu)(wu)(wu)(wu)料(liao)行(xing)至中層(ceng)(ceng)(ceng)(ceng)另一(yi)端(duan)而落入(ru)外層(ceng)(ceng)(ceng)(ceng),物(wu)(wu)(wu)(wu)(wu)(wu)料(liao)在(zai)(zai)外層(ceng)(ceng)(ceng)(ceng)滾(gun)筒內呈矩形多回路方式(shi)行(xing)進(jin)(jin)(jin),達(da)到干(gan)(gan)(gan)燥(zao)效果的(de)(de)(de)物(wu)(wu)(wu)(wu)(wu)(wu)料(liao)在(zai)(zai)熱風作用下快速行(xing)進(jin)(jin)(jin)排出滾(gun)筒,沒有達(da)到干(gan)(gan)(gan)燥(zao)效果的(de)(de)(de)濕物(wu)(wu)(wu)(wu)(wu)(wu)料(liao)因自重而不(bu)能快速行(xing)進(jin)(jin)(jin),物(wu)(wu)(wu)(wu)(wu)(wu)料(liao)在(zai)(zai)此(ci)(ci)矩形抄(chao)板(ban)內進(jin)(jin)(jin)行(xing)充分干(gan)(gan)(gan)燥(zao),由此(ci)(ci)完成干(gan)(gan)(gan)燥(zao)目的(de)(de)(de)。
