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(ji)筒(tong)(tong)體部(bu)分由三個同(tong)軸水平放置的內、中、外(wai)筒(tong)(tong)套疊組成,這就使筒(tong)(tong)體的截面(mian)得(de)到(dao)充分的利用。其筒(tong)(tong)體外(wai)形總長(chang)度約為與(yu)之相當的單筒(tong)(tong)的30-35%。從而大幅度地減少(shao)占地面(mian)積(ji)和廠房建筑面(mian)積(ji)。
該(gai)機的(de)支(zhi)承裝置,是在外(wai)筒上輪帶與托輪支(zhi)承,由電機直(zhi)接(jie)帶動(dong)托輪。通過托輪與輪帶摩(mo)擦,使筒體(ti)轉動(dong)。該(gai)機總體(ti)結(jie)構(gou)緊(jin)湊、合理、簡單,為便(bian)于(yu)磨損件的(de)檢修更(geng)換,在中間設計(ji)成軸向剖分式(shi),用螺栓固定連接(jie)。
工作原理
物(wu)(wu)料(liao)(liao)(liao)由供料(liao)(liao)(liao)裝(zhuang)置進(jin)入(ru)回轉滾筒的(de)內(nei)層(ceng)(ceng),實現順流(liu)(liu)烘干(gan)(gan),物(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)(zai)內(nei)層(ceng)(ceng)的(de)抄板(ban)下(xia)不(bu)斷抄起、散(san)落呈(cheng)螺(luo)旋行(xing)(xing)進(jin)式實現熱(re)交(jiao)換(huan),物(wu)(wu)料(liao)(liao)(liao)移動至(zhi)內(nei)層(ceng)(ceng)的(de)另(ling)一(yi)(yi)端(duan)進(jin)入(ru)中(zhong)(zhong)層(ceng)(ceng),進(jin)行(xing)(xing)逆流(liu)(liu)烘干(gan)(gan),物(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)(zai)中(zhong)(zhong)層(ceng)(ceng)不(bu)斷地被反復揚進(jin),呈(cheng)進(jin)兩步(bu)退一(yi)(yi)步(bu)的(de)行(xing)(xing)進(jin)方(fang)(fang)式,物(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)(zai)中(zhong)(zhong)層(ceng)(ceng)既充分吸(xi)收內(nei)層(ceng)(ceng)滾筒散(san)發的(de)熱(re)量,又(you)吸(xi)收中(zhong)(zhong)層(ceng)(ceng)滾筒的(de)熱(re)量,同時(shi)又(you)延長(chang)了干(gan)(gan)燥(zao)時(shi)間,物(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)(zai)此(ci)達到干(gan)(gan)燥(zao)狀態。物(wu)(wu)料(liao)(liao)(liao)行(xing)(xing)至(zhi)中(zhong)(zhong)層(ceng)(ceng)另(ling)一(yi)(yi)端(duan)而落入(ru)外層(ceng)(ceng),物(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)(zai)外層(ceng)(ceng)滾筒內(nei)呈(cheng)矩(ju)形多回路(lu)方(fang)(fang)式行(xing)(xing)進(jin),達到干(gan)(gan)燥(zao)效果(guo)的(de)物(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)(zai)熱(re)風作用(yong)下(xia)快速行(xing)(xing)進(jin)排出(chu)滾筒,沒有達到干(gan)(gan)燥(zao)效果(guo)的(de)濕物(wu)(wu)料(liao)(liao)(liao)因自重(zhong)而不(bu)能快速行(xing)(xing)進(jin),物(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)(zai)此(ci)矩(ju)形抄板(ban)內(nei)進(jin)行(xing)(xing)充分干(gan)(gan)燥(zao),由此(ci)完成干(gan)(gan)燥(zao)目的(de)。
