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)(tong)體部分(fen)由三個同軸水(shui)平放(fang)置(zhi)的(de)內、中、外(wai)(wai)筒(tong)(tong)套疊組(zu)成,這就使筒(tong)(tong)體的(de)截面(mian)得到充(chong)分(fen)的(de)利(li)用。其筒(tong)(tong)體外(wai)(wai)形總長度約為與之(zhi)相當的(de)單筒(tong)(tong)的(de)30-35%。從而大幅(fu)度地減少(shao)占地面(mian)積(ji)和廠房建筑面(mian)積(ji)。
該(gai)機的支(zhi)承(cheng)裝(zhuang)置,是在(zai)外筒上輪帶與托輪支(zhi)承(cheng),由(you)電機直(zhi)接帶動(dong)托輪。通(tong)過托輪與輪帶摩擦,使筒體轉動(dong)。該(gai)機總體結(jie)構緊湊、合理(li)、簡單(dan),為(wei)便(bian)于磨損件(jian)的檢(jian)修更換,在(zai)中間設計成軸向剖分式,用螺(luo)栓固定連(lian)接。
工作原理
物(wu)(wu)(wu)料(liao)由(you)供料(liao)裝置進(jin)(jin)(jin)(jin)(jin)入回轉滾(gun)筒(tong)的(de)(de)內(nei)(nei)層(ceng),實(shi)現(xian)順流(liu)烘干,物(wu)(wu)(wu)料(liao)在(zai)(zai)(zai)內(nei)(nei)層(ceng)的(de)(de)抄(chao)板(ban)下(xia)不斷抄(chao)起、散落(luo)呈螺旋行(xing)進(jin)(jin)(jin)(jin)(jin)式(shi)實(shi)現(xian)熱(re)交換,物(wu)(wu)(wu)料(liao)移動至內(nei)(nei)層(ceng)的(de)(de)另一端(duan)(duan)進(jin)(jin)(jin)(jin)(jin)入中(zhong)層(ceng),進(jin)(jin)(jin)(jin)(jin)行(xing)逆流(liu)烘干,物(wu)(wu)(wu)料(liao)在(zai)(zai)(zai)中(zhong)層(ceng)不斷地被反復揚進(jin)(jin)(jin)(jin)(jin),呈進(jin)(jin)(jin)(jin)(jin)兩步退一步的(de)(de)行(xing)進(jin)(jin)(jin)(jin)(jin)方式(shi),物(wu)(wu)(wu)料(liao)在(zai)(zai)(zai)中(zhong)層(ceng)既充(chong)分(fen)吸(xi)(xi)收內(nei)(nei)層(ceng)滾(gun)筒(tong)散發的(de)(de)熱(re)量,又(you)吸(xi)(xi)收中(zhong)層(ceng)滾(gun)筒(tong)的(de)(de)熱(re)量,同時又(you)延長了干燥時間,物(wu)(wu)(wu)料(liao)在(zai)(zai)(zai)此(ci)(ci)達到(dao)干燥狀(zhuang)態(tai)。物(wu)(wu)(wu)料(liao)行(xing)至中(zhong)層(ceng)另一端(duan)(duan)而落(luo)入外層(ceng),物(wu)(wu)(wu)料(liao)在(zai)(zai)(zai)外層(ceng)滾(gun)筒(tong)內(nei)(nei)呈矩(ju)形(xing)多回路方式(shi)行(xing)進(jin)(jin)(jin)(jin)(jin),達到(dao)干燥效果的(de)(de)物(wu)(wu)(wu)料(liao)在(zai)(zai)(zai)熱(re)風作用(yong)下(xia)快速(su)(su)行(xing)進(jin)(jin)(jin)(jin)(jin)排(pai)出滾(gun)筒(tong),沒有達到(dao)干燥效果的(de)(de)濕物(wu)(wu)(wu)料(liao)因自重而不能(neng)快速(su)(su)行(xing)進(jin)(jin)(jin)(jin)(jin),物(wu)(wu)(wu)料(liao)在(zai)(zai)(zai)此(ci)(ci)矩(ju)形(xing)抄(chao)板(ban)內(nei)(nei)進(jin)(jin)(jin)(jin)(jin)行(xing)充(chong)分(fen)干燥,由(you)此(ci)(ci)完成干燥目的(de)(de)。
