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(ti)部分(fen)(fen)由三(san)個同(tong)軸水平放置的(de)內、中、外筒(tong)(tong)套疊組成，這就使(shi)筒(tong)(tong)體(ti)的(de)截面得到(dao)充分(fen)(fen)的(de)利(li)用。其(qi)筒(tong)(tong)體(ti)外形(xing)總長度約為與(yu)之相當(dang)的(de)單筒(tong)(tong)的(de)30-35%。從而大幅度地(di)減少占地(di)面積(ji)和廠房建筑(zhu)面積(ji)。
該機的支(zhi)(zhi)承裝置，是在(zai)外筒上輪帶與(yu)托輪支(zhi)(zhi)承，由電機直接(jie)帶動(dong)托輪。通(tong)過托輪與(yu)輪帶摩擦，使筒體轉動(dong)。該機總體結構緊湊、合理(li)、簡單，為便于磨(mo)損件的檢修更換，在(zai)中(zhong)間設計成軸向剖分式，用螺栓固定連接(jie)。
工作(zuo)原理
物(wu)(wu)(wu)料(liao)由供料(liao)裝置進(jin)(jin)(jin)入回(hui)轉滾(gun)(gun)筒(tong)(tong)(tong)(tong)的(de)(de)內層(ceng)(ceng),實現順流烘干(gan)(gan)(gan),物(wu)(wu)(wu)料(liao)在(zai)內層(ceng)(ceng)的(de)(de)抄(chao)板(ban)下(xia)不(bu)斷(duan)抄(chao)起、散落呈螺旋行(xing)(xing)進(jin)(jin)(jin)式(shi)實現熱(re)交(jiao)換，物(wu)(wu)(wu)料(liao)移動(dong)至內層(ceng)(ceng)的(de)(de)另(ling)一(yi)端(duan)進(jin)(jin)(jin)入中(zhong)層(ceng)(ceng)，進(jin)(jin)(jin)行(xing)(xing)逆流烘干(gan)(gan)(gan)，物(wu)(wu)(wu)料(liao)在(zai)中(zhong)層(ceng)(ceng)不(bu)斷(duan)地被(bei)反復揚進(jin)(jin)(jin)，呈進(jin)(jin)(jin)兩步退一(yi)步的(de)(de)行(xing)(xing)進(jin)(jin)(jin)方式(shi)，物(wu)(wu)(wu)料(liao)在(zai)中(zhong)層(ceng)(ceng)既充分吸(xi)收內層(ceng)(ceng)滾(gun)(gun)筒(tong)(tong)(tong)(tong)散發的(de)(de)熱(re)量，又(you)(you)吸(xi)收中(zhong)層(ceng)(ceng)滾(gun)(gun)筒(tong)(tong)(tong)(tong)的(de)(de)熱(re)量，同時(shi)又(you)(you)延長了干(gan)(gan)(gan)燥時(shi)間，物(wu)(wu)(wu)料(liao)在(zai)此達到干(gan)(gan)(gan)燥狀態。物(wu)(wu)(wu)料(liao)行(xing)(xing)至中(zhong)層(ceng)(ceng)另(ling)一(yi)端(duan)而(er)落入外層(ceng)(ceng)，物(wu)(wu)(wu)料(liao)在(zai)外層(ceng)(ceng)滾(gun)(gun)筒(tong)(tong)(tong)(tong)內呈矩形多回(hui)路方式(shi)行(xing)(xing)進(jin)(jin)(jin)，達到干(gan)(gan)(gan)燥效(xiao)果(guo)的(de)(de)物(wu)(wu)(wu)料(liao)在(zai)熱(re)風作用下(xia)快速(su)行(xing)(xing)進(jin)(jin)(jin)排出滾(gun)(gun)筒(tong)(tong)(tong)(tong)，沒(mei)有達到干(gan)(gan)(gan)燥效(xiao)果(guo)的(de)(de)濕物(wu)(wu)(wu)料(liao)因自重(zhong)而(er)不(bu)能快速(su)行(xing)(xing)進(jin)(jin)(jin)，物(wu)(wu)(wu)料(liao)在(zai)此矩形抄(chao)板(ban)內進(jin)(jin)(jin)行(xing)(xing)充分干(gan)(gan)(gan)燥，由此完成干(gan)(gan)(gan)燥目的(de)(de)。
