產品結構
大型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。
烘干機筒體(ti)部分(fen)由三個同軸水平放置(zhi)的(de)內、中、外(wai)筒套疊組成,這就使筒體(ti)的(de)截面得到充分(fen)的(de)利用。其筒體(ti)外(wai)形總(zong)長(chang)度(du)約為與之相當的(de)單筒的(de)30-35%。從而大幅度(du)地(di)減(jian)少(shao)占(zhan)地(di)面積(ji)和廠房(fang)建(jian)筑面積(ji)。
該(gai)機的(de)支承(cheng)裝(zhuang)置,是在外筒上輪帶(dai)與托(tuo)輪支承(cheng),由電機直接(jie)帶(dai)動托(tuo)輪。通過托(tuo)輪與輪帶(dai)摩擦,使(shi)筒體轉動。該(gai)機總體結構緊(jin)湊、合理、簡單,為(wei)便(bian)于磨損件的(de)檢修(xiu)更換(huan),在中間設計成軸(zhou)向剖分式,用(yong)螺栓(shuan)固定連接(jie)。
工作原理
物(wu)(wu)(wu)(wu)料(liao)由供料(liao)裝置進入回(hui)轉滾(gun)(gun)筒(tong)的(de)內(nei)(nei)層(ceng)(ceng)(ceng)(ceng),實(shi)現(xian)順流烘(hong)(hong)干(gan),物(wu)(wu)(wu)(wu)料(liao)在(zai)(zai)內(nei)(nei)層(ceng)(ceng)(ceng)(ceng)的(de)抄板(ban)下(xia)不(bu)斷(duan)抄起、散落呈螺旋行(xing)(xing)(xing)進式實(shi)現(xian)熱交換,物(wu)(wu)(wu)(wu)料(liao)移動(dong)至內(nei)(nei)層(ceng)(ceng)(ceng)(ceng)的(de)另一(yi)端(duan)(duan)進入中(zhong)層(ceng)(ceng)(ceng)(ceng),進行(xing)(xing)(xing)逆流烘(hong)(hong)干(gan),物(wu)(wu)(wu)(wu)料(liao)在(zai)(zai)中(zhong)層(ceng)(ceng)(ceng)(ceng)不(bu)斷(duan)地被反復揚進,呈進兩步退一(yi)步的(de)行(xing)(xing)(xing)進方(fang)式,物(wu)(wu)(wu)(wu)料(liao)在(zai)(zai)中(zhong)層(ceng)(ceng)(ceng)(ceng)既充分(fen)吸(xi)(xi)收(shou)(shou)內(nei)(nei)層(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)散發的(de)熱量,又吸(xi)(xi)收(shou)(shou)中(zhong)層(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)的(de)熱量,同時(shi)又延長了干(gan)燥(zao)(zao)時(shi)間,物(wu)(wu)(wu)(wu)料(liao)在(zai)(zai)此達到干(gan)燥(zao)(zao)狀(zhuang)態。物(wu)(wu)(wu)(wu)料(liao)行(xing)(xing)(xing)至中(zhong)層(ceng)(ceng)(ceng)(ceng)另一(yi)端(duan)(duan)而落入外層(ceng)(ceng)(ceng)(ceng),物(wu)(wu)(wu)(wu)料(liao)在(zai)(zai)外層(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)內(nei)(nei)呈矩(ju)形(xing)多回(hui)路(lu)方(fang)式行(xing)(xing)(xing)進,達到干(gan)燥(zao)(zao)效(xiao)果的(de)物(wu)(wu)(wu)(wu)料(liao)在(zai)(zai)熱風作用下(xia)快(kuai)速行(xing)(xing)(xing)進排出滾(gun)(gun)筒(tong),沒有達到干(gan)燥(zao)(zao)效(xiao)果的(de)濕物(wu)(wu)(wu)(wu)料(liao)因(yin)自重而不(bu)能快(kuai)速行(xing)(xing)(xing)進,物(wu)(wu)(wu)(wu)料(liao)在(zai)(zai)此矩(ju)形(xing)抄板(ban)內(nei)(nei)進行(xing)(xing)(xing)充分(fen)干(gan)燥(zao)(zao),由此完成干(gan)燥(zao)(zao)目的(de)。
