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。
烘干機筒體部(bu)分由三個同軸水(shui)平放置(zhi)的內(nei)、中(zhong)、外筒套疊組成(cheng),這(zhe)就使筒體的截(jie)面(mian)得到充分的利用。其筒體外形總長度(du)約為與(yu)之相(xiang)當(dang)的單筒的30-35%。從(cong)而(er)大幅度(du)地減少占地面(mian)積(ji)和廠房建筑面(mian)積(ji)。
該機的支承(cheng)裝置,是在外筒上輪帶(dai)與托輪支承(cheng),由(you)電機直接(jie)帶(dai)動托輪。通過托輪與輪帶(dai)摩擦,使筒體(ti)轉動。該機總體(ti)結構緊湊(cou)、合理、簡單,為便(bian)于磨(mo)損件的檢修更換(huan),在中間設計成軸向剖分式,用螺栓(shuan)固定連接(jie)。
工作(zuo)原理
物(wu)(wu)(wu)(wu)料(liao)(liao)由供料(liao)(liao)裝置(zhi)進(jin)(jin)(jin)(jin)入回(hui)轉滾(gun)筒(tong)的(de)(de)(de)內(nei)(nei)(nei)層(ceng)(ceng)(ceng),實(shi)現(xian)(xian)順流(liu)烘干,物(wu)(wu)(wu)(wu)料(liao)(liao)在內(nei)(nei)(nei)層(ceng)(ceng)(ceng)的(de)(de)(de)抄(chao)板(ban)下(xia)不(bu)斷抄(chao)起(qi)、散(san)落呈螺旋行進(jin)(jin)(jin)(jin)式實(shi)現(xian)(xian)熱(re)(re)交換,物(wu)(wu)(wu)(wu)料(liao)(liao)移動至(zhi)內(nei)(nei)(nei)層(ceng)(ceng)(ceng)的(de)(de)(de)另一端進(jin)(jin)(jin)(jin)入中(zhong)(zhong)層(ceng)(ceng)(ceng),進(jin)(jin)(jin)(jin)行逆流(liu)烘干,物(wu)(wu)(wu)(wu)料(liao)(liao)在中(zhong)(zhong)層(ceng)(ceng)(ceng)不(bu)斷地(di)被反(fan)復(fu)揚進(jin)(jin)(jin)(jin),呈進(jin)(jin)(jin)(jin)兩(liang)步(bu)退一步(bu)的(de)(de)(de)行進(jin)(jin)(jin)(jin)方式,物(wu)(wu)(wu)(wu)料(liao)(liao)在中(zhong)(zhong)層(ceng)(ceng)(ceng)既充分(fen)吸收內(nei)(nei)(nei)層(ceng)(ceng)(ceng)滾(gun)筒(tong)散(san)發的(de)(de)(de)熱(re)(re)量,又(you)(you)吸收中(zhong)(zhong)層(ceng)(ceng)(ceng)滾(gun)筒(tong)的(de)(de)(de)熱(re)(re)量,同時又(you)(you)延長了干燥時間,物(wu)(wu)(wu)(wu)料(liao)(liao)在此達到(dao)(dao)干燥狀(zhuang)態。物(wu)(wu)(wu)(wu)料(liao)(liao)行至(zhi)中(zhong)(zhong)層(ceng)(ceng)(ceng)另一端而落入外層(ceng)(ceng)(ceng),物(wu)(wu)(wu)(wu)料(liao)(liao)在外層(ceng)(ceng)(ceng)滾(gun)筒(tong)內(nei)(nei)(nei)呈矩形(xing)(xing)多(duo)回(hui)路方式行進(jin)(jin)(jin)(jin),達到(dao)(dao)干燥效果(guo)(guo)的(de)(de)(de)物(wu)(wu)(wu)(wu)料(liao)(liao)在熱(re)(re)風作(zuo)用下(xia)快(kuai)速行進(jin)(jin)(jin)(jin)排出滾(gun)筒(tong),沒有達到(dao)(dao)干燥效果(guo)(guo)的(de)(de)(de)濕物(wu)(wu)(wu)(wu)料(liao)(liao)因自重而不(bu)能快(kuai)速行進(jin)(jin)(jin)(jin),物(wu)(wu)(wu)(wu)料(liao)(liao)在此矩形(xing)(xing)抄(chao)板(ban)內(nei)(nei)(nei)進(jin)(jin)(jin)(jin)行充分(fen)干燥,由此完成干燥目(mu)的(de)(de)(de)。
