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(tong)體部分由(you)三個同軸水平放置的(de)(de)(de)(de)內、中、外筒(tong)套疊組成,這(zhe)就使筒(tong)體的(de)(de)(de)(de)截面得到(dao)充(chong)分的(de)(de)(de)(de)利(li)用。其筒(tong)體外形總長度約為與之相當的(de)(de)(de)(de)單筒(tong)的(de)(de)(de)(de)30-35%。從(cong)而大幅度地(di)減少占(zhan)地(di)面積(ji)和(he)廠房建筑面積(ji)。
該機的支(zhi)承裝置,是在(zai)外筒上輪(lun)帶(dai)與托輪(lun)支(zhi)承,由電機直接(jie)帶(dai)動托輪(lun)。通過托輪(lun)與輪(lun)帶(dai)摩擦(ca),使(shi)筒體(ti)轉動。該機總體(ti)結構緊湊、合理、簡(jian)單,為(wei)便于磨損件的檢修(xiu)更(geng)換,在(zai)中間設計(ji)成(cheng)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)(liao)由供料(liao)(liao)(liao)裝置(zhi)進(jin)(jin)入(ru)(ru)回(hui)轉滾(gun)筒(tong)(tong)的(de)(de)(de)(de)內(nei)(nei)(nei)層(ceng)(ceng)(ceng),實現順(shun)流烘干(gan),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在內(nei)(nei)(nei)層(ceng)(ceng)(ceng)的(de)(de)(de)(de)抄板(ban)下不斷抄起、散落呈(cheng)螺(luo)旋行(xing)(xing)(xing)進(jin)(jin)式實現熱交換,物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)移動(dong)至內(nei)(nei)(nei)層(ceng)(ceng)(ceng)的(de)(de)(de)(de)另一(yi)端進(jin)(jin)入(ru)(ru)中(zhong)層(ceng)(ceng)(ceng),進(jin)(jin)行(xing)(xing)(xing)逆流烘干(gan),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在中(zhong)層(ceng)(ceng)(ceng)不斷地被反(fan)復揚進(jin)(jin),呈(cheng)進(jin)(jin)兩步(bu)退一(yi)步(bu)的(de)(de)(de)(de)行(xing)(xing)(xing)進(jin)(jin)方(fang)式,物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在中(zhong)層(ceng)(ceng)(ceng)既充(chong)分吸(xi)收內(nei)(nei)(nei)層(ceng)(ceng)(ceng)滾(gun)筒(tong)(tong)散發(fa)的(de)(de)(de)(de)熱量,又(you)吸(xi)收中(zhong)層(ceng)(ceng)(ceng)滾(gun)筒(tong)(tong)的(de)(de)(de)(de)熱量,同時(shi)又(you)延長了(le)干(gan)燥(zao)時(shi)間(jian),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在此達(da)到干(gan)燥(zao)狀態。物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)行(xing)(xing)(xing)至中(zhong)層(ceng)(ceng)(ceng)另一(yi)端而落入(ru)(ru)外層(ceng)(ceng)(ceng),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在外層(ceng)(ceng)(ceng)滾(gun)筒(tong)(tong)內(nei)(nei)(nei)呈(cheng)矩(ju)形多回(hui)路方(fang)式行(xing)(xing)(xing)進(jin)(jin),達(da)到干(gan)燥(zao)效果的(de)(de)(de)(de)物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在熱風作用下快(kuai)速行(xing)(xing)(xing)進(jin)(jin)排出滾(gun)筒(tong)(tong),沒有達(da)到干(gan)燥(zao)效果的(de)(de)(de)(de)濕物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)因(yin)自重而不能(neng)快(kuai)速行(xing)(xing)(xing)進(jin)(jin),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在此矩(ju)形抄板(ban)內(nei)(nei)(nei)進(jin)(jin)行(xing)(xing)(xing)充(chong)分干(gan)燥(zao),由此完成干(gan)燥(zao)目的(de)(de)(de)(de)。
