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)體部分由三(san)個同軸水平放置的(de)(de)內、中、外(wai)筒(tong)套疊組成,這(zhe)就使筒(tong)體的(de)(de)截面(mian)得到充分的(de)(de)利用。其筒(tong)體外(wai)形總長度約為與之相當的(de)(de)單筒(tong)的(de)(de)30-35%。從而大幅度地減(jian)少占地面(mian)積(ji)(ji)和(he)廠房建筑面(mian)積(ji)(ji)。
該機(ji)的(de)支承裝置(zhi),是在外筒上輪(lun)(lun)(lun)(lun)帶與托輪(lun)(lun)(lun)(lun)支承,由電(dian)機(ji)直接(jie)帶動托輪(lun)(lun)(lun)(lun)。通過托輪(lun)(lun)(lun)(lun)與輪(lun)(lun)(lun)(lun)帶摩擦,使筒體轉動。該機(ji)總體結(jie)構(gou)緊(jin)湊(cou)、合理(li)、簡(jian)單,為便于磨損(sun)件的(de)檢修更換(huan),在中間(jian)設計(ji)成(cheng)軸(zhou)向剖分式,用螺栓固定連接(jie)。
工作(zuo)原理
物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)由(you)供料(liao)(liao)(liao)(liao)(liao)裝置進(jin)(jin)(jin)(jin)(jin)入(ru)回轉滾筒(tong)(tong)(tong)的(de)(de)(de)(de)內(nei)層(ceng)(ceng)(ceng)(ceng),實現(xian)順流(liu)烘干,物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)內(nei)層(ceng)(ceng)(ceng)(ceng)的(de)(de)(de)(de)抄(chao)(chao)板(ban)下不斷抄(chao)(chao)起、散落呈螺旋行(xing)(xing)進(jin)(jin)(jin)(jin)(jin)式實現(xian)熱(re)交換,物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)移(yi)動(dong)至(zhi)內(nei)層(ceng)(ceng)(ceng)(ceng)的(de)(de)(de)(de)另一(yi)端(duan)進(jin)(jin)(jin)(jin)(jin)入(ru)中(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng),進(jin)(jin)(jin)(jin)(jin)行(xing)(xing)逆流(liu)烘干,物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)中(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)不斷地被反復揚進(jin)(jin)(jin)(jin)(jin),呈進(jin)(jin)(jin)(jin)(jin)兩步退(tui)一(yi)步的(de)(de)(de)(de)行(xing)(xing)進(jin)(jin)(jin)(jin)(jin)方式,物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)中(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)既(ji)充分(fen)(fen)吸收內(nei)層(ceng)(ceng)(ceng)(ceng)滾筒(tong)(tong)(tong)散發的(de)(de)(de)(de)熱(re)量,又(you)吸收中(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)滾筒(tong)(tong)(tong)的(de)(de)(de)(de)熱(re)量,同時又(you)延長了干燥時間,物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)此達到干燥狀態(tai)。物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)行(xing)(xing)至(zhi)中(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)另一(yi)端(duan)而落入(ru)外(wai)層(ceng)(ceng)(ceng)(ceng),物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)外(wai)層(ceng)(ceng)(ceng)(ceng)滾筒(tong)(tong)(tong)內(nei)呈矩形多(duo)回路方式行(xing)(xing)進(jin)(jin)(jin)(jin)(jin),達到干燥效果(guo)(guo)的(de)(de)(de)(de)物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)熱(re)風作(zuo)用下快(kuai)速行(xing)(xing)進(jin)(jin)(jin)(jin)(jin)排出滾筒(tong)(tong)(tong),沒有達到干燥效果(guo)(guo)的(de)(de)(de)(de)濕物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)因自重而不能快(kuai)速行(xing)(xing)進(jin)(jin)(jin)(jin)(jin),物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)此矩形抄(chao)(chao)板(ban)內(nei)進(jin)(jin)(jin)(jin)(jin)行(xing)(xing)充分(fen)(fen)干燥,由(you)此完成干燥目的(de)(de)(de)(de)。
