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(hong)干機筒體部分由三個(ge)同軸水平(ping)放置的內、中、外(wai)筒套疊組成,這就使筒體的截面得到(dao)充分的利用。其筒體外(wai)形總長度(du)約為(wei)與之相當的單筒的30-35%。從而大幅度(du)地減少占地面積和(he)廠(chang)房建筑面積。
該(gai)機的(de)支承裝置,是在(zai)外筒(tong)上輪帶(dai)(dai)與托輪支承,由電機直接帶(dai)(dai)動托輪。通過(guo)托輪與輪帶(dai)(dai)摩擦(ca),使筒(tong)體(ti)轉動。該(gai)機總體(ti)結構緊(jin)湊、合理、簡單(dan),為便(bian)于(yu)磨損件的(de)檢修更換,在(zai)中間設計成(cheng)軸(zhou)向剖分(fen)式,用螺栓固定(ding)連接。
工作原理
物(wu)料(liao)(liao)(liao)(liao)(liao)由供料(liao)(liao)(liao)(liao)(liao)裝(zhuang)置進入回(hui)轉滾(gun)筒(tong)(tong)的(de)(de)內(nei)層(ceng)(ceng)(ceng),實(shi)現順流烘(hong)干(gan),物(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)內(nei)層(ceng)(ceng)(ceng)的(de)(de)抄(chao)(chao)板下(xia)不(bu)(bu)斷抄(chao)(chao)起、散(san)落(luo)呈(cheng)(cheng)螺旋行(xing)(xing)進式(shi)實(shi)現熱(re)(re)交(jiao)換,物(wu)料(liao)(liao)(liao)(liao)(liao)移動至內(nei)層(ceng)(ceng)(ceng)的(de)(de)另一(yi)端進入中(zhong)層(ceng)(ceng)(ceng),進行(xing)(xing)逆流烘(hong)干(gan),物(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)中(zhong)層(ceng)(ceng)(ceng)不(bu)(bu)斷地被反(fan)復揚進,呈(cheng)(cheng)進兩步(bu)退(tui)一(yi)步(bu)的(de)(de)行(xing)(xing)進方式(shi),物(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)中(zhong)層(ceng)(ceng)(ceng)既充分吸(xi)收(shou)內(nei)層(ceng)(ceng)(ceng)滾(gun)筒(tong)(tong)散(san)發的(de)(de)熱(re)(re)量,又(you)吸(xi)收(shou)中(zhong)層(ceng)(ceng)(ceng)滾(gun)筒(tong)(tong)的(de)(de)熱(re)(re)量,同時又(you)延長了(le)干(gan)燥(zao)時間,物(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)此(ci)達到(dao)干(gan)燥(zao)狀態。物(wu)料(liao)(liao)(liao)(liao)(liao)行(xing)(xing)至中(zhong)層(ceng)(ceng)(ceng)另一(yi)端而落(luo)入外層(ceng)(ceng)(ceng),物(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)外層(ceng)(ceng)(ceng)滾(gun)筒(tong)(tong)內(nei)呈(cheng)(cheng)矩形多回(hui)路方式(shi)行(xing)(xing)進,達到(dao)干(gan)燥(zao)效果的(de)(de)物(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)熱(re)(re)風作用下(xia)快速行(xing)(xing)進排出(chu)滾(gun)筒(tong)(tong),沒有(you)達到(dao)干(gan)燥(zao)效果的(de)(de)濕(shi)物(wu)料(liao)(liao)(liao)(liao)(liao)因自重而不(bu)(bu)能(neng)快速行(xing)(xing)進,物(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)此(ci)矩形抄(chao)(chao)板內(nei)進行(xing)(xing)充分干(gan)燥(zao),由此(ci)完成干(gan)燥(zao)目的(de)(de)。
