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。
烘干機(ji)筒(tong)(tong)體部分由三個(ge)同軸水平放置的(de)(de)內、中、外(wai)筒(tong)(tong)套疊(die)組成,這就使(shi)筒(tong)(tong)體的(de)(de)截面得到(dao)充分的(de)(de)利(li)用。其筒(tong)(tong)體外(wai)形總長度約為與之(zhi)相當(dang)的(de)(de)單筒(tong)(tong)的(de)(de)30-35%。從而大幅度地減少占地面積和廠(chang)房建筑面積。
該機(ji)的(de)支承裝置(zhi),是在外筒上輪帶(dai)與托輪支承,由(you)電(dian)機(ji)直(zhi)接(jie)帶(dai)動托輪。通過(guo)托輪與輪帶(dai)摩擦,使(shi)筒體轉(zhuan)動。該機(ji)總體結構緊湊(cou)、合理、簡單,為便于磨損件的(de)檢修更換,在中間設計成軸(zhou)向(xiang)剖分式,用螺栓固定連接(jie)。
工(gong)作原理
物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)由供料(liao)(liao)(liao)裝置進(jin)(jin)(jin)入回轉滾(gun)筒(tong)的(de)(de)(de)內(nei)層(ceng)(ceng),實現(xian)順流烘(hong)干(gan),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)內(nei)層(ceng)(ceng)的(de)(de)(de)抄(chao)(chao)板(ban)(ban)下不(bu)(bu)斷抄(chao)(chao)起、散落呈螺旋行(xing)(xing)(xing)(xing)進(jin)(jin)(jin)式實現(xian)熱交換,物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)移動至(zhi)內(nei)層(ceng)(ceng)的(de)(de)(de)另一(yi)端進(jin)(jin)(jin)入中(zhong)層(ceng)(ceng),進(jin)(jin)(jin)行(xing)(xing)(xing)(xing)逆(ni)流烘(hong)干(gan),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)中(zhong)層(ceng)(ceng)不(bu)(bu)斷地被反復揚進(jin)(jin)(jin),呈進(jin)(jin)(jin)兩步退一(yi)步的(de)(de)(de)行(xing)(xing)(xing)(xing)進(jin)(jin)(jin)方(fang)式,物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)中(zhong)層(ceng)(ceng)既充分吸收內(nei)層(ceng)(ceng)滾(gun)筒(tong)散發的(de)(de)(de)熱量(liang),又(you)吸收中(zhong)層(ceng)(ceng)滾(gun)筒(tong)的(de)(de)(de)熱量(liang),同時(shi)又(you)延長了干(gan)燥(zao)時(shi)間,物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)此(ci)達到(dao)干(gan)燥(zao)狀態。物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)行(xing)(xing)(xing)(xing)至(zhi)中(zhong)層(ceng)(ceng)另一(yi)端而(er)落入外層(ceng)(ceng),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)外層(ceng)(ceng)滾(gun)筒(tong)內(nei)呈矩形多回路方(fang)式行(xing)(xing)(xing)(xing)進(jin)(jin)(jin),達到(dao)干(gan)燥(zao)效果的(de)(de)(de)物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)熱風作(zuo)用(yong)下快(kuai)速行(xing)(xing)(xing)(xing)進(jin)(jin)(jin)排出滾(gun)筒(tong),沒有達到(dao)干(gan)燥(zao)效果的(de)(de)(de)濕物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)因自重而(er)不(bu)(bu)能快(kuai)速行(xing)(xing)(xing)(xing)進(jin)(jin)(jin),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)此(ci)矩形抄(chao)(chao)板(ban)(ban)內(nei)進(jin)(jin)(jin)行(xing)(xing)(xing)(xing)充分干(gan)燥(zao),由此(ci)完成干(gan)燥(zao)目的(de)(de)(de)。
