產品概(gai)況

三筒烘干機是在單筒回轉式烘干機基礎上改進的節能產品。

回轉式(shi)三筒烘(hong)干機改進(jin)原(yuan)單(dan)(dan)筒烘(hong)干機內部(bu)結構，增加入機前(qian)濕料的預烘(hong)干和(he)延長濕料在機內烘(hong)干時間，再加上密(mi)封、保溫以(yi)及合理的配套措(cuo)施，使(shi)烘(hong)干機生產能力與原(yuan)單(dan)(dan)筒式(shi)烘(hong)干機相比，提高48-80%，單(dan)(dan)位容積蒸發強度可(ke)達120-180kg/m3，標(biao)準煤(mei)耗僅(jin)為6-8kg/t。其(qi)技術先進(jin)、運行參數合理，操作簡單(dan)(dan)可(ke)行，廣泛應用于(yu)各個行業(ye)的礦渣、粘(zhan)土、煤(mei)。

產品結(jie)構

三筒(tong)(tong)烘干機(ji)是通過對單(dan)筒(tong)(tong)烘干機(ji)的(de)單(dan)筒(tong)(tong)體(ti)改為套(tao)疊在(zai)一起的(de)三筒(tong)(tong)，以縮短烘干機(ji)體(ti)的(de)外形尺(chi)寸。該機(ji)工作(zuo)時，物料和熱氣流依次進入內至外筒(tong)(tong)體(ti)，在(zai)機(ji)體(ti)Z形往復(fu)折流后，充(chong)分利用熱能烘干物料后再卸出。

烘干機筒體部分(fen)由三(san)個同軸(zhou)水平放置的(de)內(nei)、中(zhong)、外筒套(tao)疊(die)組成(cheng)，這就使筒體的(de)截面得到充分(fen)的(de)利(li)用。其筒體外形總長度約為與之(zhi)相當的(de)單筒的(de)30-35%。從而大幅度地減(jian)少占地面積和(he)廠房(fang)建筑面積。

該(gai)機(ji)的(de)(de)支(zhi)承裝(zhuang)置，是在外筒上輪帶(dai)與(yu)托輪支(zhi)承，由(you)電機(ji)直接帶(dai)動(dong)托輪。通過(guo)托輪與(yu)輪帶(dai)摩擦，使筒體(ti)轉動(dong)。該(gai)機(ji)總體(ti)結構緊湊、合理、簡單，為便于(yu)磨(mo)損件的(de)(de)檢修更換，在中間(jian)設計成軸向剖分(fen)式(shi)，用螺(luo)栓固定連接。

工作(zuo)原(yuan)理(li)

物(wu)料(liao)由(you)供料(liao)裝置進入(ru)回轉滾(gun)筒(tong)(tong)(tong)的(de)內層(ceng)(ceng),實現(xian)順流烘(hong)干(gan)(gan),物(wu)料(liao)在(zai)(zai)內層(ceng)(ceng)的(de)抄(chao)板(ban)下不(bu)斷抄(chao)起、散(san)落呈(cheng)螺旋行(xing)(xing)(xing)進式實現(xian)熱(re)交換，物(wu)料(liao)移動至內層(ceng)(ceng)的(de)另(ling)一端(duan)進入(ru)中(zhong)(zhong)層(ceng)(ceng)，進行(xing)(xing)(xing)逆(ni)流烘(hong)干(gan)(gan)，物(wu)料(liao)在(zai)(zai)中(zhong)(zhong)層(ceng)(ceng)不(bu)斷地被反復(fu)揚(yang)進，呈(cheng)進兩步退(tui)一步的(de)行(xing)(xing)(xing)進方式，物(wu)料(liao)在(zai)(zai)中(zhong)(zhong)層(ceng)(ceng)既(ji)充(chong)分吸收內層(ceng)(ceng)滾(gun)筒(tong)(tong)(tong)散(san)發的(de)熱(re)量，又(you)(you)吸收中(zhong)(zhong)層(ceng)(ceng)滾(gun)筒(tong)(tong)(tong)的(de)熱(re)量，同(tong)時又(you)(you)延(yan)長了干(gan)(gan)燥(zao)(zao)(zao)時間，物(wu)料(liao)在(zai)(zai)此(ci)達到(dao)干(gan)(gan)燥(zao)(zao)(zao)狀態。物(wu)料(liao)行(xing)(xing)(xing)至中(zhong)(zhong)層(ceng)(ceng)另(ling)一端(duan)而落入(ru)外(wai)層(ceng)(ceng)，物(wu)料(liao)在(zai)(zai)外(wai)層(ceng)(ceng)滾(gun)筒(tong)(tong)(tong)內呈(cheng)矩形(xing)多回路方式行(xing)(xing)(xing)進，達到(dao)干(gan)(gan)燥(zao)(zao)(zao)效果(guo)的(de)物(wu)料(liao)在(zai)(zai)熱(re)風作(zuo)用下快(kuai)速行(xing)(xing)(xing)進排出滾(gun)筒(tong)(tong)(tong)，沒有達到(dao)干(gan)(gan)燥(zao)(zao)(zao)效果(guo)的(de)濕物(wu)料(liao)因(yin)自重而不(bu)能快(kuai)速行(xing)(xing)(xing)進，物(wu)料(liao)在(zai)(zai)此(ci)矩形(xing)抄(chao)板(ban)內進行(xing)(xing)(xing)充(chong)分干(gan)(gan)燥(zao)(zao)(zao)，由(you)此(ci)完成干(gan)(gan)燥(zao)(zao)(zao)目的(de)。
