產品概況(kuang)
回轉式三筒烘干機改進原單筒烘干機內部結構，增加入機前濕料的預烘干和延長濕料在機內烘干時間，再加上密封、保溫以及合理的配套措施，使烘干機生產能力與原單筒式烘干機相比，提高48-80%，單位容積蒸發強度可達120-180kg/m3，標準煤耗僅為6-8kg/t。其技術先進、運行參數合理，操作簡單可行，廣泛應用于各個行業的礦渣、粘土、煤。
產品結構(gou)
三(san)筒(tong)式烘(hong)干(gan)機(ji)是通過(guo)對單筒(tong)烘(hong)干(gan)機(ji)的(de)單筒(tong)體改為(wei)套疊(die)在一起的(de)三(san)筒(tong)，以縮短烘(hong)干(gan)機(ji)體的(de)外(wai)形尺寸。該機(ji)工作時(shi)，物料和熱氣流依次進入(ru)內至外(wai)筒(tong)體，在機(ji)體Z形往復折(zhe)流后，充分利用熱能烘(hong)干(gan)物料后再卸出。
烘干機(ji)筒(tong)體部(bu)分由三個同(tong)軸水平放置的(de)內、中、外筒(tong)套疊組成(cheng)，這(zhe)就使筒(tong)體的(de)截面得到充分的(de)利用。其筒(tong)體外形總長(chang)度約(yue)為與之(zhi)相當的(de)單筒(tong)的(de)30-35%。從而大幅度地(di)減少占地(di)面積和廠房(fang)建筑面積。
該(gai)機的支(zhi)(zhi)承裝置，是(shi)在外筒上輪(lun)帶與托(tuo)輪(lun)支(zhi)(zhi)承，由電機直接(jie)帶動托(tuo)輪(lun)。通(tong)過托(tuo)輪(lun)與輪(lun)帶摩擦，使(shi)筒體轉動。該(gai)機總體結構緊湊、合(he)理、簡單(dan)，為便(bian)于(yu)磨損件的檢修更(geng)換，在中間設計成軸向剖分式，用螺(luo)栓固(gu)定(ding)連接(jie)。
工作(zuo)原理
物(wu)(wu)(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)由供(gong)料(liao)(liao)(liao)裝(zhuang)置進(jin)(jin)入(ru)回(hui)轉滾(gun)(gun)(gun)筒(tong)(tong)的(de)內層(ceng)(ceng),實現(xian)順流烘干,物(wu)(wu)(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)內層(ceng)(ceng)的(de)抄(chao)板下(xia)不(bu)斷抄(chao)起、散落呈(cheng)螺旋行(xing)進(jin)(jin)式實現(xian)熱(re)交換，物(wu)(wu)(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)移(yi)動(dong)至內層(ceng)(ceng)的(de)另一(yi)端(duan)進(jin)(jin)入(ru)中(zhong)層(ceng)(ceng)，進(jin)(jin)行(xing)逆流烘干，物(wu)(wu)(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)中(zhong)層(ceng)(ceng)不(bu)斷地被(bei)反復揚進(jin)(jin)，呈(cheng)進(jin)(jin)兩(liang)步(bu)退一(yi)步(bu)的(de)行(xing)進(jin)(jin)方式，物(wu)(wu)(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)中(zhong)層(ceng)(ceng)既(ji)充分吸(xi)收內層(ceng)(ceng)滾(gun)(gun)(gun)筒(tong)(tong)散發的(de)熱(re)量，又吸(xi)收中(zhong)層(ceng)(ceng)滾(gun)(gun)(gun)筒(tong)(tong)的(de)熱(re)量，同(tong)時(shi)又延長(chang)了干燥(zao)(zao)(zao)時(shi)間(jian)，物(wu)(wu)(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)此達到(dao)干燥(zao)(zao)(zao)狀態。物(wu)(wu)(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)行(xing)至中(zhong)層(ceng)(ceng)另一(yi)端(duan)而落入(ru)外層(ceng)(ceng)，物(wu)(wu)(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)外層(ceng)(ceng)滾(gun)(gun)(gun)筒(tong)(tong)內呈(cheng)矩形(xing)多回(hui)路方式行(xing)進(jin)(jin)，達到(dao)干燥(zao)(zao)(zao)效果(guo)的(de)物(wu)(wu)(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)熱(re)風作用下(xia)快速行(xing)進(jin)(jin)排(pai)出滾(gun)(gun)(gun)筒(tong)(tong)，沒(mei)有達到(dao)干燥(zao)(zao)(zao)效果(guo)的(de)濕物(wu)(wu)(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)因自重而不(bu)能快速行(xing)進(jin)(jin)，物(wu)(wu)(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)此矩形(xing)抄(chao)板內進(jin)(jin)行(xing)充分干燥(zao)(zao)(zao)，由此完成干燥(zao)(zao)(zao)目的(de)。
