產品概況
回(hui)轉式三筒烘(hong)干機(ji)改進原(yuan)單(dan)筒烘(hong)干機(ji)內部結(jie)構，增加入(ru)機(ji)前(qian)濕料的預(yu)烘(hong)干和延長(chang)濕料在機(ji)內烘(hong)干時間，再加上密封、保溫以及合理的配套(tao)措施，使(shi)烘(hong)干機(ji)生產能力(li)與原(yuan)單(dan)筒式烘(hong)干機(ji)相(xiang)比(bi)，提高48-80%，單(dan)位容(rong)積蒸發強度可達120-180kg/m3，標準煤耗僅為6-8kg/t。其技術(shu)先進、運行(xing)(xing)參數合理，操作簡(jian)單(dan)可行(xing)(xing)，廣泛應用(yong)于各個(ge)行(xing)(xing)業的礦渣(zha)、粘土、煤。
產品結(jie)構
三(san)筒(tong)(tong)烘干(gan)(gan)機(ji)是(shi)通過(guo)對(dui)單筒(tong)(tong)烘干(gan)(gan)機(ji)的(de)單筒(tong)(tong)體(ti)改(gai)為(wei)套(tao)疊(die)在(zai)一起的(de)三(san)筒(tong)(tong)，以縮短烘干(gan)(gan)機(ji)體(ti)的(de)外形(xing)尺寸。該機(ji)工作時，物料(liao)和熱(re)(re)氣流依次進入內至外筒(tong)(tong)體(ti)，在(zai)機(ji)體(ti)Z形(xing)往復折流后，充分利(li)用熱(re)(re)能烘干(gan)(gan)物料(liao)后再卸出。
烘(hong)干機筒(tong)(tong)體部(bu)分(fen)由三個(ge)同(tong)軸水平放(fang)置的(de)內、中、外筒(tong)(tong)套疊組成，這(zhe)就使筒(tong)(tong)體的(de)截面(mian)(mian)得到充分(fen)的(de)利用(yong)。其筒(tong)(tong)體外形總長度約為與之(zhi)相當的(de)單筒(tong)(tong)的(de)30-35%。從而大幅(fu)度地減少占地面(mian)(mian)積和廠房建筑(zhu)面(mian)(mian)積。
該機(ji)的(de)(de)支(zhi)承裝置，是在外筒上輪帶與(yu)托(tuo)輪支(zhi)承，由電機(ji)直接(jie)帶動(dong)(dong)托(tuo)輪。通過托(tuo)輪與(yu)輪帶摩擦(ca)，使筒體轉動(dong)(dong)。該機(ji)總(zong)體結(jie)構緊湊、合理、簡(jian)單(dan)，為便于磨損(sun)件的(de)(de)檢修更(geng)換，在中間設計成軸向剖(pou)分式，用(yong)螺栓固定連接(jie)。
工作(zuo)原理
物(wu)(wu)料(liao)(liao)由供料(liao)(liao)裝(zhuang)置進(jin)(jin)入(ru)(ru)回(hui)轉(zhuan)滾(gun)筒(tong)(tong)的(de)內(nei)層(ceng)(ceng)(ceng),實(shi)現順流烘干,物(wu)(wu)料(liao)(liao)在(zai)(zai)內(nei)層(ceng)(ceng)(ceng)的(de)抄(chao)板下不斷抄(chao)起、散落(luo)(luo)呈螺旋行進(jin)(jin)式(shi)實(shi)現熱(re)交換，物(wu)(wu)料(liao)(liao)移動(dong)至(zhi)(zhi)內(nei)層(ceng)(ceng)(ceng)的(de)另一端(duan)進(jin)(jin)入(ru)(ru)中(zhong)(zhong)層(ceng)(ceng)(ceng)，進(jin)(jin)行逆流烘干，物(wu)(wu)料(liao)(liao)在(zai)(zai)中(zhong)(zhong)層(ceng)(ceng)(ceng)不斷地(di)被(bei)反復(fu)揚(yang)進(jin)(jin)，呈進(jin)(jin)兩(liang)步退一步的(de)行進(jin)(jin)方式(shi)，物(wu)(wu)料(liao)(liao)在(zai)(zai)中(zhong)(zhong)層(ceng)(ceng)(ceng)既充分(fen)吸收(shou)內(nei)層(ceng)(ceng)(ceng)滾(gun)筒(tong)(tong)散發的(de)熱(re)量，又吸收(shou)中(zhong)(zhong)層(ceng)(ceng)(ceng)滾(gun)筒(tong)(tong)的(de)熱(re)量，同時(shi)又延長了干燥(zao)(zao)時(shi)間(jian)，物(wu)(wu)料(liao)(liao)在(zai)(zai)此達到(dao)干燥(zao)(zao)狀(zhuang)態(tai)。物(wu)(wu)料(liao)(liao)行至(zhi)(zhi)中(zhong)(zhong)層(ceng)(ceng)(ceng)另一端(duan)而(er)落(luo)(luo)入(ru)(ru)外層(ceng)(ceng)(ceng)，物(wu)(wu)料(liao)(liao)在(zai)(zai)外層(ceng)(ceng)(ceng)滾(gun)筒(tong)(tong)內(nei)呈矩(ju)形多(duo)回(hui)路方式(shi)行進(jin)(jin)，達到(dao)干燥(zao)(zao)效果(guo)的(de)物(wu)(wu)料(liao)(liao)在(zai)(zai)熱(re)風作用下快速行進(jin)(jin)排出滾(gun)筒(tong)(tong)，沒(mei)有達到(dao)干燥(zao)(zao)效果(guo)的(de)濕(shi)物(wu)(wu)料(liao)(liao)因自重而(er)不能快速行進(jin)(jin)，物(wu)(wu)料(liao)(liao)在(zai)(zai)此矩(ju)形抄(chao)板內(nei)進(jin)(jin)行充分(fen)干燥(zao)(zao)，由此完成干燥(zao)(zao)目的(de)。
