產(chan)品概況
回轉(zhuan)式(shi)三筒(tong)(tong)烘(hong)(hong)(hong)干(gan)機改進(jin)原單(dan)筒(tong)(tong)烘(hong)(hong)(hong)干(gan)機內部結構，增加(jia)(jia)入機前濕料的預烘(hong)(hong)(hong)干(gan)和(he)延長濕料在(zai)機內烘(hong)(hong)(hong)干(gan)時間，再加(jia)(jia)上(shang)密封、保溫以及合理的配套措施(shi)，使烘(hong)(hong)(hong)干(gan)機生產能(neng)力與原單(dan)筒(tong)(tong)式(shi)烘(hong)(hong)(hong)干(gan)機相比(bi)，提高48-80%，單(dan)位(wei)容積蒸發強度可達(da)120-180kg/m3，標準(zhun)煤(mei)耗(hao)僅為6-8kg/t。其(qi)技術(shu)先進(jin)、運行參數合理，操作簡(jian)單(dan)可行，廣(guang)泛應用于各個行業的礦渣(zha)、粘土、煤(mei)。
產品結(jie)構
三筒(tong)(tong)烘(hong)干機是通過對(dui)單(dan)筒(tong)(tong)烘(hong)干機的單(dan)筒(tong)(tong)體改為套疊(die)在(zai)一起的三筒(tong)(tong)，以縮短烘(hong)干機體的外(wai)形(xing)尺寸。該機工作(zuo)時，物(wu)料和熱氣流(liu)依次進入內(nei)至外(wai)筒(tong)(tong)體，在(zai)機體Z形(xing)往復折流(liu)后，充分(fen)利用熱能烘(hong)干物(wu)料后再卸出。
烘干機(ji)筒(tong)(tong)體(ti)部(bu)分由三個同軸水平放(fang)置的(de)內(nei)、中、外(wai)筒(tong)(tong)套疊組成，這(zhe)就使(shi)筒(tong)(tong)體(ti)的(de)截面(mian)得到充分的(de)利用。其(qi)筒(tong)(tong)體(ti)外(wai)形總長度(du)(du)約(yue)為與(yu)之相當(dang)的(de)單筒(tong)(tong)的(de)30-35%。從而大幅度(du)(du)地減(jian)少(shao)占(zhan)地面(mian)積(ji)和廠房(fang)建筑面(mian)積(ji)。
該機(ji)的支(zhi)(zhi)承裝置，是在外筒上(shang)輪帶(dai)與(yu)托(tuo)輪支(zhi)(zhi)承，由電機(ji)直接帶(dai)動(dong)托(tuo)輪。通過托(tuo)輪與(yu)輪帶(dai)摩擦，使筒體(ti)轉動(dong)。該機(ji)總體(ti)結構緊湊、合理、簡單(dan)，為便于磨損件的檢修更換，在中間設計成軸向剖分(fen)式，用螺栓固定連接。
工作原理(li)
物(wu)(wu)料(liao)(liao)由供料(liao)(liao)裝置進(jin)入回(hui)轉滾(gun)筒的內(nei)層(ceng),實現順流烘干(gan)(gan)(gan),物(wu)(wu)料(liao)(liao)在內(nei)層(ceng)的抄(chao)(chao)板下不斷抄(chao)(chao)起、散落(luo)呈螺旋行(xing)(xing)進(jin)式(shi)實現熱交換(huan)，物(wu)(wu)料(liao)(liao)移動至(zhi)內(nei)層(ceng)的另(ling)一端進(jin)入中(zhong)層(ceng)，進(jin)行(xing)(xing)逆流烘干(gan)(gan)(gan)，物(wu)(wu)料(liao)(liao)在中(zhong)層(ceng)不斷地被反復揚(yang)進(jin)，呈進(jin)兩步(bu)退一步(bu)的行(xing)(xing)進(jin)方(fang)式(shi)，物(wu)(wu)料(liao)(liao)在中(zhong)層(ceng)既(ji)充(chong)分(fen)(fen)吸收內(nei)層(ceng)滾(gun)筒散發的熱量(liang)，又吸收中(zhong)層(ceng)滾(gun)筒的熱量(liang)，同時(shi)(shi)又延(yan)長(chang)了干(gan)(gan)(gan)燥(zao)時(shi)(shi)間，物(wu)(wu)料(liao)(liao)在此達到干(gan)(gan)(gan)燥(zao)狀態。物(wu)(wu)料(liao)(liao)行(xing)(xing)至(zhi)中(zhong)層(ceng)另(ling)一端而(er)落(luo)入外層(ceng)，物(wu)(wu)料(liao)(liao)在外層(ceng)滾(gun)筒內(nei)呈矩形多回(hui)路(lu)方(fang)式(shi)行(xing)(xing)進(jin)，達到干(gan)(gan)(gan)燥(zao)效果(guo)的物(wu)(wu)料(liao)(liao)在熱風作用(yong)下快(kuai)速(su)行(xing)(xing)進(jin)排(pai)出滾(gun)筒，沒有(you)達到干(gan)(gan)(gan)燥(zao)效果(guo)的濕物(wu)(wu)料(liao)(liao)因自重而(er)不能(neng)快(kuai)速(su)行(xing)(xing)進(jin)，物(wu)(wu)料(liao)(liao)在此矩形抄(chao)(chao)板內(nei)進(jin)行(xing)(xing)充(chong)分(fen)(fen)干(gan)(gan)(gan)燥(zao)，由此完成干(gan)(gan)(gan)燥(zao)目的。
