產品概況
回轉(zhuan)式三筒烘(hong)(hong)(hong)干機(ji)(ji)(ji)(ji)改進(jin)原單(dan)筒烘(hong)(hong)(hong)干機(ji)(ji)(ji)(ji)內部結構，增加(jia)入機(ji)(ji)(ji)(ji)前濕(shi)料(liao)的預(yu)烘(hong)(hong)(hong)干和延長濕(shi)料(liao)在機(ji)(ji)(ji)(ji)內烘(hong)(hong)(hong)干時間，再加(jia)上密封、保溫以及合(he)理(li)的配套(tao)措施，使烘(hong)(hong)(hong)干機(ji)(ji)(ji)(ji)生產(chan)能力與原單(dan)筒式烘(hong)(hong)(hong)干機(ji)(ji)(ji)(ji)相比，提高48-80%，單(dan)位容積(ji)蒸發強(qiang)度可(ke)達120-180kg/m3，標準煤(mei)(mei)耗僅為(wei)6-8kg/t。其技術先進(jin)、運行參數合(he)理(li)，操(cao)作簡單(dan)可(ke)行，廣泛應用于各個行業的礦渣、粘土、煤(mei)(mei)。
產(chan)品結構
三筒(tong)(tong)烘(hong)干(gan)機(ji)(ji)是(shi)通過對(dui)單筒(tong)(tong)烘(hong)干(gan)機(ji)(ji)的單筒(tong)(tong)體改為套疊在(zai)一起的三筒(tong)(tong)，以縮短(duan)烘(hong)干(gan)機(ji)(ji)體的外形尺寸。該機(ji)(ji)工作時，物(wu)(wu)料和熱(re)氣流依次進入內至外筒(tong)(tong)體，在(zai)機(ji)(ji)體Z形往復折流后，充分利(li)用熱(re)能(neng)烘(hong)干(gan)物(wu)(wu)料后再(zai)卸(xie)出。
烘(hong)干機(ji)筒(tong)體部分由三個(ge)同軸水平放置(zhi)的(de)內、中、外(wai)筒(tong)套疊組成，這就(jiu)使筒(tong)體的(de)截面(mian)得到(dao)充分的(de)利用。其筒(tong)體外(wai)形總(zong)長度(du)約為(wei)與之(zhi)相(xiang)當的(de)單筒(tong)的(de)30-35%。從(cong)而(er)大幅(fu)度(du)地減少占地面(mian)積和廠房建筑面(mian)積。
該(gai)機的支(zhi)承裝置，是在(zai)外筒(tong)(tong)上輪(lun)(lun)帶(dai)與托(tuo)(tuo)輪(lun)(lun)支(zhi)承，由電機直接帶(dai)動(dong)托(tuo)(tuo)輪(lun)(lun)。通過托(tuo)(tuo)輪(lun)(lun)與輪(lun)(lun)帶(dai)摩擦(ca)，使筒(tong)(tong)體轉動(dong)。該(gai)機總體結構緊湊、合理、簡(jian)單，為便于磨損件的檢(jian)修更換，在(zai)中間設計成軸(zhou)向剖分式，用螺(luo)栓(shuan)固定連接。
工作原(yuan)理
物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)由(you)供料(liao)(liao)(liao)裝置進(jin)(jin)(jin)(jin)(jin)入回轉滾筒(tong)的(de)內(nei)(nei)層(ceng)(ceng)(ceng),實(shi)現(xian)(xian)順流烘(hong)干(gan),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)內(nei)(nei)層(ceng)(ceng)(ceng)的(de)抄板下(xia)不斷(duan)(duan)抄起、散落呈螺旋行(xing)(xing)進(jin)(jin)(jin)(jin)(jin)式實(shi)現(xian)(xian)熱(re)交(jiao)換，物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)移動至(zhi)(zhi)內(nei)(nei)層(ceng)(ceng)(ceng)的(de)另一端進(jin)(jin)(jin)(jin)(jin)入中層(ceng)(ceng)(ceng)，進(jin)(jin)(jin)(jin)(jin)行(xing)(xing)逆流烘(hong)干(gan)，物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)中層(ceng)(ceng)(ceng)不斷(duan)(duan)地被反復揚進(jin)(jin)(jin)(jin)(jin)，呈進(jin)(jin)(jin)(jin)(jin)兩(liang)步退一步的(de)行(xing)(xing)進(jin)(jin)(jin)(jin)(jin)方式，物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)中層(ceng)(ceng)(ceng)既充分吸收(shou)內(nei)(nei)層(ceng)(ceng)(ceng)滾筒(tong)散發的(de)熱(re)量，又吸收(shou)中層(ceng)(ceng)(ceng)滾筒(tong)的(de)熱(re)量，同時又延長了干(gan)燥時間，物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)此達到(dao)(dao)干(gan)燥狀態。物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)行(xing)(xing)至(zhi)(zhi)中層(ceng)(ceng)(ceng)另一端而落入外(wai)層(ceng)(ceng)(ceng)，物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)外(wai)層(ceng)(ceng)(ceng)滾筒(tong)內(nei)(nei)呈矩形(xing)多回路(lu)方式行(xing)(xing)進(jin)(jin)(jin)(jin)(jin)，達到(dao)(dao)干(gan)燥效果的(de)物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)熱(re)風作用(yong)下(xia)快(kuai)(kuai)速行(xing)(xing)進(jin)(jin)(jin)(jin)(jin)排出滾筒(tong)，沒有(you)達到(dao)(dao)干(gan)燥效果的(de)濕物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)因自(zi)重而不能(neng)快(kuai)(kuai)速行(xing)(xing)進(jin)(jin)(jin)(jin)(jin)，物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)此矩形(xing)抄板內(nei)(nei)進(jin)(jin)(jin)(jin)(jin)行(xing)(xing)充分干(gan)燥，由(you)此完成(cheng)干(gan)燥目的(de)。
