產(chan)品(pin)概況(kuang)
回轉式三筒烘(hong)(hong)(hong)干(gan)機(ji)改進(jin)原單筒烘(hong)(hong)(hong)干(gan)機(ji)內(nei)部結構(gou)，增(zeng)加(jia)(jia)入機(ji)前(qian)濕(shi)料(liao)的(de)預烘(hong)(hong)(hong)干(gan)和延長濕(shi)料(liao)在(zai)機(ji)內(nei)烘(hong)(hong)(hong)干(gan)時間(jian)，再加(jia)(jia)上密封(feng)、保溫以及合(he)理的(de)配套措施，使烘(hong)(hong)(hong)干(gan)機(ji)生產能力與原單筒式烘(hong)(hong)(hong)干(gan)機(ji)相比，提高48-80%，單位容(rong)積蒸發強度(du)可(ke)達120-180kg/m3，標準煤(mei)耗僅(jin)為6-8kg/t。其技術先(xian)進(jin)、運行(xing)參(can)數合(he)理，操作簡單可(ke)行(xing)，廣泛(fan)應(ying)用于各(ge)個行(xing)業(ye)的(de)礦渣、粘土、煤(mei)。
產品結構
三筒(tong)烘(hong)(hong)干機(ji)(ji)是通過對(dui)單(dan)筒(tong)烘(hong)(hong)干機(ji)(ji)的單(dan)筒(tong)體(ti)改為套(tao)疊(die)在一起的三筒(tong)，以縮短烘(hong)(hong)干機(ji)(ji)體(ti)的外形尺寸。該機(ji)(ji)工作時(shi)，物(wu)料和熱氣流依(yi)次進入內至外筒(tong)體(ti)，在機(ji)(ji)體(ti)Z形往(wang)復折流后，充(chong)分(fen)利用(yong)熱能烘(hong)(hong)干物(wu)料后再(zai)卸出。
烘干機筒(tong)(tong)體(ti)(ti)部分由三個同軸(zhou)水平放置的內、中、外(wai)筒(tong)(tong)套疊組(zu)成，這就使筒(tong)(tong)體(ti)(ti)的截面(mian)得到充分的利用。其筒(tong)(tong)體(ti)(ti)外(wai)形總長度(du)約(yue)為與之相當的單(dan)筒(tong)(tong)的30-35%。從(cong)而大幅度(du)地減少占地面(mian)積(ji)和廠(chang)房建筑面(mian)積(ji)。
該機的支承(cheng)裝(zhuang)置(zhi)，是(shi)在外筒(tong)上輪帶與托輪支承(cheng)，由(you)電機直接帶動(dong)托輪。通過托輪與輪帶摩(mo)擦(ca)，使筒(tong)體轉動(dong)。該機總體結構緊湊、合(he)理、簡單，為(wei)便于磨損件(jian)的檢修更換，在中間設計成軸向剖分式，用螺栓固(gu)定連接。
工作(zuo)原理(li)
