產品概況(kuang)
回轉式三筒烘干(gan)機(ji)改(gai)進原單筒烘干(gan)機(ji)內部結(jie)構(gou)，增加入機(ji)前濕料(liao)的預烘干(gan)和延長濕料(liao)在機(ji)內烘干(gan)時間，再加上密封、保(bao)溫以(yi)及合(he)理的配套措施(shi)，使烘干(gan)機(ji)生產(chan)能力與(yu)原單筒式烘干(gan)機(ji)相比(bi)，提(ti)高48-80%，單位容積蒸發(fa)強度可達(da)120-180kg/m3，標準煤耗僅為6-8kg/t。其技術先進、運行(xing)參數合(he)理，操(cao)作簡單可行(xing)，廣泛應用于各個行(xing)業的礦渣、粘土、煤。
產品(pin)結構
三筒(tong)烘(hong)(hong)干(gan)機是通過對(dui)單筒(tong)烘(hong)(hong)干(gan)機的單筒(tong)體(ti)改為(wei)套疊(die)在一起的三筒(tong)，以縮短烘(hong)(hong)干(gan)機體(ti)的外(wai)(wai)形(xing)尺寸。該機工(gong)作時，物料和熱氣流依次進入內(nei)至外(wai)(wai)筒(tong)體(ti)，在機體(ti)Z形(xing)往(wang)復折流后，充分利用(yong)熱能烘(hong)(hong)干(gan)物料后再卸出。
烘干機筒(tong)體(ti)(ti)部分由三個同軸水平放置的(de)(de)內、中、外(wai)筒(tong)套(tao)疊組成，這就使筒(tong)體(ti)(ti)的(de)(de)截面(mian)得到充分的(de)(de)利用。其(qi)筒(tong)體(ti)(ti)外(wai)形總長度(du)約為與之相當的(de)(de)單筒(tong)的(de)(de)30-35%。從而大幅度(du)地減少占地面(mian)積和(he)廠(chang)房建筑面(mian)積。
該機(ji)(ji)的支承裝置，是在外筒上輪(lun)帶與托輪(lun)支承，由電機(ji)(ji)直接帶動托輪(lun)。通過托輪(lun)與輪(lun)帶摩(mo)擦，使筒體轉動。該機(ji)(ji)總體結構緊湊、合理、簡單(dan)，為便于(yu)磨損件的檢修(xiu)更(geng)換，在中間設計成軸向剖分式，用螺栓固定(ding)連接。
