產品(pin)概況
回轉式(shi)三筒(tong)(tong)烘(hong)干(gan)機(ji)改進(jin)原單(dan)筒(tong)(tong)烘(hong)干(gan)機(ji)內(nei)部(bu)結構，增加入機(ji)前(qian)濕(shi)料(liao)的預烘(hong)干(gan)和延長濕(shi)料(liao)在機(ji)內(nei)烘(hong)干(gan)時間，再(zai)加上密封、保(bao)溫以及合(he)理的配套措(cuo)施，使(shi)烘(hong)干(gan)機(ji)生產(chan)能(neng)力與原單(dan)筒(tong)(tong)式(shi)烘(hong)干(gan)機(ji)相比，提(ti)高48-80%，單(dan)位容積蒸發強度可達120-180kg/m3，標準煤耗僅(jin)為6-8kg/t。其技術先(xian)進(jin)、運行(xing)參數合(he)理，操(cao)作簡單(dan)可行(xing)，廣泛應用于各(ge)個行(xing)業的礦渣、粘土、煤。
產品結構
三筒烘干(gan)機是通(tong)過(guo)對單筒烘干(gan)機的單筒體改為套疊在一起的三筒，以縮短(duan)烘干(gan)機體的外(wai)形尺寸。該機工作時，物(wu)料(liao)和熱氣(qi)流依次進入內至(zhi)外(wai)筒體，在機體Z形往復折流后，充分利用熱能烘干(gan)物(wu)料(liao)后再卸出(chu)。
烘干機筒(tong)體部分由三個同軸水(shui)平放置的(de)(de)內、中、外筒(tong)套疊組成，這就使筒(tong)體的(de)(de)截(jie)面得到(dao)充分的(de)(de)利用(yong)。其筒(tong)體外形(xing)總(zong)長(chang)度約為與之相當的(de)(de)單筒(tong)的(de)(de)30-35%。從(cong)而大幅(fu)度地減(jian)少占地面積和廠(chang)房建筑面積。
該機的支(zhi)承裝(zhuang)置，是在(zai)外(wai)筒(tong)上輪(lun)(lun)帶(dai)與(yu)托(tuo)輪(lun)(lun)支(zhi)承，由電機直接(jie)帶(dai)動(dong)托(tuo)輪(lun)(lun)。通(tong)過托(tuo)輪(lun)(lun)與(yu)輪(lun)(lun)帶(dai)摩(mo)擦，使筒(tong)體轉動(dong)。該機總體結構緊湊、合理、簡單(dan)，為便于磨損件(jian)的檢修更換，在(zai)中間(jian)設計成軸向剖分式(shi)，用螺栓固定(ding)連接(jie)。
