產(chan)品概況
回轉式三筒(tong)烘(hong)(hong)(hong)干(gan)機改進(jin)原(yuan)(yuan)單筒(tong)烘(hong)(hong)(hong)干(gan)機內部結構，增加入機前濕(shi)料(liao)的預烘(hong)(hong)(hong)干(gan)和(he)延長濕(shi)料(liao)在機內烘(hong)(hong)(hong)干(gan)時(shi)間，再加上密封、保溫以(yi)及合理的配(pei)套措施(shi)，使烘(hong)(hong)(hong)干(gan)機生(sheng)產能力與原(yuan)(yuan)單筒(tong)式烘(hong)(hong)(hong)干(gan)機相(xiang)比，提高48-80%，單位容(rong)積蒸發強度可達120-180kg/m3，標準(zhun)煤耗(hao)僅為6-8kg/t。其技術先進(jin)、運(yun)行(xing)參數合理，操作簡單可行(xing)，廣泛應用于各個行(xing)業的礦渣、粘土、煤。
產品結構(gou)
三(san)筒(tong)烘干機(ji)是通過對單筒(tong)烘干機(ji)的單筒(tong)體改為套疊在一起的三(san)筒(tong)，以縮(suo)短烘干機(ji)體的外(wai)形(xing)尺寸。該機(ji)工作時，物料和(he)熱氣流(liu)依次進入內至外(wai)筒(tong)體，在機(ji)體Z形(xing)往(wang)復折流(liu)后，充分利用熱能(neng)烘干物料后再(zai)卸出。
烘(hong)干機(ji)筒體部分由三(san)個同軸水平放置的內、中、外筒套(tao)疊組成，這就(jiu)使筒體的截面得到充分的利用。其(qi)筒體外形總長度約為(wei)與之(zhi)相當的單筒的30-35%。從而大幅度地(di)減(jian)少占(zhan)地(di)面積和廠(chang)房建筑面積。
該(gai)機的(de)支承(cheng)(cheng)裝置，是在外筒上輪帶與托輪支承(cheng)(cheng)，由(you)電(dian)機直接帶動托輪。通過托輪與輪帶摩擦，使筒體轉動。該(gai)機總體結構緊湊、合理、簡單(dan)，為(wei)便于(yu)磨損件的(de)檢(jian)修(xiu)更換(huan)，在中間(jian)設計(ji)成(cheng)軸向剖分式，用螺栓固定連(lian)接。
