產(chan)品(pin)概(gai)況
回(hui)轉式(shi)三(san)筒烘干機改進(jin)(jin)原單筒烘干機內(nei)(nei)部(bu)結構，增加(jia)入機前(qian)濕(shi)料的預烘干和延長(chang)濕(shi)料在機內(nei)(nei)烘干時間(jian)，再加(jia)上密封(feng)、保溫以及合理的配套措施，使烘干機生產能力與原單筒式(shi)烘干機相比(bi)，提高48-80%，單位(wei)容(rong)積蒸發強(qiang)度可(ke)(ke)達120-180kg/m3，標準煤(mei)耗僅為6-8kg/t。其技(ji)術先進(jin)(jin)、運行(xing)參(can)數(shu)合理，操作(zuo)簡單可(ke)(ke)行(xing)，廣泛應用于各個行(xing)業的礦渣(zha)、粘土、煤(mei)。
產品結構
三筒(tong)烘(hong)(hong)干機(ji)是通過對單筒(tong)烘(hong)(hong)干機(ji)的單筒(tong)體改為套疊(die)在一起的三筒(tong)，以縮短烘(hong)(hong)干機(ji)體的外形(xing)尺寸。該機(ji)工(gong)作時，物料和熱氣流依(yi)次進(jin)入內至外筒(tong)體，在機(ji)體Z形(xing)往復折流后(hou)，充(chong)分利用熱能烘(hong)(hong)干物料后(hou)再(zai)卸出。
烘干機筒(tong)體(ti)(ti)部分由(you)三個同軸水平放置的(de)(de)內、中(zhong)、外(wai)筒(tong)套(tao)疊組成，這(zhe)就使筒(tong)體(ti)(ti)的(de)(de)截面(mian)得到充分的(de)(de)利用。其筒(tong)體(ti)(ti)外(wai)形總長度約為與之相當的(de)(de)單筒(tong)的(de)(de)30-35%。從而大(da)幅度地減(jian)少(shao)占(zhan)地面(mian)積和廠房建筑面(mian)積。
該機的支(zhi)(zhi)承裝(zhuang)置，是在(zai)外筒上輪帶與(yu)托(tuo)輪支(zhi)(zhi)承，由(you)電機直接帶動托(tuo)輪。通過托(tuo)輪與(yu)輪帶摩(mo)擦，使筒體轉動。該機總體結構緊(jin)湊、合理(li)、簡單，為便于磨損(sun)件(jian)的檢修更換，在(zai)中間設計成軸向(xiang)剖分式，用螺栓固定連接。
工作原理
