產品概(gai)況
回轉式三筒烘(hong)(hong)(hong)干(gan)機(ji)改進原單筒烘(hong)(hong)(hong)干(gan)機(ji)內部結構，增(zeng)加(jia)入機(ji)前濕料的(de)預烘(hong)(hong)(hong)干(gan)和延長(chang)濕料在機(ji)內烘(hong)(hong)(hong)干(gan)時(shi)間，再(zai)加(jia)上密封、保溫以(yi)及合理(li)的(de)配套措施(shi)，使(shi)烘(hong)(hong)(hong)干(gan)機(ji)生(sheng)產能力與原單筒式烘(hong)(hong)(hong)干(gan)機(ji)相比，提高(gao)48-80%，單位容(rong)積蒸(zheng)發強(qiang)度可達(da)120-180kg/m3，標準煤耗僅為6-8kg/t。其技(ji)術先進、運行(xing)參數合理(li)，操作簡(jian)單可行(xing)，廣泛應用(yong)于(yu)各個(ge)行(xing)業的(de)礦渣、粘(zhan)土(tu)、煤。
產品結構(gou)
三(san)筒(tong)烘干機(ji)是通過對(dui)單筒(tong)烘干機(ji)的單筒(tong)體改為套疊在一起的三(san)筒(tong)，以縮短烘干機(ji)體的外形尺寸。該機(ji)工(gong)作時，物料和熱氣流(liu)依次進入內至外筒(tong)體，在機(ji)體Z形往復折流(liu)后(hou)，充分利(li)用熱能(neng)烘干物料后(hou)再卸出(chu)。
烘干機筒(tong)體(ti)部分由三個同軸水(shui)平放置的(de)內、中、外(wai)筒(tong)套疊組(zu)成(cheng)，這就使筒(tong)體(ti)的(de)截面得(de)到充分的(de)利用。其(qi)筒(tong)體(ti)外(wai)形總長度(du)約為與(yu)之相(xiang)當的(de)單(dan)筒(tong)的(de)30-35%。從而(er)大幅度(du)地減少占地面積和廠房建筑面積。
該機的(de)支承裝置，是在外筒上輪(lun)帶與托(tuo)輪(lun)支承，由電機直接帶動(dong)托(tuo)輪(lun)。通過托(tuo)輪(lun)與輪(lun)帶摩擦，使筒體轉動(dong)。該機總體結(jie)構(gou)緊湊、合理(li)、簡單，為(wei)便于磨(mo)損(sun)件(jian)的(de)檢修(xiu)更換，在中間設計(ji)成(cheng)軸向剖(pou)分式，用螺栓(shuan)固定連(lian)接。
工(gong)作原理
物(wu)(wu)料(liao)由供料(liao)裝置進(jin)入回轉滾筒(tong)的(de)(de)內層(ceng)(ceng)(ceng)(ceng),實現順流烘干,物(wu)(wu)料(liao)在(zai)(zai)(zai)內層(ceng)(ceng)(ceng)(ceng)的(de)(de)抄(chao)板(ban)下不斷(duan)抄(chao)起(qi)、散(san)落(luo)呈(cheng)螺旋行(xing)進(jin)式(shi)(shi)實現熱(re)交換，物(wu)(wu)料(liao)移動至內層(ceng)(ceng)(ceng)(ceng)的(de)(de)另(ling)一端進(jin)入中層(ceng)(ceng)(ceng)(ceng)，進(jin)行(xing)逆流烘干，物(wu)(wu)料(liao)在(zai)(zai)(zai)中層(ceng)(ceng)(ceng)(ceng)不斷(duan)地被反(fan)復揚進(jin)，呈(cheng)進(jin)兩步退一步的(de)(de)行(xing)進(jin)方(fang)式(shi)(shi)，物(wu)(wu)料(liao)在(zai)(zai)(zai)中層(ceng)(ceng)(ceng)(ceng)既充(chong)(chong)分吸(xi)收內層(ceng)(ceng)(ceng)(ceng)滾筒(tong)散(san)發的(de)(de)熱(re)量(liang)(liang)，又(you)吸(xi)收中層(ceng)(ceng)(ceng)(ceng)滾筒(tong)的(de)(de)熱(re)量(liang)(liang)，同(tong)時(shi)又(you)延(yan)長(chang)了干燥(zao)(zao)(zao)時(shi)間，物(wu)(wu)料(liao)在(zai)(zai)(zai)此達(da)到干燥(zao)(zao)(zao)狀態。物(wu)(wu)料(liao)行(xing)至中層(ceng)(ceng)(ceng)(ceng)另(ling)一端而落(luo)入外層(ceng)(ceng)(ceng)(ceng)，物(wu)(wu)料(liao)在(zai)(zai)(zai)外層(ceng)(ceng)(ceng)(ceng)滾筒(tong)內呈(cheng)矩形多回路方(fang)式(shi)(shi)行(xing)進(jin)，達(da)到干燥(zao)(zao)(zao)效果(guo)的(de)(de)物(wu)(wu)料(liao)在(zai)(zai)(zai)熱(re)風作用下快速(su)行(xing)進(jin)排出滾筒(tong)，沒有達(da)到干燥(zao)(zao)(zao)效果(guo)的(de)(de)濕物(wu)(wu)料(liao)因(yin)自重(zhong)而不能快速(su)行(xing)進(jin)，物(wu)(wu)料(liao)在(zai)(zai)(zai)此矩形抄(chao)板(ban)內進(jin)行(xing)充(chong)(chong)分干燥(zao)(zao)(zao)，由此完成干燥(zao)(zao)(zao)目的(de)(de)。
