產品概況
回轉式三筒(tong)(tong)烘(hong)(hong)(hong)(hong)干機(ji)(ji)(ji)改(gai)進(jin)原單筒(tong)(tong)烘(hong)(hong)(hong)(hong)干機(ji)(ji)(ji)內部結(jie)構，增加入機(ji)(ji)(ji)前濕料(liao)的預烘(hong)(hong)(hong)(hong)干和延長濕料(liao)在(zai)機(ji)(ji)(ji)內烘(hong)(hong)(hong)(hong)干時間，再(zai)加上密封、保(bao)溫以及合理(li)的配套(tao)措施，使烘(hong)(hong)(hong)(hong)干機(ji)(ji)(ji)生產能力與(yu)原單筒(tong)(tong)式烘(hong)(hong)(hong)(hong)干機(ji)(ji)(ji)相(xiang)比，提高48-80%，單位容(rong)積蒸發強度可(ke)達120-180kg/m3，標(biao)準煤耗僅為6-8kg/t。其技術先進(jin)、運行(xing)(xing)參數合理(li)，操作簡單可(ke)行(xing)(xing)，廣泛應用于各(ge)個行(xing)(xing)業的礦(kuang)渣、粘(zhan)土、煤。
產品結構
三筒(tong)(tong)烘干機(ji)(ji)是通過對(dui)單筒(tong)(tong)烘干機(ji)(ji)的單筒(tong)(tong)體改(gai)為套疊(die)在一起的三筒(tong)(tong)，以縮短烘干機(ji)(ji)體的外(wai)形尺寸。該機(ji)(ji)工作(zuo)時，物料(liao)和熱氣(qi)流依(yi)次(ci)進入內至(zhi)外(wai)筒(tong)(tong)體，在機(ji)(ji)體Z形往復折流后(hou)，充分(fen)利用熱能烘干物料(liao)后(hou)再卸出。
烘干機筒體部(bu)分(fen)由三個同軸水平放(fang)置的內、中(zhong)、外筒套(tao)疊組成，這就使筒體的截面(mian)(mian)得到充分(fen)的利用。其(qi)筒體外形總長度約為與之相當的單筒的30-35%。從而(er)大幅度地(di)減少占地(di)面(mian)(mian)積和廠房建筑面(mian)(mian)積。
該(gai)(gai)機的支承裝置，是在(zai)外(wai)筒上輪(lun)帶與托輪(lun)支承，由(you)電機直接帶動托輪(lun)。通過托輪(lun)與輪(lun)帶摩擦，使(shi)筒體(ti)轉動。該(gai)(gai)機總體(ti)結(jie)構緊湊、合理、簡(jian)單(dan)，為便于磨損件的檢修更換(huan)，在(zai)中間設計(ji)成軸向剖分式(shi)，用螺(luo)栓固定連接。
工作原理
物(wu)(wu)(wu)(wu)料(liao)(liao)由供料(liao)(liao)裝置進(jin)(jin)(jin)入回轉滾筒(tong)的內(nei)(nei)(nei)層(ceng)(ceng)(ceng),實現(xian)順流烘干(gan)(gan)(gan),物(wu)(wu)(wu)(wu)料(liao)(liao)在內(nei)(nei)(nei)層(ceng)(ceng)(ceng)的抄板下不斷(duan)抄起、散落呈螺(luo)旋行(xing)進(jin)(jin)(jin)式實現(xian)熱(re)交換，物(wu)(wu)(wu)(wu)料(liao)(liao)移動至內(nei)(nei)(nei)層(ceng)(ceng)(ceng)的另一(yi)端(duan)進(jin)(jin)(jin)入中(zhong)(zhong)層(ceng)(ceng)(ceng)，進(jin)(jin)(jin)行(xing)逆(ni)流烘干(gan)(gan)(gan)，物(wu)(wu)(wu)(wu)料(liao)(liao)在中(zhong)(zhong)層(ceng)(ceng)(ceng)不斷(duan)地被反(fan)復揚進(jin)(jin)(jin)，呈進(jin)(jin)(jin)兩(liang)步(bu)退一(yi)步(bu)的行(xing)進(jin)(jin)(jin)方(fang)式，物(wu)(wu)(wu)(wu)料(liao)(liao)在中(zhong)(zhong)層(ceng)(ceng)(ceng)既充分吸(xi)收內(nei)(nei)(nei)層(ceng)(ceng)(ceng)滾筒(tong)散發的熱(re)量，又吸(xi)收中(zhong)(zhong)層(ceng)(ceng)(ceng)滾筒(tong)的熱(re)量，同時又延長(chang)了干(gan)(gan)(gan)燥(zao)時間(jian)，物(wu)(wu)(wu)(wu)料(liao)(liao)在此達到干(gan)(gan)(gan)燥(zao)狀(zhuang)態。物(wu)(wu)(wu)(wu)料(liao)(liao)行(xing)至中(zhong)(zhong)層(ceng)(ceng)(ceng)另一(yi)端(duan)而(er)落入外層(ceng)(ceng)(ceng)，物(wu)(wu)(wu)(wu)料(liao)(liao)在外層(ceng)(ceng)(ceng)滾筒(tong)內(nei)(nei)(nei)呈矩(ju)形多回路方(fang)式行(xing)進(jin)(jin)(jin)，達到干(gan)(gan)(gan)燥(zao)效果的物(wu)(wu)(wu)(wu)料(liao)(liao)在熱(re)風作用下快速(su)(su)行(xing)進(jin)(jin)(jin)排出滾筒(tong)，沒(mei)有達到干(gan)(gan)(gan)燥(zao)效果的濕物(wu)(wu)(wu)(wu)料(liao)(liao)因(yin)自(zi)重而(er)不能快速(su)(su)行(xing)進(jin)(jin)(jin)，物(wu)(wu)(wu)(wu)料(liao)(liao)在此矩(ju)形抄板內(nei)(nei)(nei)進(jin)(jin)(jin)行(xing)充分干(gan)(gan)(gan)燥(zao)，由此完成干(gan)(gan)(gan)燥(zao)目的。
