產品(pin)概況
回(hui)轉(zhuan)式(shi)三筒(tong)烘(hong)(hong)干(gan)機(ji)改(gai)進(jin)原(yuan)單(dan)(dan)筒(tong)烘(hong)(hong)干(gan)機(ji)內(nei)部結構，增加(jia)入(ru)機(ji)前濕料的預烘(hong)(hong)干(gan)和延長濕料在機(ji)內(nei)烘(hong)(hong)干(gan)時間，再加(jia)上密封、保溫以及合理的配套措施，使烘(hong)(hong)干(gan)機(ji)生產(chan)能力與原(yuan)單(dan)(dan)筒(tong)式(shi)烘(hong)(hong)干(gan)機(ji)相(xiang)比，提高48-80%，單(dan)(dan)位(wei)容(rong)積(ji)蒸發強度可(ke)達120-180kg/m3，標準煤耗(hao)僅為6-8kg/t。其技術先進(jin)、運行參數合理，操作簡單(dan)(dan)可(ke)行，廣泛應用于各個行業(ye)的礦渣(zha)、粘(zhan)土、煤。
產品(pin)結構(gou)
三筒(tong)(tong)烘(hong)干(gan)機(ji)(ji)是通過對單筒(tong)(tong)烘(hong)干(gan)機(ji)(ji)的單筒(tong)(tong)體(ti)改為套疊在一(yi)起的三筒(tong)(tong)，以(yi)縮短烘(hong)干(gan)機(ji)(ji)體(ti)的外形尺寸。該機(ji)(ji)工作時，物料(liao)和熱氣流依次(ci)進入(ru)內至(zhi)外筒(tong)(tong)體(ti)，在機(ji)(ji)體(ti)Z形往復折流后，充(chong)分利(li)用熱能(neng)烘(hong)干(gan)物料(liao)后再卸出。
烘干(gan)機筒體(ti)(ti)部分(fen)由(you)三個同軸水平放置的(de)內、中、外筒套(tao)疊組成，這就(jiu)使筒體(ti)(ti)的(de)截面(mian)得到充分(fen)的(de)利用。其筒體(ti)(ti)外形總長度(du)約為與之相當(dang)的(de)單(dan)筒的(de)30-35%。從而大幅度(du)地(di)減(jian)少(shao)占地(di)面(mian)積和廠(chang)房建筑(zhu)面(mian)積。
該(gai)機(ji)的(de)支承(cheng)裝置，是在(zai)外筒上輪(lun)帶(dai)與托(tuo)輪(lun)支承(cheng)，由(you)電機(ji)直(zhi)接(jie)帶(dai)動托(tuo)輪(lun)。通過托(tuo)輪(lun)與輪(lun)帶(dai)摩擦，使筒體(ti)轉動。該(gai)機(ji)總體(ti)結構緊(jin)湊、合理、簡單，為便于(yu)磨(mo)損件的(de)檢修更換，在(zai)中間設計成軸向剖(pou)分式(shi)，用螺栓固(gu)定(ding)連接(jie)。
工作原理
物(wu)(wu)(wu)料(liao)(liao)(liao)由供料(liao)(liao)(liao)裝置進(jin)(jin)入(ru)回(hui)轉滾筒(tong)(tong)(tong)(tong)的(de)內(nei)層(ceng)(ceng),實(shi)現順流烘(hong)(hong)干(gan)(gan),物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)內(nei)層(ceng)(ceng)的(de)抄板下(xia)不斷(duan)抄起、散落(luo)呈(cheng)(cheng)螺(luo)旋(xuan)行進(jin)(jin)式實(shi)現熱(re)(re)交換(huan)，物(wu)(wu)(wu)料(liao)(liao)(liao)移動至內(nei)層(ceng)(ceng)的(de)另(ling)一(yi)(yi)端進(jin)(jin)入(ru)中(zhong)(zhong)層(ceng)(ceng)，進(jin)(jin)行逆(ni)流烘(hong)(hong)干(gan)(gan)，物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)中(zhong)(zhong)層(ceng)(ceng)不斷(duan)地被反復揚(yang)進(jin)(jin)，呈(cheng)(cheng)進(jin)(jin)兩步(bu)退一(yi)(yi)步(bu)的(de)行進(jin)(jin)方(fang)式，物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)中(zhong)(zhong)層(ceng)(ceng)既充分吸收(shou)內(nei)層(ceng)(ceng)滾筒(tong)(tong)(tong)(tong)散發的(de)熱(re)(re)量(liang)(liang)，又(you)吸收(shou)中(zhong)(zhong)層(ceng)(ceng)滾筒(tong)(tong)(tong)(tong)的(de)熱(re)(re)量(liang)(liang)，同時又(you)延長了(le)干(gan)(gan)燥(zao)時間(jian)，物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)此達(da)到干(gan)(gan)燥(zao)狀態。物(wu)(wu)(wu)料(liao)(liao)(liao)行至中(zhong)(zhong)層(ceng)(ceng)另(ling)一(yi)(yi)端而落(luo)入(ru)外層(ceng)(ceng)，物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)外層(ceng)(ceng)滾筒(tong)(tong)(tong)(tong)內(nei)呈(cheng)(cheng)矩形多回(hui)路方(fang)式行進(jin)(jin)，達(da)到干(gan)(gan)燥(zao)效果的(de)物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)熱(re)(re)風作用下(xia)快速行進(jin)(jin)排出滾筒(tong)(tong)(tong)(tong)，沒有達(da)到干(gan)(gan)燥(zao)效果的(de)濕物(wu)(wu)(wu)料(liao)(liao)(liao)因自重(zhong)而不能(neng)快速行進(jin)(jin)，物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)此矩形抄板內(nei)進(jin)(jin)行充分干(gan)(gan)燥(zao)，由此完成干(gan)(gan)燥(zao)目(mu)的(de)。
