產品(pin)概況(kuang)
回轉式三筒(tong)烘(hong)(hong)(hong)干(gan)(gan)機(ji)(ji)改(gai)進(jin)原(yuan)單(dan)筒(tong)烘(hong)(hong)(hong)干(gan)(gan)機(ji)(ji)內部結構，增加入(ru)機(ji)(ji)前(qian)濕(shi)料的預烘(hong)(hong)(hong)干(gan)(gan)和延長濕(shi)料在機(ji)(ji)內烘(hong)(hong)(hong)干(gan)(gan)時間，再加上密封、保溫以及(ji)合理(li)的配套措施，使烘(hong)(hong)(hong)干(gan)(gan)機(ji)(ji)生產能力與原(yuan)單(dan)筒(tong)式烘(hong)(hong)(hong)干(gan)(gan)機(ji)(ji)相比(bi)，提高48-80%，單(dan)位容積蒸發強(qiang)度可達120-180kg/m3，標(biao)準(zhun)煤耗僅為6-8kg/t。其技術先進(jin)、運行參數合理(li)，操作簡單(dan)可行，廣泛應用于(yu)各個行業的礦渣、粘土、煤。
產(chan)品(pin)結構
三筒(tong)(tong)烘干機(ji)(ji)(ji)是通過對單筒(tong)(tong)烘干機(ji)(ji)(ji)的單筒(tong)(tong)體改(gai)為套疊在一起的三筒(tong)(tong)，以(yi)縮短烘干機(ji)(ji)(ji)體的外形(xing)尺(chi)寸(cun)。該機(ji)(ji)(ji)工作(zuo)時，物(wu)料和熱(re)氣(qi)流(liu)(liu)依次進入內至外筒(tong)(tong)體，在機(ji)(ji)(ji)體Z形(xing)往復折流(liu)(liu)后，充分利(li)用熱(re)能(neng)烘干物(wu)料后再卸出。
烘干(gan)機(ji)筒(tong)體部分由三個(ge)同軸水平放(fang)置的(de)內、中、外筒(tong)套疊(die)組成，這就使筒(tong)體的(de)截(jie)面得到充分的(de)利用(yong)。其筒(tong)體外形總長(chang)度(du)約為與之相當(dang)的(de)單筒(tong)的(de)30-35%。從而(er)大(da)幅度(du)地減少占地面積(ji)和廠房建筑(zhu)面積(ji)。
該(gai)機的支承裝置，是在(zai)外筒(tong)上輪(lun)帶(dai)與托輪(lun)支承，由電機直接帶(dai)動托輪(lun)。通過(guo)托輪(lun)與輪(lun)帶(dai)摩擦，使筒(tong)體(ti)(ti)轉動。該(gai)機總體(ti)(ti)結構(gou)緊湊、合理(li)、簡單，為便于磨損件的檢修更換，在(zai)中間設計成(cheng)軸向剖分(fen)式，用(yong)螺栓固定連接。
工作(zuo)原理
物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)由供料(liao)(liao)(liao)(liao)(liao)裝(zhuang)置進(jin)(jin)入(ru)回轉滾(gun)(gun)筒的(de)(de)內(nei)層(ceng)(ceng)(ceng)(ceng),實(shi)現順流烘干(gan),物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)內(nei)層(ceng)(ceng)(ceng)(ceng)的(de)(de)抄板下不(bu)斷抄起、散落(luo)呈螺旋(xuan)行(xing)(xing)(xing)(xing)進(jin)(jin)式實(shi)現熱(re)交換(huan)，物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)移動(dong)至內(nei)層(ceng)(ceng)(ceng)(ceng)的(de)(de)另(ling)一端進(jin)(jin)入(ru)中(zhong)層(ceng)(ceng)(ceng)(ceng)，進(jin)(jin)行(xing)(xing)(xing)(xing)逆流烘干(gan)，物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)中(zhong)層(ceng)(ceng)(ceng)(ceng)不(bu)斷地被(bei)反復揚(yang)進(jin)(jin)，呈進(jin)(jin)兩步退(tui)一步的(de)(de)行(xing)(xing)(xing)(xing)進(jin)(jin)方式，物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)中(zhong)層(ceng)(ceng)(ceng)(ceng)既充分吸收(shou)內(nei)層(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)筒散發的(de)(de)熱(re)量，又吸收(shou)中(zhong)層(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)筒的(de)(de)熱(re)量，同時(shi)又延長(chang)了干(gan)燥(zao)時(shi)間(jian)，物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)此達到干(gan)燥(zao)狀(zhuang)態。物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)行(xing)(xing)(xing)(xing)至中(zhong)層(ceng)(ceng)(ceng)(ceng)另(ling)一端而落(luo)入(ru)外層(ceng)(ceng)(ceng)(ceng)，物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)外層(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)筒內(nei)呈矩(ju)形(xing)多回路方式行(xing)(xing)(xing)(xing)進(jin)(jin)，達到干(gan)燥(zao)效(xiao)果的(de)(de)物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)熱(re)風作用下快速(su)行(xing)(xing)(xing)(xing)進(jin)(jin)排出滾(gun)(gun)筒，沒有達到干(gan)燥(zao)效(xiao)果的(de)(de)濕物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)因(yin)自重而不(bu)能(neng)快速(su)行(xing)(xing)(xing)(xing)進(jin)(jin)，物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)此矩(ju)形(xing)抄板內(nei)進(jin)(jin)行(xing)(xing)(xing)(xing)充分干(gan)燥(zao)，由此完(wan)成干(gan)燥(zao)目的(de)(de)。
