產品(pin)概(gai)況
回轉式三筒烘(hong)(hong)(hong)干(gan)(gan)機(ji)改進(jin)原(yuan)單筒烘(hong)(hong)(hong)干(gan)(gan)機(ji)內(nei)部結構，增加入機(ji)前濕料(liao)的預烘(hong)(hong)(hong)干(gan)(gan)和(he)延長濕料(liao)在機(ji)內(nei)烘(hong)(hong)(hong)干(gan)(gan)時間，再加上密封、保溫以(yi)及(ji)合(he)理的配套措施，使烘(hong)(hong)(hong)干(gan)(gan)機(ji)生(sheng)產能力與原(yuan)單筒式烘(hong)(hong)(hong)干(gan)(gan)機(ji)相比，提(ti)高(gao)48-80%，單位容(rong)積(ji)蒸(zheng)發強度可達120-180kg/m3，標準煤耗僅為(wei)6-8kg/t。其技術(shu)先(xian)進(jin)、運行(xing)參數合(he)理，操作簡單可行(xing)，廣泛應(ying)用于(yu)各個行(xing)業的礦渣、粘土、煤。
產品(pin)結構
三筒(tong)烘(hong)干機(ji)是(shi)通過對(dui)單筒(tong)烘(hong)干機(ji)的(de)單筒(tong)體(ti)改為套疊在一起的(de)三筒(tong)，以縮短烘(hong)干機(ji)體(ti)的(de)外形尺(chi)寸。該機(ji)工作時，物料和(he)熱(re)氣流(liu)依次進入內(nei)至外筒(tong)體(ti)，在機(ji)體(ti)Z形往復折流(liu)后(hou)，充分利用熱(re)能烘(hong)干物料后(hou)再卸出。
烘干機筒(tong)(tong)體(ti)部分(fen)由三個同軸水(shui)平放置(zhi)的內、中、外筒(tong)(tong)套疊組成，這就(jiu)使筒(tong)(tong)體(ti)的截面得到(dao)充分(fen)的利用。其筒(tong)(tong)體(ti)外形總長度(du)約(yue)為與之相當的單筒(tong)(tong)的30-35%。從而大幅度(du)地減少(shao)占地面積和(he)廠房建筑面積。
該機的(de)支(zhi)承(cheng)裝置，是在(zai)外筒上輪帶(dai)與托輪支(zhi)承(cheng)，由電機直接(jie)(jie)帶(dai)動托輪。通過托輪與輪帶(dai)摩擦，使(shi)筒體(ti)轉動。該機總體(ti)結(jie)構緊(jin)湊(cou)、合理、簡單，為便于磨損件的(de)檢修(xiu)更換，在(zai)中間設計成軸向剖分式(shi)，用螺栓固定連接(jie)(jie)。
工作(zuo)原理
物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)由供料(liao)(liao)(liao)(liao)裝置進(jin)(jin)入(ru)回(hui)轉滾筒(tong)(tong)的(de)(de)(de)(de)內(nei)層(ceng)(ceng)(ceng)(ceng),實(shi)現(xian)(xian)順流(liu)烘干(gan)(gan),物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在內(nei)層(ceng)(ceng)(ceng)(ceng)的(de)(de)(de)(de)抄(chao)板下不斷(duan)抄(chao)起、散落(luo)呈(cheng)螺旋行(xing)(xing)(xing)進(jin)(jin)式(shi)實(shi)現(xian)(xian)熱交(jiao)換，物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)移(yi)動至內(nei)層(ceng)(ceng)(ceng)(ceng)的(de)(de)(de)(de)另一端(duan)進(jin)(jin)入(ru)中層(ceng)(ceng)(ceng)(ceng)，進(jin)(jin)行(xing)(xing)(xing)逆流(liu)烘干(gan)(gan)，物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在中層(ceng)(ceng)(ceng)(ceng)不斷(duan)地被反復揚進(jin)(jin)，呈(cheng)進(jin)(jin)兩步退一步的(de)(de)(de)(de)行(xing)(xing)(xing)進(jin)(jin)方式(shi)，物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在中層(ceng)(ceng)(ceng)(ceng)既充分(fen)吸收內(nei)層(ceng)(ceng)(ceng)(ceng)滾筒(tong)(tong)散發的(de)(de)(de)(de)熱量(liang)，又吸收中層(ceng)(ceng)(ceng)(ceng)滾筒(tong)(tong)的(de)(de)(de)(de)熱量(liang)，同時(shi)又延(yan)長了干(gan)(gan)燥(zao)時(shi)間(jian)，物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在此達到(dao)(dao)干(gan)(gan)燥(zao)狀態(tai)。物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)行(xing)(xing)(xing)至中層(ceng)(ceng)(ceng)(ceng)另一端(duan)而落(luo)入(ru)外層(ceng)(ceng)(ceng)(ceng)，物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在外層(ceng)(ceng)(ceng)(ceng)滾筒(tong)(tong)內(nei)呈(cheng)矩(ju)形(xing)多回(hui)路方式(shi)行(xing)(xing)(xing)進(jin)(jin)，達到(dao)(dao)干(gan)(gan)燥(zao)效果(guo)的(de)(de)(de)(de)物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在熱風(feng)作用下快速(su)行(xing)(xing)(xing)進(jin)(jin)排出(chu)滾筒(tong)(tong)，沒有達到(dao)(dao)干(gan)(gan)燥(zao)效果(guo)的(de)(de)(de)(de)濕物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)因(yin)自重而不能快速(su)行(xing)(xing)(xing)進(jin)(jin)，物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在此矩(ju)形(xing)抄(chao)板內(nei)進(jin)(jin)行(xing)(xing)(xing)充分(fen)干(gan)(gan)燥(zao)，由此完成干(gan)(gan)燥(zao)目的(de)(de)(de)(de)。
