產品概況(kuang)
回轉式三筒烘(hong)干(gan)(gan)(gan)機(ji)改進(jin)原單(dan)筒烘(hong)干(gan)(gan)(gan)機(ji)內部結構，增加入機(ji)前濕料的預(yu)烘(hong)干(gan)(gan)(gan)和(he)延(yan)長濕料在機(ji)內烘(hong)干(gan)(gan)(gan)時間，再(zai)加上密封、保(bao)溫以及合理(li)的配套措施，使烘(hong)干(gan)(gan)(gan)機(ji)生產能力與原單(dan)筒式烘(hong)干(gan)(gan)(gan)機(ji)相比(bi)，提高48-80%，單(dan)位容(rong)積蒸發強(qiang)度可達120-180kg/m3，標準煤耗僅為(wei)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(zha)、粘土、煤。
產品結構
三筒(tong)烘(hong)干(gan)機是通過(guo)對單(dan)筒(tong)烘(hong)干(gan)機的(de)單(dan)筒(tong)體(ti)改為套疊(die)在(zai)一起的(de)三筒(tong)，以縮短烘(hong)干(gan)機體(ti)的(de)外形尺寸。該機工(gong)作(zuo)時，物(wu)料和(he)熱氣流依次進(jin)入內至外筒(tong)體(ti)，在(zai)機體(ti)Z形往復折流后(hou)，充分利用熱能烘(hong)干(gan)物(wu)料后(hou)再卸出(chu)。
烘干(gan)機筒(tong)(tong)(tong)(tong)體(ti)部(bu)分由三個同軸水平(ping)放置的(de)內、中、外筒(tong)(tong)(tong)(tong)套疊組成，這就(jiu)使筒(tong)(tong)(tong)(tong)體(ti)的(de)截(jie)面得(de)到(dao)充(chong)分的(de)利用。其筒(tong)(tong)(tong)(tong)體(ti)外形總長度約為與之相當的(de)單(dan)筒(tong)(tong)(tong)(tong)的(de)30-35%。從(cong)而大幅度地減少占地面積和(he)廠房建筑(zhu)面積。
該機(ji)的支(zhi)承裝置(zhi)，是在外筒(tong)上輪帶(dai)與(yu)托輪支(zhi)承，由電機(ji)直接(jie)帶(dai)動托輪。通過托輪與(yu)輪帶(dai)摩擦，使(shi)筒(tong)體轉動。該機(ji)總(zong)體結構(gou)緊湊、合理、簡(jian)單，為(wei)便(bian)于磨損件的檢(jian)修(xiu)更換，在中間設計成軸(zhou)向剖分(fen)式，用螺栓(shuan)固(gu)定連接(jie)。
工作原理
物(wu)料(liao)(liao)(liao)(liao)由供(gong)料(liao)(liao)(liao)(liao)裝置進(jin)入(ru)回轉滾(gun)筒(tong)的(de)(de)內(nei)(nei)層(ceng)(ceng),實(shi)現(xian)順流烘干(gan)(gan),物(wu)料(liao)(liao)(liao)(liao)在(zai)內(nei)(nei)層(ceng)(ceng)的(de)(de)抄(chao)板下(xia)不(bu)(bu)斷抄(chao)起、散落呈(cheng)(cheng)螺(luo)旋行(xing)(xing)(xing)進(jin)式實(shi)現(xian)熱(re)交換，物(wu)料(liao)(liao)(liao)(liao)移(yi)動至內(nei)(nei)層(ceng)(ceng)的(de)(de)另(ling)一(yi)端(duan)進(jin)入(ru)中(zhong)層(ceng)(ceng)，進(jin)行(xing)(xing)(xing)逆流烘干(gan)(gan)，物(wu)料(liao)(liao)(liao)(liao)在(zai)中(zhong)層(ceng)(ceng)不(bu)(bu)斷地被反復(fu)揚進(jin)，呈(cheng)(cheng)進(jin)兩步(bu)退一(yi)步(bu)的(de)(de)行(xing)(xing)(xing)進(jin)方式，物(wu)料(liao)(liao)(liao)(liao)在(zai)中(zhong)層(ceng)(ceng)既充分吸收內(nei)(nei)層(ceng)(ceng)滾(gun)筒(tong)散發(fa)的(de)(de)熱(re)量，又吸收中(zhong)層(ceng)(ceng)滾(gun)筒(tong)的(de)(de)熱(re)量，同時又延長了干(gan)(gan)燥(zao)(zao)時間，物(wu)料(liao)(liao)(liao)(liao)在(zai)此達(da)到干(gan)(gan)燥(zao)(zao)狀態。物(wu)料(liao)(liao)(liao)(liao)行(xing)(xing)(xing)至中(zhong)層(ceng)(ceng)另(ling)一(yi)端(duan)而落入(ru)外層(ceng)(ceng)，物(wu)料(liao)(liao)(liao)(liao)在(zai)外層(ceng)(ceng)滾(gun)筒(tong)內(nei)(nei)呈(cheng)(cheng)矩形(xing)多回路方式行(xing)(xing)(xing)進(jin)，達(da)到干(gan)(gan)燥(zao)(zao)效(xiao)果(guo)的(de)(de)物(wu)料(liao)(liao)(liao)(liao)在(zai)熱(re)風(feng)作用下(xia)快速(su)行(xing)(xing)(xing)進(jin)排出滾(gun)筒(tong)，沒有達(da)到干(gan)(gan)燥(zao)(zao)效(xiao)果(guo)的(de)(de)濕(shi)物(wu)料(liao)(liao)(liao)(liao)因自重而不(bu)(bu)能(neng)快速(su)行(xing)(xing)(xing)進(jin)，物(wu)料(liao)(liao)(liao)(liao)在(zai)此矩形(xing)抄(chao)板內(nei)(nei)進(jin)行(xing)(xing)(xing)充分干(gan)(gan)燥(zao)(zao)，由此完(wan)成干(gan)(gan)燥(zao)(zao)目的(de)(de)。
