產品概況
回轉式三筒烘干機改進原單筒烘干機內部結構，增加入機前濕料的預烘干和延長濕料在機內烘干時間，再加上密封、保溫以及合理的配套措施，使烘干機生產能力與原單筒式烘干機相比，提高48-80%，單位容積蒸發強度可達120-180kg/m3，標準煤耗僅為6-8kg/t。其技術先進、運行參數合理，操作簡單可行，廣泛應用于各個行業的礦渣、粘土、煤。
產品結構
三(san)筒(tong)式烘干(gan)(gan)機(ji)(ji)是通過對單(dan)筒(tong)烘干(gan)(gan)機(ji)(ji)的(de)單(dan)筒(tong)體改(gai)為套疊在(zai)一(yi)起的(de)三(san)筒(tong)，以縮短(duan)烘干(gan)(gan)機(ji)(ji)體的(de)外形尺(chi)寸。該機(ji)(ji)工作時，物料和熱氣(qi)流依次進入(ru)內至外筒(tong)體，在(zai)機(ji)(ji)體Z形往復折流后(hou)(hou)，充分利用熱能烘干(gan)(gan)物料后(hou)(hou)再卸出。
烘干(gan)機(ji)筒(tong)體部分由三個同(tong)軸水平(ping)放置的(de)內、中(zhong)、外筒(tong)套疊組成，這就使筒(tong)體的(de)截面(mian)(mian)得到充分的(de)利用(yong)。其筒(tong)體外形總(zong)長度(du)約為(wei)與之相當的(de)單(dan)筒(tong)的(de)30-35%。從而(er)大幅度(du)地減少占地面(mian)(mian)積和(he)廠(chang)房建筑面(mian)(mian)積。
該(gai)機的支(zhi)承裝置，是(shi)在外筒(tong)上(shang)輪(lun)(lun)帶與(yu)托輪(lun)(lun)支(zhi)承，由(you)電機直接(jie)帶動托輪(lun)(lun)。通過托輪(lun)(lun)與(yu)輪(lun)(lun)帶摩擦，使筒(tong)體轉動。該(gai)機總體結構(gou)緊湊(cou)、合理、簡(jian)單，為便于(yu)磨損件的檢修更換(huan)，在中間設計成軸向剖分(fen)式(shi)，用螺栓固定連接(jie)。
工作原理
物(wu)(wu)料(liao)由(you)供料(liao)裝置(zhi)進(jin)入(ru)(ru)回轉(zhuan)滾(gun)筒(tong)的(de)內(nei)(nei)層(ceng)(ceng)(ceng),實現順流烘干(gan)(gan)(gan),物(wu)(wu)料(liao)在內(nei)(nei)層(ceng)(ceng)(ceng)的(de)抄板下不(bu)斷(duan)抄起、散(san)落(luo)呈(cheng)螺旋行(xing)(xing)(xing)(xing)進(jin)式(shi)實現熱交換(huan)，物(wu)(wu)料(liao)移動(dong)至(zhi)內(nei)(nei)層(ceng)(ceng)(ceng)的(de)另(ling)一(yi)端進(jin)入(ru)(ru)中(zhong)(zhong)層(ceng)(ceng)(ceng)，進(jin)行(xing)(xing)(xing)(xing)逆流烘干(gan)(gan)(gan)，物(wu)(wu)料(liao)在中(zhong)(zhong)層(ceng)(ceng)(ceng)不(bu)斷(duan)地(di)被(bei)反復(fu)揚進(jin)，呈(cheng)進(jin)兩步(bu)退一(yi)步(bu)的(de)行(xing)(xing)(xing)(xing)進(jin)方式(shi)，物(wu)(wu)料(liao)在中(zhong)(zhong)層(ceng)(ceng)(ceng)既充(chong)分吸(xi)收(shou)內(nei)(nei)層(ceng)(ceng)(ceng)滾(gun)筒(tong)散(san)發的(de)熱量，又吸(xi)收(shou)中(zhong)(zhong)層(ceng)(ceng)(ceng)滾(gun)筒(tong)的(de)熱量，同時又延長(chang)了干(gan)(gan)(gan)燥(zao)時間(jian)，物(wu)(wu)料(liao)在此(ci)達到(dao)干(gan)(gan)(gan)燥(zao)狀態。物(wu)(wu)料(liao)行(xing)(xing)(xing)(xing)至(zhi)中(zhong)(zhong)層(ceng)(ceng)(ceng)另(ling)一(yi)端而(er)落(luo)入(ru)(ru)外層(ceng)(ceng)(ceng)，物(wu)(wu)料(liao)在外層(ceng)(ceng)(ceng)滾(gun)筒(tong)內(nei)(nei)呈(cheng)矩形(xing)多回路(lu)方式(shi)行(xing)(xing)(xing)(xing)進(jin)，達到(dao)干(gan)(gan)(gan)燥(zao)效(xiao)果的(de)物(wu)(wu)料(liao)在熱風作用下快速行(xing)(xing)(xing)(xing)進(jin)排出(chu)滾(gun)筒(tong)，沒有(you)達到(dao)干(gan)(gan)(gan)燥(zao)效(xiao)果的(de)濕物(wu)(wu)料(liao)因自重而(er)不(bu)能快速行(xing)(xing)(xing)(xing)進(jin)，物(wu)(wu)料(liao)在此(ci)矩形(xing)抄板內(nei)(nei)進(jin)行(xing)(xing)(xing)(xing)充(chong)分干(gan)(gan)(gan)燥(zao)，由(you)此(ci)完成干(gan)(gan)(gan)燥(zao)目的(de)。
