產品(pin)概況
回(hui)轉式(shi)三筒烘(hong)干(gan)機(ji)改進原(yuan)單筒烘(hong)干(gan)機(ji)內(nei)部(bu)結構，增加(jia)入(ru)機(ji)前(qian)濕(shi)料(liao)的(de)預烘(hong)干(gan)和延(yan)長濕(shi)料(liao)在(zai)機(ji)內(nei)烘(hong)干(gan)時(shi)間，再加(jia)上密(mi)封、保(bao)溫以及合理的(de)配(pei)套措施，使烘(hong)干(gan)機(ji)生產能力與原(yuan)單筒式(shi)烘(hong)干(gan)機(ji)相比，提高(gao)48-80%，單位容積蒸發強度可達120-180kg/m3，標準煤(mei)耗僅為(wei)6-8kg/t。其(qi)技術先進、運行(xing)參(can)數合理，操作簡單可行(xing)，廣泛應用(yong)于各個行(xing)業的(de)礦渣、粘土(tu)、煤(mei)。
產品結構
三(san)(san)筒(tong)(tong)(tong)(tong)烘(hong)(hong)干(gan)機是通過對單筒(tong)(tong)(tong)(tong)烘(hong)(hong)干(gan)機的(de)單筒(tong)(tong)(tong)(tong)體(ti)(ti)改為套疊在一起的(de)三(san)(san)筒(tong)(tong)(tong)(tong)，以縮短(duan)烘(hong)(hong)干(gan)機體(ti)(ti)的(de)外形尺(chi)寸(cun)。該機工作時，物料(liao)和熱氣(qi)流依次進入內(nei)至(zhi)外筒(tong)(tong)(tong)(tong)體(ti)(ti)，在機體(ti)(ti)Z形往復折流后，充分利用熱能烘(hong)(hong)干(gan)物料(liao)后再卸出。
烘干(gan)機筒(tong)(tong)(tong)體部分由三個同軸水平(ping)放置的(de)內、中、外(wai)筒(tong)(tong)(tong)套疊(die)組成，這就使筒(tong)(tong)(tong)體的(de)截面得到充分的(de)利用。其(qi)筒(tong)(tong)(tong)體外(wai)形總長度約為與(yu)之相當的(de)單筒(tong)(tong)(tong)的(de)30-35%。從而(er)大幅度地減少占地面積和廠房(fang)建筑(zhu)面積。
該(gai)機(ji)的支(zhi)承裝置(zhi)，是在外筒上輪帶(dai)與(yu)托輪支(zhi)承，由電機(ji)直(zhi)接帶(dai)動(dong)托輪。通過托輪與(yu)輪帶(dai)摩擦，使筒體轉動(dong)。該(gai)機(ji)總體結構(gou)緊湊、合理、簡單，為便于磨損件的檢(jian)修更換，在中(zhong)間設計成軸向剖分式，用(yong)螺栓固定(ding)連接。
工作原理
物(wu)(wu)料(liao)(liao)由供(gong)料(liao)(liao)裝(zhuang)置進入(ru)(ru)回轉滾筒(tong)的(de)(de)內(nei)(nei)層,實現順流(liu)(liu)烘干(gan)(gan),物(wu)(wu)料(liao)(liao)在(zai)(zai)內(nei)(nei)層的(de)(de)抄(chao)板(ban)下不斷(duan)抄(chao)起、散落(luo)呈(cheng)螺旋行(xing)進式(shi)實現熱(re)(re)交換，物(wu)(wu)料(liao)(liao)移動至(zhi)內(nei)(nei)層的(de)(de)另(ling)一(yi)端進入(ru)(ru)中(zhong)層，進行(xing)逆流(liu)(liu)烘干(gan)(gan)，物(wu)(wu)料(liao)(liao)在(zai)(zai)中(zhong)層不斷(duan)地(di)被反復(fu)揚進，呈(cheng)進兩步(bu)退一(yi)步(bu)的(de)(de)行(xing)進方式(shi)，物(wu)(wu)料(liao)(liao)在(zai)(zai)中(zhong)層既充(chong)分(fen)吸收內(nei)(nei)層滾筒(tong)散發的(de)(de)熱(re)(re)量，又(you)吸收中(zhong)層滾筒(tong)的(de)(de)熱(re)(re)量，同(tong)時又(you)延長了干(gan)(gan)燥時間，物(wu)(wu)料(liao)(liao)在(zai)(zai)此達到干(gan)(gan)燥狀(zhuang)態。物(wu)(wu)料(liao)(liao)行(xing)至(zhi)中(zhong)層另(ling)一(yi)端而(er)落(luo)入(ru)(ru)外層，物(wu)(wu)料(liao)(liao)在(zai)(zai)外層滾筒(tong)內(nei)(nei)呈(cheng)矩形多回路方式(shi)行(xing)進，達到干(gan)(gan)燥效(xiao)果的(de)(de)物(wu)(wu)料(liao)(liao)在(zai)(zai)熱(re)(re)風作用下快速行(xing)進排出滾筒(tong)，沒有達到干(gan)(gan)燥效(xiao)果的(de)(de)濕物(wu)(wu)料(liao)(liao)因自重(zhong)而(er)不能快速行(xing)進，物(wu)(wu)料(liao)(liao)在(zai)(zai)此矩形抄(chao)板(ban)內(nei)(nei)進行(xing)充(chong)分(fen)干(gan)(gan)燥，由此完成干(gan)(gan)燥目(mu)的(de)(de)。
