產品(pin)概況(kuang)
回(hui)轉式三筒(tong)烘(hong)(hong)(hong)干(gan)機(ji)改進原單筒(tong)烘(hong)(hong)(hong)干(gan)機(ji)內部結構，增加(jia)入機(ji)前濕料(liao)的預烘(hong)(hong)(hong)干(gan)和延長濕料(liao)在機(ji)內烘(hong)(hong)(hong)干(gan)時間(jian)，再加(jia)上密(mi)封(feng)、保溫以及(ji)合理(li)的配套措(cuo)施，使烘(hong)(hong)(hong)干(gan)機(ji)生產能力與原單筒(tong)式烘(hong)(hong)(hong)干(gan)機(ji)相比，提(ti)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(qi)技術先進、運行參數合理(li)，操作簡(jian)單可行，廣泛應用于各個行業(ye)的礦渣、粘(zhan)土、煤。
產(chan)品結構
三筒(tong)(tong)(tong)(tong)烘(hong)(hong)干(gan)(gan)機(ji)是(shi)通過(guo)對單(dan)筒(tong)(tong)(tong)(tong)烘(hong)(hong)干(gan)(gan)機(ji)的(de)單(dan)筒(tong)(tong)(tong)(tong)體(ti)(ti)改為套疊在一起的(de)三筒(tong)(tong)(tong)(tong)，以(yi)縮短烘(hong)(hong)干(gan)(gan)機(ji)體(ti)(ti)的(de)外(wai)形尺寸。該機(ji)工作(zuo)時，物料(liao)和熱氣流(liu)依次進入(ru)內至(zhi)外(wai)筒(tong)(tong)(tong)(tong)體(ti)(ti)，在機(ji)體(ti)(ti)Z形往復折(zhe)流(liu)后(hou)，充分利用熱能(neng)烘(hong)(hong)干(gan)(gan)物料(liao)后(hou)再卸出(chu)。
烘干機筒(tong)體(ti)部分(fen)(fen)由三個(ge)同軸水(shui)平放(fang)置的(de)(de)內、中、外筒(tong)套疊組成，這就使筒(tong)體(ti)的(de)(de)截面得(de)到充分(fen)(fen)的(de)(de)利用。其筒(tong)體(ti)外形總(zong)長度(du)約(yue)為(wei)與之相(xiang)當的(de)(de)單筒(tong)的(de)(de)30-35%。從而大幅度(du)地(di)減少占地(di)面積和廠房建(jian)筑面積。
該(gai)機的支承裝置，是在外(wai)筒上(shang)輪(lun)(lun)帶與托(tuo)輪(lun)(lun)支承，由電機直接帶動(dong)托(tuo)輪(lun)(lun)。通過托(tuo)輪(lun)(lun)與輪(lun)(lun)帶摩擦，使筒體(ti)轉(zhuan)動(dong)。該(gai)機總(zong)體(ti)結構緊湊、合理、簡單，為便于磨(mo)損件(jian)的檢修(xiu)更換，在中間設計成軸(zhou)向剖分式，用螺栓固定連(lian)接。
工作原理
物(wu)(wu)料(liao)(liao)由供(gong)料(liao)(liao)裝置進(jin)(jin)入(ru)回轉(zhuan)滾筒(tong)的(de)內(nei)(nei)(nei)層(ceng)(ceng),實(shi)現順流烘(hong)干(gan)(gan),物(wu)(wu)料(liao)(liao)在(zai)內(nei)(nei)(nei)層(ceng)(ceng)的(de)抄板(ban)下不斷抄起、散落呈(cheng)螺(luo)旋行(xing)進(jin)(jin)式(shi)實(shi)現熱(re)交(jiao)換，物(wu)(wu)料(liao)(liao)移動至內(nei)(nei)(nei)層(ceng)(ceng)的(de)另一(yi)端進(jin)(jin)入(ru)中(zhong)層(ceng)(ceng)，進(jin)(jin)行(xing)逆流烘(hong)干(gan)(gan)，物(wu)(wu)料(liao)(liao)在(zai)中(zhong)層(ceng)(ceng)不斷地被(bei)反復揚進(jin)(jin)，呈(cheng)進(jin)(jin)兩步退一(yi)步的(de)行(xing)進(jin)(jin)方式(shi)，物(wu)(wu)料(liao)(liao)在(zai)中(zhong)層(ceng)(ceng)既充(chong)分(fen)(fen)吸(xi)收(shou)內(nei)(nei)(nei)層(ceng)(ceng)滾筒(tong)散發的(de)熱(re)量(liang)，又(you)吸(xi)收(shou)中(zhong)層(ceng)(ceng)滾筒(tong)的(de)熱(re)量(liang)，同時又(you)延(yan)長了干(gan)(gan)燥(zao)(zao)時間(jian)，物(wu)(wu)料(liao)(liao)在(zai)此達到干(gan)(gan)燥(zao)(zao)狀(zhuang)態。物(wu)(wu)料(liao)(liao)行(xing)至中(zhong)層(ceng)(ceng)另一(yi)端而(er)落入(ru)外層(ceng)(ceng)，物(wu)(wu)料(liao)(liao)在(zai)外層(ceng)(ceng)滾筒(tong)內(nei)(nei)(nei)呈(cheng)矩形(xing)多回路方式(shi)行(xing)進(jin)(jin)，達到干(gan)(gan)燥(zao)(zao)效果的(de)物(wu)(wu)料(liao)(liao)在(zai)熱(re)風作用下快速行(xing)進(jin)(jin)排出滾筒(tong)，沒有(you)達到干(gan)(gan)燥(zao)(zao)效果的(de)濕物(wu)(wu)料(liao)(liao)因自重(zhong)而(er)不能(neng)快速行(xing)進(jin)(jin)，物(wu)(wu)料(liao)(liao)在(zai)此矩形(xing)抄板(ban)內(nei)(nei)(nei)進(jin)(jin)行(xing)充(chong)分(fen)(fen)干(gan)(gan)燥(zao)(zao)，由此完成干(gan)(gan)燥(zao)(zao)目的(de)。
