產品概況(kuang)
回轉(zhuan)式三筒烘(hong)(hong)(hong)(hong)干(gan)機(ji)(ji)(ji)(ji)(ji)改進(jin)原(yuan)單筒烘(hong)(hong)(hong)(hong)干(gan)機(ji)(ji)(ji)(ji)(ji)內(nei)(nei)部(bu)結構，增(zeng)加入機(ji)(ji)(ji)(ji)(ji)前濕料的預烘(hong)(hong)(hong)(hong)干(gan)和延(yan)長濕料在(zai)機(ji)(ji)(ji)(ji)(ji)內(nei)(nei)烘(hong)(hong)(hong)(hong)干(gan)時間(jian)，再加上密封、保溫(wen)以(yi)及合理的配(pei)套措施，使烘(hong)(hong)(hong)(hong)干(gan)機(ji)(ji)(ji)(ji)(ji)生(sheng)產能(neng)力(li)與原(yuan)單筒式烘(hong)(hong)(hong)(hong)干(gan)機(ji)(ji)(ji)(ji)(ji)相比(bi)，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(jin)、運行(xing)參數合理，操作簡單可行(xing)，廣(guang)泛(fan)應用于(yu)各個行(xing)業(ye)的礦渣(zha)、粘土、煤。
產品(pin)結構
三(san)筒(tong)(tong)(tong)烘(hong)干機(ji)(ji)是通過對單筒(tong)(tong)(tong)烘(hong)干機(ji)(ji)的單筒(tong)(tong)(tong)體(ti)改為套疊在一起的三(san)筒(tong)(tong)(tong)，以縮短(duan)烘(hong)干機(ji)(ji)體(ti)的外形尺寸。該機(ji)(ji)工作時，物料(liao)和熱(re)氣流(liu)依次進入內至外筒(tong)(tong)(tong)體(ti)，在機(ji)(ji)體(ti)Z形往(wang)復折流(liu)后，充分利用熱(re)能(neng)烘(hong)干物料(liao)后再卸出。
烘干機筒(tong)體(ti)(ti)部分(fen)由三個同軸水平(ping)放置的(de)內(nei)、中(zhong)、外筒(tong)套(tao)疊組成，這就使筒(tong)體(ti)(ti)的(de)截面得到充分(fen)的(de)利用。其筒(tong)體(ti)(ti)外形總長度(du)約為與(yu)之相當的(de)單(dan)筒(tong)的(de)30-35%。從而大幅(fu)度(du)地(di)減少(shao)占(zhan)地(di)面積和廠房(fang)建(jian)筑面積。
該機(ji)(ji)的支承裝置，是(shi)在(zai)外筒上輪(lun)(lun)(lun)帶與(yu)托輪(lun)(lun)(lun)支承，由(you)電機(ji)(ji)直接帶動(dong)托輪(lun)(lun)(lun)。通過托輪(lun)(lun)(lun)與(yu)輪(lun)(lun)(lun)帶摩擦(ca)，使筒體轉動(dong)。該機(ji)(ji)總體結構緊(jin)湊、合理(li)、簡單，為(wei)便于磨損(sun)件的檢(jian)修更換(huan)，在(zai)中間設計成軸向剖分式，用螺(luo)栓固定連(lian)接。
工作原理(li)
物(wu)料(liao)(liao)(liao)(liao)由(you)供料(liao)(liao)(liao)(liao)裝置(zhi)進(jin)(jin)入回轉滾(gun)筒(tong)(tong)(tong)的(de)內(nei)層(ceng),實現(xian)順(shun)流(liu)烘干(gan)(gan)(gan),物(wu)料(liao)(liao)(liao)(liao)在(zai)內(nei)層(ceng)的(de)抄(chao)板(ban)(ban)下(xia)不斷抄(chao)起(qi)、散落(luo)(luo)呈(cheng)(cheng)螺(luo)旋行(xing)進(jin)(jin)式(shi)實現(xian)熱(re)交換，物(wu)料(liao)(liao)(liao)(liao)移動(dong)至(zhi)內(nei)層(ceng)的(de)另一端進(jin)(jin)入中層(ceng)，進(jin)(jin)行(xing)逆流(liu)烘干(gan)(gan)(gan)，物(wu)料(liao)(liao)(liao)(liao)在(zai)中層(ceng)不斷地(di)被反復揚(yang)進(jin)(jin)，呈(cheng)(cheng)進(jin)(jin)兩(liang)步(bu)退一步(bu)的(de)行(xing)進(jin)(jin)方式(shi)，物(wu)料(liao)(liao)(liao)(liao)在(zai)中層(ceng)既充分吸收內(nei)層(ceng)滾(gun)筒(tong)(tong)(tong)散發的(de)熱(re)量，又吸收中層(ceng)滾(gun)筒(tong)(tong)(tong)的(de)熱(re)量，同時又延長了干(gan)(gan)(gan)燥時間，物(wu)料(liao)(liao)(liao)(liao)在(zai)此達到(dao)干(gan)(gan)(gan)燥狀(zhuang)態。物(wu)料(liao)(liao)(liao)(liao)行(xing)至(zhi)中層(ceng)另一端而落(luo)(luo)入外(wai)層(ceng)，物(wu)料(liao)(liao)(liao)(liao)在(zai)外(wai)層(ceng)滾(gun)筒(tong)(tong)(tong)內(nei)呈(cheng)(cheng)矩(ju)形多回路方式(shi)行(xing)進(jin)(jin)，達到(dao)干(gan)(gan)(gan)燥效(xiao)果的(de)物(wu)料(liao)(liao)(liao)(liao)在(zai)熱(re)風(feng)作用(yong)下(xia)快(kuai)速(su)行(xing)進(jin)(jin)排(pai)出(chu)滾(gun)筒(tong)(tong)(tong)，沒有達到(dao)干(gan)(gan)(gan)燥效(xiao)果的(de)濕物(wu)料(liao)(liao)(liao)(liao)因自重而不能快(kuai)速(su)行(xing)進(jin)(jin)，物(wu)料(liao)(liao)(liao)(liao)在(zai)此矩(ju)形抄(chao)板(ban)(ban)內(nei)進(jin)(jin)行(xing)充分干(gan)(gan)(gan)燥，由(you)此完成干(gan)(gan)(gan)燥目的(de)。
