產品概(gai)況
回轉式三(san)筒(tong)烘(hong)(hong)干(gan)機(ji)(ji)改(gai)進(jin)原單(dan)筒(tong)烘(hong)(hong)干(gan)機(ji)(ji)內部結構，增加入機(ji)(ji)前濕料(liao)的(de)預烘(hong)(hong)干(gan)和(he)延(yan)長(chang)濕料(liao)在機(ji)(ji)內烘(hong)(hong)干(gan)時間，再加上密封、保溫以及(ji)合理(li)的(de)配套(tao)措施，使烘(hong)(hong)干(gan)機(ji)(ji)生(sheng)產能(neng)力與原單(dan)筒(tong)式烘(hong)(hong)干(gan)機(ji)(ji)相比，提高48-80%，單(dan)位容積蒸發(fa)強度可(ke)達120-180kg/m3，標準煤耗僅為6-8kg/t。其技術先進(jin)、運行(xing)參(can)數合理(li)，操作簡單(dan)可(ke)行(xing)，廣泛應(ying)用于各個行(xing)業的(de)礦渣、粘土(tu)、煤。
產品結(jie)構
三筒(tong)烘(hong)(hong)干機(ji)(ji)是通(tong)過對單筒(tong)烘(hong)(hong)干機(ji)(ji)的單筒(tong)體(ti)改為套疊在一起的三筒(tong)，以(yi)縮短烘(hong)(hong)干機(ji)(ji)體(ti)的外形尺(chi)寸。該機(ji)(ji)工作時，物料(liao)和熱氣流(liu)依次進入內至外筒(tong)體(ti)，在機(ji)(ji)體(ti)Z形往復(fu)折流(liu)后(hou)，充分利用熱能烘(hong)(hong)干物料(liao)后(hou)再卸出。
烘干(gan)機筒體部分(fen)由(you)三個同(tong)軸水平放置的(de)內、中、外筒套疊(die)組(zu)成(cheng)，這就使(shi)筒體的(de)截面得(de)到充分(fen)的(de)利(li)用。其筒體外形(xing)總長度(du)(du)約為與之相當的(de)單筒的(de)30-35%。從而大(da)幅度(du)(du)地(di)(di)減(jian)少占地(di)(di)面積和(he)廠房建(jian)筑面積。
該機的(de)(de)支(zhi)承裝置，是在外(wai)筒(tong)上(shang)輪(lun)帶(dai)與托(tuo)輪(lun)支(zhi)承，由電機直接帶(dai)動托(tuo)輪(lun)。通過托(tuo)輪(lun)與輪(lun)帶(dai)摩擦，使筒(tong)體轉動。該機總體結構緊湊、合理、簡單，為便于磨損件的(de)(de)檢修更換，在中間設計(ji)成軸向剖分(fen)式，用螺(luo)栓固定連接。
工作原理
物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)由供(gong)料(liao)(liao)(liao)(liao)裝(zhuang)置進(jin)(jin)(jin)入(ru)回轉滾筒(tong)的(de)內(nei)層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng),實(shi)現(xian)順流烘(hong)干,物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)內(nei)層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)的(de)抄(chao)板(ban)下(xia)不斷抄(chao)起、散落(luo)(luo)呈螺旋行進(jin)(jin)(jin)式(shi)(shi)實(shi)現(xian)熱交(jiao)換，物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)移動(dong)至內(nei)層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)的(de)另一端進(jin)(jin)(jin)入(ru)中(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)，進(jin)(jin)(jin)行逆流烘(hong)干，物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)中(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)不斷地被反復揚(yang)進(jin)(jin)(jin)，呈進(jin)(jin)(jin)兩步退一步的(de)行進(jin)(jin)(jin)方式(shi)(shi)，物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)中(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)既充分吸收內(nei)層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)滾筒(tong)散發的(de)熱量(liang)，又吸收中(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)滾筒(tong)的(de)熱量(liang)，同時(shi)又延長了干燥(zao)(zao)時(shi)間(jian)，物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)此達到(dao)干燥(zao)(zao)狀(zhuang)態(tai)。物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)行至中(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)另一端而落(luo)(luo)入(ru)外層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)，物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)外層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)滾筒(tong)內(nei)呈矩形多回路方式(shi)(shi)行進(jin)(jin)(jin)，達到(dao)干燥(zao)(zao)效果的(de)物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)熱風作用下(xia)快速(su)行進(jin)(jin)(jin)排(pai)出滾筒(tong)，沒有(you)達到(dao)干燥(zao)(zao)效果的(de)濕物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)因自重而不能快速(su)行進(jin)(jin)(jin)，物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)此矩形抄(chao)板(ban)內(nei)進(jin)(jin)(jin)行充分干燥(zao)(zao)，由此完(wan)成干燥(zao)(zao)目的(de)。
