產品概(gai)況
回(hui)轉式三筒(tong)烘(hong)(hong)干(gan)機(ji)改進原(yuan)單筒(tong)烘(hong)(hong)干(gan)機(ji)內部結構，增加入(ru)機(ji)前濕料的(de)預(yu)烘(hong)(hong)干(gan)和(he)延長濕料在機(ji)內烘(hong)(hong)干(gan)時間，再加上(shang)密封、保(bao)溫以及合(he)理的(de)配套措施，使(shi)烘(hong)(hong)干(gan)機(ji)生(sheng)產(chan)能力(li)與原(yuan)單筒(tong)式烘(hong)(hong)干(gan)機(ji)相比，提高48-80%，單位(wei)容(rong)積蒸(zheng)發強度可達120-180kg/m3，標準煤(mei)耗僅為6-8kg/t。其(qi)技術(shu)先進、運行(xing)參數合(he)理，操作簡單可行(xing)，廣泛(fan)應用(yong)于各個行(xing)業的(de)礦渣、粘土(tu)、煤(mei)。
產品(pin)結構
三(san)筒(tong)(tong)烘干機(ji)是通過對單(dan)筒(tong)(tong)烘干機(ji)的單(dan)筒(tong)(tong)體(ti)改為套(tao)疊在一起的三(san)筒(tong)(tong)，以縮短烘干機(ji)體(ti)的外(wai)形尺寸。該機(ji)工作時(shi)，物(wu)料(liao)和熱氣流依(yi)次進(jin)入內至外(wai)筒(tong)(tong)體(ti)，在機(ji)體(ti)Z形往(wang)復折流后，充分(fen)利用(yong)熱能烘干物(wu)料(liao)后再卸出。
烘(hong)干(gan)機筒(tong)(tong)體(ti)部分由(you)三(san)個同軸(zhou)水(shui)平放(fang)置的內、中(zhong)、外(wai)筒(tong)(tong)套疊組成，這(zhe)就使筒(tong)(tong)體(ti)的截(jie)面得到充分的利用。其(qi)筒(tong)(tong)體(ti)外(wai)形總長度(du)約為(wei)與之相當的單筒(tong)(tong)的30-35%。從而(er)大幅度(du)地減少占地面積(ji)和(he)廠(chang)房建筑面積(ji)。
該機的支承(cheng)裝置，是在(zai)外筒(tong)(tong)上輪帶與(yu)托輪支承(cheng)，由電機直接帶動托輪。通過托輪與(yu)輪帶摩(mo)擦，使筒(tong)(tong)體(ti)轉動。該機總體(ti)結(jie)構緊湊、合理、簡單，為便于(yu)磨損件的檢修更換，在(zai)中間設計成軸(zhou)向(xiang)剖分(fen)式，用螺栓固定連接。
工作原理
物(wu)(wu)(wu)料(liao)(liao)由供(gong)料(liao)(liao)裝置進(jin)(jin)(jin)(jin)(jin)入回轉滾(gun)筒(tong)的(de)內(nei)(nei)層(ceng),實現順(shun)流(liu)烘(hong)(hong)干(gan)(gan)(gan),物(wu)(wu)(wu)料(liao)(liao)在(zai)內(nei)(nei)層(ceng)的(de)抄(chao)板下不(bu)斷(duan)(duan)抄(chao)起、散落呈(cheng)螺旋(xuan)行(xing)進(jin)(jin)(jin)(jin)(jin)式實現熱交(jiao)換，物(wu)(wu)(wu)料(liao)(liao)移(yi)動至(zhi)內(nei)(nei)層(ceng)的(de)另(ling)一端進(jin)(jin)(jin)(jin)(jin)入中(zhong)層(ceng)，進(jin)(jin)(jin)(jin)(jin)行(xing)逆流(liu)烘(hong)(hong)干(gan)(gan)(gan)，物(wu)(wu)(wu)料(liao)(liao)在(zai)中(zhong)層(ceng)不(bu)斷(duan)(duan)地被(bei)反(fan)復揚進(jin)(jin)(jin)(jin)(jin)，呈(cheng)進(jin)(jin)(jin)(jin)(jin)兩步退一步的(de)行(xing)進(jin)(jin)(jin)(jin)(jin)方式，物(wu)(wu)(wu)料(liao)(liao)在(zai)中(zhong)層(ceng)既(ji)充分吸(xi)(xi)收內(nei)(nei)層(ceng)滾(gun)筒(tong)散發的(de)熱量(liang)，又(you)吸(xi)(xi)收中(zhong)層(ceng)滾(gun)筒(tong)的(de)熱量(liang)，同時又(you)延長了(le)干(gan)(gan)(gan)燥時間(jian)，物(wu)(wu)(wu)料(liao)(liao)在(zai)此(ci)達(da)到干(gan)(gan)(gan)燥狀態。物(wu)(wu)(wu)料(liao)(liao)行(xing)至(zhi)中(zhong)層(ceng)另(ling)一端而落入外層(ceng)，物(wu)(wu)(wu)料(liao)(liao)在(zai)外層(ceng)滾(gun)筒(tong)內(nei)(nei)呈(cheng)矩形(xing)多回路方式行(xing)進(jin)(jin)(jin)(jin)(jin)，達(da)到干(gan)(gan)(gan)燥效果(guo)的(de)物(wu)(wu)(wu)料(liao)(liao)在(zai)熱風作用下快速(su)行(xing)進(jin)(jin)(jin)(jin)(jin)排出滾(gun)筒(tong)，沒有(you)達(da)到干(gan)(gan)(gan)燥效果(guo)的(de)濕(shi)物(wu)(wu)(wu)料(liao)(liao)因自(zi)重而不(bu)能快速(su)行(xing)進(jin)(jin)(jin)(jin)(jin)，物(wu)(wu)(wu)料(liao)(liao)在(zai)此(ci)矩形(xing)抄(chao)板內(nei)(nei)進(jin)(jin)(jin)(jin)(jin)行(xing)充分干(gan)(gan)(gan)燥，由此(ci)完成干(gan)(gan)(gan)燥目(mu)的(de)。
