產品概(gai)況
回轉(zhuan)式(shi)三筒烘(hong)(hong)干(gan)機改進(jin)原單(dan)(dan)筒烘(hong)(hong)干(gan)機內部(bu)結(jie)構，增加(jia)入機前濕料(liao)的預烘(hong)(hong)干(gan)和延(yan)長濕料(liao)在(zai)機內烘(hong)(hong)干(gan)時間(jian)，再加(jia)上密封、保溫(wen)以及合理的配套措施，使(shi)烘(hong)(hong)干(gan)機生產能力與原單(dan)(dan)筒式(shi)烘(hong)(hong)干(gan)機相比，提高(gao)48-80%，單(dan)(dan)位容積(ji)蒸(zheng)發(fa)強度(du)可(ke)達120-180kg/m3，標準煤(mei)耗僅為6-8kg/t。其(qi)技術先進(jin)、運(yun)行(xing)參數合理，操作簡單(dan)(dan)可(ke)行(xing)，廣(guang)泛(fan)應(ying)用于各個行(xing)業(ye)的礦渣、粘土、煤(mei)。
產品(pin)結構
三筒(tong)烘(hong)(hong)干(gan)機(ji)是通過(guo)對單筒(tong)烘(hong)(hong)干(gan)機(ji)的(de)(de)單筒(tong)體(ti)(ti)改為套疊在一起的(de)(de)三筒(tong)，以(yi)縮短(duan)烘(hong)(hong)干(gan)機(ji)體(ti)(ti)的(de)(de)外形(xing)(xing)尺寸。該機(ji)工作時，物料和熱(re)氣流依次(ci)進入內至(zhi)外筒(tong)體(ti)(ti)，在機(ji)體(ti)(ti)Z形(xing)(xing)往復(fu)折流后(hou)，充分利用熱(re)能(neng)烘(hong)(hong)干(gan)物料后(hou)再卸(xie)出。
烘(hong)干機筒(tong)(tong)體(ti)(ti)部分由三個同軸水平放置的(de)內、中、外(wai)筒(tong)(tong)套疊組成，這(zhe)就使(shi)筒(tong)(tong)體(ti)(ti)的(de)截(jie)面得到充分的(de)利用。其(qi)筒(tong)(tong)體(ti)(ti)外(wai)形總長度約為與之(zhi)相當的(de)單筒(tong)(tong)的(de)30-35%。從(cong)而大幅度地減(jian)少(shao)占地面積和廠房(fang)建筑面積。
該機(ji)的支承裝置，是在外筒(tong)上輪(lun)帶(dai)與(yu)托輪(lun)支承，由電(dian)機(ji)直接帶(dai)動托輪(lun)。通過托輪(lun)與(yu)輪(lun)帶(dai)摩擦，使筒(tong)體轉動。該機(ji)總體結構緊湊、合理、簡單，為便(bian)于磨損件的檢修更(geng)換，在中(zhong)間設計成軸向(xiang)剖(pou)分式，用螺栓固定(ding)連接。
工作原理
物(wu)(wu)(wu)(wu)料(liao)(liao)由供料(liao)(liao)裝置進(jin)(jin)入(ru)回轉滾筒(tong)(tong)(tong)的(de)(de)內(nei)(nei)(nei)層(ceng)(ceng),實(shi)現順(shun)流(liu)烘干,物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)內(nei)(nei)(nei)層(ceng)(ceng)的(de)(de)抄板下不(bu)斷抄起、散落呈(cheng)(cheng)螺旋行(xing)(xing)(xing)進(jin)(jin)式(shi)實(shi)現熱(re)交換，物(wu)(wu)(wu)(wu)料(liao)(liao)移動至內(nei)(nei)(nei)層(ceng)(ceng)的(de)(de)另一端進(jin)(jin)入(ru)中(zhong)(zhong)層(ceng)(ceng)，進(jin)(jin)行(xing)(xing)(xing)逆(ni)流(liu)烘干，物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)中(zhong)(zhong)層(ceng)(ceng)不(bu)斷地被反復揚進(jin)(jin)，呈(cheng)(cheng)進(jin)(jin)兩步(bu)退一步(bu)的(de)(de)行(xing)(xing)(xing)進(jin)(jin)方式(shi)，物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)中(zhong)(zhong)層(ceng)(ceng)既充(chong)分吸收(shou)內(nei)(nei)(nei)層(ceng)(ceng)滾筒(tong)(tong)(tong)散發的(de)(de)熱(re)量，又吸收(shou)中(zhong)(zhong)層(ceng)(ceng)滾筒(tong)(tong)(tong)的(de)(de)熱(re)量，同(tong)時(shi)又延長了干燥(zao)時(shi)間(jian)，物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)此達(da)到干燥(zao)狀態。物(wu)(wu)(wu)(wu)料(liao)(liao)行(xing)(xing)(xing)至中(zhong)(zhong)層(ceng)(ceng)另一端而落入(ru)外層(ceng)(ceng)，物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)外層(ceng)(ceng)滾筒(tong)(tong)(tong)內(nei)(nei)(nei)呈(cheng)(cheng)矩形(xing)多回路方式(shi)行(xing)(xing)(xing)進(jin)(jin)，達(da)到干燥(zao)效果的(de)(de)物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)熱(re)風作(zuo)用下快速(su)行(xing)(xing)(xing)進(jin)(jin)排(pai)出滾筒(tong)(tong)(tong)，沒(mei)有達(da)到干燥(zao)效果的(de)(de)濕物(wu)(wu)(wu)(wu)料(liao)(liao)因(yin)自重而不(bu)能(neng)快速(su)行(xing)(xing)(xing)進(jin)(jin)，物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)此矩形(xing)抄板內(nei)(nei)(nei)進(jin)(jin)行(xing)(xing)(xing)充(chong)分干燥(zao)，由此完成干燥(zao)目的(de)(de)。
