XDS型三筒烘干機主要用于烘干一定濕度范圍內顆粒物料如干粉砂漿行業中所用的黃砂；鑄造行業中的型砂；建材行業中的高爐礦渣、礦渣、粘土、煤、鐵粉等；化工行業中的不起化學反應、不怕高溫及污染的小顆粒等，烘干后的物料終水份可任意控制。沙子烘干機一般適應于顆粒狀物料。特別是烘干沙子、河沙、石英砂等烘干效果好。河沙沙子烘干機的優點是生產能力大、適用范圍廣、流量阻力小、操作上允許波動范圍較大、操作方便等。常用于烘干河沙、人工砂、石英砂、礦粉、煤渣等。
XDS型三筒烘干機產品概(gai)況及性能特點
1、技術含量(liang)高，中、內筒自我保溫能(neng)力強，熱(re)能(neng)利用率高，出口溫度低，大(da)大(da)延長了(le)除塵器的(de)使(shi)用壽命。
2、針對內、中、外筒(tong)不(bu)(bu)同區域分別采用(yong)不(bu)(bu)同技術的新型揚(yang)料裝置，可(ke)將揚(yang)料效率，有效的消除“風洞”帶來(lai)的熱損失，增(zeng)加物料與熱氣流的接(jie)觸率，提高烘(hong)干效率。
3、占地(di)面(mian)積省，采用(yong)整體支(zhi)架，安裝(zhuang)方便，故障率少(shao)，維護方便，運行可靠，基礎投資省。
4、進(jin)、出(chu)料(liao)裝置采(cai)用特殊(shu)結構軟密封(feng)，漏風率小。
5、工(gong)藝流(liu)程可采用(yong)順流(liu)或逆(ni)流(liu)。
6、優(you)化的結構設計、耐磨耐熱處理(li)技術，為烘干機的長期(qi)、無(wu)故障運(yun)行(xing)奠定了基礎。
7、根據物料性質的不同，采用調速電機或變頻器(qi)來合(he)理調節(jie)筒體轉速以提高烘(hong)干效(xiao)率。
工作原(yuan)理
XDS三筒(tong)(tong)(tong)烘干機是一種水平安(an)裝的組合烘干機，筒(tong)(tong)(tong)體(ti)依靠4個驅動(dong)輪支撐并(bing)摩(mo)擦傳動(dong)筒(tong)(tong)(tong)體(ti)輪帶(dai)。筒(tong)(tong)(tong)體(ti)的入(ru)料(liao)(liao)(liao)(liao)端設有熱風爐裝置，當(dang)被烘干物(wu)(wu)料(liao)(liao)(liao)(liao)進(jin)(jin)(jin)(jin)入(ru)內(nei)筒(tong)(tong)(tong)后，在內(nei)筒(tong)(tong)(tong)螺旋揚(yang)(yang)料(liao)(liao)(liao)(liao)板(ban)(ban)推動(dong)下進(jin)(jin)(jin)(jin)入(ru)內(nei)筒(tong)(tong)(tong)斜軸(zhou)向揚(yang)(yang)料(liao)(liao)(liao)(liao)板(ban)(ban)，在揚(yang)(yang)料(liao)(liao)(liao)(liao)板(ban)(ban)帶(dai)動(dong)下形(xing)成(cheng)斜軸(zhou)向均勻料(liao)(liao)(liao)(liao)幕同時(shi)推動(dong)物(wu)(wu)料(liao)(liao)(liao)(liao)前(qian)進(jin)(jin)(jin)(jin)；物(wu)(wu)料(liao)(liao)(liao)(liao)進(jin)(jin)(jin)(jin)入(ru)中(zhong)筒(tong)(tong)(tong)后，在弧形(xing)斜徑(jing)(jing)(jing)向揚(yang)(yang)料(liao)(liao)(liao)(liao)板(ban)(ban)作用下，形(xing)成(cheng)斜徑(jing)(jing)(jing)向均勻前(qian)進(jin)(jin)(jin)(jin)料(liao)(liao)(liao)(liao)幕；物(wu)(wu)料(liao)(liao)(liao)(liao)進(jin)(jin)(jin)(jin)入(ru)外筒(tong)(tong)(tong)后，在外筒(tong)(tong)(tong)多點(dian)徑(jing)(jing)(jing)向揚(yang)(yang)料(liao)(liao)(liao)(liao)板(ban)(ban)作用下，形(xing)成(cheng)多點(dian)徑(jing)(jing)(jing)向料(liao)(liao)(liao)(liao)幕，并(bing)向出(chu)(chu)料(liao)(liao)(liao)(liao)端移動(dong)；出(chu)(chu)料(liao)(liao)(liao)(liao)端物(wu)(wu)料(liao)(liao)(liao)(liao)落在出(chu)(chu)料(liao)(liao)(liao)(liao)錐上進(jin)(jin)(jin)(jin)入(ru)出(chu)(chu)料(liao)(liao)(liao)(liao)螺旋筒(tong)(tong)(tong)，再落入(ru)出(chu)(chu)料(liao)(liao)(liao)(liao)罩排出(chu)(chu)。熱煙氣在揚(yang)(yang)料(liao)(liao)(liao)(liao)過(guo)程中(zhong)與(yu)物(wu)(wu)料(liao)(liao)(liao)(liao)充(chong)分進(jin)(jin)(jin)(jin)行(xing)熱交換，物(wu)(wu)料(liao)(liao)(liao)(liao)所含(han)水份蒸發后被氣流帶(dai)走。
