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。

6、優化的(de)結構設計、耐磨耐熱處理技(ji)術,為(wei)烘干機的(de)長(chang)期、無故障運行奠定(ding)了基礎。
7、根據物料性質的不同,采用調速電機或(huo)變(bian)頻器來合理調節筒體(ti)轉速以提高烘干效(xiao)率。
工作原理
XDS三筒(tong)(tong)(tong)(tong)烘(hong)干(gan)機是一(yi)種水平安(an)裝的組合烘(hong)干(gan)機,筒(tong)(tong)(tong)(tong)體依靠4個驅(qu)動輪(lun)支(zhi)撐并摩擦(ca)傳動筒(tong)(tong)(tong)(tong)體輪(lun)帶(dai)。筒(tong)(tong)(tong)(tong)體的入(ru)(ru)料(liao)(liao)(liao)端設有熱風爐裝置,當被(bei)烘(hong)干(gan)物(wu)料(liao)(liao)(liao)進(jin)入(ru)(ru)內筒(tong)(tong)(tong)(tong)后,在(zai)內筒(tong)(tong)(tong)(tong)螺旋(xuan)揚(yang)料(liao)(liao)(liao)板(ban)推(tui)動下進(jin)入(ru)(ru)內筒(tong)(tong)(tong)(tong)斜(xie)(xie)軸(zhou)向(xiang)揚(yang)料(liao)(liao)(liao)板(ban),在(zai)揚(yang)料(liao)(liao)(liao)板(ban)帶(dai)動下形(xing)成斜(xie)(xie)軸(zhou)向(xiang)均勻(yun)(yun)料(liao)(liao)(liao)幕(mu)同(tong)時推(tui)動物(wu)料(liao)(liao)(liao)前進(jin);物(wu)料(liao)(liao)(liao)進(jin)入(ru)(ru)中筒(tong)(tong)(tong)(tong)后,在(zai)弧形(xing)斜(xie)(xie)徑(jing)(jing)向(xiang)揚(yang)料(liao)(liao)(liao)板(ban)作用(yong)下,形(xing)成斜(xie)(xie)徑(jing)(jing)向(xiang)均勻(yun)(yun)前進(jin)料(liao)(liao)(liao)幕(mu);物(wu)料(liao)(liao)(liao)進(jin)入(ru)(ru)外筒(tong)(tong)(tong)(tong)后,在(zai)外筒(tong)(tong)(tong)(tong)多(duo)點(dian)徑(jing)(jing)向(xiang)揚(yang)料(liao)(liao)(liao)板(ban)作用(yong)下,形(xing)成多(duo)點(dian)徑(jing)(jing)向(xiang)料(liao)(liao)(liao)幕(mu),并向(xiang)出(chu)料(liao)(liao)(liao)端移動;出(chu)料(liao)(liao)(liao)端物(wu)料(liao)(liao)(liao)落在(zai)出(chu)料(liao)(liao)(liao)錐上進(jin)入(ru)(ru)出(chu)料(liao)(liao)(liao)螺旋(xuan)筒(tong)(tong)(tong)(tong),再落入(ru)(ru)出(chu)料(liao)(liao)(liao)罩(zhao)排出(chu)。熱煙氣在(zai)揚(yang)料(liao)(liao)(liao)過(guo)程中與物(wu)料(liao)(liao)(liao)充(chong)分進(jin)行熱交(jiao)換,物(wu)料(liao)(liao)(liao)所含水份蒸發(fa)后被(bei)氣流帶(dai)走。
