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。

工作原理(li)
XDS三筒(tong)(tong)(tong)烘(hong)干(gan)機是一種(zhong)水平安裝的組(zu)合(he)烘(hong)干(gan)機,筒(tong)(tong)(tong)體依靠4個驅動(dong)輪支撐并摩擦(ca)傳動(dong)筒(tong)(tong)(tong)體輪帶(dai)。筒(tong)(tong)(tong)體的入料(liao)(liao)(liao)(liao)端(duan)設有熱風爐(lu)裝置(zhi),當被(bei)烘(hong)干(gan)物(wu)料(liao)(liao)(liao)(liao)進(jin)入內筒(tong)(tong)(tong)后(hou),在內筒(tong)(tong)(tong)螺(luo)旋(xuan)揚(yang)料(liao)(liao)(liao)(liao)板推(tui)動(dong)下(xia)(xia)(xia)進(jin)入內筒(tong)(tong)(tong)斜軸(zhou)向(xiang)(xiang)揚(yang)料(liao)(liao)(liao)(liao)板,在揚(yang)料(liao)(liao)(liao)(liao)板帶(dai)動(dong)下(xia)(xia)(xia)形(xing)(xing)(xing)成斜軸(zhou)向(xiang)(xiang)均(jun)勻料(liao)(liao)(liao)(liao)幕同時推(tui)動(dong)物(wu)料(liao)(liao)(liao)(liao)前(qian)進(jin);物(wu)料(liao)(liao)(liao)(liao)進(jin)入中筒(tong)(tong)(tong)后(hou),在弧形(xing)(xing)(xing)斜徑向(xiang)(xiang)揚(yang)料(liao)(liao)(liao)(liao)板作用下(xia)(xia)(xia),形(xing)(xing)(xing)成斜徑向(xiang)(xiang)均(jun)勻前(qian)進(jin)料(liao)(liao)(liao)(liao)幕;物(wu)料(liao)(liao)(liao)(liao)進(jin)入外筒(tong)(tong)(tong)后(hou),在外筒(tong)(tong)(tong)多(duo)點(dian)徑向(xiang)(xiang)揚(yang)料(liao)(liao)(liao)(liao)板作用下(xia)(xia)(xia),形(xing)(xing)(xing)成多(duo)點(dian)徑向(xiang)(xiang)料(liao)(liao)(liao)(liao)幕,并向(xiang)(xiang)出(chu)(chu)料(liao)(liao)(liao)(liao)端(duan)移(yi)動(dong);出(chu)(chu)料(liao)(liao)(liao)(liao)端(duan)物(wu)料(liao)(liao)(liao)(liao)落在出(chu)(chu)料(liao)(liao)(liao)(liao)錐上(shang)進(jin)入出(chu)(chu)料(liao)(liao)(liao)(liao)螺(luo)旋(xuan)筒(tong)(tong)(tong),再落入出(chu)(chu)料(liao)(liao)(liao)(liao)罩排出(chu)(chu)。熱煙氣(qi)在揚(yang)料(liao)(liao)(liao)(liao)過(guo)程(cheng)中與物(wu)料(liao)(liao)(liao)(liao)充(chong)分進(jin)行熱交換,物(wu)料(liao)(liao)(liao)(liao)所(suo)含水份(fen)蒸發后(hou)被(bei)氣(qi)流帶(dai)走。
