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(gan)機產品(pin)概(gai)況及性能特點
1、技術含量(liang)高,中、內筒自我保(bao)溫能力(li)強,熱能利用(yong)率高,出口溫度低,大大延長了除塵(chen)器的使用(yong)壽命。
2、針對內(nei)、中、外(wai)筒不同區域分別采用不同技術的新型揚料裝置,可(ke)將揚料效(xiao)(xiao)率(lv),有效(xiao)(xiao)的消(xiao)除“風洞”帶來(lai)的熱損失,增加物料與熱氣(qi)流的接觸率(lv),提高烘干效(xiao)(xiao)率(lv)。
3、占(zhan)地面積省,采用(yong)整(zheng)體支架,安裝方便,故障率少,維護方便,運行可靠,基礎投資省。
4、進(jin)、出料裝置采用特殊(shu)結(jie)構軟(ruan)密封,漏風率(lv)小(xiao)。
5、工藝流(liu)(liu)程可采用順(shun)流(liu)(liu)或逆流(liu)(liu)。
6、優化的結構設(she)計、耐(nai)磨耐(nai)熱處理技術,為烘干機的長期、無故障(zhang)運行奠定了基礎。
7、根據物料性(xing)質的(de)不同,采用(yong)調(diao)速(su)電機或變(bian)頻器來合理調(diao)節筒(tong)體轉速(su)以提高烘干效率。
工(gong)作原理
XDS三筒(tong)(tong)(tong)烘干(gan)機是(shi)一種水平安裝的組(zu)合烘干(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。筒(tong)(tong)(tong)體的入(ru)(ru)料(liao)(liao)(liao)(liao)(liao)(liao)端設(she)有熱(re)風爐裝置(zhi),當被烘干(gan)物(wu)料(liao)(liao)(liao)(liao)(liao)(liao)進(jin)(jin)入(ru)(ru)內(nei)筒(tong)(tong)(tong)后,在(zai)內(nei)筒(tong)(tong)(tong)螺旋(xuan)揚(yang)料(liao)(liao)(liao)(liao)(liao)(liao)板(ban)推(tui)動(dong)下(xia)(xia)進(jin)(jin)入(ru)(ru)內(nei)筒(tong)(tong)(tong)斜軸(zhou)向(xiang)揚(yang)料(liao)(liao)(liao)(liao)(liao)(liao)板(ban),在(zai)揚(yang)料(liao)(liao)(liao)(liao)(liao)(liao)板(ban)帶動(dong)下(xia)(xia)形(xing)成(cheng)斜軸(zhou)向(xiang)均勻(yun)(yun)料(liao)(liao)(liao)(liao)(liao)(liao)幕同時推(tui)動(dong)物(wu)料(liao)(liao)(liao)(liao)(liao)(liao)前進(jin)(jin);物(wu)料(liao)(liao)(liao)(liao)(liao)(liao)進(jin)(jin)入(ru)(ru)中筒(tong)(tong)(tong)后,在(zai)弧形(xing)斜徑(jing)(jing)向(xiang)揚(yang)料(liao)(liao)(liao)(liao)(liao)(liao)板(ban)作用下(xia)(xia),形(xing)成(cheng)斜徑(jing)(jing)向(xiang)均勻(yun)(yun)前進(jin)(jin)料(liao)(liao)(liao)(liao)(liao)(liao)幕;物(wu)料(liao)(liao)(liao)(liao)(liao)(liao)進(jin)(jin)入(ru)(ru)外筒(tong)(tong)(tong)后,在(zai)外筒(tong)(tong)(tong)多點徑(jing)(jing)向(xiang)揚(yang)料(liao)(liao)(liao)(liao)(liao)(liao)板(ban)作用下(xia)(xia),形(xing)成(cheng)多點徑(jing)(jing)向(xiang)料(liao)(liao)(liao)(liao)(liao)(liao)幕,并向(xiang)出(chu)(chu)料(liao)(liao)(liao)(liao)(liao)(liao)端移動(dong);出(chu)(chu)料(liao)(liao)(liao)(liao)(liao)(liao)端物(wu)料(liao)(liao)(liao)(liao)(liao)(liao)落在(zai)出(chu)(chu)料(liao)(liao)(liao)(liao)(liao)(liao)錐(zhui)上進(jin)(jin)入(ru)(ru)出(chu)(chu)料(liao)(liao)(liao)(liao)(liao)(liao)螺旋(xuan)筒(tong)(tong)(tong),再落入(ru)(ru)出(chu)(chu)料(liao)(liao)(liao)(liao)(liao)(liao)罩排出(chu)(chu)。熱(re)煙氣在(zai)揚(yang)料(liao)(liao)(liao)(liao)(liao)(liao)過(guo)程中與物(wu)料(liao)(liao)(liao)(liao)(liao)(liao)充分進(jin)(jin)行熱(re)交(jiao)換(huan),物(wu)料(liao)(liao)(liao)(liao)(liao)(liao)所含水份(fen)蒸發后被氣流帶走。
