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(xing)三筒烘干(gan)機(ji)產(chan)品(pin)概況及性能特(te)點
1、技術含(han)量高，中、內筒自(zi)我保溫能力強，熱能利用率高，出(chu)口溫度低，大大延(yan)長了除塵(chen)器(qi)的使用壽(shou)命。
2、針對內、中、外(wai)筒(tong)不同區域分(fen)別采用不同技術(shu)的新型揚(yang)料(liao)裝置(zhi)，可將(jiang)揚(yang)料(liao)效(xiao)率，有效(xiao)的消除“風洞(dong)”帶來的熱(re)損失，增加物料(liao)與熱(re)氣流(liu)的接觸率，提高烘干(gan)效(xiao)率。
3、占地(di)面(mian)積省，采用整體支(zhi)架，安(an)裝方(fang)便，故障(zhang)率(lv)少，維護方(fang)便，運行(xing)可(ke)靠，基礎投(tou)資省。
4、進、出料裝置(zhi)采用特殊結構軟(ruan)密(mi)封，漏風率小。
5、工藝流程可采用順(shun)流或逆(ni)流。
6、優化的結構設計、耐(nai)(nai)磨耐(nai)(nai)熱處理技術，為烘干機(ji)的長期、無故障運行奠定了基礎。
7、根據物料性質(zhi)的不同，采用調(diao)速(su)電機(ji)或變頻器來合理調(diao)節筒體轉速(su)以提高(gao)烘干(gan)效率(lv)。
工(gong)作(zuo)原理(li)
XDS三(san)筒(tong)(tong)(tong)(tong)烘(hong)干機是一種(zhong)水平安裝的(de)組合烘(hong)干機，筒(tong)(tong)(tong)(tong)體(ti)依靠4個驅動輪(lun)支撐并摩擦傳動筒(tong)(tong)(tong)(tong)體(ti)輪(lun)帶(dai)。筒(tong)(tong)(tong)(tong)體(ti)的(de)入(ru)料(liao)(liao)(liao)(liao)端(duan)設有熱風爐裝置，當被(bei)烘(hong)干物(wu)料(liao)(liao)(liao)(liao)進(jin)(jin)(jin)(jin)(jin)入(ru)內筒(tong)(tong)(tong)(tong)后(hou)，在內筒(tong)(tong)(tong)(tong)螺旋揚(yang)料(liao)(liao)(liao)(liao)板(ban)(ban)推動下進(jin)(jin)(jin)(jin)(jin)入(ru)內筒(tong)(tong)(tong)(tong)斜軸向(xiang)揚(yang)料(liao)(liao)(liao)(liao)板(ban)(ban)，在揚(yang)料(liao)(liao)(liao)(liao)板(ban)(ban)帶(dai)動下形(xing)成(cheng)斜軸向(xiang)均(jun)勻(yun)料(liao)(liao)(liao)(liao)幕同時推動物(wu)料(liao)(liao)(liao)(liao)前進(jin)(jin)(jin)(jin)(jin)；物(wu)料(liao)(liao)(liao)(liao)進(jin)(jin)(jin)(jin)(jin)入(ru)中筒(tong)(tong)(tong)(tong)后(hou)，在弧形(xing)斜徑向(xiang)揚(yang)料(liao)(liao)(liao)(liao)板(ban)(ban)作用(yong)下，形(xing)成(cheng)斜徑向(xiang)均(jun)勻(yun)前進(jin)(jin)(jin)(jin)(jin)料(liao)(liao)(liao)(liao)幕；物(wu)料(liao)(liao)(liao)(liao)進(jin)(jin)(jin)(jin)(jin)入(ru)外(wai)筒(tong)(tong)(tong)(tong)后(hou)，在外(wai)筒(tong)(tong)(tong)(tong)多(duo)點徑向(xiang)揚(yang)料(liao)(liao)(liao)(liao)板(ban)(ban)作用(yong)下，形(xing)成(cheng)多(duo)點徑向(xiang)料(liao)(liao)(liao)(liao)幕，并向(xiang)出料(liao)(liao)(liao)(liao)端(duan)移動；出料(liao)(liao)(liao)(liao)端(duan)物(wu)料(liao)(liao)(liao)(liao)落在出料(liao)(liao)(liao)(liao)錐上進(jin)(jin)(jin)(jin)(jin)入(ru)出料(liao)(liao)(liao)(liao)螺旋筒(tong)(tong)(tong)(tong)，再落入(ru)出料(liao)(liao)(liao)(liao)罩(zhao)排出。熱煙(yan)氣在揚(yang)料(liao)(liao)(liao)(liao)過(guo)程(cheng)中與(yu)物(wu)料(liao)(liao)(liao)(liao)充分進(jin)(jin)(jin)(jin)(jin)行熱交換，物(wu)料(liao)(liao)(liao)(liao)所含水份蒸發后(hou)被(bei)氣流帶(dai)走(zou)。
