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況及(ji)性能(neng)特點
1、技術(shu)含量高，中、內筒自(zi)我保溫能力強(qiang)，熱能利(li)用率高，出口(kou)溫度(du)低，大大延(yan)長了除塵器的使用壽命。
2、針對內、中(zhong)、外筒(tong)不同(tong)區域分(fen)別采用不同(tong)技術的新型揚料(liao)裝置，可(ke)將揚料(liao)效(xiao)率(lv)，有效(xiao)的消(xiao)除“風洞”帶(dai)來的熱(re)(re)損失，增加物料(liao)與熱(re)(re)氣流的接觸率(lv)，提(ti)高(gao)烘(hong)干(gan)效(xiao)率(lv)。
3、占(zhan)地面(mian)積省，采用(yong)整體(ti)支架，安裝方便，故障率少(shao)，維護方便，運(yun)行可靠，基礎投資省。
4、進(jin)、出料裝(zhuang)置(zhi)采用特殊結構(gou)軟(ruan)密(mi)封，漏風(feng)率小。
5、工藝流(liu)程可采用(yong)順流(liu)或逆(ni)流(liu)。
6、優(you)化的結構設計(ji)、耐磨耐熱(re)處理(li)技術，為烘(hong)干機的長期、無故障運(yun)行奠定了基礎。
7、根據物料性質的不同，采用(yong)調(diao)速(su)電機或變頻器來合理調(diao)節筒(tong)體(ti)轉速(su)以(yi)提高烘干效(xiao)率。
工(gong)作(zuo)原理
XDS三筒(tong)(tong)(tong)(tong)烘(hong)干機(ji)是一種(zhong)水平安裝的(de)組合烘(hong)干機(ji)，筒(tong)(tong)(tong)(tong)體依靠4個驅動(dong)(dong)輪支(zhi)撐并摩擦傳動(dong)(dong)筒(tong)(tong)(tong)(tong)體輪帶(dai)。筒(tong)(tong)(tong)(tong)體的(de)入(ru)(ru)料(liao)(liao)(liao)端(duan)設有熱(re)風(feng)爐裝置，當(dang)被(bei)烘(hong)干物(wu)料(liao)(liao)(liao)進(jin)(jin)入(ru)(ru)內筒(tong)(tong)(tong)(tong)后(hou)，在(zai)(zai)(zai)(zai)內筒(tong)(tong)(tong)(tong)螺旋(xuan)揚料(liao)(liao)(liao)板(ban)(ban)推動(dong)(dong)下進(jin)(jin)入(ru)(ru)內筒(tong)(tong)(tong)(tong)斜軸(zhou)向(xiang)(xiang)揚料(liao)(liao)(liao)板(ban)(ban)，在(zai)(zai)(zai)(zai)揚料(liao)(liao)(liao)板(ban)(ban)帶(dai)動(dong)(dong)下形(xing)成斜軸(zhou)向(xiang)(xiang)均(jun)勻料(liao)(liao)(liao)幕(mu)同時推動(dong)(dong)物(wu)料(liao)(liao)(liao)前(qian)進(jin)(jin)；物(wu)料(liao)(liao)(liao)進(jin)(jin)入(ru)(ru)中(zhong)筒(tong)(tong)(tong)(tong)后(hou)，在(zai)(zai)(zai)(zai)弧形(xing)斜徑向(xiang)(xiang)揚料(liao)(liao)(liao)板(ban)(ban)作(zuo)用下，形(xing)成斜徑向(xiang)(xiang)均(jun)勻前(qian)進(jin)(jin)料(liao)(liao)(liao)幕(mu)；物(wu)料(liao)(liao)(liao)進(jin)(jin)入(ru)(ru)外(wai)筒(tong)(tong)(tong)(tong)后(hou)，在(zai)(zai)(zai)(zai)外(wai)筒(tong)(tong)(tong)(tong)多(duo)點徑向(xiang)(xiang)揚料(liao)(liao)(liao)板(ban)(ban)作(zuo)用下，形(xing)成多(duo)點徑向(xiang)(xiang)料(liao)(liao)(liao)幕(mu)，并向(xiang)(xiang)出料(liao)(liao)(liao)端(duan)移動(dong)(dong)；出料(liao)(liao)(liao)端(duan)物(wu)料(liao)(liao)(liao)落在(zai)(zai)(zai)(zai)出料(liao)(liao)(liao)錐上進(jin)(jin)入(ru)(ru)出料(liao)(liao)(liao)螺旋(xuan)筒(tong)(tong)(tong)(tong)，再落入(ru)(ru)出料(liao)(liao)(liao)罩排出。熱(re)煙氣在(zai)(zai)(zai)(zai)揚料(liao)(liao)(liao)過(guo)程(cheng)中(zhong)與物(wu)料(liao)(liao)(liao)充(chong)分(fen)進(jin)(jin)行熱(re)交換(huan)，物(wu)料(liao)(liao)(liao)所含水份蒸發(fa)后(hou)被(bei)氣流帶(dai)走。
