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(tong)烘(hong)干機產品概況及(ji)性能特點
1、技術含量高(gao),中、內筒自(zi)我(wo)保溫能力(li)強,熱能利用率高(gao),出口溫度低(di),大大延長了除塵器的(de)使(shi)用壽命。
2、針(zhen)對(dui)內、中、外筒不(bu)同區域分別(bie)采用不(bu)同技(ji)術的新型揚料裝置,可將揚料效率(lv)(lv)(lv),有效的消除“風洞”帶來的熱損失,增加物料與熱氣流的接觸率(lv)(lv)(lv),提高烘干效率(lv)(lv)(lv)。
3、占(zhan)地面積省,采用(yong)整(zheng)體(ti)支架,安裝(zhuang)方便,故障(zhang)率少,維護方便,運行可(ke)靠(kao),基礎投資省。
4、進、出料(liao)裝置(zhi)采用特殊(shu)結構軟密封,漏風(feng)率小(xiao)。
5、工藝流(liu)程可采用順(shun)流(liu)或逆流(liu)。
6、優化的(de)結構設計、耐磨耐熱處理技術,為(wei)烘干機的(de)長期、無故障運(yun)行奠定了基礎。
7、根(gen)據(ju)物料(liao)性質的不同,采用(yong)調速(su)電(dian)機或變頻器來(lai)合理調節筒體轉(zhuan)速(su)以提高烘(hong)干效率。
工作原理
XDS三筒(tong)(tong)(tong)烘(hong)干機(ji)(ji)是一種(zhong)水平安裝(zhuang)的組合烘(hong)干機(ji)(ji),筒(tong)(tong)(tong)體依靠4個驅動(dong)(dong)輪支撐并摩(mo)擦傳動(dong)(dong)筒(tong)(tong)(tong)體輪帶(dai)。筒(tong)(tong)(tong)體的入料(liao)(liao)(liao)端(duan)(duan)(duan)設有熱風爐裝(zhuang)置,當被(bei)烘(hong)干物(wu)料(liao)(liao)(liao)進(jin)(jin)(jin)入內筒(tong)(tong)(tong)后,在(zai)(zai)內筒(tong)(tong)(tong)螺(luo)旋(xuan)揚料(liao)(liao)(liao)板推(tui)動(dong)(dong)下(xia)進(jin)(jin)(jin)入內筒(tong)(tong)(tong)斜(xie)(xie)軸向(xiang)揚料(liao)(liao)(liao)板,在(zai)(zai)揚料(liao)(liao)(liao)板帶(dai)動(dong)(dong)下(xia)形(xing)(xing)成(cheng)斜(xie)(xie)軸向(xiang)均勻料(liao)(liao)(liao)幕同時推(tui)動(dong)(dong)物(wu)料(liao)(liao)(liao)前進(jin)(jin)(jin);物(wu)料(liao)(liao)(liao)進(jin)(jin)(jin)入中筒(tong)(tong)(tong)后,在(zai)(zai)弧形(xing)(xing)斜(xie)(xie)徑(jing)向(xiang)揚料(liao)(liao)(liao)板作(zuo)用下(xia),形(xing)(xing)成(cheng)斜(xie)(xie)徑(jing)向(xiang)均勻前進(jin)(jin)(jin)料(liao)(liao)(liao)幕;物(wu)料(liao)(liao)(liao)進(jin)(jin)(jin)入外筒(tong)(tong)(tong)后,在(zai)(zai)外筒(tong)(tong)(tong)多點徑(jing)向(xiang)揚料(liao)(liao)(liao)板作(zuo)用下(xia),形(xing)(xing)成(cheng)多點徑(jing)向(xiang)料(liao)(liao)(liao)幕,并向(xiang)出料(liao)(liao)(liao)端(duan)(duan)(duan)移動(dong)(dong);出料(liao)(liao)(liao)端(duan)(duan)(duan)物(wu)料(liao)(liao)(liao)落在(zai)(zai)出料(liao)(liao)(liao)錐(zhui)上進(jin)(jin)(jin)入出料(liao)(liao)(liao)螺(luo)旋(xuan)筒(tong)(tong)(tong),再落入出料(liao)(liao)(liao)罩排出。熱煙氣在(zai)(zai)揚料(liao)(liao)(liao)過程中與物(wu)料(liao)(liao)(liao)充分進(jin)(jin)(jin)行熱交換,物(wu)料(liao)(liao)(liao)所含水份(fen)蒸發后被(bei)氣流帶(dai)走。
