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(san)筒烘干機產品概況及性能特點
1、技術含量高,中、內筒自我保溫(wen)能力(li)強,熱能利用率(lv)高,出口(kou)溫(wen)度低(di),大大延長了(le)除(chu)塵(chen)器的使用壽命。
2、針(zhen)對內、中、外(wai)筒不(bu)(bu)同區域分(fen)別(bie)采(cai)用不(bu)(bu)同技術的新型揚料(liao)裝置,可將揚料(liao)效(xiao)率(lv)(lv),有(you)效(xiao)的消(xiao)除“風洞”帶來的熱損失,增加物料(liao)與熱氣流的接觸率(lv)(lv),提高烘(hong)干(gan)效(xiao)率(lv)(lv)。
3、占地面積省,采用(yong)整(zheng)體支(zhi)架,安(an)裝方便,故障率少,維(wei)護(hu)方便,運行可(ke)靠,基礎投資省。
4、進、出料(liao)裝置(zhi)采用特(te)殊結構軟密(mi)封,漏風率小。
5、工藝流程(cheng)可采用(yong)順流或(huo)逆(ni)流。
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(gu)障運行奠定了基(ji)礎(chu)。
7、根據(ju)物料(liao)性質的不同,采用調速電(dian)機或變頻器(qi)來合理(li)調節筒體(ti)轉速以(yi)提高烘(hong)干效率。
工作原理
XDS三筒(tong)(tong)烘干機(ji)是(shi)一種水平(ping)安裝的組(zu)合烘干機(ji),筒(tong)(tong)體(ti)依靠(kao)4個驅(qu)動(dong)(dong)輪支撐并摩擦傳動(dong)(dong)筒(tong)(tong)體(ti)輪帶。筒(tong)(tong)體(ti)的入(ru)(ru)料(liao)(liao)(liao)(liao)端設有熱風爐裝置,當被烘干物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)進(jin)入(ru)(ru)內(nei)筒(tong)(tong)后,在內(nei)筒(tong)(tong)螺旋揚(yang)(yang)(yang)料(liao)(liao)(liao)(liao)板推動(dong)(dong)下(xia)進(jin)入(ru)(ru)內(nei)筒(tong)(tong)斜(xie)(xie)軸向(xiang)(xiang)揚(yang)(yang)(yang)料(liao)(liao)(liao)(liao)板,在揚(yang)(yang)(yang)料(liao)(liao)(liao)(liao)板帶動(dong)(dong)下(xia)形(xing)成(cheng)斜(xie)(xie)軸向(xiang)(xiang)均勻料(liao)(liao)(liao)(liao)幕(mu)同時推動(dong)(dong)物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)前進(jin);物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)進(jin)入(ru)(ru)中筒(tong)(tong)后,在弧形(xing)斜(xie)(xie)徑(jing)向(xiang)(xiang)揚(yang)(yang)(yang)料(liao)(liao)(liao)(liao)板作用(yong)下(xia),形(xing)成(cheng)斜(xie)(xie)徑(jing)向(xiang)(xiang)均勻前進(jin)料(liao)(liao)(liao)(liao)幕(mu);物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)進(jin)入(ru)(ru)外(wai)筒(tong)(tong)后,在外(wai)筒(tong)(tong)多(duo)點(dian)徑(jing)向(xiang)(xiang)揚(yang)(yang)(yang)料(liao)(liao)(liao)(liao)板作用(yong)下(xia),形(xing)成(cheng)多(duo)點(dian)徑(jing)向(xiang)(xiang)料(liao)(liao)(liao)(liao)幕(mu),并向(xiang)(xiang)出(chu)(chu)料(liao)(liao)(liao)(liao)端移動(dong)(dong);出(chu)(chu)料(liao)(liao)(liao)(liao)端物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)落在出(chu)(chu)料(liao)(liao)(liao)(liao)錐上(shang)進(jin)入(ru)(ru)出(chu)(chu)料(liao)(liao)(liao)(liao)螺旋筒(tong)(tong),再(zai)落入(ru)(ru)出(chu)(chu)料(liao)(liao)(liao)(liao)罩排出(chu)(chu)。熱煙氣在揚(yang)(yang)(yang)料(liao)(liao)(liao)(liao)過程中與(yu)物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)充分進(jin)行熱交換,物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)所含水份蒸(zheng)發后被氣流帶走。
