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性能特點
1、技術含量高，中、內筒自我保溫(wen)能力強，熱能利用率(lv)高，出口(kou)溫(wen)度低，大大延長(chang)了除塵(chen)器的(de)使用壽命。
2、針(zhen)對內、中、外筒不(bu)同區域分別采用不(bu)同技(ji)術的新型揚(yang)料(liao)(liao)裝置，可將揚(yang)料(liao)(liao)效(xiao)率，有效(xiao)的消(xiao)除“風洞”帶來的熱(re)損失(shi)，增加物料(liao)(liao)與熱(re)氣流的接觸(chu)率，提高烘干(gan)效(xiao)率。
3、占(zhan)地面積省，采用整體支架，安裝方便，故障率少，維護方便，運行可靠，基礎(chu)投資省。
4、進、出料裝置采用(yong)特殊結構軟密(mi)封，漏風率小。
5、工藝流程(cheng)可采用順流或逆流。
6、優化的結構(gou)設(she)計、耐(nai)磨耐(nai)熱處(chu)理(li)技術，為烘干機的長期、無故障運行奠(dian)定了基礎。
7、根據物料性質的不同，采用調(diao)(diao)速電(dian)機或變頻(pin)器來合理調(diao)(diao)節筒體(ti)轉速以提(ti)高烘干效率。
工作原理(li)
XDS三筒(tong)(tong)(tong)(tong)(tong)烘干機是(shi)一種水平(ping)安裝(zhuang)的組合烘干機，筒(tong)(tong)(tong)(tong)(tong)體(ti)依靠(kao)4個驅動(dong)(dong)輪(lun)支撐并摩(mo)擦傳動(dong)(dong)筒(tong)(tong)(tong)(tong)(tong)體(ti)輪(lun)帶。筒(tong)(tong)(tong)(tong)(tong)體(ti)的入(ru)(ru)料(liao)(liao)(liao)端(duan)設有熱(re)風爐(lu)裝(zhuang)置(zhi)，當被烘干物(wu)(wu)(wu)料(liao)(liao)(liao)進(jin)入(ru)(ru)內筒(tong)(tong)(tong)(tong)(tong)后(hou)，在(zai)內筒(tong)(tong)(tong)(tong)(tong)螺(luo)(luo)旋(xuan)揚(yang)(yang)料(liao)(liao)(liao)板(ban)推動(dong)(dong)下(xia)(xia)進(jin)入(ru)(ru)內筒(tong)(tong)(tong)(tong)(tong)斜軸向揚(yang)(yang)料(liao)(liao)(liao)板(ban)，在(zai)揚(yang)(yang)料(liao)(liao)(liao)板(ban)帶動(dong)(dong)下(xia)(xia)形成斜軸向均(jun)勻料(liao)(liao)(liao)幕同時(shi)推動(dong)(dong)物(wu)(wu)(wu)料(liao)(liao)(liao)前進(jin)；物(wu)(wu)(wu)料(liao)(liao)(liao)進(jin)入(ru)(ru)中筒(tong)(tong)(tong)(tong)(tong)后(hou)，在(zai)弧形斜徑向揚(yang)(yang)料(liao)(liao)(liao)板(ban)作用下(xia)(xia)，形成斜徑向均(jun)勻前進(jin)料(liao)(liao)(liao)幕；物(wu)(wu)(wu)料(liao)(liao)(liao)進(jin)入(ru)(ru)外筒(tong)(tong)(tong)(tong)(tong)后(hou)，在(zai)外筒(tong)(tong)(tong)(tong)(tong)多(duo)點徑向揚(yang)(yang)料(liao)(liao)(liao)板(ban)作用下(xia)(xia)，形成多(duo)點徑向料(liao)(liao)(liao)幕，并向出料(liao)(liao)(liao)端(duan)移動(dong)(dong)；出料(liao)(liao)(liao)端(duan)物(wu)(wu)(wu)料(liao)(liao)(liao)落在(zai)出料(liao)(liao)(liao)錐上進(jin)入(ru)(ru)出料(liao)(liao)(liao)螺(luo)(luo)旋(xuan)筒(tong)(tong)(tong)(tong)(tong)，再落入(ru)(ru)出料(liao)(liao)(liao)罩(zhao)排(pai)出。熱(re)煙氣在(zai)揚(yang)(yang)料(liao)(liao)(liao)過程(cheng)中與(yu)物(wu)(wu)(wu)料(liao)(liao)(liao)充分進(jin)行熱(re)交換，物(wu)(wu)(wu)料(liao)(liao)(liao)所含水份蒸發后(hou)被氣流帶走。
