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。

5、工(gong)藝流程(cheng)可采用順流或逆流。
6、優化的結構設計、耐磨耐熱處理(li)技(ji)術,為(wei)烘干機的長期(qi)、無故障運行奠(dian)定(ding)了(le)基礎。
7、根據物料性質的不(bu)同(tong),采(cai)用(yong)調速電(dian)機或變頻器來合理調節(jie)筒體轉速以(yi)提(ti)高烘干效率。
工作原理(li)
XDS三筒(tong)(tong)(tong)烘(hong)(hong)干(gan)(gan)(gan)機是一種水(shui)平(ping)安裝的組合(he)烘(hong)(hong)干(gan)(gan)(gan)機,筒(tong)(tong)(tong)體依靠4個(ge)驅(qu)動(dong)輪支撐并(bing)摩擦(ca)傳動(dong)筒(tong)(tong)(tong)體輪帶。筒(tong)(tong)(tong)體的入(ru)(ru)料(liao)(liao)端(duan)設有熱(re)風爐裝置,當(dang)被烘(hong)(hong)干(gan)(gan)(gan)物(wu)(wu)(wu)料(liao)(liao)進(jin)入(ru)(ru)內筒(tong)(tong)(tong)后(hou),在(zai)內筒(tong)(tong)(tong)螺(luo)旋揚(yang)料(liao)(liao)板(ban)(ban)推動(dong)下(xia)進(jin)入(ru)(ru)內筒(tong)(tong)(tong)斜(xie)軸向(xiang)揚(yang)料(liao)(liao)板(ban)(ban),在(zai)揚(yang)料(liao)(liao)板(ban)(ban)帶動(dong)下(xia)形成(cheng)斜(xie)軸向(xiang)均勻(yun)(yun)料(liao)(liao)幕(mu)(mu)同時推動(dong)物(wu)(wu)(wu)料(liao)(liao)前(qian)進(jin);物(wu)(wu)(wu)料(liao)(liao)進(jin)入(ru)(ru)中筒(tong)(tong)(tong)后(hou),在(zai)弧形斜(xie)徑向(xiang)揚(yang)料(liao)(liao)板(ban)(ban)作用下(xia),形成(cheng)斜(xie)徑向(xiang)均勻(yun)(yun)前(qian)進(jin)料(liao)(liao)幕(mu)(mu);物(wu)(wu)(wu)料(liao)(liao)進(jin)入(ru)(ru)外(wai)(wai)筒(tong)(tong)(tong)后(hou),在(zai)外(wai)(wai)筒(tong)(tong)(tong)多(duo)點徑向(xiang)揚(yang)料(liao)(liao)板(ban)(ban)作用下(xia),形成(cheng)多(duo)點徑向(xiang)料(liao)(liao)幕(mu)(mu),并(bing)向(xiang)出料(liao)(liao)端(duan)移動(dong);出料(liao)(liao)端(duan)物(wu)(wu)(wu)料(liao)(liao)落在(zai)出料(liao)(liao)錐上(shang)進(jin)入(ru)(ru)出料(liao)(liao)螺(luo)旋筒(tong)(tong)(tong),再落入(ru)(ru)出料(liao)(liao)罩排出。熱(re)煙(yan)氣在(zai)揚(yang)料(liao)(liao)過(guo)程中與物(wu)(wu)(wu)料(liao)(liao)充分(fen)進(jin)行(xing)熱(re)交換,物(wu)(wu)(wu)料(liao)(liao)所含水(shui)份蒸發后(hou)被氣流帶走。
