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(gan)機產(chan)品概(gai)況及性(xing)能(neng)特點(dian)
1、技術(shu)含量高(gao),中、內筒自我保溫能力(li)強,熱能利用(yong)率(lv)高(gao),出(chu)口溫度低,大大延長了除塵(chen)器的使用(yong)壽命。
2、針對內、中、外筒不同區(qu)域(yu)分別采用不同技術的新型揚料(liao)裝置,可將揚料(liao)效(xiao)(xiao)率,有(you)效(xiao)(xiao)的消(xiao)除“風洞”帶來的熱(re)損失,增加物料(liao)與熱(re)氣流(liu)的接觸率,提高烘(hong)干效(xiao)(xiao)率。
3、占(zhan)地面積省(sheng),采用整體支架,安裝方便(bian),故障率少,維護方便(bian),運行(xing)可靠(kao),基礎投資省(sheng)。
4、進、出料(liao)裝置(zhi)采用特殊結構軟密(mi)封(feng),漏風(feng)率(lv)小。
5、工藝流(liu)程可采用順流(liu)或逆流(liu)。
6、優化的(de)結構(gou)設計、耐(nai)磨耐(nai)熱處理(li)技(ji)術,為烘干機的(de)長期、無故障(zhang)運行奠定了(le)基礎。
7、根(gen)據(ju)物(wu)料性質的不同,采(cai)用調速(su)電機或變(bian)頻器來合理調節筒體轉(zhuan)速(su)以提高(gao)烘干效率。
工作原理
XDS三筒(tong)(tong)(tong)烘(hong)干(gan)機(ji)是一(yi)種水平(ping)安(an)裝的(de)組(zu)合烘(hong)干(gan)機(ji),筒(tong)(tong)(tong)體依(yi)靠4個(ge)驅動(dong)(dong)輪支撐(cheng)并摩擦傳(chuan)動(dong)(dong)筒(tong)(tong)(tong)體輪帶。筒(tong)(tong)(tong)體的(de)入(ru)料(liao)(liao)(liao)(liao)端(duan)設有熱風爐(lu)裝置(zhi),當被烘(hong)干(gan)物(wu)料(liao)(liao)(liao)(liao)進(jin)(jin)入(ru)內(nei)筒(tong)(tong)(tong)后(hou),在(zai)(zai)內(nei)筒(tong)(tong)(tong)螺旋揚(yang)料(liao)(liao)(liao)(liao)板(ban)推動(dong)(dong)下(xia)進(jin)(jin)入(ru)內(nei)筒(tong)(tong)(tong)斜(xie)軸向(xiang)(xiang)(xiang)揚(yang)料(liao)(liao)(liao)(liao)板(ban),在(zai)(zai)揚(yang)料(liao)(liao)(liao)(liao)板(ban)帶動(dong)(dong)下(xia)形(xing)成斜(xie)軸向(xiang)(xiang)(xiang)均勻料(liao)(liao)(liao)(liao)幕同(tong)時推動(dong)(dong)物(wu)料(liao)(liao)(liao)(liao)前(qian)(qian)進(jin)(jin);物(wu)料(liao)(liao)(liao)(liao)進(jin)(jin)入(ru)中筒(tong)(tong)(tong)后(hou),在(zai)(zai)弧形(xing)斜(xie)徑向(xiang)(xiang)(xiang)揚(yang)料(liao)(liao)(liao)(liao)板(ban)作用下(xia),形(xing)成斜(xie)徑向(xiang)(xiang)(xiang)均勻前(qian)(qian)進(jin)(jin)料(liao)(liao)(liao)(liao)幕;物(wu)料(liao)(liao)(liao)(liao)進(jin)(jin)入(ru)外筒(tong)(tong)(tong)后(hou),在(zai)(zai)外筒(tong)(tong)(tong)多(duo)點徑向(xiang)(xiang)(xiang)揚(yang)料(liao)(liao)(liao)(liao)板(ban)作用下(xia),形(xing)成多(duo)點徑向(xiang)(xiang)(xiang)料(liao)(liao)(liao)(liao)幕,并向(xiang)(xiang)(xiang)出料(liao)(liao)(liao)(liao)端(duan)移(yi)動(dong)(dong);出料(liao)(liao)(liao)(liao)端(duan)物(wu)料(liao)(liao)(liao)(liao)落在(zai)(zai)出料(liao)(liao)(liao)(liao)錐上進(jin)(jin)入(ru)出料(liao)(liao)(liao)(liao)螺旋筒(tong)(tong)(tong),再落入(ru)出料(liao)(liao)(liao)(liao)罩排出。熱煙氣在(zai)(zai)揚(yang)料(liao)(liao)(liao)(liao)過(guo)程中與物(wu)料(liao)(liao)(liao)(liao)充分進(jin)(jin)行熱交(jiao)換,物(wu)料(liao)(liao)(liao)(liao)所含(han)水份蒸發后(hou)被氣流帶走。
