產品結構

大型三筒烘干機是通過對單筒烘干機的單筒體改為套疊在一起的三筒，以縮短烘干機體的外形尺寸。該機工作時，物料和熱氣流依次進入內至外筒體，在機體Z形往復折流后，充分利用熱能烘干物料后再卸出。

烘干機筒(tong)體部分由三個(ge)同軸水(shui)平放置(zhi)的(de)內(nei)、中、外筒(tong)套疊組成，這就使筒(tong)體的(de)截面得到充(chong)分的(de)利用。其筒(tong)體外形總(zong)長度(du)(du)約為(wei)與(yu)之相(xiang)當的(de)單(dan)筒(tong)的(de)30-35%。從而大幅度(du)(du)地減少占(zhan)地面積和廠房建筑(zhu)面積。

該機(ji)的(de)支(zhi)承裝置(zhi)，是在外筒(tong)(tong)上輪帶(dai)與托輪支(zhi)承，由電(dian)機(ji)直接帶(dai)動(dong)托輪。通(tong)過(guo)托輪與輪帶(dai)摩擦，使筒(tong)(tong)體轉動(dong)。該機(ji)總體結構緊湊(cou)、合理、簡單(dan)，為便于磨損件的(de)檢修更換(huan)，在中間設計(ji)成(cheng)軸向(xiang)剖分(fen)式，用螺栓固(gu)定連接。

工(gong)作(zuo)原理

物(wu)(wu)(wu)料(liao)(liao)(liao)由供(gong)料(liao)(liao)(liao)裝置(zhi)進入回(hui)轉滾(gun)筒(tong)(tong)(tong)的(de)內層(ceng)(ceng),實現順(shun)流(liu)烘(hong)干(gan),物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)內層(ceng)(ceng)的(de)抄(chao)板(ban)下不斷抄(chao)起、散(san)落呈(cheng)螺(luo)旋行(xing)進式實現熱(re)交換，物(wu)(wu)(wu)料(liao)(liao)(liao)移(yi)動至內層(ceng)(ceng)的(de)另一(yi)端(duan)進入中(zhong)(zhong)層(ceng)(ceng)，進行(xing)逆流(liu)烘(hong)干(gan)，物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)中(zhong)(zhong)層(ceng)(ceng)不斷地被反復(fu)揚(yang)進，呈(cheng)進兩(liang)步退一(yi)步的(de)行(xing)進方式，物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)中(zhong)(zhong)層(ceng)(ceng)既充(chong)分(fen)吸收內層(ceng)(ceng)滾(gun)筒(tong)(tong)(tong)散(san)發的(de)熱(re)量，又吸收中(zhong)(zhong)層(ceng)(ceng)滾(gun)筒(tong)(tong)(tong)的(de)熱(re)量，同時又延長了(le)干(gan)燥(zao)時間，物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)此(ci)達到干(gan)燥(zao)狀態。物(wu)(wu)(wu)料(liao)(liao)(liao)行(xing)至中(zhong)(zhong)層(ceng)(ceng)另一(yi)端(duan)而落入外層(ceng)(ceng)，物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)外層(ceng)(ceng)滾(gun)筒(tong)(tong)(tong)內呈(cheng)矩形(xing)多回(hui)路方式行(xing)進，達到干(gan)燥(zao)效果的(de)物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)熱(re)風(feng)作用(yong)下快(kuai)速行(xing)進排出滾(gun)筒(tong)(tong)(tong)，沒有達到干(gan)燥(zao)效果的(de)濕物(wu)(wu)(wu)料(liao)(liao)(liao)因自重(zhong)而不能(neng)快(kuai)速行(xing)進，物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)此(ci)矩形(xing)抄(chao)板(ban)內進行(xing)充(chong)分(fen)干(gan)燥(zao)，由此(ci)完成(cheng)干(gan)燥(zao)目的(de)。
