產品結構
三筒(tong)烘(hong)(hong)干(gan)(gan)機是通過對單(dan)筒(tong)烘(hong)(hong)干(gan)(gan)機的(de)單(dan)筒(tong)體(ti)(ti)改為套疊在(zai)一起的(de)三筒(tong)，以縮短烘(hong)(hong)干(gan)(gan)機體(ti)(ti)的(de)外形尺寸。該機工作時，物(wu)料和(he)熱氣流(liu)依次進入內至外筒(tong)體(ti)(ti)，在(zai)機體(ti)(ti)Z形往復折流(liu)后，充分(fen)利用熱能(neng)烘(hong)(hong)干(gan)(gan)物(wu)料后再卸出(chu)。
烘干機筒體(ti)部分由三個同軸水平放置的內(nei)、中、外(wai)(wai)筒套疊組(zu)成(cheng)，這(zhe)就使筒體(ti)的截面(mian)得到充(chong)分的利用(yong)。其筒體(ti)外(wai)(wai)形總長度約為與(yu)之相當(dang)的單筒的30-35%。從(cong)而大幅(fu)度地(di)減少(shao)占地(di)面(mian)積(ji)(ji)和(he)廠(chang)房建筑面(mian)積(ji)(ji)。
該機的(de)支承裝置，是在外筒(tong)(tong)上輪帶與(yu)托輪支承，由(you)電機直(zhi)接帶動(dong)托輪。通過托輪與(yu)輪帶摩擦，使筒(tong)(tong)體(ti)轉動(dong)。該機總體(ti)結構緊湊(cou)、合理、簡單，為便于磨損件的(de)檢修更換(huan)，在中(zhong)間設(she)計成軸向剖分式，用螺栓固定連接。
工(gong)作原理(li)
物(wu)(wu)(wu)料(liao)(liao)(liao)由(you)供(gong)料(liao)(liao)(liao)裝(zhuang)置進(jin)(jin)(jin)入(ru)回轉滾(gun)筒(tong)的(de)內(nei)(nei)(nei)(nei)層(ceng)(ceng)(ceng)(ceng),實(shi)現順流烘干(gan)(gan),物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)(zai)內(nei)(nei)(nei)(nei)層(ceng)(ceng)(ceng)(ceng)的(de)抄板(ban)下不斷(duan)抄起(qi)、散落(luo)呈螺旋(xuan)行(xing)進(jin)(jin)(jin)式(shi)實(shi)現熱交換，物(wu)(wu)(wu)料(liao)(liao)(liao)移動(dong)至內(nei)(nei)(nei)(nei)層(ceng)(ceng)(ceng)(ceng)的(de)另(ling)一(yi)端進(jin)(jin)(jin)入(ru)中層(ceng)(ceng)(ceng)(ceng)，進(jin)(jin)(jin)行(xing)逆流烘干(gan)(gan)，物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)(zai)中層(ceng)(ceng)(ceng)(ceng)不斷(duan)地被反(fan)復揚進(jin)(jin)(jin)，呈進(jin)(jin)(jin)兩步(bu)退一(yi)步(bu)的(de)行(xing)進(jin)(jin)(jin)方(fang)式(shi)，物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)(zai)中層(ceng)(ceng)(ceng)(ceng)既充分吸收內(nei)(nei)(nei)(nei)層(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)散發的(de)熱量，又(you)吸收中層(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)的(de)熱量，同(tong)時又(you)延長了干(gan)(gan)燥時間(jian)，物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)(zai)此達(da)到干(gan)(gan)燥狀態。物(wu)(wu)(wu)料(liao)(liao)(liao)行(xing)至中層(ceng)(ceng)(ceng)(ceng)另(ling)一(yi)端而落(luo)入(ru)外層(ceng)(ceng)(ceng)(ceng)，物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)(zai)外層(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)內(nei)(nei)(nei)(nei)呈矩(ju)形(xing)(xing)多回路方(fang)式(shi)行(xing)進(jin)(jin)(jin)，達(da)到干(gan)(gan)燥效果的(de)物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)(zai)熱風作(zuo)用(yong)下快速(su)行(xing)進(jin)(jin)(jin)排出滾(gun)筒(tong)，沒有達(da)到干(gan)(gan)燥效果的(de)濕物(wu)(wu)(wu)料(liao)(liao)(liao)因自(zi)重(zhong)而不能快速(su)行(xing)進(jin)(jin)(jin)，物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)(zai)此矩(ju)形(xing)(xing)抄板(ban)內(nei)(nei)(nei)(nei)進(jin)(jin)(jin)行(xing)充分干(gan)(gan)燥，由(you)此完成干(gan)(gan)燥目的(de)。
