產品結構
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(hong)干機(ji)筒(tong)(tong)體部分由三個同軸(zhou)水平放置(zhi)的內、中、外(wai)筒(tong)(tong)套疊組成,這就使筒(tong)(tong)體的截(jie)面得到(dao)充分的利用(yong)。其(qi)筒(tong)(tong)體外(wai)形總長(chang)度(du)約為(wei)與之相當的單筒(tong)(tong)的30-35%。從(cong)而大幅度(du)地減少占地面積(ji)和(he)廠房建(jian)筑面積(ji)。
該機(ji)的(de)支承(cheng)裝置,是在(zai)外筒上輪帶與托輪支承(cheng),由電機(ji)直接(jie)帶動托輪。通過托輪與輪帶摩擦,使筒體(ti)轉動。該機(ji)總體(ti)結構緊(jin)湊、合理、簡單,為便于(yu)磨(mo)損件(jian)的(de)檢修更換,在(zai)中間設計成軸向剖分式,用螺栓固定(ding)連接(jie)。
工作原理
物(wu)(wu)(wu)料(liao)(liao)由(you)供料(liao)(liao)裝置(zhi)進(jin)入回(hui)轉滾筒(tong)的(de)(de)(de)內(nei)(nei)層(ceng)(ceng)(ceng),實(shi)現順流(liu)烘干(gan)(gan)(gan),物(wu)(wu)(wu)料(liao)(liao)在內(nei)(nei)層(ceng)(ceng)(ceng)的(de)(de)(de)抄(chao)板下不斷抄(chao)起、散落呈(cheng)螺(luo)旋行(xing)進(jin)式(shi)實(shi)現熱(re)交換,物(wu)(wu)(wu)料(liao)(liao)移動至(zhi)內(nei)(nei)層(ceng)(ceng)(ceng)的(de)(de)(de)另一(yi)端進(jin)入中(zhong)層(ceng)(ceng)(ceng),進(jin)行(xing)逆流(liu)烘干(gan)(gan)(gan),物(wu)(wu)(wu)料(liao)(liao)在中(zhong)層(ceng)(ceng)(ceng)不斷地被反復揚進(jin),呈(cheng)進(jin)兩步退一(yi)步的(de)(de)(de)行(xing)進(jin)方式(shi),物(wu)(wu)(wu)料(liao)(liao)在中(zhong)層(ceng)(ceng)(ceng)既充(chong)分吸(xi)收內(nei)(nei)層(ceng)(ceng)(ceng)滾筒(tong)散發的(de)(de)(de)熱(re)量(liang),又吸(xi)收中(zhong)層(ceng)(ceng)(ceng)滾筒(tong)的(de)(de)(de)熱(re)量(liang),同(tong)時又延長了干(gan)(gan)(gan)燥(zao)(zao)時間,物(wu)(wu)(wu)料(liao)(liao)在此(ci)(ci)達(da)到干(gan)(gan)(gan)燥(zao)(zao)狀態。物(wu)(wu)(wu)料(liao)(liao)行(xing)至(zhi)中(zhong)層(ceng)(ceng)(ceng)另一(yi)端而落入外(wai)層(ceng)(ceng)(ceng),物(wu)(wu)(wu)料(liao)(liao)在外(wai)層(ceng)(ceng)(ceng)滾筒(tong)內(nei)(nei)呈(cheng)矩(ju)形(xing)多回(hui)路方式(shi)行(xing)進(jin),達(da)到干(gan)(gan)(gan)燥(zao)(zao)效果的(de)(de)(de)物(wu)(wu)(wu)料(liao)(liao)在熱(re)風作用下快速(su)行(xing)進(jin)排出(chu)滾筒(tong),沒有(you)達(da)到干(gan)(gan)(gan)燥(zao)(zao)效果的(de)(de)(de)濕(shi)物(wu)(wu)(wu)料(liao)(liao)因自(zi)重(zhong)而不能快速(su)行(xing)進(jin),物(wu)(wu)(wu)料(liao)(liao)在此(ci)(ci)矩(ju)形(xing)抄(chao)板內(nei)(nei)進(jin)行(xing)充(chong)分干(gan)(gan)(gan)燥(zao)(zao),由(you)此(ci)(ci)完成干(gan)(gan)(gan)燥(zao)(zao)目(mu)的(de)(de)(de)。
