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(ji)筒(tong)(tong)體部分由三個同軸(zhou)水平(ping)放置(zhi)的(de)內、中(zhong)、外筒(tong)(tong)套疊組(zu)成,這就使筒(tong)(tong)體的(de)截面(mian)得到充(chong)分的(de)利(li)用。其筒(tong)(tong)體外形總長度(du)約為(wei)與之相當的(de)單筒(tong)(tong)的(de)30-35%。從而大幅度(du)地減(jian)少占(zhan)地面(mian)積和廠房建筑面(mian)積。
該機(ji)的(de)支(zhi)承(cheng)裝置,是在(zai)(zai)外筒上(shang)輪(lun)帶與托輪(lun)支(zhi)承(cheng),由電機(ji)直接帶動托輪(lun)。通過托輪(lun)與輪(lun)帶摩擦,使筒體轉動。該機(ji)總體結構緊湊、合理、簡(jian)單,為(wei)便于磨損件的(de)檢修更換,在(zai)(zai)中間設計(ji)成軸向剖分式,用螺栓固定(ding)連接。
工作原理
物(wu)(wu)料(liao)(liao)由供(gong)料(liao)(liao)裝置(zhi)進(jin)(jin)入(ru)回轉滾(gun)(gun)筒的(de)內(nei)層(ceng)(ceng),實現順(shun)流(liu)烘干,物(wu)(wu)料(liao)(liao)在(zai)(zai)內(nei)層(ceng)(ceng)的(de)抄(chao)(chao)板下(xia)不斷抄(chao)(chao)起(qi)、散落(luo)(luo)呈螺旋(xuan)行(xing)(xing)(xing)進(jin)(jin)式實現熱(re)交換,物(wu)(wu)料(liao)(liao)移動至內(nei)層(ceng)(ceng)的(de)另一端(duan)進(jin)(jin)入(ru)中(zhong)(zhong)(zhong)層(ceng)(ceng),進(jin)(jin)行(xing)(xing)(xing)逆流(liu)烘干,物(wu)(wu)料(liao)(liao)在(zai)(zai)中(zhong)(zhong)(zhong)層(ceng)(ceng)不斷地被反復揚進(jin)(jin),呈進(jin)(jin)兩步退(tui)一步的(de)行(xing)(xing)(xing)進(jin)(jin)方式,物(wu)(wu)料(liao)(liao)在(zai)(zai)中(zhong)(zhong)(zhong)層(ceng)(ceng)既充(chong)分吸(xi)收(shou)內(nei)層(ceng)(ceng)滾(gun)(gun)筒散發的(de)熱(re)量(liang),又吸(xi)收(shou)中(zhong)(zhong)(zhong)層(ceng)(ceng)滾(gun)(gun)筒的(de)熱(re)量(liang),同時又延長了干燥(zao)時間,物(wu)(wu)料(liao)(liao)在(zai)(zai)此(ci)達(da)(da)到(dao)干燥(zao)狀態(tai)。物(wu)(wu)料(liao)(liao)行(xing)(xing)(xing)至中(zhong)(zhong)(zhong)層(ceng)(ceng)另一端(duan)而落(luo)(luo)入(ru)外層(ceng)(ceng),物(wu)(wu)料(liao)(liao)在(zai)(zai)外層(ceng)(ceng)滾(gun)(gun)筒內(nei)呈矩(ju)形多(duo)回路方式行(xing)(xing)(xing)進(jin)(jin),達(da)(da)到(dao)干燥(zao)效果的(de)物(wu)(wu)料(liao)(liao)在(zai)(zai)熱(re)風作用下(xia)快(kuai)速行(xing)(xing)(xing)進(jin)(jin)排出滾(gun)(gun)筒,沒有達(da)(da)到(dao)干燥(zao)效果的(de)濕物(wu)(wu)料(liao)(liao)因(yin)自(zi)重而不能快(kuai)速行(xing)(xing)(xing)進(jin)(jin),物(wu)(wu)料(liao)(liao)在(zai)(zai)此(ci)矩(ju)形抄(chao)(chao)板內(nei)進(jin)(jin)行(xing)(xing)(xing)充(chong)分干燥(zao),由此(ci)完成干燥(zao)目的(de)。
