產品概況(kuang)
回轉式三筒烘干機改進原單筒烘干機內部結構，增加入機前濕料的預烘干和延長濕料在機內烘干時間，再加上密封、保溫以及合理的配套措施，使烘干機生產能力與原單筒式烘干機相比，提高48-80%，單位容積蒸發強度可達120-180kg/m3，標準煤耗僅為6-8kg/t。其技術先進、運行參數合理，操作簡單可行，廣泛應用于各個行業的礦渣、粘土、煤。
產品(pin)結構
三筒式烘干機(ji)(ji)是通過對單筒烘干機(ji)(ji)的單筒體改(gai)為套疊在(zai)一(yi)起的三筒，以縮短烘干機(ji)(ji)體的外形尺寸。該機(ji)(ji)工作時，物(wu)料(liao)和(he)熱氣流(liu)依次進入(ru)內(nei)至(zhi)外筒體，在(zai)機(ji)(ji)體Z形往復(fu)折流(liu)后，充分利用熱能(neng)烘干物(wu)料(liao)后再卸出。
烘(hong)干機(ji)筒(tong)體部分由三個(ge)同軸水平放(fang)置的(de)內、中、外筒(tong)套疊組成，這就使(shi)筒(tong)體的(de)截面(mian)得到(dao)充分的(de)利用。其筒(tong)體外形總長度(du)(du)約(yue)為(wei)與之相(xiang)當的(de)單筒(tong)的(de)30-35%。從而大幅度(du)(du)地減少占地面(mian)積和廠房建筑(zhu)面(mian)積。
該機的(de)支承裝(zhuang)置，是在(zai)(zai)外筒上輪(lun)(lun)(lun)帶(dai)與托輪(lun)(lun)(lun)支承，由電機直(zhi)接帶(dai)動托輪(lun)(lun)(lun)。通過托輪(lun)(lun)(lun)與輪(lun)(lun)(lun)帶(dai)摩(mo)擦，使筒體轉動。該機總體結構緊湊、合(he)理(li)、簡單，為便于磨損件的(de)檢修(xiu)更換，在(zai)(zai)中(zhong)間設計(ji)成軸向(xiang)剖分(fen)式，用螺栓固定連接。
工作原理(li)
物(wu)(wu)料(liao)(liao)由供料(liao)(liao)裝(zhuang)置進(jin)(jin)入(ru)回(hui)轉(zhuan)滾(gun)(gun)筒(tong)(tong)的(de)(de)(de)內(nei)(nei)層(ceng)(ceng)(ceng)(ceng),實(shi)現順流(liu)烘干,物(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)內(nei)(nei)層(ceng)(ceng)(ceng)(ceng)的(de)(de)(de)抄(chao)(chao)板下不(bu)斷抄(chao)(chao)起、散(san)落呈(cheng)螺旋行(xing)(xing)(xing)(xing)(xing)進(jin)(jin)式(shi)實(shi)現熱交換，物(wu)(wu)料(liao)(liao)移動(dong)至(zhi)(zhi)內(nei)(nei)層(ceng)(ceng)(ceng)(ceng)的(de)(de)(de)另一端進(jin)(jin)入(ru)中(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)，進(jin)(jin)行(xing)(xing)(xing)(xing)(xing)逆流(liu)烘干，物(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)中(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)不(bu)斷地被(bei)反復(fu)揚進(jin)(jin)，呈(cheng)進(jin)(jin)兩(liang)步退一步的(de)(de)(de)行(xing)(xing)(xing)(xing)(xing)進(jin)(jin)方(fang)式(shi)，物(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)中(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)既充分(fen)吸(xi)收內(nei)(nei)層(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)(tong)散(san)發的(de)(de)(de)熱量，又吸(xi)收中(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)(tong)的(de)(de)(de)熱量，同時又延長(chang)了干燥時間，物(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)此達到干燥狀態。物(wu)(wu)料(liao)(liao)行(xing)(xing)(xing)(xing)(xing)至(zhi)(zhi)中(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)另一端而落入(ru)外(wai)層(ceng)(ceng)(ceng)(ceng)，物(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)外(wai)層(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)(tong)內(nei)(nei)呈(cheng)矩(ju)形多回(hui)路方(fang)式(shi)行(xing)(xing)(xing)(xing)(xing)進(jin)(jin)，達到干燥效果(guo)的(de)(de)(de)物(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)熱風作用下快速(su)行(xing)(xing)(xing)(xing)(xing)進(jin)(jin)排出滾(gun)(gun)筒(tong)(tong)，沒有達到干燥效果(guo)的(de)(de)(de)濕(shi)物(wu)(wu)料(liao)(liao)因(yin)自(zi)重而不(bu)能(neng)快速(su)行(xing)(xing)(xing)(xing)(xing)進(jin)(jin)，物(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)此矩(ju)形抄(chao)(chao)板內(nei)(nei)進(jin)(jin)行(xing)(xing)(xing)(xing)(xing)充分(fen)干燥，由此完(wan)成干燥目的(de)(de)(de)。
