產品(pin)概況
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。
產品結構
三(san)筒(tong)式烘(hong)(hong)(hong)干(gan)(gan)(gan)機(ji)(ji)是通過對單筒(tong)烘(hong)(hong)(hong)干(gan)(gan)(gan)機(ji)(ji)的單筒(tong)體(ti)改為套疊在一起的三(san)筒(tong),以(yi)縮短烘(hong)(hong)(hong)干(gan)(gan)(gan)機(ji)(ji)體(ti)的外(wai)形尺寸(cun)。該機(ji)(ji)工(gong)作時,物料(liao)和熱氣流(liu)依次進入內至外(wai)筒(tong)體(ti),在機(ji)(ji)體(ti)Z形往復折(zhe)流(liu)后(hou),充分利用熱能烘(hong)(hong)(hong)干(gan)(gan)(gan)物料(liao)后(hou)再卸出。
烘干機筒(tong)體(ti)部分由三個(ge)同(tong)軸水平放置的(de)內、中、外筒(tong)套疊組成(cheng),這就使筒(tong)體(ti)的(de)截面得到充分的(de)利用。其筒(tong)體(ti)外形總長(chang)度約為與之相當的(de)單筒(tong)的(de)30-35%。從而大(da)幅度地減少(shao)占地面積(ji)和廠房建筑(zhu)面積(ji)。
該機的支承裝置(zhi),是在外(wai)筒(tong)上(shang)輪帶與(yu)托輪支承,由電機直接帶動托輪。通過托輪與(yu)輪帶摩擦,使筒(tong)體轉動。該機總(zong)體結構(gou)緊湊(cou)、合理、簡單,為便于磨(mo)損件的檢修(xiu)更換,在中間設計成軸(zhou)向剖分式,用螺栓(shuan)固定連接。
工作原理(li)
物(wu)(wu)(wu)(wu)(wu)(wu)料(liao)由供料(liao)裝置進(jin)(jin)(jin)入回轉(zhuan)滾(gun)(gun)(gun)(gun)(gun)筒的(de)(de)(de)內(nei)(nei)(nei)(nei)層(ceng)(ceng)(ceng)(ceng),實現順流(liu)烘干(gan)(gan),物(wu)(wu)(wu)(wu)(wu)(wu)料(liao)在(zai)內(nei)(nei)(nei)(nei)層(ceng)(ceng)(ceng)(ceng)的(de)(de)(de)抄板(ban)下(xia)不斷(duan)抄起(qi)、散(san)落呈螺(luo)旋行(xing)(xing)進(jin)(jin)(jin)式實現熱交換,物(wu)(wu)(wu)(wu)(wu)(wu)料(liao)移動至(zhi)內(nei)(nei)(nei)(nei)層(ceng)(ceng)(ceng)(ceng)的(de)(de)(de)另一端(duan)進(jin)(jin)(jin)入中(zhong)層(ceng)(ceng)(ceng)(ceng),進(jin)(jin)(jin)行(xing)(xing)逆(ni)流(liu)烘干(gan)(gan),物(wu)(wu)(wu)(wu)(wu)(wu)料(liao)在(zai)中(zhong)層(ceng)(ceng)(ceng)(ceng)不斷(duan)地(di)被反(fan)復揚進(jin)(jin)(jin),呈進(jin)(jin)(jin)兩步退一步的(de)(de)(de)行(xing)(xing)進(jin)(jin)(jin)方式,物(wu)(wu)(wu)(wu)(wu)(wu)料(liao)在(zai)中(zhong)層(ceng)(ceng)(ceng)(ceng)既充分吸(xi)收內(nei)(nei)(nei)(nei)層(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)(gun)(gun)(gun)筒散(san)發的(de)(de)(de)熱量(liang),又吸(xi)收中(zhong)層(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)(gun)(gun)(gun)筒的(de)(de)(de)熱量(liang),同時(shi)又延長了(le)干(gan)(gan)燥(zao)(zao)時(shi)間(jian),物(wu)(wu)(wu)(wu)(wu)(wu)料(liao)在(zai)此達到干(gan)(gan)燥(zao)(zao)狀態。物(wu)(wu)(wu)(wu)(wu)(wu)料(liao)行(xing)(xing)至(zhi)中(zhong)層(ceng)(ceng)(ceng)(ceng)另一端(duan)而(er)落入外(wai)層(ceng)(ceng)(ceng)(ceng),物(wu)(wu)(wu)(wu)(wu)(wu)料(liao)在(zai)外(wai)層(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)(gun)(gun)(gun)筒內(nei)(nei)(nei)(nei)呈矩(ju)形多回路方式行(xing)(xing)進(jin)(jin)(jin),達到干(gan)(gan)燥(zao)(zao)效果的(de)(de)(de)物(wu)(wu)(wu)(wu)(wu)(wu)料(liao)在(zai)熱風作(zuo)用下(xia)快速行(xing)(xing)進(jin)(jin)(jin)排(pai)出滾(gun)(gun)(gun)(gun)(gun)筒,沒有達到干(gan)(gan)燥(zao)(zao)效果的(de)(de)(de)濕(shi)物(wu)(wu)(wu)(wu)(wu)(wu)料(liao)因自重而(er)不能快速行(xing)(xing)進(jin)(jin)(jin),物(wu)(wu)(wu)(wu)(wu)(wu)料(liao)在(zai)此矩(ju)形抄板(ban)內(nei)(nei)(nei)(nei)進(jin)(jin)(jin)行(xing)(xing)充分干(gan)(gan)燥(zao)(zao),由此完成干(gan)(gan)燥(zao)(zao)目(mu)的(de)(de)(de)。
