海南粉體氣力輸送機的系統分類-如何配置氣力輸送機?系統
粉體氣力輸送機系統分類有哪些？
一般由(you)受(shou)料(liao)(liao)器(qi)(qi)(qi)(如喉管、吸嘴、發送器(qi)(qi)(qi)等)、輸送管、風(feng)(feng)(feng)管、分(fen)離(li)器(qi)(qi)(qi)(常用(yong)(yong)(yong)的(de)有容積式(shi)(shi)和旋風(feng)(feng)(feng)式(shi)(shi)兩種(zhong)(zhong))、鎖氣器(qi)(qi)(qi)(常用(yong)(yong)(yong)的(de)有翻板式(shi)(shi)和回轉(zhuan)式(shi)(shi)兩種(zhong)(zhong)，既(ji)可作(zuo)為(wei)喂料(liao)(liao)器(qi)(qi)(qi)，又可作(zuo)為(wei))、和風(feng)(feng)(feng)機(ji)(ji)(ji)(如離(li)心(xin)式(shi)(shi)風(feng)(feng)(feng)機(ji)(ji)(ji)、鼓風(feng)(feng)(feng)機(ji)(ji)(ji)、水環真(zhen)空(kong)泵、空(kong)壓(ya)機(ji)(ji)(ji)等)等設(she)備和部件(jian)組(zu)成。受(shou)料(liao)(liao)器(qi)(qi)(qi)的(de)作(zuo)用(yong)(yong)(yong)是進人物(wu)料(liao)(liao)，造成合適(shi)的(de)料(liao)(liao)氣比，使(shi)物(wu)料(liao)(liao)啟動、加速。分(fen)離(li)器(qi)(qi)(qi)的(de)作(zuo)用(yong)(yong)(yong)是將物(wu)料(liao)(liao)與空(kong)氣分(fen)離(li)，并對物(wu)料(liao)(liao)進行分(fen)選。鎖氣器(qi)(qi)(qi)的(de)作(zuo)用(yong)(yong)(yong)是均勻(yun)供料(liao)(liao)或(huo)卸料(liao)(liao)，同時(shi)阻止(zhi)空(kong)氣漏人。風(feng)(feng)(feng)機(ji)(ji)(ji)的(de)作(zuo)用(yong)(yong)(yong)是為(wei)系統提供動力(li)。真(zhen)空(kong)吸送系統常用(yong)(yong)(yong)高壓(ya)離(li)心(xin)風(feng)(feng)(feng)機(ji)(ji)(ji)或(huo)水環真(zhen)空(kong)泵；而壓(ya)送系統則(ze)需用(yong)(yong)(yong)羅茨鼓風(feng)(feng)(feng)機(ji)(ji)(ji)或(huo)空(kong)壓(ya)機(ji)(ji)(ji)。
1.吸送式氣力輸送機系統
氣源設(she)備在系(xi)統的末(mo)端。當(dang)風機(ji)運轉后，整個系(xi)統形(xing)成負壓，管道(dao)內外產生壓差(cha)，空氣被(bei)吸(xi)入(ru)輸料管道(dao)。物(wu)料也(ye)從吸(xi)嘴被(bei)空氣帶入(ru)管道(dao)，通(tong)(tong)過(guo)管道(dao)進入(ru)分離收集(ji)器，然(ran)后物(wu)料通(tong)(tong)過(guo)進入(ru)儲料罐，而空氣則通(tong)(tong)過(guo)收集(ji)器中的過(guo)濾設(she)備從風機(ji)中排除
2.壓送式氣(qi)力輸送系統(tong)
氣源(yuan)在輸送(song)設(she)備的前(qian)端，因此(ci)，物(wu)(wu)料進(jin)(jin)(jin)入輸送(song)罐(guan)B須使(shi)用有密(mi)封壓力的供料裝置(zhi)。一般在低(di)壓時，使(shi)用的是旋轉(zhuan)；高壓時，使(shi)用流化(hua)罐(guan)。物(wu)(wu)料通過(guo)閥門(men)進(jin)(jin)(jin)入輸送(song)罐(guan)，再通過(guo)蝶閥進(jin)(jin)(jin)入流化(hua)罐(guan)，通過(guo)量(liang)位儀或者稱量(liang)秤控制其進(jin)(jin)(jin)料量(liang)，當達到要求(qiu)后(hou)，蝶閥關閉，通入空(kong)氣使(shi)物(wu)(wu)料流態化(hua)，開啟(qi)流態化(hua)下(xia)端的閥門(men)，通過(guo)空(kong)氣將物(wu)(wu)料和空(kong)氣的混合物(wu)(wu)壓入管道。
