散裝水泥輸送機-氣力輸灰系統-粉煤灰裝車輸送機
粉體氣力輸送機是利用壓(ya)縮空(kong)(kong)氣通過真空(kong)(kong)發(fa)生器產生高真空(kong)(kong)來輸(shu)送物(wu)(wu)料，不需要機械真空(kong)(kong)泵(beng)。具有結構簡單、體(ti)積小、免(mian)維護、噪音低(di)、控(kong)制方便、消除(chu)物(wu)(wu)料靜電等優點(dian)，符合(he)GMP要求。真空(kong)(kong)發(fa)生器產生的(de)高真空(kong)(kong)，防止輸(shu)送物(wu)(wu)料分層(ceng)，保證混合(he)物(wu)(wu)料成分的(de)均勻(yun)性。
當壓縮空氣(qi)(qi)(qi)供給真空發生器時，真空發生器產生負壓形成(cheng)真空氣(qi)(qi)(qi)流(liu)，物(wu)料(liao)被(bei)吸入吸嘴。出料(liao)閥又稱E型閥。作為接收器的(de)(de)輸送(song)閥是負壓系統的(de)(de)關鍵設備。一、其(qi)作用是通過(guo)送(song)料(liao)閥上(shang)的(de)(de)供氣(qi)(qi)(qi)閥和灰量(liang)調(diao)節裝(zhuang)置的(de)(de)工作，使(shi)灰斗內的(de)(de)灰渣與(yu)空氣(qi)(qi)(qi)均勻混合(he)，灰氣(qi)(qi)(qi)混合(he)物(wu)流(liu)動性*，可使(shi)其(qi)順利進入輸送(song)管(guan)路(lu)，保(bao)證輸送(song)系統高(gao)效平穩運行。物(wu)料(liao)輸送(song)采用氣(qi)(qi)(qi)路(lu)控制，其(qi)閥體和閥門具有良*的(de)(de)耐磨性。
氣力輸送系(xi)統的(de)氣源由負責(ze)的(de)壓(ya)力風(feng)機或真空提供。一般(ban)要求負責(ze)壓(ya)力在(zai)-0.6Mpa以下。由于通過(guo)風(feng)機的(de)氣流中不可(ke)避免地(di)含有一定(ding)量的(de)灰(hui)塵，因此要求負壓(ya)風(feng)機流道上的(de)零(ling)件應耐(nai)磨、耐(nai)腐蝕、密(mi)封防(fang)塵效果*。負壓(ya)風(feng)機一般(ban)布置在(zai)灰(hui)庫附近。氣力輸送系(xi)統的(de)控(kong)制一般(ban)采用PLC程序控(kong)制，可(ke)選擇模擬或CRT顯示。上位機進(jin)行數據處理，*自動運行，信號的(de)輸出、處理和聯網非常(chang)方便。
在(zai)設(she)(she)(she)計氣力(li)輸(shu)送(song)(song)(song)(song)(song)系統時(shi)，首先要保證能(neng)夠完成(cheng)預期的(de)(de)輸(shu)送(song)(song)(song)(song)(song)任務，同時(shi)合理(li)確定所用(yong)(yong)設(she)(she)(she)備的(de)(de)類(lei)型和容量，以(yi)及相關問題。設(she)(she)(she)計時(shi)不能(neng)只看(kan)設(she)(she)(she)備的(de)(de)造價，更(geng)重(zhong)要的(de)(de)是要綜(zong)合考(kao)慮物料的(de)(de)性質對質量的(de)(de)影響、輸(shu)送(song)(song)(song)(song)(song)量、輸(shu)送(song)(song)(song)(song)(song)距離、輸(shu)送(song)(song)(song)(song)(song)路線、難易程度等。以(yi)及運營管(guan)理(li)成(cheng)本等。例如，對于某些物料，各種設(she)(she)(she)備的(de)(de)條件都適合氣力(li)輸(shu)送(song)(song)(song)(song)(song)，但由(you)于物料中含(han)有大(da)量水(shui)分，具有粘性等原(yuan)因，不能(neng)用(yong)(yong)于氣力(li)輸(shu)送(song)(song)(song)(song)(song)。氣力(li)輸(shu)送(song)(song)(song)(song)(song)，即使機械輸(shu)送(song)(song)(song)(song)(song)設(she)(she)(she)備成(cheng)本高，也(ye)必須(xu)選擇機械輸(shu)送(song)(song)(song)(song)(song)方式。還有這樣一種情況，在(zai)輸(shu)送(song)(song)(song)(song)(song)某些物料的(de)(de)時(shi)候，比如把石(shi)灰石(shi)粉(fen)輸(shu)送(song)(song)(song)(song)(song)到循環流化(hua)床鍋(guo)爐(lu)前(qian)的(de)(de)儲料倉時(shi)，氣力(li)輸(shu)送(song)(song)(song)(song)(song)需(xu)要的(de)(de)功率較(jiao)大(da)，一開始運行成(cheng)本比較(jiao)高乍(zha)看(kan)之下，但從系統合理(li)性或生(sheng)產工藝上來說，還是采用(yong)(yong)氣力(li)輸(shu)送(song)(song)(song)(song)(song)為*。
