一．工(gong)作原理  

旋(xuan)流(liu)式(shi)沉(chen)砂(sha)(sha)(sha)池除(chu)砂(sha)(sha)(sha)機在驅動(dong)裝(zhuang)置的驅動(dong)下(xia)，池中(zhong)攪拌葉輪旋(xuan)轉(zhuan)產生離心力，使(shi)水中(zhong)的砂(sha)(sha)(sha)粒沿壁及(ji)池底斜坡(po)集(ji)于(yu)池底的集(ji)砂(sha)(sha)(sha)斗中(zhong)，同時將砂(sha)(sha)(sha)粒上粘附(fu)的有機物分(fen)離下(xia)來。沉(chen)集(ji)于(yu)砂(sha)(sha)(sha)斗內砂(sha)(sha)(sha)粒通過氣提或砂(sha)(sha)(sha)泵提升至池外，作進一步砂(sha)(sha)(sha)水分(fen)離。 

 二．結構特點 

旋流(liu)式(shi)沉砂(sha)除砂(sha)機是(shi)一種新型的砂(sha)水分(fen)離(li)工藝。

該產(chan)(chan)品主要(yao)由(you)驅(qu)(qu)動(dong)(dong)裝(zhuang)置、攪(jiao)拌(ban)(ban)機(ji)構、洗砂(sha)(sha)(sha)(sha)(sha)系統(tong)、吸砂(sha)(sha)(sha)(sha)(sha)系統(tong)、電控(kong)系統(tong)等部分(fen)(fen)組成。主要(yao)應用于(yu)(yu)給排水(shui)(shui)工程(cheng)中(zhong)(zhong)去除(chu)水(shui)(shui)中(zhong)(zhong)的(de)砂(sha)(sha)(sha)(sha)(sha)粒及(ji)附在砂(sha)(sha)(sha)(sha)(sha)粒上(shang)(shang)的(de)有(you)機(ji)物(wu)，可有(you)效地分(fen)(fen)離(li)直徑大于(yu)(yu)0.2mm的(de)砂(sha)(sha)(sha)(sha)(sha)粒。  旋流式沉(chen)砂(sha)(sha)(sha)(sha)(sha)池(chi)除(chu)砂(sha)(sha)(sha)(sha)(sha)機(ji)在驅(qu)(qu)動(dong)(dong)裝(zhuang)置的(de)驅(qu)(qu)動(dong)(dong)下，池(chi)中(zhong)(zhong)攪(jiao)拌(ban)(ban)葉(xie)輪(lun)旋轉(zhuan)產(chan)(chan)生離(li)心(xin)力，使水(shui)(shui)中(zhong)(zhong)的(de)砂(sha)(sha)(sha)(sha)(sha)粒沿壁(bi)及(ji)池(chi)底斜坡集(ji)于(yu)(yu)池(chi)底的(de)集(ji)砂(sha)(sha)(sha)(sha)(sha)斗中(zhong)(zhong)，同時(shi)將(jiang)砂(sha)(sha)(sha)(sha)(sha)粒上(shang)(shang)粘(zhan)附的(de)有(you)機(ji)物(wu)分(fen)(fen)離(li)下來。沉(chen)集(ji)于(yu)(yu)砂(sha)(sha)(sha)(sha)(sha)斗內砂(sha)(sha)(sha)(sha)(sha)粒通過氣(qi)提(ti)泵或砂(sha)(sha)(sha)(sha)(sha)泵提(ti)升(sheng)至池(chi)外，作進一步砂(sha)(sha)(sha)(sha)(sha)水(shui)(shui)分(fen)(fen)離(li)。由(you)于(yu)(yu)葉(xie)輪(lun)槳板向上(shang)(shang)傾(qing)(qing)斜，旋轉(zhuan)時(shi)使池(chi)中(zhong)(zhong)污(wu)水(shui)(shui)作螺(luo)旋運動(dong)(dong)，加上(shang)(shang)因污(wu)水(shui)(shui)切向進入，產(chan)(chan)生與葉(xie)輪(lun)旋向一致的(de)旋流，池(chi)中(zhong)(zhong)的(de)污(wu)水(shui)(shui)形(xing)成渦(wo)螺(luo)流態(tai)。在適當的(de)葉(xie)槳傾(qing)(qing)角和線速度(du)(du)(du)條件下，污(wu)水(shui)(shui)中(zhong)(zhong)的(de)砂(sha)(sha)(sha)(sha)(sha)粒將(jiang)受(shou)到沖刷(shua)并(bing)仍(reng)保持好的(de)沉(chen)降效果，而原(yuan)來附著在砂(sha)(sha)(sha)(sha)(sha)粒上(shang)(shang)的(de)有(you)機(ji)物(wu)以(yi)及(ji)重度(du)(du)(du)小的(de)物(wu)質將(jiang)隨污(wu)水(shui)(shui)一同流出旋流池(chi)。另外，由(you)于(yu)(yu)葉(xie)輪(lun)旋轉(zhuan)，減(jian)少了旋流池(chi)因進水(shui)(shui)量變化導致流態(tai)變化的(de)敏感程(cheng)度(du)(du)(du)，保證(zheng)了沉(chen)砂(sha)(sha)(sha)(sha)(sha)池(chi)穩(wen)定(ding)、出砂(sha)(sha)(sha)(sha)(sha)的(de)有(you)機(ji)成分(fen)(fen)含量低等特(te)點。  

三．操(cao)作要點

1．本設備進氣(qi)管(guan)(guan)(guan)路(lu)為2條：一(yi)條是洗砂管(guan)(guan)(guan)、一(yi)條是吸砂管(guan)(guan)(guan)。為了保證(zheng)有足夠的(de)吸砂力度，在(zai)吸砂時要停止洗砂工作(zuo)。一(yi)般采用人(ren)工操作(zuo)，也可以在(zai)氣(qi)路(lu)管(guan)(guan)(guan)道上(shang)接上(shang)電(dian)磁閥和電(dian)控(kong)箱連(lian)接進行時間(jian)控(kong)制和PLC控(kong)制。如果(guo)不(bu)需要洗砂可以關掉(diao)洗砂管(guan)(guan)(guan)只進行提砂工作(zuo)。

2．本設備(bei)提砂(sha)控制采用了電器(qi)時(shi)間(jian)控制，分(fen)為(wei)手動(dong)和(he)自(zi)(zi)動(dong)兩種，用戶可(ke)以根據實(shi)際(ji)含砂(sha)量將(jiang)提砂(sha)時(shi)間(jian)靈活調整，自(zi)(zi)動(dong)時(shi)停止時(shi)間(jian)是99分(fen)鐘。進氣提砂(sha)時(shi)間(jian)和(he)相應(ying)配套砂(sha)水(shui)分(fen)離機(ji)(ji)的開機(ji)(ji)時(shi)間(jian)也(ye)由用戶根據實(shi)際(ji)情況靈活調整，一般為(wei)風機(ji)(ji)每提砂(sha)一次15-30分(fen)鐘，砂(sha)水(shui)分(fen)離機(ji)(ji)工作時(shi)間(jian)相應(ying)加(jia)長一點即可(ke)。
