離心式污(wu)(wu)泥(ni)脫水(shui)(shui)(shui)機(ji)，在污(wu)(wu)水(shui)(shui)(shui)處理(li)(li)廠的污(wu)(wu)泥(ni)脫水(shui)(shui)(shui)處理(li)(li)中(zhong)得到了廣泛的應(ying)用(yong)。雖然不(bu)同(tong)(tong)生產廠家(jia)的不(bu)同(tong)(tong)規格或型號的離心式污(wu)(wu)泥(ni)脫水(shui)(shui)(shui)機(ji)具(ju)有不(bu)同(tong)(tong)的設備(bei)結(jie)構、設備(bei)材質、規格和運行調(diao)整機(ji)構等(deng)，但是(shi)其(qi)基本設備(bei)原理(li)(li)是(shi)相(xiang)似的，現對其(qi)進行簡單的介紹(shao)，以(yi)便于現場用(yong)戶更好的使用(yong)和調(diao)整。

離(li)心式(shi)污泥脫水機主要(yao)由轉鼓、螺旋、差(cha)速系統(tong)(tong)、液位擋板、驅(qu)動系統(tong)(tong)及控制系統(tong)(tong)等組成。

工作(zuo)原理

分(fen)(fen)離(li)的目的是(shi)使(shi)混(hun)合液(ye)(ye)(ye)(ye)中(zhong)(zhong)的固(gu)體(ti)(ti)(ti)(ti)從液(ye)(ye)(ye)(ye)體(ti)(ti)(ti)(ti)中(zhong)(zhong)分(fen)(fen)離(li)出(chu)來，或者是(shi)把二(er)(er)種互不相(xiang)溶且重(zhong)(zhong)(zhong)(zhong)不同的混(hun)合液(ye)(ye)(ye)(ye)分(fen)(fen)離(li)開。在(zai)裝有輕、重(zhong)(zhong)(zhong)(zhong)兩種液(ye)(ye)(ye)(ye)體(ti)(ti)(ti)(ti)以及固(gu)相(xiang)顆粒的混(hun)合液(ye)(ye)(ye)(ye)的容器中(zhong)(zhong)，由于(yu)(yu)重(zhong)(zhong)(zhong)(zhong)力(li)作(zuo)(zuo)用，靜置(zhi)一段時間后(hou)，會出(chu)現(xian)分(fen)(fen)層現(xian)象，比(bi)(bi)重(zhong)(zhong)(zhong)(zhong)zui大(da)的固(gu)體(ti)(ti)(ti)(ti)顆粒會下(xia)沉到容器zui底部(bu)，zui上面為輕相(xiang)液(ye)(ye)(ye)(ye)體(ti)(ti)(ti)(ti)，在(zai)二(er)(er)者之間是(shi)重(zhong)(zhong)(zhong)(zhong)相(xiang)液(ye)(ye)(ye)(ye)體(ti)(ti)(ti)(ti)。當混(hun)合液(ye)(ye)(ye)(ye)體(ti)(ti)(ti)(ti)進(jin)(jin)入離(li)心機轉(zhuan)(zhuan)鼓(gu)并(bing)隨轉(zhuan)(zhuan)鼓(gu)高速旋轉(zhuan)(zhuan)起來后(hou)，這個分(fen)(fen)層過(guo)程(cheng)(cheng)由于(yu)(yu)離(li)心力(li)場的作(zuo)(zuo)用會比(bi)(bi)重(zhong)(zhong)(zhong)(zhong)力(li)作(zuo)(zuo)用下(xia)的過(guo)程(cheng)(cheng)大(da)幾千倍(bei)的速度加快進(jin)(jin)行（分(fen)(fen)離(li)因數就是(shi)重(zhong)(zhong)(zhong)(zhong)力(li)加速度的倍(bei)數）。混(hun)合液(ye)(ye)(ye)(ye)中(zhong)(zhong)的固(gu)體(ti)(ti)(ti)(ti)顆粒比(bi)(bi)重(zhong)(zhong)(zhong)(zhong)較大(da)，受到的離(li)心力(li)也大(da)，迅速沉降到轉(zhuan)(zhuan)鼓(gu)內壁，而液(ye)(ye)(ye)(ye)體(ti)(ti)(ti)(ti)則被擠向轉(zhuan)(zhuan)鼓(gu)中(zhong)(zhong)心，液(ye)(ye)(ye)(ye)體(ti)(ti)(ti)(ti)若是(shi)有輕、重(zhong)(zhong)(zhong)(zhong)二(er)(er)相(xiang)，則重(zhong)(zhong)(zhong)(zhong)相(xiang)靠(kao)近轉(zhuan)(zhuan)鼓(gu)壁，輕相(xiang)靠(kao)近轉(zhuan)(zhuan)鼓(gu)中(zhong)(zhong)心，在(zai)二(er)(er)相(xiang)分(fen)(fen)離(li)機中(zhong)(zhong)設(she)置(zhi)了(le)液(ye)(ye)(ye)(ye)相(xiang)溢流(liu)口和(he)固(gu)餅出(chu)口，在(zai)三相(xiang)分(fen)(fen)離(li)中(zhong)(zhong)，設(she)置(zhi)了(le)輕相(xiang)液(ye)(ye)(ye)(ye)體(ti)(ti)(ti)(ti)和(he)重(zhong)(zhong)(zhong)(zhong)相(xiang)液(ye)(ye)(ye)(ye)體(ti)(ti)(ti)(ti)排出(chu)口和(he)固(gu)餅出(chu)口，并(bing)設(she)置(zhi)了(le)進(jin)(jin)料口、螺旋推(tui)料器，使(shi)整個分(fen)(fen)離(li)過(guo)程(cheng)(cheng)連續進(jin)(jin)行。
