如何進行水處理

衡美水處理為您介紹一種經(jīng)久耐用、性能優(yōu)越的水處理設(shè)備——砂水分離器,并向您詳細介紹操作維護說明

一、設(shè)備定義

砂水分離器是一種用于分離混合物中的砂和水的設(shè)備,廣泛應用水處理領(lǐng)域、建筑工地、采砂場等場所。通過砂水分離器可以有效將水中的砂、土壤顆粒等固體顆粒物質(zhì)與水分離,提高水質(zhì)純度,保護環(huán)境,同時也有助于回收利用水資源。

砂水分離器

二、工作原理

砂水分離器主要由無軸螺旋、襯條、U型槽、水箱、導流板、出水堰驅(qū)動裝置配件組成。

砂水混合液從分離器一端頂部輸入水箱,混合液中重度較大的如砂粒等將沉積于槽形底部,在螺旋的推動下,砂粒沿斜置的U型槽底提升,離開液面后繼續(xù)推移一段距離,在砂粒充分脫水后經(jīng)排砂口卸至盛砂桶。而與砂分離后的水則從溢流口排出并送往廠內(nèi)進水池。

砂水分離器設(shè)備一般安裝傾角在20-30度之間,砂水混合液從進水管進入設(shè)備,混合液通過分離機上部的聚集器,在水流的作用下,使混合液中的砂粒與有機物進行分離,砂、水進入集砂槽中,比重較大的顆粒(如砂粒)由于自重而下降沉積于螺旋槽底部,在螺旋葉片的推動下,物料沿斜置的U型槽底部提升,離開液面后,繼續(xù)上移一段距離,砂粒中的水分逐漸在螺旋槽中的間隙中流回水槽,砂粒也逐漸干化到出料口處,依靠自重落入其它輸送裝置。上清液則不斷的從排水堰溢出管道流出,有機物在水流旋渦的作用下,則從聚集器的上頂流出,通過管道回流至污水井中,從而達到砂水分離的目的。

三、設(shè)備特點

1、砂水分離器的沉淀裝置和輸砂裝置為封閉式一體化結(jié)構(gòu),并具有結(jié)構(gòu)緊湊、重量輕、高工作可靠性、維修工作量少等特點。

2、砂水分離器分離效率可達96%~98%,可分離出粒徑≥0.2mm的顆粒,回收率不低于98%;直徑大于0.1mm的砂礫去除率不小于80%。

3、在正常情況下,砂水分離器與泵式沉砂器和儲砂間砂泵的性能相配。在必要的時候,也可連續(xù)運行。

4、砂水分離器的殼體、支架、輸砂器等重要部件的材質(zhì)采用不銹鋼制作,U型槽內(nèi)的輸送螺旋形式為無軸螺旋,其結(jié)構(gòu)設(shè)計為保證物料流通,無堵塞無軸螺旋體具有足夠的強度和剛度,保證在工作荷載上限下,不會產(chǎn)生影響使之變形或伸長。

5、無軸螺旋的軸承能夠防水、防塵、耐磨、自動潤滑。

6、砂水分離機所有管件和法蘭盤采用不銹鋼材質(zhì)。分離池采用304不銹鋼加工焊接而成,底部為半圓形,用于支撐螺旋輸送器。進水口和溢流管安裝在容器的上部,排水管安裝在下部便于維修。

7、砂水分離機進出管口徑設(shè)計能防止水中雜物的堵塞。

8、砂水分離機及輔助件的配置適合連續(xù)工作和間歇工作的要求。

9、U型螺旋槽內(nèi)裝有足夠數(shù)量的可換襯體,結(jié)構(gòu)簡單,使用壽命長,便于更換

10、設(shè)備中沒有高速運轉(zhuǎn)零件,因此螺桿磨損低,幾乎不需維修。

11、驅(qū)動裝置采用軸裝式減速機,輸出軸與螺旋器直聯(lián)驅(qū)動電機的防護等級為IP55,絕緣等級為F級。

四、安裝、調(diào)試

1、砂水分離器出廠時已根據(jù)用戶的設(shè)備安裝角度或出料高度配備好落地支架,安裝時用膨脹螺栓固定。

2、砂水分離器的安裝角度誤差為±1度。

3、設(shè)備吊運時不允許碰撞和滑落,并采取有效措施保護設(shè)備的不銹鋼表面,不允許有劃傷磨損及凹坑等。

4、開機前檢查減速機油位是否正常,使用300小時后更換一次潤滑油,連續(xù)運行超過16小時的設(shè)備,以后每2500小時更換一次,每天運行8小時的設(shè)備可延長至4000小時。

5、通電試機時應先點動,確認無部件磨擦后,才能進入正常試運轉(zhuǎn)。

五、運行前準備

1、設(shè)備管理人員和操作人員須詳細了解設(shè)備的構(gòu)成和性能,

仔細閱讀各設(shè)備的有關(guān)資料。

2、檢查砂水分離器溢流口閥門是否打開。

3、檢查分離器箱體內(nèi)是否有卡滯螺旋的雜物,如有應及時清理。

4、冬季運行時,應經(jīng)常檢查箱體內(nèi)是否有結(jié)冰,必要時進行清除,以免螺旋軸過扭損壞。

5、檢查減速箱的潤滑油是否符合要求,如有滲漏或耗損,隨時補油至油位。

6、查看值班記錄、現(xiàn)場,檢查是否有故障記錄或顯示。

7、如果砂水分離器工作中有超過24小時間歇,重新開始工作時須有操作員在場觀察。

六、設(shè)備啟動

1、手動模式

1)將控制柜上的模式選擇按鈕置于“手動”位置。

2)按下啟動按鈕,設(shè)備開始運轉(zhuǎn),檢查設(shè)備有無抖動及卡滯現(xiàn)象。

3)停時,待分離器箱體內(nèi)砂子排凈后關(guān)閉設(shè)備。

2、自動控制模式

1)將模式選擇按鈕置于“自動”位置。

2)設(shè)備將按照規(guī)定的程序自動投入運行。

3)設(shè)定的時間控制程序應與提砂泵、電動閥的時間程序相對應。


砂水分離器


七、使用和維護保養(yǎng)

1、操作人員應進行培訓合格后上崗操作。

2、砂水分離器按巡檢維護修理潤滑管理等制度要求進行。

3、每天巡檢機器運轉(zhuǎn)情況,不存在不正常噪音,密封有無泄漏,并適當加注軸承潤滑脂。每月檢查驅(qū)動裝置齒輪箱中的油位,并加高到所需高度。

4、每兩年進行一次設(shè)備解體大修、拆開清洗減速機,更換磨損的另件,更換密封圈及磨損的襯套,檢查及校正螺旋體等。

5、砂水分離器因故障原因停機應查明原因,排除故障后才能重新開機。

6、停機三天以上時,應沖洗或排除設(shè)備內(nèi)部物料,以免結(jié)塊。

7、在冬季氣溫偏低時,應注意防凍,出現(xiàn)結(jié)塊和結(jié)冰時,應除后開機。

若與其它設(shè)備配套使用時,控制按鈕集中在一個控制箱中。
