二、砂水分離器結(jié)構(gòu)工作原理

砂水分離機(jī)由無軸螺旋、襯條、U形槽、水箱,導(dǎo)流板和驅(qū)動裝置等組成。當(dāng)砂水混合液從分離器的一端項(xiàng)部輸入水箱,混合液中較大的如砂粒等將沉積于U形槽底部,在螺旋的推坳下,砂粒沿斜置的U形槽底提升,離開液面后繼續(xù)推移一段距離,在砂粒充分脫水后經(jīng)排砂口卸置砂桶,而與砂分離后的水則從溢流口排出并送往廠內(nèi)進(jìn)水池。

三、砂水分離器特點(diǎn)

1、砂水分離機(jī)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(diǎn)。

2、砂水分離器分離效率可達(dá)96%98%,可分離出粒徑0.2nn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,砂水分離機(jī)與泵式沉砂器和儲砂間的砂泵的性能相配。在必要的時(shí)候,也可以連續(xù)運(yùn)行。

4、砂水分離機(jī)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(jì)為保證物料流通,無堵塞,無軸螺旋體具有足夠的強(qiáng)度和鋼度,保證在工作荷載上限下,不會產(chǎn)生影響使之變形或拉長。

5、無軸螺旋的支承軸承防水、防塵、耐磨、自動潤滑。

6、砂水分離機(jī)的分離池采用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(jìn)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。所有管件和法蘭盤采用不銹鋼。

7、砂水分離機(jī)進(jìn)出管品徑設(shè)計(jì)能防止水中雜物的堵塞。

8、砂水分享機(jī)及輸助件的配置適合連續(xù)工作和間歇工作的要求。

9U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(yùn)轉(zhuǎn)零件,因此螺桿磨損低,幾乎不粉墨登場維修。

11、驅(qū)動裝置采用軸裝式減速機(jī),輸出軸與螺旋器直聯(lián)。

砂水分離器

五、主要機(jī)構(gòu)及工作原理

砂水分離器由驅(qū)動裝置、螺旋體、水箱、U形槽、襯條等部件組成。砂水分離機(jī)本體由砂水分離槽和螺旋輸砂槽組成。水槽的分離流量上限和螺旋輸砂能力分離槽內(nèi)停留時(shí)間>2min,并具有足夠的余量。

1、主要結(jié)構(gòu)

⑴驅(qū)動裝置裝采用軸裝式減速機(jī)與螺旋軸直聯(lián)。在輸砂槽頂部裝有支承軸承,螺旋軸軸承有可靠的密封和良好的潤滑條件,該軸承裝置能防水、防塵,并便于潤滑和維修。

螺旋體的驅(qū)動裝置采用國際知名品牌的齒輪減速電機(jī),服務(wù)系數(shù)不小于1.6。

齒輪為合金鋼,滲碳處理,齒面硬度不低于HRC58~62。電機(jī)應(yīng)適用于戶外使用,防護(hù)等級IP65,電壓等級為三相、380v、50Hz,F(xiàn)

級絕緣,電機(jī)的額定功率應(yīng)高于實(shí)耗功率上限10%以上。

⑵螺旋軸螺旋直徑為Φ280mm,采用無軸螺旋,能保證物料輸送流暢無堵塞。

⑶螺旋輸砂槽為U型斷面,螺旋槽直徑為320mm,安裝角度約25°,除進(jìn)料口敞開外,其余部分均為加平蓋密封結(jié)構(gòu),為可拆方式,上端設(shè)出料口,高出地面約1.75m。

螺旋輸送槽出料口高于分離器槽頂300mm以上。

⑷螺旋輸砂槽與水箱為整體結(jié)構(gòu),有足夠的強(qiáng)度和剛度,無滲漏。整體結(jié)構(gòu)由型鋼支撐固定在混凝土基礎(chǔ)上。

2、工作原理

來自沉砂池的砂水混合物進(jìn)入砂水分離槽中,進(jìn)行砂水分離,水溢出池外,砂沉到槽底。轉(zhuǎn)動的螺旋軸將砂沿25°螺旋槽輸送到頂部出料口,砂在輸送過程中進(jìn)一步分離,從而保證出料口的砂含水率不大于60%。

六、主要零件材料

槽本體(包括密封蓋)材料為不銹鋼304。

螺旋體材料為耐磨耐蝕特種鋼。

螺栓等緊固件材料為不銹鋼316。

電機(jī)減速機(jī)
