全自動下卸料自清潔型離心機 | PGZQ series | |
PGZQ全自動下卸料自清潔型離心機是一種立式、小刮刀卸料、自動間歇操作過濾式離心機。它在一個工作周期內可按照不同要求,依次自動完成進料、分離、卸料、清潔濾袋等工序。該機采用HMI人機界面觸摸操作系統和PLC可編程控制器,配合變頻器控制轉速系統、機械式自動卸料裝置、料滿自動檢測裝置及各類閥門聯合動作,實現整機的自動化操作。適用于細顆粒和中等顆粒度固相懸浮液的固液分離,也可用于纖維狀物料的固液分離,主要服務于化工、食品、制藥、礦物、環保等行業。 | PGZQ Automatic self-cleaning bottom discharge centrifuge,discharges by small scraper,operates intermittently.It automatically completes feeding,separating,discharging and cleaning with in work cycle according to different requirements.PGZQ series centrifuge adopts HMI and PLC,working accompanies with converter,machinery automatic discharging unit,overload automatic detection unit and valves,to realizes automatic operation of whole machine set.It is suit for separation of solid suspension includes tiny and medium particles,also suit for separation of fibrous material.Application field:chemical industry,food industry,pharmaceutical industry,mining industry and environmental protection industry,etc. |
◎工作原理 | | |
待分離物料由進料管進入高速旋轉的離心機轉鼓,在離心力場的作用下,均布在轉鼓內壁的濾布上,進行過濾分離。分離過程中液相透過固相物料、濾布的縫隙和轉鼓壁上的小孔,從底盤的出液管流出;而固相物料則被截留在轉鼓壁內。達到分離要求后,通過刮刀卸料,出渣口排出。最后,濾袋清潔機構動作,清除殘余的固相物料。 | Material comes into rotating drum trough feed tube,centrifugal force field makes it spread evenly on filter cloth of interior wall.During separation process,liquid trough gap within solid phase and filter cloth also holes of drum interior wall,discharges by outlet.While solid material retained within drum wall.After separation,scraper cuts filter cake into pieces,then discharges by outlet.The last step is self-cleaning,remove solid residues. |

◎使用安全 | | |
一、主軸軸承運行安全 1)優化主軸承結構布局,裝配與拆卸簡單可靠,保證軸承正常使用。 2)集中式油脂潤滑。主軸承上下組單獨高壓供油,降低現場維護保養的難度,為設備安全運行提供保障條件。 二、料液在轉鼓內均布安全 布料方式:葉片風輪式旋轉斜盤布料。 1) 改善因料液進入布料器內形成的流體紊亂而造成布料器拋料現象。 2) 消除因布料器工作時,在出料口形成流體壓力墻造成的布料受阻及分布不均現象。 3)減少料液在布料器內停留時間,快速通過,均勻布料。 4)改善因布料不均而造成的設備異常震動現象,降低對設備零部件的損害。 三、物料安全 物料清除方式:杠桿式自動清除濾袋上殘留物料。濾袋在工作狀態時貼附于轉鼓內壁,在完成料液分離、刮刀卸料之后,濾袋在連桿系統的作用下發生形變(成為上大下小與主軸同心的60度圓錐),從而將濾布壁上的殘留固相物剝離,從下卸料口排出。 1)連桿結構簡單,功能可靠。 2)提高分離效果。 3)有效清除殘留物料,避免物料交叉污染。 四、操作安全 設計時充分考慮設備的操作安全性,保證現場操作人員及設備運行安全。 1)外置手動潤滑油脂加油泵,方便現場人員操作,確保主軸軸承當班正常保養維護,有效降低設備故障率,提高生產效率。 2)設備上的高壓油管路、線路設計在保護殼內,并將接口集中放置,現場整潔無外露,確保人、機安全。 3)HMI人機界面,PLC控制,整機自動化操作,無人看護,自動監測與保護。 | A.
