◎工作原理

         

Working principle

        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

         

Safe in use

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. Main shaft bearing safety running
1) Optimize main shaft bearing structure,assembly and dis-assembly both simply and reliable,ensure safe usage of bearing.
2) Centralized lubrication of grease. Main bearing separately supply grease to upper unit and lower unit by high pressure,downgrade of on site maintenance difficulty.
B. Liquid material safely spread within drum
Distribution method:Blade wind wheel rotative distribution
1) Relieve attrition caused by liquid disorder.
2) Remove distribution blockage and unevenly distribution made by liquid pressure wall nearby outlet.
3) Reduce the time of material stays within distributor,evenly distribution.
4) Relieve unusual vibration of equipment,protect accessories and components.
C. Residues safety
Residues removal:lever type automatically remove residues on filter bag.
In operate state,filter bag adhesive to drum interior wall;in non-operate state,filter bag deforms under the effect of connecting rod(become a 60 degree circular cone concentric with main shaft),remove residues on filter cloth and discharge by outlet.
1) Connecting rod has a simple structure and reliable function.
2) Improved separation effectiveness.
3) Effectively remove residues,protect material from cross infection.
D. Operation safety
Unique design ensure safety of on site personnel and equipment running.
1) External manual oil pump,facilitate on site personnel to operation,ensure on-duty maintenance for main shaft bearing ,reduce failure rate meanwhile promote production efficiency.
2) High pressure oil pipeline and circuit designed within shield,interfaces are laid together. Clean and tidy,ensure safety of human and equipment.
3) Adopt HMI and PLC,unattended operation,automatically monitoring and protecting.
