◎工作原理

         

Working principle

        待分离物料由进料管进入高速旋转的离心机转鼓,在离心力场的作用下,均布在转鼓内壁的滤布上,进行过滤分离。分离过程中液相透过固相物料、滤布的缝隙和转鼓壁上的小孔,从底盘的出液管流出;而固相物料则被截留在转鼓壁内。达到分离要求后,通过刮刀卸料,出渣口排出。最后,滤袋清洁机构动作,清除残余的固相物料   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、主轴轴承运行安全
1)优化主轴承结构布局,装配与拆卸简单可靠,保证轴承正常使用。
2)集中式油脂润滑。主轴承上下组单独高压供油,降低现场维护保养的难度,为设备安全运行提供保障条件。
二、料液在转鼓内均布安全
布料方式:叶片风轮式旋转斜盘布料。
1) 改善因料液进入布料器内形成的流体紊乱而造成布料器抛料现象。
2) 消除因布料器工作时,在出料口形成流体压力墙造成的布料受阻及分布不均现象。
3)减少料液在布料器内停留时间,快速通过,均匀布料。
4)改善因布料不均而造成的设备异常震动现象,降低对设备零部件的损害。
三、物料安全
物料清除方式:杠杆式自动清除滤袋上残留物料。滤袋在工作状态时贴附于转鼓内壁,在完成料液分离、刮刀卸料之后,滤袋在连杆系统的作用下发生形变(成为上大下小与主轴同心的60度圆锥),从而将滤布壁上的残留固相物剥离,从下卸料口排出。
1)连杆结构简单,功能可靠。
2)提高分离效果。
3)有效清除残留物料,避免物料交叉污染。
四、操作安全
设计时充分考虑设备的操作安全性,保证现场操作人员及设备运行安全。
1)外置手动润滑油脂加油泵,方便现场人员操作,确保主轴轴承当班正常保养维护,有效降低设备故障率,提高生产效率。
2)设备上的高压油管路、线路设计在保护壳内,并将接口集中放置,现场整洁无外露,确保人、机安全。
3)HMI人机界面,PLC控制,整机自动化操作,无人看护,自动监测与保护。
 

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.
