工作原理

    液/固混合流体通过进料管分布于离心机转鼓内,在离心力场作用下,通过滤片截留固相,滤出液相。持续进料,直至料满,停止进料,如工艺需要时则对滤饼进行洗涤、提纯,同时将洗涤液渝出。进一步脱液,直至达到分离要求。在全速或中速时,刮刀将大部分滤饼刮下,完成一次工作循环。

    GKH采用虹吸原理,增加过滤动力,实现更低的滤饼含湿率。

 

Operating principle

The solid and liquid mixture will be fed into the centrifuge drum via feed pipe and distributed evenly all over the inner wall of the drum, at where the solid phase will be retained by filter disk under effect of centrifuge field while liquid phase discharged out of the filtration process. The feeding process will keep going on until the centrifuge drum is fully charged. Filtering cake will be rinsed and purified as necessary and rinsing water will be discharged meanwhile. Then, there comes a further dehydration process till effective separation is achieved. In process of full or moderate speed running, the scrapper will peel off most of the filtering cake and one entire working cycle completed.

GKH' s operation is based on siphon principle, designed with filtering power, resulting in lower water content of filtering cake.

 

控制流程

Control process

 

         离心机运行由PLC控制,系统按预设程序自动运行。不同的机型系统有着相应的运行参数或调整范围,对特定的工况在调试和后续的运行中设定合适的运行参数,满足分离要求。控制系统对实际运行过程中的过载进行自动修复或保护。

         自动控制系统对离心机主机、液压系统、气动系统、氮气保护系统、阀门以及与离心机相关的泵、阀、物料输送系统等进行控制。

 

Centrifuge operation is PLC controlled, where the system will run preset program automatically with operation parameters or their adjustment range varying for different models/types of unit. Appropriate operation parameters will be defined and set for specific working condition based on results of testing/commissioning and subsequent operation in the aim to achieve effective separation.

The control system will fix or protect from overload in process of operation automatically.

The automatic control system controls main engine, hydraulic system, pneumatic system, N2 protection system, valves as well as pumps, valves and material conveyance system etc. relating to the centrifuge.
