LGZ平板刮刀卸料离心机

工作原理

         液/固混合流体通过进料管经布料盘加速均匀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，同时将洗涤液滤出。进一步脱液，直至达到分离要求。降至低速，刮刀将大部分滤饼刮下，抻袋装置将残余滤饼卸出，完成一次工作循环。

         LGZ系列除了没有抻袋功能，其它过程与上述同样。

Operating principle

The mixture of solid and liquid is distributed uniformly&quickly in centrifuge drum by feeding tube and distributing evenly through the distributing disk. acting on the centrifugal position. Liquid-solid mixed fluid intercept the solid phase through the fitter to filter out the liquid phase. Centrifuge continues to feed until full. Then stop. Solid cake is rinsed and purified when the process requires. And the rinsing liquid is filtered out meanwhile.  Centrifuge further filter until the separation requirements are met.

控制过程

         离心机运行由PLC控制，系统按预设运行程序自动运行。不同的机型有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，以满足分离要求。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。

Control Process

The operation of centrifuge is controlled by PLC. The system runs automatically according to the preset program. Different centrifuges have corresponding operating parameters or range of adjustment.

In order to meet the requirements of separation. appropriate operation parameters are set for specific conditions

in debugging and subsequent operation. The control system can automatically repair or protect the overload in the actual operation.

Automatic control system controls centrifuge mainframe, hydraulic system, pneumatic system, N2 protection system,ａnd pump, valve, material conveying system related with centrifuge, etc.
