Working principal
The liquid/solid mixed fluid is evenly distributed in the Vertical scraper centrifuges drum through the feed pipe and the distribution plate. Under the action of the centrifugal field, the solid phase is intercepted by the filter disc and the liquid phase is filtered out. Feeding continues until the material is full, and then the feeding is stopped. If the process requires, the filter cake is washed and purified, and the washing liquid is filtered out at the same time. Further deliquescence is performed until the separation requirements are met. Reduce to low speed, the scraper scrapes off most of the filter cake, and the bag device unloads the remaining filter cake, completing a working cycle.
The LGZ and PGZ series have the same process as above except that they do not have the bag stretching function.
Control Flow
The operation of the centrifuge is controlled by PLC, and the system runs automatically according to the preset operating program. Different models have corresponding operating parameters or adjustment ranges. Appropriate operating parameters are set for specific working conditions during commissioning and subsequent operation to meet separation requirements. The control system automatically repairs or protects overloads during actual operation.
The automatic control system controls the centrifuge host, hydraulic system, pneumatic system, nitrogen protection system, valves, and pumps, valves, material conveying systems, etc. related to the centrifuge.
