GK horizontal peeler centrifuges
Principle of Operation
When operating, the feed valve is opened, and the slurry is applied evenly to the filter medium installed in the perforated basket via a feeding pipe with deflector. The liquid phase in the slurry is centrifuged from the cake at high speed through the filter medium and the small bores of the basket during which the solids form on the filter medium in the shape of filter cake. When the filter cake layer reaches the predetermined thickness, feeding is stopped. After the intermediate centrifugation, wash liquid is applied evenly to the product cake via the wash pipe, and the cake is washed. After washing, the washing water valve is closed. The cake continues to be spun until the required residual cake moisture is achieved. The filter cake is then scraped out through a chute by the scraper knife that swings into the filter cake. The scraper knife is returned after filter cake is discharged from the centrifuge. Then, the machine runs for the subsequent operating cycle.
Design of products
GK horizontal peeler centrifuges are mainly composed of the rotating components that include the perforated basket and its shaft, driving system, the inertia block system (NL configuration), hydraulic system, pneumatic system, and electrical control system. The peeled filter cake can be discharged from the centrifuge through an inclined chute or a horizontal screw conveyor, etc.
Special design features
The centrifuge adopts the variable frequency drive (VRD) and the PLC control, equipped with automation system, hydraulic system, and pneumatic system. The entire process of feeding, filtration, washing, dry spinning, and cake discharging is automatically controlled. It is convenient to use and easy to operate and can complete the individual process steps at full rotational speed to meet the requirements of the high hourly production. The centrifuge adopts a fully enclosed design and optional instrumentation integrated into the control system including the automatic nitrogen filling system and oxygen monitoring system to meet the requirements of solid-liquid separation of toxic, harmful, easily oxidizable, flammable, explosive and other materials. It is equipped with comprehensive monitoring and protecting devices that include front door locking, machine vibration, bearing temperature, lubrication oil flowrate, cake level, scraper position, and motor overload protecting, etc., According to different cake solids, the discharge chute or screw conveyor can be selected to adapt to a variety of slurries.
