The decanter centrifuge is for continuous separation of 3-phases systems consisting of two immiscible liquids and solids.
The decanter centrifuge is for continuous separation of 3-phases systems consisting two immiscible liquids and solids. Stock liquid is brought into the bowl through a centripetal pump. Solid matter settles into outer larger by the centrifugal force. The settled sediment is pushed into the drying area at the cone of the bowl by rotary difference between spiral and bow land discharged from the outlet. Because of the different gravity of emulsion of liquid phases in the bowl, the light liquid and the heavy liquid are separated by the baffle at the cylinder end of the bowl, light liquid flows out from the light liquid outlet through the centripetal pump and heavy liquid flows out from the heavy liquid outlet. The drum and scroll conveyor are made of stainless steel and titanium resisting corrosion. The scroll conveyor was coated with wearable alloy or welded with alloy plate. Stepless speed regulation for the bowl. Step or stepless speed regulation for scroll's differential speed. Simple lubrication. Safety protection: Rotation rate detection over, vibration protection, motor overload and overheat protection, protection for scroll when zero differential speed occurs.
For the highly sticky materials, it can add the hydraulic differential gear to stabilize. The centrifuge is a specially developed continuous Solid-Bowl horizontal Scroll Discharge centrifuge for effective separation of slurries into liquid-solid phases/liquid-liquid-solid phases, with the application of centrifugal sedimentation principle. A decanter centrifuge separates solids from one or two liquid phases in one single continuous process. This is done using centrifugal forces that can be well beyond 3000 times greater than gravity. When subject to such forces, the denser solid particles are pressed outwards against the rotating bowl wall, while the less dense liquid phaseforms a concentric inner layer. Different dam plates are used to vary the depth of the liquid the so-called pond as required. The sediment formed by the solid particles is continuously removed by the screw conveyor, which rotates at a different speed than the bowl. As a result, the solids are gradually "ploughed" out of the pond and up the conical "beach". The centrifugal force compacts the solids and expels the surplus liquid. The dried solids then discharge from the bowl. The clarified liquid phase or phases overflow the dam plates situated at the opposite end of the bowl. Baffles within the centrifuge casing direct the separated phases into the correct flow path and prevent any risk of coss-contamination.
The speed of the screw conveyor may be automatically adjusted by use of the variable
Frequency drive in order to adjust to variation in the solids load.
