Product Description

Product Description

Labyrinth seal is used for both bowl ends of LW standard type decanter centrifuge, simple and convenient, after separation, the solid phase is conveyed to the solid discharge port by scroll conveyor, and discharged out of centrifuge under centrifugal force caused by high speed rotation; while the liquid phase drains out under gravity and centrifugal force through the overflow plate. This series decanter centrifuge features easily operation, continuous and stable running, and wide application scope.

Separation takes place in a horizontal bowl equipped with a scroll conveyor. The process material is fed into the bowl through a stationary inlet tube and is smoothly accelerated in the accelerate chamber. Centrifugal forces cause instant sedimentation of the solids on the wall of the bowl. The conveyor rotates in the same direction as the bowl, but at a different speed, thus moving the solids towards the conical end of the bowl.

 

LW series decanter centrifuge is a horizontal centrifuge with continuous feeding and continuous discharging. It has two-phase (solid-liquid) separation and three-phase (solid-liquid-liquid) separation.

Working principle

The hydraulic conveyor gearbox is connected with the bowl of the decanter centrifuge, both of them rotates in high speed. The spline shaft on the gearbox rotor is connected with the conveyor, and rotates in different speed driven by the high pressure oil, that's we call the differential speed. The conveyor gearbox is connected with the hydraulic pump by flexible hose, so there is no need of gearbox between the bowl and conveyor. Conveyor torque gives pressure to the hydraulic system. With the action of such pressure, the different speed can by adjusted by adjusting the oil supply and flow rate.

The hydraulic conveyor driving is a closed driving system, including the centrifuge bowl and conveyor. It is independent from the bowl driving. The hydraulic conveyor driving is different from other mechanical conveyor driving system which relies on bowl rotating to generate differential speed. The hydraulic driving device is directly mounted on the conveyor assembly, and is driven by hydraulic pump aggregate. Therefore it is independent from the bowl driving system.

 

Features

Vertical base design and symmetrical arrangement of motor and bowl assembly, that ensures stable operation and less vibration.
Main parts such as the bowl and conveyor are made of corrosion-resistant stainless steel or duplex steel, offering high maximum bowl speed and high centrifugal force.
Dual motor drive makes bowl speed and conveyor speed adjustable.
Screw conveyor flights tiled or lined with ceramic, tungsten carbide, or other hard alloys.
Optionla planetary gearbox and hydraulic gearbox, offering wide range of differential speed adjustment.
Multiple safety protection: bowl speed and differential speed detection, over-vibration protection, motor overload and overheat protection, bearing temperature monitoring, conveyor torque protection and gas-tight explosion-proof protection.
