FeedProtect
Plnící zóna s vyměnitelnou ochranou proti opotřebení
Unikátně navržená plnící zóna FeedProtect zajišťuje mírné zrychlení produktu a minimální turbulence, což vede k nízké abrazi a spotřebě energie. Konstrukce FeedProtect je vybavena vyměnitelnými vložkami s ochranou proti opotřebení, které zajišťují vysokou provozní životnost vašeho zařízení.
DeepPond
Vysoký separační výkon a energetická úspornost
Zvětšením hloubky kapaliny uvnitř bubnu se vytvoří větší objem, což vede k prodloužení doby zdržení a zlepšení separačního výkonu. Konstrukce SuperPond vyniká hlubším jezírkem a menším průměrem odtoku pevných látek, což vede k vysoké suchosti pevných látek, čistému centrátu při vysokých průtocích a také k nízké spotřebě energie.
PowerTubes
Odtok kapaliny s regulací její hloubky a rekuperací energie
Nastavitelné vývody PowerTubes jsou navrženy tak, aby vypouštěly kapalinu tangenciálně ke směru otáčení, čímž podporují rotaci bubnu, získávají zpět energii a minimalizují její spotřebu.
FlightProtect
Protection against wear on conveyor spirals
FlightProtect is a wear-resistant coating specifically designed for conveyor flights that preserves the integrity of each flight and extends its service life.
LiquidLock
Floating solids accelerator
A special device that accelerates floating solids from the surface into the solids layer. This results in liquids leaving the decanter centrifuge being of better quality.
How does a sludge dewatering centrifuge work?
Separation takes place in a horizontal cylindrical bowl equipped with a screw conveyor. The feed enters the bowl through a stationary inlet tube and is accelerated smoothly by an inlet distributor. The centrifugal force that results from the rotation then causes sedimentation of the solids on the wall of the bowl.
The conveyor rotates in the same direction as the bowl, but slightly slower, thus moving the solids towards the conical end of the bowl. A special patented Liquid-Lock conveyor design accelerates light particles before discharge for optimum separation. This also contributes to the small footprint of the unit.
Separation takes place throughout the entire length of the cylindrical part of the bowl. Relatively low G-force is needed for the i-Dec decanter to deliver good performance in terms of capacity and cake dryness. This contributes to low power consumption.
The clarified liquid leaves the bowl by flowing out of the casing viaspecial patented energy-saving PowerTubes that enable the effluent to discharge at lower speeds. The cake leaves the bowl into the casing through the solids discharge openings.
