➤➤➤ Design and function
The HUBER TrashMax® Screen is ideal to be used in pumping stations, as first treatment stage of wastewater treatment plants or industrial plants, and in the inlet to power plants. The screen removes coarse and bulky material and therefore protects downstream systems.
The cleaning elements, attached to the chain system, can easily be adjusted to different requirements and remove even heavy objects and bulky material. As the cleaning rakes can be variably adapted, removal capacity is then adjustable. The benefit of high cleaning efficiency is especially favourable for high solids loads.
The installation height of the TrashMax® above ground level is very small and only dependent, even in case of deep channels, on the installation height of screenings transport or disposal units. Both ends of the cleaning rakes are connected to robust drive chains. Two wear-resistant rollers on each side, running in lateral guiding tracks, ensure true and smooth running of the rakes as they move upwards with the result of reliable intensive screen rack cleaning. Each chain is driven by a sprocket on a common shaft and a gear motor.
The rakes of the TrashMax® Screen mesh with the screen rack bars at the bottom dead centre, at first with the back cleaned screen rack and then with the behind front cleaned screen rack. This operation principle avoids the accumulation of material in front of the screen and even extremely bulky objects are reliably removed by the screen rakes and transported upwards out of the channel.
The lower part of the TrashMax® consists in the steep conveying section followed by the upper part, the flat discharge section with a small inclination. This screen design guarantees the reliable discharge of screenings into a downstream transport or disposal system.
