Wwtp Preprocessing Rotary Drum Fine Screens

ROTARY RAKE DRUM SCREEN is designed for the fine screening of municipal and industrial waste water.
The SCREEN separates the solid from the wastewater, transporting and compacting the screening and can reach a dry percentage of 35%. The screen zone consists in a drum made by bars, a cleaning rake that rotates together with the screening conveying spiral. There is also a washing system and a system to clean the rake too. The spiral rotates on the U shape channel with the same mesh size as the spacing between the bars. The equipment consists in a drum screen made by bars at a certain distance and this distance is the screening size; a cleaning rake in the screening zone, a conveyor to transport the solid to the compaction and discharge zone.
It is easy to inspect in every part and this make the ordinary and extraordinary maintenance very easy.
 

ROTARY DRUM SCREEN with or without the compactor is a machine usable for solid/liquid 
separation in case of a big water flowrate.
This machine is composed by a screen basket in a holed sheet (circular holes from 2 to 6mm) or in a trapezoidal profile Wedge Wire stainless steel net (spacing 0.25mm - 2mm) which filter the waters holding back the solid particles.
This sieve rotates together with the transport screw and moves the resulting materials up to the compaction and dehydration zone where they'll be discharged allowing a reduction of volume and weight of that waste by over 40%.
The machine can be installed inclined ( 35 °  depending on the needs) into a concrete channel or in a stainless steel tank to receive the waste waters from a fixed pipe.

ROTARY DRUM SCREEN is supplied with a single gear motor which moves the screw and the sieve together, but it can be equipped with two separate gear motors (one for the screw rotation and one for the sieve rotation).
This version is particularly recommended when in the wastewater a large amount of solid waste to be filtered is present. The double motorization guarantees the independence of the two rotary elements of the machine (screw and sieve) and consequently a greater reliability and sturdiness of the entire system.

√  Grid gap range is wide 0.5~12mm;
√  It forms a 35° Angle with the water flow, which can greatly improve the separation of fine dirt.
√  The built-in flushing device can be cleaned automatically during operation, reducing blockage and low maintenance cost;
√  Compared with the traditional grille, the water flow is larger, the head loss is less, and the stacking plane in front of the grille is
    less;
√  High pollution interception efficiency, closed transport, no pollution to the environment;
√  The equipment can be fully automatic control, smooth operation, low energy consumption, low noise;
√  Integrated design of fishing, conveying and pressing treatment, compact structure and small footprint.
