MODELS SCREENING EQUIPMENT
EM31G - AUTOMATIC FINE SCREEN WITH SELF-CLEANING FILTERING ELEMENTS IN PLASTIC MATERIAL
|Application||Screening of civil and industrial waste water|
|Characteristics||The machine is equipped with a filtering continuous belt made of acetalic resin elements (teeth+rollers) and stainless steel shafts. Cleaning brush and washing system.|
|Operation||The waste water containing suspended particles goes through the filtering elements which hold the material in suspension. This material is lifted and removed by a rotary cleaning brush and a washing system.|
|Materials||Compact machine: stainless steel.|
|Installation||In a concrete channel.|
|Channel width||From 300 to 2000 mm.|
|Degree of filtration||3 or 6 mm.|
|Advantages||Continuous filtration, suitable even for water containing filaments of fibers.|
|Disadvantages||Not suitable to remove solid materials larger than 250 mm..|
|Optional||Electromagnetic coupling with alarm sensor.
Double cleaning brush (motorized).
The machine operation is controlled by a Pause-ON timer.
If the water level upstream the filtering screen should increase and exceed a pre-set threshold, a level measurer can start the machine, even during the pause phase.
The filtering belt lifts continuously the solids held by the plastic material elements.
At the top, the screened material is discharged thanks to the teeth movement, a rotary brush and two washing systems which furtherly take off the screened material.
The grit in the water may wear the rollers placed on the cleaning teeth supporting shafts sides. The rollers shafts are protected against wear by some bushes fixed to the shafts. The rollers are made of plastic material, are low cost as mass-produced and can be easily replaced.
The sliding guides for the chains are bolted to the frame and can be easily replaced.
