Mechanical grid is designed to separate solid particles contained in wastewater and then unloading them into mobile container or screw conveyor.
THE PRINCIPLE OF OPERATION
Mechanical grid is installed in reinforced concrete or steel tray through which municipal or industrial drain lows.
The grid consists of frame, gear motor, chain, tine arms, ilter screen, cleaner, protective covers, slewing bearings, duct seals, traverse,
drive gear and drive shaft. The grid is driven by the geared motor. Large mechanical impurities contained in wastewater are caught by
hooks and moved upward, along the rake, into the garbage bin. The gap width varies from 3mm to 10mm. The grid elements are self-cleaning when the sharp ends enter the space between the traverses. The self-cleaning process is completed with a rotating brush.
