Apparatus for collecting and removing solid particles from a flowing fluid

A separating grid for collecting and removing solid particles from flowing waste water, comprising:

• a grid unit to extend into the flowing waste water including:
• a plurality of stationary first bars being arranged to form a first bar unit, each of said stationary first bars including a plurality of steps facing the flowing direction of the water and including a skeleton portion and a rising portion;
• and
• a plurality of movable second bars being arranged to form a movable second bar unit, each of said movable second bars including a plurality of steps facing the flowing direction of the fluid and including a skeleton portion and a rising portion, said stationary first bars and said movable second bars being arranged side by side to alternate;
• two stationary bearings each having a pivot axis;
• a first parallelogram unit being connected to said two stationary bearings to be pivotable in a plane about the pivot axes of said stationary bearings with respect to said stationary first bar unit;
• a second parallelogram unit being operatively connected to said first parallelogram unit and to said movable second bar unit, said first and second parallelogram unit being designed and arranged to guide said movable second bar unit in a plane with respect to said stationary first bar unit;
• and
• a drive being operatively connected to said movable second bar unit to move said movable second bar unit along a closed path of movement including an upwardly directed component of movement being greater than the vertical height of said steps of said first and second bars, said drive being operatively connected to said second bar unit.
