An apparatus for collecting and removing solid particles from a flowing fluid (5) includes a grid unit (6) including a plurality of stationary bars (1) being arranged to form a stationary bar unit (3), each of the stationary bars (1) including a plurality of steps (8) and including a skeleton portion (9) and a rising portion (10). A plurality of movable bars (2) is arranged to form a movable bar unit (4), each of the movable bars (2) including a plurality of steps (8) and including a skeleton portion (9) and a rising portion (10). The stationary bars (1) and the movable bars (2) are arranged side by side to alternate. The steps (8) include an undercut (11, 13). A drive (25) moves the movable bar unit (3) along a closed path of movement (21) being substantially elliptical. The path of movement (21) includes a forward movement, an upward movement and a backward movement The path of movement (21) is coordinated with the shape of the steps (8) of the bars (1, 2) such that the skeleton portion (9) of the movable bars (2) is covered by the skeleton portion (9) of the stationary bars (1) during the forward movement and it is not covered thereby during the backward movement. The skeleton portion (9) of the movable bars (2) is covered by the rising portion (10) of the stationary bars (1) during the downward movement and it is not covered thereby during the upward movement.
