ABSTRACT:
A separating grid (1) for collection and removal of solid particles and objects (4) from running water (2) in a channel (2). The separating grid (1) comprises a stand (9) including a separating unit (10) formed by separating grid bars (11, 12) positioned side by side in such a manner that fixed grid bars (11) alternate with mobile grid bars (12), said grid bars formed with collection and removal means (13). The fixed grid bars (11) are securely attached to the stand whereas the mobile grid bars (12) are connected at their upper ends (17) to a drive unit (18) and at their lower ends (16) they are arranged for controlled movement in the stand. The drive unit imparts to the mobile grid bars a movement which at the upper end of the bars follows a closed path but in a direction towards their lower ends follows successively and increasingly flattened, elliptical paths changing at the lower ends into an essentially rectilinear to-and-fro movement path. According to this arrangement, the mobile grid bars carry, by means of their collection and removal means, the objects step by step upwards along the collection and removal means of the fixed grid bars, up to a discharge (19) for removal.
