Abstract:
Sieving device for mechanically separating and extracting solid components, solid bodies, or solid matter from a liquid flowing in a sluice channel, in particular, sieve or filter grating for process, cooling water, or effluent currents or for use in sewage treatment plants or hydroelectric power stations,with a number of sieving panels which are substantially arranged in a transverse direction to the direction of flow of the liquid current, and which form a revolving endless sieve belt immersing into the liquid current, on which endless sieve belt a plurality of sieving panels which are sequentially arranged adjacent to one another in the direction of motion of the endless sieve belt form a common sieving surface in the sluice channel, and with a drive for the endless sieve belt, characterized in that the sieving panels are arranged successively on the endless sieve belt in such a way that the revolving motion of the endless sieve belt is substantially comprised within one single plane, wherein pivotal axes around which the sieving panels are pivoted at points of deflection of the endless sieve belt are perpendicular to the sieving surface.
