ABSTRACT:
The invention relates to an apparatus for removing solid components from a fluid in a trough (1) having a transport device (3) in the form of a transport trough (4) and a rotationally driven transport helix (6), the transport device (3) having at one end a solids outlet (9) and at the opposite end a sieving surface (15) at least in portions of the surface, in which the solid components are able to be sieved out of the fluid and are able to be transported to the solids outlet (9) via the transport helix (6) in the axial direction of the transport device (3). In order to provide apparatus which can also process larger quantities of fluid and do so during variations in supply quantities, it is proposed that the transport device (3) have a sieving apparatus (19) between the solids outlet (9) and the sieving surface (15) located at the input side in the transport direction, whose sieving surface when projected upon the transport device (3) is larger than the diameter of the transport trough (4), the sieving apparatus (19) being located at the height of the maximum fluid level in the trough (1) and discharging sieved out solid components into the transport device (3).
