A Device for sucking up particles from the bottom (2) of a circular liquid container (1) consists of a swingable tube-shaped arm (3) along the bottom (2) of the container (1), which with its inner end (4) is housed at the centre (5) of the container (1), where it is connected to a sucking device (6) for the sucking up of particles from the bottom (2) of the container (1) at turned openings (7) against the bottom (2) in the tube-shaped arm (3), whereby the tube-shaped arm (3) is designed to convey its swinging motion to the water, which is designed to supply the container (1) in a tangential direction. According to the invention, the inner end (4) of the tube-shaped arm (3) is housed at an outlet pipe (6) in the bottom (2) of the container (1), in which the outlet pipe (6) makes up the sucking device. In addition, the tube-shaped arm (3) at its outer end is equipped with one or more support wheels, which are designed to hold the arm's (3) distance from the bottom (2) constant. Finally, the openings along the pipe-shaped arm (3) are turned against the slits (7) in bottom of the container (1).<IMAGE> |
