Abstract

1. Vortex cleaner for the cleaning of a paper stock suspension, with an essentially tapered, concave main body (2), with a tangentially placed inlet (1) located in the area with the largest diameter for the suspension to be cleaned, as well as a tapered, central guide body (4). The vortex cleaner has an essentially elbowed offset outlet for the accepts in its area of smallest diameter, enclosing a central discharge pipe (5) for lightweight particles, characterized at least in the initial area of the discharge pipe (5) for the lightweight particles by an essentially cylindrical outlet piece (6), which is arranged in smooth continuation to the tapered main body (2), which has a length in the discharge pipe (5) of the circular cylindrical piece of at least four times that of its inside diameter, and is at an essentially elbowed angle.
