A hydrocyclone for the separation of a liquid suspension into accept and reject fractions, having a conically converging classification pipe, at the apex of which there is an opening for the reject fraction, and a base part in which there is an axial pipe for the accept fraction, and a minimum of two feed channels for the liquid suspension to be purified, in which the feed channel directs the liquid suspension onto an incline in the circular space between the classification pipe and the accept fraction outlet pipe, and the liquid suspension spray discharges from the incline over the spray in the following feed channel.

Hydrocyclone

The connecting pipe portion between the outlet pipe and the drain pipe of a wash basin is surrounded by an electric heater for heating the interior of the connecting pipe portion to a temperature of about 80.degree. to 100.degree.C to prevent microbes from rising from the drain pipe into the outlet pipe. The connecting pipe portion comprises a metal ring having a heating coil wound thereon and being thermally insulated from the outlet pipe and drain pipe by insulating rings. The outlet pipe may include a conical stub pipe projecting into the ring and spaced therefro by an air gap.
