Separator and method of separating

A separator for separating a waste stream comprising liquid constituents, small-sized solid constituents and large-sized solid constituents into a first waste stream comprising the large-sized solid constituents and a second waste stream comprising the liquid and the small-sized solid constituents, the separator comprising:

• a stationary base;
• a housing fixedly connected to the stationary base, the housing comprising an inlet for supply of the waste stream to be separated, a first outlet for discharge of the first waste stream and a second outlet for discharge of the second waste stream;
• a vibrating mesh screen arranged inside the housing downstream of the inlet for receiving on a vibrating mesh screen surface the waste stream to be separated, wherein the vibrating mesh screen is configured to be vibrated in order to move the waste stream over the vibrating mesh screen surface, wherein a mesh size of the vibrating mesh screen is selected to allow passage of the liquid and small-sized solid constituents towards a receptacle inlet opening and to move the large-sized solid constituents over the vibrating mesh screen surface towards a peripheral edge of the vibrating mesh screen;
• a vibrating receptacle arranged inside the housing downstream of the vibrating mesh screen and connected to the vibrating mesh screen, the vibrating receptacle comprising a receptacle inlet opening and a receptacle passage for receiving the second waste stream having passed the vibrating mesh screen and for guiding the second waste stream towards the second outlet, respectively;
• a vibrating support fixedly connected to the vibrating receptacle, the vibrating support being spring-mounted on the stationary base;
• a drive unit mounted to the vibrating support, the drive unit being configured to induce vibration to the vibrating support and to the vibrating receptacle and vibrating mesh screen connected thereto, wherein the mutually connected vibrating mesh screen, vibrating receptacle, and vibrating support are arranged to be vibrateable with respect to the stationary base and the housing;
• and
• a collector arranged inside the housing downstream of the vibrating mesh screen, the collector comprising a collecting surface for collecting the large-sized solid constituents of the first waste stream and discharging the large-sized solid constituents of the first waste stream towards the first outlet;
• wherein the vibrating mesh screen is sized and positioned to provide a gap between the peripheral edge of the vibrating mesh screen and a side wall of the housing connected to the stationary base, allowing the large-sized solid constituents of the first waste stream to drop onto the collecting surface of the collector.
