Abstract
A filter device for removing particles from a fluid includes a fluid chamber and an inlet for fluid, an outlet for filtered fluid and an outlet for particles, each coupled to the fluid chamber. The filter device also includes a flow directing mechanism for inducing a vortex flow around a vortex axis in the fluid chamber. The outlet for particles is coupled to the fluid chamber at a location substantially perpendicular to the vortex axis.
Claims18
A filter device for removing particles from a liquid, the filter device comprising:
- a fluid chamber;
- an inlet for liquid;
- an outlet for filtered liquid;
- an outlet for particles;
- a sieve;
- a flow directing mechanism for inducing a vortex flow around a vortex axis in said fluid chamber;
- and
- an inlet chamber coupled to the inlet;
- wherein the outlet for particles is coupled to the fluid chamber at a location substantially perpendicular to the vortex axis;
- wherein the inlet for liquid, the outlet for filtered liquid, and the outlet for particles are each coupled to the fluid chamber;
- wherein the sieve is arranged in the fluid chamber and upstream from the outlet for filtered liquid;
- wherein the inlet chamber is delimited from the fluid chamber by a wall member;
- wherein the wall member comprises at least one opening being shaped to induce the vortex flow in the fluid chamber;
- and
- wherein the inlet chamber comprises an inlet chamber sieve for sifting the liquid upstream from the wall member.
