Wash bucket dirt filter

A filter for filtering particles in a container of fluid, the filter comprising:

• a flow director comprising a hub, a plurality of radial blades extending from the hub and intersecting with a plurality of vanes concentric about the hub, the plurality of radial blades and the plurality of concentric vanes defining a first face and an opposed second face, the radial blades and concentric vanes further defining a plurality of openings, each opening extending between the first face and the second face,
• each of the concentric vanes in the form of an inverted V-shaped trough having a closed end and an open end, wherein the closed end of the trough forms a top edge of the concentric vane and the open end of the trough forms a bottom edge of the concentric vane,
• the V-shaped troughs decreasing a cross-sectional area of each opening from the first face to the second face;
• and
• a skirt coupled to a perimeter of the flow director for maintaining the flow director in spaced relation from a bottom of the container, thereby compartmentalizing the container so that the flow director acts as a divider between fluid above and below the flow director,
• wherein the decrease in cross-sectional area of the openings helps to prevent particles from travelling from a position below the flow director to a position above the flow director,
• wherein the skirt and an outermost concentric vane are spaced apart to form a fluid return region therebetween, the fluid return region including fluid return passageways allowing fluid directed to the fluid region to flow from a position below the flow director to a position above the flow director, and
• wherein the fluid return passageways have a bottom rim formed by the outermost concentric vane and a top rim formed by the skirt, such that as fluid travels upwardly through the fluid return passageways drag exerted on the fluid by the bottom rim helps to direct fluid downwardly back through the flow director.

A filter for filtering particles in a container of fluid, the filter comprising:

• a flow director comprising a hub, a plurality of radial blades extending from the hub and a plurality of vanes concentric about the hub, the blades and the vanes intersecting to form a grid having a first face, an opposed second face, and a perimeter, the radial blades and concentric vanes collectively defining a plurality of openings formed therebetween, each opening extending between the first face and the second face where a cross-sectional area of each opening decreases from the first face to the second face;
• and
• a skirt coupled to the perimeter of the flow director for maintaining the flow director in spaced relation from a bottom of the container, the skirt compartmentalizing the container so that the flow director acts as a divider between fluid above and below the flow director,
• wherein the skirt and an outermost concentric vane are spaced apart to form a fluid return region therebetween, the fluid return region including fluid return passageways allowing fluid directed to the fluid return region to flow from a position below the flow director to a position above the flow director′
• wherein the fluid return passageways have a bottom rim formed by the outermost concentric vane and a top rim formed by the skirt, such that as fluid travels upwardly through the fluid return passageways, drag exerted on the fluid by the bottom rim helps to direct at least some of the fluid passing through the fluid return passageways downwardly back through the flow director.
