Filtration system for a water drainage system
View Patent ↗A downspout drain filter includes a housing and a filter media. The housing defines an internal cavity, an inlet to the internal cavity along a top of the housing, and an outlet from the internal cavity along a bottom of the housing. The filter media is disposed within the internal cavity. The filter media divides the internal cavity into an upper chamber and a lower chamber. The filter media is configured to trap debris in the upper chamber from fluid flowing downward through the internal cavity. The filter media is permeable such that the fluid flows from the upper chamber to the lower chamber.
1. A downspout drain filter comprising:
a housing defining (i) an internal cavity, (ii) an inlet to the internal cavity along a top of the housing, and (iii) an outlet from the internal cavity along a bottom of the housing, wherein the housing includes (a) front and back panels that are disposed between the top and bottom of the housing, (b) first and second side panels extending between the front and back panels, and (c) first and second sloped surfaces extending between the back panel and the first and second side panels, respectively, wherein the first and second sloped surfaces extend into the internal cavity such that the internal cavity tapers in the direction that extends from the top to the bottom of the housing along the first and second sloped surfaces; and
a filter plate (i) disposed within the internal cavity, (ii) dividing the internal cavity into an upper chamber and a lower chamber, (iii) configured to trap debris in the upper chamber from fluid flowing downward through the internal cavity, (iv) permeable such that the fluid flows from the upper chamber to the lower chamber, and (v) having a removable central portion that provides access to the lower chamber from the upper chamber when removed.
2. The downspout drain filter of claim 1 , wherein the removable central portion of the filter plate is configured to lock and unlock to and from a remainder of the filter plate via rotation relative the remainder of the filter plate.
3. The downspout drain filter of claim 2 , wherein (i) the removable central portion of the filter plate includes a first set of tabs, (ii) the remainder of the filter plate includes a second set of tabs, and (iii) the first set of tabs are configured to align with the second set of tabs to lock the removable central portion of the filter plate to the remainder of the filter plate.
4. The downspout drain filter of claim 3 , wherein (i) the remainder of the filter plate defines slots and (ii) the first set of tabs are configured to align with the slots to unlock the removable central portion of the filter plate from the remainder of the filter plate.
5. The downspout drain filter of claim 1 , wherein the filter plate includes ribs extending upward from an upper surface of the filter plate, and wherein the ribs are configured to separate the debris from the upper surface of the filter plate to facilitate flow of the fluid through the filter plate.
6. The downspout drain filter of claim 1 , wherein (i) the front panel defines an access opening, (ii) a door is disposed over the access opening, and (iii) the door has a third sloped surface that extends into the internal cavity such that the internal cavity tapers in a direction that extends from the top to the bottom of the housing along the third sloped surface.
7. The downspout drain filter of claim 6 , wherein the back panel is opposite of the front panel.
8. A downspout drain filter comprising:
a housing defining (i) an internal cavity, (ii) an inlet to the internal cavity along a top of the housing, and (iii) an outlet from the internal cavity along a bottom of the housing, wherein the housing includes (a) a back panel disposed between the top and bottom of the housing, (b) first and second side panels extending between the back panel and a front panel, and (c) first and second sloped surfaces extending between the back panel and the first and second side panels, respectively, wherein the first and second sloped surfaces extend into the internal cavity such that the internal cavity tapers in the direction that extends from the top to the bottom of the housing along the first and second sloped surfaces; and
a filter media (i) disposed within the internal cavity, (ii) dividing the internal cavity into an upper chamber and a lower chamber, and (iii) configured to trap debris in the upper chamber from fluid flowing downward through the internal cavity, and (iv) permeable such that the fluid flows from the upper chamber to the lower chamber, wherein the housing further defines an overflow opening along the top of the housing, and wherein the overflow opening is configured to direct the fluid out of the internal cavity in response to (a) the filter media becoming clogged and (b) the fluid filling the upper chamber.
9. The downspout drain filter of claim 8 , wherein the overflow opening is orientated at an angle relative to a front face of the housing.
10. The downspout drain filter of claim 9 , wherein the overflow opening is adjacent to and above the front face.
11. The downspout drain filter of claim 8 , wherein the overflow opening is grated.
12. The downspout drain filter of claim 8 , wherein the filter media includes a removable central portion that provides access to the lower chamber from the upper chamber when removed.
13. The downspout drain filter of claim 8 , wherein (i) the front panel disposed between the top and bottom of the housing, (ii) the front panel defines an access opening, (iii) a door is disposed over the access opening, and (iv) the door has a third sloped surface that extends into the internal cavity such that the internal cavity tapers in a direction that extends from the top to the bottom of the housing along the third sloped surface.
14. The downspout drain filter of claim 13 , wherein the back panel is opposite of the front panel.
