Abstract

An electrostatic particle collector may generally include a housing having sidewalls extending lengthwise between a first end and a second end. The housing may define a plate slot that extends heightwise within the housing between a top end and a bottom end. The housing may further include a plate access window that provides access to the bottom end of the plate slot. The collector may also include a collector plate configured to be installed within the plate slot that extends heightwise between a top edge and a bottom edge. Additionally, when the collector plate is installed within the plate slot, the bottom edge of the collector plate may be accessible from an exterior of the housing via the plate access window so as to allow the bottom edge of the collector plate to be moved relative to the housing to facilitate removal of the collector plate from the housing.

First claim

What is claimed is:

1. An electrostatic particle collector, comprising:
a housing including first and second sidewalls extending lengthwise between a first end and a second end, the housing defining a plate slot that extends heightwise within the housing between a top end and a bottom end, the housing further including a plate access window defined through the housing so as to provide access to the bottom end of the plate slot;
a collector plate configured to be installed within the plate slot, the collector plate extending heightwise between a top edge and a bottom edge and lengthwise between a first side edge and a second side edge,
wherein, when the collector plate is installed within the plate slot, the bottom edge of the collector plate is accessible from an exterior of the housing via the plate access window so as to allow the bottom edge of the collector plate to be moved in the direction of the top end of the plate slot to facilitate removal of the collector plate from the housing.

2. The electrostatic particle collector of claim 1 , wherein the housing further defines a second plate slot that extends heightwise within the housing between a top end and a bottom end, the housing including a second plate access window defined through the housing so as to provide access to the bottom end of the second plate slot.

3. The electrostatic particle collector of claim 2 , further comprising a second collector plate configured to be installed within the second plate slot, the second collector plate extending heightwise between a top edge and a bottom edge and lengthwise between a first side edge and a second side edge,
wherein, when the second collector plate is installed within the second plate slot, the bottom edge of the second collector plate is accessible from the exterior of the housing via the second plate access window so as to allow the bottom edge of the second collector plate to be moved in the direction of the top end of the plate slot to facilitate removal of the second collector plate from the housing.

4. The electrostatic particle collector of claim 1 , further comprising a grounding device configured to extend through a ground opening defined through the housing so as to electrically contact an outer face of the collector plate.

5. The electrostatic particle collector of claim 4 , wherein the grounding device is configured to apply an inward force against the outer face of the collector plate such that an opposite inner face of the collector plate is pressed against an inner surface of the plate slot.

6. The electrostatic particle collector of claim 1 , further comprising a corona wire assembly configured to be at least partially installed within the housing.

7. The electrostatic particle collector of claim 1 , further comprising a fan configured to be installed within the housing.

8. The electrostatic particle collector of claim 1 , wherein an inlet orifice is defined at or adjacent to the first end of the housing and an outlet orifice is defined at or adjacent to the second end of the housing.

9. The electrostatic particle collector of claim 1 , wherein the inlet orifice is defined by an inlet nozzle configured to be removably coupled to the housing.

10. The electrostatic particle collector of claim 1 , further comprising an input port associated with housing, the input port being configured to be coupled to a separate control device.

11. A method for removing and/or installing components used within an electrostatic particle collector, the electrostatic particle collector including a housing and a collector plate, the housing including first and second sidewalls extending lengthwise between a first end and a second end of the housing, the housing defining a plate slot adjacent that extends heightwise within the housing between a top end and a bottom end, the method comprising:
accessing, when the collector plate is installed within the housing, a bottom edge of the collector plate via a plate access window defined through the housing, the plate access window being defined through the housing at a location adjacent to the bottom end of the plate slot; and
applying a force against the bottom edge of the collector plate so as to cause the collector plate to move relative to the housing in the direction of the top end of the plate slot.

12. The method of claim 11 , wherein applying the force against the bottom edge of the collector plate comprises applying the force against the bottom edge such that the collector plate is moved relative to the housing until a clearance distance is defined between a top edge of the collector plate and the top end of the plate slot.

13. The method of claim 12 , further comprising contacting portions of opposed side edges of the collector plate extending along the clearance distance defined between the top edge of the collector plate and the top end of the plate slot.

14. The method of claim 13 , further comprising removing the collector plate from the plate slot by contacting the opposed side edges and moving the collector plate away from the housing.

15. The method of claim 11 , further comprising installing the collector plate within the housing by inserting the bottom edge of the collector plate through the top end of the plate slot.

16. The method of claim 15 , further comprising moving the collector plate relative to the housing until the bottom edge of the collector plate is located adjacent to the bottom edge of the plate slot and is accessible via the plate access opening.

17. The method of claim 11 , further comprising positioning a grounding device relative to the housing such that a portion of the grounding device extends through a ground opening defined in the housing and contacts an outer face of the collector plate.

18. The method of claim 17 , wherein the grounding device is configured to apply an inward force against the outer face of the collector plate such that an inner face of the collector plate is pressed against an inner surface of the plate slot.

19. The method of claim 11 , wherein the electrostatic particle collector further comprises a corona wire assembly, further comprising installing a portion of the corona wire assembly into the housing via a wire slot defined through the housing.

20. The method of claim 11 , wherein the electrostatic particle collector further comprises a removable cover configured to be coupled to a wall of the housing so as to cover the plate slot, further comprising removing the cover from the housing prior to moving the collector plate relative to the housing.
