Abstract
A wear shoe for mounting to a flight of a sludge collector. The wear shoe snaps into a surface of the flight at a desired location and is held in place with no additional fasteners or hardware. The wear shoe is able to be utilized with any channel-type flight configuration.
Claims5
An elongated collector flight assembly for use in a wastewater treatment tank, the wastewater treatment tank having a flight supporting surface, and the collector flight assembly comprising:
- an elongated collector flight adapted to extend across the wastewater treatment tank and to be moved along the tank,
- the elongated collector flight including a bore,
- a wear shoe secured to the elongated collector flight for sliding engagement with the flight supporting surface,
- the wear shoe including a wear plate portion having a wear surface for slidably engaging the flight supporting surface and having an opposite surface engaging the flight, and
- the wear shoe including a locking member integral with the wear plate portion and projecting from said opposite surface into said bore to secure the wear shoe to the collector flight in snap fit relation, the locking member including a pair of spaced apart resilient legs, the resilient legs being adapted to resiliently move together when the locking member is forced into the bore and to grippingly engage the bore.
A wear shoe for use with a collector flight in a wastewater treatment tank, the collector flight extending across the wastewater treatment tank and adapted to move along the tank with the collector flight slidably supported at its opposite ends by flight supporting surfaces of the tank, and the collector flight having a bore, the wear shoe comprising:
- a wear plate portion having a wear surface for slidably engaging one of said flight supporting surfaces of the tank and having an opposite surface engaging the collector flight, and the wear shoe including a locking member integral with the wear plate portion and projecting from said opposite surface into said bore to secure the wear shoe to the collector flight in snap fit relation, the locking member including a pair of spaced apart resilient legs, the resilient legs being adapted to resiliently move together when the locking member is forced into the bore and to grippingly engage the bore.
An elongated collector flight assembly for use in a wastewater treatment tank, the wastewater treatment tank having a flight supporting surface, and the collector flight assembly comprising:
- an elongated collector flight adapted to extend across the wastewater treatment tank and to be moved along the tank,
- the elongated collector flight including a cylindrical bore,
- a wear shoe secured to the elongated collector flight for sliding engagement with the flight supporting surface,
- the wear shoe including a wear plate portion having a wear surface for slidably engaging the flight supporting surface and having an opposite surface engaging the flight, and
- the wear shoe including a resilient locking member integral with the wear plate portion and projecting from said opposite surface into said cylindrical bore to secure the wear shoe to the collector flight in snap fit relation, the wear shoe including a web and forming the wear plate portion at least one resilient leg extending from said opposite surface and being adapted to resiliently move when the locking member is forced into the cylindrical bore and to grippingly engage the bore.
