Abstract: A conveyor scraper for use in an apparatus for separating cake from liquid is disclosed. The apparatus comprises a reservoir for holding cake containing liquid and a continuous conveyor inclined upward from a surface of the liquid. A plurality of outward extending scrapers are movable with the conveyor and engage are inclined wall spaced below and parallel to the conveyor to move the cake along the wall. The scraper is pivotably mounted to the conveyor to permit the scraper to pivot upon encountering an obstruction to avoid stalling or otherwise damaging the conveyor. The scraper is biased into engagement with the inclined wall permitting movement of the scraper toward the wall as wear occurs.

Abstract: An apparatus for separating pigment containing cake from a vehicle such as water is disclosed. The apparatus comprises a skimmer which includes a reservoir for containing the cake containing vehicle and a continuous conveyor belt inclined upward from a surface of the cake containing vehicle. In a preferred embodiment a plurality of upward extending walls are attached to the conveyor belt for skimming the cake from the vehicle. An inclined wall is disposed parallel to a space below the belt to slidingly engage the outward extending walls as they move therepast. A lower portion of the inclined wall is positioned over the reservoir, and an upper portion of the inclined wall extends outward from the reservoir, with the lower portion of the inclined wall perforated to allow vehicle to drain from the cake into the reservoir thus separating the cake and the vehicle. A discharge opening formed at an upper end of the inclined wall allows the separated cake to be discharged into a receptacle for collection.
