Abstract:
An apparatus for controlling the density from a reclamation slurry tank or silo includes apparatus for adding slurry to the tank, an overflow from the tank which communicates with a sump, and reclamation apparatus mounted toward the bottom of the tank. The reclamation apparatus essentially comprises a bell mouthed pipe directed downwardly and exiting horizontally from the tank. The pipe is connected to a pump for removing slurry accumulating at the bottom of the tank. The pipe also includes apparatus for measuring the density and/or flow through the pipe. The density from the tank is controlled by a fluid inlet mounted between the bell mouth and the pump which forces fluid into the pipe in accordance with the measured flow or density as compared to a predetermined flow or density. To facilitate the operation, various fluidizing jets are included around the bell mouth and around the bottom of the tank.
