This invention describes an overflow system for a slurry storage chamber which chamber has a slurry input pipe tangentially mounted through a side wall of the tank to create a vortex. The overflow portion is designed to have a pressure confining top to the tank with the overflow pipe connected near the center of the top. A conically shaped baffle is inserted in the tank with its axis aligned with the axis of the overflow pipe and positioned immediately below the overflow pipe. The overflow configuration provides a means for separating the particles from the fluids passing out through the overflow pipe.

Overflow for slurry tank

Slurries containing solid liquids and gases are continuously separated into individual components utilizing a revolving vanes on an eccentric axis. The vanes are of a flexible material which revolve sufficiently slowly that in sequence gas escapes through an overhead mesh, water is separated through a lower mesh and solids exit through a lower opening. The slurry input is from the axis plane overhead of the axis and input rate is balanced with gas, water and solids output.
