Abstract
A high-pressure injection hydraulic transport system for conveying solids comprises a pressurizable hopper, a peristaltic pump conveyor, multiple air domes, and means for injecting air into the pumped slurry, such that a "beachcomber" effect is produced in the slurry to maintain the solids in suspension. The peristaltic pumping sequence provides at least two open pumps between a non-adjacent pumping pump and closed pump.
Claims4
A high-pressure injection, hydraulic transport system for conveying fluidized solids comprising a pressure hopper for receiving the solids, means for pressurizing said hopper with a liquid pressurizing medium, said liquid pressurizing medium producing a slurry when mixed with the solids, a peristaltic pump conveyor for transporting said slurry, and means for diluting said slurry pumped by said peristaltic pump conveyor to a predetermined volume of concentration of the solids and for further transporting said diluted slurry.
