Abstract
An apparatus and method are disclosed for the continuous treatment of the flow of a mixture containing liquids and solids. A pump provides the mixture to tube that includes a woven material. The liquid is filtered from the mixture, leaving a solids-enriched mixture in the tube. The tube may be flexed during the process, freeing solids trapped in the tube to flow through the center of the tube. A valve may be provided to the tube to generate a back-pressure in the system.
Claims7
An apparatus to treat a slurry to form a solids-enriched portion of the slurry and a solids-depleted portion of the slurry, said apparatus comprising:
- a frame;
- a positive displacement pump having an input to accept a continuous slurry flow and an output to provide the continuous slurry flow at an elevated pressure;
- a motor for powering said pump;
- a valve including a piston, linkage and a valve wheel;
- a passageway having a first end connected to said pump output, and a second end attached to said valve, wherein a length of said passageway is an open weave material;
- a first manipulation mechanism including a wheel attached to a flywheel;
- and
- a trough, wherein said first manipulation mechanism, said valve and said trough are mounted to said frame, and wherein said positive displacement pump provides a continuous flow of slurry into said passageway, and wherein said first manipulation mechanism acts on said passageway in conjunction with said valve to force a portion of liquid contained in said slurry through said open weave to provide a solids-enriched portion of slurry at said second end.
