Abstract
A material classification device for separation of solid materials, having a relatively high specific gravity, from a stream of fluid and solid material. The device is particularly suited for the extraction of gold from alluvial material. The device generally comprises an open conduit that has a first opening and a second opening therethrough. A container is attached to the bottom of the conduit so that the openings are in fluid flow communication with the container. A portion of the flow of fluid and materials passes through the first opening and is captured in the container. A tube passes into the container with an aperture therein so that a fluid may be passed into the container to agitate the material collected therein freeing the lighter material so that it can exit the container out the second opening.
Claims14
A device for separating a portion of entrained solid materials from a stream of fluid and material, said device comprising:
- an open conduit having an interior, a bottom portion, an open inlet end, and an open outlet end, said bottom portion having a first opening therethrough and a second opening therethrough, and said conduit further comprising a mid portion extending between said first opening and said second opening, an inlet portion including said inlet end, and an outlet portion including said outlet end;
- a container comprising a hollow body having an interior, a bottom, at least one side, and an open top, said open top being attached to said bottom portion such that said interior of said conduit is in fluid flow communication with said interior of said container through said first opening and said second opening, whereby a portion of a stream of fluid and material moving from said inlet end to said outlet end passes through said mid portion of said conduit and out said outlet end, and the remaining portion of the stream of fluid and material passes through said first opening, a portion of the material is captured in said container and the remaining portion of the fluid and material passes through said second opening and out said outlet end;
- at least one tube having a first end and an open second end, said first end of said tube passing through said side of said container so that at least a portion of said tube extends into said container, said portion of said tube within said container having at least one aperture therein;
- and
- a scoop having a first end, a second end, said scoop being attached to said bottom portion of said conduit and said first end of said scoop being attached to said container such that said second end of said tube is in fluid flow communication with said scoop.
A device for separating a portion of entrained solid materials from a stream of fluid, said device comprising:
- an open conduit having an interior, a bottom portion, an open inlet end, and an open outlet end, said bottom portion having a first opening therethrough and a second opening therethrough, said first opening have a first longitudinal edge upstream of said first opening and a second longitudinal edge downstream of said first opening, said second opening having a first longitudinal edge upstream of said second opening and a second edge downstream of said second opening, and said conduit further comprising a mid portion extending between said first opening and said second opening, an inlet portion including said inlet end, and an outlet portion including said outlet end;
- a container comprising a hollow body having an interior, a bottom, at least one side, and an open top, said open top having a rim, said rim being attached to said bottom portion of said conduit such that said interior of said conduit is in fluid flow communication with said interior of said container through said first opening and said second opening, said portion of said rim proximal to said second edge of said second opening being spaced apart from said second edge of said second opening, whereby a portion of a stream of fluid and material passes through said mid portion of said conduit and out said outlet end, and the remaining portion of the stream of fluid and material moving from said inlet end to said outlet end passes through said first opening, a portion of the fluid and material is captured in said container and the remaining portion of the fluid and material passes through said second opening and out said outlet end;
- at least one tube having a first end and an open second end, said first end of said tube passing through said side of said container so that at least a portion of said tube extends into said container, said portion of said tube within said container having at least one aperture therein;
- and
- a scoop having a first end, a second end, said scoop being attached to said bottom portion of said conduit and said first end of said scoop being attached to said container such that said second end of said tube is in fluid flow communication with said scoop.
