The present invention relates to solid material separators and, more particularly, a gravity separator that uses the upthrust of an upwardly flowing fluid to separate desired particulate from a material composite of a plurality of particulate.
Currently, when separating solid materials, gold prospectors, geology enthusiasts, and the like still utilize panning because of its cheap cost, portability and relatively simple and easy process. However, panning is time consuming and so a user may work but a limited amount of material. Furthermore, because panning requires hand agitation and spilling to separate the material, there is a learning curve as well as an opportunity for human error as it relates to the user's manual dexterity. Alternative means of separating solid materials involve the use of mercury of other toxic chemical elements.
As can be seen, there is a need for separating solid materials that is still, like panning, portable, has no moving parts, easy and inexpensive, yet lends itself to quicker results without the use of mercury and independent on the user's fine motor skills.
In one aspect of the present invention, a gravity particulate separator includes a vertically oriented flow tube forming at least one fluid inlet; an inlet tube fluidly communicating with the flow tube, wherein the inlet tube interfaces with the flow tube at an inlet angle and upward from the at least one fluid inlet; and an outlet tube fluidly communicating with the flow tube, wherein the outlet tube interfaces with the flow tube at an outlet angle and upward from the inlet tube so as to form a teetering chamber along the flow tube between the inlet tube and the outlet tube.
In another aspect of the present invention, gravity particulate separator includes a vertically oriented flow tube forming at least one fluid inlet; a fluid source fluidly connected to the at least one fluid inlet; an inlet tube fluidly communicating with the flow tube, wherein the inlet tube interfaces with the flow tube at an inlet angle and upward from the at least one fluid inlet; a collection container fluidly communicated with the flow tube downward from the at least one fluid inlet; and an outlet tube fluidly communicating with the flow tube, wherein the outlet tube extends approximately 8 inches to interface with the flow tube at an approximately 40 degree outlet angle and upward from the inlet tube so as to form a teetering chamber along the flow tube between the inlet tube and the outlet tube, wherein the flow, inlet and outlet tubes are made of transparent material and each tube forms a rectangular shape.
These and other features, aspects and advantages of the present invention will become better understood with reference to the following drawings, description and claims.
The following detailed description is of the best currently contemplated modes of carrying out exemplary embodiments of the invention. The description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of the invention, since the scope of the invention is best defined by the appended claims.
Broadly, an embodiment of the present invention provides a gravity separator that uses the upthrust of an upwardly flowing fluid to separate desired particulate from a material composite of a plurality of particulate. The gravity separator may include a vertically oriented flow tube that is fluidly connected to an inlet tube, an outlet tube and a collection container, wherein the outlet tube is oriented upward from the inlet tube, which in turn is upward from the collection container. The inlet tube may receive a material composite including a plurality of non-desired particulate, conforming desired particulate and non-confirming desired particulate, which are subject to upthrust through the segment of the flow tube between the inlet tube and the outlet tube, the teetering chamber, so that only the conforming desired particulate sinks to the collection container.
Referring to
The tubing 12, 14, 16 may be made of transparent material formed into a generally rectangular shape, defining a continuous square opening that a fluid may flow through and be visually perceived. The rectangular shape may be preferably to cylindrical shapes as it allows the outlet tube 16 and the inlet tube 14 to be disposed close to each other for the sake of compactness.
The manifold 26 may be fluidly connected to the flow tube 12 through at least one fluid inlet 28. The manifold 26 may fluidly interconnect the at least one fluid inlet 28 through piping 24 to a fluid valve 22 and a fluid pump 20 so as to provide a fluid source of fluid 34 urged to flow in an upwardly direction through the flow tube 12 at variable rates of flow. It should be understood that directional or orientation-related terms such as upward, vertical, downward and the like may be defined in relation to the direction of gravity relative to a generally horizontal supporting surface 17. The fluid valve 22 may be adapted to control the rate of flow of the fluid 34 through the flow tube 12 at a predetermined or desired rate.
The collection container 18 may be connected to the flow tube 12 downward from the fluid inlet 28, as illustrated in
At their fluid interface, the inlet tube 14 may be oriented at an angle to the flow tube 12 and then transition to a generally vertical orientation when it terminates in an inlet opening, as illustrated in
At their fluid interface, the outlet tube 16 may be oriented at an outlet angle to the flow tube 12. In certain embodiments, the outlet angle may be approximately 40 degrees to facilitate the capture of non-conforming configurations of a desired particulate. In certain embodiments, the length of the outlet tube 16 may be approximately 8 inches in length. The outlet tube 16 may form an outlet opening through which discharged flowing fluid 34 flows. A tailings container 30 may be disposed beneath the outlet opening so that the discharged flowing fluid 34 and any particulate (tailings) therein may be received in. In certain embodiments, the tailings container 34 may be fluidly connected to the outlet opening.
A method of using the present invention may include the following. The gravity separator 10 disclosed above may be provided. A user may engage the pump 20 and valve 22 so that a predetermine rate of flow of a fluid 34 is flowing upwardly through the flow tube 12. Then the user may load the inlet tube 14 with a material composite 36, in certain embodiments by means of the funnel 32, so that it is received between the inlet tube fluid interface and the outlet tube fluid interface—i.e., the teetering chamber, as illustrated in
Using this method, the user hoping to isolate a heaver desired particulate 38 in the collection container 18 may adjust the rate of fluid flow for this purpose. Moreover, the non-conforming desired particulate 40 may have at least one physical configuration, for example flakey physical property, whose density urges it through the outlet tube 16 along with the undesired particulate 42. Alternatively, the outlet angle and length of the outlet tube 16 may be dimensioned and adapted along with the teetering chamber so that the non-conforming desired particulate 40 will catch in a low velocity eddy loop until the end of a cycle, wherein it is drained away to be separately panned.
Referring to
It should be understood, of course, that the foregoing relates to exemplary embodiments of the invention and that modifications may be made without departing from the spirit and scope of the invention as set forth in the following claims.
