Material separator
A material separator removes material such as sand from a fluid utilizing an inclined housing having a fluid flow inlet in a lower portion of the housing. Higher density material descends by gravity to a lower wall of the inclined housing and continues to travel down the lower wall portion to a lower section of the housing where it is removed. The remaining fluid which may contain a liquid and a gas is removed from the housing via an outlet at the upper portion of the housing.
1. A separator for separating solid material from a fluid comprising:
an elongated inclined housing having an inlet for fluid, an outlet in an upper portion of the housing and an outlet for separated solid material at a lower portion of the housing;
a fluid discharge outlet within a lower portion of the housing for directing fluid toward an upper side wall of the housing; and
means for retarding the flow of fluid positioned within the housing vertically above the fluid discharge outlet and extending downwardly to a position adjacent a lower wall of the housing to allow separated solid material to fall downwardly along the lower wall of the housing to the outlet for separated solid material.
2. The separator of claim 1 wherein the means for retarding the flow of fluid includes one or more velocity shields comprising a paddle portion and a projection having a notch therein for securing the shield within the housing.
3. A separator according to claim 2 wherein the paddle portion comprises an arcuate plate.
4. A separator according to claim 2 further comprising a rod extending within the housing, the velocity shields extending downwardly from the rod.
5. A separator according to claim 1 wherein the housing is a circular tube and the fluid discharge outlet is located in a centrally located pipe in fluid communication with the inlet, the discharge outlet being located in an upper portion of the pipe wall to direct the fluid in an upward direction.
6. Apparatus for separating solid material from a fluid comprising a plurality of separators as claimed in claim 1 , an inlet manifold connected to each separator inlet, and an outlet manifold connected to each separator fluid outlet.
7. The separator according to claim 1 wherein the means for retarding the flow of fluid is spaced from the lower wall of the housing thereby forming a passageway for the solid material to fall downwardly.
8. The separator according to claim 1 wherein the means for retarding the flow of fluid comprises a plurality of axially spaced planar member that are supported within the housing and have a lower end that is adjacent to but spaced from the lower wall of the housing.
9. A method of separating solid material from a fluid which may contain liquids, solids and gases comprising:
directing the fluid through a discharge outlet in an upwardly direction within an elongated housing that is supported at an incline;
providing a separated solid material outlet in a bottom portion of the housing;
providing a fluid outlet in an upper portion of the housing; and
retarding the flow of fluid in a downward direction by placing one or more velocity shields vertically above the discharge outlet, the velocity shield extending downwardly to a position adjacent a lower wall portion of the housing to allow separated solid material to fall downwardly along the lower wall portion of the housing to the outlet for separated solid material.
10. The method according to claim 9 wherein the fluid contains solid material, a liquid and a gas.
11. The method of claim 9 including a plurality of axially spaced velocity shields that are planar members having a lower end adjacent to but spaced from the lower wall of the housing thereby forming a passageway for the solid material to fall downwardly.
