Abstract
An apparatus to remove sludge from a reservoir of liquid. A downwardly opening enclosure is positioned atop the floor of a reservoir with the enclosure having inlets for sludge and liquid to flow into the cavity. The cavity includes a channel for the sludge and liquid to flow upward in the channel which increases in size. Gas emitters on the edge portions of the enclosure assist the flow of sludge and liquid into the cavity.
Claims14
An apparatus for removing sludge from a reservoir of liquid having a reservoir floor comprising:
- an enclosure forming a cavity with edge portions extending over a reservoir floor;
- spacers beneath said edge portions positionable above the floor of a reservoir of liquid when inserted therein forming inlets between said edge portions, spacers and said floor for sludge and liquid in said reservoir to flow into said cavity;
- a gas emitting device having outlets adjacent said edge portions to emit gas into said cavity of said enclosure drawing liquid and sludge via said inlets into said cavity;
- a structure positionable atop the floor and within said enclosure to define a channel within said cavity between said structure and said enclosure for said liquid and sludge to flow through said channel from said inlets;
- an outlet leading from said channel for said liquid and sludge to flow out of said cavity, and wherein:
- said enclosure includes an outer cone with an inward facing surface, said structure includes an inner cone with a top and is positioned within said outer cone and further has an outer surface facing said inward facing surface of said outer cone, said inward facing surface and said outer facing surface forming said channel which increases in size in a direction from the floor to said top of said inner cone;
- and further comprising:
- a liquid pump connected to said outlet to move said liquid and sludge from said cavity;
- and,
- a gas booster outlet positioned at said top of said inner cone assisting flow of said liquid and sludge in said cavity toward said outlet.
The combination of:
- a reservoir with a reservoir floor and having foreign material mixed with water within said reservoir;
- a housing positioned atop said floor and having a downwardly facing surface cooperatively with said floor defining a cavity, said housing having bottom portions restable atop said floor with inlets provided for foreign material and water from said reservoir to flow into said cavity;
- a structure located within said cavity cooperatively with said housing defining a channel through which said foreign material and water flow;
- gas outlets located along said bottom portions of said housing directing gas into said channel carrying foreign material and water through said inlets into said channel;
- and,
- a reservoir outlet in communication with said channel to direct said foreign material and water to flow outwardly from said housing and said reservoir;
- said housing is an outer shell with an inwardly facing surface and said structure is positioned within said housing and has an outwardly facing surface spaced apart from said inwardly facing surface forming said channel which is conical in shape and increases in size as said housing and structure extend upwardly with said foreign material and water flowing upwardly through said channel;
- and,
- a gas booster outlet located atop said structure to direct gas upwardly carrying said foreign material and water in said channel.
The combination of:
- a reservoir with a reservoir floor and having foreign material mixed with water within said reservoir;
- a housing positioned atop said floor and having a downwardly facing surface cooperatively with said floor defining a cavity, said housing having bottom portions restable atop said floor with inlets provided for foreign material and water from said reservoir to flow into said cavity;
- a structure located within said cavity cooperatively with said housing defining a channel through which said foreign material and water flow;
- gas outlets located along said bottom portions of said housing directing gas into said channel carrying foreign material and water through said inlets into said channel;
- and,
- a reservoir outlet in communication with said channel to direct said foreign material and water to flow outwardly from said housing and said reservoir, and wherein:
- said housing is an outer shell with an inwardly facing surface and said structure is positioned within said housing and has an outwardly facing surface spaced apart from said inwardly facing surface forming said channel which increases in size as said housing and structure extend upwardly, and further comprising:
- a base upon which said housing is mounted with said base positioned atop said reservoir floor and extending outwardly from said housing within said reservoir to keep said structure upright,
- a booster gas outlet atop said structure within said shell directing said foreign material and water from said channel to said reservoir outlet.
An apparatus for removing sludge from a reservoir of liquid having a reservoir floor comprising:
- a downwardly opening enclosure forming a cavity with edge portions;
- means on said enclosure spacing said edge portions above a floor of a reservoir of liquid when inserted therein forming inlets between said edge portions and said floor for sludge and liquid in said reservoir to flow into said cavity;
- gas emitters on and extending along said edge portions operable to emit gas into said cavity of said enclosure drawing liquid and sludge via said inlets into said cavity;
- an outlet leading from said cavity for liquid and sludge to flow out of said enclosure;
- a flow direction device positioned within said cavity between said edge portions directing the liquid and sludge upwardly within said cavity;
- and,
- a liquid pump connected to said outlet to move said liquid and sludge from said cavity, said enclosure has a cavity downwardly facing surface, said flow direction device has an upwardly facing surface opposed to said cavity downwardly facing surface defining a channel through which liquid and sludge from said inlets flow:, and further comprising:
- a booster gas emitter mounted to and extending atop said flow direction device emitting gas to assist upward flow of liquid and sludge.
An apparatus for removing sludge from a reservoir of liquid having a reservoir floor comprising:
- an elongated and downwardly opening enclosure having length with a first end and a second end and forming a cavity with an edge portion extending along the length of said enclosure, said enclosure having opposite edge portions, said enclosure further having a cavity downwardly facing surface;
- means on said enclosure and said edge portion forming inlets between said enclosure and said floor for sludge and liquid in said reservoir to flow into said cavity;
- a source of pressurized gas;
- gas emitters connected to said source of pressurized gas extending along the length of said edge portion operable to emit gas into said cavity of said enclosure drawing liquid and sludge via said inlets into said cavity;
- an outlet leading from said cavity for liquid and sludge to flow out of said enclosure;
- an upwardly extending tube connected to said outlet and extending to external of the reservoir;
- and,
- a flow direction device positioned within said cavity between said edge portions directing the liquid and sludge upwardly within said cavity;
- said flow direction device having an upwardly facing surface opposed to said cavity downwardly facing surface defining a channel through which liquid and sludge from said inlets flow;
- and,
- a booster gas emitter connected to said source of pressurized gas, said emitter located atop said flow direction device emitting gas to assist flow of liquid and sludge from said channel toward said second end and said outlet.
