Abstract
The present invention is directed to a drilling fluid reclaimer. The reclaimer has at least one adjustable screen assembly for providing a leveling filter for reclaimed drill fluid. Used drill fluid is placed at the screen assembly at the front the of the screen assembly. The at least one screen is vibrated to separate large particulate matter from liquid drilling fluid. A second screen is provided for additional filtering. Large particulate matter is expelled by a chute at the back of the screen assembly. Drilling fluid passing through the screen is “reclaimed” for use with a drilling system.
Claims21
A system comprising:
- a soft excavation unit, comprising:
- a vacuum system;
- a hollow, elongate body with an open end and a second end in communication with the vacuum system;
- a rotatable bit wholly contained within the body and situated adjacent the open end;
- a supply of fluid in communication with the rotatable bit;
- in which a first fluid pathway interconnects the supply of fluid and the rotatable bit;
- and
- in which a second fluid pathway interconnects the open end of the body and the second end of the body;
- and
- a chamber comprising an inlet port, in which the second fluid pathway terminates at the inlet port;
- a screen assembly situated outside the chamber, positioned to receive material that exits the chamber;
- and
- a mechanical flow regulator disposed between the chamber and the screen assembly.
A system comprising:
- a supply of fluid;
- and
- an integrally formed soft excavation system, comprising:
- an elongate body having an open end;
- a rotatable bit wholly contained within the elongate body and situated adjacent the open end;
- a supply pathway that interconnects the supply of fluid and the rotatable bit;
- a disposal pathway having an inlet end at the open end of the elongate body and an opposed discharge end;
- and
- a vacuum system configured to generate a vacuum pressure within the elongate body;
- in which the rotatable bit and elongate body are formed as a single unit.
A system comprising:

- a rotatable bit wholly contained within the elongate body and situated adjacent the open end;
- a supply pathway that interconnects the supply of fluid and the rotatable bit;
- a disposal pathway having an inlet end at the open end of the elongate body and an opposed discharge end;
- and
- a vacuum system configured to generate a vacuum pressure within the elongate body;
- and
- a reclamation system, comprising:
- a vacuum pressure chamber having an inlet port in communication with the discharge end of the disposal pathway;
- and
- a screen assembly situated outside the chamber, positioned to receive material that exits the vacuum pressure chamber and which produces separate streams of predominantly solid and predominantly liquid material.
