20220088639 · 2022-03-24 ·

Embodiments of the present disclosure include a screen basket apparatus includes a substantially vertical cylindrical frame and a synthetic screening surface secured to the frame. The synthetic screening surface may be configured to separate carbon or resin from a slurry of a carbon-in-leach, carbon-in-pulp, resin-in-leach, or resin-in-pulp material as fluid flows from outside to inside the screen basket apparatus such that carbon or resin is retained on an external surface of the synthetic screening surface. The cylindrical frame may be a grid frame and the synthetic screening surface may include a plurality of replaceable screen assemblies attached to the grid frame. The grid frame may include a plurality of openings and each of the plurality of openings is configured to receive a respective one of the plurality of replaceable screen assemblies. The synthetic screening surface may include injected molded thermoplastics, thermoset polyurethanes, and/or other polymeric materials.

System for separating solids from a fluid stream
11219845 · 2022-01-11 · ·

A system for separating solids from a fluid includes a containment vessel having a V-shaped tank in fluid communication with an agitated overflow tank. Baffles within the V-shaped tank provide a series of zones where the fluid is deposited for processing. A shaftless auger at the bottom of the V-shaped tank transfers solids to an area where they are pumped to a first hydrocyclone assembly associated with a first shaker. Overflow from the hydrocyclone assembly and underflow from the first shaker is further processed by a second hydrocyclone assembly associated with a second shaker. Overflow from the second hydrocyclone assembly and underflow from the second shaker are deposited into overflow tank which contains the cleaned fluid.

VIBRATING PAINT STRAINER STAND
20220008847 · 2022-01-13 ·

A system and method for a vibrating paint strainer stand that enables the user to effectuate the flow of paint through a paint strainer by vibration whereby the paint strainer is positioned in a paint strainer holder on the stand such that one or more vibration motors attached on a neck opposite of the holder can provide vibration to the paint strainer.

Hydro excavation vacuum apparatus that process spoil material onboard the apparatus by separating water from the cut earthen material are disclosed.

Drilling fluid reclaimer

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.

Screening apparatus

A shale shaker includes a basket having a front, solids discharge end and a rear, feed end spaced apart by opposed first and second sides. The basket includes a lower, first, screen deck and an upper, second, screen deck directly above the first screen deck. The screening surfaces of the screen decks are spaced apart, by a vertical spacing of from 20 mm to 250 mm. There is a cavity above the feed receiving end of the first screen deck, in direct fluid communication with the space between the screening surfaces of the first and second screen decks ( ) that only receives feed that has passed through the upper, second, screen deck. The cavity extends to higher than the extreme end of the screening surface of the second screen deck, at its feed receiving end.

Gas tight shale shaker for enhanced drilling fluid recovery and drilled solids washing
11111743 · 2021-09-07 · ·

A gas tight shale shaker for enhanced drilling fluid recovery and drilled solids washing. A process and apparatus for liquid phase-solid phase separation of oil base drilling mud-containing drill cuttings is described including flowing the drilling mud-containing drill cuttings over a vibrating screen bed to cause a least a portion of the drilling mud to pass through the screen bed and the drill cuttings to remain on the screen bed. A diluent is added to the oil base drilling mud containing drill cuttings prior to flowing the drilling mud containing drill cutting over the screen bed. The entire process is performed in a gas-tight environment preventing escape of diluent from the process into the external atmosphere and preventing introduction of gases into the process from the external atmosphere.

Sieving apparatus and method of using same
11065646 · 2021-07-20 · ·

This invention relates to a sieving apparatus and method for separating solid particles above a predetermined size from a fluid by carrying the solids-containing fluid across at least one sieving cloth in a frame connected to a shaking device for providing shaking motion. The sieving apparatus includes an inlet portion for receiving solids-containing fluid, a discharge portion for solids that have been carried across the at least one sieving cloth and an outlet portion for fluid that has passed through the sieving cloth. The sieving apparatus further includes at least one endless sieving cloth arranged for rotating around at least two spaced-apart turning-rollers, at least one being connected to a motor, and a pumping device in fluid communication with a suction nozzle located proximate an underside of the endless sieving cloth between two of the turning-rollers, to produce a fluid flow through at least a portion of the endless sieving cloth.

Separating drilling cuttings and gas using a liquid seal

A gas separator, gas separation system, and method for separating gas from drilling cuttings by actively maintaining a liquid seal of liquid in a lower portion of a separation vessel by controlling an introduced amount of the liquid admitted to the separation vessel as a removed amount of the liquid is removed from the separation vessel and by promoting agitation of the drilling cuttings in the liquid in an agitation chamber within the lower portion of the separation vessel to aid removal of the drilling cuttings along with the removed amount of the liquid.
