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.

Vibratory screening machines that include stacked screening deck assemblies are provided. In some embodiments, at least one of the vibratory screening machines may include an outer frame, an inner frame connected to the outer frame, and a vibratory motor assembly secured to the inner frame for vibrating the inner frame. A plurality of screen deck assemblies may be attached to the inner frame in a stacked arrangement, each configured to receive replaceable screen assemblies. The screen assemblies may be secured to respective ones of the plurality of the screen deck assemblies by tensioning the screen assemblies in a direction that a material to be screened flows across the screen assemblies. An undersized material discharge assembly may be configured to receive materials that pass through the screen assemblies, and an oversized material discharge assembly having a deflector may be configured to receive materials that pass over the screen assemblies.

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

A shale shaker for separating formation cuttings from a drilling fluid includes a basket and a screen deck positioned within the basket. The screen deck includes a plurality of screens positioned on a plurality of screen supports, such that each screen is positioned on a corresponding one of the plurality of screen supports. Each screen includes a top side, a bottom side opposite the top side, and a mounting bracket positioned along the bottom side. The mounting bracket includes a pair of parallel first support members and a clamping bar coupled to and extending between the pair of first support members. Each screen support includes a pair of parallel second support members and a latch assembly including a hook assembly positioned between the pair of second support members. The hook assembly is configured to engage with the clamping bar to secure the screen to the screen support.

An apparatus includes a shaker screen onto which downhole materials and fluid from a borehole are to be placed, the downhole materials a product of a downhole operation and a shaker to vibrate the shaker screen to separate the downhole materials from the fluid. The apparatus includes a radar to emit an electromagnetic wave onto the downhole materials on at least one of the shaker screen and a transit and detect a reflection of the electromagnetic wave reflected off at least a portion of the downhole materials and a device to determine a velocity of the downhole materials advancing along at least one of the shaker screen toward a discharge end of the shaker screen and the transit.

A screen assembly for a vibrating shaker is provided. The screen assembly utilizes an elastomeric gasket having a flat profile section and a bulb profile section, wherein said bulb profile section has a hollow interior and is configured so as to form a notched profile section where said bulb profile section connects to said flat profile section.

A separation tank device may include a holding tank having a tank wall coupled to and extending above a tank base. A base wall may be coupled to and may extend above the tank base. The base wall may form a base upper aperture that is opposingly positioned to the tank base, and a base lower aperture may be formed in the base wall. The device may further include a movable wall having a movable upper aperture and a movable lower aperture, and the movable wall may be movable between a first position and a second position. When the movable wall is in the first position, the movable lower aperture may be positioned above and aligned with the base upper aperture, and when the movable wall is in the second position the movable lower aperture may be unaligned with the base upper aperture.

Vibratory screening machines that include stacked screening deck assemblies are provided. In some embodiments, at least one of the vibratory screening machines may include an outer frame, an inner frame connected to the outer frame, and a vibratory motor assembly secured to the inner frame for vibrating the inner frame. A plurality of screen deck assemblies may be attached to the inner frame in a stacked arrangement, each configured to receive replaceable screen assemblies. The screen assemblies may be secured to respective ones of the plurality of the screen deck assemblies by tensioning the screen assemblies in a direction that a material to be screened flows across the screen assemblies. An undersized material discharge assembly may be configured to receive materials that pass through the screen assemblies, and an oversized material discharge assembly having a deflector may be configured to receive materials that pass over the screen assemblies.

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.

A support structure for vibrating screening machine with either a flat screen deck or a crowned screen deck which use a coped and then capped variation of the same prefabricated rectangular tubular cross-member but in rotated orientations. The machine further providing support for a crowned screen media without using a crowned cross-member by providing stringers with differing vertical heights with the centermost stringer having the most height above a flat top cross-member. A plurality of crown straps coupled to a top surface of a cross-member, where the crown straps have a C-shaped portion at one end which has a portion thereof coupled to a top surface of a cross-member.
