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.

Embodiments of a shale shaker filtration system of the present invention generally include a filtration component, a positioning component, and a frame, wherein the filtration component includes at least one screen having one or more layers of a sieving material, the positioning component includes one or more first connecting members and one or more second connecting members, and the frame is sub-divided into a plurality of units having openings; and wherein each positioning component is disposed at least partially within a frame unit opening and is reversibly engaged with the frame via the second connecting member(s), and each filtration component is disposed on top of a positioning component and is reversibly engaged therewith via the first connecting member(s). Embodiments of a method of filtering solid materials from a liquid utilizing embodiments of a shale shaker filtration system of the present invention are also provided.

A flow back system for separating solids from a slurry recovered from a hydrocarbon well. The system includes a V-shaped tank with a first series of baffles configured to cause the settling of solids that are moved by a shaftless auger to a conduit fluidly connected to hydrocyclones mounted over a linear shaker. The overflow from the hydrocyclones is discharged through a second conduit back into the tank for processing by a second series of baffles resulting in a clean effluent. The clean effluent is recirculated in the well.

A combined hopper and shaker assembly which can be used at least in processing excavation or other remains. The assembly features a hopper that can be pivoted (through operation of a hoist/sling) to cause the contents of the hopper to be fed via gravity through an exit chute onto the shaker. The hopper includes splash guards or sidewalls on the portions thereof that are proximate the pivot axis and an internal shape along the exit chute so as to guide the contents of the hopper toward the exit chute.

An aggregate processing system, including a water source, and a vibrating screen device including a plurality of spray nozzles disposed above a screen for spraying wash water onto aggregate during aggregate processing. A strainer device is provided for removing particulate debris from a water wash stream flowing from a water source to the spray nozzles, the strainer device including a filter screen having an angled shape with a convex side facing the strainer inlet and fluid flow path. The strainer is configured to induce turbulent flow for separation of the particulates by gravity, with the filter screen blocking particulates above a given size. In this manner, particulates which may otherwise lead to clogging of the spray nozzles are removed from the wash water stream.

A screen assembly for use in vibratory separators, e.g., shale shakers. The screen assembly has a support with first and second sides, and support surfaces bounded by and connected to at least a portion of the first and second sides. Overlying and adhered to at least portions of the support surfaces is a screen which has alternating planar and undulating portions of screening material.

An apparatus, system and method have a rod attached to and extending across a screen to engage with a receptacle. A box is positioned beneath the filtration screen. An air bag is activated to inflate the filtration screen to compress against a plate. A junction extends from the plate, and the air bag rises to move the junction toward the receptacle to compress the rod against the receptacle to hold the rod. The filtration screen may be constructed from mesh material sized to permit materials to flow through the filtration screen. A vibratory element in the box vibrates to assist filtration.

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.

Monitoring drill cuttings suspended within a drilling fluid with one or more cuttings detection devices as the drill cuttings traverse one or more shaker screens of a shaker. Drill cuttings data of the drill cuttings is then generated with the one or more cuttings detection devices. Analyzing and processing the drill cuttings data with one or more processors included in a data acquisition system and thereby generating processed drill cuttings data. The processed drill cuttings data is indicative of at least one of a cuttings size distribution and a density of the drill cuttings. One or more operational parameters of the shaker may then be modified based on the processed drill cuttings data.

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.
