Abstract:
A screen panel for a vibratory machine includes a polymer layer comprising a resilient material and defining a plurality of panel apertures extending through the polymer layer from an upper screening surface to a bottom surface of the polymer layer, each of the plurality of panel apertures defining an aperture perimeter. The screen panel includes a reinforcing structure having a top surface that supports at least a portion of the bottom surface of the polymer layer, wherein the reinforcing structure is positioned under the polymer layer along only a portion of the aperture perimeter of each of the plurality of panel apertures.
Abstract:
A screening apparatus includes elongate beams and screen panels mounted to the beams to form a broad screening surface. Each of the panels are mounted so that side edges of adjacent panels are in facing relationship. Each panel is mounted to a pair of beams to bridge between two adjacent beams. The panels are mounted to the beams by fixing members. The fixing members have a pair of upstanding rails that are spaced apart to define a longitudinal gap between them. The panels are mounted to the beams by cooperation between the side edges with a rail of a fixing member. Cover strips extend along the beams and include a cover portion and a locking portion. The cover portion bears against an upper surface of a pair of adjacent panels and the locking portion bears against facing surfaces of the rails to resist movement of the rails towards each other.
Abstract:
A screen system for improving a vibrating shaker apparatus for separating drilling fluid and drill cuttings is described. The screen system comprises a dual screen having a coarse mesh upper screen attached to a finer mesh lower screen with a channel between the two screens. One or both of the screens may be wedge shaped to affect the flow rate of drilling fluid and drill cuttings across the screen. The screen systems can be installed in existing shaker apparatuses using various attachment systems, such as wedge clamping systems, hydraulic or air pressure clamping systems, or hook screen systems.
Abstract:
An apparatus, a system and a method for reinforcing a screen has a screen rod assembly extending from a first end to a second end. The screen rod assembly encloses an interior. A spring-loaded plunger is located in the interior and adjusts the length of the screen rod assembly. A ball joint is on the screen rod and defines sections of the screen rod assembly that bend around the ball joint to reduce the length of the screen rod. A sleeve extends from a screen with segments separated by a fold line extending along a width of the screen. The sleeve receives the screen rod assembly to reinforce the screen. In an embodiment, a screen pinch assembly is defined where the sleeve engages a retention clasp of a screen tensioning system that receives the screen. The screen pinch assembly holds the screen in place.
Abstract:
A system includes a first screen having a first latch on a first end of the first screen, a second screen having a first catch on a first end of the second screen, and a screen adapter that connects the first screen and the second screen. The screen adapter includes an elongate body, a first catch formed on a first side of the elongate body that engages the first latch on the first end of the first screen, and a first latch formed on a second side of the elongate body that engages the first catch on the first end of the second screen. A method includes inserting a first screen into a vibratory separator, inserting a screen adapter into the vibratory separator, coupling the screen adapter to the first screen, inserting a second screen into the vibratory separator, and coupling the second screen to the screen adapter.
Abstract:
A screen system having a plurality of screen elements that can be readily removed and replaced to vary one or more characteristics of the screen surface formed by the screen system. The screen system includes a support system for supporting at least one screen element to prevent deformation of the screen element that typically would occur due to the insufficient structural stability of the at least one screen element relative to the weight of the product being screened. Preferably, the support system includes one or more support elements that can be readily and easily installed and removed from the screen system. The support system is preferably configured to permit the one or more support elements to be positioned at different locations in the screen system. Preferably, the support system is configured to permit a variety of different support elements to be used to allow a greater variety of screen elements to be used.
Abstract:
A screening machine includes wall members, screen assembly guide members, a screen assembly and a compression assembly. The screen assembly includes a frame with a plurality of side members and a screen supported by the frame. The compression assembly is attached to at least one wall member and forms the screen assembly into a concave shape.
Abstract:
A fixing arrangement (10) for a screen panel comprising at least a screen panel(11) having side edges/side faces(4,7) on either side. The panel is adapted to be fixed to an adapter bar(1) and said bar(1) is adapted to be mounted on a screen deck frame. This bar(1) extends horizontally over said screen deck frame and between side edge regions of a pair of said screen panels(11), said adapter bar has at least a female portion in the form of a fixing groove (5) on its top surface(21) such that said groove(5) has an internal profile that exactly matches the outer profile of the bottom part(3) of said screen panel(11) for receiving said bottom part(3) securedly and snap fitting therewith and said adapter bar(1) is fixed on a portion(2) of said screen deck frame by suitable fixing means.
Abstract:
A removable, magnetically-affixed mechanical wear element, preferably comprising ultra-high molecular weight polyethylene or polyurethane materials, is provided for affixation to a ferrous substrate material. The mechanical wear element is configured so that the magnetic attachment element is not easily removed or dislodged from the mechanical wear element, without regard to choice of mechanical wear element material utilized.
Abstract:
A locking twist pin screen panel retainer system utilizes a plurality of twist pins, each with a mushroom-shaped screen panel engaging head. Each one of the locking twist pins is positionable in a deformable receiver which is attachable to a support tube or bottom rail of a vibrating separatory machine. Insertion of the individual twist pins each into a cooperating one of the retainers, and the subsequent rotation of each twist pin through 90°, both secures the pin in the cooperating receiver and also secures the receiver in place on the underlying support tube or rail of the vibrating separatory machine. Removal of the pins and their receivers, if necessary, is accomplished by a further rotation of each pin through another 90°.
