摘要:
A belt filter apparatus for treating material to separate solid and liquid components comprises an endless belt structure adapted to circulate around a path incorporating guide roller structures around which the belt structure passes. The endless belt structure comprises an elongate belt portion of water permeable material, and has two opposed longitudinal edges. A zipper releasably connects the two longitudinal edges together to form a tubular structure with a flexible sidewall. The circulating path includes an assembly zone where the longitudinal edges are brought together and connected by the zipper to form the tubular structure, and a disassembly zone at which the zipper is released to separate the longitudinal edges and open the tubular structure. Means are provided for compressing a portion of the tubular structure to express liquid from the material contained in the tubular structure. The liquid discharges from the tubular structure through the water permeable belt portion.

Described is a continuous loop filter media and a method of filtering particulate, such as metal, from a liquid media comprising supplying a filter media 12 of a type supported in a flow passage which is used to filter particulate 56 from the liquid; wherein the filter media is comprised of at least two fabrics, a first top fabric 62 comprised of non-woven synthetic fibers 80 and a second bottom fabric 60 comprised of yarn pre-designed into a shaped porous support layer, such as, woven fibers 84, 86, 88, the first and second fabrics lying substantially on top of each other and bound together 62, 64, 66, 74 to form a continuous loop filter media; passing the continuous loop filter media into a first stage comprised of liquid and waste particulate and filtering at least a portion of the particulate therefrom onto the continuous loop filter media; passing the continuous loop filter media with the filtered particulate thereon to a removal stage 52 wherein at least a portion of the filtered particulate is separated from the continuous loop filter media; and passing the continuous loop filter media back to the first stage.

A weir box disposed upstream from conventional solids control equipment of a mud system of a drilling rig contains a drilling mud separation unit having a continuous-loop scalper screen that is driven in a continuous loop to separate, convey and discharge large amounts of gumbo, heavy clays and drill solids at the end of the separation unit. The flow divider box is a box-like housing with a diverter plate, weir baffle plates and a sliding gate that allows drilling fluid or drilling mud to be selectively directed to the mud separation unit to be separated prior to passing to the conventional downstream solids control equipment or allows the fluid to bypass the separation unit and flow directly to the conventional solids control equipment. The sliding gate is adjustable to selectively control or meter the flow rate and to create a hydrostatic head upstream from the conventional solids control equipment. The weir box baffle plates, sliding gate, and selective utilization of the mud separation unit allows the operator to produce an increased hydrostatic head, which enables high flow rates to be easily processed by shale shakers and other conventional downstream solids control equipment of the mud system and to compliment the drilling operation with respect to changes in the lithology, geological formations, or loss of returns in relation to the gallons pumped or volume of drilling fluid or drilling mud entering the weir box.

An auxiliary oil filtration system and method for filtering oil in an engine is provided. The auxiliary oil filtration system consists of an auxiliary filtration device, an integral oil transfer pump controlled by an electric motor and that is in electrical communication with an electrical control unit, an electronic pressure sensor, fluid conductors, and means for connecting hardware. The auxiliary filtration device is separate from the primary engine lubrication system, and includes a media supply reel having a roll of filtering media thereon which is moveable to a take-up reel. A media indexing system advances the media supply reel as the filtering media becomes plugged. An electronic pressure sensor dictates the advancement of the filtering media when a pre-determined differential pressure across the filtering media is attained. When all of the filtering media has been transferred from the supply reel to the take-up reel, the cartridge is replaced.

According to a waste water treatment method and apparatus of the present invention, a permeable sheet 3 is fed into a treatment tank 2 in which a stream is formed. The waste water, which flows downstream, is caused to pass through the permeable sheet 3, while the permeable sheet 3 travels in the treatment tank 2 so as to traverse the surface of the waste water on a downstream side in the flowing direction of the waste water. Therefore, not only the sludge in the waste water but also the oily substances floating in the waste water can be collected and removed because they cling to the permeable sheet 3 and are gathered by it. As a result, a waste water treatment tank 2 and the like can be maintained in a usable state for a long time. In addition, there can be obtained a treated water to which microbial treatment can be applied.

The invention relates to a fastening element for two-dimensional fibre material comprising a basic element and pin-shaped profile elements, which protrude from the basic element in order to penetrate the fibre material. Provision is made for the profile elements to be deformable in order to form retaining heads for the fibre material. The invention further relates to a method for fastening two-dimensional fibre material which can be carried out with a fastening element of such type. By the method in accordance with the invention a cold micro-riveting can be achieved.

A connector arrangement for connecting web ends (5), in particular an endless filter web, comprises two elongate elements which each have at least one elongate leg (1, 2) for fastening on one of the web ends (5), and a longitudinal flank (9) directed away from the web end (5). In a first longitudinal-section plane the longitudinal flank (9) has a first periodic contour, which engages in a corresponding contour of the other element respectively. In a second and third cross-section plane extending parallel to the first longitudinal-section plane, the elements each have second and third periodic contours (10, 11), which engage in a form-fitting manner in respectively corresponding contours (10, 11) of the other element respectively. The first to third contours form a groove (13, 13′) and a tongue (12) in at least one cross-section plane.
