Abstract: A filtering system that includes a cleaning assembly and a filter element in the form of a plate with a plurality of long, narrow through openings or slits in each of a plurality of rows. The cleaning assembly includes a slit-cleaning system connected downstream of the filter element to clean each slit. The cleaning assembly may also include a scraper cleaning system positioned upstream of the filter element. As fluid enters the filtering system, the debris or trash is filtered from the fluid and deposited on the upstream surface of the filter element and in the slits for removal by the cleaning assembly.

Abstract: A pair of cylindrical composite rollers formed of a metallic drum having a thick outer elastomeric layer are mounted transversely in a rectangular frame of a drilling mud separation unit over which a wide endless-loop chain-link belt is driven in a continuous loop moving along the longitudinal axis of the frame. The drive roller has a plurality of axially spaced circumferential rows of radially extending teeth that are machined in the surface of the elastomeric material. The endless belt is formed of a plurality of laterally adjacent jointed links hinged together by transverse rods. As drilling mud or drilling fluids are conducted onto the moving belt, liquids and particles smaller than the openings in the belt pass through the openings and liquids and particles larger than the openings are transported on the moving belt and are discharged off of one end as the belt completes its path. The teeth of the drive roller are sized and spaced to receive and engage the plurality of laterally adjacent jointed links of the wide belt and are of sufficient length to protrude slightly beyond the outer surface of the links as they pass around the front drive roller to dislodge gumbo and other large solids which may otherwise stick in the openings of the links and clog the belt. The elastomeric roller surfaces and teeth reduce wear and prevent metal-to-metal contact and sparking.

Abstract: A continuous-belt drilling mud separation unit is removably mounted in a box-like housing disposed in the flow path of drilling mud or drilling fluids and is operated by a motor on the housing. The separation unit includes a generally rectangular frame, a tensioning system, and a wide continuous belt in the form of a mesh screen, chain, self-cleaning chain link belt, or combination chain link belt and wire mesh screen which extends around rollers or sprockets and is driven in a continuous loop moving along the longitudinal axis of the frame. As drilling mud or drilling fluids are conducted onto the moving belt, liquids and particles smaller than the openings in the belt pass through the openings and liquids and particles larger than the openings are transported on the moving belt and are discharged off of one end as the belt completes its path. The drilling mud separation system is installed upstream from conventional solids control equipment, such as shale shakers, and removes large amounts of large drill solids and gumbo from the drilling mud or drilling fluid prior to the drilling fluid or drill mud flowing to the conventional solids control equipment. By removing large drill solids and gumbo from the drilling mud or drilling fluid, the present apparatus improves the efficiency and performance and reduces the cost of operating and maintaining the conventional solids control equipment.

Abstract: The invention relates to a device for receiving and separating chips created by machine-tools and coolant, the coolant being redirected in order to be reused and the chips being carried away. The inventive device comprises: a receiving tank (1) for receiving the chips and the coolant; a rising guiding section (3) which is connected to the receiving tank (1); a raised output section (4) connected to the guiding section (3); a chain-type, closed transport element which is guided at least into the region receiving the chips and the coolant, and into the output section (4), by means of deviation elements (6, 7), at least one of said deviation elements being coupled to a rotating drive; and a rotatably mounted filter drum (12) which is connected to the transport element in a driven manner. The aim of the invention is to provide a solution which enables the bearing load of the filter drum to be reduced in one such device, and to enable a filter cake to be formed on the outer side of the circumference of the drum in spite of the continuously rotating transport element, said filter cake positively influencing the filter action. To this end, the transport element is guided on guiding rails (13) along the filter drum (12), at a radial distance therefrom, and interspaced co-operating driving elements are provided on the transport element and on the filter drum (12), said driving elements only acting on the filter drum (12) in the circumferential direction.

Abstract: A bypass diverter 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 verter plate, upper and lower baffle plates and a grate 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 bypass diverter box baffle plates, diverter plate and grate, and selective utilization of the mud separation unit removes large amounts of gumbo, heavy clays and drill solids from the drilling mud and allows high flow rates to be easily processed by shale shakers and other conventional downstream solids control equipment of the mud system and compliments the drilling operations with respect to changes in the lithology, geological formations, or loss of returns in relation to the gallons pumped or folume of drilling fluid or drilling mud entering the bypass diverter box.
