  • Patent number: 8257585
    Abstract: A debris catcher uses induced circulation from a venturi to urge debris laden flow into the lower end of a housing. An inlet tube maintains velocity so as to keep the debris moving with the fluid stream as it goes up the inlet tube. A screen fits over the open end of the inlet tube and runs down around the inlet tube toward the entrance of the debris laden fluid into the lower end of the housing. There is a clearance around the cylindrical portion of the screen so some flow can exit that way. There is also an open exit through the top of the screen that can be reached after the fluid stream makes two hairpin turns. Many modules can be stacked. Each module has a large screen area for flow to exit and progressive modules can have smaller screen openings in an uphole flow direction.

    Abstract: A filter cartridge which removes particulate contaminants from liquids includes an annular filter element which, for example, may be a pleated paper filter element, as well as an array of fins which impart a spiral motion to the liquid prior to the liquid passing through the filter element. The spiral motion imparts a centrifugal force to the particulate contaminants causing heavier filter contaminants to move away from the filter media to proximity with the wall of a housing enclosing the filter media and to subsequently accumulate in an axial space disposed beneath the filter media. Since the filter media does not need to remove particles already precipitated out of the liquid, the life of the filter media is extended, the capacity of the filter media is increased, and the distribution of contaminant particles over the upstream side of the filter media is made more uniform.

  • Patent number: 5234589
    Abstract: A filter assembly for filtering contaminants from liquid. A housing has a filtering chamber and an inlet port and an outlet port communicating with the chamber for flow of liquid therethrough. Filter media is located in the filtering chamber for filtering contaminants from liquid flowing through the filter media to the outlet port. A sump region is provided in the filtering chamber at the bottom thereof below the inlet port. Contaminants in the liquid entering the chamber from the inlet port tend to gravitate toward the sump region for collection. A separator member is located in the filtering chamber below the inlet port. This separator member substantially separates the filter media and sump region, and gravitating contaminants gravitate from the inlet port to the separator member. The separator member provides for communication of the gravitated contaminants into the sump region but tends to trap those contaminants in the sump region.

  • Patent number: 4840732
    Abstract: The fuel cleaning system of the present invention includes removal of water and sludge which is accomplished using a gravity separator with a mist extracting means utilizing a large commercial cartridge type filter. The filter removes particles larger than 20 microns plus any water that was not removed in the gravity separator. Clean fuel from the filter is discharged at the bottom of the fuel tank at high velocity through a small opening. This agitates the water and sludge. The suction side of the system is located approximately one inch above the high velocity discharge where it picks up the water and sludge for removal by the separator and filter sections. During the process, water and sludge are drained from the separator and filter as accummulated. The system is powered by an explosion-proof electric motor driving a pump which handles approximately 5 gallons per minute.

  • Patent number: 4780203
    Abstract: A separator for removing water from a lower density liquid fuel has a generally circular cross-section container with co-axual downwardly open outlet conduit that includes a portion widening towards the bottom entry opening. An inlet above the widening portion of the conduit directs a liquid flow obliquely downwards and radially offset from the conduit to generate a rotational flow promoting separation of the denser water fraction from the fuel. Smaller water droplets that drift down the outer surface of the outlet conduit because they are less influenced by centrifugal forces, are collected in an upturned lip at the bottom edge of the conduit. There they coalesce into larger drops that can fall through the outlet flow to the bottom of the container. A shield in the container lower region limits the entrainment of remaining smaller droplets from that lower region into the outlet flow.
