  • Patent number: 8833447
    Abstract: The invention relates to a separating device for tubular flow-through devices (22) which serve for the extraction of liquids or gases from wells drilled in rock or deep wells, the separating device being suitable for the removal of sand and rock particles and comprising an annular stack (20) of brittle-hard annular disks, the disks (30) being stacked and braced in such a way that a separating gap (37) for the removal of sand and rock particles is present in each case between the individual disks (30), a coupling-on element (18, 19) at one or both ends of the annular stack (20), a clamping device at one or both ends of the annular stack (20), making it possible on the one hand to flexibly brace the brittle-hard disks (30) and on the other hand to variably fasten the annular stack (20) on the tubular flow-through device (22).
