Slidbestandig separationsindretning til fraseparering af sand- og stenpartikler

摘要

A separating device for removing sand and rock particles, and is an integral component of extraction equipment for extraction of liquids or gases from deep wells, having at least one ceramic filter module comprising: an annular stack of annular discs, the upper side of which has at least three elevations uniformly distributed over the circumference of the discs, the discs are stacked such that a separating gap for the removal of sand and rock particles is present between the individual discs, a coupling-on element at the upper end and a coupling-on element at the lower end of the annular stack, a clamping device bracing the annular stack, an outer cage, a coupling element at the upper end and a coupling element at the lower end of the filter module connecting the filter module to further components of the extraction equipment.
