Axially eccentrically arranged mixing beam - descaling device for the inner wall of a pipe

摘要

An axially eccentrically arranged mixing beam - descaling device for the inner wall of a metal tube comprises a supporting rod (1), the inside of the metal tube (100) eccentrically or not coaxial with the central axis of the metal tube is arranged and parallel to the center axis of the metal tube, and at least two beam serving for the output of a mixing nozzle units (2, 2 '', 2 "), which along the longitudinal direction of the supporting rod are arranged one behind the other, wherein in each of the nozzle units, at least two mixing jet nozzles (21, 21'', 21") are provided, which along the circumference of the supporting rod arranged uniformly and, starting from the axis of the supporting rod as a center point is emitted in all directions are aligned, wherein the mixed jet nozzles of the nozzle units arranged one behind the other along the circumferential direction of the inner wall of the metal tube to be descaled are arranged offset one behind the other, in order to form mixed jet nozzles matrix and thus to provide an effective descaling region, which the outer surface of the inner wall of the metal tube can cover. With such a descaling device can be a continuous, efficient, stable and environmentally friendly descaling of the inner wall surface of a cold metal pipe can be achieved.
