FIELD: technological processes.
SUBSTANCE: invention relates to cleaning of pipes from internal deposits. Proposed device comprises housing mechanically coupled with motor stator, input gear shaft mechanically coupled with motor rotor. Housing consists of two cylindrical discs, coaxially installed by means of bearings external hollow output shaft, internal teeth of which are located between housing discs. Housing discs are interconnected by shafts with satellites built in them with possibility of interaction by means of gear transmissions with input gear shaft and hollow output shaft. To the end of the gear input shaft the disk shaft is fixed, the diameter of which corresponds to the diameter of the external hollow output shaft. External hollow output shaft and the disk shaft on the peripheral surfaces contain grooves with opposite helical wraps with masseurs with built-in brushes or scrapers installed in them.
EFFECT: higher efficiency of cleaning due to optimization of movement of cleaning elements.
