DEVICE FOR CLEANING BOTTOM SURFACES USING COMPRESSED AIR ENERGY Russian patent published in 2024 - IPC B08B5/04 

FIELD: shipbuilding.

SUBSTANCE: invention relates to shipbuilding and can be used for cleaning bottom surfaces of water bodies from sedimentary finely dispersed contaminants. Device for cleaning bottom surfaces of water bodies from sedimentary finely dispersed contaminants uses exclusively compressed air energy for rotation of a conical rotor fixed on the shaft, on which spiral projections are located and which is placed in a conical stator with a smooth inner surface, wherein the stator and the rotor are made in the form of truncated cones, on the side of the smaller base of the conical rotor there is a compressed air supply unit, which is equipped with nozzles made with possibility of creating finely dispersed foam from compressed air and water, and its supply into the space between the stator and the rotor, in addition, between the nozzles there is an open space for free movement of bottom liquids, which are sucked into the gap between the rotor and the stator and from there removed from the device.

EFFECT: simplification of device for cleaning of bottom surfaces, and consequently, increasing of efficiency and simplification of its maintenance.
