AXLELESS TURBINE Russian patent published in 2023 - IPC B01D33/00 

FIELD: turbine.

SUBSTANCE: invention related to equipment for air or liquid purification that can be used in axial direct-flow, low-pressure, jet exhaust devices. This device creates pneumo-hydrodynamic resistance in the central part of the impeller neck by placing the impeller blades on the inner surface of the rim. The axleless device has a rigid body (1) and at the same time is the body of an electric motor (2), which drives (rotates) the rotor (3). The rotor has the shape of a tube, inside of which there are blades (4). Blades are attached to the inside of the rotor. The essence of the invention is that the device itself is an electric motor, characterized in that the rotor axis is hollow and blades are located inside it on the walls, the blade shanks are curved relative to the rotor rotation axis.

EFFECT: thus, during operation of the device, the rim with blades creates turbulences of air or liquid and passes them inside the rim, which reduces the contact of dust or small liquid particles with the surface of the blades. Some of the dust or small particles of contaminated liquid are carried away by the flow of air or liquid, and the rest lie in a layer on the blades, then these blades are removed, and dust and dirt are removed from them.
