VACUUM DUST CLEANER Russian patent published in 2022 - IPC E01H1/08 B08B5/04 C25C3/00 

FIELD: non-ferrous metallurgy.

SUBSTANCE: invention relates to the field of non-ferrous metallurgy, and in particular to self-propelled industrial machines for vacuum cleaning of dry spills and fine dust in electrolysis cells for the production of aluminum by the electrolytic method, workshops, warehouses and other production sites. The vacuum dust harvester consists of a self-propelled wheeled chassis (1) containing a power plant (4), a driver's cab (2) installed in the front of the chassis (1), a vacuum hopper (3) installed behind the driver's cab (2) and pneumatically connected with the main nozzle (5) and at least one additional nozzle. The power plant (4) is located longitudinally in the front of the chassis (1), to the side of the cab (2), on the rear of the chassis (1) there is a vacuum hose (7) made removable, and the vacuum hopper (3) is made with the possibility of tilting in front back, and the lower part of its rear wall (8) is made with the possibility of opening.

EFFECT: increasing the productivity of the machine by reducing the time for unloading the vacuum hopper and improving the stability of the machine by lowering the center of gravity in height and reducing the overall height of the machine.
