VACUUM DUST CLEANER Russian patent published in 2023 - IPC E01H1/08 

FIELD: non-ferrous metallurgy

SUBSTANCE: 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, other production sites, as well as the roadway. Vacuum dust cleaner consists of (1) a vacuum hopper (2) with filters for air purification (11) with a quick cleaning system, a vacuum pump (6) pneumatically connected through a vacuum hopper (2) with the main vacuum nozzle (4) and at least one additional nozzle (5), all of them placed on a self-propelled wheeled chassis. The vacuum hopper (2) contains an additional pipeline (15) on the clean side of the filters (10) with a built-in valve (16), driven by a hydraulic cylinder (21), activated by a hydraulic distributor (31) from the control system, providing the quick filter cleaning system with periodic cleaning of the filters (11) blowing them back with air from the atmosphere due to the vacuum in the hopper (2), by connecting the hopper (2) to the atmosphere.

EFFECT: simplification of the design and the expansion of performance indicators to enable the operation of the machine in electrolysis housings to involve spills of raw materials in the recycling.
