INDUSTRIAL VACUUM CLEANER Russian patent published in 2023 - IPC A47L5/00 

FIELD: industrial cleaning equipment.

SUBSTANCE: invention relates to the field of harvesting equipment, in particular to mobile dust extraction devices, and can be used for cleaning and collecting various contaminants in industrial premises. An industrial vacuum cleaner contains a wheel frame 1, communicating with the intake nozzle 2, connected in series by air ducts 3, 4, 5 and technologically interconnected centrifugal dust separator for pre-cleaning, a dust separator for post-cleaning 6 containing a fine filter 7, a blower device in the form of a vortex blower 8. The centrifugal dust separator is an outer housing 10 connected to a removable dust collector 9 with a lower tangential inlet pipe 11 and an exhaust pipe 12, covered by a screw centrifugal channel 14 having a conical shell 13, made with outlet windows 15 and an upper inlet window 16. Inside the removable dust collector 9 there is a dust collector of small particles 17. The outer housing 10 is made cone-shaped. The tangential inlet pipe 11 is connected to the intake nozzle 2 through the suction hose 18.

EFFECT: simplification of the design, an improvement in the quality of cleaning and operational reliability, an improvement in operational properties, as well as an expansion of the arsenal of technical means for this purpose.
