GRID FOR CYCLONE-TYPE DUST CATCHING DEVICE OF VACUUM CLEANER (VERSIONS)

摘要: FIELD: equipment for cyclone-type cleaner. ^ SUBSTANCE: grid is arranged in upper part of air-discharge channel cyclone casing, where sucked air vortex and contaminants are separated from flow by centrifugal force said flow. Grid adapted preventing sucking into vacuumizer vacuum has casing with set channels, lines continuing axial channels at an acute angle relative to direction, protective screen connected through detachable joint baffling involved According another version, blades on outer periphery predetermined distance one passage spaces between blades, blade profiles direction. Blade space direction condition that adjacent overlap 10-15%, when reflected onto imaginary cylindrical surface axially aligned blades. EFFECT: increased efficiency dust catching decreasing amounts grid. 3 cl, 5 dwg
