GAS OXYGEN CUTTER Russian patent published in 1995 - IPC

FIELD: cutting of ferrous and non-ferrous metals. SUBSTANCE: cutter includes a cutting head and a collector of an air curtain, provided by a filtering chamber with an ejector and by an adsorbent, placed in the filtering chamber. Combustion products of metal and a corrosion-resistant film are being fed for cleaning to the filtering chamber due to creation of vacuum in it by supply of compressed air through a jet, arranged in an expanding packing of the filtering chamber. That provides lowered content of aerosols in a cutting zone. EFFECT: enhanced maintenance due to neutralizing aerosols, being formed at dressing scrap metal with corrosion-resistant coating of combustible materials. 1 cl, 6 dwg
