FIELD: metallurgy.
SUBSTANCE: dust extractor includes cylinder-taper casing with branches for supply of powder-gas mixture, withdrawal of treated gas and discharge of dust, electromagnetic dust collection system, spiral guide of powder-gas mixture movement, cellular core, locking sleeve and rests, installed between barrel and cellular core. Dust extractor is implemented of top cylinder-taper butt with flange and branch for withdrawal of treated gas, dust catching unit with flanges and with branch for supply of powder-gas mixture and bottom cylinder-taper butt with flange and branch for dust withdrawal. Dust catching unit is assembled on separate stand in composition of cylinder with flanges and branches for supply of powder-gas mixture. On it on the outside it is installed electromagnetic system with magnetic conductors, inside there are installed spiral guide for movement of powder-gas mixture, rest of cellular core made of nonferromagnetic material, cellular core in the form of vertical strips made of ferromagnetic material, installed on-the-mitre to movement of powder-gas mixture, and locking sleeve.
EFFECT: effectiveness increase of dust collecting and simplification of equipment mounting.
