Abstract

FIELD: dust-catching devices, in particular, cleaning of gas delivered into atmosphere and recuperation of ink powder not settled on product. SUBSTANCE: cyclone has casing 1 with perforated lower part 2 located in hopper 3, inlet pipe 4, discharge opening 5 and exhaust pipe 6. Cyclone is further provided with auxiliary hopper 7 having perforated lower part 8 and mounted within main hopper 3. Auxiliary hopper 7 has additional dividing wall 10. Such construction allows effective catching of powder to be provided due to reduced entrainment and carrying powder away from hopper by inner helical flow. Space between walls is communicated with suction system 12 through filter 11 mounted in annular chamber 13 and is separated from filter 11 by perforated divider 14. EFFECT: increased efficiency, simplified construction, wider operational capabilities and enhanced reliability in operation. 2 cl, 1 dwg

Claims (1)

The invention relates to dust collecting devices and is intended for the purification of gas released into the atmosphere and the recovery of powder paint that has not settled on the product. The cyclone contains a housing 1 with a perforated lower part 2 located in the hopper 3, an inlet 4, a discharge opening 5 and an exhaust pipe 6. To increase the efficiency of powder capture by reducing its entrainment from the hopper by an internal spiral flow, the cyclone is equipped with an additional hopper 7 with a perforated bottom part 8, located inside the main hopper 3, which is equipped with an additional wall 10. The interwall space is connected through a filter 11, located in an annular chamber 13, with a suction system 12 and about separated from the filter 11 by a divider-perforated partition 14.
