PURPOSE:To provide the titled dust collecting apparatus of which the machine material is brought to long life and easily regenerated, constituted of such a mechanism that a part of the floating substance in the revolving fluid in a dust removing chamber is caught by a barrier plate and the remainder is filtered by the filter material of a rotary cylinder while the flexible filter material is floated by the reverse rotation of the cylinder to clean the same. CONSTITUTION:The fluid to be purified sucked by a suction fan 13 is flowed into a dust removing chamber 1 from a suction port 14 in a revolving state and the relatively heavy floated substance therein is centrifugally caught by a barrier plate 15. The remaining floating substance is filtered by the filter material 9 and the filtering orifices 8 provided to a rotary cylinder 6. The cleaning of the filtering surface 5 is performed by the floating of the flexible filter material 9 by the reverse air stream generated by the reverse rotation of the cylinder 6. Because the relatively heavy floating substance is preliminarily removed to prevent the damage of the filtering surface 5 which is, in turn, cleaned by extremely short-time reverse rotation, the life of the apparatus is extended and is always kept in excellent state.
