PURPOSE: A venturi nozzle and a filter structural body for dust collector are provided to increase dedusting capacity which takes off dust accumulated on a filter surface by improving venturi nozzle structure and to minimize intake resistance by widening an inhaling area. CONSTITUTION: A venturi nozzle (100) comprises a venturi cone, a dispersion wing part, and a lower housing. The venturi cone has a streamline shape in which the diameter gets bigger from the upper end to lower direction. The lower edge of the venturi cone is opened and forms a space with a predetermined depth. The dispersion wing part comprises a cylinder pipe which is inserted and united to the outer edge of lower venturi cone through the penetrated center part and a plurality of wing parts which is protruded in vertical direction along peripheral of the cylinder pipe with a predetermined interval. The lower housing forms a curved surface on one side and is screw-coupled on the other side by being inserted to the venturi cone through the lower end. |
