A kind of biomass powder feeder, comprise drawing-in device and feedway, wherein feedway adopts the reducing motor direct connection to drive screw auger, drawing-in device comprises the barrel that is provided with hopper, it is characterized in that: the cylinder center, the end of barrel is provided with circular hole, set up feeding control apparatus and the coupling tunnel that is provided with the blanking observation window, wherein coupling tunnel is vertical with screw auger, and the bottom of coupling tunnel is communicated with screw auger, the feeding control apparatus comprises the buncher that is installed on the cover plate of barrel top, S. A., the taper blocking cylinder, scraper plate and the supporting disk that is fixed on the coupling tunnel top, wherein the center of supporting disk is provided with bearing carrier ring, supporting disk be positioned at bearing carrier ring around be evenly equipped with material-dropping hole, captive joint with the mouth of buncher in the upper end of S. A., the lower end of S. A. is passed circular hole and is inserted in the bearing carrier ring, the top that S. A. is positioned at circular hole is provided with the taper blocking cylinder, the bottom surface diameter of taper blocking cylinder is greater than Circularhole diameter, S. A. is below the taper blocking cylinder, the place, top at the cylinder end is installed with a plurality of scraper plates, the rotating diameter of scraper plate is slightly less than the barrel diameter, there is certain interval on the base of scraper plate at the bottom of cylinder, the rated output of screw auger is greater than the feeding capacity that enters coupling tunnel from material-dropping hole.
Described biomass powder feeder, scraper plate is 2～5, at the bottom of cylinder, the downward orthogonal projection at the bottom of cylinder of each scraper plate is spiral of Archimedes.
Described biomass powder feeder, the base of scraper plate 3～10mm at the bottom of the cylinder.
Described biomass powder feeder, cover plate is provided with process window, and the sidewall of barrel is provided with the material level observation window.
Its principle of work is: buncher drives taper blocking cylinder and scraper plate rotation, the biomass powder that adds barrel from hopper the barrier effect of taper blocking cylinder drop to circular hole around, again by scraper plate to the center scraping delivery, biomass powder is evenly fallen in the coupling tunnel from the material-dropping hole on circular hole, the supporting disk, then exported by screw auger.
The present invention compared with prior art, its advantage is:
1, owing to set up the feeding control apparatus, so that it is uniform and stable to fall into the biomass powder amount of screw auger, material also is not easy to make somebody a mere figurehead in the barrel simultaneously, and feeding capacity is stable.
2, because the rated output of screw auger greater than the feeding capacity that enters coupling tunnel from material-dropping hole, has guaranteed the timely output of biomass powder.
3, simple in structure, the strong adaptability to material, stable and reliable working performance.
