Abstract

The invention provides a biomass powder feeder. A conveying device drives a screw auger through a speed reducing motor in a direct connection mode. The biomass powder feeder is characterized in that: a round hole is formed at the center of the bottom of a material cylinder; a connecting cylinder is vertical to the screw auger, and the bottom of the connecting cylinder is communicated with the screw auger; a bearing sleeve is arranged at the center of a support disc which is fixedly mounted at the top end of the connecting cylinder; the support disc is located on the baring sleeve, and blanking holes are uniformly distributed around the bearing sleeve; the upper end of a rotary shaft is fixedly connected with the output end of a speed regulating motor, and the lower end of the rotary shaftpasses through the round hole to be inserted into the bearing sleeve; the rotary shaft is provided with a conical material blocking cylinder above the round hole; the diameter of the bottom surface of the conical material blocking cylinder is greater than the diameter of the round hole; multiple scraping plates are fixedly mounted on the rotary shaft below the conical material blocking cylinder; the rotation diameter of each scraping plate is slightly less than the diameter of the material cylinder, and a certain clearance is reserved between the bottom side and the cylinder bottom; and the rated output of the screw auger is greater than the quantity of feed entering the connecting cylinder from the blanking holes. The biomass powder feeder provided by the invention takes biomass as a feeding object, realizes uniform and stable feeding, and has the advantages of simple structure, small volume and excellent working performance.

Description

technical field [0001] The invention provides a biomass powder feeder, which belongs to the technical field of renewable energy utilization. Background technique [0002] Biomass pyrolysis and liquefaction is one of the ways to effectively utilize biomass energy. The bio-oil produced by it can be directly used as fuel oil in boilers and other combustion equipment, and can also be used in internal combustion engines instead of diesel and gasoline after catalytic hydrogenation and other improved treatments. Extract specialty or high value-added chemicals. The normal operation of the biomass pyrolysis liquefaction plant must first ensure the stability, continuity and uniformity of its feeding. However, in actual production, due to the characteristics of low density, easy compression and strong adhesion of biomass powder, it is easy to be overhead in the feeder or block the feeder after being compacted. At present, the feeding equipment of biomass pyrolysis and liquefaction de...
