Intermediate bunker of biomass boiler taking straw as fuel

Abstract

An intermediate bunker of a biomass boiler taking straw as fuel consists of a material evening ratchet wheel, intermediate ratchet wheels, unloading packing augers and a stock bin, wherein the stock bin is of a quadrangular prismatic table shape with a big upper part and a small lower part; the material evening ratchet wheel consists of a drive motor, a ratchet wheel rod and a calthrop which is radially welded on the upper surface; the axis direction of the material evening ratchet wheel is vertical to the axis directions of the unloading packing augers; the intermediate ratchet wheels consist of drive motors, ratchet wheel rods and calthrops which are radially welded on the upper surfaces; the axis directions of the intermediate ratchet wheels are parallel with the axis directions of the unloading packing augers; every two intermediate ratchet wheels oppositely rotate to form a group; multiple groups of intermediate ratchet wheels form one layer of intermediate ratchet wheels; the multiple layers of intermediate ratchet wheels are uniformly arranged along the height direction of the stock bin; the free height difference between adjacent two layers of intermediate ratchet wheels is 1.2-1.8m; the unloading packing augers are driven by unloading motors. Due to the scattering effects of the material evening ratchet wheel and the intermediate ratchet wheels, straws cannot twine and be connected; under the bearing effect of the intermediate ratchet wheels, the unloading packing augers cannot be jammed, the space of the stock bin is fully utilized, and the furnace shut down accident caused by faults of a transmission system is avoided.

Description

technical field [0001] The invention relates to an intermediate silo, in particular to an intermediate silo system for a biomass boiler using straw as fuel, and belongs to the technical field of fuel transportation intermediate storage. Background technique [0002] Fossil energy such as coal, oil and natural gas not only provides energy and power for the development of human society, but also causes great harm to the living environment of human beings, such as greenhouse effect, NOx emissions, SO 2 emissions and dust pollution. At the same time, human society is also facing the problem of fossil energy depletion. Therefore, seeking to develop new energy sources and realizing the sustainable development of society has been paid more and more attention by countries all over the world. Biomass energy, as a renewable clean energy, has a good development prospect. The National Academy of Sciences of the United States clearly stated in "Energy Transformation 1985-2010": "By 20...
