Straw feeding system

Abstract

The invention belongs to the technical field of biomass fuel, and particularly relates to a straw feeding system. The feeding system comprises a sawing machine and a stirring machine, the sawing machine is sequentially provided with a plate pressing mechanism and a roll crushing mechanism in the straw moving direction, the plate pressing mechanism is used for compressing fluffy straw into plate-shaped straw, the roll crushing mechanism is used for sawing the plate-shaped straw, and the stirring machine is sequentially provided with a transition hopper, an auger sheet, a plastic package layer, a knockout blade and a discharge port in the straw moving direction. Biomass straw raw materials are crushed into biomass meeting the specified particle size by the straw plate pressing sawing machine, the biomass enters the hopper under the action of the stirring blade and then is conveyed to the knockout blade under the action of the auger, the biomass cannot be accumulated at the discharge port under the rotation action of the knockout blade, and a crusher and a feeding device are combined into a whole, so feeding is more convenient, straw is treated in a totally-closed mode, and dust pollution cannot be caused.

Description

technical field [0001] The invention belongs to the technical field of biomass fuels, and in particular relates to a straw feeding system. Background technique [0002] The realization of the global carbon neutrality goal mainly relies on carbon-neutral biomass fuel instead of coal, and high-quality low-cost fuel gas conversion of carbon-neutral biomass energy, replacing fossil fuel oil and natural gas, and supporting the entire national economy. Thus, the low-cost and high-efficiency production of intermediate processing of fluffy biomass raw materials to industrial energy has become an urgent problem to be solved. For a long time, fluffy biomass raw materials have been used in the processing of feed and traditional Chinese medicine. Due to the high end value, high processing costs can be accepted. As for the industrialization of biomass to industrial energy, since the industrial revolution, the amount of coal used is about 3 billion tons per year, and the demand for bioma...
