Description

Straw bag smashing system with automatic unpacking, net removing and soil screening functions

Technical Field

The invention relates to the technical field of biomass straw treatment, in particular to a straw bag crushing system with automatic unpacking, net removing and soil screening functions.

Background

The biomass straw is used as a renewable energy source, and can convert biomass into methane and organic fertilizer through anaerobic fermentation, so that the purpose of carbon dioxide emission reduction is well achieved, and contribution is made to the aims of carbon neutralization and carbon peak reaching. In the process of transporting and collecting straws from the field to a fermentation plant, in order to save transportation cost and facilitate loading, unloading and storage, a 'straw bundling net' made of plastic yarns is usually required to be packed, and meanwhile, sand and soil are inevitably mixed in the process of packing straws. From dry to wet anaerobic fermentation processes, strict requirements are imposed on the fermentation size of the straws to ensure the fermentation efficiency and effect. Therefore, the straw is required to be crushed, and the straw netting and the sandy soil are required to be removed, because the plastic straw netting and the sandy soil cannot participate in the fermentation reaction, the fermentation process or equipment is adversely affected once the straw enters a fermentation system, and the quality of the organic fertilizer is also reduced because the organic fertilizer is mixed with the plastic straw netting and the sandy soil.

At present, the domestic straw pretreatment system generally exists: 1. the net removing and net detaching functions are not needed, and a large amount of manual work is needed to remove the net in advance; 2. or the straw screen does not have the soil screening function, or a large amount of straws are screened out and wasted after the straws are crushed and then screened out; 3. the yield is small, the energy consumption is high, a two-stage crushing mode is adopted, and the single-ton treatment cost is high.

Therefore, it is necessary to provide a novel biomass straw pretreatment system, which can have three functions of net detachment, net removal, impurity removal and crushing.
