Description

Technical Field

[0001] The utility model relates to the technical field of straw processing, in particular to a wall-breaking and decomposing device for straw processing. Background Art

[0002] Assessment results show that in 2015, the theoretical resource volume of major crop straw in China was 1.04 billion tons, with 900 million tons of it collectable, resulting in a straw comprehensive utilization rate of 20.1%. Straw is the primary raw material for papermaking. The 2015 annual report of the China Paper Association indicates that less than 20 million tons of straw is converted into pulp annually in my country. Therefore, there is a broad market potential for straw processing.

[0003] Steam explosion treatment of crop straw utilizes the thermal effects of steam. Under high temperature and pressure, this process degrades hemicellulose into oligosaccharides and monosaccharides, partially degrading lignin and cellulose and softening the lignin. Simultaneously, the sudden release of pressure, the expansion of the high-temperature, high-pressure steam, and the internal and external friction of the straw during transportation in the pipeline tear the straw cells and loosen their cell walls, thereby altering the overall structure of the crude fiber and its chemical chain structure. After steam explosion, the straw produced by the Agricultural Farmers Association becomes soft, tobacco-like, brown, and fragrant.

[0004] Chinese utility model patent CN213925647U discloses a steam explosion device for biomass materials. A steam pipeline is installed inside the steam explosion device to increase the permeability of the material accumulated at the bottom. This device is used for biomass materials, which are fine materials. Traditional Chinese medicine waste residue is mainly wood material, which has a high density and soft texture and poor steam permeability. Therefore, the above device is difficult to fully and evenly steam explode the traditional Chinese medicine waste residue.

[0005] Based on this, this proposal proposes a straw wall breaking and decomposition device for processing. Utility Model Content
