Problems solved by technology

[0002] Straw, as a by-product of crop harvest, exists in large quantities in agricultural areas. The main treatment method in the past was incineration, but incineration not only brought environmental problems, but also caused a waste of resources. The existing method of recycling straw is mainly biogas. Manufacture, Manufacture of Organic Fertilizer and Manufacture of Building Materials
However, since the above-mentioned recycling methods require a large amount of equipment cost input, the economic motivation for agricultural practitioners to use them is not obvious. Therefore, how to form a complete set of integrated equipment for straw recycling has become a research hotspot for researchers.

Abstract

The invention relates to a straw recycling treatment method. A straw recycling treatment device is adopted for production and comprises a crushing cavity, a fine grinding cylinder, a conveying cavity,a mixing cavity, a casting mold pressing machine and a steam chamber. The method comprises the steps of crushing, grinding, modifying, mixing with cement, casting mold, pressing, and aerated curing.By arranging equipment of a specific structure, the efficiency of the whole method is improved, and integrated equipment manufacturing from primary raw materials to final products is achieved withoutpretreating the raw materials, so that the overall production cost is reduced, and the production stability is improved.
