A buried fermentation device for reusing agricultural straw

Abstract

The invention discloses a buried fermentation device for reusing agricultural stalks. The invention can quickly realize the crushing of straws, realize rapid fermentation treatment, and is suitable for large-scale fermentation treatment. Moreover, the invention can directly put straws into After pulverization and fermentation, the fermented fermented material is automatically output, which improves the degree of automation and facilitates subsequent reprocessing and utilization. The arrangement of the outer heat insulation layer, anchoring seat, and pedestal of the present invention can effectively prevent cracks in the fermenter, etc. Problem, moreover, the crushing mechanism of the present invention has high crushing efficiency, and can quickly realize large-scale crushing by using the continuous movement of the spiral path, which greatly ensures large-scale fermentation treatment.

Description

technical field [0001] The invention relates to the technical field of agricultural straw fermentation, in particular to a buried fermentation device for reusing agricultural straw. Background technique [0002] In recent years, crop straw has become a new source of rural non-point source pollution. Every year during summer harvest and autumn and winter, a large amount of wheat, corn and other stalks are always burned in the fields, producing a lot of thick smoke, which not only becomes the bottleneck of rural environmental protection, but even becomes the chief culprit that affects the urban environment. In fact, crop straw is a very valuable biomass energy resource in the agricultural ecosystem. The comprehensive utilization of crop straw resources is of great significance to promote farmers' income increase, environmental protection, resource conservation and sustainable development of agricultural economy. From the perspective of foreign countries, especially in develo...

Problems solved by technology

[0003] For the utilization of straw, one of the most important processes is to ferment agricultural straw. Due to the large amount of agricultural straw, the fermentation volume is very large during fermentation. The current simple fermentation device is difficult to apply, so , the buried structure is the most convenient and effective for straw fermentation

However, the buried fermentation structure not only often causes cracks due to the temperature difference between spring, summer, autumn and winter, but also generally fills the whole straw directly, which slows down the fermentation of the whole straw, which affects the fermentation efficiency.
