Description

Technical Field

[0001] The utility model relates to the technical field of comprehensive treatment of organic waste, in particular to a combined fermentation bin for crop straw and livestock and poultry manure organic matter. Background Art

[0002] With the improvement of people's living standards, the demand for livestock and poultry meat has continued to increase, promoting the rapid development of the animal husbandry industry. At the same time, the amount of manure generated during the breeding process has also increased. Combining it with crop straw for fermentation can produce high-quality organic fertilizer. On the one hand, the production of crop straw is increasing, and burning it pollutes the environment. Combining the two to produce organic fertilizer through fermentation is an effective way to utilize waste. Therefore, efficient and rapid fermentation is required, and large-scale fermentation tanks are essential. On the other hand, the technical level required to effectively treat organic matter from crop straw and livestock and poultry manure is also increasing. Fermenting these organic matter into organic fertilizer is a commonly used and effective treatment method. This method sends the above-mentioned organic matter into a fermentation bin for fermentation, utilizes the microorganisms present in the organic matter to decompose the organic matter, and generates heat at the same time, so that the temperature in the material pile in the bin rises to a certain temperature and maintains it for a certain period of time, thereby achieving the purpose of killing pathogenic microorganisms and viruses in the material. The fermentation bin used in this method is provided with a leachate collection device at the bottom of the bin. The leachate generated during the fermentation process enters the collection ditch through the pores on the cover plate of the bottom bin and is uniformly discharged to the sewage pool. The oxygen required for the production and reproduction of microorganisms during the fermentation process is also supplied by the fan through the pores on the cover plate.

[0003] However, when the moisture content of the material is high, if the excess water cannot be removed in time, a water film will form in the material pores, which will affect microbial reproduction. Similarly, when the pores are clogged, microbial anaerobic fermentation will occur, which not only prolongs the fermentation cycle but also produces gases and odors, mainly methane, causing secondary environmental pollution. In large-scale material fermentation processes, high methane production also poses the risk of explosion. To address this technical problem, this application proposes a combined fermentation chamber for crop straw and livestock and poultry manure organic matter. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a combined fermentation bin for crop straw and livestock and poultry manure organic matter.

The ventilation duct is also a sewage channel, and the ventilation duct has a slope to facilitate timely discharge of sewage. At the same time, the temperature of the pile layer in the bin and the oxygen content in the pile layer can be conveniently measured through the detection hole, and the fan driven by the variable frequency motor is feedback-controlled to ensure the ventilation required in the fermentation process and the supply of appropriate oxygen, thereby saving energy.
