Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of livestock and poultry manure composting, in particular to a device for rapidly composting solid livestock and poultry manure. BACKGROUND

[0002] Manure composting is a process in which manure is converted into stable substances through complex biochemical reactions under the action of microorganisms. Various microorganisms are involved, including aerobic and anaerobic decomposition and other chemical changes, which are affected by temperature, humidity, ventilation, and carbon-nitrogen ratio. Common composting methods include natural, composting, and biological fermentation, which can improve soil and increase fertility. Each method has its own characteristics. Dry fermentation and wet fermentation are the two main ways of manure treatment, each with its own characteristics. Dry fermentation is suitable for areas with high population density because the low water content makes it difficult for microorganisms to produce odors. The fermentation product is solid, making it easy to store and transport at a low cost. However, the low water content limits microbial metabolism, resulting in slow fermentation that requires long periods of time in a natural state and frequent turning to prevent material clumping and uneven fermentation. Wet fermentation is the opposite. The humid environment allows microorganisms to fully contact organic matter, resulting in high enzyme activity and rapid fermentation that can be completed in a few weeks. However, the process produces a pungent odor and the product is difficult to handle and store, as harmful microorganisms can easily grow during storage.

[0003] According to the patent network publicity "a device for rapidly composting solid livestock and poultry manure (publication number: CN 220537712U; application number: 202321455068.X)", the above-mentioned application optimizes the problem of "at present, solid livestock and poultry manure is generally added to a composting pool for fermentation. When the water content is low, the solid livestock and poultry manure is not easy to uniformly bubble. When the water content is high, the livestock and poultry manure becomes too dilute and the pool bottom accumulates liquid. Static composting of livestock and poultry manure in the pool results in poor water uniformity and low fermentation efficiency". However, the composting equipment in the above-mentioned application cannot mix and stir the dry and wet materials inside the device during use. During the fermentation process, the dry material gradually floats upwards under the action of the bubbles produced during fermentation, causing the dry material to separate from the wet material, reducing the fermentation bacteria content in the dry material, and reducing the composting efficiency.
