Technical Field

[0001] The utility model relates to the technical field of pig manure processing, in particular to a pig manure organic fertilizer fermentation and composting device. Background Art

[0002] Pig manure is an organic waste produced in the pig farming industry. It is not only a valuable resource in agriculture, but also an important part of the ecological environment that needs to be properly handled. Pig manure contains high organic matter and rich nutrients such as nitrogen, phosphorus, and potassium. It is a high-quality organic fertilizer. Pig manure has a fine texture and decomposes slowly. It is suitable as base fertilizer and can significantly improve soil fertility.

[0003] In the process of agricultural waste treatment and organic fertilizer production, pig manure is a common organic resource, and its fermentation treatment is a key step in converting it into high-efficiency organic fertilizer. However, the traditional pig manure fermentation process often faces problems such as uneven fermentation and low efficiency. This is mainly because the heat and gas generated during the fermentation process are not effectively utilized, resulting in uneven temperature and oxygen distribution in the fermentation environment, which in turn affects the fermentation effect and product quality. In order to overcome these problems, in recent years, an innovative pig manure fermentation treatment system has emerged. This system cleverly uses the heated gas generated during the fermentation process to drive a mechanical device to achieve automatic turning of the fermented material, thereby improving fermentation efficiency and product quality.

The flip plate 15 contains two sheets of different sizes and is installed at intervals on the outer wall of the rotating rod 14.

[0022] When used specifically, the present invention is a pig manure organic fertilizer fermentation and composting device. The pig manure enters the fermentation barrel 1 through the feeding assembly 2 and ferments inside the fermentation barrel 1. During the fermentation process, a large amount of heat energy gas is generated. The heat energy gas in the fermentation barrel 1 enters the hot air barrel 4 through the outlet pipe 7 connected to the cover plate 16.
