Stirring device for livestock and poultry excrement aerobic fermentation tank

Abstract

The invention discloses a stirring device for livestock and poultry excrement aerobic fermentation tank. The stirring device comprises a main shaft, stirring blades and stirring blade supporting plates; the main shaft is of a tubular structure, and a cavity longitudinally penetrating through a tube body is formed in the main shaft; the stirring blade supporting plates are arranged on the pipe wallof the main shaft and are divided into five layers from bottom to top along the pipe wall; the stirring blades are arranged on the stirring blade supporting plates, the number of the blades on each layer is sequentially 3, 3, 2, 2 and 2 from bottom to top, and the stirring blades on each layer are evenly distributed and welded to the main shaft. According to the device, livestock and poultry excrement can be fully stirred in the fermentation tank, the fermentation reaction efficiency is improved, stable and reliable operation of a stirring device and a stirring shaft of the fermentation tankis guaranteed, operation is easy, the service life is long, the equipment failure rate and the manufacturing cost are low, installation is rapid, maintenance is convenient, and application and popularization are facilitated.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a stirring device for an aerobic fermentation tank of livestock and poultry manure. Background technique [0002] The breeding industry is booming, and the waste from livestock and poultry breeding is increasing year by year. If livestock and poultry manure cannot be properly treated, on the one hand, it will cause serious pollution to the environment. For example, it causes eutrophication of water bodies, groundwater pollution, air pollution by odor, and harm to human health. The content of ingredients is relatively high, and it is a good source for the production of organic fertilizers. If the billions of tons of livestock and poultry manure produced every year can be collected and processed, and then rationally used, it will be a huge fortune. [0003] The aerobic fermenter for livestock and poultry manure solves this problem very well. Aerobic fe...

AI Technical Summary

Problems solved by technology

There are defects in the structural design of the traditional stirring device, which makes it difficult to fully stir, which affects the efficiency of the fermentation reaction, and the insufficiently fermented livestock and poultry manure is likely to cause secondary pollution to the environment
