Organic fertilizer fermentation apparatus

Abstract

The invention belongs to the field of organic fertilizer processing, and relates to an organic fertilizer fermentation apparatus which comprises a fermentation mechanism and an oxygen supply mechanism, wherein the fermentation mechanism comprises a fermenting tank; the top of the fermenting tank is fixedly provided with a sun shed; a stirrer is installed inside the fermenting tank; the bottom of the fermenting tank is provided with a one-way gas duct; the oxygen supply mechanism comprises a sterilizing chamber; the sterilizing chamber is connected with an inlet end of a hot gas pump through a gas pipe; and an outlet end of the hot gas pump is connected with the one-way gas duct through a gas pipe. The organic fertilizer fermentation apparatus can perform sterilization and oxygen supply on the organic fertilizer, so that the fermentation activity is enhanced, thereby shortening the fermentation period and ensuring the fermentation quality.

Description

technical field [0001] The invention belongs to the field of organic fertilizer processing and relates to an organic fertilizer fermentation device. Background technique [0002] According to the survey of the State Environmental Protection Agency, the output of livestock and poultry manure in my country was 1.9 billion tons in 2000, which was 2.4 times the amount of industrial waste produced in my country in that year. By 2001, the national annual output of livestock and poultry manure was 2.144 billion tons. tons, and the output of livestock and poultry sewage was 12.442 billion tons. According to statistics such as Chen Xuemei from the Eco-Environmental Research Center of the Chinese Academy of Sciences, by 2010, the discharge of manure from livestock and poultry farming in my country will reach 4.5 billion tons. The production of organic fertilizer from livestock and poultry manure is an important way to solve the problem of resourceful, harmless and effective return of ...

Problems solved by technology

[0005] The aerobic decomposition of microorganisms is an important guarantee for the fermentation of organic fertilizers, but after fermentation and composting, the water distribution is uneven, and the bottom layer contains a lot of water, which makes the bottom oxygen content too low, and the fermentation activity of aerobic microorganisms is weakened, prolonging the fermentation cycle; moreover, During the fermentation process, the production of harmful bacteria needs to be specially controlled. Excessive harmful bacteria will affect the fermentation process, resulting in a decrease in the yield of fermented products. In severe cases, it may even lead to the failure of the entire fermentation process. not sterilized
