Thermal cycle excrement aerobic fermentation tank

Abstract

The invention discloses a thermal cycle excrement aerobic fermentation tank. The thermal cycle excrement aerobic fermentation tank comprises a fermentation tank body, a vertical stirring shaft is arranged in the middle in the fermentation tank body, a plurality of stirring rulers are arranged on the periphery of the stirring shaft, the stirring shaft and the stirring rulers are provided with hollow pipelines, the stirring shaft is communicated with the hollow pipelines of the stirring rulers, and a plurality of aeration holes are formed in the outer sides of the stirring rulers; an annular aeration pipeline is also arranged at the upper part in the fermentation tank body; a plurality of aeration pipe bundles are arranged at the bottom of the annular aeration pipeline; the stirring shaft and the annular aeration pipeline are both communicated with a hot air conveying pipeline through an air inlet pipeline, a hot air outlet is formed in the top of the fermentation tank body, and the hotair outlet is communicated with the hot air conveying pipeline through a heat recovery pipeline and used for conveying humid and hot air in the fermentation tank body to the hot air conveying pipeline. According to the fermentation tank, humid and hot air of the fermentation tank body can be used for providing oxygen and a fermentation temperature environment required by fermentation for the fermentation tank body, and organic excrement with different water contents and different components can be treated.

Description

technical field [0001] The present disclosure belongs to the technical field of harmless treatment of feces aerobic fermentation, and in particular relates to a thermal cycle fecal aerobic fermentation tank. Background technique [0002] At present, more and more attention has been paid to the harmless treatment of organic materials such as livestock and poultry manure in farms. The method of using aerobic bacteria to ferment organic manure to produce organic fertilizer has been more and more used because of its low operating cost and high economic advantages. [0003] The inventors found that traditional aerobic fermentation of feces mostly adopts composting method, where the materials are put aside in the open air, and the oxygen is supplemented by regular mechanical ploughing to achieve the purpose of aerobic fermentation. This method requires manual operation, and the fermentation efficiency is low and the fermentation is uneven. Or leave the feces to ferment in a tank ...

AI Technical Summary

Problems solved by technology

[0003] The inventors found that traditional aerobic fermentation of feces mostly adopts the method of composting, and the materials are left in the open air, and mechanically plowed regularly to supplement oxygen to achieve the purpose of aerobic fermentation. This method requires manual operation, and the fermentation efficiency is low and the fermentation is uneven.

Or leave the feces in a tank with stirring and aeration for fermentation. This method is difficult to control the temperature and humidity in the tank for materials that are too dry or too wet, and it is easy to cause a large number of super-heated and super-humid fungi to die.
