Fermentation device for organic fertilizer

Abstract

The invention discloses a fermentation device for organic fertilizers, which belongs to the technical field of fermentation devices. A fermentation device for organic fertilizers includes a fermentation silo, a power device and a stirring device; the stirring device includes a first stirring part and a second stirring part , the first stirring member includes an inner helix and an outer helix; the inner helix is ​​left-handed, and the outer helix is ​​right-handed; when stirring, the inner helix moves the material to the left, and the outer helix moves the material to the right ; The stirring device is electrically connected with the power device, and the stirring device is designed to be a mixed mode of uniaxial double helix. After the organic fertilizer enters the tank, the outer helix will push the organic fertilizer from the left end to the right end, and the inner helix will then Move the organic fertilizer in the opposite direction, the organic fertilizer in the inner layer is pushed to the left end and rolls from the inside out, which is conducive to the full mixing of the organic fertilizer during the mixing process, making the mixing efficiency higher, and the power device can generate electricity, reducing the usual The temperature increase problem of energy consumption such as electricity temperature increase and coal temperature increase.

Description

technical field [0001] The invention relates to a fermentation device for organic fertilizers, in particular to a fermentation device for organic fertilizers. Background technique [0002] In recent years, my country's livestock and poultry breeding industry has developed rapidly, and a large amount of livestock and poultry manure has also been produced while meeting the needs of social livestock products. Livestock and poultry manure needs to be composted and fermented, which can increase the content of humic acid, and can kill some pathogenic bacteria, insect eggs and weed seeds, etc., and microorganisms can also decompose organic matter during the fermentation process, producing a large amount of crops that can be used for crops. The absorbed nutrients such as nitrogen and alum, and the composted manure is a good crop fertilizer and has good application value. [0003] Influenced by the prior art, the current microbial organic fertilizers use high temperature treatment t...

AI Technical Summary

Problems solved by technology

[0003] Affected by the existing technology, the current microbial organic fertilizer uses high temperature treatment to eliminate harmful substances such as Escherichia coli and insect eggs in livestock and poultry manure during the first step of decomposing, especially in severe cold areas. At the same time, most of the raw materials are piled up in the fermentation equipment for fermentation during stirring. At intervals, it is necessary to use the stirring device to plow and ventilate the fertilizer. The defects of this organic fertilizer fermentation are: first, the fermentation temperature It is not easy to control. In winter, the fermentation temperature is too low, the fermentation is not complete and the speed is slow. Since the tiller cannot turn over the raw materials at the bottom of the fermentation tank, the oxygen supply to the bottom of the fermentation tank is insufficient, which not only prolongs the fermentation time , also affects the quality of fertilizer efficiency of organic fertilizer; at the same time, affected by the external air temperature, the fermentation device of the prior art only heats the organic fertilizer through the insulation layer, resulting in the internal air temperature passing too fast
