Organic fertilizer fermentation device and using method thereof

Abstract

The invention discloses an organic fertilizer fermentation device and a using method thereof. The fermentation device comprises a fermentation shell, a rotating structure and a stirring structure, wherein the feeding structure is arranged at the top of the fermentation shell, a through hole is formed in the top of the feeding structure, and the feeding structure comprises at least two excrement inlets, a water pipe and an oxygen pipe; the rotating structure comprises a rotating motor; the stirring structure is arranged in the fermentation shell and comprises a stirring rod and two stirring blades, the top of the stirring rod penetrates through the through hole to be connected with an output shaft of the rotating motor, the stirring rod is hollow and is provided with a partition plate in the vertical direction, the partition plate divides the interior of the stirring rod into a water cavity and an oxygen cavity, the water cavity is communicated with a water pipe, two columns of drainage holes are formed in the side wall of the water cavity, the oxygen cavity is communicated with an oxygen pipe, two columns of vent holes are formed in the side wall of the oxygen cavity, a plurality of through holes are formed in the stirring blades, and blades are arranged in the through holes. The fermentation time is shortened, the production efficiency is improved, the manure is uniformly fermented, and the uniform quality of the organic fertilizer is ensured.

Description

technical field [0001] The invention relates to the technical field of organic fertilizer production, in particular to an organic fertilizer fermentation device and a use method thereof. Background technique [0002] Organic fertilizers are rich in nutrients needed for crop growth, which can improve soil, improve crop quality, and increase crop yield. In the prior art, because there are many chemical components such as nitrogen, phosphoric acid, and calcium in animal manure, animal manure and straw are often used to make organic fertilizer, which can not only effectively turn waste into wealth, but also avoid and control the increasingly serious environmental pollution. In the production process of organic fertilizer, fermentation is the most important step, and the fermentation step can achieve the effect of killing diseases and insect pests and increasing nutrients. [0003] However, when most of the fermentation devices are in use now, after the straw is crushed, the an...

AI Technical Summary

Problems solved by technology

[0003] However, when most of the fermentation devices are in use now, after the straw is crushed, the animal manure and straw are directly put into the fermentation tank for stirring, and then water and oxygen are injected to assist the fermentation. There are many problems in this way, such as the fermentation process is relatively slow Long and low production efficiency; although agitators are also used, most of the water is gathered in the lower layer of the fermenter and cannot infiltrate the feces on the upper layer; the oxygen is also not in sufficient contact with the feces in the center, especially the feces at the bottom of the fermenter are generally difficult to be digested. Stir evenly, and cannot absorb oxygen, resulting in hardening of the final organic fertilizer
