Description

Technical Field

[0001] The present invention belongs to the technical field of fertilizer fermentation and relates to a gas treatment device for fertilizer fermentation. Background Art

[0002] Fertilizer refers to a substance that provides one or more essential nutrients for plants and improves the properties of the soil and the soil fertility level. It is one of the material bases for agricultural production. Sludge, silt, feces, and waste treatment products generated in life have become the main raw materials for producing organic fertilizers.

[0003] For example, a patent with the publication number (CN113582747B) discloses a fertilizer fermentation device. When fermenting fertilizer, a large amount of heat will be generated. The heat will make the movement trajectory of gas molecules inside the heat-driven airbag more intense, thereby increasing the volume of the heat-driven airbag. When the volume of the heat-driven airbag increases, it will push the horizontal drive rod and the vertical drive rod to move, thereby causing the drive transmission mechanism and the flipping mechanism to work, achieving the purpose of dispersing the piled-up fertilizer and promoting the fermentation of the fertilizer.

[0004] When using the above technology, it is found that the following technical problems exist in the prior art: When the fertilizer is fermented, the fermentation process will cause the fertilizer to have a high humidity. The high humidity will cause the fertilizers to stick to each other during fermentation. The gas inside the stuck fertilizer blocks cannot be fully released. Therefore, harmful gases cannot be fully treated, and the remaining harmful gases will affect the quality of fertilizer fermentation. Summary of the Invention

To facilitate the formation of a sealed state for the fermentation barrel 1 and prevent the leakage of harmful gases therein, a closing air extraction cover 2 is provided at the top of the fermentation barrel 1. A fixing plate 3 is fixedly connected to one side of the fermentation barrel 1. To facilitate the extraction of harmful gases generated by fermentation in the fermentation barrel 1, a negative pressure air extractor 4 is fixedly connected to the top of the fixing plate 3.

A gas compression assembly is provided inside the compression seat 7, thus facilitating the introduction of air into the fermentation barrel 1 through the compression seat 7.

[0024] A gas release component is arranged at the bottom of the compression seat 7.

[0031] During operation, when it is necessary to treat the harmful gas generated in the fermentation barrel 1, by starting the servo motor 21, the output end of the servo motor 21 drives the transmission shaft 22 to rotate.

At the same time, the transmission shaft 22 drives the first transmission gear 26 to rotate through the belt seat 23 and the transmission belt 24, so that the first transmission gear 26 drives the first ring gear 20 to rotate. Then, the first ring gear 20 drives the stirring pipe 29 to rotate around its own center through the fixing frame 27. Then, while the stirring pipe 29 rotates with the first ring gear 20, it drives the stirring pipe 29 to rotate around its own center through the second ring gear 201 and the second transmission gear 30. When the stirring pipe 29 rotates in a circle with its own center as the circumference, it drives the stirring pipe 29 to rotate around the center of the first ring gear 20 through the first ring gear 20.
