Description

Technical Field

[0001] This utility model relates to the field of organic fertilizer production technology, specifically to a high-efficiency bio-organic fertilizer fermentation tank. Background Technology

[0002] Organic fertilizers are rich in diverse organic nutrients, which are gradually released and provide abundant nourishment to crops through the careful fermentation of microorganisms. Furthermore, the application of organic fertilizers not only significantly improves soil structure but also cleverly coordinates the distribution of water, fertilizer, gas, and heat in the soil, thereby comprehensively enhancing soil fertility and the land's productive potential.

[0003] Currently, the microbial fermentation process of organic fertilizers mainly relies on aerobic microorganisms. In the preparation of aerobic compost for livestock and poultry manure, this process typically involves several key steps, including pretreatment, primary fermentation, secondary fermentation, and subsequent fine processing and storage.

[0004] However, this traditional approach still has certain limitations. Through in-depth research, we found that most existing organic fertilizer fermentation devices employ a vertical fermentation tank design, relying on a stirring shaft and impeller for mixing. Unfortunately, this design often results in insufficient mixing of the compost material at the bottom of the fermentation tank, preventing some materials from effectively participating in the fermentation process. This not only affects the overall fermentation effect but also wastes valuable resources. While existing technologies may already offer solutions to these problems, this project aims to provide an alternative or replacement solution. Utility Model Content

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a high-efficiency biological organic fertilizer fermentation tank, comprising: a fermentation tank, a fermentation stirring structure, and an aeration structure, wherein the fermentation stirring structure and the aeration structure are installed on the fermentation tank, and the fermentation stirring structure includes: a pair of horizontal stirring shaft tubes, a pair of horizontal bidirectional threaded blades, two pairs of rotating rings, several concave excavation blocks, two pairs of spider web aeration tubes, a stirring gear set, a stirring drive motor, a diversion aeration tube, an aeration pump, a stretching shaft tube, stretching threaded blades, a stretching gearbox, a stretching drive motor, and auxiliary fermentation components;

[0006] A pair of horizontal stirring shafts are inserted into the fermenter via bearings; a pair of horizontal bidirectional threaded blades are respectively installed on the pair of horizontal stirring shafts; two pairs of rotating rings are respectively fitted onto the pair of horizontal stirring shafts; several concave excavation blocks are respectively installed on the two pairs of rotating rings; two pairs of spiderweb aeration pipes are respectively installed on the two pairs of rotating rings, and the two pairs of spiderweb aeration pipes are respectively connected to the pair of horizontal stirring shafts and the several concave excavation blocks; a stirring gear set is fitted onto the pair of horizontal stirring shafts; the driving end of the stirring drive is connected to the stirring gear set; a stretching shaft is inserted into the inside of the fermenter via bearings; a diversion aeration pipe is inserted into the pair of horizontal stirring shafts and the stretching shaft via bearings; an aeration pump is connected to the diversion aeration pipe; stretching threaded blades are installed on the stretching shaft; a stretching gearbox is fitted onto the stretching shaft; the driving end of the stretching drive is connected to the stretching gearbox; and the auxiliary fermentation assembly is installed on the fermenter.

[0007] It should be noted that, as described above, the stirring drive motor operates, driving the stirring gear set, which in turn drives a pair of horizontal stirring shafts to rotate stably. These horizontal stirring shafts drive two pairs of rotating rings, which in turn drive several concave digging blocks to rotate stably and vertically relative to each other. This achieves the stable vertical and relative rotation of the fertilizer at the bottom of the fermentation tank, thus guiding the fertilizer upwards. The pair of horizontal stirring shafts drive horizontal bidirectional threaded blades, which in turn guide the fertilizer towards the rotating rings. Simultaneously, the stretching drive motor operates, driving the stretching gearbox on its drive end. The stretching gearbox drives the stretching shaft on its inner side to rotate stably, which in turn drives the stretching threaded blades to rotate stably. This achieves the upward guidance of the fertilizer inside the fermentation tank, guiding the fertilizer at the bottom towards the two pairs of rotating rings. Simultaneously, the horizontal rotation guides the fertilizer upwards towards the two pairs of rotating rings and along the stretching shaft. The auxiliary fermentation components regulate the temperature and humidity of the fermentation process.

[0008] Preferably, the auxiliary fermentation component includes: a spray ring, a spray pump, three coiled electric heaters, three coiled heating rods, three pairs of auxiliary supports, a spray box, and a temperature sensor;

[0010] It should be noted that, as described above, the raw materials inside the spray box are guided to the spray ring by the spray pump, and the fertilizer inside the fermentation tank is sprayed through the spray ring. At the same time, the air inside the horizontal stirring shaft tube and the stretching shaft tube is heated by three coiled electric heaters, and the inside of a pair of horizontal stirring shaft tubes and the stretching shaft tube is rapidly aerated by the air pump. This allows the high-temperature gas to be guided to the inside of two pairs of spider web aeration pipes, and the fertilizer inside several concave excavation blocks is aerated through the two pairs of spider web aeration pipes, thereby achieving rapid temperature-controlled mixing.

[0011] Preferably, the fermenter is provided with a feeding Z-shaped pipe, and the feeding Z-shaped pipe is provided with feeding spiral blades and a feeding drive motor.

[0012] Preferably, the inner sides of the stretching shaft tube and the two pairs of spider web inflatable tubes are respectively provided with a plurality of horn-shaped unidirectional plates.

[0013] Preferably, the bottom of the fermentation tank is provided with an arc-shaped support block.

[0014] Preferably, the feeding Z-shaped tube is equipped with a feeding valve. Beneficial effects

[0015] This invention provides a high-efficiency bio-organic fertilizer fermentation tank. It offers the following advantages: compared to existing technologies, this high-efficiency bio-organic fertilizer fermentation tank integrates high-efficiency stirring, vertical tilting, and temperature-controlled spraying, significantly improving the efficiency and quality of fertilizer fermentation. The device utilizes a stirring drive to power a stirring gear set, which in turn drives a pair of horizontal stirring shafts to rotate stably. This, in turn, drives two pairs of rotating rings and concave excavation blocks to rotate vertically relative to each other, achieving stable tumbling and upward flow of fertilizer from the bottom of the fermentation tank. Simultaneously, the design of horizontal bidirectional spiral blades further promotes the flow and mixing of fertilizer towards the rotating rings. The synergistic action of the stretching drive and stretching gearbox drives the stretching shaft and stretching spiral blades to rotate, drawing fertilizer upward and enhancing the mixing effect. Furthermore, the device integrates auxiliary fermentation components. A spray pump evenly sprays raw materials into the fermentation tank, while three coiled electric heaters heat the air inside the stirring shafts. A rapid aeration pump introduces high-temperature gas into the spiderweb aeration pipe, aerating and temperature-controlled stirring the fertilizer within the concave excavation blocks, achieving rapid and uniform fermentation and mixing of the fertilizer. This device not only improves the efficiency and uniformity of fertilizer fermentation but also provides ideal environmental conditions for fertilizer fermentation through precise temperature control and a spraying system, ensuring improved fertilizer quality.
