Therefore, a fermentation device for industrial fertilizers and a fermentation method thereof are proposed to solve the above problems. Summary of the Invention

The motor drives the main shaft to rotate, and the main shaft drives the stirring paddle to rotate, and the stirring paddle stirs the material, and the squeezed water flows to the bottom of the first filter plate and the second filter plate. At the same time, some inorganic impurities such as weeds that are difficult to decompose pass through the first filter plate and fall onto the second filter plate, thereby completing the separation of different substances during fermentation. When the main shaft rotates, it drives the sleeve shaft to rotate, and the sleeve shaft drives the connecting block to rotate along the circumference of the main shaft axis, and the connecting block drives the rotating plate to rotate circumferentially, and the rotating plate drives the steel brush to rotate circumferentially. When the steel brush rotates, it contacts and rubs with the first filter plate and the second filter plate, thereby brushing off impurities stuck in the first filter plate and the second filter plate.

[0006] Preferably, the scraping device includes a clamping rod, the end of the clamping rod away from the stirring paddle is fixedly connected to a pushing scraper, the upper and lower ends of the pushing scraper are fixedly connected to support sliders, the scraping device also includes an upper arc guide rail, the inner wall of the fermentation tank is fixedly connected to the lower arc guide rail, the two sides of the pushing scraper are fixedly connected to toothed scrapers, the top of the pushing scraper is fixedly connected to a U-shaped clamping plate, the clamping rod and the stirring paddle are fixedly connected at one end away from the main shaft, the upper arc guide rail is fixedly connected to the inner wall of the fermentation tank, the supporting slider is slidably connected to the inner surface of the upper arc guide rail, and the supporting slider is slidably connected to the inner surface of the lower arc guide rail. The pushing scraper is in contact with the inner wall of the fermentation tank, and the toothed scraper is in contact with the inner wall of the fermentation tank. The rotation of the stirring paddle drives the clamping rod to rotate circumferentially along the axis of the main shaft. The clamping rod drives the pushing scraper to rotate circumferentially and scrapes off the material adhered to the inner wall of the fermentation tank. When the pushing scraper rotates circumferentially, it drives the supporting sliders at the upper and lower ends to slide in the upper arc guide rail and the lower arc guide rail respectively, thereby increasing the fulcrum when the pushing scraper rotates, preventing the force arm from being too long, and reducing the rotational resistance of the pushing scraper. The pushing scraper drives the toothed scraper to rotate circumferentially. When the toothed scraper rotates, it removes the material that is difficult to scrape through the oblique angle between it and the arc surface of the inner wall of the fermentation tank.

The circumferential surface and the inner surface of the U-shaped pallet are in contact with each other, and the fermentation agent is added to the spreading box through the feeding tube. The fermentation agent falls into the fermentation tank through the material retaining tube and the spreading head and contacts the material, pushing the scraper to rotate circumferentially, which drives the U-shaped pallet to rotate circumferentially. The U-shaped pallet drives the transmission push rod and the balance slider to rotate circumferentially in the arc slide rail, and the transmission push rod drives the spreading box to rotate. When the spreading box rotates, the fermentation agent inside is evenly distributed in the spreading box due to the influence of centrifugal force. When the amount of fermentation bacteria added to the spreading box is higher than the material retaining tube, the fermentation agent falls onto the material from multiple material retaining tubes and the spreading head at the same time, so that it is more evenly distributed on the material. The rotation of the spreading box drives the annular sleeve to rotate on the movable retaining ring, so as not to affect the feeding of the fermentation agent. At the same time, the rotation of the spreading box further increases the falling area of the fermentation agent.

[0008] A fermentation method for an industrial fertilizer fermentation device comprises the following steps: Step 1: First, pour the material into the fermentation tank through the feed pipe, start the motor, the motor drives the main shaft to rotate, the main shaft drives the stirring paddle to rotate, and the stirring paddle stirs the material; Step 2: Then, the fermentation agent is added to the spreading box through the feeding pipe, and then falls onto the material in the fermentation tank through the material blocking pipe and the spreading head on the spreading box, and is mixed with the material by the stirring of the stirring paddle; Step 3: Subsequently, oxygen is supplied to the fermentation tank through the air inlet pipe to increase the growth rate and activity of aerobic microorganisms, and to increase the temperature inside the fermentation tank to promote the decomposition of organic matter and harmful organisms by aerobic microorganisms; Step 4: Finally, after a certain period of fermentation, open the discharge pipe and take out the fermented fertilizer from the discharge pipe for subsequent processing. Then, discharge the water of the impurities separated in the fermentation tank and clean the fermentation tank.

[0009] The present invention adopts the above technical solution, which can bring the following beneficial effects: 1. The fermentation device of the industrial fertilizer uses a stirring paddle to stir the material to ensure uniform fermentation of the material and avoid agglomeration. At the same time, it squeezes out excess water in the material to prevent excess water from affecting the decomposition and conversion of organic matter, thereby improving the fermentation efficiency. Some inorganic impurities such as weeds that are difficult to decompose fall onto the second filter plate through the first filter plate, thereby completing the separation of different substances during fermentation and further improving the fermentation efficiency. When the steel brush rotates, it contacts and rubs with the first and second filter plates, thereby brushing off impurities stuck in the first and second filter plates, preventing the first and second filter plates from being blocked, improving the efficiency of material filtration and separation, and further promoting the fermentation efficiency.

[0010] 2. In the fermentation device of industrial fertilizer, the card rod drives the scraper to rotate in a circle and scrape off the materials adhering to the inner wall of the fermentation tank, preventing the materials from accumulating on the inner wall of the fermentation tank for a long time and being difficult to remove. At the same time, it prevents microorganisms from having difficulty in fully contacting with the materials adhering to the inner wall of the fermentation tank, thereby causing insufficient decomposition of organic matter in some materials, thereby improving the fermentation effect.

[0011] 3. The fermentation device of industrial fertilizer supports the sliders to slide in the upper and lower arc guide rails respectively, thereby increasing the fulcrum when the scraper is pushed to rotate, preventing the force arm from being too long, reducing the rotational resistance of the scraper, and making it easier for the scraper to scrape the material. The toothed scraper removes the difficult-to-scrape material, improving the scraping efficiency of the material, further preventing the material from adhering to the inner wall of the fermentation tank, and enabling the stirring paddle to fully stir all the materials, thereby improving the decomposition effect of microorganisms on organic matter in the materials.

[0012] 4. In the fermentation device for industrial fertilizers, the fermentation agent falls into the fermentation tank through the material retaining pipe and the spreading head and contacts the material. After sufficient stirring and mixing, the fermentation process is promoted, the fermentation efficiency and output are improved, and the quality of the fermented material is improved. The fermentation agent falls onto the material from multiple material retaining pipes and the spreading head at the same time, so that it is more evenly distributed on the material, thereby improving the mixing efficiency of the fermentation agent and the material.

[0013] 5. In the fermentation device of industrial fertilizer, the rotation of the spreading box drives the annular shell to rotate on the movable clamping ring, so as not to affect the feeding of the fermentation agent. At the same time, the rotation of the spreading box further increases the falling area of the fermentation agent, so that the fermentation agent and the material are mixed more fully, further improving the efficiency and quality output of the fermentation.
