Technical Field
[0001] This utility model belongs to the field of organic fertilizer processing technology, specifically relating to an organic fertilizer fermentation tank. Background Technology
[0002] The production of organic fertilizer requires mixing and fermenting raw materials in a fermentation tank. Current processing methods use motor-driven agitators to loosen the raw materials and accelerate fermentation. However, air needs to be injected into the raw materials during fermentation. Existing aeration methods typically involve inserting pipes into the raw materials for gas supply. While simple and easy, this method results in uneven gas distribution, leading to localized areas with excessive or insufficient gas, causing inconsistent fermentation results. Furthermore, the waste liquid generated during fermentation is difficult to separate and discharge in a timely manner, affecting the overall fermentation efficiency and product quality. Utility Model Content

[0017] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.
[0018] This utility model discloses an organic fertilizer fermentation tank, which mainly includes a tank body 1, a stirring mechanism 2, a ventilation structure 3, and a waste liquid separation component 4. The tank body 1 has a cylindrical structure with a feed inlet at the top and a discharge outlet on the side wall. A waste liquid discharge pipe 17 is provided at the bottom of the tank body 1. The stirring mechanism 2 consists of a drive motor 5, a main shaft 6, and several stirring blades 7. The drive motor 5 is fixedly installed at the center of the top of the tank body 1 by bolts. The main shaft 6 vertically penetrates the interior of the tank body 1 and is fixedly connected to the output end of the drive motor 5 by a coupling. The stirring blades 7 are evenly distributed along the outer wall of the main shaft 6 and are fixed to the main shaft 6 by welding. A scraper 16 is installed at the bottom of the main shaft 6. The scraper 16 is in contact with the inner wall of the tank 1 and is used to clean the raw materials attached to the inner wall of the tank 1. After the drive motor 5 is started, the main shaft 6 drives the stirring blades 7 to rotate, which stirs and mixes the materials in the tank 1. During the rotation, the scraper 16 is in close contact with the inner wall of the tank 1, which can effectively clean the materials attached to the inner wall of the tank 1, reduce material waste and keep the inner wall of the tank 1 clean.
[0019] like Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the ventilation structure 3 includes an annular air chamber 8 and a gas guide pipe 9. The annular air chamber 8 is installed in the middle section of the inner wall of the tank 1 by welding and surrounds the inner wall of the tank 1. The annular air chamber 8 is connected to an external gas supply device through the gas guide pipe 9. Several evenly distributed air holes are formed on the inner wall of the annular air chamber 8, with the air holes inclined towards the center of the tank 1 at an angle of 30°~45° to ensure that the gas is evenly distributed in the raw material. The bottom of the annular air chamber 8 is designed with an inclined structure and has a guide hole to guide condensate or other liquids to the bottom of the tank 1, preventing liquid accumulation from affecting the gas distribution. The external gas supply device supplies gas to the annular air chamber 8 through the gas guide pipe 9. The gas enters the tank 1 through the air holes on the inner wall of the annular air chamber 8. The design of the air holes being inclined towards the center of the tank 1 ensures that the gas is evenly distributed in the material, avoiding localized excessive or insufficient gas distribution.
[0020] like Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the waste liquid separation component 4 includes a filter plate 10 and a collection chamber 11. The filter plate 10 is horizontally fixed to the lower part of the tank 1 by welding. The surface of the filter plate 10 is evenly provided with a number of circular filter holes for separating waste liquid from solid raw materials. During the fermentation process, the waste liquid generated flows into the collection chamber 11 through the circular filter holes on the surface of the filter plate 10, and the waste liquid is separated from the solid materials. The waste liquid in the collection chamber 11 is discharged to the external waste liquid collection device through the waste liquid discharge pipe 17, thereby avoiding the impact of waste liquid retention on the fermentation process.
[0021] like Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the outer wall of the tank 1 is provided with a heat insulation layer 12, and an electric heating wire 13 is provided inside the cavity sandwiched between the heat insulation layer 12 and the tank 1. The electric heating wire 13 is distributed in a spiral shape, and its two ends are connected to an external power source through wiring terminals. The heat insulation layer 12 on the outer wall of the tank 1 can effectively reduce heat loss. The electric heating wire 13 generates heat after being powered by an external power source, which heats the inside of the tank 1 and maintains the temperature conditions required for fermentation. The spiral distribution design of the electric heating wire 13 allows the heat to be evenly transferred to the inside of the tank 1, meeting the temperature requirements of different fermentation stages.
[0022] like Figure 6 As shown, the exhaust port 14 is fixed to the top of the tank 1 by welding, and the activated carbon filter 15 is fixed inside the exhaust port 14 for easy disassembly and replacement; the gas generated during fermentation is discharged through the exhaust port 14, and the activated carbon filter 15 installed inside the exhaust port 14 can adsorb harmful gases and reduce environmental pollution.
[0023] After the entire fermentation process is complete, the operator can open the movable door, and the organic fertilizer will be discharged from the tank by the stirring mechanism.
[0024] With the cooperation of the above-mentioned components, the material in tank 1 can undergo efficient fermentation in a suitable temperature and gas environment, while the waste liquid can be quickly separated and discharged, ensuring the smooth progress of the fermentation process. This utility model solves the problems of uneven gas distribution and difficulty in timely separation of waste liquid in existing organic fertilizer fermentation tanks by optimizing the design of the ventilation structure and waste liquid separation components, thereby improving fermentation efficiency and product quality, and has significant technical effects and practical value.
[0025] Work process:
[0026] First, the organic material to be fermented is put into the tank 1 through the feed inlet. The drive motor 5 is started, and the drive motor 5 drives the main shaft 6 to rotate, which in turn causes the stirring blades 7 installed on the main shaft 6 to rotate together, stirring and mixing the organic material in the tank, ensuring that the material is heated and fermented evenly. Since the stirring blades 7 are evenly distributed from top to bottom along the main shaft 6, they can fully stir the material at different heights, improving the stirring effect.
[0027] During the stirring process, the ventilation structure 3 starts to work. The external air supply device introduces gas into the annular air chamber 8 through the air guide pipe 9. The gas is ejected from several air holes opened on the inner wall of the annular air chamber 8. Since the air holes are inclined towards the center of the tank 1 at an angle of 30 to 45 degrees, the ejected gas can penetrate deeper into the organic material, providing sufficient oxygen for microbial fermentation and promoting the fermentation process. At the same time, the bottom of the annular air chamber 8 is set with an inclined structure and has a guide hole. When there is condensate or other liquid accumulated in the annular air chamber, it can be discharged in time through the guide hole to avoid affecting the ventilation effect.
[0028] As the fermentation process proceeds, the organic materials gradually decompose to produce waste liquid. This waste liquid drips down through the circular filter holes on the filter plate 10 and enters the collection chamber 11. The filter plate 10 is horizontally fixed in the lower part of the tank body 1, which can effectively intercept organic materials and only allow waste liquid to pass through, thereby achieving the separation of waste liquid and solid materials. The separated waste liquid is discharged from the tank body 1 through the waste liquid discharge pipe 17 for subsequent treatment. The filter plate 10 is made of stainless steel and can withstand the corrosive substances produced during the fermentation process for a long time. The diameter of the evenly distributed circular filter holes on its surface is 1mm~3mm. This size design can effectively separate waste liquid and solid materials and avoid solid materials from clogging the filter holes.
[0029] In order to maintain a suitable temperature during fermentation, the outer wall of the tank 1 is provided with a heat insulation layer 12, which can reduce heat loss. At the same time, an electric heating wire 13 is provided inside the cavity between the heat insulation layer 12 and the tank 1. The electric heating wire 13 is distributed in a spiral shape. When the temperature inside the tank is low, the material inside the tank can be heated by the electric heating wire 13 to ensure that the fermentation process is carried out within a suitable temperature range.
[0030] In addition, some waste gas is generated during the fermentation process. This waste gas is discharged through the exhaust port 14 at the top of the tank 1. In order to reduce the pollution of the waste gas to the environment, an activated carbon filter 15 is installed inside the exhaust port 14, which can adsorb and filter the harmful substances in the waste gas. The purified gas is then discharged into the atmosphere.
[0031] Once the organic fertilizer has finished fermenting, the movable door on the side wall of tank 1 can be opened to discharge the fermented organic fertilizer from tank 1 for further processing or use. At the same time, the scraper 16 installed at the bottom of the main shaft 6 is in contact with the inner wall of tank 1. During the rotation of the main shaft 6, the scraper 16 can scrape off the material adhering to the inner wall of the tank, avoiding material residue and ensuring the cleanliness of the inside of the tank.
[0032] In summary, this organic fertilizer fermentation tank, through the synergistic effect of the stirring mechanism 2, the ventilation structure 3, the waste liquid separation component 4, and the heat preservation, heating, and waste gas treatment devices, can achieve efficient fermentation of organic materials and produce high-quality organic fertilizer.
[0033] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
