Description

Technical Field

[0001] This utility model relates to the field of organic fertilizer production technology, specifically to an organic fertilizer fermentation device. Background Technology

[0002] Organic fertilizer is a fertilizer rich in humus and nutrients, made from organic waste such as animal and plant remains, livestock and poultry manure, and crop straw through microbial fermentation. Organic fertilizer fermentation devices have emerged to address this need, using mechanized and intelligent methods to simulate and accelerate the natural fermentation process. Modern fermentation devices can be categorized by process, including trough-type, tank-type, and windrow-type devices. They utilize aerobic microorganisms to rapidly decompose organic matter under suitable conditions, converting macromolecules into stable humus while simultaneously killing pathogens and weed seeds.

[0003] In some regions, gypsum powder, fly ash, and slag are added to fermentation tanks as raw materials for organic fertilizer fermentation to achieve waste recycling and utilization. However, these substances are not only fine-particled, making them prone to intrusion into the oxygen supply pipes or other mechanisms within the tank, but their tendency to clump can also clog air outlets or stirring rods, resulting in poor stirring or even complete failure to rotate, thus hindering fermentation. To address these issues, this invention provides an organic fertilizer fermentation device to solve the aforementioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an organic fertilizer fermentation device that solves the problems of poor fermentation results caused by the fine particles of gypsum powder, coal ash, and slag, which easily invade the oxygen addition pipe or other mechanisms inside the tank, and whose tendency to clump together can block the air outlet or the stirring rod, resulting in poor stirring effect or even failure to rotate.

[0009] Preferably, a crushing plow blade is fixedly connected to the rotating shaft, and the array of crushing plow blades is distributed on the rotating shaft. The crushing plow blades are used to cooperate with the shearing convex plate to shear the agglomerated raw material.

[0010] This utility model discloses an organic fertilizer fermentation device, which has the following beneficial effects: This organic fertilizer fermentation device, by setting a filter screen and upper and lower scraper plates at the air outlet, prevents the raw materials from accumulating and caking on the filter screen, which would eventually cause the air outlet to be blocked.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] This application provides an organic fertilizer fermentation device that solves the problem that substances such as gypsum powder, coal ash, and slag are not only fine-particled, making them easy to infiltrate the oxygen addition pipe or other mechanisms inside the tank, but also prone to caking, which can block the air outlet or the stirring rod, resulting in poor stirring effect or even failure to rotate, thus leading to poor fermentation effect.

[0020] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0021] This utility model discloses an organic fertilizer fermentation device.

[0022] Example 1

[0023] According to the appendix Figure 1-5 As shown,

[0024] The tank includes a tank body 1, inside which an air outlet ring block 5 and an agitator 6 are installed. An air outlet ring block 5 has an air duct 52, and a rigid filter screen 54 is installed at the bottom of the air duct 52. The air duct 52 is used to spray gas out of the rigid filter screen 54. The agitator 6 is rotatably connected inside the tank body 1 and includes a fixing ring 62, an upper scraper 63, and a lower scraper 64. The upper scraper 63 is arranged in an array on the fixing ring 62, and there are three sets of upper scraper 63. The upper scraper 63 is slidably connected inside the air duct 52. The upper scraper 63 is used to scrape off the clumps on the top of the hard filter screen 54. The lower scraper 64 is installed at the bottom of the upper scraper 63. The lower scraper 64 is also provided in three sets. The lower scraper 64 is used to scrape off the clumps at the bottom of the hard filter screen 54. An air inlet pipe 4 is fixedly connected to the tank body 1. An air outlet pipe 51 is opened in the air outlet ring block 5. An air outlet nozzle 53 is arrayed at the top of the air duct 52. The air inlet pipe 4 is connected to the air outlet pipe 51. The air outlet pipe 51 is used to deliver gas to the air outlet nozzle 53.

[0025] In use, the output air duct 51 receives airflow from the inlet air duct 4 and blows it into the air duct 52. Since the fixing ring 62 blocks the outer end of the air duct 52, the airflow can only be blown out from the hard filter screen 54 at the bottom. At the same time, the upper scraper plate 63 and the lower scraper plate 64 on the fixing ring 62 scrape the hard filter screen 54 to prevent the hard filter screen 54 from being blocked by dust, which would prevent the airflow from being blown into the tank 1.

[0026] Example 2

[0027] Based on Example 1, according to Appendix Figure 1-5 As shown,

[0028] A lid 2 is installed at the top of the tank body 1, and a motor 3 is installed on the lid 2. The stirring component 6 also includes a rotating shaft 61, which is fixedly connected to the power output end of the motor 3. A fixing ring 62 is fixedly connected to the top of the rotating shaft 61. A fermentation inner tank shell 7 is installed inside the tank body 1. The fermentation inner tank shell 7 is used to hold fermentation raw materials. Shearing protrusions 71 are arranged in an array on the inner wall of the fermentation inner tank shell 7. A crushing plow blade 65 is fixedly connected to the rotating shaft 61. The crushing plow blade 65 is arranged in an array on the rotating shaft 61 and is used to cooperate with the shearing protrusions 71 to shear the agglomerated raw materials.

[0029] The rotation of the crushing plow blade 65 and the stationary state of the shearing convex plate 71 cause the slab material located between them to be crushed by shearing force, preventing the material from solidifying on a large scale.

[0030] Gypsum powder, coal ash, and slag are fed into the tank body 1 through the inlet on the lid 2 and gradually filled into the inner fermentation tank shell 7 for static fermentation. The fermentation time is relatively long, which is used for the large-scale reproduction of microorganisms and the rapid decomposition of organic matter. Oxygen is blown to the raw materials through the air outlet ring 5 to provide the necessary additives for fermentation. The crushing plow blade 65 of the agitator 6 stirs the raw materials to prevent caking. The exhaust gas is blown out from the top lid 2 and collected. The fermented material is collected and discharged from the bottom of the tank body 1.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
