[0003] During the use of the existing fertilizer fermentation device, a large amount of gas is generated due to the metabolic activities of microorganisms, resulting in a gradual increase in the internal pressure of the fermentation tank. If the pressure is too high and not released in time, it may damage the structure of the fermentation tank and even cause safety accidents. Content of the Utility Model

[0004] The purpose of the utility model is to provide a fertilizer fermentation device to solve the technical problem that if the internal pressure of the fermentation tank is too high and not released in time in the prior art, it may damage the structure of the fermentation tank and even cause safety accidents.

[0005] The technical problem to be solved by the utility model can be achieved through the following technical solutions: A fertilizer fermentation device includes a tank body, a cover body, a pressure relief mechanism, and a stirring mechanism for stirring the fermentation materials in the tank body. The cover body is cooperatively arranged on the top of the tank body.

Detailed implementation manners

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0023] As Figures 1 to 4 shown, a fertilizer fermentation device includes a tank body 1, a cover body 2, a pressure relief mechanism 3, and a stirring mechanism 4 for stirring the fermented matter in the tank body 1. The cover body 2 is disposed on the top of the tank body 1 in a matching manner. The pressure relief mechanism 3 includes a limit sleeve 31, a sliding valve body 32, and a treatment assembly 35 for treating the fermented exhaust gas. A chute 33 is provided in the limit sleeve 31. The chute 33 is communicated with the cover body 2. The sliding valve body 32 is slidably connected with the chute 33 in a sliding manner. An exhaust port 34 communicated with the chute 33 is provided on the outer side of the limit sleeve 31. The treatment assembly 35 is disposed at the port of the exhaust port 34. An adjustment assembly for adjusting the position of the sliding valve body 32 in the chute 33 is provided in the limit sleeve 31.

[0024] The fermented matter is placed in the tank body 1. Through the regular or continuous stirring of the stirring mechanism 4, the activities of microorganisms are promoted, the decomposition and transformation of organic substances are accelerated, and a large amount of gas is generated at the same time. As the fermentation progresses, the gas in the tank body 1 gradually accumulates and the pressure gradually increases. At this time, under the action of the pressure in the tank body 1, the sliding valve body 32 slides upward along the chute 33 in the limit sleeve 31, and the exhaust port 34 is gradually opened, allowing the excess gas to be discharged, thereby effectively reducing the pressure in the tank. The discharged gas is treated by the treatment assembly 35 disposed at the port of the exhaust port 34 to remove harmful gas components.

[0025] Through the pressure relief mechanism 3, the excessive pressure in the tank is released in a timely manner, effectively preventing the damage of the tank body 1 and safety accidents caused by excessive pressure, and ensuring production safety. A suitable pressure environment is conducive to the growth and metabolic activities of microorganisms, promotes the smooth progress of the fermentation process, and improves the efficiency and quality of fertilizer fermentation.

[0026] Reference Figure 2 and Figure 3 As shown in

[0027] The elastic force of the spring 36 provides a downward basic force for the sliding valve body 32, so that when there is no external pressure, the sliding valve body 32 can be maintained at a relatively low position, thereby closing the exhaust port 34. When the pressure in the tank increases, the pressure will overcome the elastic force of the spring 36 and push the sliding valve body 32 to slide upward to release the pressure.

[0028] By adjusting the position of the limit slide plate 37, the pre-tightening force of the supporting spring 36 can be changed, and further the opening threshold of the sliding valve body 32 under the action of the tank pressure can be adjusted. When it is necessary to increase the upper limit of the tank pressure, the handle 39 can be rotated to move the limit slide plate 37 downward, increasing the compression amount of the supporting spring 36, thereby increasing the pressure required for the sliding valve body 32 to open; conversely, when it is necessary to lower the upper limit of the tank pressure, the limit slide plate 37 is moved upward to reduce the compression amount of the supporting spring 36.

[0029] Through the fine adjustment of the adjustment component, the precise control of the pressure in the tank can be realized, meeting the requirements of different fermentation processes for the pressure environment. Precise pressure control helps to prevent safety accidents caused by excessive or too low pressure, and further improves the safety of the fermentation process.

[0030] Reference Figure 2 and Figure 3 As shown in

[0031] Due to its porous structure and large specific surface area, activated carbon has a strong adsorption capacity. Activated carbon can effectively adsorb harmful gas components in fermentation waste gas, such as sulfides, ammonia, volatile organic compounds, etc., as well as some odor substances, thereby further purifying the discharged gas.

[0032] Reference Figure 4 As shown, in some specific embodiments, the stirring mechanism 4 includes a rotating shaft 41 and a rotating motor 42. The rotating shaft 41 is rotatably connected to the cover body 2. The rotating motor 42 is fixedly arranged on the top of the cover body 2. The output end of the rotating motor 42 is coaxially and fixedly connected to the rotating shaft 41. Stirring blades 43 are fixedly arranged on the outer side of the rotating shaft 41.

[0033] Start the rotating motor 42, and the motor starts to rotate and drives the rotating shaft 41 to rotate together. The stirring blades 43 on the outer side of the rotating shaft 41 rotate with the rotating shaft 41 and start to stir the fermented matter in the tank body 1. During the stirring process, the rotation speed of the rotating motor 42 can be adjusted as needed to achieve the best stirring effect.

[0034] Reference Figure 1 As shown, in some specific embodiments, a discharge port is opened at the bottom of the tank body 1, and an electric control valve 5 is fixedly arranged at the discharge port. When the fermentation of the fermented matter is completed, the fertilizer can be discharged from the discharge port by opening the electric control valve 5.

[0035] To facilitate the understanding of the embodiments of this solution by those skilled in the art, the working principle of the embodiments of this solution will be described below in combination with specific application scenarios:

[0036] In actual use, first, put the organic materials to be fermented (such as agricultural waste, animal manure, etc.) into the tank body 1. Ensure that the cover body 2 of the tank body 1 is correctly installed and sealed to prevent gas leakage during the fermentation process. Start the rotating motor 42, and the motor starts to rotate and drives the rotating shaft 41 and the stirring blades 43 to rotate together. The stirring blades 43 rotate rapidly in the tank body 1, fully mixing the fermented matter and promoting the uniform distribution and metabolic activities of microorganisms. During the stirring process, the rotation speed of the rotating motor 42 can be adjusted according to the properties of the fermented matter and the requirements of the fermentation stage.

[0037] As the stirring continues, microorganisms begin to decompose the organic matter in the fermented matter, generating a large amount of gas. These gases gradually accumulate in the tank body 1, resulting in an increase in the pressure inside the tank. When the pressure inside the tank reaches a certain level, the sliding valve body 32 slides upward along the chute 33 in the limiting sleeve 31 under the action of the pressure, gradually opening the exhaust port 34.

[0038] After the exhaust port 34 is opened, the excess gas in the tank is discharged through the exhaust port 34. The gas first passes through a filter screen to filter out large particles and impurities therein. Subsequently, the gas enters an adsorption layer made of activated carbon, and the activated carbon in the adsorption layer effectively adsorbs harmful gas components and odor substances to purify the discharged gas. The position of the sliding valve body 32 is jointly controlled by the spring 36, the limit sliding plate 37, the lead screw 38 and the handle 39 in the adjustment assembly. By rotating the handle 39 to adjust the position of the limit sliding plate 37, the pre-tightening force of the spring 36 can be changed, thereby adjusting the opening threshold of the sliding valve body 32 to achieve precise control of the pressure in the tank.

[0039] After a period of fermentation, when the fermented material reaches the expected fermentation effect, the stirring is stopped. The electric control valve 5 at the bottom of the tank body 1 is opened, and the fermented fertilizer is discharged from the discharge port for subsequent processing or storage.

[0040] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.

Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model. Any reference signs in the claims should not be regarded as limiting the claimed rights.
