Description

Technical Field

[0001] This utility model belongs to the field of agricultural enzyme fermentation technology, specifically referring to an agricultural enzyme fermentation device. Background Technology

[0002] In modern agricultural production, agricultural enzymes, as a green and environmentally friendly agricultural production material, have received increasing attention due to their advantages such as improving soil structure, promoting crop growth, and enhancing the quality of agricultural products.

[0003] The fermentation process of agricultural enzymes is usually carried out in a fermentation device, which is equipped with a safety valve to directly discharge the gas. However, in actual applications, the fermentation process produces gases containing carbon dioxide, water vapor, volatile organic compounds (VOCs), and ammonia. Direct emission of these gases not only pollutes the environment, but the ammonia and volatile organic compounds (VOCs) may also be harmful to human health. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides an agricultural enzyme fermentation device that effectively solves the problem of direct gas emission and environmental pollution.

[0005] To achieve the above functions, the technical solution adopted by this utility model is as follows: an agricultural enzyme fermentation device, including a fermentation tank, which is provided with a sealing cover at the top and a drain outlet and a slag outlet at the bottom. A stirring device is installed on the sealing cover, and a feed inlet and an exhaust pipe are provided on the sealing cover. A safety exhaust valve is installed on the exhaust pipe, and an annular mounting sleeve is threaded to the outer side of the top of the exhaust pipe.

[0006] The top of the mounting sleeve is provided with an annular groove, and an adsorption mesh plate is pressed into the groove. The adsorption mesh plate is pressed and fixed above by a threaded clamping sleeve. The bottom of the clamping sleeve is provided with a downward annular protruding edge. The protruding edge and the groove cooperate to form a sealing and clamping structure for the adsorption mesh plate.

[0007] Preferably, a filter screen is fixedly installed at the bottom of the fermentation tank for separating the fermentation liquid from the fermentation residue, and the residue outlet and liquid outlet are located above and below the filter screen, respectively.

[0008] Preferably, the adsorption mesh is a multi-layer composite structure, comprising an activated carbon adsorption layer and a zeolite molecular sieve adsorption layer arranged sequentially from top to bottom.

[0009] Preferably, the stirring device includes a stirring motor fixed to the top of the sealing cover and a stirring shaft connected to the output shaft of the motor. The stirring shaft extends into the fermentation tank and is connected to the output end of the stirring motor. The bottom of the stirring shaft is provided with a scraper that is in close contact with the surface of the filter screen plate, and the upper part is provided with several stirring rods.

[0010] Preferably, the scraper is made of flexible rubber, and its bottom is in close contact with the surface of the filter screen.

[0011] The beneficial effects of the above-mentioned structure of this utility model are as follows: by setting a threaded ring mounting sleeve above the exhaust pipe and pressing an adsorption mesh plate into the groove at the top of the mounting sleeve, it can effectively adsorb volatile organic compounds (VOCs) and harmful gases such as ammonia generated during fermentation. At the same time, combined with the gas discharge from the safety valve, the initial purification of fermentation gas is achieved, reducing environmental pollution and harm to human health. Moreover, the adsorption mesh plate is easy to replace. Attached Figure Description

[0018] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The utility model will be further described in detail below with reference to the accompanying drawings.

[0020] like Figure 1-5 As shown, the present invention proposes an agricultural enzyme fermentation device, including a fermentation tank 1, which is provided with a sealing cover 2 at the top, a drain outlet 3 and a slag outlet 4 at the bottom, a stirring device 5 installed on the sealing cover 2, a feed inlet 6 and an exhaust outlet on the sealing cover 2, a safety exhaust valve 8 installed on the exhaust pipe 7, and an annular mounting sleeve 9 threadedly connected to the outer side of the top of the exhaust pipe 7.

[0021] like Figure 4 , 5 As shown, the top of the mounting sleeve 9 is provided with an annular groove 10, and an adsorption mesh plate 11 is pressed into the groove 10. The adsorption mesh plate 11 is a multi-layer composite structure, including an activated carbon adsorption layer and a zeolite molecular sieve adsorption layer arranged sequentially from top to bottom. The adsorption mesh plate 11 is pressed and fixed above by a threaded clamping sleeve 12. The bottom of the clamping sleeve 12 is provided with a downward annular protruding edge 13. The protruding edge 13 cooperates with the groove 10 to form a sealing and clamping structure for the adsorption mesh plate 11.

[0022] like Figure 2 As shown, a filter screen plate 14 is fixedly installed at the bottom of the fermentation tank 1 to separate the fermentation liquid from the fermentation residue. The residue discharge port 4 and the liquid discharge port 3 are located above and below the filter screen plate 14, respectively.

[0023] The stirring device 5 includes a stirring motor 15 fixed to the top of the sealing cover 2 and a stirring shaft 16 connected to the output shaft of the motor. The stirring shaft 16 extends into the fermentation tank 1 and is connected to the output end of the stirring motor 15. The bottom of the stirring shaft 16 is provided with a scraper 17 that is in close contact with the surface of the filter screen plate 14, and the upper part is provided with several stirring rods 18. The stirring motor 15 drives the stirring shaft 16 to rotate, and the stirring rods 18 on the stirring shaft 16 begin to stir the fermentation material. The scraper 17 is made of flexible rubber and has high wear resistance and anti-aging properties. Its bottom is in close contact with the surface of the filter screen plate 14.

[0024] In practical use, open the sealing plug of the feed inlet 6 on the sealing cover 2, mix the prepared fermentation raw materials, such as crop straw, livestock and poultry manure, sugars, etc., in a certain proportion, and slowly pour them into the fermentation tank 1 through the feed inlet 6. After adding, tighten the sealing plug in time to ensure the airtightness of the fermentation tank 1.

[0025] Turn on the power to the stirring motor 15. The stirring motor 15 drives the stirring shaft 16 to rotate, and the stirring rod 18 on the stirring shaft 16 begins to stir the fermentation material. In the initial stage of stirring, the stirring speed can be appropriately increased to ensure that the fermentation material is fully mixed. After stirring for a period of time (about 10-15 minutes), the stirring speed is adjusted to the speed required for normal fermentation and stable stirring is maintained. During the stirring process, the scraper 17 at the bottom of the stirring shaft 16 will rotate close to the surface of the filter screen, effectively preventing the fermentation residue from accumulating and clogging the filter screen, ensuring that the filter screen is unobstructed, and allowing the fermentation liquid to flow smoothly through the filter screen into the lower layer.

[0026] During the fermentation process, the pressure inside the fermentation tank will continuously increase. The safety exhaust valve 8 will release the gas, and the released gas will be purified by the adsorption mesh plate 11 before being discharged.

[0027] After fermentation is complete, open the valve of drain port 3. Under the action of gravity, the fermentation liquid in the lower layer of fermentation tank 1 will be discharged through drain port 3. Use a clean container to collect the fermentation liquid. After the fermentation liquid is discharged, open the valve of slag discharge port 4. With manual assistance or mechanical means (such as using tools to loosen the fermentation slag), the fermentation slag in the upper layer of fermentation tank 1 will be discharged from slag discharge port 4. The collected fermentation slag can be used as organic fertilizer or for other agricultural purposes.

[0028] After a period of use, the adsorption capacity of the adsorption mesh plate 11 for volatile organic compounds (VOCs) and harmful gases such as ammonia will gradually decrease. At this time, the adsorption mesh plate 11 needs to be replaced in time. Unscrew the clamping sleeve 12, take out the old adsorption mesh plate 11, and put the new adsorption mesh plate 11 on top. The old adsorption mesh plate 11 that has been replaced can be treated according to the properties of the adsorbed substances, such as using chemical cleaning, regeneration and other methods to restore its adsorption performance, or it can be treated as solid waste for environmental protection.

[0029] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
