Technical Field

[0001] This utility model relates to the field of fertilizer fermentation technology, specifically to a fermentation mixing device for microbial fertilizer production. Background Technology

[0002] Microbial fertilizers, also known as organic fertilizers, are products that use the life activities of microorganisms to promote specific fertilizer effects in crops. They contain beneficial microorganisms that can improve soil, promote growth, enhance stress resistance, reduce the amount of chemical fertilizers used, and reduce pollution. They can be classified according to function, such as rhizobium fertilizers and nitrogen-fixing bacteria fertilizers. When applying them, attention should be paid to environmental compatibility. They are an important input for green agriculture. During production, microorganisms are needed to ferment the fertilizer. Stirring and mixing are necessary operations during the fermentation process of microbial fertilizers to ensure even distribution of the inoculum and provide sufficient oxygen for microbial fermentation.

[0003] Existing technologies use stirring rods for mixing. While stirring can promote the even distribution of microorganisms due to the fertilizer being piled to a certain height in the fermentation tank, it is difficult to introduce sufficient external air into the interior, thus hindering aerobic respiration for fermentation. Therefore, we propose a fermentation mixing device for microbial fertilizer production. Utility Model Content

By setting up a ring pipe and connecting pipe, it can be driven to rise and fall inside the fermentation tank. During the rising and falling process, it serves to stir and mix the raw materials. The ring pipe and connecting pipe can be connected to compressed air. The air outlet set at the bottom can discharge compressed air into the raw materials when the ring pipe and connecting pipe rise and fall, which is conducive to the aerobic respiration of microorganisms and efficient fermentation, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fermentation mixing device for microbial fertilizer production, comprising a fermentation tank and an upper plate, wherein the upper plate is supported and fixed above the fermentation tank, and an electric actuator is vertically installed on the surface of the upper plate; a hollow frame is fixed to the end of the extended end of the electric actuator, and an air inlet pipe communicating with the interior of the hollow frame is connected to the surface of the hollow frame; two ring pipes are arranged around the outer ring of the hollow frame, and the ring pipes are connected and fixed to each other and to the hollow frame through connecting pipes, and the ring pipes, connecting pipes and the hollow frame are interconnected; and multiple air outlets communicating with the interior of the ring pipes and connecting pipes are evenly arranged at the bottom of the ring pipes and connecting pipes.

[0006] By adopting the above technical solution, the raw materials are stirred and mixed by lifting and lowering the ring pipe and connecting pipe. The ring pipe and connecting pipe are also connected to compressed air. When lifting and stirring, compressed air can be introduced into the organic fertilizer raw materials through the air outlet, which is conducive to the aerobic respiration of microorganisms and improves the fermentation efficiency.

[0007] Optionally, a metal ring is provided in the area between the ring pipes and between the ring pipe and the hollow frame, and the two ends of the metal ring are welded and fixed between adjacent connecting pipes.

[0026] Please see Figure 1-5 This utility model provides a technical solution: a fermentation mixing device for microbial fertilizer production, including a fermentation tank 1. The bottom outer ring of the fermentation tank 1 is supported and fixed with legs, and there are at least three legs to achieve stable support for the fermentation tank 1. The bottom of the fermentation tank 1 is also provided with a discharge pipe 11 that communicates with its interior. In use, a butterfly valve is installed on the discharge pipe 11. The butterfly valve is closed during the fermentation of organic fertilizer and opened when the fermentation is completed to discharge organic fertilizer from the discharge pipe 11. Alternatively, the organic fertilizer can be dug out from above.

[0027] An upper plate 2 is also provided, which is supported and fixed above the fermenter 1. An electric push rod 21 is vertically installed on the surface of the upper plate 2. The protruding end of the electric push rod 21 extends through to the bottom of the upper plate 2. A hollow frame 3 is fixed to the end of the protruding end of the electric push rod 21. An air inlet pipe 33 communicating with the interior of the hollow frame 3 is connected to the surface of the hollow frame 3. Two ring pipes 31 are provided on the outer ring of the hollow frame 3. The ring pipes 31 are connected and fixed to each other and to the hollow frame 3 through connecting pipes 32. The ring pipes 31, connecting pipes 32 and hollow frame 3 are interconnected. Multiple air outlets 4 communicating with the interior of the ring pipes 31 and connecting pipes 32 are evenly provided at the bottom of the ring pipes 31 and connecting pipes 32.

[0028] When the organic fertilizer raw materials are added to the fermentation tank 1 for fermentation, the hollow frame 3, the ring pipe 31, and the connecting pipe 32 are driven into the fermentation tank 1 by the electric push rod 21, and the height is raised and lowered repeatedly. Through this operation, the ring pipe 31, the connecting pipe 32, and the metal ring 34 can be used to stir and mix the raw materials, which is conducive to the uniform distribution of the bacteria and ensures the fermentation effect. The air inlet pipe 33 is also connected to the compressed air supply pipe. During the above operation, compressed air is injected into the ring pipe 31 and the connecting pipe 32 and discharged from the air outlet 4 at the bottom, filling the organic fertilizer raw materials. This allows the organic fertilizer raw materials to be fully circulated with oxygen-containing compressed air, which is conducive to the aerobic respiration of microorganisms to ferment the organic fertilizer raw materials.

[0029] When the air outlet 4 on the surface of the ring pipe 31 and connecting pipe 32 is raised or lowered, organic fertilizer inside the fermentation tank 1 may easily enter the air outlet 4. To avoid this, the air outlet 4 is connected to a screw cap 41 by screwing. An opening 411 is provided in the middle of the surface of the screw cap 41. Two baffles 42 are locked between the screw cap 41 and the end of the air outlet 4. A filter cotton 43 is provided between the two baffles 42 inside the screw cap 41, so that the filter cotton 43 blocks the opening 411. When in use, the filter cotton 43 prevents organic fertilizer raw materials from entering the air outlet 4, and the filter cotton 43 allows the air outlet 4 to exhaust normally. In addition, even if water in the organic fertilizer enters the air outlet 4, it will be blown out again by the airflow. When the screw cap 41 is unscrewed, the baffles 42 and the filter cotton 43 can be removed and replaced.

[0030] Metal rings 34 are provided in the areas between the ring pipes 31 and between the ring pipes 31 and the hollow frame 3. The two ends of the metal rings 34 are welded and fixed between the adjacent connecting pipes 32. The metal rings 34 can increase the agitation density of the raw materials, so that the organic fertilizer raw materials are more fully agitated and mixed by the ring pipes 31, connecting pipes 32 and metal rings 34.

[0031] In use, connect the air inlet pipe 33 to the compressed air supply pipe, install a butterfly valve at the bottom of the discharge pipe 11, and connect the electric actuator 21 to the industrial control computer. First, control the electric actuator 21 to raise the hollow frame 3, the ring pipe 31, and the connecting pipe 32 to a high position, and put the organic fertilizer raw materials into the fermentation tank 1, and evenly sprinkle the inoculum for fermentation. During fermentation, the electric actuator 21 drives the hollow frame 3, the ring pipe 31, and the connecting pipe 32 to extend into the fermentation tank 1 and reciprocate to raise and lower the height. Through this operation, the ring pipe 31, the connecting pipe 32, and the metal ring 34 can be used to stir and mix the raw materials, which is beneficial to the even distribution of inoculum. To ensure even distribution and optimal fermentation, compressed air is supplied to the hollow frame 3 and flows into the connecting pipe 32 and the ring pipe 31 during this operation. It then exits through the air outlet 4 and the opening 411 of the screw cap 41, thus filling the organic fertilizer raw materials. This ensures that the organic fertilizer raw materials are fully infused with oxygen-containing compressed air, which is beneficial for microorganisms to carry out aerobic respiration and ferment the organic fertilizer raw materials. After fermentation, the electric actuator 21 raises the hollow frame 3, ring pipe 31, and connecting pipe 32, opening the butterfly valve to discharge the raw materials from the discharge pipe 11. This also allows for the rinsing of the ring pipe 31, connecting pipe 32, and metal ring 34. Furthermore, the filter cotton 43 ensures normal compressed air discharge while preventing organic fertilizer raw materials from entering the air outlet 4. When the screw cap 41 is unscrewed, the baffle 42 and filter cotton 43 can be removed and the filter cotton 43 replaced.
