Description

Technical Field

[0001] The invention relates to the technical field of bio-organic fertilizer fermentation, and in particular to a bio-organic fertilizer fermentation process which is fully in contact with oxygen-enriched air. Background Art

[0002] Bio-organic fertilizer (also called bio-organic fertilizer) is a fertilizer that converts organic waste (such as crop residues, animal manure, food processing by-products, etc.) into fertilizer rich in organic matter and effective nutrients through microbial fermentation technology. Bio-organic fertilizer contains a large amount of humus, which can effectively improve soil structure, enhance soil water retention and air permeability, and enhance soil fertility. Bio-organic fertilizer contains active microorganisms, which can fix nitrogen, decompose organic matter, inhibit pathogens, etc. in the soil, and help promote the healthy growth of plants. It not only provides nutrients for plants, but also improves soil quality and promotes sustainable agricultural development.

[0003] Bio-organic fertilizer fermentation is the process of converting organic waste (such as straw, crop residues, livestock and poultry manure, etc.) into nutrient-rich organic fertilizer through the action of microorganisms. Fermentation can not only effectively treat waste, but also improve the nutrient content and availability of fertilizers.

[0004] When fermenting existing biological organic fertilizers, straw raw materials are added into the fermentation barrel for fermentation. However, due to the lack of a compacting mechanism, there are large gaps between the loose straw raw materials, which causes the fermentation barrel to be filled up quickly and the space of the fermentation barrel cannot be fully utilized. The large gaps between the loose raw materials may cause uneven air flow, affecting the uniform distribution of microorganisms, resulting in uneven fermentation process, and some areas may be lacking in oxygen, affecting the fermentation efficiency. Microbial activity will generate heat during the fermentation process. Compost with large gaps may cause uneven heat distribution, affecting the stability of the compost. Some parts may be overheated or the temperature is too low, affecting the fermentation efficiency.

[0016] A bio-organic fertilizer fermentation process with sufficient contact with oxygen-enriched air comprises the following steps:

[0017] S1, when it is necessary to ferment the bio-organic fertilizer, the raw materials are placed in a feeding hopper, and added into a fermentation tank through the feeding hopper for fermentation;

[0018] S2. While the raw materials are being added, the raw material pressing mechanism can be driven to rotate through the transmission mechanism to compact the loose raw materials;

[0019] S3. When the raw material pressing mechanism rotates, it drives the adjusting mechanism, so that the adjusting mechanism can drive the moving seat to move upward intermittently on the oxygen tube, so that the raw material pressing mechanism moves upward to compact the raw materials that are continuously added;

[0020] S4. During the fermentation process of the raw materials, oxygen is injected into the raw materials in the fermentation tank through the oxygen pipe to improve the growth and reproduction of aerobic microorganisms and accelerate the decomposition of organic matter. At the same time, the raw materials in the fermentation tank can be stirred by the reciprocating and rotating raw material turning rack, which more effectively promotes the contact between oxygen and organic materials during the fermentation process, improves the efficiency of microbial metabolism, and promotes the rapid degradation of organic matter.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] When adding the straw raw material into the fermentation tank, the raw material pressing mechanism is used to realize continuous reciprocating movement through the rotating compacting plate under the action of the extrusion frame and the spring, so as to fully compact the raw material in the fermentation tank, effectively reduce the gaps between the straws, improve the stacking density of the raw materials, optimize the space utilization rate of the fermentation tank, avoid low fermentation efficiency caused by too large gaps, effectively improve the stacking state of the straw raw material in the fermentation tank, and improve the fermentation efficiency. It can not only improve the stacking density of the raw materials, but also improve the air circulation, ensure the uniform distribution of microorganisms and sufficient oxygen supply, so as to promote the smooth progress of the fermentation process;

[0023] At the same time, by setting up the adjustment mechanism, the raw material pressing mechanism can be driven to move up intermittently while the raw material pressing mechanism rotates and presses, so as to compact the raw materials layer by layer, ensuring that each layer of straw raw materials is evenly and fully compacted, which can effectively improve the uniformity and efficiency of the fermentation process, help to gradually fill the fermentation tank, ensure that each layer of straw is fully compacted and air circulated, and avoid excessive compression and uneven fermentation;

[0024] By setting up a transmission mechanism, the raw material pressing mechanism can be driven while the spiral conveying rod rotates to feed the material, thereby realizing the linkage of the device. At the same time, the raw material turning frame that reciprocates and rotates can fully turn the raw materials, change the structure of the raw materials, prevent them from agglomerating, increase the contact area between the raw material surface and the air, avoid the accumulation of raw materials or the formation of airtight areas during the fermentation process, ensure that air and heat are evenly distributed, and improve the fermentation efficiency.

[0044] A bio-organic fertilizer fermentation process with sufficient contact with oxygen-enriched air comprises the following steps:

[0045] S1, when it is necessary to ferment the bio-organic fertilizer, the raw materials are placed in the feeding hopper 3, and added into the fermentation tank 1 through the feeding hopper 3 for fermentation;

[0046] S2. While the raw materials are being added, the transmission mechanism 4 can drive the raw material pressing mechanism 7 to rotate to compact the loose raw materials;

[0047] S3, while the raw material pressing mechanism 7 rotates, it drives the adjusting mechanism 6, so that the adjusting mechanism 6 can drive the moving seat 5 to move upward intermittently on the oxygen tube 2, so that the raw material pressing mechanism 7 moves upward to compact the raw materials that are continuously added;

[0048] S4. During the fermentation process of the raw materials, oxygen is injected into the raw materials in the fermentation tank 1 through the oxygen pipe 2 to improve the growth and reproduction of aerobic microorganisms and accelerate the decomposition of organic matter. At the same time, the raw material turning rack 8 that reciprocates and rotates can stir the raw materials in the fermentation tank 1, which more effectively promotes the contact between oxygen and organic materials during the fermentation process, improves the efficiency of microbial metabolism, and promotes the rapid degradation of organic matter.

[0049] Working principle: When bio-organic fertilizer fermentation is required, the raw materials are placed in the feeding hopper 3, and the motor 302 is used to drive the connected spiral conveying rod 301 to rotate, and the raw materials are added to the fermentation tank 1 for fermentation;

[0052] When the rotating ring 701 rotates, it drives the connected arc-shaped rack 702 to rotate.

[0053] During the fermentation process of the raw materials, oxygen is injected into the raw materials in the fermentation tank 1 through the oxygen pipe 2 by the oxygen pump 201, so as to improve the growth and reproduction of aerobic microorganisms and accelerate the decomposition of organic matter. At the same time, the electric push rod 805 is used to drive the push frame 803 connected to the push-pull rod 804 to move back and forth, so that the push frame 803 can drive the two raw material turning frames 8 to move back and forth. At this time, under the action of the guide head sleeve 801 and the spiral groove 802, the raw material turning frame 8 can rotate while moving, so as to stir the raw materials in the fermentation tank 1, more effectively promote the contact between oxygen and organic materials during the fermentation process, improve the efficiency of microbial metabolism, and promote the rapid degradation of organic matter.
