Description

Technical Field

[0001] This utility model relates to the field of agricultural waste treatment technology, and in particular to a fermentation device for static composting fermentation to produce organic fertilizer. Background Technology

[0002] Agricultural production generates a large amount of agricultural waste, such as livestock and poultry manure, crop straw, and mushroom residue. If these wastes are not handled properly, they will not only cause a huge waste of resources but also cause serious environmental problems. Therefore, in order to rationally handle a large amount of agricultural waste, it is necessary to pile up and ferment the agricultural waste to transform it into organic fertilizer.

[0003] The existing static composting fermentation device for organic fertilizer heats up slowly, resulting in an excessively long fermentation cycle and low efficiency. After fermentation is completed, the existing static composting fermentation device for organic fertilizer requires a long time to lower the temperature, which is inconvenient for subsequent operations and reduces the practicality of the device.

[0004] An existing patent (publication number: CN213537747U) discloses a static composting fermentation device for organic fertilizer. This utility model facilitates the heating of organic fertilizer in the fermentation chamber from the bottom through the cooperation of water pipes, water tanks, heat pipes and water pumps, thereby improving the fermentation heating effect. Through the cooperation of the first installation chamber, fan and electric heating wire, the temperature inside the main body is further increased, enabling the organic fertilizer to mature quickly, shortening the fermentation time and improving the fermentation efficiency.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, existing static composting fermentation devices for organic fertilizers cannot effectively control the spread of odors or eliminate bacteria. Furthermore, they cannot prevent the entry of external water molecules or the automatic replenishment of oxygen. They also cannot efficiently and accurately monitor the temperature, humidity, and oxygen levels in real time during the fermentation process, and they cannot quickly output the fermented organic fertilizer after fermentation.

[0006] Therefore, a fermentation device for static composting fermentation to produce organic fertilizer is proposed. Utility Model Content

[0030] In this embodiment: by setting up a molecular membrane 3, a monitoring structure 6, an oxygen supply mechanism 7, and an output mechanism 8, the molecular membrane 3 at the top of the fermentation chamber 1 can effectively prevent the spread of odors, improve the surrounding environment and avoid residents' complaints, and also eliminate bacteria to ensure the quality and safety of organic fertilizer. At the same time, it prevents external water molecules from entering to maintain stable humidity in the fermentation chamber 1 and reduce nutrient loss. The monitoring structure 6 can efficiently and accurately monitor parameters such as temperature, humidity, pressure, and oxygen in real time, making it convenient for operators to adjust fermentation conditions and improve resource utilization efficiency. The oxygen generator 701 in the oxygen supply mechanism 7 provides oxygen to the fermentation chamber 1 through the oxygen supply pipe 702 and the three-way pipe 703 to meet the metabolic needs of aerobic microorganisms, improve fermentation efficiency, and shorten the composting cycle. The output mechanism 8 can quickly transport the fermented organic fertilizer out of the fermentation chamber 1 to improve production efficiency for subsequent processing.

[0031] Specifically, such as Figure 5 As shown, the output mechanism 8 includes an arc groove 801 opened on the bottom side inside the fermentation chamber 1, and a motor 802 is bolted to the rear side of the fermentation chamber 1. The output end of the motor 802 passes through the rear side of the fermentation chamber 1.

[0032] Specifically, such as Figure 5 As shown, a spiral conveying blade 803 is bolted to the output end of the motor 802, and the spiral conveying blade 803 is located inside the arc groove 801.

The transmitter 604 is electrically connected to the temperature and humidity sensor 601, pressure sensor 602, and electrochemical oxygen sensor 603, centrally receiving and processing the sensor data. Operators can then use this data to... Accurate data is used to adjust fermentation conditions via control box 9, which is electrically connected to transmitter 604, thereby improving resource utilization efficiency. Oxygen generator 701 provides oxygen to fermentation chamber 1 through oxygen supply pipe 702 and three-way pipe 703. The oxygen is evenly distributed within fermentation chamber 1, meeting the metabolic needs of aerobic microorganisms, thus improving fermentation efficiency and shortening the composting cycle. Once the organic fertilizer fermentation is complete, control box 9 starts motor 802. The output end of motor 802 penetrates the rear side of fermentation chamber 1, and the bolted spiral conveyor blades 803 are located within the arc groove 801 on the bottom side of the fermentation chamber 1. The spiral conveyor blades 803 quickly transport the fermented organic fertilizer to the discharge valve 804 connected to the bottom front side of fermentation chamber 1, achieving rapid output of the organic fertilizer and improving production efficiency for subsequent processing. The synergistic effect of these structures achieves functions such as odor control, bacterial elimination, humidity stabilization, precise monitoring, oxygen supply, and rapid output, providing an efficient and reliable solution for organic fertilizer production.
