Description

Technical Field

[0001] This utility model belongs to the field of organic fertilizer production technology, specifically, it relates to a static fermentation device for organic fertilizer using microorganisms. Background Technology

[0002] With the deepening of the concept of sustainable agricultural development, microbial organic fertilizers have gradually become an important input in modern agriculture due to their advantages such as improving soil structure, enhancing soil fertility, and promoting crop growth. Static fermentation, as a commonly used method for the production of microbial organic fertilizers, has advantages such as simple operation and low energy consumption.

[0003] Utility model patent CN220642939U discloses a microbial-based static fermentation device for organic fertilizer in the field of organic fertilizer fermentation technology. The device includes a fermentation tank and an aeration mechanism. A sealing cap is threaded onto the upper opening of the fermentation tank. An exhaust gas outlet pipe is located within the installation port in the center of the sealing cap. An oxygen concentration sensor is located within an opening on the right side of the outer arc surface of the fermentation tank. This microbial-based static fermentation device has a reasonable structural design. When the oxygen concentration is insufficient, a microcontroller controls the opening of the gas valve, allowing oxygen to enter the fermentation tank through a ring-shaped oxygen pipe and an exhaust pipe. The oxygen entering the fermentation tank then enters the organic fertilizer pile to be fermented through a fixed cylinder and a ventilation hole, providing sufficient oxygen supply to the microorganisms. This effectively promotes the decomposition of organic matter during fermentation and accelerates the reproduction and activity of microorganisms.

[0004] However, the aforementioned patents still have the following problems: a large amount of waste gas is generated during the static fermentation process. If the waste gas remains in the fermentation tank for a long time, it will not only inhibit the activity of microorganisms and reduce the fermentation efficiency, but may also have an adverse effect on the quality of the fermented products. Existing equipment may have local temperature problems such as excessively high or low temperatures, which will cause the fermentation process in different areas of the fermentation tank to be inconsistent, affecting the overall fermentation effect. A large amount of residue and dirt will be generated during the use of the fermentation equipment. If it is not cleaned and maintained in time, it will not only affect the normal operation of the equipment and the fermentation effect, but may also contaminate the fermented products. The use of the device is inconvenient.

[0005] In view of this, this utility model is proposed. Utility Model Content
