Description

Technical Field

[0001] This utility model relates to the field of organic fertilizer processing, and in particular to a layered fermentation chamber for organic fertilizer. Background Technology

[0002] In the process of organic fertilizer fermentation, the uniformity of oxygen supply and temperature stability of the material are key factors affecting fermentation efficiency and quality. Traditional fermentation devices often use fixed aeration pipes or simple turning methods, which have aeration dead zones that lead to local anaerobic fermentation. Fermentation chambers are often cylindrical structures, resulting in uneven material mixing and poor coarse-fine stratification, which affects the consistency of microbial activity. At the same time, existing devices are often fixed structures, which cannot achieve modular expansion and individual discharge, making cleaning and maintenance difficult.

[0003] Therefore, in order to address the above problems, a layered fermentation chamber for organic fertilizer is now being developed. Utility Model Content

[0017] The following description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0018] A layered fermentation chamber for organic fertilizer, such as Figures 1-4 As shown, the device includes a placement seat 1, a fermentation chamber 2 mounted on top of the placement seat 1, the upper diameter of the fermentation chamber 2 being larger than the lower diameter, and the lower part being able to engage with the upper opening, the bottom of the fermentation chamber 2 having a downwardly concave arc surface structure, an air outlet 3 provided on the upper right side of the fermentation chamber 2, an arc-shaped aeration frame 4 rotatably connected inside the fermentation chamber 2, the arc-shaped aeration frame 4 having multiple air holes, an air inlet 5 provided on the front side of the fermentation chamber 2, a drive motor 6 mounted on the front side of the fermentation chamber 2, the drive motor 6 being located to the left of the air inlet 5, gears 7 mounted on both the output shaft of the drive motor 6 and the arc-shaped aeration frame 4, the two gears 7 meshing with each other, a heat preservation chamber 8 provided on the outside of the fermentation chamber 2, connecting cylinders 9 provided on both the upper and lower sides of the heat preservation chamber 8, the diameter of the lower connecting cylinder 9 port being smaller than the diameter of the upper connecting cylinder 9 port, a protrusion 10 provided on the placement seat 1, the lower connecting cylinder 9 port being able to engage with the protrusion 10 and the upper connecting cylinder 9 port.

[0019] It should be noted that the organic fertilizer raw materials are fed into the fermentation chamber 2 from the top. Because the chamber adopts a conical structure with a larger upper diameter than lower diameter, the materials naturally stratify under gravity, with coarser particles distributed in the upper layer and finer materials settling in the lower layer. The concave arc-shaped structure at the bottom further guides the materials to gather towards the center, preventing material accumulation at the edges. After fermentation starts, the drive motor 6 drives the gear 7 connected to the arc-shaped aeration frame 4 via the output shaft gear 7, causing the arc-shaped aeration frame 4 to rotate slowly within the chamber. Multiple evenly spaced air holes on the frame connect to the air inlet 5 at the front of the fermentation chamber 2. External air enters the arc-shaped aeration frame 4 through the air inlet 5 and releases oxygen evenly into the material layer through the constantly changing positions of the air holes during rotation, promoting the uniform growth of aerobic microorganisms. During fermentation, the waste gas produced is discharged from the air outlet 3 on the upper right side of the cavity. The heat preservation cavity 8 on the outside of the cavity realizes the vertical stacking of multiple fermentation cavities through the upper and lower connecting cylinders 9. The lower connecting cylinder 9 has a smaller port diameter and is locked with the protrusion 10 on the placement seat 1 to fix the bottom cavity. The lower connecting cylinder 9 of the upper fermentation cavity forms a nested connection with the upper connecting cylinder 9 (with a larger port diameter) of the lower fermentation cavity. The heat preservation cavity 8 effectively reduces the internal heat loss and maintains a suitable fermentation temperature. After the single-layer fermentation is completed, the connecting cylinder 9 can be separated to remove the corresponding fermentation cavity 2 for material discharge or cleaning. The entire system achieves efficiency improvement and energy consumption optimization of organic fertilizer fermentation through the combination of conical layered structure, rotating aeration oxygen supply and modular heat preservation stacking.
