[0002] Sludge fermentation treatment to produce organic fertilizer not only protects the environment, but also improves the soil, increases its fertility, increases crop yields, reduces the use of chemical fertilizers, and has multiple benefits. At the same time, using aerobic fermentation technology to produce organic fertilizers that can meet non-agricultural uses from the sludge generated during the sludge treatment process is an effective measure to effectively solve urban sewage sludge. And during the process of making organic fertilizers, special devices are required.

[0003] For example, a device for preparing organic fertilizer by sludge fermentation with the patent publication number CN216764743U includes an outer box. A fermentation inner box is fixedly connected to the inner bottom wall of the outer box. A slideway is fixedly connected to the top of the fermentation inner box.
