▎ 摘　　要

NOVELTY - System has a fermentation cylinder (5) whose middle of the lower end is fixedly connected with an electromagnetic valve discharge port (6). The fermentation cylinder upper end is connected with a transmission cover assembly. One side of the lower surface of the transmission cover assembly is provided with a mixing mechanism (9) for mixing work. One end of the mixing mechanism is fixedly connected with the inner wall of one side of the fermentation cylinder and other end is in transmission connection with the transmission cover component. The outer wall of the other side of the fermentation cylinder is provided with a driving mechanism (3). The driving mechanism is in transmission connection with the transmission cover component. The outer wall of the other side of the fermentation cylinder is provided with a protective cover (4). One side of the upper surface of the transmission cover component close to the driving mechanism is provided with a waste gas discharging mechanism (1). USE - The system is useful for producing organic fertilizer. ADVANTAGE - The system ensures raw material transportation and exhaust gas discharge treatment can be carried out intermittently, so the raw materials can be fully stirred and fermented, through the driving mechanism, the L-shaped connecting rod can be rotated intermittently, so the inflow of clean water can be controlled, the nozzle will atomize the clean water, so the photocatalyst plate, graphene adsorption layer and filter screen layer in the exhaust gas discharge mechanism can better adsorb, filter and degrade the exhaust gas. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of system for producing organic fertilizer. 1Waste gas discharging mechanism 3Driving mechanism 4Protective cover 5Fermentation cylinder 6Electromagnetic valve discharge port 9Mixing mechanism
