Description

Technical Field

[0001] This utility model belongs to the technical field of organic fertilizer production equipment, specifically a deodorizing fermentation tank system for organic fertilizer production. Background Technology

[0002] Organic fertilizer is a high-quality fertilizer made from animal and plant residues, livestock and poultry manure, green manure, and biogas residue through fermentation and decomposition. It is rich in various nutrients such as nitrogen, phosphorus, and potassium, and also contains abundant organic matter and beneficial microorganisms. Its effects are significant, improving soil structure, enhancing water and fertilizer retention capacity, increasing soil fertility, and providing crops with a continuous supply of comprehensive nutrients. The most crucial step in organic fertilizer production is fermentation, which produces a large amount of odor, harmful to the environment and workers in the production plant. In the early stages of fermentation, the area should be appropriately open to promote the growth and reproduction of aerobic microorganisms. In the middle and later stages, the covering material should be gradually increased to maintain stable fermentation. Therefore, it is necessary to develop an odor control system adapted to organic fertilizer fermentation to meet this requirement. Utility Model Content

[0021] It should be noted that the top of the fermentation tank 1 has an inward protrusion, the suction pipe 15 is located below the protrusion, and the water spray pipe is located on the protrusion.

[0022] To facilitate control of the flipping, the two ends of the fermentation tank 1 are fixedly connected to the first connecting plate 8, the flipping rod 7 is rotatably connected to the first connecting plate 8, the first motor 17 is fixedly connected to the first connecting plate 8, and the rotating shaft of the first motor 17 passes through the first connecting plate 8 and is fixedly connected to the flipping rod 7.

[0023] It should be noted that the flipping rod 7 is "Π" shaped, and the length of its vertical rod is greater than half the width of the fermentation tank 1.

[0024] To facilitate control of the covering, a second connecting plate 2 is fixedly connected to both ends of one side of the fermentation tank 1. A rotating shaft 4 is rotatably connected inside the second connecting plate 2. A second motor 16 is fixedly connected to the second connecting plate 2. The rotating shaft of the second motor 16 passes through the second connecting plate 2 and is fixedly connected to the rotating shaft 4. A plastic cloth roll 3 is fixedly sleeved on the rotating shaft 4.

[0025] Among them, plastic sheet 6 is rolled on plastic sheet roll 3, and the width and length of plastic sheet 6 are both greater than the width and length of fermentation tank 1.

[0026] To facilitate the reduction of harmful substances and odors in exhaust gas, the exhaust gas treatment system includes an acid washing tower 10 and an alkaline washing tower 12. The suction pipe 15 is connected to the first air pump 9 through an air pipe. The first air pump 9 is connected to the acid washing tower 10. The top of the acid washing tower 10 is connected to a second air pump 11. The second air pump 11 is connected to the alkaline washing tower 12 through an air pipe. The top of the alkaline washing tower 12 is equipped with an exhaust fan 13.

[0027] Both the acid washing tower 10 and the alkali washing tower 12 are equipped with inlets and outlets, and both are equipped with valves.

[0028] It should be noted that the acid solution in the acid washing tower 10 is a dilute sulfuric acid solution, and the acid solution in the alkali washing tower 12 is a sodium hydroxide solution. Both of them have undergone anti-corrosion treatment.

[0029] To facilitate pickling, a first air diffuser plate 18 is provided at the bottom of the pickling tower 10. The air outlet of the first air diffuser plate 18 faces downward, and the first air pump 9 is connected to the first air diffuser plate 18.

[0030] To facilitate alkaline washing, a second air diffuser plate 19 is fixedly connected to the bottom of the alkaline washing tower 12. The air outlet of the second air diffuser plate 19 faces downward. The second air pump 11 is connected to the second air diffuser plate 19. A partition plate 20 is fixedly connected to the middle of the alkaline washing tower 12. The partition plate 20 has ventilation holes. An activated carbon layer 21 is fixedly installed above the partition plate 20. The air inlet of the exhaust fan 13 is located inside the alkaline washing tower 12.

[0032] The water tank 5 is equipped with an inlet and an outlet, and medicines or fermentation liquid can be added to the water tank 5.

[0033] The specific working process of this utility model is as follows:

[0034] During operation, the organic fertilizer raw materials are placed in the fermentation tank 1 to begin fermentation. During the fermentation process, the first air pump 9 is turned on, and the odorous gas is drawn into the acid washing tower 10 and dispersed by the first gas diffuser 18. The gas then enters the acid washing tower 10, where the dilute sulfuric acid solution removes the ammonia gas from the odorous gas. The gas is then drawn into the alkaline washing tower 12 by the second air pump 11 and dispersed by the second gas diffuser 19. The alkaline solution removes the sulfur-containing harmful substances from the gas. The exhaust gas after alkaline washing passes through the baffle 20 and then enters the activated carbon layer 21 for adsorption. Finally, it is discharged by the exhaust fan 13.

[0035] During the fermentation of organic fertilizer, when it is necessary to cover the organic fertilizer, the first motor 17 and the second motor 16 are turned on to rotate the flipping rod 7, which pulls the plastic sheet 6 and covers the fermentation tank 1. When the flipping rod 7 reaches the other side and touches the ground, the second motor 16 is reversed, which causes the rotating shaft 4 to rotate, tightening the plastic sheet 6. Soil or bricks are then used to press the plastic sheet 6 down to promote its fermentation.

[0036] When increased humidity is needed, add water or medicine to water tank 5, and then turn on the water pump so that the water in water tank 5 is sprayed out from the spray pipe 14 to promote fermentation.
