Description

Technical Field

[0001] This utility model relates to the field of organic fertilizer fermentation technology, and in particular to a fermentation tank for bio-organic fertilizer. Background Technology

[0002] Organic fertilizer is a carbon-containing material mainly derived from plants and / or animals, applied to the soil to provide nutrients to plants. Common raw materials used in the production of organic fertilizer include manure, animal and plant residues, etc. During the production process, organic fertilizer needs to be fermented through the biological action of aerobic bacteria to remove toxic substances. This is because unfermented manure or animal and plant residues contain a large number of harmful microorganisms such as E. coli and nematodes. Direct application can lead to the spread of pests and diseases, making crops susceptible to disease, polluting the environment, and having adverse effects on human health.

[0003] Currently, the production of organic fertilizers usually requires the use of fermentation tanks to ferment the raw materials. However, existing organic fertilizer fermentation tanks cannot mix the organic fertilizers evenly, resulting in a slow fermentation speed and thus affecting the quality of the organic fertilizers.

[0004] Therefore, in order to address the problems of slow fermentation speed and poor fermentation quality in existing fermenters, a fermenter that can solve the above problems is needed. Utility Model Content

[0029] Example 1: A fermentation tank for bio-organic fertilizer includes a storage tank 1. A cover plate 2 is fixedly connected to the top of the storage tank 1. A rotating shaft 3 is rotatably connected to the middle of the cover plate 2. A first spiral blade 4 is fixedly connected to the outside of the rotating shaft 3. A cylinder 5 is provided outside the first spiral blade 4. The bottom of the cylinder 5 is fixedly connected to the bottom of the inner wall of the storage tank 1. A connecting rod 7 is fixedly connected to the outside of the upper end of the rotating shaft 3. A guide scraper 8 is fixedly connected to the bottom of the connecting rod 7. The outer side of the guide scraper 8 is in close contact with the inner wall of the storage tank 1. The middle section of the connecting rod 7 is rotatably connected to the stirring shaft 9, the outside of the stirring shaft 9 is fixedly connected to the stirring blade 10, the lower side of the cover plate 2 is fixedly connected to the toothed ring 11, the outer side of the toothed ring 11 is meshed with the gear 12, the middle part of the gear 12 is fixedly connected to the upper end of the stirring shaft 9, the upper side of the cover plate 2 is fixedly connected to the first motor 6, the drive end of the first motor 6 is fixedly connected to the upper end of the rotating shaft 3, the lower end of the storage tank 1 is fixedly connected to the fixed ring 23, and the lower side of the fixed ring 23 is fixedly connected to the support leg 24.

[0030] The storage tank 1 is used for organic fertilizer fermentation. The first motor 6 is started, driving the rotating shaft 3 to rotate. The rotating shaft 3 drives the first spiral blade 4 to rotate. The lower end of the cylindrical cylinder 5 has an opening. The first spiral blade 4, through the opening at the lower end of the cylinder 5, moves the raw material at the bottom of the inner wall of the storage tank 1 upwards, and discharges it from the top of the cylinder 5, causing the raw material to tumble. When the rotating shaft 3 drives the first spiral blade 4 to rotate, it drives the guide scraper 8 to rotate via the connecting rod 7. The rotating guide scraper 8 fits tightly against the inner wall of the storage tank 1. This causes the raw materials on the inner edge of the storage tank 1 to move towards the center. When discharging organic fertilizer, the guide scraper 8 can clean the inner wall of the storage tank 1, thus avoiding waste. When the connecting rod 7 drives the guide scraper 8 to rotate, it drives the stirring shaft 9 and stirring blade 10 to rotate around the cylinder 5. Through the cooperation of the gear ring 11 and gear 12, the stirring shaft 9 and stirring blade 10 rotate on their own axis while rotating around the cylinder 5, thereby stirring the raw materials and promoting the mixing of raw materials. This avoids the problem of uneven fermentation between the raw materials in the middle and the raw materials on the outside of the storage tank 1.

[0031] Example 2: A rotating component 19 is installed on the upper left side of the storage tank 1. A feeding cylinder 13 is fixedly connected to the end of the rotating component 19. A hose 14 is fixedly connected to the upper right side of the feeding cylinder 13. The lower end of the hose 14 is fixedly connected to the left end of the cover plate 2. A hopper 15 is fixedly connected to the lower outside of the feeding cylinder 13. A central shaft 16 is rotatably connected to the middle of the feeding cylinder 13. A second spiral blade 17 is fixedly connected to the outer wall of the central shaft 16. The outer wall of the second spiral blade 17 fits tightly against the inner wall of the feeding cylinder 13. A second motor 18 is fixedly connected to the top of the feeding cylinder 13. The drive end of the second motor 18 is fixedly connected to the top of the central shaft 16.

[0032] The hopper 15 is used to temporarily store the raw materials to be fermented. The raw materials inside the hopper 15 enter the interior of the feed cylinder 13 through the opening at the lower end. The second motor 18 is started to drive the central shaft 16 and the second spiral blade 17 to rotate. The rotating second spiral blade 17 drives the raw materials inside the feed cylinder 13 to move upward and enter the interior of the storage tank 1 through the hose 14, thereby increasing the difficulty of raw material storage and improving the efficiency of raw material storage.

[0033] As one of the optimized structural designs for Example 1, such as Figures 1-3 As shown, a fixing plate 20 is fixedly connected to the lower left side of the storage tank 1. An electric push rod 21 is fixedly connected inside the fixing plate 20. A push rod 22 is rotatably connected to the drive end of the electric push rod 21. The end of the push rod 22 is rotatably connected to the right side of the feed cylinder 13.

[0034] The drive end of the electric push rod 21 can move upward, thereby driving the push rod 22 to move upward. At the same time, the push rod 22 rotates to the left, thereby pushing the feeding cylinder 13 to rotate through the rotating part 19, thereby adjusting the angle of the feeding cylinder 13, which can be adjusted according to the needs, thus facilitating feeding.

[0035] Working principle: During fermentation, the raw materials are placed in the hopper 15. The second motor 18 is started, driving the central shaft 16 to rotate. The rotating central shaft 16 drives the second spiral blade 17 to rotate. The rotating second spiral blade 17 moves the raw materials inside the hopper 15 upward and enters the storage tank 1 through the hose 14 for fermentation. The first motor 6 can also be started, driving the rotating shaft 3 to rotate. The rotating shaft 3 drives the first spiral blade 4 to rotate. The rotating first spiral blade 4 can cooperate with the cylinder 5 to move the raw materials at the lower end of the storage tank 1 upward. The raw materials are discharged from the top of the cylinder 5, thereby turning the raw materials and avoiding uneven fermentation. When the rotating shaft 3 drives the first spiral blade 4 to rotate, it drives the guide scraper 8 to rotate through the connecting rod 7. The guide scraper 8 drives the raw materials on the inner edge of the storage tank 1 to move towards the center. When the connecting rod 7 drives the guide scraper 8 to rotate, it drives the stirring shaft 9 to rotate. Through the gear 12 and the gear ring 11, the stirring shaft 9 rotates, thereby driving the stirring blade 10 to rotate, stirring the raw materials, promoting mixing, and avoiding uneven fermentation.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
