Description

Technical Field

[0001] This utility model relates to the field of microbial fertilizer fermentation technology, specifically to a tobacco microbial fertilizer fermentation device. Background Technology

[0002] Microbial fertilizers, also known as bio-fertilizers, inoculants, or microbial fertilizers, are a type of live microbial products that use the life activities and products of microorganisms as a medium to enable crops to obtain specific fertilizer effects. Their application in tobacco cultivation has a very strong advantage, promoting the early and rapid growth of tobacco plants and helping tobacco to open leaves and increase the number of effective leaves.

[0003] In the production process of microbial fertilizers, fermentation devices are required. Existing fermentation devices usually rely on a rotating shaft to drive the stirring blades for simple one-way stirring. The stirring time is long and the stirring is not uniform and thorough enough, resulting in low production efficiency. Furthermore, it is not possible to sample each fermentation zone during stirring, so it is impossible to determine whether to continue stirring or stop stirring based on the fermentation status of the microbial fertilizer, making it inconvenient to use. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a tobacco microbial fertilizer fermentation device that can uniformly and thoroughly stir the microbial fertilizer, improve production efficiency, and facilitate sampling of the microbial fertilizer in each section, thereby making it easier to determine the fermentation status of the microbial fertilizer.

[0005] This utility model is achieved through the following technical solution: a tobacco microbial fertilizer fermentation device, comprising a fermentation tank and a stirring mechanism disposed inside the fermentation tank. A heating coil is fixedly connected to the outer wall of the fermentation tank. The stirring mechanism includes a vertically extending outer rotating shaft and an inner rotating shaft. The outer rotating shaft is hollow and sleeved on the inner rotating shaft. A first stirring part is fixedly disposed on the outer rotating shaft, and a second stirring part is fixedly disposed on the inner rotating shaft. The outer rotating shaft is rotatably connected to the top of the fermentation tank. A support frame is fixedly connected to the top of the fermentation tank. The inner rotating shaft is rotatably connected to the support frame. The support frame is provided with a driving mechanism for driving the outer rotating shaft and the inner rotating shaft to rotate in opposite directions.

[0006] This solution uses heating coils to heat the microbial fertilizer inside the fermentation tank, improving fermentation efficiency. Since the outer shaft is rotatably connected to the fermentation tank and the inner shaft is rotatably connected to the support frame, both shafts can rotate independently. Therefore, the drive mechanism causes the outer and inner shafts to rotate in opposite directions, resulting in the first and second stirring sections rotating in opposite directions. This creates mutual reaction forces between the stirred microbial fertilizer particles, ensuring thorough collision and mixing, leading to more uniform and complete mixing, and further improving production efficiency.

[0007] As an optimization, the drive mechanism includes a drive motor, a driving bevel gear, a driven bevel gear one, and a driven bevel gear two. Driven bevel gear one and driven bevel gear two are vertically distributed and coaxially arranged. The upper part of the inner rotating shaft is fixedly connected to driven bevel gear one, and the upper part of the outer rotating shaft is fixedly connected to driven bevel gear two. The driving bevel gear is fixedly connected to the output end of the drive motor and meshes between driven bevel gear one and driven bevel gear two. In this optimized scheme, the driving bevel gear is driven to rotate by the drive motor, thereby causing the meshing driven bevel gear one and driven bevel gear two to rotate coaxially and in opposite directions. This, in turn, causes the outer and inner rotating shafts to rotate synchronously in opposite directions. A single drive motor can drive both rotating shafts to rotate synchronously, saving energy consumption.

[0008] As an optimization, the outer wall of the fermenter is provided with an insulation layer surrounding the heating coil. This optimization reduces heat loss and enhances the heating effect.

[0009] As an optimization, the first stirring section includes a first horizontal connecting rod and multiple first vertical connecting rods. The first horizontal connecting rod is fixedly connected to the outer wall of the outer rotating shaft, and the multiple first vertical connecting rods are fixedly connected to the first horizontal connecting rod, with the multiple first vertical connecting rods arranged along the length of the first horizontal connecting rod. In this optimized solution, when the outer rotating shaft rotates, the first horizontal connecting rod performs horizontal stirring, and the multiple first vertical connecting rods perform vertical stirring. Through stirring in both horizontal and vertical directions, the stirring effect on the fertilizer is improved.

[0010] As an optimization, the second stirring section includes a second horizontal connecting rod, a second vertical connecting rod, and multiple third horizontal connecting rods. The second horizontal connecting rod is fixedly connected to the outer wall of the inner rotating shaft, the lower end of the second vertical connecting rod is fixedly connected to the second horizontal connecting rod, and the multiple third horizontal connecting rods are fixedly connected to the second vertical connecting rod. The third horizontal connecting rods are located between the second vertical connecting rod and the outer rotating shaft, and are arranged along the length of the second vertical connecting rod. In this optimized scheme, when the inner rotating shaft rotates, the second horizontal connecting rod and the multiple third horizontal connecting rods perform lateral stirring, and the second vertical connecting rod performs vertical stirring, improving the stirring effect on the fertilizer. Combined with the reverse stirring of the first stirring section, the fertilizer forms a swirling flow field effect, greatly improving the stirring uniformity.

[0011] As an optimization, multiple first stirring sections are arranged along the length of the outer rotating shaft, and these multiple first stirring sections are staggered with multiple third horizontal connecting rods. This optimized solution, through the staggered arrangement of multiple first stirring sections and multiple third horizontal connecting rods, creates multiple opposing action zones for the fertilizer from top to bottom during stirring. Within each zone, the fertilizer collides with each other, resulting in more uniform and thorough mixing of the fertilizer.

[0012] As an optimization, a vertically extending sampling tube is provided on one side of the fermenter. A first sampling tube, a second sampling tube, and a third sampling tube are respectively fixed to the upper, middle, and lower parts of the outer wall of the fermenter. All three sampling tubes are connected to the sampling tube and are equipped with a switch valve. A discharge port is located at the bottom of the sampling tube, and a switch valve is also installed on the discharge port. This optimized solution allows for sampling of the upper, middle, and lower sections of the fermenter using the first, second, and third sampling tubes. The discharged fertilizer is discharged through the sampling tube, facilitating the determination of the fermentation state of the microbial fertilizer in each section, making sampling and testing more accurate and convenient to use.

[0013] As an optimization, the sampling tube is equipped with an observation window. This optimization facilitates the observation of the sample volume.

[0014] The beneficial effects of this invention are as follows: heating the microbial fertilizer in the fermenter via a heating coil improves fermentation efficiency. Since the outer rotating shaft is rotatably connected to the fermenter and the inner rotating shaft is rotatably connected to the support frame, both shafts can rotate independently. Therefore, the drive mechanism causes the outer and inner shafts to rotate in opposite directions, resulting in the first and second stirring sections rotating in opposite directions. This creates mutual reaction forces between the stirred microbial fertilizers, ensuring thorough collision and mixing, and further improving production efficiency.

[0015] During stirring, samples can be taken from the upper, middle, and lower sections of the fermenter through the first, second, and third sampling tubes, and collected and discharged through the sampling cylinder. This facilitates the determination of the fermentation status of the microbial fertilizer in each section, making sampling and testing more accurate and convenient to use.

[0022] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to describe the solution.

[0023] like Figures 1-4 As shown, a tobacco microbial fertilizer fermentation device includes a fermentation tank 1 and a stirring mechanism disposed within the fermentation tank 1. In this embodiment, the fermentation tank 1 has a feed inlet 2 at its top, with a flange fixed to the feed inlet 2 for easy connection to other equipment. The fermentation tank 1 has a discharge outlet 7 at its bottom, with a switch valve installed on the discharge outlet 7 for convenient control of the discharge.

[0024] A heating coil 3 is fixed to the outer wall of the fermentation tank 1. The microbial fertilizer is heated through the heating coil 3 to improve fermentation efficiency. Preferably, the outer wall of the fermentation tank 1 is provided with an insulation layer 4 surrounding the heating coil 3 to reduce heat loss and enhance the heating effect.

[0025] The stirring mechanism includes an outer rotating shaft 5 and an inner rotating shaft 6 extending vertically. The outer rotating shaft 5 is hollow and sleeved on the inner rotating shaft 6. A first stirring part 8 is fixed on the outer rotating shaft 5, and a second stirring part 9 is fixed on the inner rotating shaft 6. The outer rotating shaft 5 is rotatably connected to the top of the fermentation tank 1. A support frame 10 is fixedly connected to the top of the fermentation tank 1. The inner rotating shaft 6 is rotatably connected to the support frame 10. The support frame 10 is provided with a driving mechanism that drives the outer rotating shaft 5 and the inner rotating shaft 6 to rotate in opposite directions.

[0026] like Figure 1 As shown, in this embodiment, the outer rotating shaft 5 and the inner rotating shaft 6 are coaxially arranged. The upper end of the outer rotating shaft 5 extends to the outside of the fermentation tank 1, and the outer rotating shaft 5 is rotatably connected to the center of the top of the fermentation tank 1 via a bearing 17. The length of the inner rotating shaft 6 is greater than the length of the outer rotating shaft 5, so that both the upper and lower ends of the inner rotating shaft 6 are located outside the outer rotating shaft 5. The upper end of the inner rotating shaft 6 is rotatably connected to the support frame 10 via a bearing 17. Since the outer rotating shaft is rotatably connected to the fermentation tank, and the inner rotating shaft is rotatably connected to the support frame, the outer rotating shaft and the inner rotating shaft can rotate coaxially without interfering with each other.

[0027] Therefore, the outer rotating shaft 5 and the inner rotating shaft 6 can be driven by the drive mechanism to rotate in opposite directions, thereby causing the first stirring part 8 and the second stirring part 9 to rotate in opposite directions and stir. This causes the stirred microbial fertilizer to form mutual reaction forces, allowing the microbial fertilizer to fully collide and mix, making the stirring more uniform and thorough, and improving production efficiency.

[0028] Specifically, the drive mechanism includes a drive motor 11, a driving bevel gear 18, a driven bevel gear 19, and a driven bevel gear 20. The driven bevel gear 19 and the driven bevel gear 20 are distributed vertically and coaxially. The upper part of the inner rotating shaft 6 is fixedly connected to the driven bevel gear 19, and the upper part of the outer rotating shaft 5 is fixedly connected to the driven bevel gear 20. The driving bevel gear 18 is fixedly connected to the output end of the drive motor 11, and the driving bevel gear 18 is meshed between the driven bevel gear 19 and the driven bevel gear 20.

[0029] like Figure 2 As shown, in this embodiment, the driven bevel gear 20 is fixed to the upper end of the outer rotating shaft 5, and the driven bevel gear 19 is located above the outer rotating shaft 5 and fixed to the inner rotating shaft 6. The teeth of the driven bevel gear 19 and the driven bevel gear 20 are located on the same side and mesh with the teeth of the driving bevel gear 18. The drive motor 11 is fixed to the support frame 10. The drive motor 11 drives the rotation of the driving bevel gear 18, thereby driving the driven bevel gear 19 and the driven bevel gear 20 to rotate synchronously in opposite directions, which in turn causes the outer rotating shaft 5 and the inner rotating shaft 6 to rotate synchronously in opposite directions. The two rotating shafts can be driven to rotate synchronously by one drive motor, saving energy consumption.

[0030] Specifically, the first stirring unit 8 includes a first horizontal connecting rod 81 and a plurality of first vertical connecting rods 82. The first horizontal connecting rod 81 is fixedly connected to the outer wall of the outer rotating shaft 5, and the plurality of first vertical connecting rods 82 are fixedly connected to the first horizontal connecting rod 81, and the plurality of first vertical connecting rods 82 are arranged along the length direction of the first horizontal connecting rod 81. In this embodiment, two first vertical connecting rods 82 are arranged along the length direction of the first horizontal connecting rod 81.

[0031] The second stirring section 9 includes a second horizontal connecting rod 91, a second vertical connecting rod 92, and a plurality of third horizontal connecting rods 93. The second horizontal connecting rod 91 is fixedly connected to the outer wall of the inner rotating shaft 6. The lower end of the second vertical connecting rod 92 is fixedly connected to the second horizontal connecting rod 91. The plurality of third horizontal connecting rods 93 are fixedly connected to the second vertical connecting rod 92. The third horizontal connecting rods 93 are located between the second vertical connecting rod 92 and the outer rotating shaft 5, and the plurality of third horizontal connecting rods 93 are arranged along the length direction of the second vertical connecting rod 92. In this embodiment, the second horizontal connecting rod 91 is fixedly connected to the bottom of the outer wall of the inner rotating shaft 6. Two second stirring sections 9 are symmetrically fixed on both sides of the axial direction of the inner rotating shaft 6, further improving the stirring effect.

[0032] The outer rotating shaft 5 has multiple first stirring parts 8 arranged along its length, and the multiple first stirring parts 8 are staggered with multiple third cross connecting rods 93.

[0033] like Figure 4 As shown, in this embodiment, the second vertical connecting rod 92 has three third horizontal connecting rods 93 arranged along its length. The outer rotating shaft 5 has three first stirring parts 8 arranged along its length, and the three first stirring parts 8 and the three third horizontal connecting rods 93 are staggered vertically.

[0034] like Figure 3 As shown, in this embodiment, three first stirring sections 8 arranged vertically form a stirring group, and four stirring groups are evenly distributed around the outer rotating shaft 5. During stirring, the four stirring groups work in conjunction with two second stirring sections to stir the microbial fertilizer in opposite directions, greatly improving the stirring uniformity and making the stirring more thorough.

[0035] A vertically extending sampling tube 13 is provided on one side of the fermenter 1. A first sampling tube 12, a second sampling tube 14, and a third sampling tube 16 are respectively fixed to the upper, middle, and lower parts of the outer wall of the fermenter 1, and all three sampling tubes are connected to the sampling tube 13. Each of the three sampling tubes is equipped with a switch valve. A discharge port is provided at the bottom of the sampling tube 13, and a switch valve is also installed on the discharge port. Samples can be taken from the upper, middle, and lower sections of the fermenter through the first, second, and third sampling tubes, facilitating the determination of the fermentation state of the microbial fertilizer in each section, making sampling and testing more accurate and convenient to use.

[0036] Preferably, the sampling tube 13 is provided with an observation window 15, which extends along the length of the sampling tube 13 to facilitate observation of the sampling amount.

[0037] Working principle: During use, the heating coil 3 heats the microbial fertilizer in the fermentation tank 1, improving fermentation efficiency. The drive motor 11 drives the active bevel gear 18 to rotate, which in turn drives the driven bevel gears 19 and 20 to rotate synchronously in opposite directions. This, in turn, drives the outer shaft 5 and inner shaft 6 to rotate synchronously in opposite directions, causing the first stirring section 8 and the second stirring section 9 to rotate in opposite directions to stir the microbial fertilizer. The reverse-stirred microbial fertilizer creates mutual reaction forces, resulting in thorough collision and mixing, leading to more uniform and complete stirring and improved production efficiency.

[0038] When sampling is required in the upper section of fermentation tank 1 during stirring, the valve of the first sampling tube 12 can be opened, and the fertilizer will enter the sampling cylinder 13 for collection and be discharged from the discharge port. Similarly, when sampling is required in the middle and lower sections of fermentation tank 1, sampling can be achieved by opening the valves of the second sampling tube 14 and the third sampling tube 16 respectively, which is convenient to use.
