[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] The utility model provides a technical solution:

[0028] See also Figures 1 to 4 A microbial fermentation tank includes a fermentation tank body 1, a sealing cover 2 is sealed and clamped on the top of the fermentation tank body 1, an exhaust pipe 7 is connected to the top of the right side of the fermentation tank body 1, a feed pipe 9 is connected to the center of the right side of the fermentation tank body 1, and a collection pipe 8 is connected to the right side of the bottom of the fermentation tank body 1. A rotating rod 3 is rotatably connected to the inside of the fermentation tank body 1, and a lifting assembly 4 is rotatably connected to the top of the outer surface of the rotating rod 3;

[0029] The lifting assembly 4 includes a lifting plate 41 rotatably connected to the outer surface of the rotating rod 3. First springs 42 are fixedly connected to the left and right sides of the top of the lifting plate 41. Fixed blocks 43 are fixedly connected to the left and right sides of the top of the rotating rod 3. The top of the first spring 42 is fixedly connected to the bottom of the fixed block 43.

[0030] The left and right sides of the top of the lifting plate 41 are fixedly connected to the inside of the first spring 42 with telescopic rods 13. The telescopic ends of the telescopic rods 13 are fixedly connected to the bottom of the fixed block 43. The top outer surface of the rotating rod 3 is provided with an external thread. The lifting plate 41 passes through the rotating rod 3 and is internally provided with an internal thread that matches the size of the external thread.

[0031] The outer surface of the rotating rod 3 is located at the bottom of the lifting plate 41 and is connected to the stirring assembly 5. The stirring assembly 5 includes a stirring rod 51 fixedly connected to the outer surface of the rotating rod 3 located on the lifting plate 41. The stirring rod 51 is fixedly connected to the stirring blade 52 at one end away from the rotating rod 3.

[0032] By adopting the above technical solution, when in use, the fermentation material to be fermented is put into the interior of the fermentation tank body 1 from the feed pipe 9, and the lifting plate 41 is used to limit and protect the top of the fermentation material. When gas is generated during the fermentation process of the fermentation material, the gas pushes the lifting plate 41 to squeeze the first spring 42 and the telescopic rod 13, and then slides and rises on the outer surface of the rotating rod 3. During the lifting process of the lifting plate 41, the setting of the telescopic rod 13 is used to limit the lifting and lowering effect, thereby preventing the lifting plate 41 from using the telescopic rod 13 to limit the lifting and lowering effect during the lifting process, thereby preventing the lifting plate 41 from rotating during the lifting process. At the same time, the lifting plate 41 drives the rotating rod 3 to rotate during the rising process, and the rotation of the rotating rod 3 drives the stirring rod 51 to rotate, and the rotation of the stirring rod 51 drives the stirring blade 52 to rotate. The rotation of the stirring rod 51 and the stirring blade 52 satisfies the effect of rotating exhaust of the fermented material placed inside the fermentation tank body 1, and at the same time satisfies the effect of rotating cleaning of the inner wall of the fermentation tank body 1, so as to avoid the inconvenience of exhausting the gas inside the fermented material, affecting the fermentation of the fermented material and the working efficiency of gas emission. At the same time, a pressure valve is provided on the outer surface of the exhaust pipe 7 near one end of the fermentation tank body 1. When the gas inside the fermentation tank body 1 reaches a certain value during the rotation exhaust process, the pressure valve opens, and the gas is discharged from the inside of the fermentation tank body 1 through the exhaust pipe 7. When the internal pressure of the fermentation tank body 1 drops to a set range, the valve of the pressure valve closes to meet the sealing effect of the fermentation tank body 1, and at the same time, the gas pressure inside the fermentation tank body 1 is always maintained within the set pressure range.

[0033] Specifically, such as Figure 4 As shown, a placement slot 10 is provided at the bottom of the lifting plate 41, and a protective component 6 is clamped inside the placement slot 10;

[0034] The protection assembly 6 includes a protection plate 61 that is snapped into the interior of the placement slot 10. The protection plate 61 has connection slots 12 on both sides. The inner wall of the connection slot 12 is fixedly connected to a second spring 62. The end of the second spring 62 away from the connection slot is fixedly connected to a positioning block 63.

[0035] Positioning holes 11 are provided on both the left and right sides of the placement slot 10 , and the size of the positioning block 63 matches the size of the positioning holes 11 .

[0036] By adopting the above technical solution, the setting of the protective plate 61 is utilized to protect the bottom of the lifting plate 41, thereby preventing the bacteria produced by the fermented material from adhering to the lifting plate 41 for a long time during the fermentation process, and requiring the lifting plate 41 to be disassembled and replaced, thereby affecting the normal use of the lifting plate 41. When the protective plate 61 needs to be disassembled and replaced after being used for a long time, the positioning block 63 is driven to move after the protective plate 61 is disassembled. During the movement, the positioning block 63 is squeezed by the positioning hole 11, and then the positioning block 63 squeezes the second spring 62 and enters the interior of the protective plate 61, and the positioning block 63 is removed from the interior of the lifting plate 41, thereby improving the safety of the lifting plate 41 during use.

[0037] Working principle: when in use, the biological fermentation material to be fermented is put into the interior of the fermentation tank body 1 from the feeding pipe 9, and the sealing cover 2 is used to seal the fermentation tank body 1, and then the setting of the fermentation tank body 1 is used to ferment the biological fermentation material. Gas is generated during the fermentation of the biological fermentation material, and the generation of gas drives the lifting plate 41 to rise and fall. During the lifting process of the lifting plate 41, the first spring 42 and the telescopic rod 13 are squeezed and then slide stably inside the fermentation tank body 1. After the first spring 42 and the telescopic rod 13 are squeezed, the fixed block 43 plays a limiting effect. During the sliding process of the lifting plate 41, the rotating rod 3 is driven to rotate, and the rotation of the rotating rod 3 drives the stirring rod 51 and the stirring blade 52 to rotate. During the rotation of the stirring rod 51, the fermentation material inside the fermentation tank body 1 is stirred. At the same time, the setting of the stirring blade 52 is used to rotate, stir and clean the inner wall of the fermentation tank body 1. During the rotation of the stirring rod 51, the gas generated inside the fermentation material is rotated and discharged by the exhaust pipe 7;

[0038] When the lifting plate 41 protects the top of the fermentation product, the protective plate 61 is snapped into the inside of the placement groove 10. The setting of the protective plate 61 is used to provide safety protection for the lifting plate 41, and at the same time, it has a limit protection effect on the top of the fermentation product. When the protective plate 61 needs to be disassembled and replaced after long-term use, the positioning block 63 is pushed and the second spring 62 is squeezed to enter the inside of the protective plate 61. Then the protective plate 61 is pulled out from the inside of the lifting plate 41, which satisfies the effect of disassembling and replacing the protective plate 61, improves the safety of the lifting plate 41 during use, and uses the collection pipe 8 to discharge and collect the fermentation product after fermentation is completed.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
