Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1-5 A biological fermentation system includes a fermenter 1, a top plate 2 bolted to the top surface of the fermenter 1, a ring 3 fixedly connected to the top surface of the top plate 2, a top cover 4 bolted to the top surface of the ring 3, a connecting plate 5 fixedly connected to the inner wall of the ring 3, a worm gear 6 rotatably connected to the outer surface of the connecting plate 5, a worm wheel 7 driven by the worm gear 6, a hollow rotating rod 8 fixedly connected inside the worm wheel 7, a rotary joint 9 rotatably connected to the top end of the hollow rotating rod 8, a stirring head 10 fixedly connected to the bottom end of the hollow rotating rod 8, stirring blades 11 fixedly connected to the outer surface of the stirring head 10, a linkage rod 12 fixedly connected to the outer surface of the hollow rotating rod 8, a pinion 13 rotatably connected to one end of the linkage rod 12, a gear ring 14 meshing with the pinion 13, a shaft 15 fixedly connected to the bottom surface of the pinion 13, a stirring head 16 fixedly connected to the bottom end of the shaft 15, and a reduction motor 17 mounted on the top surface of the top cover 4.
[0023] Specifically, a feed pipe 18 is fixedly connected to the top surface of the top cover 4, and a discharge valve 19 is installed at the bottom of the fermentation tank 1.
[0024] The advantage is that by feeding the raw materials to be fermented into the fermentation tank 1 through the feed pipe 18, and the discharge valve 19 installed at the bottom of the fermentation tank 1, when the fermentation process is completed and the fermentation products meet the expected requirements, the discharge valve 19 is opened, and the fermentation products can be smoothly discharged from the fermentation tank 1 for subsequent collection, processing and other treatments. The feed pipe 18 and the discharge valve 19 work together to realize the orderly entry and exit of fermentation materials, ensure the smooth progress of the biological fermentation process, and improve the working efficiency and practicality of the entire fermentation system.
[0025] Specifically, the output shaft of the geared motor 17 is connected to a first bevel gear 20, which is meshed with a second bevel gear 21. The end face center of the second bevel gear 21 is fixedly connected to a worm gear 6.
[0026] Specifically, the gear ring 14 is bolted to the top surface of the top plate 2, the outer surface of the hollow rotating rod 8 is rotatably connected to the auxiliary plate 22, one end of the auxiliary plate 22 is rotatably connected to the shaft 15, and the outer surface of the stirring head 16 is fixedly connected to the stirring blade 11.
[0027] The advantage is that when the reduction motor 17 is started, it drives the first bevel gear 20 to rotate, which in turn drives the second bevel gear 21 to rotate. The second bevel gear 21 then drives the worm gear 6 to rotate, which in turn drives the worm wheel 7 to rotate. The worm wheel 7 then drives the hollow rotating rod 8 to rotate, which in turn drives the stirring head 10 and the stirring blades 11 to rotate. Simultaneously, the rotation of the hollow rotating rod 8 also drives the linkage rod 12 to rotate, which in turn drives the pinion gear 13 to rotate. The pinion gear 13, driven by the gear ring 14, also rotates, thus driving the shaft 15 to rotate. At the same time, the shaft 15 can also... The shaft 15 rotates around the hollow rotating rod 8, driving the second stirring head 16 and another set of stirring blades 11 to rotate. The rotation of the first stirring head 10 and the stirring blades 11 can stir the lower layer of materials in the fermenter 1, making them initially mixed. At the same time, the second stirring head 16 and the other set of stirring blades 11 rotate to stir the upper layer of materials in the fermenter 1. The two stirring structures work together, and the stirring range covers the entire interior of the fermenter 1, effectively avoiding differences in the concentration of fermentation substrate, distribution of microorganisms and nutrient composition in different areas of the tank, ensuring the consistency and stability of the fermentation reaction.
[0028] Specifically, the top of the rotary joint 9 is rotatably connected to an air pipe 23, one end of which is connected to an air pump 24, and a pressure relief valve 25 is installed on the top of the top cover 4.
[0029] Specifically, a spiral heating tube 26 is welded to the inner wall of fermenter 1, and a support rod 27 is installed at the bottom of fermenter 1.
[0030] The advantages are that the gas pump 24 is connected to the rotary joint 9 via the gas pipe 23, which can deliver gas to the vicinity of the stirring head 10 through the hollow rotating rod 8, providing the necessary gas, such as oxygen, for the fermentation process, meeting the gas requirements of microbial growth and fermentation reaction, and promoting the fermentation process; while the pressure relief valve 25 is installed at the top of the top cover 4. During the fermentation process, gas will be generated in the tank due to microbial metabolism, which will cause the pressure to rise. When the pressure exceeds the safe range, the pressure relief valve 25 will automatically open to release excess gas and prevent the fermentation tank 1 from being dangerous due to excessive internal pressure; the rotary joint 9 plays a key role in connection and rotation. It not only ensures stable gas transmission between the gas pipe 23 and the hollow rotating rod 8, but also allows the hollow rotating rod 8 to rotate without being restricted by the gas pipe 23; by setting a spiral heating pipe 26 to connect to steam, the heat carried by the steam is transferred to the material in the fermentation tank 1 through the spiral heating pipe 26. If the temperature is too low during the fermentation process, the steam in the spiral heating pipe 26 can release heat to raise the temperature in the fermentation tank 1 and meet the temperature requirements of the fermentation reaction.
[0031] In operation, the raw materials to be fermented are first fed into the fermentation tank 1 through the feed pipe 18. Then, the reduction motor 17 is started, which drives the first bevel gear 20 to rotate. The first bevel gear 20 drives the second bevel gear 21 to rotate, which in turn drives the worm gear 6 to rotate. The worm gear 6 drives the worm wheel 7 to rotate, which in turn drives the hollow rotating rod 8 to rotate. The hollow rotating rod 8 drives the stirring head 10 and the stirring blades 11 to rotate, thus stirring the lower layer of materials in the fermentation tank 1. At the same time, the hollow rotating rod 8 drives the linkage rod 12 to rotate, which in turn drives the pinion 13 to rotate. The pinion 13 rotates under the drive of the gear ring 14, which in turn drives the shaft 15 to rotate, thus driving the stirring... The first two stirring blades 16 and another set of stirring blades 11 rotate to stir the material in the upper layer of the fermentation tank 1. When oxygen or other gases required for fermentation are needed, the gas pump 24 is turned on, and the gas is delivered to the vicinity of the first stirring blade 10 through the gas pipe 23 and the rotary joint 9 via the hollow rotating rod 8 to provide the necessary gas for fermentation. According to the fermentation requirements, steam is introduced through the spiral heating pipe 26 to regulate the temperature inside the fermentation tank 1. During the fermentation process, if the pressure inside the tank exceeds the safe range, the pressure relief valve 25 automatically opens to release the excess gas. When the fermentation process is completed and the fermentation product meets the expected requirements, the discharge valve 19 is opened to discharge the fermentation product from the fermentation tank 1 for subsequent processing.
[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
