Technical Field

[0001] This utility model relates to the technical field of fermentation devices, and in particular to a fermentation device that facilitates stirring of fermentation broth. Background Technology

[0002] Fermentation broth stirring refers to the operation of mixing and promoting the flow of fermentation broth through mechanical or gas-based means during fermentation. Its purpose is to form a uniform material distribution within the fermenter, optimize dissolved oxygen transfer, heat exchange, and nutrient uniformity, prevent stratification or sedimentation of the fermentation broth, and provide favorable environmental conditions for the metabolic activities of microorganisms or enzymes, thereby improving fermentation efficiency and product quality. Existing fermentation broth stirring devices have unique equipment. Although technology continues to develop, the requirements for corresponding devices are becoming increasingly higher. Therefore, there is a particular need for a fermentation device that facilitates stirring of fermentation broth.

[0003] However, while existing fermentation devices that facilitate stirring of the fermentation broth can quickly stir the broth during use, some solid particles in the broth will adhere to the inner wall of the tank during the stirring process. These particles cannot be quickly cleaned by the aforementioned mechanisms, thus affecting the stirring effect of the fermentation broth.

[0004] To address the aforementioned issues, a search revealed a patent with publication number CN219342124U, which discloses a fermentation device for facilitating the stirring of fermentation broth. The patent states that it "includes a fermentation tank, inside which a stirring assembly is rotatably mounted. The stirring assembly includes a central column, and several layers of side plates arranged in a linear array vertically are fixedly connected to the outer side of the central column, with each layer including several side plates arranged in a ring array. A drive motor is bolted to the top of the fermentation tank, and the output shaft of the drive motor passes through the top cover of the fermentation tank and is connected to the stirring assembly for transmission and rotation. A conveying pipe is provided on the outside of the fermentation tank, with its outlet at the top penetrating the side wall of the fermentation tank. This invention achieves rapid stirring and mixing of the fermentation broth by continuously stirring the fermentation raw materials while circulating them." While this mechanism can rapidly stir the fermentation broth during use, some solid particles in the broth will adhere to the inner wall of the tank during the stirring process. This mechanism cannot quickly clean these particles, thus affecting the stirring effect.

[0005] In light of this, in-depth research into the aforementioned issues led to the creation of this case. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0024] Please see Figure 1-5The present invention provides a technical solution: a fermentation device for easy stirring of fermentation liquid, including a tank 1 and a stirring mechanism 2, wherein the stirring mechanism 2 is provided on one side of the surface of the tank 1 and a disassembly mechanism 3 is provided at one end of the tank 1;

[0025] The stirring mechanism 2 includes a first threaded groove 201, a mounting groove 202, a support plate 203, a feed pipe 204, a protective cover 205, a motor 206, a rotating rod 207, a scraper 208, and a stirring blade 209. The first threaded groove 201 and the mounting groove 202 are both located on one side of the surface of the tank 1. The support plate 203 is fixedly connected to the inner wall of the tank 1. The feed pipe 204 and the protective cover 205 are threadedly connected to the inside of the first threaded groove 201. The inside of the mounting groove 202 is fitted into the output end of the motor 206. The output end of the motor 206 is connected to the rotating rod 207. The scraper 208 and the stirring blade 209 are fixedly connected to the surface of the rotating rod 207. The stirring mechanism 209 is connected via the first threaded groove 201, the mounting groove 202, and the support plate 203. The feed pipe 204, protective cover 205, motor 206, rotating rod 207, scraper 208, and stirring blade 209 are configured as follows: First, unscrew the protective cover 205 and connect the feed pipe 204 to the first threaded groove 201. Then, input the fermentation liquid into the tank 1. Next, start the motor 206. The motor 206 drives the rotating rod 207 to rotate through its output end. The two ends of the rotating rod 207 are respectively fitted into the mounting groove 202 and the support plate 203, thereby achieving stable rotational movement. At the same time, the scraper 208 and stirring blade 209 are fixedly connected to the surface of the rotating rod 207. The scraper 208 is in contact with the inner wall of the tank 1 to scrape off the material adhering to the tank wall and avoid residue. The stirring blade 209 is located inside the scraper 208, with a total of four sets arranged in a staggered manner to efficiently stir the material in the tank 1.

[0026] Furthermore, two sets of first threaded grooves 201 are provided, and the two sets of first threaded grooves 201 are symmetrically distributed on the surface of the tank body 1. Through the setting of the first threaded grooves 201, the first threaded grooves 201 are connected to the feed pipe 204 through the threaded structure, so that the feed pipe 204 can be firmly installed on the surface of the tank body 1. In this way, during the feeding process, the feed pipe 204 will not loosen or fall off, ensuring that the material smoothly enters the interior of the tank body 1. At the same time, the first threaded grooves 201 are also threadedly connected to the protective cover 205. When the feeding is finished or the equipment is temporarily not working, the protective cover 205 can seal the feed port to prevent external impurities or foreign objects from entering the tank body 1, ensuring the cleanliness and safety of the material inside the tank body 1.

[0027] Furthermore, one side of the rotating rod 207 is fitted inside the mounting groove 202, and the other side of the rotating rod 207 is supported on the support plate 203. Through the setting of the rotating rod 207, the rotating rod 207 is driven by the output end of the motor 206. As the core component of power transmission, it transmits the rotational motion of the motor 206 to the scraper 208 and the stirring blade 209, so as to realize the normal operation of the stirring mechanism 2. At the same time, one end of the rotating rod 207 is fitted into the mounting groove 202, and the other end is supported on the support plate 203, forming a stable rotational support structure. Its stability ensures that the scraper 208 and the stirring blade 209 do not shake or deviate when rotating at high speed.

[0028] Furthermore, the rotating rod 207 forms a mutually rotating structure with the support plate 203 via the motor 206. The scraper 208 and the stirring blade 209 achieve synchronous rotation via the rotating rod 207 and the motor 206. With the motor 206, the motor 206 is the core power device of the stirring mechanism 2. Its output end provides rotational power to the rotating rod 207, enabling the stirring blade 209 and the scraper 208 to work at a certain speed and in a stable state.

[0029] Furthermore, one side of the scraper 208 is in contact with the inner wall of the tank 1. Two sets of scrapers 208 are provided. Through the arrangement of the scrapers 208, the scrapers 208 are in close contact with the inner wall of the tank 1. They rotate under the drive of the rotating rod 207 to scrape off the material adhering to the tank wall, prevent material residue, improve mixing efficiency and material utilization. At the same time, the scrapers 208 scrape off the material on the tank wall and push it back into the mixing zone, which complements the function of the stirring blades 209, ensuring that the material is fully mixed inside the tank 1 and avoiding uneven mixing or dead corners.

[0030] Furthermore, the stirring blades 209 are arranged inside the scraper 208. The scraper 208 and the stirring blades 209 are staggered on the rotating rod 207. There are four sets of stirring blades 209. Through the arrangement of the stirring blades 209, the stirring blades 209 rotate under the drive of the rotating rod 207, directly applying stirring force to the material in the tank 1, so that the material is fully mixed in the tank 1, avoiding stratification and agglomeration, and ensuring uniform mixing. At the same time, the stirring blades 209 are located inside the scraper 208 and are staggered with the scraper 208. The scraper 208 is responsible for scraping the material on the tank wall back to the mixing zone, and the stirring blades 209 further mix these materials, thereby realizing the circulation and stirring of the material and avoiding the occurrence of mixing dead zones.

[0031] Furthermore, the disassembly mechanism 3 includes a support base 301, a second threaded groove 302, a glass discharge hopper 303, a fixing bolt 304, a third threaded groove 305, and a storage box 306. The support base 301 is attached to the other side of the tank body 1. A second threaded groove 302 is formed on one side of the surface of the support base 301. The glass discharge hopper 303 is fixedly connected to the other side of the support base 301. A fixing bolt 304 is threaded into the second threaded groove 302. A third threaded groove 305 is formed on the other side of the glass discharge hopper 303. The storage box 306 is threaded into the third threaded groove 305. The disassembly mechanism 3, via the support base 301, the second threaded groove 302, a glass discharge hopper 303, a fixing bolt 304, a third threaded groove 305, and a storage box 306, allows for disassembly. The tank 1 is equipped with a disassembly mechanism 3 at the other end of the tank body 1, consisting of a second threaded groove 302, a glass discharge hopper 303, a fixing bolt 304, a third threaded groove 305, and a storage box 306. When the material is discharged, the glass discharge hopper 303 serves as a connecting channel to transport the material in the tank body 1 to the storage box 306. The threaded connection of the third threaded groove 305 ensures the sealing between the storage box 306 and the glass discharge hopper 303, preventing material leakage. Meanwhile, five sets of second threaded grooves 302 are provided on the support base 301 and are distributed at equal angles. The fixing bolts 304 achieve a firm connection and uniform force distribution, thereby ensuring the stability and reliability of the disassembly mechanism 3.

[0032] Furthermore, five sets of second threaded grooves 302 are provided on the support base 301 and are distributed at equal angles. The support base 301 is fixed to the tank 1 by fixing bolts 304. By setting the fixing bolts 304, the fixing bolts 304 engage with the second threaded grooves 302 on the support base 301 to firmly fix the support base 301 to the other side of the tank 1, ensuring the overall stability of the disassembly mechanism 3. At the same time, the fixing bolts 304 provide a reliable fixing force between the support base 301 and the tank 1, avoiding the support base 301 from loosening due to external forces or equipment vibration, and ensuring the normal operation of the disassembly mechanism 3.

[0033] Working principle: First, unscrew the protective cover 205 and connect the feed pipe 204 to the first threaded groove 201. Then, input the fermentation liquid into the tank 1. Next, start the motor 206. The motor 206 drives the rotating rod 207 to rotate through its output end. The two ends of the rotating rod 207 are respectively fitted into the mounting groove 202 and the support plate 203, thereby achieving stable rotational movement. At the same time, a scraper 208 and a stirring blade 209 are fixedly connected to the surface of the rotating rod 207. The scraper 208 is in contact with the inner wall of the tank 1 to scrape off the material adhering to the tank wall to avoid residue. The stirring blade 209 is located inside the scraper 208. On one side, four sets are arranged in a staggered manner to efficiently stir the material in the tank 1. The other end of the tank 1 is equipped with a disassembly mechanism 3. When the material is discharged, the glass discharge hopper 303 serves as a connecting channel to transport the material in the tank 1 to the storage box 306. The threaded connection of the third threaded groove 305 ensures the sealing between the storage box 306 and the glass discharge hopper 303 to prevent material leakage. At the same time, five sets of the second threaded groove 302 are set on the support base 301 and are distributed at equal angles. The fixing bolts 304 achieve a firm connection and uniform force, thereby ensuring the stability and reliability of the disassembly mechanism 3.
