Fermentation tanks with built-in magnetic stirring structures have wide applications in various fields, such as biopharmaceuticals, food industry, chemical industry, and agriculture. In the biopharmaceutical field, they are used to produce antibiotics and vaccines; in the food industry, they are used to produce fermented foods such as yogurt, soy sauce, and vinegar; in the chemical industry, they are used to produce chemical products such as organic acids and amino acids; and in the agricultural field, they are used to produce microbial fertilizers and biopesticides. However, existing fermentation tanks have poor stirring effects and cannot fully and evenly stir the materials at the bottom, easily causing the materials to settle at the bottom, thus affecting the fermentation quality.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a fermenter with a built-in magnetically controlled stirring structure, comprising a fermenter body, four support legs fixedly installed at equal intervals in a ring at the bottom of the fermenter body, a discharge valve fixedly installed in the middle of the bottom of the fermenter body, a support frame fixedly installed on one side of the top of the fermenter body, a motor fixedly connected to the inner top of the support frame, a feed valve fixedly installed on the upper part of the surface of the fermenter body, several stirring rods provided in the upper part of the interior of the fermenter body, several mixing rods provided in the lower part of the interior of the fermenter body, a transmission component provided at the output end of the motor, the transmission component being connected to the several stirring rods and the several mixing rods, and when the motor is running, power is output to the several stirring rods and the several mixing rods through the transmission component, so that the several stirring rods and the several mixing rods mix and stir the material, and enhance the effect of preventing the material from settling to the bottom.

[0005] Preferably, the transmission assembly includes a first sprocket, which is fixedly installed at the output end of the motor. A transmission gear is fixedly installed at the bottom of the first sprocket. The bottom of the transmission gear is rotatably connected to the top of the fermentation tank body. An external gear ring is meshed with one side of the transmission gear. A magnet ring is fixedly installed inside the external gear ring. A magnetic steel rod is magnetically coupled inside the magnet ring. The top of the magnetic steel rod is rotatably connected to the support frame through a shaft seat. A slip ring is fixedly installed at the bottom of the magnet ring. A groove is formed on the upper surface of the top of the fermentation tank body. The slip ring is slidably installed inside the groove. The bottom of the magnetic steel rod extends into the interior of the fermentation tank body and is fixedly installed with a first rotating rod. The surface of the first rotating rod is fixedly connected to several stirring rods. A first sealing shaft is rotatably installed on the surface of the magnetic steel rod. The first sealing shaft is fixedly installed in the middle of the top of the fermentation tank body.

[0006] Preferably, the surface of the first sprocket is connected to the second sprocket by a chain meshing, the bottom of the second sprocket is fixedly mounted with a shaft, the surface of the shaft is rotatably mounted with three bushings, the three bushings are fixedly connected to the fermenter body by a fixing head, and the bottom of the shaft is fixedly mounted with a first bevel gear.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, the operator puts the material into the interior of the fermentation tank through the feed valve, and then the operator starts the motor to drive the first sprocket to rotate. When the first sprocket rotates, it drives the outer gear ring to rotate through the transmission gear. When the outer gear ring rotates, it drives the magnet ring to rotate. When the magnet ring rotates, it drives the slip ring to rotate along the inside of the ring groove, which increases the stability of the magnet ring when rotating. When the magnet ring rotates, it causes the magnetic steel rod to rotate along the shaft seat and the first sealing shaft through magnetic coupling. When the magnetic steel rod rotates, it drives several stirring rods to rotate through the first rotating rod, thereby effectively stirring the material.

[0009] While the first sprocket rotates, it drives the second sprocket to rotate via a chain. The rotation of the second sprocket causes the shaft to rotate inside the three bushings. The rotation of the shaft, in turn, drives the second bevel gear via the first bevel gear. The rotation of the second bevel gear, in turn, drives the second rotating rod to rotate along the second sealing shaft. The rotation of the second rotating rod, in turn, drives several mixing rods to mix and stir the material at the bottom, thus preventing material from settling. This results in excellent stirring performance in the fermenter, ensuring thorough and uniform mixing of the material at the bottom and preventing settling, thereby improving fermentation quality.
