Description

Technical Field

[0001] This utility model belongs to the field of biological fermentation tank technology, specifically relating to a biological fermentation tank with stable internal support. Background Technology

[0002] Common fermenters are divided into solid fermenters and liquid fermenters; fermenters are also divided into seed tanks (inoculum fermenters) and fermentation tanks according to their volume and purpose; fermenters are further divided into ventilated fermenters and anaerobic fermenters according to their aerobic requirements.

[0003] A search revealed a bioreactor with internal support and stability, patent publication number CN219792946U. The bioreactor includes a tank body, cooling pipes, a rotating shaft, and multiple sets of stirring rods. Multiple sets of support feet are fixedly connected to the lower wall of the tank body. A protective tube is fitted onto the outer wall of the rotating shaft and rotatably connected to two sets of rotating seats. Multiple sets of fixing rings are installed between the inner wall of the protective tube and the outer wall of the rotating shaft. The stirring rods pass through the protective tube and are threaded to the outer wall of the fixing rings. When the stirring rods are subjected to stirring force, the force is shared by the protective tube, the fixing rings, and the rotating shaft.

[0004] In current technologies, common bio-fermentation tanks have a stirring device inserted into the surface of their cover plates. However, since the stirring shaft lacks an external support structure, the tank structure is relatively weak, and the stirring shaft is prone to tilting when rotating. Therefore, it is necessary to design a bio-fermentation tank with stable internal support to solve the above problems. Utility Model Content

The transmission output end of the drive motor is connected to a stirring shaft via a coupling. A guide assembly is installed on the outside of the stirring shaft, and a support assembly is installed inside the tank body.

[0007] The support assembly includes a reinforcing ring fixedly connected to the inner wall of the tank, support columns circumferentially and equidistantly installed on the inner surface of the reinforcing ring, and a guide ring fixedly connected to the end of the support column.

[0008] Preferably, the guide assembly includes an assembly frame sleeved on the outside of the stirring shaft and fixedly connected, and support rods symmetrically mounted on the outer surface of the assembly frame.
