Abstract
The utility model discloses a fermentation tank bottom stirring mechanism, which comprises a stirring shaft, a stirring paddle, a fermentation tank, a mechanical seal, a connecting seat, an upper bearing, a lower bearing, a gear box and a motor, wherein the stirring paddle is arranged on the stirring shaft; the lower end of the stirring shaft sequentially penetrates through the mechanical seal center hole, the upper bearing and the lower bearing from top to bottom in the fermentation tank and is connected with an output shaft of the gear box, and an input shaft of the gear box is connected with an output shaft of the motor. The utility model adds the connecting seat with the upper bearing and the lower bearing, and limits the radial freedom degree of the stirring shaft; the mechanical seal only plays a role in sealing, so that the sealing effect is improved, and the service life is prolonged; the stability of the stirring shaft is enhanced.
Description
Technical Field
The utility model relates to an rabbling mechanism especially relates to a fermentation cylinder bottom rabbling mechanism.
Background
At present, most fermentation tanks adopt the structure shown in figure 2, in the working process, a rotating shaft can swing, so that liquid is not uniformly stirred, and due to the swing of the rotating shaft, a framework oil seal is not circumferential and is not uniformly worn, the seal is easy to lose efficacy, and the liquid is continuously leaked; in fig. 2, the mechanical seal is used as a guide for the shaft, but it does not have a guide function, and instead, the mechanical seal is accelerated to wear, resulting in leakage. Therefore, it is an urgent problem for those skilled in the art to develop a stirring mechanism at the bottom of a fermentation tank.
Disclosure of Invention
The utility model provides a fermentation tank bottom stirring mechanism for solving the defects.
The above object of the present invention is achieved by the following technical solutions: a fermentation tank bottom stirring mechanism comprises a stirring shaft, a stirring paddle, a fermentation tank, a mechanical seal, a connecting seat, a bearing, a gear box and a motor, wherein the stirring paddle is arranged on the stirring shaft; the lower end of the stirring shaft sequentially penetrates through the mechanical seal center hole and the bearing from top to bottom and is connected with an output shaft of the gear box, and an input shaft of the gear box is connected with an output shaft of the motor.
Further, the bearing comprises an upper bearing and a lower bearing, and the upper bearing and the lower bearing are respectively arranged at the upper part and the lower part of the central hole of the connecting seat.
The utility model discloses with prior art's advantage be:
1. a connecting seat with an upper bearing and a lower bearing is added, and the radial freedom degree of the stirring shaft is limited;
2. the mechanical seal only plays a role in sealing, so that the sealing effect is improved, and the service life is prolonged;
3. the stability of the stirring shaft is enhanced.
