Description

Technical Field

[0001] This utility model relates to the field of fermentation tank agitator technology, and in particular to a high-efficiency defoaming agitator for vitamin B2 fermentation tanks. Background Technology

[0002] In the production of vitamin B2, the fermentation tank is a crucial piece of equipment, and the agitator is one of its core components, its performance directly affecting the efficiency and quality of the fermentation process. Currently, existing vitamin B2 fermentation tanks inevitably generate a significant amount of foam during material agitation due to the inherent characteristics of the materials themselves.

[0003] The generation of these bubbles brings many problems. On the one hand, the foam occupies space inside the fermenter, reducing its effective volume and the loading coefficient, thus affecting production efficiency and preventing the fermenter from fully utilizing its capacity. On the other hand, stable foam hinders oxygen transfer and carbon dioxide removal, which are crucial for the normal metabolism of microorganisms. This leads to a deterioration of the growth and metabolic environment for microorganisms, affecting the fermentation effect of vitamin B2. Therefore, there is an urgent practical need to develop a highly efficient defoaming agitator for vitamin B2 fermenters. Utility Model Content

[0004] The main objective of this invention is to provide a high-efficiency defoaming stirring paddle for vitamin B2 fermentation tanks, which addresses the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A high-efficiency defoaming vitamin B2 fermentation tank agitator includes a rotating shaft with multiple agitator components evenly distributed at the lower end of the shaft. Each agitator component includes an upper crossbar, a lower crossbar, and a defoaming plate. The upper and lower crossbars are parallel and of equal length, with one end fixed to the rotating shaft. The other end of both crossbars is connected to the defoaming plate. The defoaming plate has multiple defoaming holes, each containing a defoaming mesh.

[0006] Furthermore, a vertical bar is provided between the upper and lower horizontal bars, and a serpentine bar is fixed on the vertical bar.

[0007] Furthermore, a helical blade is provided at the lower end of the shaft, and the helical blade is located on the shaft section between the upper and lower crossbars.

[0008] Furthermore, the defoaming net has a cross-shaped mesh surface.

[0009] Furthermore, the number of stirring components is four.

[0010] This invention also includes other components that enable the stirring paddle of the high-efficiency defoaming vitamin B2 fermenter to function properly. These devices or components all employ conventional techniques in the art. Furthermore, devices and components not specified in this invention all employ conventional techniques in the art, such as the rotating shaft mentioned in this application. In specific implementation, appropriate equipment or component models can be selected according to the specific working scenario.

[0011] The working principle of this invention is as follows: During operation, the rotating shaft drives multiple stirring components to operate synchronously. The upper and lower crossbars form a parallel and equal-length support structure, jointly driving the defoaming plate to perform a cutting motion. During rotation, the defoaming plate can initially break up the foam on the surface of the fermentation liquid. The foam enters the defoaming holes and is further divided by the cross-shaped defoaming mesh, achieving a three-dimensional defoaming effect. Simultaneously, the spiral blades at the lower end of the rotating shaft enhance fluid circulation within the tank, and the serpentine rod also helps improve the overall breaking and mixing efficiency.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. Improve defoaming efficiency: The defoaming board is initially cut and then divided into a cross-shaped defoaming mesh to form a three-dimensional defoaming structure, which improves defoaming efficiency and reduces foam accumulation.

[0013] 2. Optimized mixing performance: The serpentine bar between the upper and lower crossbars forms vortex disturbances through its special curved surface structure, which further improves the crushing strength of residual foam and the material mixing efficiency. Attached Figure Description
