Description
Technical Field
[0001] The utility model relates to the technical field of mechanical stirrers for biological fermentation tanks, and more specifically, to a mechanical stirrer for biological fermentation tanks. Background Art
[0002] In the existing mechanical agitator technology for biological fermentation tanks, there are still some shortcomings in the design and function realization of the agitator, which may affect the performance and stability of the agitator.
[0003] First of all, the existing mechanical agitators for biological fermentation tanks mainly rely on stirring to promote the reaction. This single stirring method results in slow mixing and reaction rates. During the biological fermentation process, the speed of the mixing and reaction rates directly affects the fermentation efficiency and product quality. Slower mixing and reaction rates will lead to longer fermentation time and reduced production efficiency, which will also affect the quality and output of the product.
[0004] Secondly, most existing agitators use a motor to drive the stirring rod and stirring frame to achieve the stirring function. However, this design has some problems during the stirring process. Since the connection between the motor output end and the stirring rod is relatively simple, when the stirring frame encounters greater resistance or foreign objects are stuck, the stirring rod will be subjected to a greater torque. In this case, the stirring rod is prone to breakage and may even cause motor overload damage. This situation will not only affect production progress, but also require additional maintenance costs and time.
[0005] Furthermore, in order to solve the above-mentioned problems, some existing devices have adopted some mechanisms to realize the protective function. These protective devices can trigger the opening mechanism when the stirring rod is subjected to a large torque, causing the motor to idle, thereby preventing equipment damage. However, this type of protective device cannot flexibly adjust the trigger mechanism according to production needs and process requirements, which means that when it is necessary to adjust the stirring intensity or cope with different production conditions, the protective device may not be able to provide appropriate protection, thereby affecting production efficiency and product quality.
