Description

Technical Field

[0001] The utility model relates to the technical field of stirring equipment, in particular to a multi-shaft stirring device. Background Technique

[0002] Chemical stirring equipment is usually very large. When designing, it is necessary to consider how to achieve uniform stirring, save energy, and simplify the design as much as possible to reduce costs. At present, the existing multi-shaft stirring devices have achieved uniform stirring of large stirring kettles, but the defect is that multiple driving mechanisms are often required to drive multiple shafts, which not only increases energy waste, but also increases the complexity of the structure and cost due to the added driving mechanisms and shaft seals. Moreover, during the stirring process of the stirring kettle, materials will inevitably adhere to the inner wall. The existing stirring kettles cannot use the driving mechanism to scrape the attachments on the inner wall of the stirring kettle, reducing the applicability of the device body. Therefore, it is necessary to improve the existing device to meet the actual needs. Content of the Utility Model
