Description

Technical Field

[0001] The utility model relates to the technical field of reaction kettles, in particular to a fully stirred reaction kettle. Background Art

[0002] A reactor is a production equipment used for mixed production or chemical reactions of multiple materials. In the material production process in the chemical and pharmaceutical fields, the reactor is usually a device for mixing materials and reacting with the medium. During production, multiple materials are placed in the reactor in sequence, and the temperature of the reactor is controlled to stir and mix until the mixed materials in the reactor reach the predetermined state of the process, and then the mixed materials are released from the reactor. Common reactors often add new raw materials for mixing during the stirring process, which causes the new raw materials to be at the top of the mixed materials for a short period of time during stirring, and cannot be quickly moved to various places in the mixed materials. The stirring blades of the reactor usually rotate in a fixed position and cannot be fully stirred. Utility Model Content
