Description

Technical Field

[0001] The utility model relates to the technical field of reaction kettles, in particular to a stirring and lifting device for a reaction kettle. Background Art

[0002] Stirring is the core component of the reactor. When the material mixing reaction is carried out, stirring mainly plays the role of promoting the mutual dissolution of liquids, dispersing incompatible liquids to promote gas-liquid contact, dispersing solid and liquid phases and enhancing heat transfer. The main component of stirring is the impeller. When working, the impeller applies mechanical energy to the liquid with the movement of the rotating shaft, thereby achieving stirring. Commonly used stirring devices are generally directly installed on the flange cover or the head on the shell. When the inside of the shell needs to be cleaned after a long period of operation, the entire stirring device needs to be removed from the reaction vessel. Usually, the flange cover or the head on the shell needs to be lifted by a lifting tool to clean the reaction vessel. The operation is laborious and time-consuming. Frequent disassembly can easily cause stirring deformation and reduce stirring efficiency.

[0003] A Chinese patent discloses a stirring and lifting device for a reactor (authorization announcement number CN219482672U). This patented technology can start a rotating motor when cleaning is needed, thereby driving the rotating screw to rotate, driving the nut to move upward on it, and then driving the guide rod upward through the fixed frame, and then opening the top cover. After lifting the top cover to a suitable distance, the reactor can be cleaned. After cleaning is completed, the rotating motor is started again. At this time, the rotating screw rotates in the opposite direction, thereby driving the top cover downward and closing the top cover. The working process is simple and easy to operate, which greatly improves the cleaning efficiency. However, the above structure drives the top rod to move by the rotating screw, and the rotating screw is located on the side of the top cover, so that the top cover is unevenly stressed. Long-term driving of the top cover to move by the rotating screw will cause looseness between the top cover and the rotating screw. Therefore, a stirring and lifting device for a reactor is provided to solve the problems raised in the above background technology. Summary of the invention
