Compound stirring device for kettle

Abstract

The invention discloses a compound stirring device for a kettle, consisting of a shaft, an external hollow screw belt, a pressing propeller, a guide heat-transfer drum and a bottom bearing. When the shaft rotates, the external hollow screw belt of the kettle and the pressing propeller work together to realize the full and fast circulation of the medium under the action of the guide heat-transfer drum, the heat-transfer effect of the internal jacket on the guide heat-transfer drum cooperates with the heat-transfer effect of the external jacket to ensure the uniformity of the medium temperature in the kettle, therefore the compound stirring device for the kettle meets the requirements of fast circulation, large viscosity changing range and high accuracy of the temperature control for the polymerization reaction. The device of the invention has the universality for the bulk polymerization, the solution polymerization, the suspension polymerization and the emulsion polymerization, and meets the requirements of the novel stirring device caused by the new process and new material.

Description

technical field [0001] The present invention is a stirring device for a kettle, more specifically, a composite stirring device for a kettle. Background technique [0002] Mixing equipment is widely used in petrochemical, water treatment, biomedicine, environmental protection, food and beverage, metallurgy, mining and papermaking industries. The stirring equipment is mainly composed of a kettle body, a stirring device and a driving part. The stirring device completes the mass transfer, heat transfer, mixing and other tasks of the process. In the polymerization reaction, the stirring device should promote the rapid mixing of the polymer solution, and should adapt to the viscosity change requirements in the polymerization process system, and should control the temperature of the polymerization system and remove heat. In the existing bulk polymerization, solution polymerization, suspension polymerization and emulsification polymerization, there are great differences in the pro...

AI Technical Summary

Problems solved by technology

In the existing bulk polymerization, solution polymerization, suspension polymerization and emulsification polymerization, there are great differences in the process, and the corresponding stirring devices are also different, and there is no commonality with each other. However, new processes and materials emerge in endlessly, requiring continuous design of new stirring The device meets this need, and the compound stirring device for the kettle is designed to solve this problem.
