Multifunctional reaction kettle used for chemical industry production and having circulation function

Abstract

The invention relates to a multifunctional reaction kettle used for chemical industry production and having circulation function. The multifunctional reaction kettle comprises a kettle body, a transmission device, a rack and a rotating shaft, wherein the transmission device is fixed on the top end of the kettle body through the rack, and is connected to the rotating shaft positioned in the kettlebody, the rotating shaft is provided with a stirring device, the stirring device comprises four installing columns symmetrically arranged on the upper portion and the lower portion of the rotating shaft, the installing column is sleeved with a sliding block, the sliding block is connected to the rotating shaft through a spring, the spring sleeve is arranged on the installing column in a sleeved manner, the sliding blocks positioned on the same side of the rotating shaft are fixedly connected to a stirring rod, the stirring rod is uniformly provided with a plurality of stirring blades, the sidewall of the kettle body is provided with a circulation device, and the circulation device comprises a circulation pipeline and a screw pump. According to the present invention, the stirring radius ofthe stirring device can be changed as needed so as to achieve the good mixing effect; and the material can be circulated by using the screw pump, such that the material in the kettle body can be effectively impacted and disturbed so as to further improve the mixing effect.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a multifunctional reaction kettle for chemical production with a circulation function. Background technique [0002] The broad understanding of the reaction kettle is a container with physical or chemical reactions. Through the structural design and parameter configuration of the container, the heating, evaporation, cooling and low-speed mixing functions required by the process are realized. Reactors are widely used in petroleum, chemical, rubber, pesticides, dyes, medicines, food, pressure vessels used to complete vulcanization, nitration, hydrogenation, alkylation, polymerization, condensation and other processes, such as reactors, reaction pots, decomposition pots , polymerization kettle, etc. [0003] The stirring and mixing effect of the reactor in the prior art is relatively poor, resulting in that the mixing between materials cannot meet the requirements, and t...

Problems solved by technology

[0003] The stirring and mixing effect of the reactor in the prior art is relatively poor, resulting in that the mixing between materials cannot meet the requirements, and the reaction effect is relatively poor; in addition, in the actual production process, the environment of the reactor is relatively harsh, and the reactor shell The corrosion on the external surface is also very serious, and the heat insulation effect of the existing reactor can not meet the requirements
