Description
Technical Field
The utility model mainly relates to a sodium valproate reation kettle equipment technical field specifically is a reation kettle condensation reflux device.
Background
The reaction kettle is a comprehensive reaction container, and the structural function and the configuration accessories of the reaction kettle are designed according to reaction conditions. The preset reaction steps can be completed with higher automation degree from the beginning of feeding, reaction and discharging, and the important parameters of temperature, pressure, mechanical control (stirring, blowing and the like), reactant/product concentration and the like in the reaction process are strictly regulated and controlled. The structure of the device is generally composed of a kettle body, a transmission device, a stirring device, a heating device, a cooling device and a sealing device. Can appear the material and be heated by liquid phase becoming gaseous state in some reaction processes, the material under the gaseous state volatilizees easily to can't react again, consequently need install the condensation backward flow ware on reation kettle, through cooling heat transfer, become gaseous state material back to liquid, and during the backward flow goes into reation kettle, continue to react.
The condensation reflux device of the sodium valproate existing reaction kettle is basically the same with the reaction kettle in link through a pipeline, in the reaction process, gaseous materials rise from the reaction kettle to the condensation reflux device, cooled liquid materials flow back to the reaction kettle and all pass through the pipeline, so that the rising gaseous materials are too many easily, the liquid materials and the gaseous materials meet in the pipeline again and exchange heat again, the liquid materials cannot smoothly flow back to the reaction kettle, and after the phenomenon is accumulated for a certain time, a large amount of gaseous and liquid materials are retained in the condensation reflux device, cannot participate in the reaction, are easy to volatilize and waste the materials.
SUMMERY OF THE UTILITY MODEL
In view of the defects in the prior art, the object of the utility model is to provide a reaction kettle condensation reflux device.
In order to solve the technical problem, the utility model discloses a following technical scheme: the utility model provides a reation kettle condensation reflux unit, includes reation kettle, its characterized in that: the reaction kettle is characterized in that a cooling reflux cavity is arranged on the upper portion of the reaction kettle, an air outlet is formed in the center of the upper portion of the reaction kettle, reflux holes are formed in the periphery of the upper portion of the reaction kettle, an exhaust fan is arranged in the air outlet, a flow guide part is arranged on the upper portion of an outlet of the air outlet, a flow distribution groove is formed in the flow guide part, a plurality of rectangular notches are formed in the lower end face of the flow guide part, and a flow guide plate is formed between every two.
