AI Technical Summary

Technical Problem

In existing sodium methoxide preparation devices, material tends to accumulate in the dead corners of the conical guide plate, making it difficult to completely empty the container. Furthermore, the mixing uniformity is poor, the dissolution efficiency is low, and there are potential safety hazards.

Method used

Dry nitrogen is introduced from a nitrogen cylinder via a gas pump. Fine bubbles are evenly emitted from the bottom of the reaction vessel through a fine nozzle, forming a micro-jet disturbance dead zone. Combined with a pressure balance system and mechanical stirring, self-cleaning and venting are achieved, ensuring uniform mixing and heating.

Benefits of technology

This technology enables rapid solid-liquid mixing, improves product purity, shortens reaction time, eliminates the need for manual cleaning, and enhances safety and efficiency.

Abstract

The utility model discloses a kind of stirring devices for preparing sodium methoxide, comprising: reaction bucket, the side of the reaction bucket is equipped with nitrogen input assembly, the nitrogen input assembly includes, nitrogen cylinder is detachably installed in the side of the reaction bucket;The above device is sent into annular water pipe by nitrogen cylinder through gas pump with dry nitrogen, and uniform fine bubbles are emitted in the bottom of reaction bucket by multiple groups of fine spray head;Bubble rolls along the surface of conical guide plate and forms microjet, continuously disturbs edge dead angle, and the wet material particles accumulated are rolled into mainstream and pushed to central discharge port. At the same time, top air pressure balance top cover is extracted in real time through air pressure circulation pipe, and after drying through water vapor remover, it flows back, air pressure gauge and air pressure balancer maintain micro-positive pressure, avoid air backflow. Fine bubbles and mechanical stirring jointly act, so that solid-liquid is quickly mixed and uniformly heated, reaction time is shortened, product purity is improved, and whole process does not need to open cover and manual cleaning, safe and efficient.
