Stirring type reaction kettle

Abstract

The invention discloses a stirring type reaction kettle. The stirring type reaction kettle comprises a barrel body, wherein a stirring shaft is mounted in the barrel body, the top end of the stirring shaft is connected with a motor, the lower end of the stirring shaft is sleeved with a shaft sleeve, 3-4 stirring blades are uniformly distributed on the circumference of the shaft sleeve, the rotating directions of the root parts of the stirring blades are inclined for 30-45 degrees relative to the axial direction of the shaft sleeve, and the width of each stirring blade is gradually reduced from the root part to the tip; the reaction kettle further comprises a guide cover arranged on the stirring shaft in a sleeving manner, the upper part of the guide cover is in a hollow barrel shape, the diameter of the lower part is gradually increased, the top of the guide cover is clamped and fixed at the upper part of the stirring shaft, the lower part of the guide cover is open and is not contacted with the bottom wall of the barrel body, multiple guide holes are formed in the upper part of the guide cover, and the upper edge of each guide hole bulges and extends outwards to form a downwards inclined guide cap. According to the stirring type reaction kettle, the reaction materials can be circularly crushed in a large range and have the contact reaction, accordingly, solid-liquid or liquid-liquid reactions are more rapid and more uniform, and the reaction rate and the yield are both increased.

Description

technical field [0001] The invention relates to a stirred reactor. Background technique [0002] A stirred reactor is the most commonly used equipment in chemical production, which generally includes a container, a stirring device placed in the middle of the container and a baffle vertically arranged on the inner wall of the container. When the stirring device rotates, the material in the container rotates around the axis with the impeller of the stirring device, the liquid level in the center partly drops, and the free surface becomes a parabola to form a vortex. The baffle installed vertically on the inner wall of the container can change the flow pattern of the fluid movement, resulting in changes in the flow pattern, velocity and direction of the material in the container, thereby controlling the flow pattern and enhancing the stirring effect. [0003] In order to increase the stirring effect, the existing reactor is realized by changing the shape of the stirring blade ...

AI Technical Summary

Problems solved by technology

[0003] In order to increase the stirring effect, the existing reactor is realized by changing the shape of the stirring blade or adding a baffle on the inner wall of the reactor vessel, but for the mixed reaction system of solid particles and liquid or viscous fluid, the above-mentioned stirred reactor cannot achieve good mixing effect
