Description

Reation kettle that dispersibility is good and difficult wall adhesion

Technical Field

The invention relates to the field of reaction kettles, in particular to a reaction kettle which is good in dispersibility and not easy to adhere to a wall.

Background

The reaction kettle is widely applied to production type users such as petroleum, chemical industry, rubber, pesticides, dyes, medicines, food and the like and various scientific research and experiment projects, and is used for completing technological processes such as hydrolysis, neutralization, crystallization, distillation, evaporation, storage, hydrogenation, alkylation, polymerization, condensation, heating, mixing, constant-temperature reaction and the like, and generally comprises the following components: the kettle body of the conventional reaction kettle is of a cylindrical structure, and four baffles are arranged in the kettle body.

When the viscosity of the fluid is low and the revolution of the stirrer is high, the material can generate centrifugal force along with the rotation of the stirring shaft, so that the liquid level of the material in the center of the stirring shaft is low, and the liquid level of the material close to the inner wall of the reaction kettle is high, which is known as a vortex phenomenon. Baffles may be installed in the tank to eliminate turbulence. Four baffles are typically installed.

However, because the material is blocked by the baffle, only the flow in the up-and-down direction and the direction towards the center of the reaction kettle is generated, so the uniform dispersibility of the material is poor, and when liquid mixing materials are added into the material in the kettle body, the problem of insufficient mixing materials can be generated.
