Chemical reaction kettle

Abstract

The invention discloses a chemical reaction kettle. The chemical reaction kettle comprises a kettle body, a protection gas source, a gas pump, a gas drying device and a tail gas absorption device. A gas inlet pipe and a gas outlet pipe are connected with the bottom and the top of the kettle body respectively. The gas inlet pipe is sequentially connected with the gas pump, the gas drying device and the protection gas source through a pipeline, a check valve is arranged between the gas drying device and the protection gas source, and the gas outlet pipe is also provided with a check valve. A gas flow control valve is arranged between the gas pump and the gas inlet pipe, and the gas outlet pipe is connected with the tail gas absorption device. A motor is fixedly arranged in the middle of the top of the kettle body and drives a stirring device. The stirring device comprises a stirring shaft and stirring blades, the stirring shaft comprises an upper half shaft and a lower half shaft, and a spring is arranged in a shaft barrel which coaxially and externally sleeves the upper half shaft. The chemical reaction kettle has advantages that an oxygen isolated environment of raw materials is guaranteed, reverse absorption is prevented, uniformity in mixing is realized, reaction rate is increased, reaction effects are improved, and high thoroughness in reaction is achieved.

Description

technical field [0001] The invention relates to a chemical reaction kettle, in particular to a chemical reaction kettle. Background technique [0002] The reaction kettle is a commonly used chemical equipment. Usually, a variety of chemical raw materials are added into the reaction kettle, and the various chemical raw materials are allowed to undergo chemical reactions in the reaction kettle to obtain the desired reaction product. Certain reactants in the prior art can react with substances in the air, such as oxygen. Therefore, chemical reactions that require the reactants to participate in the reaction but do not need oxygen need to be carried out under the condition of isolating the air, so as to avoid the air from affecting the air. The effect of the reaction. [0003] At the same time, most of the mixers in the reaction kettle are equipped with a motor above the kettle body to drive the stirring shaft extending into the mixing tank to rotate and stir.

Problems solved by technology

[0003] At the same time, most of the mixers in the reaction kettle are equipped with a motor above the kettle body to drive the stirring shaft extending into the mixing tank to rotate and stir. This stirring method saves manpower, but during the stirring process, when the stirring volume is large, Stirring shaft stirring is unstable, prone to non-stirring sloshing phenomenon, affecting the quality of stirring, resulting in uneven stirring
