Defoaming reaction vessel

Abstract

The invention relates to a defoaming reaction vessel. The defoaming reaction vessel comprises a vessel body, a vessel cover and a rotating shaft. Thread paddles used for stirring are installed on the rotating shaft. A permanent magnetism block is installed on the upper surface of each thread paddle. A defoaming device is installed in the vessel body. The defoaming device comprises a spacing screen plate and a support. The support is fixed under the spacing screen plate. Elastic air bags are distributed on the lower surface of the spacing screen plate. A blowhole is arranged in the side wall of each elastic air bag. A ferromagnetic plate is installed at the bottom of each elastic air bag. A defoaming screen plate is fixedly installed on each ferromagnetic plate. Each defoaming screen plate can slide up and down along the side wall of the support. The reaction vessel is delicate in structure, is low in cost and can achieve high-efficiency defoaming on the premise of constant voltage, new impurities cannot be introduced, and high-efficiency and stable operation of the reaction is ensured.

Description

technical field [0001] The invention relates to a chemical equipment, in particular to a reaction kettle. Background technique [0002] Reactor, a device used to mix and stir raw materials in a sealed state. The reactor is composed of a kettle body, a kettle cover, a jacket, a stirrer, a transmission device, a shaft seal device, a support, etc.; it has good acid resistance, Alkali resistance, effective impact resistance, and can provide a certain pressure environment; in the actual use process, many reactions are often accompanied by foam, and a large amount of foam will also be generated when stirring some slurries. A defoamer is added inside, but this method will introduce impurities to the reactants and reduce the purity of the raw materials; in order to avoid this phenomenon, some reactors are equipped with screens in the cavity, but the screens are soaked by the reactants. The defoaming effect is greatly reduced, so the defoaming effect is not obvious after a period of...

[0002] Reactor, a device used to mix and stir raw materials in a sealed state. The reactor is composed of a kettle body, a kettle cover, a jacket, a stirrer, a transmission device, a shaft seal device, a support, etc.; it has good acid resistance, Alkali resistance, effective impact resistance, and can provide a certain pressure environment; in the actual use process, many reactions are often accompanied by foam, and a large amount of foam will also be generated when stirring some slurries. A defoamer is added inside, but this method will introduce impurities to the reactants and reduce the purity of the raw materials; in order to avoid this phenomenon, some reactors are equipped with screens in the cavity, but the screens are soaked by the reactants. The defoaming effect is greatly reduced, so the defoaming effect is not obvious after a period of use; in addition, when using the reactor for physical and chemical reactions, the temperature, pressure, mechanical control and other conditions of the reactor need to be controlled within a more precise range inside; part of the reactor has air guide holes inside to blow out the bubbles through the airflow, but this will cause the air pressure in the reactor to change, so it cannot be widely promoted in actual use; at the same time, the above-mentioned defoaming device also has complex structures, high cost defects
