Reaction kettle

Abstract

The invention discloses a reaction kettle. The reaction kettle comprises a kettle body, a kettle cover and a mixing device, wherein a lug boss is arranged on the inner wall of the kettle body, a pressure cover plate is arranged in the kettle body and positioned on the lug boss, a through hole is formed in the center of the pressure cover plate, and a scraping knife is arranged at the lower end surface of the pressure cover plate and close to the inner wall of the kettle body; the mixing device comprises a mixer, a transmission device, a shaft seal and a support, the mixer is positioned in the kettle body, the shaft seal and the support are positioned on the kettle cover and connected with the mixer through the transmission device, and plug holes are funnel-shaped and uniformly formed in the kettle cover; a thermometer sleeve tube extends into the kettle, the upper end of the thermometer is fixed on the kettle cover, and a thermometer is arranged in the thermometer sleeve tube; the mixer comprises a mixing shaft, a ring-shaped guide tube, a stator and a rotor; and diversion battens are radially arranged and circumferentially, uniformly distributed on the inner wall of the kettle body, and extend along the axial direction. The reaction kettle disclosed by the invention can reduce the generation of air bubbles during mixing through the novel mixing device, keeps full contact between mixed materials, and improves the mixing effect.

Description

technical field [0001] The invention relates to the field of mechanical accessories, in particular to a reaction kettle. Background technique [0002] Reactor is one of the essential equipment in the production of chemical industry. As we all know, there are many kinds of reactors, which are widely used in petroleum, chemical industry, food, medicine, pesticide, scientific research and other industries. They are used to complete polymerization, condensation, vulcanization, Reaction equipment for chemical processes such as alkylation and hydrogenation. However, due to the uneven stirring of the reactor, it will directly affect the quality of the product. If you want to achieve the effect of full stirring, you need to prolong the stirring time, which is time-consuming and labor-intensive, and the work efficiency is low. The agitator is an important part in the reaction kettle. The existing agitator adopts a paddle agitator. When working, the material rotates around the shaft...

However, due to the uneven stirring of the reactor, it will directly affect the quality of the product

If you want to achieve the effect of full mixing, you need to prolong the mixing time, which is time-consuming and labor-intensive, and the work efficiency is low

The agitator is an important part in the reaction kettle. The existing agitator adopts a paddle agitator. When working, the material rotates around the shaft, and the radial fluidity of the material from the periphery to the paddle area is poor, and the mixing effect is relatively poor. In addition, The disturbance of the bottom liquid is small, and the mixing effect of this part of the liquid is even worse

Moreover, the traditional agitator will generate a lot of air bubbles when stirring, which will cause part of the mixture to be wrapped in the air bubbles, causing the mixture to not be fully mixed.

Whether the material can fully react depends on whether the agitator can stir evenly. Although the current agitator can achieve simple stirring effect, it cannot achieve sufficient agitation, so that the material cannot be fully reacted, which wastes the material. Can not get a good reaction solution, in order to solve the above technical problems, a new technical solution is provided
