A reaction kettle with a cooling device

Abstract

The invention discloses a reaction kettle with a cooling device. The reaction kettle comprises a kettle body, a kettle cover and a stirring device, wherein a feeding hole is formed in the upper end of the kettle body; a discharge opening A is formed in the lower end of the kettle body; the stirring device comprises a stirrer A, a transmission device, a shaft seal and a supporting seat; the stirrer A is positioned inside the kettle body; the shaft seal and the supporting seat are positioned on the kettle cover and are connected with the stirrer A by virtue of the transmission device; a thermometer well stretches into the kettle body, and the upper end of the thermometer well is fixedly arranged on the kettle cover; a thermometer is arranged in the thermometer well; the stirrer A comprises a stirring shaft A, an annular guide pipe, a stator and a rotor; the discharge opening A is connected with a tank body in which a chamber is formed by virtue of a guide pipe; and a pipeline and cooling liquid are arranged in the chamber. According to the reaction kettle with the cooling device, provided by the invention, materials can stretch into the bottom of the kettle, so that the mixing effect is improved. Moreover, according to a novel stirring device, bubbles can be reduced during stirring, the full contact among mixtures is maintained, and reaction products can be subjected to forced cooling.

Description

technical field [0001] The invention belongs to the field of mechanical accessories, and relates to a reaction kettle, in particular to a reaction kettle with a cooling device. 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.

Problems solved by technology

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 A can stir evenly. Although the current agitator A can achieve a simple stirring effect, it cannot achieve sufficient agitation, so that the material cannot be fully reacted, which is a waste of time. A good reaction solution cannot be obtained without the material
