Description

An insulated chemical reaction kettle

technical field

The utility model relates to chemical equipment, in particular to a heat-preserving chemical reaction kettle.

Background technique

The reaction kettle is a common equipment in the chemical industry. Its principle is to stir various liquids in the kettle body through the paddle agitator to disperse the materials evenly, so as to fully react. With the development of science and technology, the society continues to improve the quality of chemical products, and The primary factor affecting the quality of chemical products is the reaction equipment, and the reactor is the primary equipment in the reaction equipment. Therefore, in the chemical industry, the quality of the reactor directly affects the product quality. After the reaction, it is difficult to prevent the heat on the surface of the reactor body from being emitted to the medium or the air inside the cavity during the reaction, so after heating the reactor, it is necessary to keep the reactor at a constant temperature for a certain period of time. It is difficult, because the production of certain chemical products that are relatively strict to the reaction temperature will easily lead to a decrease in the purity of the product and an increase in by-products. On the other hand, when more raw materials are put into the reaction kettle and the volume needs to be increased, the flow velocity changes at this time, and the original agitator cannot fully stir, so that the material molecules cannot fully collide, and the reaction effect is low.
