Chemical production reaction kettle

Abstract

The invention discloses a chemical production reaction kettle, relates to the technical field of chemical equipment, and particularly provides a chemical production reaction kettle which comprises a kettle, a heating device and a stirring shaft. A feed opening and a discharge opening are formed in the top and the bottom of the kettle, the heating device is positioned on the upper side of the kettle, the stirring shaft is positioned above the kettle and extends into the kettle, the kettle comprises a jacket, a reaction barrel and a seal cover, the outer surface of the reaction barrel is nestedin the jacket, the seal cover is hinged to the reaction barrel, the heating device comprises an air supply tank, a heating tank and a ventilation ring, the air supply tank is fixedly connected with the seal cover, and the ventilation ring is fixedly connected with the inner side walls of the reaction barrel. The chemical production reaction kettle has the advantages that an axial-flow motor insidethe air supply tank can work, accordingly, axial-flow fan blades can be driven to rotate and can be matched with an air collecting cover, external air can be guided to flow into the reaction barrel,and the problems of possible material mixing of existing reaction kettles in next operation and influence on the chemical production quality due to the fact that a large quantity of cleaning liquid isattached to the inner walls of existing reaction barrels can be effectively solved by the aid of the cleaning liquid.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a reaction kettle for chemical production. Background technique [0002] The broad understanding of the reactor is a container with physical or chemical reactions. Through the structural design and parameter configuration of the container, the heating, evaporation, cooling and low-speed mixing functions required by the process are realized. The reactor is widely used in petroleum, chemical, Rubber, pesticides, dyes, medicine and food, pressure vessels used to complete processes such as vulcanization, nitration, hydrogenation, alkylation, polymerization and condensation, such as reactors, reaction pots, decomposition pots and polymerization kettles; the material is generally carbon Manganese steel, stainless steel, zirconium, nickel base (Hastelloy, Monel, Inconel) alloys and other composite materials. [0003] After the operation of the reactor is completed and the ra...

AI Technical Summary

Problems solved by technology

[0003] After the operation of the reactor is completed and the raw materials are discharged, the reactor needs to be cleaned to facilitate the next operation. After the existing reactor is cleaned, because the inside of the reactor is in a closed state, the internal air flow is slow, and the cleaning liquid will condense into A large number of water droplets adhere to the inner wall of the reaction tank, causing the problem of possible mixing of materials in the next operation of the reactor, which affects the quality of chemical production, and most of the stirring blades of the existing reactor are located in the axis area of ​​the reaction tank, which affects the side wall of the reaction tank. The mixing of raw materials is weak, which affects the efficiency of raw material mixing
