Reaction kettle

Abstract

The invention discloses a reaction kettle. The reaction kettle comprises a kettle body and a sealing cover, wherein the sealing cover comprises a door-shaped bracket, a guide rod, an air cylinder A, acover body, a flexible sealing ring A, a flexible sealing plate, a guide column and a guide column drive mechanism, wherein the base of the air cylinder A is mounted on the door-shaped bracket; the ejector rod of the air cylinder A is connected with the cover body; the flexible sealing ring A is fixed to the bottom of the cover body; the flexible sealing plate is sealed and fixedly connected withthe guide rod; the guide column sequentially passes through the cover body, the flexible sealing ring A and the flexible sealing plate from top to bottom; one guide column drive mechanism drives oneguide column to slide up and down in the cover body; the flexible sealing plate is fixedly connected with the guide column in a sealing mode; a ring-shaped inner groove is formed in the opening of thetop of the kettle body; and the outer diameter of the ring-shaped inner groove is greater than or equal to the diameter of the flexible sealing plate. The reaction kettle improves the reaction kettlecover; and the reaction kettle sealing cover can seal the reaction kettle very well, so that the sealing effect is good.

Description

technical field [0001] The invention belongs to equipment used in the field of chemical industry, in particular to a reaction kettle. Background technique [0002] The broad understanding of the reaction kettle 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. [0003] Reactors are widely used in petroleum, chemical, rubber, pesticides, dyes, medicines, food, pressure vessels used to complete vulcanization, nitration, hydrogenation, alkylation, polymerization, condensation and other processes, such as reactors, reaction pots, decomposition pots , polymerization kettle, etc.; materials generally include carbon-manganese steel, stainless steel, zirconium, nickel-based (Hastelloy, Monel, Inconel) alloys and other composite materials. [0004] The reactor is a comprehensive reaction vessel, and the s...

And only relying on the sealing of the cover body, the sealing effect is not very good

[0009] 2. It is necessary to manually control the strength mechanism to exert force on the cover body, so that the cover body is pressed against the opening of the reaction kettle, so as to achieve the purpose of sealing. This method is very laborious for the operator, and it relies on the limit convex The action of the platform, the screw and the lock nut will limit the cover on the opening of the reactor. When the pressure in the reactor is high, the reaction force to the limiting boss, the screw and the lock nut will be large. After long-term use It will cause damage to the limit boss, screw and lock nut, and lose the limit function.
