Sealing cover of reaction kettle

Abstract

The invention discloses a sealing cover of a reaction kettle. The sealing cover comprises a door-shaped bracket, a guide rod, an air cylinder A, a cover body, a flexible sealing ring A, a flexible sealing plate, guide columns and a guide column drive mechanism, wherein the guide rod is mounted on the door-shaped bracket through a guide sleeve; 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 guide rod sequentially passes through the cover body, the flexible sealing ring A and the flexible sealing plate from top to bottom; the two guide columns sequentially pass through the cover body, the flexible sealing ring A and the flexible sealing plate from top to bottom; one guide column drive mechanismdrives one guide column to slide up and down in the cover body; the flexible sealing plate is fixedly connected with the guide columns in a sealing mode; and the diameter of the flexible sealing plate is greater than the opening diameter of the top of the kettle body. The sealing cover improves the reaction kettle cover; through the action of the reaction kettle sealing cover, good sealing effectcan be achieved on the reaction kettle, and the sealing effect is good.

Description

technical field [0001] The invention belongs to equipment used in the chemical industry, and in particular relates to a sealing cover for 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 rea...

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.
