A reaction kettle with a sealed heat preservation mechanism

Abstract

The invention relates to a reaction kettle with a sealing and heat preservation mechanism, which comprises a reaction kettle body. There is an upper sealing flange, and a sealing assembly is arranged in the reaction kettle body. The sealing assembly includes a disc-shaped support part and a sealing part arranged on the edge of the support part. The sealing part has an upper extrusion sealing surface and a lower extrusion sealing surface , the inner side of the upper sealing flange has an upper matching surface, the inner side of the lower sealing flange has a lower matching surface, the top of the sealing cover is fixedly installed with an oil cylinder, and the cylinder rod of the oil cylinder extends into the fixing sleeve and passes through the supporting part, and the supporting part There is a supporting plate at the bottom of the reactor, and the supporting plate is connected to the supporting part through the connecting rod. The internal sealing effect of the reactor is achieved through the close contact between the sealing part and the inner side of the upper sealing flange and the lower sealing flange. The overall sealing effect is good and will not Resulting in component wear, the sealing structure has a long service life.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a reaction kettle with a sealed heat preservation mechanism. Background technique [0002] Reactors are widely used in petroleum, chemical, rubber, pesticides, dyes, medicine, food, pressure vessels used to complete vulcanization, nitration, hydrogenation, alkylation, polymerization, condensation and other processes. Sealing and heat preservation are very important during the use of the reactor. Good sealing can prevent the leakage of toxic or odorous gas. Good heat preservation can effectively ensure that the actual temperature in the reactor is consistent with the temperature parameters required by the reaction, ensuring that the internal The chemical reaction is carried out effectively. The overall structure of the current reactor basically includes the reactor body and the sealing cover on the top. There are many types of sealing mechanisms between the sealing cover and the r...

Problems solved by technology

Sealing and thermal insulation are very important during the use of the reactor. Good sealing can prevent the leakage of toxic or odorous gas. Good thermal insulation can effectively ensure that the actual temperature in the reactor is consistent with the temperature parameters required by the reaction, ensuring that the internal The chemical reaction is carried out effectively. The overall structure of the current reactor basically includes the reactor body and the sealing cover on the top. There are many types of sealing mechanisms between the sealing cover and the reactor body, mainly in the structure of gaskets and sealing rings. , the structure of the gasket and sealing ring is mainly due to the short life cycle and is not easy to detect after wear and tear. It can only be detected when gas leakage occurs, which is easy to cause environmental pollution; in addition, the heat preservation measures of the current reactor are mainly in the sealing cover or the reactor body. Insulation material is added in the interlayer, and the thermal insulation performance has been recognized by users. However, the sealing cover is the position most in contact with the internal gas, and the thermal insulation of the sealing cover can be further strengthened.
