Problems solved by technology

[0003] Among them, the stirring device is an important part of the reactor. Most of the existing reactor stirring devices are in the form of conventional stirring paddles, mainly including anchor type, paddle type, turbine type, pusher type, frame type, etc. Large, when there are many raw materials in the reactor, the stirring effect of the conventional stirring paddle is poor

Abstract

The invention provides a chemical reaction kettle which comprises a kettle body, wherein the top of the kettle body is provided with a feed port; the bottom of the kettle body is provided with a discharge port; the inside of the kettle body is provided with a feed plate and a stirring shaft; the feed plate is an inverted bowl-shaped structure; the external edge of the feed plate is connected with the inner wall of the kettle body; the feed plate is provided with a plurality of feed holes; the upper end of the stirring shaft penetrates through the feed plate, extends out of the kettle body and is connected with a motor positioned on the top of the outer side of the kettle body; the stirring shaft below the feed plate is provided with a first stirring paddle and a second stirring paddle; the second stirring paddle is positioned on the bottom end of the stirring shaft; and spiral blades are arranged between the two stirring paddles. The inverted feed plate arranged in the chemical reaction kettle ensures the liquid feed uniformity no matter when the liquid feed amount is small or large; and the three-layer-structure stirring device can perform the stirring function more sufficiently, thereby enhancing the reaction rate.

Description

technical field [0001] The invention belongs to the field of chemical equipment, and in particular relates to a chemical reaction kettle. Background technique [0002] Reactor is an important chemical equipment, and it is a pressure vessel mainly used to complete chemical processes such as vulcanization, nitration, hydrogenation, alkylation, polymerization, and condensation. According to different reaction conditions, the structural design of the reaction kettle will be different, but its structure is generally composed of a kettle body, a transmission device, a stirring device, a heating device, a cooling device, and a sealing device. [0003] Among them, the stirring device is an important part of the reactor. Most of the existing reactor stirring devices are in the form of conventional stirring paddles, mainly including anchor type, paddle type, turbine type, pusher type, frame type, etc. Large, when there are many raw materials in the reactor, the stirring effect of the...
