Production of resin with steam heating heat conduction oil circulation heating reaction kettle

Abstract

The invention discloses a steam-heating heat-conduction oil cyclic heating reaction kettle for producing resin. The steam-heating heat-conduction oil cyclic heating reaction kettle comprises a kettle body, a kettle cover and a power mechanism, wherein the power mechanism is positioned on the kettle cover; the power mechanism sequentially comprises a motor, a speed reducer, a rack and a stirring shaft positioned in the kettle body from top to bottom; an outer coil tube is arranged at the periphery of the kettle body in a surrounding mode; the outer coil pipe is formed by arranging a heat-conduction oil inner tube and a steam outer tube in a sleeving mode; a heat-insulating layer further covers the outer part of the outer coil tube; at least one cage-type stirrer is arranged on the stirring shaft; and at least one rack type stirrer is arranged at the lowest end of the stirring shaft. The reaction kettle disclosed by the invention is good in stirring effect, improved in reaction efficiency, good in heating effect, high in heating speed, good in thermal-insulation effect, small in heat loss and complete in reaction; and a heating device is set outside, so that the inner reaction space is saved, and the maintenance is convenient.

Description

technical field [0001] The invention relates to a reactor, in particular to a steam-heated heat-conducting oil circulating heating reactor for resin production. Background technique [0002] Reactors are widely used in the chemical industry and are an indispensable and important reactor in the chemical industry. At present, for the preparation of different chemical products, reactors suitable for their production will be manufactured according to their performance. In the reactor Generally, the stirring equipment is the main factor that directly determines whether the reaction is complete. Secondly, it is on the heating device of the reaction kettle. The general heating device is installed inside the reaction kettle. However, there is a disadvantage of setting it inside. It also occupies the reaction space inside the reactor, reducing the effective reaction space; again, the general reactor is heated by steam or heat conduction oil, and after heating, it is transported to th...

[0002] Reactors are widely used in the chemical industry and are an indispensable and important reactor in the chemical industry. At present, for the preparation of different chemical products, reactors suitable for their production will be manufactured according to their performance. In the reactor Generally, the stirring equipment is the main factor that directly determines whether the reaction is complete. Secondly, it is on the heating device of the reaction kettle. The general heating device is installed inside the reaction kettle. However, there is a disadvantage of setting it inside. It also occupies the reaction space inside the reactor, reducing the effective reaction space; again, the general reactor is heated by steam or heat conduction oil, and after heating, it is transported to the jacket in the reactor for heating reaction. The heating speed of this method is slow, the heating effect is poor, and the heating time is long, which affects the reaction efficiency
