Horizontal oil heating hollow blade bearing reaction kettle

Abstract

The invention provides a horizontal oil heating hollow blade bearing reaction kettle, and is used for solving the problem in the prior art that the heating effect is bad when heat conduction oil is used for heating viscous materials. The reaction kettle comprises a reaction kettle barrel which is horizontally arranged, wherein the reaction kettle barrel is internally provided with a hollow shaft, a plurality of hollow blades communicated with the hollow shaft are fixed on the hollow shaft, and an oil inlet end and an oil outlet end are respectively arranged at both ends of the hollow shaft; an upper jacket positioned on the outer surface is fixed at the upper half part of the reaction kettle barrel, and an upper cavity is formed between the upper half part of the reaction kettle barrel and the upper jacket; a lower barrel positioned on the inner surface is fixed at the lower half part of the reaction kettle barrel, a lower jacket is arranged at the part of the reaction kettle barrel positioned under the lower barrel, and a lower cavity is formed between the lower barrel and the lower jacket; the lower jacket is provided with an oil inlet; a cavity opening communicating the upper cavity and the lower cavity is formed in the reaction kettle barrel; and the upper jacket is provided with an oil outlet. Through a double heating manner of the jackets and the hollow blades, the reaction kettle greatly improves the heating efficiency, and the hollow blades can achieve the effect of stirring materials; and the reaction kettle is suitable for viscous materials.

Description

technical field [0001] The invention relates to the technical field of horizontal reactors, in particular to a horizontal oil-heated hollow blade pressurized reactor. Background technique [0002] At present, most of the reactors on the market are vertical reactors with vertical stirring. The stirrers include anchor type, frame type, paddle type, turbine type, pusher type, etc. These structural forms are not suitable for large diameter, low speed and relatively large reaction materials. Viscous situation. The up and down stirring effect of the materials in the kettle is poor, the temperature difference is large, and the uniformity is poor. Even if a draft tube is installed, there is not much improvement. When the slurry reaches a certain concentration, the material in the kettle will seriously stick to the wall, affecting heat transfer. In addition, the rotation speed of the stirring shaft of the vertical reactor is generally 100-400 rpm, which increases the difficulty of ...
