The Main Structure of Agitation Equipment and How to Select It

In the Agitation equipment, the structural type of the kettle body is usually a vertical cylindrical shape, and the ratio of the height to the diameter of the kettle body is mainly determined by the ratio of the height to diameter of the liquid in the container and the size of the charging factor. The ratio of the liquid to high-diameter of the container depends on the nature of the material in the container, the stirring characteristics, and the number of agitator layers. Generally, the ratio is 1 to 1.3, and the maximum is 6 at most.

The bottom of the kettle has a flat bottom, an elliptical bottom, a conical bottom, and sometimes a square kettle. At the same time, according to the heat transfer requirements of the process, jackets can be added to the outside of the kettle, and the heating medium such as steam and cooling water can be connected. When the heat transfer area is insufficient, coils can also be set inside the kettle body.

When selecting the agitation equipment, the shape and size of the stirring vessel should be determined according to the scale of production (ie, the material handling amount), the purpose of the mixing operation, and the characteristics of the material. When determining the volume of the stirring vessel, the charging coefficient should be reasonably selected to maximize the use of the device. rate. If there is no special need, the kettle body should generally use the most commonly used vertical cylindrical containers, and choose the appropriate cylinder height-to-diameter ratio (or the ratio of the liquid container height to diameter). If there is a heat transfer requirement, a jacket structure shall be provided on the outside of the kettle. The types of jackets include integral jackets, spiral baffle jackets, half-pipe jackets, and honeycomb jackets. The heat transfer effect increases sequentially, but the manufacturing cost increases accordingly.
