Mixing equipment

The structure of kettle body is usually vertical cylinder, and the ratio of height to diameter is mainly determined by the ratio of height to diameter of the container and the loading coefficient. The ratio of height to diameter of the container varies according to the nature of the material in the container, stirring characteristics and the number of stirrer layers. Generally, the ratio of height to diameter of the container is 1-1.3, which can reach 6 when it is large. The bottom of the pot has flat bottom, elliptical bottom, conical bottom and so on. Sometimes it can also be used as a square kettle. At the same time, according to the heat transfer requirements of the process, the outside of the kettle can be jacketed with steam, cooling water and other heat-carrying media; when the heat transfer area is insufficient, the inner part of the kettle can also be set up coil.
When choosing the agitating vessel, the shape and size of the agitating vessel should be determined according to the scale of production (i.e. the amount of material handled), the purpose of agitating operation and the characteristics of the material. In determining the volume of the agitating vessel, the charging coefficient should be reasonably selected to maximize the utilization rate of the equipment. If there is no special need, the kettle body is generally suitable to choose the commonly used vertical cylindrical container, and choose the appropriate height-diameter ratio of the cylinder body (or the height-diameter ratio of the container filled with liquid). If there is heat transfer requirement, the jacket should be provided with jacket structure. The types of jackets include integral jacket, spiral baffle jacket, half pipe jacket and honeycomb jacket. The heat transfer effect is improved in turn, but the manufacturing cost is also increased accordingly.
