The function of glass lined stirrer

The production of chemical and pharmaceutical products is mostly achieved through the stirring process. The function of the agitator is to generate different liquid flow patterns in the mixing container, so that the materials in the container can be circulated in the main body, and the materials with various components can be heat transferred, mass transferred, dispersed, absorbed, suspended, emulsified and other processes between materials through the function of the loss agitator, so as to obtain the required chemical and pharmaceutical products.
Glass lined mixing containers are one of the most important products for industrial ceramic enterprises. The function of the stirrer is to achieve maximum contact between two or more substances in the container, and to form a sufficient mixture within the predetermined process time, which is conducive to specialized heat, mass transfer, and chemical reactions, so as to achieve the expected yield of the product. The correct design and selection of agitators can enable the materials in the mixing container to have a high reaction rate (referring to the degree of change in a certain substance per unit volume and per unit time of the container, which can be calculated using reaction products).
The material mixing process is complex, and its basic function is to realize the main circulation of materials and provide the required shearing. Different reaction processes require different main body circulation and shearing of materials in the container, and the agitator matching it must be selected correctly to obtain a better mixing effect. To achieve the expected production objectives, designers must pay attention to the above issues.
According to the different liquid flow patterns formed by agitators, agitators can be divided into two categories: axial flow agitators and radial flow agitators
Mixer. The liquid flow formed by an axial flow stirrer is formed by the pressure difference between the upper and lower surfaces of the stirrer blades, causing the liquid to flow from top to bottom or from bottom to top along the rotation axis direction. Paddle type agitators, push type agitators, and airfoil axial flow agitators all belong to axial flow agitators.
The liquid flow formed by a radial flow stirrer is formed by the centrifugal action of the stirrer, which throws the liquid radially and circumferentially towards the container wall, and then flows upwards or downwards along the wall. The impeller type agitator and anchor type (frame type) agitator belong to the agitators with radial flow as the main flow. In short, liquid stirring is to enable various materials involved in stirring to be fully mixed, and the requirements for the agitator vary depending on the liquid flow conditions of different types of stirring processes.
