Description

Technical Field

[0001] The invention relates to the field of chemical equipment, in particular to an adjustable-paddle fishtail stirring paddle and a stirring kettle using the stirring paddle. Background Art

[0002] In traditional stirring kettles, stirring paddles are often used for operations such as mixing materials and crystallization. When stirring different materials, the paddle type used is also different; when stirring materials that require high-intensity stirring, such as slurries, muds, and high polymers with high viscosity, inclined blades are usually used, because inclined blades have higher stirring capacity and can quickly break the static balance of materials. The oblique cutting design enables it to simultaneously generate axial flow and radial flow during the stirring process. This combined flow direction can achieve better mixing effects. However, the inclined blade has high resistance during stirring, and long-term stirring will lead to excessive energy consumption and increase operating costs. The straight blade has less resistance and relatively low energy consumption, which makes the straight blade suitable for materials or scenes that require long-term stirring, which can effectively reduce operating costs. However, the flow pattern generated during the stirring process is relatively single, and the stirring efficiency is lower than that of the inclined blade.

[0003] The straight blades and inclined blades of the agitator each have their own advantages and disadvantages, so when choosing, it is necessary to select the appropriate agitator blade type according to the specific material characteristics and stirring requirements. Among them, when adding materials with higher specific gravity or viscosity, in order to save energy, you can first use inclined blades to preliminarily mix the materials, and then replace them with straight blades for long-term stirring to make the materials evenly mixed. However, changing the paddle type during the stirring process is cumbersome, time-consuming and labor-intensive. In addition, the existing agitator blade structure is too simple, making it impossible to produce a complex flow field, thus affecting the mixing effect of the materials. Summary of the invention

[0004] In order to overcome the deficiencies in the prior art, the present invention provides a fishtail-type stirring paddle with an adjustable paddle and a stirring kettle using the stirring paddle; the stirring paddle for the stirring kettle of the present invention can adjust the paddle type according to the characteristics of the material to be stirred and the stirring requirements, and is easy to operate, and can reduce energy consumption and improve stirring efficiency; when stirring materials with higher specific gravity or viscosity, a combined stirring method can be used, first using an inclined paddle to quickly break the static balance of the material, and then adjusting the paddle type to a straight paddle for long-term stirring, thereby reducing energy consumption and effectively reducing operating costs.
