As a common extraction equipment, the structure optimization of extraction tank can effectively improve the performance and meet the increasing requirements of industrial production.

Firstly, the structure optimization of the mixing chamber is the key. In some cases, the traditional stirring paddle may not be able to achieve sufficient mixing of the two-phase liquid, resulting in low extraction efficiency.

New impeller designs can be used, such as multi-stage impeller or combined impeller.

Multi-stage mixing paddle can provide different mixing intensity in different areas, first at the entrance of the mixing chamber using high intensity mixing, so that the two-phase liquid quickly dispersed, and then in the subsequent area using lower intensity mixing, to maintain a uniform mixing state of the liquid, thereby improving the mass transfer efficiency.

The combined agitator combines the advantages of different types of agitator, such as the combination of turbine agitator and paddle agitator, to give full play to their advantages in different aspects.

Secondly, the structure of the clarifying chamber can also be optimized. Adding separation elements such as inclined plates or inclined tubes in the clarifying chamber can increase the settling area of the liquid and improve the separation efficiency.

The installation Angle and spacing of the inclined plate or inclined pipe need to be reasonably designed according to the nature and flow rate of the liquid. At the same time, an overflow weir or other liquid level control device is set at the outlet of the clarifying chamber to keep the liquid level stable and reduce the entrain phenomenon.

In addition, the overall layout of the extraction tank can also be improved. For the multistage extraction tank, the connection mode between the stages can be optimized to reduce the resistance and backmixing of the liquid in the flow process.

For example, the use of reasonable pipeline layout and diversion devices, so that the liquid can be smooth and smooth flow between levels. In addition, in order to improve the sealing of the extraction tank and reduce the volatilization and leakage of solvent, the sealing structure of the extraction tank can be optimized.

The use of new sealing materials and sealing methods, such as mechanical seals or lip seals, to ensure that the equipment is well sealed during operation.

By optimizing the structure of the mixing chamber, clarifying chamber, overall layout and sealing structure of the extraction tank, the mixing effect, separation efficiency and sealing of the extraction tank can be effectively improved, and the overall performance can be improved, so as to provide more efficient and stable extraction equipment for industrial production.
