Description

TECHNICAL FIELD

[0002] In the field of chemical production, the mixing of chemical raw materials is a crucial link, and its effect directly affects the quality and performance of the final chemical product. However, the existing chemical mixing device still has many problems, which seriously restricts the efficiency and quality of chemical production.

[0003] Firstly, the cleaning problem has always been a major problem in chemical mixing. Traditional mixing devices lack effective cleaning components. During the mixing process, chemical raw materials are easily left on the inner wall of the mixing tank, which not only causes waste of raw materials and increases production cost, but also may affect the quality of the next batch of chemical products. Moreover, the long-term accumulation of residual raw materials may corrode the inner wall of the mixing tank, shortening the service life of the equipment.

The stirring rod is usually directly fixed on the shaft, and the distance between them is relatively fixed, which cannot be quickly adjusted according to needs, resulting in a relatively fixed stirring area, making it difficult to flexibly adjust the distance between the stirring rods according to actual production needs, and unable to achieve the best stirring effect for different characteristics of chemical raw materials.

[0005] Thirdly, the mixing effect needs to be improved. Most of the existing mixing devices use a single stirring method, which is difficult to fully turn the materials at various positions in the mixing tank, especially the materials near the inner wall of the mixing tank, which may cause uneven mixing, resulting in uneven quality of chemical products.

[0006] In summary, in order to solve the above problems, the utility model provides a chemical mixing device of stirring.
